Configured verification grants now match ordinary environment, RTK and temporary-output variants across dispatches. Validated regex grants can cover a user-approved command family; compound shell operations request consent while retaining concrete segment guards.

Diagnosis

The repeated consent loop came from command identity: ordinary prefixes and redirects remained distinct, and most temporary operands retained their absolute dispatch path. The initial python3 -m unittest discover -s tests -p test_consent_variants.py reproduction failed six env/RTK combinations across resolve and rereview. Matching and normalization now share the configured argv and verified temporary-path membership. Compound source has a separate whole-operation identity, and a grant for one segment does not authorize another.

This is a shared-cause root fix within #439's approved scope, including the compound handling absorbed from #455. Related-work searches covered open and closed consent issues and the linked #398, #406, #450, #455, #460 and #464. #455 remains open pending native executor parity verification.

Unit Behaviour Files Tests Verification Rollback
WU-1 Shared consent matching, validated regex storage and approval, shell segment guards and refusal layers stage_permissions.py, grants.py, command_permissions.py, cycle.py, executors.py, user_choices.py; owning docs and test registrations test_consent_variants plus existing consent, Compose, hook and journal regressions Agent-reported verification below independent: revert this commit

Documentation

Updated the owning host-permissions and configuration pages for variants, matcher validation, proposal and edited-answer fields, compound handling, persistence and layers. Updated the parity audit (PA-19 and new PA-43 read-consent row) and ROADMAP_V2 for #439/#455. Existing behavior was documented; the new matching and pattern contract is documented in this PR.

Security review

cc-security-review ran over command normalization, regex evaluation, approval/storage, generated host rules, segment guards, execution evidence and refusal attribution. Fixed issues found during implementation: control-keyword and heredoc-header guard omissions, configured-check matching that could ignore Compose drift, and literal configuration prefixes accepting an empty shell argv. Regression coverage retains Git, credential and outside-TMPDIR redirect guards. Regex evaluation uses a bounded subprocess; matching never executes the proposed command.

Residual risk: shell/interpreter internals and dynamically constructed commands require external isolation, as disclosed in consent. Native Claude/Codex parity is not verified in this nested environment; Bash process comparisons and real hook subprocess checks are separate evidence. No claim of native parity or merge readiness is made.

Verification (agent-reported)

On head 5c3679a43dafb09fcb078fee9e7f7f8a3aed2f86: python3 -m unittest discover -s tests passed (2,527 tests, one skipped; 2,526 executed), the 16 issue-specific regression tests passed, basedpyright reported zero errors/warnings, and python3 scripts/validate-package.py passed. The suite uses disposable fixture state rather than user-global Git identity or credentials. Native executor parity remains required and unverified; tests.conclusion is not_verified, with AC-8 open. The final summary comment carries the complete tests.version=2 checks and attempt receipt. Code-host CI is read once after upload under the parallel policy.

Refs #439. Compound implementation also addresses #455; keep #455 open until integrated native verification completes.

Code Cycle initial review — PR #468 (work item #439)

[CCR-20261109-001] · senior_reviewer · anthropic/claude-opus-5-5→? · high · schema:2

Verdict: CHANGES_REQUESTED on head 5c3679a43dafb09fcb078fee9e7f7f8a3aed2f86. Blocking findings: REV-001, REV-002.

Summary and scope

I reviewed the full accumulated diff origin/main...5c3679a (merge base eaadf5494b4c3c4c4acd25e72f34fc4950c1e5fa, 19 files, +1053/−101, 1827 diff lines read in sections). It covers configured-check variant matching, $TMPDIR path normalization across dispatches, validated regex (pattern) grants, compound shell consent with per-segment guards, execution evidence in ConsentStore, refusal layer labels, and the docs, parity-audit and roadmap updates. I did not read the one-line JSON characterization fixture (tests/fixtures/cycle_stage_characterization.json, 12 changed lines) in full because it is too large for the reader. The test suite exercises it.

The configured-check variants, the cross-dispatch $TMPDIR placeholders, regex validation, layer labels and docs match the acceptance criteria, and every configured check passes. The defects are in how regex grants and the segment guards handle compound shell source, which is the security boundary AC-8 and AC-10 describe.

Findings

[REV-001] · high · open · - · blocks:yes — Regex grants match raw compound shell source, so a simple-command pattern authorizes other segments

Paths: scripts/stage_permissions.py (matching_answer L3259–3271, normalized_command L3278–3279, check L699–729), docs/host-permissions.md (Reusable command consent).

For a compound command, operation() returns {"words": ["<SHELL>", source]}. normalized_command returns that raw source, and matching_answer runs re.fullmatch(pattern, source). protected_reason only refuses segments that hit the Git, credential or redirect guards. Any other segment rides along. Traced through check(): with the pattern your own test uses as the agent proposal, cat /outside/api/.+ (validated with positive cat /outside/api/schema.json and negative cat /outside/secrets), these are all allowed with no new question:

  • cat /outside/api/x; rm -rf /outside/project
  • cat /outside/api/x | sh
  • cat /outside/api/x && curl -d @file https://…

A pattern such as cat [^;&|]+ also covers cat $(printf ~)/.codex/auth.json, because the substitution builds the path at run time and the static guard never sees it.

This contradicts AC-8 ("a grant for one segment never extends to another") and the new docs ("a grant for a simple segment never authorizes a pipeline or another segment"). The user approves something that reads like one command family, and the toolkit then authorizes arbitrary chained commands.

Fix: for a <SHELL> operation, apply a regex grant only when every segment's normalized text fullmatches it on its own, or when the user explicitly approved it as a compound pattern and the question says so. Add regression tests for <positive>; rm x, <positive> | sh and <positive> $(…).

[REV-002] · medium · open · - · blocks:yes — The segment credential guard compares literal paths, so cd options, pushd and globs get past it

Paths: scripts/stage_permissions.py (protected_reason L3307–3319 and L3359–3366, credential_reason L3378–3387).

Compound handling tracks cd to guard cd ~/.codex; cat auth.json. Three cases get through:

  • cd -P ~/.codex && cat auth.json: -P is taken as the target, so the next cwd is <cwd>/-P.
  • pushd ~/.ssh; cat id_rsa: pushd is not tracked.
  • Unquoted globs such as cat ~/.codex/auth* or cat ~/.ss?/id_rsa: the guard resolves the literal glob text, which never equals a store path.

All of these are static forms the PR now accepts as compound commands. With an exact grant or a matching pattern, the toolkit authorizes a credential-store read that AC-10 says "grants nothing". The external sandbox's credential denials still apply where they are active. The toolkit guard is the part that is wrong.

Fix: skip option words for cd, handle pushd/popd, and fail closed when a segment changes the directory to an unknown place before a relative operand. Match glob operands against the store paths (for example with fnmatch on the expanded prefix). Add tests for each form.

[REV-003] · medium · open · - · blocks:no — Every consent question names the configured test command, even for unrelated commands

Paths: scripts/command_permissions.py L241–244, scripts/grants.py L548–562.

refused_operation sets configured_command = policy.test_command whenever the operation is not a verify: check, so a refusal of cat /outside/api/schema.json asks "…Configured command: python3 -m unittest discover -s tests." The prompt also cuts the requested command to 60 characters (it was 140). The person answering sees a truncated command next to an unrelated full one. AC-2 asks to name the configured command for variants of it, not for every question.

Fix: set configured_command only when the refused command is a variant of a configured check (for example, the same underlying runner after command_parts), and keep the requested command readable in the prompt.

[REV-004] · medium · open · - · blocks:no — An invalid edited pattern, or forever for review, ends the whole cycle instead of asking again

Paths: scripts/grants.py L886–895 and L979–985; scripts/run_cycle.py L3337–3339.

The structured answer path calls make_pattern_grant without catching GrantError. terminal_prompt accepts any JSON answer in ANSWERS, including forever for review/rereview, which apply_answer rejects. Either error leaves ConsentBroker.request and reaches run_cycle.main, which exits with code 2. A typo in an edited regex therefore stops the running cycle. Unlike the proposal path (command_permissions.py L231–233), an edited pattern is also not checked to cover the refused command.

Fix: catch GrantError in request, show the reason, and ask again. Check that the edited pattern covers the refused normalized command.

[REV-005] · low · open · - · blocks:no — The "Codex" AC-8 parity test does not exercise Codex

Path: tests/test_consent_variants.py L638–663.

test_ac8_codex_shell_baselines_and_guarded_execution is the Claude test with a different executor label on the grant. sp.check is the Claude hook, and a Codex stage has no command table, so the test proves nothing Codex-specific. The PA-19 baselines (claude -p / codex exec) are still unverified, as the PR says. AC-8 stays open.

Fix: rename the test, or assert the Codex-side invariant the way PA-18's conversion did. Keep the native baselines as separate frozen checks.

Security triage and audit

  • The deterministic rule did not fire. .code-cycle.yml declares no security_review.always_when, and no changed path matches the mandatory minimum (CI, secrets, agent configuration).
  • Reviewer triage and the runtime plan (security_required) both require the audit. The change rewrites the command-permission hook, consent storage, credential guards and the generated host --allowedTools rules.
  • cc-security-review ran on head 5c3679a. It found REV-001 and REV-002.
  • Also reviewed with no finding: regex evaluation, which runs in a separate python3 -I process with JSON stdin, a 500 ms timeout and length limits; structural ReDoS rejection; pattern validation before saving; consent-store schema compatibility; the Bash(*) host rule, which is disclosed in the docs and keeps the hook as the gate; and executed_commands evidence, which never creates authorization.

Commands executed

Check Command Result
configured-test (required) python3 -m unittest discover -s tests exit 0, Ran 2527 tests in 283.484s, OK (skipped=1)
validate-package python3 scripts/validate-package.py exit 0, VALID: 16 skills (7 cycle, 9 supporting)…
basedpyright basedpyright exit 0, 0 errors, 0 warnings, 0 notes
unittest-default python3 -m unittest exit 0, Ran 0 tests (default discovery finds no tests at the root)

Unverified

  • Not reproduced by running them: REV-001 to REV-004. They come from tracing the code at the reviewed head. The probe python3 -I -c "…sp.check(…)…" was refused by this review stage's command table (command_69f00e1bf1516c6eb0880ee2054a437e463bbeee84b3fdaefd27006a7f168b7f, accessory, not essential). I skipped it rather than trying to get around the refusal.
  • AC-8: native Claude/Codex executor parity for PA-19 is not verified (not_verified).
  • Fixture: the characterization fixture diff was not read line by line.

CI (parallel policy, read once)

Check State
Skills, manifests, and Bash installer pass
Windows test shard (windows-1) pending
Windows test shard (windows-2) pass
Windows test shard (windows-3) pending
Windows test shard (windows-4) pending

The cycle's CI gate decides on the pending shards.

Residual risk

  • What runs inside shell, interpreter and $(…) code is opaque to the hook. As the PR discloses, only external isolation constrains it.
  • Every regex grant spawns a Python process inside the hook for each match. Under load, a match that times out grants nothing and the question comes back.
  • executed_commands keeps full command text in consents.json.
  • Any exact configured-check or compound grant also widens the generated host --allowedTools to Bash(*).

Resolution completed for PR #468 / work item #439 at 5b6ff3aa57253d86f22b960ee8f1b2d0f9a7b7b6. All five findings are addressed in commit 5b6ff3a, pushed successfully and confirmed as the PR head. Required native parity remains unverified; this is not merge approval.

[CCR-20261109-001] · senior_reviewer · anthropic/claude-opus-5-5→? · high · schema:2

[CCT-20261109-001] · deep_coder · openai/gpt-6.1-sol→? · high · triaged:5c3679a43dafb09fcb078fee9e7f7f8a3aed2f86 · schema:2

All dispositions were frozen as valid before source edits against the triaged SHA. Recovered both provider comments from trusted author datacas; there were no review threads or ID collisions.

[REV-001] · high · resolved · valid · blocks:yes — Regex grants match raw compound shell source, so a simple-command pattern authorizes other segments

Added an explicit compound: true approval bit. Existing regex grants match simple commands only; proposals, edited answers, authorization and execution audit share this rule. The question discloses authorization of all matching shell segments before variable-length text. Regression tests cover chained deletion, pipelines, substitutions, stored compound approval, and long regex warnings.

[REV-002] · medium · resolved · valid · blocks:yes — The segment credential guard compares literal paths, so cd options, pushd and globs get past it

Credential guards now account for cd options, pushd/popd and -n, unknown directory changes, failed/conditional/subshell changes, relative transitions, logical and physical paths, glob/brace operands and symlinked credential-store spellings. Analysis checks possible working directories without reading credentials. Regressions include the original cases and the additional cases found in the delegated security review.

[REV-003] · medium · resolved · valid · blocks:no — Every consent question names the configured test command, even for unrelated commands

Configured-command context is attached only to requests sharing a configured runner after environment/RTK unwrapping. Unrelated file reads omit it. Restored the requested-command preview to 140 characters; the accompanying permission record retains the complete command.

[REV-004] · medium · resolved · valid · blocks:no — An invalid edited pattern, or forever for review, ends the whole cycle instead of asking again

Interactive validation now shows the rejection reason and asks again. Edited matchers must cover the original refused operation; malformed example lists, invalid regexes and unavailable global review grants cannot save authorization. EOF preserves the original pending request. Exact requests retain their existing diagnostic shape; all six characterization tests pass without changing the fixture.

[REV-005] · low · resolved · valid · blocks:no — The "Codex" AC-8 parity test does not exercise Codex

Renamed and clarified both tests as shared-hook checks with executor grant metadata. They explicitly make no claim about Codex enforcement or native executor parity. The two native frozen checks remain required and unverified, so AC-8 and #455 remain open.

Post-change review: cc-code-review and cc-security-review ran on the complete fix delta from trusted review base 5c3679a43dafb09fcb078fee9e7f7f8a3aed2f86, verified as an ancestor of the new head. The delegated passes found additional directory-state, malformed-input and warning-disclosure cases; these were fixed and covered before the final clean pass. No confirmed P0/P1 finding remains in that delta. security_audit_ran=true.

Agent-reported local verification: the final full suite passed 2,536 tests, one skipped (2,535 executed), in 924.804 seconds. All 25 issue regressions and 6 characterization tests passed; package validation passed; BasedPyright reported zero errors, warnings and notes. An earlier development full run failed one characterization comparison; the redundant diagnostic field was removed, and the unchanged fixture and final suite passed. Tests use disposable fixture state; GitHub authentication is used only for authorized publication. Linux verification does not establish the Windows CI results.

Native Claude/Codex PA-19 parity did not run. The observed host marker is CODE_CYCLE_STAGE_EXECUTOR=codex; nested Codex is subject to the supplied socket-mask restriction, and safe Codex-to-Claude sandbox compatibility remains unverified. Shared-hook and Bash-process checks are separate evidence. The frozen native checks keep tests.conclusion=not_verified and AC-8 open. #455 remains open.

The owning host-permissions/configuration pages and PA-19/PA-28 audit rows document the fixes. The accumulated PR already updates ROADMAP_V2 for #439/#455. Residual risk: dynamically constructed shell/interpreter internals still depend on external isolation. Possible-directory analysis is conservative; unresolved relative operands require an inspectable absolute path.

CI (parallel policy, read once after upload): GitHub confirmed the exact pushed head and returned an empty statusCheckRollup. No check execution state was available in that snapshot. The six workflow checks below were expected but missing; they count in checks.failed per the reporting contract, not as observed failed job executions. There were 0 passed, 0 pending, 6 missing. No polling or CI fix round ran; the cycle's CI gate handles subsequent state.

Verdict: CHANGES_REQUESTED on head 5b6ff3aa57253d86f22b960ee8f1b2d0f9a7b7b6 (previous review: 5c3679a43dafb09fcb078fee9e7f7f8a3aed2f86). Blocking findings: REV-006, REV-008.

What changed since the previous review

Commit 5b6ff3a (7 files, +361/−67) adds an explicit compound: true opt-in for regex grants, tracks cd options, pushd/popd and possible working directories in the segment credential guard, matches glob and brace operands against the credential stores with fnmatch, limits the configured-command text to requests that use the same runner, and makes invalid consent answers ask again. I re-read the complete accumulated diff (origin/main...5b6ff3a, merge base eaadf5494b4c3c4c4acd25e72f34fc4950c1e5fa, 2207 lines) with the focus on this delta.

Previous findings

[REV-001] · high · resolved · valid · blocks:yes — Regex grants match raw compound shell source, so a simple-command pattern authorizes other segments

grants.pattern_covers_operation refuses <SHELL> operations unless the stored grant has compound: true. matching_answer, the proposal path, edited answers and record_executions all use it. The question says "Compound pattern: all segments of matching shell source are authorized", and that text comes before the truncated command. Verified by running test_rev001_simple_pattern_never_authorizes_compound_shell (; rm, | sh, && curl, $(…) in resolve and rereview), the compound-approval storage test and the long-regex warning test. All pass.

[REV-002] · medium · resolved · valid · blocks:yes — The segment credential guard compares literal paths, so cd options, pushd and globs get past it

The three forms reported in the previous review are now refused: cd -P/-L, pushd/popd (including -n) and glob/brace operands. The guard also covers conditional and subshell cd and symlinked store spellings. Verified by running test_rev002_*, which covers the original forms and 15 more. All pass. Two other static forms still get past the same guard, and the fix created a new hard refusal. They are reported separately as REV-008 and REV-006.

[REV-003] · medium · resolved · valid · blocks:no — Every consent question names the configured test command, even for unrelated commands

refused_operation sets configured_command only when the first word after env/RTK unwrapping equals the runner of the test command or a verify prefix. The preview is back to 140 characters. Verified by running the regression suite. In this repository every python3 … request still names the configured test command. That is the runner-level rule the previous review suggested.

[REV-004] · medium · resolved · valid · blocks:no — An invalid edited pattern, or forever for review, ends the whole cycle instead of asking again

ConsentBroker.request catches GrantError and asks again with validation_error. An edited pattern has to cover the refused operation. EOF leaves the request pending. apply_answer reports the global-role error before the store check. Verified by running test_rev004_invalid_answers_retry_without_saving_rejected_grants for resolve and rereview and the 6 characterization tests. All pass.

[REV-005] · low · resolved · valid · blocks:no — The "Codex" AC-8 parity test does not exercise Codex

The tests are renamed test_ac8_shared_hook_with_{claude,codex}_grant_metadata and no longer claim native parity. The native PA-19 checks are still frozen, required and unverified.

New findings

[REV-006] · medium · open · - · blocks:yes — A relative argument after cd "$VAR" is refused with no consent question, even when it is not a path

Paths: scripts/stage_permissions.py L3318–3322 (and the segment_cwd = None branch at L3349–3352), docs/host-permissions.md L211.

When a cd/pushd target contains $, a backquote or a glob character, or pushd/popd has no known stack, the possible working directory becomes None. After that, any later word that does not start with - and is not absolute returns the guard "cannot guard relative operands after an unresolved directory change". check() turns it into compound_guard, and refused_operation skips guarded operations, so no question is asked and no grant can ever cover it. The test is not limited to path-like words. Traced on this head:

  • cd "$REPO_ROOT" && make test: test is a make target.
  • cd "$(git rev-parse --show-toplevel)" && pytest tests
  • cd "$X" && echo done

Each is refused permanently. Only $HOME and $TMPDIR expand in the parser (_shell_segments L569–583), so any other variable triggers this. The docs call it a credential guard ("receive no grant; use an explicit absolute path"), but these arguments are not credential-store reads. This is a new toolkit-only veto on a compound form that AC-8 says must ask for consent and run after it ("are no longer refused by parse_command … the operation runs after consent"). AGENTS.md treats such a veto as a finding. The previous review suggested "fail closed", and this implementation takes that further than intended. A guard that cannot inspect the operation should ask, with the risk stated. It should not refuse with no question.

Fix: when the directory is unresolved, refuse only operands that could name a protected store. For example, refuse when a trailing part of any store path (auth.json, .codex/auth.json, id_rsa, .ssh/…, hosts.yml, …) matches the operand or its glob. Otherwise ask the ordinary consent question with a warning that the directory cannot be inspected. Add regressions for cd "$X" && make test (asked, then runs after consent) and cd "$X" && cat auth.json (still guarded).

[REV-007] · low · open · - · blocks:no — Glob credential matching lets * cross /, so unrelated absolute globs count as credential reads

Path: scripts/stage_permissions.py L3446–3452 (credential_reason).

fnmatch.fnmatchcase(str(root), str(prefix)) compares whole path strings, and in fnmatch * and ? also match /. Every parent of a glob operand is compared too. So /home/*, a parent of ls /home/*/project, matches /home/<user>/.ssh, and the command is refused as credential_guard with no question. The same happens with ls ~/* (bash's * does not even match dotfiles), du -sh /h*, and a quoted operand such as find /home -path "/home/*/x" in a simple command. On main these reached the ordinary consent question. The scope is narrow, but each case is a new hard refusal of a non-credential read.

Fix: match path components one at a time (each fnmatch limited to a single part), and stop treating a prefix as a match when its last part is only a wildcard over a non-dot name. Add negative tests for ls /home/*/project and ls ~/*.

[REV-008] · medium · open · - · blocks:yes — builtin cd, command cd and CDPATH still get past the segment credential guard

Path: scripts/stage_permissions.py L3326 (protected_reason compound loop).

Only segments whose first word is exactly cd, pushd or popd change the tracked directory. These static forms change the shell's directory and are not tracked:

  • builtin cd ~/.codex; cat auth.json and command cd ~/.ssh && cat id_rsa: the first word is builtin/command.
  • CDPATH=~ cd .codex; cat auth.json and export CDPATH=~; cd .codex; cat auth.json: command_parts drops the assignment and the guard resolves .codex against the current directory, but bash resolves it through CDPATH to ~/.codex. CDPATH is handled nowhere in scripts/ except install.sh.

In each case cat auth.json is checked against the clone, so with an exact or compound: true pattern grant the toolkit authorizes a credential-store read that AC-10 says "grants nothing". This is the same class as REV-002. The external sandbox denials (~/.codex/auth.json, ~/.ssh, …) still apply where they are active. The toolkit guard is the part that is wrong. Traced, not executed (see Unverified).

Fix: treat builtin cd/command cd (and builtin/command with pushd/popd) as directory changes, and treat any CDPATH assignment or export in the source as an unresolved directory change. Together with the REV-006 fix, an unresolved directory then means "guard operands that could be credential tails, ask for the rest". Add regressions for each form.

Security triage and audit

  • The deterministic rule did not fire. .code-cycle.yml declares no security_review.always_when, and no changed path matches the mandatory minimum.
  • Triage and the runtime plan (security_required) both require the audit. The delta changes the credential guard, consent matching and answer handling.
  • cc-security-review ran on head 5b6ff3a, focused on the fix delta and the accumulated diff. It confirmed the REV-001 fix (no implicit compound authorization; observed metadata still matches exact words only) and found REV-008. REV-006 and REV-007 are parity and over-refusal problems, not vulnerabilities.
  • Reviewed with no finding: edited-answer validation, which builds a new grant and saves nothing before validation; the reordered global-role check; compound type validation; the cap of 64 possible directories, after which the set collapses to None; and the fact that the guard never reads the credential paths.

Unverified

  • REV-006, REV-007 and REV-008 come from tracing the code at this head. The probe python3 -I -c "…sp.protected_reason(…)…" was refused by this stage's command table (command_287b481b1289bda97b3bf306ef4c2d53236463d552b5c945989e91ca20bb41b6, accessory). I did not try to get around the refusal. The existing test cd $target; cat auth.json, which asserts a guard, confirms the None-cwd path that REV-006 relies on.

Residual risk

  • Interpreter, eval and $(…) internals are opaque to the hook. Only external isolation constrains them, as the PR discloses.
  • The segment credential guard is a static best effort. REV-008 shows that it needs a fail-safe rule for directory changes it cannot model, and REV-006 shows that this rule must ask rather than refuse.
  • An approved compound: true regex authorizes every segment of matching source. Only the regex and the per-segment guards limit it.

REV-006: after a directory change the hook cannot resolve, only relative
operands that may name a credential store keep the guard; every other
operand gets the consent question with an unresolved-directory warning.

REV-007: credential glob matching compares one path component at a time
with the bash dotfile rule, bracket expressions and literal working
directory parts; the matcher is iterative and the guard fails closed.

REV-008: builtin/command cd, pushd and popd, env -C/--chdir, CDPATH and
eval/source/./trap/alias are tracked as directory changes.

Code Cycle resolution — PR #468 (work item #439)

The resolution is complete at 496c6fc1725863549e62453e8f03676aec6e16ea, the confirmed head of this PR. The three rereview findings (REV-006, REV-007, REV-008) are fixed in commit 496c6fc, which was pushed. The required native PA-19 parity checks remain unverified, so AC-8 and #455 stay open. This is not merge approval.

All three new findings were triaged against 5b6ff3a as valid before any source edit. Their dispositions are frozen. REV-001 to REV-005 keep their earlier dispositions. The full comment history was recovered from the trusted author datacas. There are no review threads and no ID collisions.

Findings resolved in this round

[REV-006] · medium · resolved · valid · blocks:yes — A relative argument after cd "$VAR" is refused with no consent question, even when it is not a path

Paths: scripts/stage_permissions.py, scripts/command_permissions.py, scripts/grants.py, docs/host-permissions.md.

After a directory change that cannot be resolved, the unknown directory is treated as possibly any directory. A relative operand is still refused when it could name a credential store. It can do that in four ways:

  • It spells the rest of a store's path from one of its parents, such as auth.json, .codex/* or *.
  • It names a store's parent under the home directory: .codex, .claude or .config.
  • Its last part could name a file kept in a directory store: id_*, *_rsa, *_key, *.pem, known_hosts, credentials, config or hosts.yml.
  • One of its parts is a token-cache directory: sso or cli.

Only the parts after the last .. are considered. name=value words and attached short-option values are checked as well. Every other operand gets the ordinary consent question. The question carries WARNING: a directory change cannot be resolved…, and the request carries "unresolved_directory": true.

These now ask, and run after consent in both resolve and rereview:

  • cd "$X" && echo done
  • cd "$REPO_ROOT" && make build
  • cd "$(git rev-parse --show-toplevel)" && pytest tests
  • cd "$X" && cat config/settings.py

These are still guarded:

  • cd "$X" && cat auth.json
  • … cat .codex/*
  • … cat ../user/.s?h/id_*
  • … dd if=id_rsa …
  • … tar czf $TMPDIR/a.tgz .codex
  • … cat config

[REV-007] · low · resolved · valid · blocks:no — Glob credential matching lets * cross /, so unrelated absolute globs count as credential reads

Path: scripts/stage_permissions.py (credential_reason, _reaches, _part_matches).

Credential globs are now matched one path component at a time, the way bash expands them. A leading * or ? does not match a dotfile unless the source mentions dotglob/GLOBIGNORE, or the inherited BASHOPTS/GLOBIGNORE enables it. A bracket expression, including [^x] and [[:alpha:]], matches one character. A .. after a glob, inside braces, or in a brace alternative that holds / or ~ can lead to any directory. Components of the working directory are compared literally.

The matcher is iterative, so its work is bounded by pattern length times store length. A path with 990 ** parts no longer raises RecursionError. protected_reason now refuses if the guard fails unexpectedly.

ls <users>/*/project, ls ~/*, du -sh /h* and find … -path "<users>/*/x" reach the consent question again. ls ~/.*, cat ~/{x,.ssh}/id_rsa, cat ~/.s[^x]h/id_rsa and tar -C~/.ssh … are still guarded.

[REV-008] · medium · resolved · valid · blocks:yes — builtin cd, command cd and CDPATH still get past the segment credential guard

Path: scripts/stage_permissions.py (_compound_analysis, _directory_builtin, _env_chdir).

The guard now unwraps builtin and command (including command -p and --) before it tracks a cd, pushd or popd. command -v cd only describes the builtin, so it is not treated as a directory change. When CDPATH is set in the environment or appears in the source, a relative cd/pushd target counts as unresolved.

These also make the directory unresolved, including when called through builtin or command: eval, source, ., trap and alias. env -C and --chdir are handled too, including combined short options (-vC, -iCdir) and abbreviations such as --chd=. In each case the later cat auth.json, cat id_rsa or cat .credentials.json is guarded.

Post-change review and security

  • Delta base. Under the parallel CI policy, the delta was reviewed from the trusted rereview base 5b6ff3aa57253d86f22b960ee8f1b2d0f9a7b7b6, after confirming it is an ancestor of the new head.
  • Delegated review. A delegated cc-code-review and cc-security-review pass found one P1 in the first draft of this fix: a narrower name check let some credential reads after an unresolved cd reach the consent question. It also found several P2s: unbounded ** recursion, loaders called through builtin/command, trap, env -C, glob characters in the working directory, bracket expressions, braces containing /, option values, and dotglob from the environment. All of them are fixed and covered by tests.
  • Second pass. It found no P0 or P1 regression and no bypass relative to 5b6ff3a. It raised three P2s, which are also fixed: a store's parent directory named on its own, config, and env option spellings.
  • Security gate. The deterministic security_review.always_when rule did not fire. The audit ran because the plan sets security_required and the change touches the credential guard. security_audit_ran=true.

CI (parallel policy, read once after the push)

GitHub confirmed the head 496c6fc1725863549e62453e8f03676aec6e16ea. Its statusCheckRollup was empty at read time. The six expected workflow checks (Skills, manifests, and Bash installer, Windows test shard (windows-1..4), PowerShell installer) had not been reported yet. Under the reporting contract they count as missing: 0 passed, 0 pending, 6 missing. There was no polling and no CI fix round.

Residual risk

  • The credential guard after an unresolved directory change is a static, name-based best effort. It does not catch an operand that is itself a variable or substitution (cat "$F"), or a directory-wide operand such as . inside a store directory. External isolation still denies the stores.
  • Some reads that were already uninspected at 5b6ff3a remain so: recursive reads of a store's parent when the directory is known (cp -r ~/.codex …), extglob, and a CDPATH that is set in a profile but not exported.
  • Interpreter, eval and $(…) internals are opaque to the hook, as before.

…s, track HOME/OLDPWD (#439)

Post-change review of the REV-006/REV-008 fixes:
- After an unresolved directory change, a bare wildcard, brace, `config`
  or `hosts.yml` is guarded only standing alone or below a store-like
  parent; key-like names stay guarded at any depth; `sso`/`cli` count only
  before `cache`. `source venv/bin/activate && pytest tests/cli/x.py` and
  `eval ... && rm -rf build/*` ask again instead of being refused.
- `env` short-option clusters, unique `--chdir` prefixes and a `-C` inside
  an `-S` value are recognised.
- A reassigned HOME makes bare `cd`/`~` targets unresolved; a reassigned
  OLDPWD makes `cd -` unresolved.

[REV-005] · low · resolved · valid · blocks:no — The "Codex" AC-8 parity test does not exercise Codex

Confirmed by the rereview. The native checks are still frozen and unverified.

[REV-006] · medium · resolved · valid · blocks:yes — A relative argument after cd "$VAR" is refused with no consent question, even when it is not a path

The fix is in 496c6fc. This attempt re-ran the rereview's reproductions through test_rev006_*: cd "$X" && echo done, cd "$REPO_ROOT" && make test and cd "$(git rev-parse --show-toplevel)" && pytest tests ask, and run after consent. cd "$X" && cat auth.json is still guarded.

The post-change review found that the fix added new refusals with no question after source/eval. For example, source .venv/bin/activate && pytest tests/cli/test_main.py and eval "$(pyenv init -)" && rm -rf build/* were refused, which is a toolkit veto. b15056e narrows the name check in _could_name_credential:

  • A key-like last part is still guarded at any depth. That covers id_rsa, *.pem, and a glob with at least two literal characters that may match one, such as keys/*rsa.
  • A bare wildcard, a brace, config or hosts.yml is guarded only when it stands alone, or when its parent may name a store directory or cache (.s?h/*, cache/*).
  • sso/cli count only when followed by cache.

build/*, tests/cli/x.py, src/* and .github/workflows/*.yml now ask. They are covered by test_unresolved_directory_asks_for_project_paths_below_it in resolve and rereview.

[REV-007] · low · resolved · valid · blocks:no — Glob credential matching lets * cross /, so unrelated absolute globs count as credential reads

The fix is in 496c6fc. test_rev007_* passes at the new head: ls <users>/*/project, ls ~/* and du -sh /h* ask, and ls ~/.* and cat ~/.s[^x]h/id_rsa are still guarded. Nothing changed in this attempt.

[REV-008] · medium · resolved · valid · blocks:yes — builtin cd, command cd and CDPATH still get past the segment credential guard

The fix is in 496c6fc, and test_rev008_builtin_command_and_cdpath_directory_changes_are_guarded passes. The post-change review found more directory-change spellings that got past the guard. b15056e closes them in _env_chdir and _compound_analysis, and test_rev008_env_options_and_reassigned_home_or_oldpwd_are_guarded covers them:

  • env now parses short-option clusters the way env does. In -uLC_ALL -C "$X", the value of -u, -S or -a is no longer read as -C.
  • Any unique long prefix of --chdir counts, including --c=.
  • A -C/--chdir inside an env -S/--split-string value is an unresolved directory change, as in env "-S-C $X" cat id_rsa.
  • When the source names HOME other than as an expansion (HOME=, read HOME, printf -v HOME), a bare cd, cd ~ or cd $HOME is unresolved. When it names OLDPWD, cd - is unresolved.

Post-change review and security

  • Delta base. The trusted rereview receipt names 5b6ff3aa57253d86f22b960ee8f1b2d0f9a7b7b6, which is an ancestor of the new head. The delegated cc-code-review passes reviewed 5b6ff3a..496c6fc, then this attempt's own changes.
  • First pass, over 5b6ff3a..496c6fc.
    • It reported one P1: . or .. after an unresolved cd reaches the consent question.
    • It also reported three P2s: env --c=/-uX -C, HOME/OLDPWD, and the new source/eval vetoes.
    • I downgraded the P1 to a residual. The operation is asked with the unresolved-directory warning, never allowed silently. Refusing . would veto pytest ., git add . and ls . after any source or cd "$X", which is the REV-006 class. External isolation still denies the stores. The docs and the PA-28 row now say so.
    • The three P2s are fixed.
  • Second pass, over this attempt's diff.
    • It reported one P1: env "-S-C $X" had regressed relative to 496c6fc. It is fixed.
    • It reported one P2 (read HOME/printf -v HOME) and two P3s (keys/*rsa, cache/*). All three are fixed.
    • A remaining P3 is documented, not fixed: build/*/* after an unresolved directory is still refused, because */* may reach ~/.config/gh/hosts.yml.
  • Third pass.
    • It confirmed the four fixes and found no P0 or P1. cat src/*.ts and ls build/*.json ask.
    • It reported two P2s, both fixed. env also splits an -S value on \_, so any -…C or --c in the value now counts. A HOME built from quotes (declare "HO""ME=$X") is caught because the assigning builtins (declare, export, read, printf, …) make a bare cd or ~ target unresolved.
    • It reported a P3, also fixed: build/cache/* was refused. Now only a leading cache/ counts.
    • Two P3s remain and are documented: unusual globs such as lib/*ts that match a key name, and build/*/*.
  • Security. The deterministic security_review.always_when rule did not fire, and the plan has security_required: false. The change touches the credential guard, so the delegated passes reviewed it for credential-read bypasses as a security concern.

GitHub confirmed the head b15056e2bb32091c3b9ebb1b9c2fd698a77a5f30 right after the push.

  • Its statusCheckRollup was empty, so the workflow checks had not been registered yet. Counts: 0 passed, 0 failed, 0 pending.
  • The expected workflow checks (Skills, manifests, and Bash installer, Windows test shard (windows-1..4), PowerShell installer) are neither passed nor failed.
  • There was no polling and no CI fix round. The cycle's CI gate decides.

Residual risk

  • The credential guard after an unresolved directory change is a static, name-based best effort. The following get the consent question with a warning rather than a refusal: an operand that is a variable or substitution, a directory-wide operand (.), a store subdirectory named on its own (sso), and a key name inside a brace at depth. External isolation still denies the stores.
  • A subcommand word spelled like a store file, such as config in git config, is still refused after an unresolved directory change. So are build/*/* and unusual key-like globs such as lib/*ts. Use an explicit absolute directory.
  • Interpreter, eval and $(…) internals are opaque to the hook, as before.

[CCR-20261109-003] · senior_reviewer · anthropic/claude-opus-5-5→? · high · schema:2

Verdict: CHANGES_REQUESTED on head b15056e2bb32091c3b9ebb1b9c2fd698a77a5f30 (previous review: 5b6ff3aa57253d86f22b960ee8f1b2d0f9a7b7b6). Blocking finding: REV-009.

What changed since the previous review

5b6ff3a..b15056e has 2 commits (496c6fc, b15056e) touching 6 files (+625/−98). They move the compound guard into _compound_analysis. An unresolved directory (variables, CDPATH, a reassigned HOME/OLDPWD, eval/source/trap/alias) now refuses only operands that may name a credential store, and asks for every other operand with a warning. The commits also track builtin/command cd/pushd/popd and env -C/--chdir (combined short options, abbreviations, -S values), and match globs one component at a time. The docs (host-permissions.md and the PA-28 row) were updated to match. I re-read the full accumulated diff (origin/main...b15056e, merge base eaadf5494b4c3c4c4acd25e72f34fc4950c1e5fa, 2745 lines, as supplied by the runtime), with the focus on this delta.

Previous findings

[REV-001] · high · resolved · valid · blocks:yes — Regex grants match raw compound shell source, so a simple-command pattern authorizes other segments

Still resolved. test_rev001_* passes at this head.

[REV-002] · medium · resolved · valid · blocks:yes — The segment credential guard compares literal paths, so cd options, pushd and globs get past it

Still resolved. Every test_rev002_* case passes at this head.

[REV-003] · medium · resolved · valid · blocks:no — Every consent question names the configured test command, even for unrelated commands

Still resolved.

[REV-004] · medium · resolved · valid · blocks:no — An invalid edited pattern, or forever for review, ends the whole cycle instead of asking again

Still resolved. test_rev004_* and the 6 characterization tests pass.

[REV-005] · low · resolved · valid · blocks:no — The "Codex" AC-8 parity test does not exercise Codex

Still resolved. The native PA-19 checks remain frozen and unverified (see Verification).

[REV-006] · medium · resolved · valid · blocks:yes — A relative argument after cd "$VAR" is refused with no consent question, even when it is not a path

Verified by running test_rev006_unresolved_directory_asks_for_non_credential_operands (in resolve and rereview). The three reproductions from my previous review now ask and run after consent: cd "$X" && echo done, cd "$REPO_ROOT" && make test, and cd "$(git rev-parse --show-toplevel)" && pytest tests. The question carries the unresolved-directory warning and stays within 600 characters. test_unresolved_directory_asks_for_project_paths_below_it passed too: source …/activate && pytest tests/cli/… and eval "$(pyenv init -)" && rm -rf build/* ask. The credential-name forms (cat auth.json, cat id_rsa, cat *, cat keys/*rsa, cat cache/*, …) stay guarded. What remains refused is documented in PA-28 and host-permissions.md: a subcommand word spelled like a store file (git config), build/*/*, and unusual key-like globs. This is the "refuse only names that may be a store" rule the previous review proposed, so I accept it as a disclosed residual.

[REV-007] · low · resolved · valid · blocks:no — Glob credential matching lets * cross /, so unrelated absolute globs count as credential reads

Verified by running test_rev007_globs_match_one_component_at_a_time. ls <users>/*/project, ls ~/*, du -sh /h*, find … -path "<users>/*/x" and ls ~/*/notes reach the question and run after consent. ls ~/.*, cat ~/.s[^x]h/id_rsa, brace and ** spellings, and dotglob/BASHOPTS stay guarded. _reaches is iterative and bounded by the product of the pattern and store lengths. The 990-level ** test finishes in well under its 10 s bound.

[REV-008] · medium · resolved · valid · blocks:yes — builtin cd, command cd and CDPATH still get past the segment credential guard

Verified by running test_rev008_builtin_command_and_cdpath_directory_changes_are_guarded and test_rev008_env_options_and_reassigned_home_or_oldpwd_are_guarded. Every form from my previous review is now refused even with an approved grant: builtin cd, command [-p|--] cd, builtin pushd, CDPATH=~ cd, export CDPATH, and an inherited CDPATH. So are eval, source and trap loaders, the env -C/--chdir/--chd/-vC/-iC…/-S spellings, and a reassigned HOME/OLDPWD. command -v cd and env -C /outside/api still run after consent. The same class remains open through two spellings this fix does not model; they are reported below as REV-009 and REV-010.

New findings

[REV-009] · medium · open · - · blocks:yes — Tilde prefixes ~user, ~+ and ~- are expanded as ~, so the credential guard checks the wrong path

Path: scripts/stage_permissions.py L628 (_shell_segments, added by this PR).

_parse_simple refuses a ~ at the start of a word, so such a command falls back to _shell_segments. That function replaces only the ~ character with os.path.expanduser("~") and keeps the rest of the tilde prefix as literal text. The guard therefore sees a different path from the one bash reads:

  • cat ~datacas/.ssh/id_rsa: the guard checks /home/datacasdatacas/.ssh/id_rsa, while bash reads /home/datacas/.ssh/id_rsa. This is a single segment and needs no cd.
  • cd ~ && cat ~+/.ssh/id_rsa: the guard checks /home/datacas+/.ssh/id_rsa, while bash reads $PWD/.ssh/id_rsa, which is ~/.ssh/id_rsa.
  • cat ~-/…: bash reads from $OLDPWD. After an unresolved cd, cd "$X" && cat ~+/id_rsa also gets past _could_name_credential, because the mis-expanded operand is absolute and that function skips absolute operands.

The mis-expanded path is absolute and names no store, so protected_reason returns None for all of these. The operation then gets the ordinary shell-consent question with no mention of the guard, and an approved compound: true pattern that matches it authorizes it. AC-10 says such a pattern "grants nothing for it and the question says so". credential_reason itself would handle ~user correctly (os.path.expanduser("~user/…")), but the parser has already destroyed the prefix. This is the same class as REV-002 and REV-008. Claude's sandbox read denials and the Codex profile still deny ~/.ssh wherever they are active.

I traced this by reading the code; it was not executed. The probe python3 -I -c "…parse_command('cat ~datacas/.ssh/id_rsa')…" was refused by this stage's command table (command_bafb56cbbf2c222d54ff948d4a3861407070c4ffdc938938cdd26eaf95e23678, accessory). I did not try to get around the refusal.

Fix: expand only a bare ~ or ~/… at the start of a word, and pass ~user through to credential_reason's expanduser. Treat ~+ as the segment's possible working directories, and treat ~-/~N/~+N/~-N as unresolved, with the same name check _could_name_credential applies. Add regressions for cat ~$USER/.ssh/id_rsa, cd ~ && cat ~+/.ssh/id_rsa and cd ~/x; cd /tmp; cat ~-/../.ssh/id_rsa.

[REV-010] · low · open · - · blocks:no — The env -C guard applies only when env is the program word, so command env -C "$X" and wrapped forms get past it

Path: scripts/stage_permissions.py L3624 (protected_reason).

_env_chdir runs only when os.path.basename(words[0]) is env. The following forms change the directory just as env -C does, but the guard sees command, nice or timeout as the program and checks id_rsa against the clone:

  • command env -C "$X" cat id_rsa
  • nice env -C "$X" cat id_rsa
  • timeout 5 env -C "$X" cat id_rsa

command is the wrapper that REV-008 unwraps for cd. With a literal store directory (… env -C ~/.ssh …), the directory operand is already caught directly, so only the unresolved form is affected. Wrapping a program in a runner is close to the documented interpreter opacity, so this is non-blocking. Traced, not executed.

Fix: apply _unwrapped_builtin before the env check, and either strip the common no-argument runners (nice, timeout N, stdbuf …, nohup) or apply _could_name_credential to any segment that contains an env word followed by -C/--c…. Add regressions.

Security triage and audit

  • The deterministic rule did not fire. .code-cycle.yml declares no security_review.always_when, and no changed path matches the mandatory minimum (CI, secrets, agent configuration).
  • Triage and the runtime plan (security_required: true) both require the audit. The delta rewrites the credential guard and the compound-command analysis.
  • cc-security-review ran as a delegated pass on head b15056e, over the fix delta and the parser code it depends on. It found REV-009 and REV-010.
  • Reviewed with no finding:
    • per-component glob matching (_part_matches, _reaches, _BRACKET), including dotfile rules, **, and .. after an expanded part or inside braces;
    • the literal treatment of glob characters in the working directory;
    • _env_chdir short-option clusters, long-option prefixes, and -S splitting;
    • the HOME/OLDPWD reassignment heuristics, which only over-ask;
    • the fail-closed except Exception in protected_reason;
    • the unresolved_directory flag on the refusal request and its question text.
  • The guard never reads the credential paths.

Unverified

  • REV-009 and REV-010 were traced from the code at this head and not executed (see the refused probe above).
  • I could not read the failed Windows shard's log: gh run view 42677190477 --job 129361630834 --log-failed was refused by the stage table (command_741119e5485bcf18b35f7d6258818fe8b6da3fa202b52a1efbb7489c8a539c5a, accessory).

CI (parallel policy, read once)

Check State
Skills, manifests, and Bash installer pass
Windows test shard (windows-1) pass
Windows test shard (windows-2) pass
Windows test shard (windows-3) fail
Windows test shard (windows-4) pending

3 passed, 1 failed, 1 pending. The local Linux suite passes at this head, so the windows-3 failure is specific to Windows or to the CI environment. The cycle's CI gate decides on it.

Residual risk

  • The credential guard after an unresolved directory is a static, name-based best effort. Interpreter, eval and $(…) internals stay opaque, and only external isolation constrains them.
  • Toolkit refusals that remain, disclosed in PA-28: git config and similar subcommand words, build/*/*, and key-like globs after an unresolved directory.
  • An approved compound: true regex authorizes every segment of matching source. Only the regex and the per-segment guards limit it, so REV-009 matters for that path.

… runners, make consent tests portable (#439)

REV-009: the shell parser expanded only the `~` of `~user`, `~+` and `~-`,
so the credential guard checked a path bash never reads. A bare `~` still
names $HOME; `~user` keeps its prefix for expanduser, `~+` resolves to the
segment's working directory, and `~-`, `~N`, `~+N`, `~-N` (and `~+` after a
possible PWD assignment) count as an unresolved directory with the store-name
check.

REV-010: `env -C`/`--chdir` is detected at any `env` word, so `command env`,
`nice env`, `timeout 5 env` and similar runners keep the guard.

CI (windows-3): test_consent_variants read UTF-8 docs with the platform
default encoding, which fails under cp1252, and its bash, symlink and
POSIX-path cases cannot run on Windows. Read the docs as UTF-8 and mark the
POSIX shell cases as skipped on Windows; the Linux job runs them.
…ns, tighten env runner detection (#439)

The post-fix review found that keeping `~` literal before a brace let
`cat ~{,}/.ssh/id_rsa` past the guard, since bash expands braces before the
tilde. A `~` followed by `{` expands to $HOME again, so the brace part may
name any home entry.

The shell parser now removes backslash-newline continuations and decodes
ANSI-C `$'…'` and locale `$"…"` quoting, so `cat ~/.s\<newline>sh/id_rsa` and
`cat $'/home/u/.s\x73h/id_rsa'` reach the credential guard as the path bash
reads.

`env -C` is detected only behind runner words (`command`, `nice`,
`timeout 5`, options, assignments), so `echo env -C "$X" id_rsa` and
`grep env -C "$N" config` are no longer refused.
…pansions, fail-closed env runners (#439)

The security pass on the previous fix found:

- The runner allowlist for `env -C` failed open on runner option values
  (`timeout -s KILL 5 env -C ~ cat .codex/auth.json`, `stdbuf -o L`,
  `sudo -u root`, `xargs`, `exec -a`). Any `env` word counts again; only
  programs that just print or search their arguments (`echo`, `printf`,
  `grep`, `rg`) are exempt, which keeps `echo env -C "$X" id_rsa` askable.
- Python's unicode_escape differs from bash: `\u2f` (1-4 hex digits),
  `\c@` (NUL) and NUL truncation hid store paths, and a decoded NUL made
  `read -d $'\0'` an ungrantable refusal. `_ansi_c` now decodes `$'…'`
  exactly as bash does and stops at the first NUL.
- A continuation between `$` and its quote, name or brace (`$\<nl>'…'`,
  `$HO\<nl>ME`) skipped decoding. `_splice_dollar` removes continuations
  inside a `$` expansion using the tokenizer's own quote state.

Status: RESOLVED on head d73396836f2f41241d5a8b94b8e5402c97ae71b8 (previous head b15056e2bb32091c3b9ebb1b9c2fd698a77a5f30). No finding remains open. The failed required check of b15056e was diagnosed and fixed in this change (see CI failure on the judged head). Verification is not_verified only because the two native parity checks cannot run from a resolve stage.

Both open findings were triaged against b15056e before any edit. Both are valid.

Unchanged: still resolved.

[REV-009] · medium · resolved · valid · blocks:yes — Tilde prefixes ~user, ~+ and ~- are expanded as ~, so the credential guard checks the wrong path

Paths: scripts/stage_permissions.py (_shell_segments, _tilde_directory, _could_name_credential, _compound_analysis, credential_reason). Fix commit: 9ad0e26; hardened in 0079aef.

What changed:

  • The parser expands only a bare ~ (followed by /, a separator, { or the end of the source) to $HOME. Every other prefix keeps its text.
  • ~user/… resolves through os.path.expanduser, so it names that user's home directory, as bash does.
  • ~+/… resolves against each possible working directory of the segment.
  • ~-, ~N, ~+N and ~-N count as an unresolved directory, and so does ~+ when the source may assign PWD. These forms keep the store-name check and the question warning, on operands, redirect targets, cd/pushd targets and env -C values.

Verified by running test_rev009_tilde_prefixes_name_what_bash_reads in resolve and rereview:

  • On the pre-fix source (b15056e), every reproduction from the rereview failed: cat ~datacas/.ssh/id_rsa, cd ~ && cat ~+/.ssh/id_rsa, cd ~/x; cd /tmp; cat ~-/../.ssh/id_rsa, cd "$X" && cat ~+/id_rsa, and more.
  • At d733968, all of them are refused even with an approved grant.
  • cat ~+/README.md, cat ~-/notes.txt, cd ~-; ls and ls ~<user>/projects still reach the consent question. The ~- forms carry the unresolved-directory warning.

One adjustment to the reviewer's suggested regression: cat ~$USER/… reads a relative ~<name> path in bash, because tilde expansion runs before parameter expansion. The test uses the real login name instead.

[REV-010] · low · resolved · valid · blocks:no — The env -C guard applies only when env is the program word, so command env -C "$X" and wrapped forms get past it

Path: scripts/stage_permissions.py (protected_reason). Fix commits: 9ad0e26 and b0716d7.

What changed: any env word in a segment now starts the env -C/--chdir analysis. The only exception is a program that just prints or searches its arguments (echo, printf, grep, egrep, fgrep, rg).

Verified by running test_rev010_env_chdir_behind_command_and_runners_is_guarded:

  • The rereview's reproductions are now refused: command env -C "$X", nice env -C "$X" and timeout 5 env -C "$X".
  • So are the forms the security pass added: timeout -s KILL 5 env -C ~ cat .codex/auth.json, stdbuf -o L, sudo -u root, xargs -a … and exec -a name.
  • echo env -C "$X" id_rsa and grep env -C "$N" config still ask.

Post-change review (delegated, fix delta b15056e..HEAD)

b15056e is an ancestor of the new head, so this pass reviewed the fix delta. Two delegated passes ran: cc-code-review combined with security on 9ad0e26, then cc-security-review on 9ad0e26..26f5855. Every P1 they confirmed is fixed in this change, each with a regression test that fails on the source it was found in:

  • Brace bypass (introduced by 9ad0e26, fixed in 0079aef). Keeping ~ literal before a brace let cat ~{,}/.ssh/id_rsa past the guard, because bash expands braces before the tilde. A ~ followed by { expands to $HOME again.
  • Quoting and continuations hid store paths (present since the parser was added by this PR, fixed in 0079aef and b0716d7). $'…', $"…" and backslash-newline did not reach the guard decoded: cat $'/home/u/.s\x73h/id_rsa', cat ~/.s\ newline sh/id_rsa, $\ newline '…' and $HO\ newline ME.
    • _ansi_c now decodes $'…' exactly as bash does: octal, \x, \u with 1–4 digits, \U, and \cX, ending at the first NUL.
    • _splice_dollar removes continuations inside a $ expansion, using the tokenizer's own quote state.
  • Runner allowlist failed open (introduced by 0079aef, fixed in b0716d7). It is replaced by the fail-closed rule described under REV-010.
  • NUL over-refusal (introduced by 0079aef, fixed in b0716d7). A decoded NUL made read -d $'\0' an ungrantable refusal. The idiom now asks normally.

CI failure on the judged head (b15056e, run 42677190477)

  • Check run 129368188855, "PowerShell installer": failed. Its step "Require all Windows test shards to pass" fails whenever a shard fails, and job 129361630834, "Windows test shard (windows-3)", failed.
  • The failure logs could not be read. gh run view 42677190477 --repo datacas/code-cycle-toolkit --job 129368188855 --log-failed was refused by the stage sandbox's network filter for results-receiver.actions.githubusercontent.com. A retry got the same refusal. The annotations only say Process completed with exit code 1.
  • Diagnosis, from the code (not from the log).
    • windows-3 failed on all four heads of this branch, while main at merge base eaadf54 passed.
    • The only module this PR adds to that shard is tests/test_consent_variants.py.
    • One cause is certain: test_ac12_documentation_contract calls read_text() with no encoding. On Windows that decodes with cp1252, and the docs contain bytes cp1252 cannot decode: Í (C3 8D) and ← (E2 86 90).
    • The module also runs bash -c baselines and creates symlinks. It also embeds ~, /-rooted and host paths in shell source, and a Windows host path's backslashes are shell escapes there. The repository already skips bash-running tests on Windows.
  • Fix (9ad0e26).
    • The docs are now read as UTF-8.
    • The POSIX shell cases are marked posix_shell, which skips them on Windows. The Linux job (python3 -m unittest discover -s tests -v) still runs all of them.
    • Platform-neutral cases still run on Windows: grant validation, questions, retries, layer labels and the docs contract.
  • Not yet confirmed. Whether windows-3 passes at d733968 is unknown until CI runs. If it still fails, its log is needed to find the remaining cause.

native-codex-parity (required, AC-8) native Codex PA-19 parity unverified: same reason, plus the nested Codex socket limitation

The conclusion is not_verified (tests.version=2). AC-8 stays open, and #455 stays open.

The local run shares Linux, Python 3 and bash with the self-hosted Linux CI job. It does not share Windows, the cp1252 code page or the Windows shard runner.

Accessory operations the stage table refused (none were essential):

  • gh api repos/…/actions/jobs/129368188855
  • git archive and git stash, which I wanted for side-by-side reproduction. I used git checkout <sha> -- scripts/stage_permissions.py and then restored from HEAD.
  • python3 -W error::DeprecationWarning …. The test asserts the same thing with warnings.simplefilter("error").

Security

  • The plan sets security_required: true, and the fix touches the credential guard, so the audit ran.
  • The deterministic minimum did not fire: no CI, secret or agent-configuration path changed.
  • cc-security-review ran as delegated passes over the fix delta. Its confirmed P1s are fixed above.

Documentation

  • docs/host-permissions.md describes tilde prefixes, env -C behind runners, and the decoded quoting and continuations.
  • docs/capability-parity-audit.md row PA-28 is updated to match.
  • docs/ROADMAP_V2.md needs no change: no issue or milestone changed.

CI of the pushed head (parallel policy, read once)

gh pr view 468 --json headRefOid,statusCheckRollup returned head d733968 with no check registered yet. The six expected jobs of "Validate package" are all pending:

  • Skills, manifests, and Bash installer
  • Windows test shard (windows-1)
  • Windows test shard (windows-2)
  • Windows test shard (windows-3)
  • Windows test shard (windows-4)
  • PowerShell installer

Residual risk

  • Pre-existing, outside this change; reported, not fixed:
    • A bare assignment segment (X=1; make) is still refused with "an environment prefix needs a command". This is a possible toolkit veto with no PA row.
    • Other programs that change directory (tar -C, sudo -D, git -C, make -C) get no name check after an unknown directory.
    • A tilde after : in assignment-like arguments is not expanded.
  • Windows coverage of the guard's bash semantics is now established only by the Linux job.
  • The credential guard stays a static, name-based best effort. Interpreter, eval and variable internals depend on external isolation.

Verdict: CHANGES_REQUESTED on head d73396836f2f41241d5a8b94b8e5402c97ae71b8 (previous review: b15056e2bb32091c3b9ebb1b9c2fd698a77a5f30). Blocking findings: REV-011, REV-012.

What changed since the previous review

b15056e..d733968 has 6 commits (9ad0e26, 0079aef, 901c400, 26f5855, b0716d7, d733968) touching 4 files (+284/−18):

  • Tilde prefixes are now resolved the way bash reads them (~user, ~+, ~-, ~N).
  • env -C is detected behind any program word except echo/printf/grep/egrep/fgrep/rg.
  • The parser now decodes $'…' (ANSI-C) and $"…" quoting, and removes line continuations, also inside a $ expansion.
  • The POSIX shell tests are skipped on Windows (posix_shell), and the docs are read as UTF-8.
  • host-permissions.md and the PA-28 row were updated.

I read the whole fix delta and the guard code it depends on. The supplied accumulated diff (origin/main...d733968, merge base eaadf5494b4c3c4c4acd25e72f34fc4950c1e5fa) is 3011 lines, as the runtime stated.

Previous findings

[REV-001] · high · resolved · valid · blocks:yes — Regex grants match raw compound shell source, so a simple-command pattern authorizes other segments

Still resolved. test_rev001_* passes at this head.

[REV-002] · medium · resolved · valid · blocks:yes — The segment credential guard compares literal paths, so cd options, pushd and globs get past it

Still resolved. test_rev002_* passes at this head.

[REV-003] · medium · resolved · valid · blocks:no — Every consent question names the configured test command, even for unrelated commands

Still resolved.

[REV-004] · medium · resolved · valid · blocks:no — An invalid edited pattern, or forever for review, ends the whole cycle instead of asking again

Still resolved. test_rev004_* and the 6 characterization tests pass.

[REV-005] · low · resolved · valid · blocks:no — The "Codex" AC-8 parity test does not exercise Codex

Still resolved. The native PA-19 checks remain frozen and unverified (see Verification).

[REV-006] · medium · resolved · valid · blocks:yes — A relative argument after cd "$VAR" is refused with no consent question, even when it is not a path

Still resolved.

[REV-007] · low · resolved · valid · blocks:no — Glob credential matching lets * cross /, so unrelated absolute globs count as credential reads

Still resolved. REV-012 below is a separate gap in the same matcher.

[REV-008] · medium · resolved · valid · blocks:yes — builtin cd, command cd and CDPATH still get past the segment credential guard

Still resolved for the spellings it covers. REV-011 below covers the spellings that still get past it.

[REV-009] · medium · resolved · valid · blocks:yes — Tilde prefixes ~user, ~+ and ~- are expanded as ~, so the credential guard checks the wrong path

Verified by running test_rev009_tilde_prefixes_name_what_bash_reads (in resolve and rereview, inside test_consent_variants.py, 36 tests OK). It covers every reproduction from my previous review, all refused even with an approved grant: cat ~<login>/.ssh/id_rsa, cd ~ && cat ~+/.ssh/id_rsa, cd ~/x; cd /tmp; cat ~-/../.ssh/id_rsa, cd "$X" && cat ~+/id_rsa. The test also covers the brace forms ~{,}, ~{+,} and ~{a,}. Benign ~+/~- reads still ask.

From the code: _shell_segments expands only a bare ~ (or one before {). _tilde_directory is applied in credential_reason, _could_name_credential, the cd tracking and env -C. A brace alternative after an expanded ~ (for example ~{<login>,nobody}) becomes _ANY_PART in the matcher, so it still reaches the store.

The change to my suggested ~$USER regression is correct: bash runs tilde expansion before parameter expansion, so ~$USER stays literal.

[REV-010] · low · resolved · valid · blocks:no — The env -C guard applies only when env is the program word, so command env -C "$X" and wrapped forms get past it

Verified by running test_rev010_env_chdir_behind_command_and_runners_is_guarded. command, nice, timeout [-s KILL] N, stdbuf, sudo -u, xargs -a and exec -a in front of env -C are refused. echo env -C … and grep env -C … still ask. The fail-closed rule (any env word, except behind a print/search program) replaces the allowlist.

New findings

[REV-011] · medium · open · - · blocks:yes — CDPATH, HOME, OLDPWD, dotglob and GLOBIGNORE are detected in the raw source, so continuations and quoting the parser decodes hide them

Path: scripts/stage_permissions.py L3581–3596 (_compound_analysis, added by this PR).

The parser now removes backslash-newline, decodes $'…', and joins quoted pieces, as bash does. But _compound_analysis still decides from parsed.shell_source, the raw text, whether the source sets these variables or options. It uses substring and regex tests: "dotglob" in source, "GLOBIGNORE" in source, "CDPATH" in source, "OLDPWD" in source, and the HOME/PWD regexes. Bash sees the decoded name; the guard does not. Traced at this head:

  • shopt -s dot\ newline glob; cat ~/*/id_rsa. The parser yields shopt -s dotglob and cat <home>/*/id_rsa, but dotglob stays False. _part_matches("*", ".ssh", dotglob=False) returns False, so protected_reason returns None. With dotglob on, bash's ~/*/id_rsa matches ~/.ssh/id_rsa. The same happens with shopt -s "dot""glob" and shopt -s $'\x64otglob'.
  • CD\ newline PATH=~ cd .ssh; cat id_rsa. cdpath stays False, so the guard follows cd .ssh to <cwd>/.ssh, which names no store. Bash resolves .ssh through CDPATH=~ to ~/.ssh and then reads id_rsa. export "CD""PATH=~"; cd .ssh; cat id_rsa has the same effect without a continuation. The assigning_builtin fallback is applied to HOME/PWD only, not to CDPATH.
  • HO\ newline ME="$X" cd; cat id_rsa. home_assigned stays False (no HOME token, no assigning builtin), so the guard assumes cd goes to the real home. Bash goes to $X.
  • cd /tmp; export "OLD""PWD=$X"; cd -; cat id_rsa. oldpwd_assigned stays False, so the guard thinks cd - returns to the cwd before /tmp. Bash goes to $X.

Each of these reaches the ordinary shell-consent question with no guard notice, and an approved compound: true pattern that matches grants it. This contradicts AC-10, the same way REV-008 and REV-009 did. Claude's sandbox read denial and the Codex profile still deny ~/.ssh wherever they are active.

I traced this by reading the code; it was not executed. My probe python3 -I -c "…protected_reason(…)…" was refused by this stage's command table (command_61f1ec73ec9a87b5f8156200914d862ee3c9006cf15d7055d0ffc45f86be27b7, accessory). I did not try to get around the refusal.

Fix: derive these flags from the decoded segments instead of the raw source:

  • shopt/set arguments, assignment and export/declare/read/printf -v names, and environment prefixes, after continuation removal, $'…' decoding and quote joining.
  • Keep the conservative fallback (any assigning builtin, or a computed name such as declare "$n=…") for CDPATH, OLDPWD and GLOBIGNORE as well, not only for HOME/PWD.

Add regressions for the four spellings above.

[REV-012] · medium · open · - · blocks:yes — Glob options other than dotglob are not modelled, so nocaseglob lets a differently cased glob reach a store

Path: scripts/stage_permissions.py L3806–3819 (_part_matches) and L3527 (_environment_dotglob), added by this PR.

_part_matches uses fnmatch.fnmatchcase, and the only shell option it knows is dotglob/GLOBIGNORE. Take shopt -s nocaseglob; cat ~/.SS?/id_rsa: fnmatchcase(".ssh", ".SS?") is False, so credential_reason returns None. With nocaseglob on, bash matches ~/.ssh and reads the key. A nocaseglob inherited through BASHOPTS is not considered either.

shopt -s extglob with a pattern such as @(.ssh) is probably a second spelling: the part has no *?[, so _part_matches treats it as a literal that matches nothing. I did not confirm bash's dotfile handling for that form.

Impact and mitigation are the same as REV-011. Traced, not executed (same refused probe).

Fix: when the decoded source or BASHOPTS may enable nocaseglob, compare parts case-insensitively. When extglob may be on, treat a part that contains @(, +(, !(, *( or ?( as _ANY_PART. Alternatively, treat any shopt -s/set -o with an option outside a known-neutral list as making every glob part _ANY_PART. Add regressions.

Security triage and audit

  • The deterministic rule did not fire. .code-cycle.yml declares no security_review.always_when, and no changed path matches the mandatory minimum (CI, secrets, agent configuration).
  • Triage and the runtime plan (security_required: true) both require the audit, because the delta rewrites the shell parser and the credential guard.
  • cc-security-review ran as a delegated pass on head d733968, over the fix delta and the guard code it depends on. It found REV-011 and REV-012.
  • Reviewed with no finding:
    • _ansi_c: digit widths, \cX, and NUL truncation. A lone-surrogate \uD800 only reaches the fail-closed except path.
    • _splice_dollar: it is bounded by the 64 KiB source limit and does not run inside single quotes.
    • $"…" handling.
    • Bare-~ detection before /, separators and {. A continuation or quote after ~ leaves a literal ~ that expanduser still resolves.
    • Brace alternatives after ~.
    • _tilde_directory in every guard path.
    • The _ARGUMENT_READERS exemption: none of its programs can run env -C.
    • The posix_shell skips, which only remove Windows execution; the Linux job runs every case.
  • The guard never reads the credential paths.

Unverified

  • REV-011 and REV-012 were traced from the code at this head, not executed (refused probe above).
  • I could not read the failed windows-3 log: gh run view 42687504901 --repo datacas/code-cycle-toolkit --job 129398152254 --log-failed was refused by the stage table (command_d83127567473172059996a2885155384a6ac834769f120f509bbb75025ebdf51, accessory).

Check State
Skills, manifests, and Bash installer pass
Windows test shard (windows-1) pass
Windows test shard (windows-2) pass
Windows test shard (windows-3) fail (16m9s)
Windows test shard (windows-4) pass
PowerShell installer fail: it requires all Windows shards to pass

4 passed, 2 failed, 0 pending. windows-3 still fails after the UTF-8 and posix_shell changes, so the resolver's diagnosis did not remove the cause. The failure log is needed to find it. The cycle's CI gate decides on it.

Residual risk

  • The credential guard is a static, name-based best effort over bash semantics. Every shell feature that changes path or glob resolution needs its own model (REV-008 → REV-009 → REV-011/REV-012). Interpreter, eval and $(…) internals stay opaque, and only external isolation (Claude's sandbox, Codex's profile) constrains them.
  • Disclosed toolkit refusals that remain (PA-28): git config and similar subcommand words, build/*/*, and key-like globs after an unresolved directory. A bare assignment segment (X=1; make) is still refused with no PA row; the resolver reported this as pre-existing.
  • An approved compound: true regex authorizes every segment of matching source. Only the regex and the per-segment guards limit it.

[REV-011] · medium · resolved · valid · blocks:yes — CDPATH, HOME, OLDPWD, dotglob and GLOBIGNORE are detected in the raw source, so continuations and quoting the parser decodes hide them

Valid at the triaged head: raw-source flag detection missed decoded settings. Settings now come from decoded segment words, including environment prefixes, continuation removal, quote joining and ANSI-C decoding. Assigning builtins retain a conservative fallback for every path/glob setting, including computed names. Pre-fix reproduction: 20 failing subcases; final focused tests and real hook requests pass.

[REV-012] · medium · resolved · valid · blocks:yes — Glob options other than dotglob are not modelled, so nocaseglob lets a differently cased glob reach a store

Valid at the triaged head: nocaseglob and extglobs could bypass credential matching. Case-insensitive matching now follows decoded settings and inherited BASHOPTS; extglob components conservatively match one name. Extglob operands retain spaces and shell-looking separators, substitutions remain separately guarded, directory targets remain unresolved, and command-position !(...) retains its possible negated-subshell interpretation, including time -- and time -p --. Pre-fix reproduction: 18 failing subcases. Disposable Bash fixtures, protected and benign cases, and real hook subprocess checks pass.

Verification (agent-reported)

The complete suite passes: Ran 2552 tests in 820.388s, OK (skipped=1) (2,551 executed). The final focused suite passes 41 tests; characterization passes 6. Package validation passes, and BasedPyright reports 0 errors and 0 warnings. The real hook entry point passes 14 allowed/denied requests across resolve and rereview. The complete suite was repeated on the final commit after the first full run passed while final review fixes were landing. Test fixtures use disposable paths; no actual credential contents were read. Linux local execution is not Windows execution. No dependencies or type-check settings changed.

tests.version=2; frozen IDs, executor/profile identities, required controls and AC-n links are retained below. AC-8 remains open because both required native PA-19 parity checks remain unverified. Shared-hook grant metadata and Bash baselines do not substitute for native executor verification. #455 remains open.

Code and security review

The trusted delta base d73396836f2f41241d5a8b94b8e5402c97ae71b8 is an ancestor of the final commit; the delegated cc-code-review and cc-security-review read the full fix delta and relevant guard/parser paths. Both finished with no open findings after the extglob directory, operand-boundary and negated-subshell gaps they found were corrected and reprobed. security_audit_ran=true. Runtime security_required remained enabled. Mandatory path triggers did not fire, and the PR has no labels; authorization changes and the runtime plan required the audit independently.

Residual risks: static shell analysis remains conservative; broad extglob components and assigning builtins may retain guards for benign credential-like operands. Opaque interpreter/eval internals and dynamically constructed commands depend on external isolation. Native executor enforcement and Windows execution were outside these local passes.

Original failed checks — separate from review findings

On d73396836f2f41241d5a8b94b8e5402c97ae71b8, check run 129407234780 (PowerShell installer) failed at Require all Windows test shards to pass. gh run view --json jobs,headSha confirms Windows shard 3, job 129398152254, failed in Validate shard assignments and run tests; installer scenarios did not run. The supplied check annotation reports only exit code 1. Shard annotations and check output supply no test failure detail.

The prescribed gh run view 42687504901 --log-failed and job-specific variant were blocked by the sandbox domain allowlist at results-receiver.actions.githubusercontent.com. The read-only job-log API recovery was also blocked at productionresultssa13.blob.core.windows.net. No policy was widened or bypassed. The underlying shard failure remains undiagnosed: it is not claimed to be infrastructure, fixed, or superseded by resolving REV-011/REV-012. This essential CI diagnosis remains blocked by sandbox network access. environment_blocker is returned in the stage result with requires_human=false.

Publication and pushed-head CI (parallel policy)

Stage-sandbox publication preflight passed. The required publication helper uploaded 87067ba7258dbdbaa8b09747ea6e8d7ba4e80751, and gh confirmed that PR #468 points to that exact SHA before this receipt. Pushed-head checks were read once, without a CI wait or fix round: 0 passed, 0 observed failures, 5 pending, 1 expected check not yet reported. The structured failed/missing count is 1.

  • Skills, manifests, and Bash installer: pending
  • Windows test shard (windows-1): pending
  • Windows test shard (windows-2): pending
  • Windows test shard (windows-3): pending
  • Windows test shard (windows-4): pending
  • PowerShell installer: missing

Expected checks that are not yet emitted are listed as missing and included in the failed/missing count; they are not claimed to have executed or failed. In particular the dependent installer gate may appear only after its shard prerequisites finish. No remote CI outcome was substituted for local execution.

Owning documentation is updated in docs/host-permissions.md and PA-28 of docs/capability-parity-audit.md; the PR already documents #439/#455 in ROADMAP_V2. No issue was closed.

Verdict: CHANGES_REQUESTED on head 87067ba7258dbdbaa8b09747ea6e8d7ba4e80751 (previous review: d73396836f2f41241d5a8b94b8e5402c97ae71b8). Blocking finding: REV-013.

What changed since the previous review

d733968..87067ba has 1 commit (87067ba) touching 4 files (+264/−45):

  • _shell_settings derives CDPATH, HOME, OLDPWD, PWD, GLOBIGNORE, BASHOPTS, dotglob and nocaseglob from the decoded segment words, not the raw source. An assigning builtin sets all of them; a computed shopt/set option enables both glob modes.
  • nocaseglob (decoded or inherited through BASHOPTS) makes _part_matches compare without case.
  • The tokenizer now keeps an extglob (@(, +(, !(, *(, ?() as one word up to its matching ), except !( at command position. Extglob components match any name, and extglob cd/env -C targets are unresolved.
  • 4 new regression tests; host-permissions.md and the PA-28 row are updated.

I read the whole fix delta and the tokenizer and guard code it depends on. The supplied accumulated diff (origin/main...87067ba, merge base eaadf5494b4c3c4c4acd25e72f34fc4950c1e5fa) is 3230 lines, as the runtime stated.

Previous findings

[REV-001] · high · resolved · valid · blocks:yes — Regex grants match raw compound shell source, so a simple-command pattern authorizes other segments

Still resolved. test_consent_variants.py passes at this head.

[REV-002] · medium · resolved · valid · blocks:yes — The segment credential guard compares literal paths, so cd options, pushd and globs get past it

Still resolved.

[REV-003] · medium · resolved · valid · blocks:no — Every consent question names the configured test command, even for unrelated commands

Still resolved.

[REV-004] · medium · resolved · valid · blocks:no — An invalid edited pattern, or forever for review, ends the whole cycle instead of asking again

Still resolved. The 6 characterization tests pass.

[REV-005] · low · resolved · valid · blocks:no — The "Codex" AC-8 parity test does not exercise Codex

Still resolved. The native PA-19 checks remain frozen and unverified (see Verification).

[REV-006] · medium · resolved · valid · blocks:yes — A relative argument after cd "$VAR" is refused with no consent question, even when it is not a path

Still resolved.

[REV-007] · low · resolved · valid · blocks:no — Glob credential matching lets * cross /, so unrelated absolute globs count as credential reads

Still resolved.

[REV-008] · medium · resolved · valid · blocks:yes — builtin cd, command cd and CDPATH still get past the segment credential guard

Still resolved.

[REV-009] · medium · resolved · valid · blocks:yes — Tilde prefixes ~user, ~+ and ~- are expanded as ~, so the credential guard checks the wrong path

Still resolved.

[REV-010] · low · resolved · valid · blocks:no — The env -C guard applies only when env is the program word, so command env -C "$X" and wrapped forms get past it

Still resolved.

[REV-011] · medium · resolved · valid · blocks:yes — CDPATH, HOME, OLDPWD, dotglob and GLOBIGNORE are detected in the raw source, so continuations and quoting the parser decodes hide them

Verified by running test_rev011_decoded_settings_cannot_hide_credential_reads, which passes in resolve and rereview. It covers all four spellings from my previous review: the dot\-newline-glob continuation, "dot""glob", $'\x64otglob', CD\-newline-PATH=~, export "CD""PATH=~", HO\-newline-ME=, and export "OLD""PWD=$X". It also covers GLOBIGNORE, PWD and the computed names declare "$n=…", read "$n" and printf -v "$n". All of them are refused even with an approved .+ compound grant. Benign CDPATH/read/dotglob forms still ask and can be granted. test_rev011_rev012_bash_fixture_paths_reach_the_guard confirms with a real bash on disposable paths that each spelling reaches the fixture store. The code reads settings from parsed.segments, which include substitution bodies and environment prefixes.

[REV-012] · medium · resolved · valid · blocks:yes — Glob options other than dotglob are not modelled, so nocaseglob lets a differently cased glob reach a store

Verified by running test_rev012_glob_options_keep_credential_guards and test_rev012_extglob_directory_targets_remain_unresolved. They cover nocaseglob (plain, quoted, continued, ANSI-C, inherited BASHOPTS), extglob parts such as ~/@(.ssh|other)/id_rsa and ~/.s@(sh|foo bar)/id_rsa, and extglob cd targets. All of them are refused, and the benign /outside/api/*.JSON and @(schema|types).json forms can still be granted. REV-013 below is a new gap in the extglob tokenizer this fix added. It is not a reproduction of REV-012.

New findings

[REV-013] · medium · open · - · blocks:yes — The extglob tokenizer counts parentheses inside ${…} and $[…], so it folds the commands after an extglob into one operand

Path: scripts/stage_permissions.py L674–688 (_shell_segments), added by this commit.

Inside an extglob, the new branch counts every unquoted ( and ). Bash reads an extglob with parse_matched_pair, which skips a nested ${…} or $[…] as a whole, so parentheses inside them do not count. Escapes, quotes, $'…', $(…) and backticks are handled before this branch and agree with bash.

Example: ls @(${x:-(}) ; cat /home/<user>/.ssh/id_rsa /dev/null, with extglob on when bash parses that line. Bash reads the word @(${x:-(}), then runs cat … as its own command. The tokenizer counts the ( in ${x:-(}, so its depth never returns to 0. Unbalanced input is not rejected, so everything to the end becomes one ls operand: @(${x:-(}) ; cat /home/<user>/.ssh/id_rsa /dev/null. The cat segment is never analysed. credential_reason treats the operand as a path relative to the working directory (<cwd>/<any>/home/<user>/.ssh/…), which matches no store, and the key-name check applies only after an unresolved cd. The result is the ordinary shell-consent question, with no guard notice, and an approved compound grant allows it. This contradicts AC-10, like REV-011 and REV-012. A closing ) in a trailing # ) comment balances the toolkit's count, and bash ignores it.

How extglob gets turned on: by an earlier line of the same command (shopt -s extglob, newline, then the line above), because bash parses -c input one command at a time. It can also be inherited from the environment. The new bash fixture test itself runs with -O extglob. With extglob off, bash rejects the line and nothing runs.

Traced by reading the code; it was not executed. My probes were refused by this stage's command table: the PR's hook entry point on a JSON event (refused_7954a880792279f69edcbe1d5acb792121736e4e1242c1e19631dd3eca806cfd, input redirection) and a harmless bash -c baseline with echo in place of cat (refused_6101ece69623c01cc3a245277eeb341abab5d535f5d4dc311f19e473e27954cc). Both are accessory. I did not try to get around them. Claude's sandbox read denial and the Codex profile still deny ~/.ssh wherever they are active.

Fix, either:

  • skip a nested ${…} and $[…] inside an extglob as bash does, and refuse or fail closed when an extglob is still open at the end of the source; or
  • also analyse the text after the first ) that bash could treat as closing as separate segments, as is done for substitutions.

Add regressions for ${x:-(}, ${x/(/y} and $[(1)] inside @(, !( and *( (with and without a trailing # )), plus a bash fixture, with extglob set by an earlier line, showing that the hidden segment runs.

Security triage and audit

  • The deterministic rule did not fire. .code-cycle.yml declares no security_review.always_when, and no changed path matches the mandatory minimum (CI, secrets, agent configuration).
  • Triage and the runtime plan (security_required: true) both require the audit, because the delta rewrites the shell tokenizer and the credential guard.
  • cc-security-review ran as a delegated pass on head 87067ba over the fix delta and the tokenizer and guard paths it feeds. It found REV-013. Precondition: extglob on at parse time, plus consent to a compound command. Impact: a non-grantable credential read reaches an ordinary grantable question.
  • Reviewed with no finding:
    • _shell_settings: name matching on decoded words, assigning builtins (also through builtin/command), and computed shopt/set options.
    • _environment_nocaseglob and the case-insensitive _part_matches. Literal parts stay case-sensitive, as bash does without a glob character.
    • Extglob parts that match any name.
    • Extglob cd and env -C targets left unresolved.
    • The !( command-position exception after keywords, time -p -- and assignments.
    • Quote, escape, $'…', $(…) and backtick handling inside an extglob.

tests.version=2. The conclusion is not_verified, because the two required native parity checks did not run. AC-8 stays open, and #455 stays open. AC-10 is not met for the REV-013 spellings.

Unverified

  • REV-013 was traced from the code, not executed (refused probes above).
  • The resolver's diagnosis of the earlier windows-3 failure on d733968 remains open. The log could not be fetched, and that run is superseded by the new run below.

0 passed, 0 failed, 5 pending, 1 not yet reported. The cycle's CI gate decides on them.

Residual risk

  • The credential guard is a static, name-based approximation of bash. Each lexer or option feature needs its own model (REV-008 → REV-009 → REV-011/REV-012 → REV-013). Interpreter, eval and $(…) internals stay opaque, and only external isolation (Claude's sandbox, Codex's profile) constrains them.
  • Disclosed conservative refusals (PA-28): an assigning builtin or a computed shopt may keep the guard on a benign credential-like operand, and so may broad extglob components.
  • On a case-insensitive filesystem (macOS, /mnt/c), literal differently-cased store paths such as ~/.SSH/id_rsa are compared case-sensitively. This predates this commit, and I did not verify it here.

Status: BLOCKED pending diagnosis of the supplied CI failure, whose log cannot be fetched through this sandbox. REV-013 is fixed and locally verified. Native parity remains unverified; AC-8 and #455 stay open. No review approval is claimed.

Fix commit: d7ad729d79de33e4dc467acbe519a331f8716a0f. Only scripts/stage_permissions.py, tests/test_consent_variants.py and the owning docs/host-permissions.md page changed. Behaviour is documented in the same commit. The existing roadmap/audit treatment of #439/#455 remains applicable; neither issue was closed.

Findings

[REV-001] · high · resolved · valid · blocks:yes — Regex grants match raw compound shell source, so a simple-command pattern authorizes other segments

Carried forward from the trusted review; no new resolution claimed for this ID in this attempt.

[REV-002] · medium · resolved · valid · blocks:yes — The segment credential guard compares literal paths, so cd options, pushd and globs get past it

Carried forward from the trusted review; no new resolution claimed for this ID in this attempt.

[REV-003] · medium · resolved · valid · blocks:no — Every consent question names the configured test command, even for unrelated commands

Carried forward from the trusted review; no new resolution claimed for this ID in this attempt.

[REV-004] · medium · resolved · valid · blocks:no — An invalid edited pattern, or forever for review, ends the whole cycle instead of asking again

Carried forward from the trusted review; no new resolution claimed for this ID in this attempt.

[REV-005] · low · resolved · valid · blocks:no — The "Codex" AC-8 parity test does not exercise Codex

Carried forward from the trusted review; no new resolution claimed for this ID in this attempt.

[REV-006] · medium · resolved · valid · blocks:yes — A relative argument after cd "$VAR" is refused with no consent question, even when it is not a path

Carried forward from the trusted review; no new resolution claimed for this ID in this attempt.

[REV-007] · low · resolved · valid · blocks:no — Glob credential matching lets * cross /, so unrelated absolute globs count as credential reads

Carried forward from the trusted review; no new resolution claimed for this ID in this attempt.

[REV-008] · medium · resolved · valid · blocks:yes — builtin cd, command cd and CDPATH still get past the segment credential guard

Carried forward from the trusted review; no new resolution claimed for this ID in this attempt.

[REV-009] · medium · resolved · valid · blocks:yes — Tilde prefixes ~user, ~+ and ~- are expanded as ~, so the credential guard checks the wrong path

Carried forward from the trusted review; no new resolution claimed for this ID in this attempt.

[REV-010] · low · resolved · valid · blocks:no — The env -C guard applies only when env is the program word, so command env -C "$X" and wrapped forms get past it

Carried forward from the trusted review; no new resolution claimed for this ID in this attempt.

[REV-011] · medium · resolved · valid · blocks:yes — CDPATH, HOME, OLDPWD, dotglob and GLOBIGNORE are detected in the raw source, so continuations and quoting the parser decodes hide them

Carried forward from the trusted review; no new resolution claimed for this ID in this attempt.

[REV-012] · medium · resolved · valid · blocks:yes — Glob options other than dotglob are not modelled, so nocaseglob lets a differently cased glob reach a store

Carried forward from the trusted review; no new resolution claimed for this ID in this attempt.

[REV-013] · medium · resolved · valid · blocks:yes — The extglob tokenizer counts parentheses inside ${…} and $[…], so it folds the commands after an extglob into one operand

Fixed in d7ad729d79de33e4dc467acbe519a331f8716a0f. Nested parameter/arithmetic delimiters no longer change extglob depth; unterminated forms fail closed. Nested substitutions keep original quoting, ANSI-C escapes and continued dollar markers. Command comment boundaries use lexical word state; heredoc contents do not close a substitution. Five focused tests cover every extglob operator, both roles, trailing comments, protected substitutions, malformed input, resource bounds and a disposable Bash baseline. All 46 consent tests pass. Bash 5.1.16 confirms the arithmetic hidden-segment reproduction; parameter spellings differ on that version and retain conservative coverage.

Separate CI failure diagnosis

On the supplied head 87067ba7258dbdbaa8b09747ea6e8d7ba4e80751, check run 129450360242, workflow 42699763674, is PowerShell installer. Its failing step is Require all Windows test shards to pass. GitHub job metadata identifies the failed dependency as Windows test shard (windows-3), job 129441063701, step Validate shard assignments and run tests. Other three Windows shards and the Linux job passed. Both checks' annotations contain only exit code 1; the check output has no summary/text.

Requested full-run and per-job failure logs through gh run view --log-failed; the sandbox blocked results-receiver.actions.githubusercontent.com. Recovery through gh api repos/datacas/code-cycle-toolkit/actions/jobs/129450360242/logs was also blocked at productionresultssa13.blob.core.windows.net. All metadata/annotation reads used authenticated gh. The shard root cause remains undiagnosed; this is not evidence that infrastructure caused the CI failure. No speculative CI change was made. This obligation is separate from REV-013 and remains blocked by observed network isolation.

Post-change review and security audit

Trusted delta base 87067ba7258dbdbaa8b09747ea6e8d7ba4e80751 is an ancestor of the fix head; both delegated passes reviewed the complete fix delta, including current working changes, without an accumulated-diff fallback. The supplied accumulated diff was also inspected in sections: 3230 lines, SHA-256 eeb42d65ac0b589f3d467d51d1411ba743a3dbeb8119fecb0a4367f44dc3087f; large characterization records were compared structurally.

cc-code-review and mandatory cc-security-review completed with no remaining confirmed findings. Security review exercised disposable fake-Git reproductions for quoted delimiters, escaped ANSI-C quotes, continuations and escaped-space comments; intermediate issues were fixed before publication. Deterministic minimum did not fire (no CI, secret or agent-configuration path changed, no sensitive labels); permission-parser changes and runtime security_required: true independently require the audit. security_audit_ran=true.

Verification — cc-verify, agent-reported

Frozen check ID Result Evidence / limit
configured-test pass (exit 0) 2557 tests in 294.011s
issue-439-regression pass (exit 0) 46 tests in 7.024s
package-validation pass (exit 0) VALID: 16 skills (7 cycle, 9 supporting), shared sections in sync, cross-agent manifests aligned
type-check pass (exit 0) 0 errors, 0 warnings, 0 notes
native-claude-parity unverified The frozen identity supplies only an opaque command digest, without a runnable baseline binding. Shared-hook unit tests are not native executor evidence.
native-codex-parity unverified The frozen identity supplies only an opaque command digest, without a runnable baseline binding. Shared-hook unit tests are not native executor evidence. The known nested Codex socket mask also prohibits launching codex exec/sandbox here (docs/routing.md).
consent-characterization pass (exit 0) 6 tests in 10.007s

All frozen checks retain their runtime command, executor/profile, required status and stable AC-n links. tests.version=2, conclusion not_verified: required native parity checks did not execute. AC-1–AC-7 and AC-9–AC-12 have passing regression coverage; AC-8 remains open until both native baselines run. Shared-hook tests and disposable Bash fixtures are not native executor parity. No nested Codex or srt was launched.

The first full-suite attempt ran 2556 tests and failed only two new incorrect benign-consent expectations for slash-bearing brace operands, which retain the documented conservative PA-28 guard; those expectations were corrected. An intermediate full run passed 2556 tests; final-tree results above supersede it. Linux verification does not reproduce the Windows runner or prove the historical Windows shard cause. Tests use disposable paths and synthetic targets; no real credential contents were read. git diff --check passed.

Publication and CI

Publication preflight passed inside this stage's sandbox. The branch commit was uploaded using the runtime publication helper; gh pr view confirmed the PR head equals the uploaded commit before this receipt. CI policy is parallel: pushed-head checks were read once; no CI wait or fix round was run.

Head d7ad729d79de33e4dc467acbe519a331f8716a0f: 0 passed, 1 failed/cancelled/missing, 5 pending.

Check State
Skills, manifests, and Bash installer pending
Windows test shard (windows-1) pending
Windows test shard (windows-2) pending
Windows test shard (windows-3) pending
Windows test shard (windows-4) pending
PowerShell installer missing

An expected job that has not reported is listed as missing; dependency scheduling may create it later. No missing or pending job is counted as passed.

Residual limits

Static Bash analysis remains conservative and version-sensitive. Bash 5.3 current-environment substitutions and real native executor parity were not executed. External isolation remains required for opaque interpreter behaviour. The unresolved historical CI diagnosis is the stage blocker, separately recorded below.

Agent-reported verification — tests.version=2

Checks ran through rtk proxy, in the foreground, with output captured in the dispatch TMPDIR. Frozen command identities below are unchanged.

Status: CHANGES_REQUESTED on head b2efad715e02e08b471fd2106aa0699aaa5263b1. REV-013 is fixed and verified by execution. A new blocking finding, REV-014, is a pre-existing gap in the accumulated diff: a case statement inside a command substitution hides later commands from the segment guards.

Changes since the previous rereview (87067ba → b2efad7)

The accumulated diff (origin/main...b2efad7, 3460 lines, merge base f22fc1df8d07bce22be8ac519a60b89a3b5a8eb0) was confirmed and read per file. The parser, the segment guard loop (_compound_analysis) and protected_reason were re-read at this head.

[REV-013] · medium · resolved · valid · blocks:yes — The extglob tokenizer counts parentheses inside ${…} and $[…], so it folds the commands after an extglob into one operand

Verified by execution at b2efad7. test_rev013_nested_expansions_do_not_hide_later_segments passes for every operator × expansion × trailing-comment × role combination. So do …_expansion_substitutions_stay_guarded_and_safe_forms_get_consent, …_escaped_space_does_not_start_a_shell_comment, …_unterminated_extglobs_and_expansions_fail_closed, and the disposable-Bash baseline test_rev013_bash_fixture_executes_the_later_segment. That last test ran here and was not skipped: the issue-439 run reports 46 tests, OK, with no skips. The code at scripts/stage_permissions.py:736-743 and :555-663 matches the claim.

[REV-014] · medium · open · - · blocks:yes — A case pattern's ) inside $(…) ends the substitution early, so later commands are hidden from the segment guards

scripts/stage_permissions.py:555 (_shell_expansion_end), reached from _shell_segments at :746-760.

_shell_expansion_end counts parentheses in a $(…) body but does not model the shell grammar. A case pattern list closes with an unmatched ) (case a in a) …;; esac), and Bash 4 and later parse it as part of the substitution. The scanner returns at that ). Only case a in a is analysed as the substitution body. The outer scanner then treats the rest as ordinary text of the current word:

  • printf '%s' "$(case a in a) git push --force origin main ;; esac)": the remainder is still inside the outer double quote, so git push --force origin main ;; esac) becomes data of the printf word.
  • echo $(case a in a) git push --force origin main ;; esac): no separator comes before git, so git push --force origin main joins the echo segment's argument words.

In both forms parsed.segments has no segment whose program is git. _compound_analysis (:3748-3769) runs protected_reason once per segment, so _check_push never runs. A compound pattern grant such as the .+ grant the REV-013 tests use then covers the whole command. The same applies to a credential read: cat ~/.ssh/id_rsa in that position is hidden from credential_reason unless the working directory makes the outer word reach the store by chance. AC-10 says a pattern matching a protected command grants nothing for it and the question says so. AC-8 says each segment is analysed and guarded individually. Both are violated.

This gap predates the REV-013 commit, because the earlier inline paren counter had the same flaw. d7ad729 replaced that counter with _shell_expansion_end without adding case handling, so the gap remains in the accumulated diff. No case/esac handling or test exists (git grep for case/esac in the parser and consent tests returns nothing).

Evidence comes from a static trace of the current code. A runtime probe was not possible in this stage: bash and ad-hoc python3 are not in the rereview command table, and both refusals are recorded.

Suggested fix: fail closed. Treat a case keyword at command position inside a substitution body as unanalysable, which asks for interpreter consent with protected guards, or track case … in / ;; / esac so that pattern ) does not close the substitution. Add tests with Claude and Codex-shaped policies for the quoted and unquoted forms above, plus ;&/;;& and (a)-style patterns. Include a disposable-Bash baseline like test_rev013_bash_fixture_executes_the_later_segment.

Security triage and audit

The deterministic minimum did not fire: no CI, secret or agent-configuration path changed, and the PR has no labels. The runtime plan sets security_required: true, and the change is to the permission parser and pattern validation, so the cc-security-review pass ran on the delta and on the accumulated parser/guard surface for this head. Result:

  • Confirmed (static trace): REV-014 above. It bypasses a protected-command and credential guard under a compound grant or a consent answer.
  • Potential risk, not reproduced: in Bash POSIX mode (set -o posix or POSIXLY_CORRECT on an earlier line), single quotes inside a double-quoted ${x:-…} word are not quoting (Austin Group interp 221). _shell_expansion_end always treats them as quotes. Inside an extglob (:736) the folded text is appended as one operand without re-analysis, so @("${x:-'}") ; cmd ; echo "'}") could hide cmd in POSIX mode only. The $(…) path is not affected, because its body is re-split by _shell_segments, which treats those quotes as literal. This could not be reproduced (no bash in the stage table). The resolver should confirm it with the disposable-Bash fixture and, if it reproduces, fail closed on ' inside a double-quoted ${…} within an extglob, or on a posix setting.
  • grants.validate_pattern: the import change keeps every ReDoS/lookaround/backreference rejection unchanged and only swaps the module source. The importlib names are constants, so no import is attacker-controlled.

security_audit_ran=true.

Verification — agent-reported, tests.version=2

All checks ran in this stage's disposable clone at b2efad715e02e08b471fd2106aa0699aaa5263b1, in the foreground, with logs in the dispatch TMPDIR.

consent-characterization pass (exit 0) Ran 6 tests in 5.873s — OK

Conclusion: not_verified. Both required native parity checks (AC-8) did not run. AC-8 and AC-10 also stay open because of REV-014. The other criteria have passing regression coverage. The passing suite does not cover REV-014, because no test exercises case in a substitution.

Residual risk and verdict

The static Bash analysis is conservative but not a full shell grammar. Constructs that change how ) or quotes are read (case, POSIX-mode quoting, Bash 5.3 ${ …; } current-environment substitutions) need fail-closed handling or execution-backed tests. External sandbox isolation remains a required second layer. Verdict: CHANGES_REQUESTED (REV-014).

Refused accessory probes, recorded and not bypassed: bash --norc --noprofile $TMPDIR/report.md and python3 --version (rule command_table).

…#439)

A case pattern's closing ')' and the ';;', ';&' and ';;&' terminators no longer end a command or process substitution, so the commands of each clause reach the segment guards (REV-014). A case word in argument position stays data.

Status: CHANGES_REQUESTED on head 05d4cabec5515977348f2b9b25d853213b52cdc6. The REV-014 fix covers the forms reported and its tests pass. The same root cause still reproduces in positions where Bash recognises case that the new tracker does not model, so REV-014 stays open. No new finding ID: the remaining forms share the REV-014 root cause.

Changes since the previous rereview (b2efad7 → 05d4cab)

  • 05d4cab: REV-014 fix. _shell_expansion_end now tracks case clauses inside command and process substitutions (head → pattern → body). A pattern's ) (with or without the optional () and the ;;, ;& and ;;& terminators no longer end the substitution. A new _command_position decides whether case/esac is a reserved word. docs/host-permissions.md documents the rule. tests/test_consent_variants.py adds three REV-014 tests: 15 forms × Claude/Codex × resolve/rereview, argument-position case words, and a disposable-Bash baseline.

No resolver triage comment was published for REV-014, so its disposition stays -. The accumulated diff (origin/main...05d4cab, 3626 lines, merge base f22fc1df8d07bce22be8ac519a60b89a3b5a8eb0) was confirmed. The delta and the current _shell_expansion_end / _shell_segments were re-read in full.

scripts/stage_permissions.py:564-588 (_command_position, _COMMAND_PREFIX_WORD at :555) and :705-732 (_shell_expansion_end).

Fixed and verified: the 15 REV014_FORMS now produce a separate git push --force origin main segment. protected_reason names git and cat ~/.ssh/id_rsa is guarded, under the .+ compound grant, for Claude and Codex in both roles. The disposable-Bash baseline test_rev014_bash_fixture_runs_the_command_after_the_pattern ran and was not skipped (49 tests, OK, no skips).

Still reproducible (static trace). The tracker starts a case only where _command_position returns true. That covers the start of the list, after ;, &, | or a newline, after the last pattern ), after a non-extglob (, and after then|do|else|elif|if|while|until|time|!|{. Bash's reserved_word_acceptable (parse.y) accepts more positions, and the grammar lets case begin a valid command in several of them:

  1. After name(), as a function body. fname () compound-command is valid. In printf '%s' "$(f() case a in a) git push --force origin main ;; esac; f)", the last character before case is the ) of f(). That ) is not pattern_close, so _command_position returns False (:581-582). The case is never tracked, the pattern a) drops nesting to 0, and the substitution ends there. _shell_segments re-splits the body f() case a in a into [f] and [case, a, in, a]. The rest, git push --force origin main ;; esac; f), is data of the outer double-quoted printf word. No segment has program git, so _check_push never runs and the .+ compound grant covers the whole command. Bash defines f and calls it, which runs the push. The same happens with function f case a in a) … ;; esac; f (FUNCTION WORD is a reserved-word position) and with function f() case ….
  2. After time -p and time --. _COMMAND_PREFIX_WORD matches time only when it is the immediately preceding word, so "$(time -p case a in a) git push --force origin main ;; esac)" is missed. Bash accepts the reserved word after TIMEOPT/TIMEIGN.
  3. After coproc and coproc NAME. These are not in the list, so "$(coproc case a in a) git push --force origin main ;; esac)" is missed. The coprocess runs the command.
  4. Keywords split by a line continuation. _shell_keyword compares the raw source (source.startswith(word, i)), but Bash removes backslash-newline before it tokenises. "$(ca\⏎se a in a) git push --force origin main ;; esac)" is therefore not tracked. _shell_segments later decodes the body to case a in a, but the tail is already outside. The same applies to i\⏎n in the head, where the pattern ) then closes the substitution. REV-011 fixed this class for the environment detectors, but the new keyword tracker reintroduces it.

In every form a cat ~/.ssh/id_rsa in the same position is hidden from credential_reason in the same way. The unquoted echo $(…) variants fold the hidden words into the echo segment, as the original report describes. AC-8 (each segment analysed and guarded individually) and AC-10 (a pattern matching a protected command grants nothing for it) stay violated. git grep finds no coproc, () case, function … case or time -p case handling or test in the parser or the consent tests.

Evidence limit: static trace of the current code only. A runtime probe was not possible: bash and ad-hoc python3/new test files are not in the rereview command table or edit rule (earlier refusals recorded in the journal), and stage_permissions.py exposes only the stdin hook entry point.

Suggested fix: fail closed rather than enumerate. Over-recognising case is safe: the tracker then extends the substitution, the body is re-analysed, or it raises unterminated. Under-recognising it hides commands. One option is to model the full reserved_word_acceptable set: any ) and }, time followed by -p/--, coproc, coproc WORD, function WORD, plus done/fi/esac. Another is simpler: inside a substitution body, raise PolicyError (interpreter consent with the protected guards) for any unquoted case word the tracker did not open. In both cases, match keywords after removing line continuations. Add the four forms above to REV014_FORMS, so they run in the Claude/Codex × role matrix and in the Bash baseline.

Security triage and audit

The deterministic minimum did not fire: no CI, secret or agent-configuration path changed, and the PR has no labels. The runtime plan sets security_required: true, and the change is to the permission parser, so the cc-security-review pass ran on the delta and on the accumulated parser/guard surface at this head.

  • Confirmed (static trace), Medium: the residual REV-014 forms above. Precondition: a compound pattern grant, or a consent answer for the visible segments. Impact: a protected command (git push, credential-store read) runs without its guard and without the question naming it. Mitigation as suggested above.
  • Potential risk, not reproduced (carried over): in Bash POSIX mode, single quotes inside a double-quoted ${x:-…} within an extglob are not quoting, and _shell_expansion_end always treats them as quotes. Not affected by this delta.
  • Informational, not measured: _command_position slices and regex-searches the whole preceding body once per keyword step (:572-588). A long run of prefix keywords before a case costs O(n²) within the 64 KiB limit. That affects only the stage's own hook latency.
  • Aliases (shopt -s expand_aliases) are outside the parser model in general, not only for case. External sandbox isolation remains the second layer.

Retained trusted resolved state; this attempt makes no new resolution claim for this ID. Related regression coverage passes.

[REV-014] · medium · resolved · valid · blocks:yes — A case pattern's ) inside $(…) ends the substitution early, so later commands are hidden from the segment guards

Fixed in 48b3c0f501bb1fb47725238c82422bf476164949 (scripts/stage_permissions.py, tests/test_consent_variants.py; owning documentation in docs/host-permissions.md). Triage was frozen before source edits. Expanded tests reproduced hidden commands before the fix (49 tests, 51 failing subtests and 4 errors).

The substitution scanner now recognises function bodies, including Bash non-POSIX function names, coproc with an optional name, and time option prefixes. Keyword matching consumes line continuations while preserving original source offsets. Command-position analysis preserves escaped backslash pairs and a preceding case-pattern boundary through prefix stripping. It checks that a function header starts in command position, so empty extglob arguments remain data.

Regression coverage includes supported function/coprocess and continuation forms, nested cases after control prefixes, protected Git and fixture credential commands, ordinary consent for safe forms, argument-position negatives, and real hook subprocess allow/deny checks. Supported forms execute harmless markers in disposable Bash. This Bash rejects time -p case/time -- case; those have conservative parser coverage only. The matrix uses Claude/Codex grant metadata and resolve/rereview roles; it does not claim native executor parity.

Post-change review and security

Delegated cc-code-review reviewed the complete fix delta from trusted review base 05d4cabec5515977348f2b9b25d853213b52cdc6 (verified ancestor). It found no remaining P0–P3 findings after the targeted corrections. cc-security-review ran on the parser/consent trust boundary and fix delta: no confirmed vulnerability remains in the audited delta. security_audit_ran=true. Mandatory minimum paths did not change; the runtime requirement and permission-parser sensitivity require the audit independently.

The supplied accumulated diff was confirmed at 3626 lines and SHA-256 e5d081b19ebcbd1e9a900fdb32c8079ec1111490b93ee23295db723efc8ad713, and read in sections. The six large characterization snapshots were processed completely; their differences only insert refusal-layer fields. Trusted comment history recovered REV-001–REV-014 without gaps, collisions or recovery notes; no native review threads exist.

Verification — agent-reported, tests.version=2

All final local checks ran in the invoking checkout on the committed content. Full-suite tests, the regression suite, package validation, BasedPyright and characterization passed. The tests use disposable fixtures; local runs use the installed Python/Bash/tool versions, while Windows behavior remains a remote CI concern. Full check identities, AC-n links and output hashes follow. Earlier reproduction failures are retained as attempts; they do not replace final results.

Frozen check Result Evidence
configured-test pass (exit 0) Ran 2561 tests in 531.132s; OK (skipped=1)
issue-439-regression pass (exit 0) Ran 50 tests in 13.097s; OK
package-validation pass (exit 0) VALID: 16 skills (7 cycle, 9 supporting), shared sections in sync, cross-agent manifests aligned
type-check pass (exit 0) 0 errors, 0 warnings, 0 notes
native-claude-parity unverified The frozen command is an opaque digest with no runnable binding in this dispatch or repository; no native executor parity check ran.
native-codex-parity unverified The frozen command is an opaque digest with no runnable binding in this dispatch or repository; no native executor parity check ran. Nested Codex execution in this Codex sandbox is prohibited by the known socket-mask limitation (docs/routing.md).
consent-characterization pass (exit 0) Ran 6 tests in 22.046s; OK

Conclusion: not_verified because native-claude-parity and native-codex-parity did not run. AC-8 stays open for those required native checks. AC-1–AC-7 and AC-9–AC-12 have passing linked regression coverage. No requirement was removed or demoted. #455 stays open.

CI of the pushed head (read once, parallel policy)

Head 48b3c0f501bb1fb47725238c82422bf476164949: 0 passed, 1 failed-or-missing, 5 pending. The failure count includes expected gates not yet reported; a missing dependent job is not evidence that its execution failed. No CI wait or fix round was performed. These states are separate from local verification.

  • PowerShell installer: missing

Residual risks

The static parser is not the full Bash grammar. Dynamic interpreter behavior and unmodelled shell state still depend on external isolation. No native Claude/Codex parity or merge-readiness claim is made. The owning behavior is documented in docs/host-permissions.md; the existing #439/#455 roadmap and parity-audit updates remain in this PR.

Status: CHANGES_REQUESTED on head 48b3c0f501bb1fb47725238c82422bf476164949. The four REV-014 residual forms from the previous rereview are fixed and their tests pass. The same root cause still reproduces after for loop headers, so REV-014 stays open. No new finding ID: the remaining form has the same root cause.

Changes since the previous rereview (05d4cab → 48b3c0f)

  • scripts/stage_permissions.py: _COMMAND_PREFIX_WORD now accepts time -p/time --, coproc [NAME] and function NAME. A new _FUNCTION_HEADER lets a NAME() / function NAME() header give command position, as long as the header itself starts at command position. _shell_keyword returns a width and skips backslash-newline inside and after the keyword. _command_position removes continuations while keeping a map to the original offsets, so a pattern ) still matches after prefixes are stripped.
  • tests/test_consent_variants.py: 22 new REV014_FORMS entries and 3 REV014_TIME_FORMS entries, more argument-position negatives (echo function f case, echo @() case, …), and a real hook subprocess test.
  • docs/host-permissions.md: documents the new command positions.

Accumulated diff confirmed: origin/main...48b3c0f, 3731 lines, merge base f22fc1df8d07bce22be8ac519a60b89a3b5a8eb0. The delta (3 files, +129/−24) and the current _command_position / _shell_expansion_end / _shell_segments were read in full. The diff's SHA-256 could not be recomputed: sha256sum is not in this stage's command table. The trusted history (author datacas, per code_cycle.review.trusted_authors) has REV-001–REV-014 with no gaps or collisions.

Findings

[REV-001] · high · resolved · valid · blocks:yes — Regex grants match raw compound shell source, so a simple-command pattern authorizes other segments

Still resolved: the regression suite covering it passes at this head.

[REV-002] · medium · resolved · valid · blocks:yes — The segment credential guard compares literal paths, so cd options, pushd and globs get past it

Still resolved: the regression suite covering it passes at this head.

[REV-003] · medium · resolved · valid · blocks:no — Every consent question names the configured test command, even for unrelated commands

Still resolved: the regression suite covering it passes at this head.

[REV-004] · medium · resolved · valid · blocks:no — An invalid edited pattern, or forever for review, ends the whole cycle instead of asking again

Still resolved: the regression suite covering it passes at this head.

[REV-005] · low · resolved · valid · blocks:no — The "Codex" AC-8 parity test does not exercise Codex

Still resolved: the regression suite covering it passes at this head. Native Codex parity itself stays unverified (see Verification).

[REV-006] · medium · resolved · valid · blocks:yes — A relative argument after cd "$VAR" is refused with no consent question, even when it is not a path

Still resolved: the regression suite covering it passes at this head.

[REV-007] · low · resolved · valid · blocks:no — Glob credential matching lets * cross /, so unrelated absolute globs count as credential reads

Still resolved: the regression suite covering it passes at this head.

[REV-008] · medium · resolved · valid · blocks:yes — builtin cd, command cd and CDPATH still get past the segment credential guard

Still resolved: the regression suite covering it passes at this head.

[REV-009] · medium · resolved · valid · blocks:yes — Tilde prefixes ~user, ~+ and ~- are expanded as ~, so the credential guard checks the wrong path

Still resolved: the regression suite covering it passes at this head.

[REV-010] · low · resolved · valid · blocks:no — The env -C guard applies only when env is the program word, so command env -C "$X" and wrapped forms get past it

Still resolved: the regression suite covering it passes at this head.

[REV-011] · medium · resolved · valid · blocks:yes — CDPATH, HOME, OLDPWD, dotglob and GLOBIGNORE are detected in the raw source, so continuations and quoting the parser decodes hide them

Still resolved: the regression suite covering it passes at this head.

[REV-012] · medium · resolved · valid · blocks:yes — Glob options other than dotglob are not modelled, so nocaseglob lets a differently cased glob reach a store

Still resolved: the regression suite covering it passes at this head.

[REV-013] · medium · resolved · valid · blocks:yes — The extglob tokenizer counts parentheses inside ${…} and $[…], so it folds the commands after an extglob into one operand

Still resolved: the REV-013 tests pass at this head.

[REV-014] · medium · open · valid · blocks:yes — A case pattern's ) inside $(…) ends the substitution early, so later commands are hidden from the segment guards

scripts/stage_permissions.py:557-628 (_COMMAND_PREFIX_WORD, _FUNCTION_HEADER, _command_position) and :767-773 (where case tracking starts).

Fixed and verified: the four residual classes from the previous rereview (function bodies, time -p/time --, coproc [NAME], keywords split by line continuations) are in REV014_FORMS / REV014_TIME_FORMS. They run in the Claude/Codex × resolve/rereview matrix and in the disposable-Bash baseline, and pass (issue-439-regression: 50 tests, OK). The argument-position negatives keep their boundaries.

Still reproducible (static trace). _command_position checks each prefix keyword it strips (:625-628) to see whether that keyword was itself at command position. do and { are accepted only after ;, &, |, a newline or another prefix keyword. Bash also accepts them right after a for header with no separator:

  1. for ((…)) do … and for ((…)) { …; }. These are FOR ARITH_FOR_EXPRS DO and FOR ARITH_FOR_EXPRS '{' in parse.y. Take printf '%s' "$(for ((;;)) do case a in a) git push --force origin main ;; esac; break; done)". Once do is stripped, before is for ((;;)). Its last character is a ) that is not pattern_close, and _FUNCTION_HEADER needs empty parentheses, so _command_position returns False (:613-618). The case is never tracked. The pattern a) drops nesting to 0 (:778-783), and the substitution ends there. _shell_segments re-splits the body for ((;;)) do case a in a into [for] and [case, a, in, a]. The rest ( git push --force origin main ;; esac; break; done)) is data of the outer double-quoted printf word (:852-859, :964-965). No segment has program git, so the .+ compound grant covers the command. Bash runs the loop body once, and the body runs the push.
  2. for NAME do … and select NAME do … (FOR WORD newline_list DO). Example: "$(set -- 1; for x do case a in a) git push --force origin main ;; esac; done)". Here before is for x after do is stripped, and _COMMAND_PREFIX_WORD does not match it. With a non-empty $@ the body runs.

A cat ~/.ssh/id_rsa in the same position escapes credential_reason in the same way. AC-8 (each segment guarded individually) and AC-10 (a pattern matching a protected command grants nothing for it) are still violated. git grep finds no for (( … )) do, for NAME do or select handling in the parser or the consent tests.

Evidence limit: static trace of the code at this head. A runtime probe was refused by the stage command table (python3 -I -c …, permission id command_0952be4ee67932d06fedaa67f2539f2548ec881e839c1e69fa4540dabecd3f92, unanswered). New probe files are outside the rereview edit rule.

Suggested fix: the tracker still fails open on each position it does not list. That is now the fifth round of enumeration. Suggested fail-closed rule: inside a substitution body, when the tracker sees an unquoted case word that it does not open, either open it anyway or raise PolicyError (interpreter consent with the protected guards still applied). Opening it is safe: the substitution only gets longer, or the parse fails as unterminated. If enumeration is kept, accept do/{ after for ((…)), for NAME and select NAME, and add both forms above to REV014_FORMS and the Bash baseline.

Security triage and audit

The deterministic minimum did not fire: no CI, secret or agent-configuration path changed, and the PR has no labels. The runtime plan sets security_required: true, and the change is to the permission parser, so cc-security-review ran on the delta and on the accumulated parser/guard surface at this head.

  • Confirmed (static trace), Medium: the residual REV-014 forms above. Precondition: a compound pattern grant, or a consent answer for the visible segments. Impact: a protected command (git push, credential-store read) runs without its guard, and the consent question does not name it. Mitigation as suggested above.
  • Reviewed, no issue found: continuation stripping inside single quotes cannot produce a false separator. The last character of before is always outside quotes or a closing quote. The _FUNCTION_HEADER / _COMMAND_PREFIX_WORD searches keep a negative lookbehind, so each word boundary is tried only once; no catastrophic backtracking observed by inspection. Over-recognising NAME() (an extglob @() with extglob on) fails safe.
  • Informational, not measured: _command_position now rebuilds a per-character list from the start of the substitution for every case/esac candidate. This is O(n·k) Python work within the 64 KiB limit. It affects only the stage's own hook latency (previously O(n²) slicing).
  • Potential risk, carried over, not reproduced: in Bash POSIX mode, single quotes inside a double-quoted ${x:-…} within an extglob. Aliases remain outside the parser model. External sandbox isolation remains the second layer.

security_audit_ran=true.

Verification — agent-reported, tests.version=2

All checks ran in this stage's disposable clone at 48b3c0f501bb1fb47725238c82422bf476164949, in the foreground.

Frozen check ID Executor/profile Result Evidence
configured-test codex/deep_coder pass (exit 0) Ran 2561 tests in 285.031s — OK (skipped=1)
issue-439-regression codex/deep_coder pass (exit 0) Ran 50 tests in 12.471s — OK
package-validation codex/deep_coder pass (exit 0) VALID: 16 skills (7 cycle, 9 supporting), shared sections in sync, cross-agent manifests aligned
type-check codex/deep_coder pass (exit 0) 0 errors, 0 warnings, 0 notes
native-claude-parity claude/deep_coder unverified The frozen identity is an opaque command digest with no runnable binding in this stage. The shared-hook unit tests are not native executor evidence.
native-codex-parity codex/deep_coder unverified Same as above. In addition, the nested Codex socket mask prevents launching codex exec/sandbox from a stage (docs/routing.md).
consent-characterization codex/deep_coder pass (exit 0) Ran 6 tests in 15.676s — OK

Conclusion: not_verified. The two required native parity checks (AC-8) did not run. AC-8 and AC-10 also stay open because of REV-014: the passing suite does not exercise the for-header forms. AC-1–AC-7, AC-9, AC-11 and AC-12 have passing linked regression coverage.

3 passed, 0 failed, 2 pending, 1 missing. The cycle's CI gate decides on these; none is a finding.

Residual risk and verdict

The static Bash model is still not a full grammar. Reserved-word positions it does not list are where it fails open. Verdict: CHANGES_REQUESTED (REV-014).

Functional status: RESOLVED at 16ded03b3ed341a931e5dfb52a3af119a00153b9. This attempt resolves REV-014. Required native parity remains pending (tests.conclusion=not_verified); this is not a merge-readiness claim. The invoking checkout and working branch were reused.

Diagnosis and evidence before editing

Recovered all 16 provider comments in chronological order through the repository's trusted-author contract (datacas): REV-001–REV-014, no collisions, gaps or recovery errors. No native review threads exist. Dispositions were frozen on 48b3c0f501bb1fb47725238c82422bf476164949 before source edits; REV-014 stays valid.

The supplied accumulated diff was confirmed at 3,731 lines and SHA-256 625bb30412fa4f6219d157dbe99f00ed3eac9b483006d680b280d595a5205674, and read in sections. The trusted delta base 48b3c0f501bb1fb47725238c82422bf476164949 is an ancestor of the fix commit; the delegated final review judged that delta (3 files), with accumulated context.

The reviewer's exact arithmetic-for do/brace and positional for x do/select x do reproductions were run before editing using python3 "$TMPDIR/reproduce-rev014.py". All four hid git push --force origin main from the segment list and returned protected_reason=None and allowed=True under a compound pattern grant in Claude/Codex × resolve/rereview. Disposable Bash fixtures exited 0 and printed hidden command ran; no protected store or real Git push was executed. Credential reads also escaped in three forms; the arithmetic brace form already retained the credential guard, while its push still escaped. The original 50-test regression suite passed despite this defect.

Cause confirmed: _command_position stripped do/{ but did not recognise the preceding loop header. Consequently the case pattern's ) closed the substitution, and the body became outer quoted data. The invariant is that executable body commands remain independent segments before consent matching and concrete guards. Diagnosis: shared_cause, decision implement_root_fix, within #439/#455 scope. Related-work search was widened across open/closed issues and merged PRs for shell/consent and the parser components; relevant existing work includes #398, #406, #431, #450, #455 and #464. #455 remains open.

Current finding

[REV-014] · medium · resolved · valid · blocks:yes — A case pattern's ) inside $(…) ends the substitution early, so later commands are hidden from the segment guards

Fixed in 16ded03b3ed341a931e5dfb52a3af119a00153b9. Loop-body recognition accepts arithmetic for headers and positional for/select headers only after a body opener, and checks the header's own command position. Arithmetic matching reuses the expansion delimiter scanner so an earlier extglob cannot consume the actual header. Positional do also starts a new segment, preserving the guard on a direct first body command.

The required delegated cc-code-review/cc-security-review found and reproduced two intermediate residuals: greedy header matching across extglob data and an unsplit direct positional-loop body. Both were corrected and independently re-probed before completion. Current reproductions expose the protected push as its own segment and deny it, while their disposable Bash baselines still execute their markers. for do do was also checked. No not_applicable claim is made.

Regression coverage extends the existing matrix with 17 loop forms, safe consent, protected push/credential rejection, argument-position negatives, disposable Bash baselines and real hook subprocess allow/deny cases. The owning docs/host-permissions.md now describes these boundaries. This PR already updates the consent/configuration pages, parity audit and #439/#455 roadmap; no issue was closed or changed by this attempt.

Preserved history

REV-001–REV-013 retain their recovered status/disposition below. The current regression suite covers their retained guards. They are not new resolution claims in this attempt's receipt.

[REV-001] · high · resolved · valid · blocks:yes — Regex grants match raw compound shell source, so a simple-command pattern authorizes other segments

[REV-002] · medium · resolved · valid · blocks:yes — The segment credential guard compares literal paths, so cd options, pushd and globs get past it

[REV-003] · medium · resolved · valid · blocks:no — Every consent question names the configured test command, even for unrelated commands

[REV-004] · medium · resolved · valid · blocks:no — An invalid edited pattern, or forever for review, ends the whole cycle instead of asking again

[REV-007] · low · resolved · valid · blocks:no — Glob credential matching lets * cross /, so unrelated absolute globs count as credential reads

[REV-008] · medium · resolved · valid · blocks:yes — builtin cd, command cd and CDPATH still get past the segment credential guard

[REV-009] · medium · resolved · valid · blocks:yes — Tilde prefixes ~user, ~+ and ~- are expanded as ~, so the credential guard checks the wrong path

[REV-010] · low · resolved · valid · blocks:no — The env -C guard applies only when env is the program word, so command env -C "$X" and wrapped forms get past it

[REV-011] · medium · resolved · valid · blocks:yes — CDPATH, HOME, OLDPWD, dotglob and GLOBIGNORE are detected in the raw source, so continuations and quoting the parser decodes hide them

[REV-012] · medium · resolved · valid · blocks:yes — Glob options other than dotglob are not modelled, so nocaseglob lets a differently cased glob reach a store

[REV-013] · medium · resolved · valid · blocks:yes — The extglob tokenizer counts parentheses inside ${…} and $[…], so it folds the commands after an extglob into one operand

Security audit

cc-security-review ran because the runtime plan requires it and the delta changes authorization parsing. It reviewed substitution boundaries, arithmetic-header bounds, recursion-budget propagation, positional body splitting, argument data, grant/guard separation, tests and documentation. No remaining confirmed vulnerability or P0/P1 finding was found in the final delta. security_audit_ran=true.

Residual limitation: this is a partial static Bash model. Dynamic interpreter behaviour still relies on external isolation. Real hook subprocesses and shared metadata matrices do not establish native Claude/Codex parity.

Verification — agent-reported, tests.version=2

The five runnable frozen checks passed on the final committed source. The full suite reports 2,561 discovered tests, one skipped (2,560 executed); the regression suite reports 50 tests; characterization reports six; package validation passes; BasedPyright reports zero errors/warnings/notes. An earlier full run passed but was superseded because source changed during it; it is not used as final-head evidence. The original reproduction was rerun with --assert-fixed and passed. An initial candidate regression failure was corrected before the final run.

AC-1–AC-7 and AC-9–AC-12 have passing linked regression evidence. AC-8 stays open because its two required native executor checks did not run. The runtime supplied only opaque command digests; a search of the repository, installed runtime and evidence found no executable binding. The nested-executor table in docs/routing.md supplies no verified alternative, and the known Codex socket mask excludes nested Codex launches here. No executor was substituted and no setup/CI result is counted as local execution.

Status: CHANGES_REQUESTED on head 16ded03b3ed341a931e5dfb52a3af119a00153b9. REV-014 is fixed and verified: both for-header forms from the previous rereview are covered and their tests pass. One new finding, REV-015: a { body after for NAME, select NAME or function NAME, and a coproc command, keep the body's first command inside a segment whose program is the keyword. That command then skips its program-specific guards (git push, ref deletion, gh, find -exec).

Changes since the previous rereview (48b3c0f → 16ded03)

  • scripts/stage_permissions.py: new _LOOP_BODY_HEADER, _ARITHMETIC_FOR_HEADER and _loop_body_header(). When _command_position strips do or {, it now also strips a preceding for ((…)), for NAME or select NAME header, then checks the header's own command position. The arithmetic header is delimited by _shell_expansion_end, and a resource-limit PolicyError from it is re-raised. _shell_segments now starts a new segment at a positional do (for x do CMD).
  • tests/test_consent_variants.py: 17 REV014_LOOP_FORMS (2 extglob forms included), argument-position negatives (echo for x do case …), and real hook subprocess allow/deny cases for push and credential bodies. The Bash baseline runs the extglob forms with -O extglob and feeds stdin to select.
  • docs/host-permissions.md: documents the loop-body command positions.

The accumulated diff file was confirmed at 3818 lines (origin/main...16ded03, merge base f22fc1df8d07bce22be8ac519a60b89a3b5a8eb0). Since 48b3c0f, only the three files above changed (git diff --stat: +107/−20). That delta was read in full, along with the current _loop_body_header, _command_position, _shell_segments, _compound_analysis and protected_reason. The SHA-256 was not recomputed: sha256sum is not in this stage's command table. Trusted history (author datacas, per code_cycle.review.trusted_authors): REV-001–REV-014, no gaps or collisions. The new finding is REV-015.

[REV-012] · medium · resolved · valid · blocks:yes — Glob options other than dotglob are not modelled, so nocaseglob lets a differently cased glob reach a store

Still resolved: its regression suite passes at this head.

[REV-013] · medium · resolved · valid · blocks:yes — The extglob tokenizer counts parentheses inside ${…} and $[…], so it folds the commands after an extglob into one operand

Still resolved: the REV-013 tests pass at this head.

[REV-014] · medium · resolved · valid · blocks:yes — A case pattern's ) inside $(…) ends the substitution early, so later commands are hidden from the segment guards

scripts/stage_permissions.py:562-587 and :655-660.

Corrected and verified by execution. The two residual classes from the previous rereview are now in REV014_LOOP_FORMS: for ((…)) do / for ((…)) {, and for NAME do / select NAME do. The literal reproductions are REV014_LOOP_FORMS[0] and [2]. The forms run in the Claude/Codex × resolve/rereview matrix and in the disposable-Bash baseline, which shows the hidden command runs. A real stage_permissions.py hook subprocess allows printf safe and denies git push --force origin main and cat ~/.ssh/id_rsa with [layer=toolkit_hook]. All pass (issue-439-regression: Ran 50 tests — OK).

Static trace confirms the mechanism. For for ((;;)) do case, stripping do leaves for ((;;)). _loop_body_header delimits $((;;)) with _shell_expansion_end, which ends at the last character, so before becomes empty and the case is tracked. For for x do case, _LOOP_BODY_HEADER matches for x. The argument-position negatives (echo for x do case a in a, the quoted "for ((;;))") keep _command_position false: the header's own position is checked on the next loop pass.

[REV-015] · medium · open · - · blocks:yes — A { body after for NAME, select NAME or function NAME, and coproc, keep the body's first command inside the keyword's segment

scripts/stage_permissions.py:847-857 (finish_segment), :894-903 (the new positional-do split) and :4054-4074 (protected_reason dispatches its guards on words[0]).

The fix for REV-014 added a positional-do split for one reason: so that "its first body command retains its own guards even without a case clause" (docs/host-permissions.md). The { form of the same grammar was not split. Bash also accepts these bodies with no separator, and _COMMAND_PREFIX_WORD / _loop_body_header already treat them as command positions:

  • for NAME { …; } and select NAME { …; } (parse.y FOR WORD newline_list '{' compound_list '}', and the matching select_command rule);
  • function NAME { …; } (no parentheses);
  • coproc CMD … and coproc NAME { …; }.

In _shell_segments, { is an ordinary word. finish_segment strips a leading {, do, if, !, time, … only when it is words[0]. Static trace of set -- 1; for x { git push --force origin main; }:

  1. The segments are [set, --, 1], [for, x, {, git, push, --force, origin, main] and [}]. The last one is stripped to nothing.
  2. In protected_reason, program is for, so _check_push / _check_git never run. The same happens with program == "function" for function f { git push --force origin main; }; f, and with coproc for coproc git push --force origin main.
  3. Under a compound pattern grant such as the suite's .+ (rev014_grant), the segment matches and nothing is protected, so the push runs. Bash runs the body once with a non-empty $@. A function body runs on its call, and a coproc runs at once.
  4. The same position inside a substitution, "$(set -- 1; for x { git push --force origin main; })", gives the same segment.

Not affected: credential reads and redirects. credential_reason scans every word after the program, so for x { cat ~/.ssh/id_rsa; } is still refused, and segment redirects are still checked. The )-delimited forms (f() { …; }, for ((…)) { …; }) split correctly. Only guards keyed to the program word are skipped: git push, Git ref deletion, gh, find -exec. AC-8 (each segment guarded individually) and AC-10 (a pattern that matches a protected command grants nothing for it) are violated for these forms. git grep finds no for x {, select x {, function f { or coproc body test in tests/test_consent_variants.py.

Evidence limit: static trace of the code at this head, with the grammar taken from Bash's parse.y. A runtime probe file was refused by this stage's edit rule (Write $TMPDIR/probe_rereview.py, permission id command_3b3ce823c2cfefd849e00b6c84347e831413022bc7b097402fd846eb39dedca4, unanswered). The refusal was not bypassed. The resolver should reproduce the forms in disposable Bash and with parse_command(...).segments before fixing.

Suggested fix: make finish_segment strip compound headers before the body. Drop for|select NAME {, function NAME { and coproc [NAME] { (keeping the remaining words), and drop a leading coproc before a simple command. As a fail-closed backstop, when a segment's program word is a shell reserved word (for, select, function, coproc, case, …), run protected_reason on every word suffix of that segment, so an unmodelled header can only add guards. Add these forms to REV014_LOOP_FORMS (or a new tuple), the Bash baseline and the hook subprocess deny cases.

Security triage and audit

The deterministic minimum did not fire: no CI, secret or agent-configuration path changed, and the PR has no labels. The runtime plan sets security_required: true, and the change is to the permission parser, so cc-security-review ran as a delegated pass on the delta and on the accumulated segment/guard surface at this head.

  • Confirmed (static trace), Medium: REV-015 above. Precondition: a compound pattern grant, or consent given to a for …/function …/coproc … segment. Impact: a direct git push (or ref deletion, a gh write, find -exec) runs without its guard. The guard's refusal text is never shown.
  • Reviewed, no issue found: _loop_body_header re-raises non-unterminated PolicyErrors, so the depth limit still fails closed (protected_reason returns the error string). _LOOP_BODY_HEADER and _ARITHMETIC_FOR_HEADER are linear (a single lookbehind, no nested quantifiers). The positional-do split only adds segments, which fails safe. echo for x do git push does not split, because _command_position rejects the echo prefix, and the words stay data. Quoted header text ("for ((;;))") is excluded: the expansion scanner reports it unterminated, and that header is skipped.
  • Informational, not measured: every do word in _shell_segments and every do/{ stripped in _command_position now runs _loop_body_header. That function walks every for (( occurrence in the prefix with _shell_expansion_end, which is O(n·k) within the 64 KiB limit. It affects only the hook's own latency.
  • Potential risk, carried over, not reproduced: aliases and Bash POSIX-mode quoting are outside the parser model. External sandbox isolation remains the second layer.

security_audit_ran=true.

Verification — agent-reported, tests.version=2

All runnable checks ran in this stage's disposable clone at 16ded03b3ed341a931e5dfb52a3af119a00153b9, in the foreground, with logs in $TMPDIR/<check>.log.

Frozen check ID Executor/profile Result Evidence
configured-test codex/deep_coder pass (exit 0) Ran 2561 tests in 353.993s — OK (skipped=1)
issue-439-regression codex/deep_coder pass (exit 0) Ran 50 tests in 27.619s — OK
package-validation codex/deep_coder pass (exit 0) VALID: 16 skills (7 cycle, 9 supporting), shared sections in sync, cross-agent manifests aligned
type-check codex/deep_coder pass (exit 0) 0 errors, 0 warnings, 0 notes
native-claude-parity claude/deep_coder unverified The frozen identity is an opaque command digest with no runnable binding in this stage. Shared-hook unit tests are not native executor evidence.
native-codex-parity codex/deep_coder unverified Same as above. In addition, the nested Codex socket mask prevents launching codex exec/sandbox from a stage (docs/routing.md).
consent-characterization codex/deep_coder pass (exit 0) Ran 6 tests in 20.549s — OK

Conclusion: not_verified. The two required native parity checks (AC-8) did not run. AC-8 and AC-10 also stay open because of REV-015: the passing suite does not exercise the {-body and coproc forms. AC-1–AC-7, AC-9, AC-11 and AC-12 have passing linked regression coverage.

6 passed, 0 failed, 0 pending. The cycle's CI gate decides on these; none is a finding.

Residual risk and verdict

The static Bash model is still not a full grammar. Any compound header it does not strip leaves a direct command behind a keyword program word. The suggested backstop (guarding every word suffix of a keyword segment) would close that class instead of enumerating it. Verdict: CHANGES_REQUESTED (REV-015).

)

A body behind for/select NAME {, function NAME, coproc [NAME], time or ! kept the keyword as the segment program, so git push, ref deletion, gh and find -exec guards never ran on it (REV-015). Peel those headers in one helper used both for segments and for the !( negation check, and route bare time/!/coproc commands through shell analysis.

Status: RESOLVED at head a1c0dc024a00370b3b65a1e16c281958ca21d22c (fix commit a1c0dc0, pushed and confirmed as the PR head). REV-015 is fixed and covered by regression tests. REV-014 was reproduced again with the reviewer's own reproductions before any edit, and it does not reproduce at 16ded03 or at a1c0dc0. The two required native parity checks remain unverified, so the verification conclusion is not_verified. This is not merge approval.

Triage: every finding was classified against 16ded03b3ed341a931e5dfb52a3af119a00153b9 before editing. Trusted history (author datacas): REV-001–REV-015, no gaps or collisions. No review threads exist on this PR. No earlier comment carries the receipt of attempt-720fb5e2421e4102ac23ea96d15baa6b, so this is a new comment.

This dispatch resumed a quota-interrupted Codex worktree. Its uncommitted REV-015 work was inspected, kept, and extended. It was not reset.

[REV-013] · medium · resolved · valid · blocks:yes — The extglob tokenizer counts parentheses inside ${…} and $[…], so it folds the commands after an extglob into one operand

Unchanged. Its regression tests pass at a1c0dc0.

[REV-014] · medium · resolved · valid · blocks:yes — A case pattern's ) inside $(…) ends the substitution early, so later commands are hidden from the segment guards

Named as contested by the runtime. Reproduced again before editing; it does not reproduce. The runtime named REV-014 as reopened by a re-review. That reopening was the 48b3c0f rereview. The 16ded03 rereview (CCR-20261110-003) then marked it resolved, based on its own static trace and passing tests. This attempt did not rely on that. Before any edit, the HEAD file 16ded03:scripts/stage_permissions.py was loaded in a disposable test module, and parse_command(...).segments and protected_reason were run on these commands:

  • the reviewer's literal reproductions: printf '%s' "$(for ((;;)) do case a in a) git push --force origin main ;; esac; break; done)" and printf '%s' "$(set -- 1; for x do case a in a) git push --force origin main ;; esac; done)";
  • the cat ~/.ssh/id_rsa variant;
  • the same case body behind for ((;;)) {, for x {, for x+newline+{, function f {, function f-x {, function f if, coproc, coproc w {, time, time -p --, !, time coproc and select x {.

Every one yields a separate git push --force origin main (or cat …/.ssh/id_rsa) segment, and protected_reason refuses it (git push --force is never allowed / protected credential reads cannot be granted). The same probe in disposable Bash, with git/cat stubbed as functions, shows that each body really runs. The result is identical at a1c0dc0. The status stays resolved and the disposition stays valid. This is fresh execution evidence, not a not_applicable claim.

[REV-015] · medium · resolved · valid · blocks:yes — A { body after for NAME, select NAME or function NAME, and coproc, keep the body's first command inside the keyword's segment

Reproduced at 16ded03 before the fix. With the HEAD parser:

  • set -- 1; for x { git push --force origin main; } → segment [for, x, {, git, push, …], and protected_reason returns None.
  • The same happens for select x {, function f {, function f if …, coproc git push …, coproc worker {…}, coproc git {…}, the $(…) form, time coproc, ! coproc, and also bare time git push --force origin main, ! git push … and time -p -- git push …. _parse_simple accepted these as one simple command whose program was the keyword.

In disposable Bash, function f { …; }; f, function f if …, for x+newline+{ …; }, time … and time -p -- … run the stubbed git push. The coprocess forms start the body asynchronously. The single-line for x { …; } / select x { …; } is a syntax error in this Bash, so those two spellings are only analysed conservatively.

Cause. finish_segment removed only one leading word from a fixed set (if, do, {, !, …) and one time. Multi-word headers (for|select NAME {, function NAME, coproc [NAME]) and repeated headers stayed in the segment, so the guards keyed on words[0] (git push, Git ref deletion, gh, find -exec) never ran. Separately, parse_command returned the _parse_simple result for operator-free time CMD / ! CMD / coproc CMD.

Fix (a1c0dc0, scripts/stage_permissions.py).

  • New _peel_command_headers() removes these headers repeatedly: if/then/elif/else/while/until/do/!/{/}, time [-p] [--], function NAME, for|select NAME {, and coproc [NAME]. A name is removed only before a compound body ({, [[, if, while, until, for, select, case, or a ( that ends the segment). coproc git push keeps git as the program.
  • parse_command sends a leading time, ! or coproc through shell analysis, so those commands get the same guards and shell consent.
  • The delegated post-change review found one P1 in the first version of this fix: the !( negation check (REV-012) used its own fixed prefix set. function f { !(git push --force origin main); }; f, coproc { !(…); }, select x+newline+{ !(…); … } and function f if !(…); … read the subshell as one extglob operand. That check now uses the same helper (after environment assignments), and those four forms are in the tests.
  • Header words in argument position stay data: echo function f { git push …, printf '%s\n' coproc git push, echo time coproc git push …. for x in git push --force; do … is not refused.

Regression tests (tests/test_consent_variants.py).

  • REV015_FORMS has 23 forms. Five protected bodies (git push --force, git branch -D, gh pr merge, find -exec, cat ~/.ssh/id_rsa) run under Claude/Codex × resolve/rereview with a .+ compound grant. Each command must produce the body's own segment, a protected_reason, a check() denial and no refused_operation.
  • A disposable-Bash baseline, with every protected program stubbed to write a marker, shows that the hidden body executes. A real stage_permissions.py hook subprocess allows printf safe under an exact grant and denies each protected body with [layer=toolkit_hook].
  • test_rev015_coproc_name_is_not_a_program checks that coproc NAME (…), coproc NAME {…} and coproc NAME [[…]] do not produce a NAME program.
  • test_rev015_header_words_in_arguments_remain_data covers the argument-position negatives.

docs/host-permissions.md documents the header rule and the shared !( decision.

Not adopted: the suggested backstop that guards every word suffix of a keyword segment. It would refuse data such as for x in git push --force; do echo "$x"; done. That would be a new toolkit veto under the capability-parity rule in AGENTS.md (#450). The header enumeration is now shared by both decision points instead.

Post-change review and security triage

  • Delta base 16ded03b3ed341a931e5dfb52a3af119a00153b9 (latest trusted rereview receipt). git merge-base --is-ancestor 16ded03 HEAD succeeded, so the fix delta was reviewed rather than the accumulated diff.
  • The delegated cc-code-review pass on that delta found one P1, the !( path above. It was fixed and tested in the same commit. The pass found no other header form that leaves a program behind a keyword, and no argument-position false refusal. It checked that the parse_command keyword routing keeps timeout 5 x, !x and coprocfoo on the simple path.
  • Deterministic security minimum: no CI, secret or agent-configuration path changed, and the PR has no labels. The runtime plan has security_required: false, so cc-security-review did not run as a separate stage pass (security_audit_ran=false). The delegated delta review was explicitly scoped to guard bypasses and false refusals in this permission parser.

Verification — agent-reported, tests.version=2

All runnable checks ran locally in the foreground on the final tree, which was then committed unchanged as a1c0dc0. Logs are in $TMPDIR/<check>.log.

Frozen check ID Executor/profile Result Evidence
configured-test codex/deep_coder pass (exit 0) Ran 2565 tests in 385.362s — OK (skipped=1)
issue-439-regression codex/deep_coder pass (exit 0) Ran 54 tests in 45.586s — OK
package-validation codex/deep_coder pass (exit 0) VALID: 16 skills (7 cycle, 9 supporting), shared sections in sync, cross-agent manifests aligned
type-check codex/deep_coder pass (exit 0) 0 errors, 0 warnings, 0 notes
native-claude-parity claude/deep_coder unverified The frozen identity is an opaque command digest with no runnable binding in this stage. Shared-hook unit tests are not native executor evidence.
native-codex-parity codex/deep_coder unverified Same as above. In addition, the nested Codex socket mask prevents launching codex exec/sandbox from a stage (docs/routing.md).
consent-characterization codex/deep_coder pass (exit 0) Ran 6 tests in 7.821s — OK

An earlier full run in this stage failed 2 tests (test_windows_shard_manifest_covers_each_test_module_once, test_run_fast_keeps_only_the_tests_of_the_shard). The only cause was this stage's own untracked probe module tests/test_zz_probe_rev015.py, which had no Windows shard assignment. The probe was removed and never committed, and the rerun above passed.

Conclusion: not_verified. Two required native parity checks (AC-8) did not run. AC-1–AC-7 and AC-9–AC-12 have passing linked regression coverage. AC-8 has passing shared-hook coverage, including the REV-015 forms, but stays open until native parity runs.

Environment shared with CI: Python stdlib unittest, and Bash for the posix_shell baselines. Not shared: the local Linux/WSL Bash version. CI runs these suites on Windows shards, where the posix_shell cases may be skipped.

Permissions

These accessory operations were refused by the resolve command table and were not bypassed: python3 -I $TMPDIR/report.md head (probe script, command_01a49aceade2d0dc23210b6577e897666ecc83fa03724711a88a3d15559e1855); rm, mv and git clean of the untracked probe (command_bcf49eb6…, command_889941da…, command_7786c932…). The reproduction ran instead as a temporary unittest module. That module was removed with git add + git rm -f and was never committed.

CI (head a1c0dc0, read once; parallel policy)

When read once right after the push, statusCheckRollup was empty: 0 passed, 0 failed, 0 pending. No check had registered yet on a1c0dc0. The cycle's CI gate decides on the six expected checks when they report. None of them is a finding.

Residual risk

The static Bash model is still not a full grammar. Aliases and Bash POSIX-mode quoting are outside it, and external sandbox isolation remains the second layer. Launcher programs (command, /usr/bin/time after an assignment, env, …) keep their documented interpreter-consent treatment. That treatment is unchanged by this round.

Status: CHANGES_REQUESTED on head a1c0dc024a00370b3b65a1e16c281958ca21d22c. REV-015 is fixed and verified by execution: all 23 header forms plus the two single-line loop spellings are covered and pass. One new finding, REV-016. The named-coproc rule in _peel_command_headers reads dequoted words, so a quoted reserved word such as "if" after coproc find is taken as a compound keyword. find is then dropped as a coprocess name, and its -exec/-delete guard never runs.

Changes since the previous rereview (16ded03 → a1c0dc0)

  • scripts/stage_permissions.py: new _peel_command_headers(), used by finish_segment and by the !( negation check. parse_command now sends operator-free commands that start with coproc, time or ! through shell analysis.
  • tests/test_consent_variants.py: REV015_FORMS (23 forms) in the Claude/Codex × resolve/rereview matrix with five protected bodies, a disposable-Bash baseline, real hook subprocess allow/deny, the coproc-name and argument-position negatives.
  • docs/host-permissions.md: documents the header rule.

The accumulated diff file was confirmed at 3973 lines (origin/main...a1c0dc0, merge base f22fc1df8d07bce22be8ac519a60b89a3b5a8eb0). The delta (git diff --stat: 3 files, +166/−11) was read in full, along with the current parse_command, _shell_segments tokenizer (quote handling), protected_reason, hidden_program and the LAUNCHERS table. The SHA-256 was not recomputed: sha256sum is not in this stage's command table. Trusted history (author datacas, per code_cycle.review.trusted_authors): REV-001–REV-015, no gaps or collisions. The new finding is REV-016.

scripts/stage_permissions.py:828-857, :477-479.

Corrected and verified by execution. Every form named in the previous rereview is covered by tests that ran here:

  • test_rev015_body_programs_keep_their_guards: function f {, function f-x {, coproc CMD, coproc {, coproc NAME {/(, coproc git {, time !, time coproc, ! coproc, function f if, for x/select x + newline + {, inside $(…), and the single-line for x {/select x {. Five protected bodies run under Claude/Codex × resolve/rereview with the .+ compound grant. Each one must yield its own program segment, a protected_reason, a check() denial and no refused_operation.
  • test_rev015_bash_baseline_and_real_hook_allow_and_deny: disposable Bash shows that each hidden body runs. A real stage_permissions.py hook subprocess allows printf safe under an exact grant and denies each protected body with [layer=toolkit_hook].
  • The coproc-name and argument-position negatives (echo coproc git push …, printf "%s" function f { git push …) keep header words as data.

All pass (issue-439-regression: Ran 54 tests — OK). Static trace agrees: finish_segment peels repeatedly, and a leading time/!/coproc no longer returns the _parse_simple result. The quoted-word residual of the named-coproc rule is a different root cause and is reported as REV-016.

[REV-016] · medium · open · - · blocks:yes — A quoted reserved word after coproc NAME is read as a compound keyword, so the coprocess program is dropped and its guards are skipped

scripts/stage_permissions.py:850-854 (_peel_command_headers, the named-coproc branch), with the tokenizer's quote handling at :917-924.

The coproc branch decides whether words[1] is a coprocess NAME by checking words[2] in {"{", "[[", "if", "while", "until", "for", "select", "case"}. _shell_segments removes quotes before it appends a word (:917-924, finish_word), so "if", \if and '{' reach that check as if and {. Bash only recognises reserved words when they are unquoted. coproc find "if" src -delete is therefore the simple coprocess find if src -delete: find reports that if is missing, then deletes src.

Static trace of coproc find "if" src -delete at this head:

  1. parse_command: _parse_simple succeeds, the leading coproc routes it to _shell_segments (:477-479).
  2. Words: [coproc, find, if, src, -delete]. named is true because words[2] == "if", so coproc find is dropped. The loop then peels if, and the segment is [src, -delete].
  3. In protected_reason the program is src, so the find branch (FIND_FORBIDDEN: -exec, -execdir, -ok, -delete, -fprint*, -fls) never runs. credential_reason still scans the remaining words, so credential reads stay refused. Only the find execute/write guard is lost.
  4. The same happens with coproc find "{" src -exec rm -rf {} +, coproc find \while src -delete, coproc find "[[" … and the $(…) form. Under a compound pattern grant such as the suite's .+, or an exact grant, the segment is allowed. This breaks AC-10 (a pattern matching a protected command grants nothing for it) and AC-8 (each segment guarded individually). The guard docstring states that consent never removes these guards.

git and gh are not affected in practice: a reserved word as their first argument makes them fail. git grep finds no quoted-word coproc form in tests/.

Evidence limit: static trace of the code at this head, with Bash's quoting rule ("reserved words are recognised only when unquoted"). A runtime probe (python3 -I -c … against parse_command, permission id command_3845144a670a99efb0182b18d9dc9279c7e6d5b4309cb02caddb35f21b652a97) was refused by this stage's command table, and the refusal was not bypassed. The resolver should reproduce the form with parse_command(...).segments and in disposable Bash (with find stubbed) before fixing.

Suggested fix: record in finish_word whether a word came from unquoted literal characters. Pass that flag to _peel_command_headers, and only treat words[2] as a compound keyword when it was unquoted. The same flag can gate for|select NAME { and function NAME, though their misreadings are fail-safe today. Add the quoted forms ("if", \if, '{', "[[") with find … -delete/-exec bodies to the REV-015 matrix, the Bash baseline and the hook deny cases.

Security triage and audit

The deterministic minimum did not fire: no CI, secret or agent-configuration path changed, and the PR has no labels. The runtime plan sets security_required: true, and the change is to the permission parser, so cc-security-review ran as a delegated pass on the delta and on the accumulated segment/guard surface at this head.

  • Confirmed (static trace), Medium: REV-016 above. Precondition: a compound pattern grant, or consent to the exact coproc … command. Impact: a find -delete/-exec runs without its direct-command guard, and its refusal text is never shown.
  • Reviewed, no issue found: over-peeling at words[0] ("time", "{", "if") only exposes more programs to their guards, so it fails safe. function NAME and for|select NAME { misreadings need text that Bash rejects as a syntax error. The !( check filters environment assignments before peeling, so echo A=1 !(x) stays an extglob operand. parse_command routing only adds analysis, and !x, timeout 5 x and coprocfoo stay simple (covered by tests). _peel_command_headers is linear in the word count.
  • Potential risk, carried over, not a new finding: wrappers in program position (command git push, nice git push, "time" git push as a simple command) keep the documented wrapper/interpreter treatment (docs/host-permissions.md, "Selecting a wrapper, interpreter … trusts its nested operations"). Aliases and Bash POSIX-mode quoting are outside the parser model. External sandbox isolation remains the second layer.

security_audit_ran=true.

Verification — agent-reported, tests.version=2

All runnable checks ran in this stage's disposable clone at a1c0dc024a00370b3b65a1e16c281958ca21d22c, in the foreground, with logs in $TMPDIR/<check>.log.

Conclusion: not_verified. The two required native parity checks (AC-8) did not run. AC-8 and AC-10 also stay open because of REV-016: the passing suite does not exercise quoted reserved words after coproc NAME. AC-1–AC-7, AC-9, AC-11 and AC-12 have passing linked regression coverage.

Permissions

The stage command table refused one accessory operation, and it was not bypassed: python3 -I -c "…parse_command('coproc find if -exec rm -rf {} +; then :; fi', None)…" (command_3845144a670a99efb0182b18d9dc9279c7e6d5b4309cb02caddb35f21b652a97). Because of it, REV-016 rests on a static trace. gh pr view … --output was also refused (command_2ac5c3af842e45f7bc007463f094a6e22b13a4f3835d0cda2207489fa74bdbab). A redirect into $TMPDIR replaced it.

Residual risk and verdict

The static Bash model still loses quoting information once a word is built. Any rule that decides command position from a later word, rather than from source offsets as _shell_keyword does, can misread quoted text as syntax. Verdict: CHANGES_REQUESTED (REV-016).

…439)

Bash recognises reserved words and comments before quote removal, but
_shell_segments dequoted each word first. `coproc find "if" src -delete`
was therefore read as a named coprocess and `find` lost its guard
(REV-016). Track per-word quoting and only treat an unquoted word after
`coproc NAME` as a compound keyword. The same loss also dropped empty
quoted words (so `> ""` consumed the next program as its target, and
`coproc find "" if` hid find), let `""#` start a comment, expanded `""~`
as $HOME and read a quoted digit as a redirect descriptor.

Status: RESOLVED at head cca777c7d8add43729f42734de0b25b61bed783b (fix commit cca777c, pushed and confirmed as the PR head). REV-016 is fixed. It was reproduced first: real Bash runs the coprocess program, and the real hook allowed it under the .+ grant. It is now covered by regression tests. REV-014 was named as contested by the runtime. It was re-checked against the reviewer's reproduction at the triage head, and it does not reproduce (details below). Native Claude/Codex parity (AC-8) is still unverified, so verification is not_verified. This is not merge approval.

Triage: every finding was classified against a1c0dc024a00370b3b65a1e16c281958ca21d22c before any edit. REV-016 receives valid. All other dispositions are preserved as they were. Fix-delta base: a1c0dc0, the head of the latest trusted rereview receipt, which is an ancestor of cca777c. The delegated post-change review covered a1c0dc0..cca777c.

Findings

[REV-001] · high · resolved · valid · blocks:yes — Regex grants match raw compound shell source, so a simple-command pattern authorizes other segments

Unchanged; regression suite passes at cca777c.

[REV-002] · medium · resolved · valid · blocks:yes — The segment credential guard compares literal paths, so cd options, pushd and globs get past it

Unchanged; regression suite passes at cca777c.

[REV-003] · medium · resolved · valid · blocks:no — Every consent question names the configured test command, even for unrelated commands

Unchanged.

[REV-004] · medium · resolved · valid · blocks:no — An invalid edited pattern, or forever for review, ends the whole cycle instead of asking again

Unchanged.

[REV-005] · low · resolved · valid · blocks:no — The "Codex" AC-8 parity test does not exercise Codex

Unchanged. Native Codex parity is still unverified (see Verification).

[REV-006] · medium · resolved · valid · blocks:yes — A relative argument after cd "$VAR" is refused with no consent question, even when it is not a path

Unchanged.

[REV-007] · low · resolved · valid · blocks:no — Glob credential matching lets * cross /, so unrelated absolute globs count as credential reads

Unchanged.

[REV-008] · medium · resolved · valid · blocks:yes — builtin cd, command cd and CDPATH still get past the segment credential guard

Unchanged.

[REV-009] · medium · resolved · valid · blocks:yes — Tilde prefixes ~user, ~+ and ~- are expanded as ~, so the credential guard checks the wrong path

Unchanged. ""~ is now also kept literal, as Bash does (part of REV-016).

[REV-010] · low · resolved · valid · blocks:no — The env -C guard applies only when env is the program word, so command env -C "$X" and wrapped forms get past it

Unchanged.

[REV-011] · medium · resolved · valid · blocks:yes — CDPATH, HOME, OLDPWD, dotglob and GLOBIGNORE are detected in the raw source, so continuations and quoting the parser decodes hide them

Unchanged.

[REV-012] · medium · resolved · valid · blocks:yes — Glob options other than dotglob are not modelled, so nocaseglob lets a differently cased glob reach a store

Unchanged.

[REV-013] · medium · resolved · valid · blocks:yes — The extglob tokenizer counts parentheses inside ${…} and $[…], so it folds the commands after an extglob into one operand

Unchanged.

[REV-014] · medium · resolved · valid · blocks:yes — A case pattern's ) inside $(…) ends the substitution early, so later commands are hidden from the segment guards

Contested (survived an earlier claimed fix). This round re-checked it before any edit, using the reviewer's own reproduction:

  • REV014_FORMS, REV014_LOOP_FORMS, REV014_TIME_FORMS and REV014_EXTGLOB_FORMS ran in test_rev014_case_patterns_do_not_end_substitutions, test_rev014_bash_fixture_runs_the_command_after_the_pattern (disposable Bash shows that the hidden command runs) and test_rev014_safe_cases_get_consent_and_real_hook_retains_guards (real hook subprocess).
  • All of them pass at the triage head a1c0dc0 and at cca777c. Every hidden git push/credential read is its own segment, and the hook denies it.
  • Cause re-derived: the ) of a case pattern and the ;;/;&/;;& terminators are tracked to esac by _shell_expansion_end and _shell_keyword, which work on source offsets. The reopening came from the loop-header forms. Those are fixed in 16ded03, and the rereview at a1c0dc0 found them resolved.

The evidence the reopening rereview did not have is that later rereview (CCR-20261110-004), plus this round's execution. REV-014 stays resolved, not not_applicable. Its disposition is unchanged.

[REV-015] · medium · resolved · valid · blocks:yes — A { body after for NAME, select NAME or function NAME, and coproc, keep the body's first command inside the keyword's segment

Unchanged; test_rev015_* pass at cca777c.

[REV-016] · medium · resolved · valid · blocks:yes — A quoted reserved word after coproc NAME is read as a compound keyword, so the coprocess program is dropped and its guards are skipped

scripts/stage_permissions.py (_shell_segments, _peel_command_headers/_peel_one_header, _shell_identity), tests/test_consent_variants.py, docs/host-permissions.md. Fix commit cca777c.

Reproduced before editing. The new tests were written first and run at a1c0dc0 plus the tests only. For every quoted form, disposable Bash with a stubbed find ran the coprocess program, while the real stage_permissions.py hook subprocess allowed the protected find … -delete under the .+ compound grant: test_rev016_bash_baseline_and_real_hook_allow_and_deny failed with False != True.

Cause. finish_word removes quotes before a word is stored, but Bash recognises reserved words and comments before quote removal. The same loss of quoting had four more effects:

  • An empty quoted word ("") was dropped, so coproc find "" if src -delete also hid find.
  • printf x > ""; git push … took git as the redirect target and hid git push from its guard. Found by the delegated review.
  • ""# started a "comment", which hid every later command.
  • ""~ expanded to $HOME.

Fix.

  • _shell_segments records per-word quoting (quote characters, backslash escapes and $'…'; a backslash-newline is not quoting).
  • It keeps empty quoted words as words or redirect targets.
  • It does not start a comment or a tilde expansion after a quoted prefix.
  • It treats a quoted digit before > as an argument.
  • _peel_command_headers treats words[2] as a compound keyword after coproc NAME only when it is unquoted. Peeling a quoted leading word stays conservative, because that only exposes more words to the guards.
  • _shell_identity skips empty operands, so a "" argument does not garble the consent identity.

Verified by execution:

  • test_rev016_quoted_reserved_words_keep_the_coprocess_program covers 14 quoted spellings ("if", 'if', \if, i""f, $'if', "{", '{', \{, '[[', "while", "until", "for", "select", "case") × 4 forms (coproc …; wait, inside "$(…)", time coproc, ! coproc), plus the ""/'' and ""# forms. Each runs with find src -delete and find src -exec rm -rf {} +, under Claude/Codex × resolve/rereview with the .+ grant. Each one yields a find segment, a protected_reason naming find, a check() denial and no refused_operation.
  • test_rev016_bash_baseline_and_real_hook_allow_and_deny: Bash runs every form. The real hook denies each one with [layer=toolkit_hook], and allows the printf counterpart under exact consent.
  • test_rev016_unquoted_reserved_words_still_name_the_coprocess: unquoted if/{/[[/case and i\<newline>f still name the coprocess.
  • test_rev016_quoted_words_keep_redirect_and_tilde_meaning: the descriptor, ""~ and > "" cases, including a Bash baseline showing that git runs after the failed redirect.

All pass (Ran 58 tests — OK).

Post-change review and security

  • Delegated cc-code-review + cc-security-review on a1c0dc0.. the fix:
    • No P0 or P1 findings.
    • The peel refactor keeps the flags aligned with the words and always terminates.
    • _heredoc_substitutions [:-1] stays correct, and is now safer for empty bodies.
    • Two same-cause items were raised and fixed in this commit: ""~ expansion (P2), and the missing > "" and descriptor tests (P2/P3). The _shell_identity empty-operand nit (P3) was fixed as well.
    • Left as is (P3, conservative): the !( negation check calls _peel_command_headers without quoting flags, which can only peel more.
  • Security triage: the mandatory minimum did not fire, because only scripts/, tests/ and docs/ changed and the PR has no labels. The runtime plan sets security_required: true, so the audit ran. No vulnerability was introduced. One pre-existing bypass (> "" hiding the next program) is now closed and pinned by a test.
  • Residual risk, potential, not new: a symlink created earlier in the same compound command (ln -s / x; cat x/home/…) is not resolved by the static analysis, because it does not exist when the command is checked. External sandbox isolation remains the second layer. security_audit_ran=true.

Verification — agent-reported, tests.version=2

Run in this stage's worktree at cca777c (the tree identical to the commit), in the foreground. Logs are in $TMPDIR/<check>.log.

Status: REVIEW_PASSED_AWAITING_CI on head cca777c7d8add43729f42734de0b25b61bed783b. The review of this head is complete, and no open finding blocks approval. REV-016 is fixed and verified by execution. REV-014, which the runtime named as contested, passes its full regression matrix at this head. No new findings. This is not an approval: all six code-host checks pass, but the two required native parity checks (AC-8) have not run, so verification is not_verified and the cycle's gate decides.

Changes since the previous rereview (a1c0dc0 → cca777c)

  • scripts/stage_permissions.py:
    • _shell_segments records whether each word had any quoting ("…", '…', \x, $'…'; a backslash-newline does not count). It keeps empty quoted words as words or redirect targets. It does not start a comment or tilde expansion after a quoted prefix, and it reads a quoted digit before >/< as an argument.
    • _peel_command_headers is split into _peel_one_header, and the quoting flags move with the peeled prefix. The named-coproc rule now requires words[2] to be unquoted.
    • _shell_identity skips empty operands.
  • tests/test_consent_variants.py: four test_rev016_* tests (14 quoted spellings × 4 forms, empty-word and ""# forms, Bash baseline, real hook subprocess, unquoted negatives, redirect and tilde meaning).
  • docs/host-permissions.md: documents the quoting rule.

The accumulated diff file was confirmed at 4133 lines (origin/main...cca777c, merge base f22fc1df8d07bce22be8ac519a60b89a3b5a8eb0, 19 files). The delta (git diff --stat: 3 files, +185/−25) was read in full, along with the current _shell_segments tokenizer, finish_word/finish_segment, _heredoc_substitutions, _shell_identity and the find branch of protected_reason. The SHA-256 was not recomputed: sha256sum is not in this stage's command table. Trusted history (author datacas): REV-001–REV-016, with no gaps or ID collisions.

[REV-009] · medium · resolved · valid · blocks:yes — Tilde prefixes ~user, ~+ and ~- are expanded as ~, so the credential guard checks the wrong path

[REV-010] · low · resolved · valid · blocks:no — The env -C guard applies only when env is the program word, so command env -C "$X" and wrapped forms get past it

[REV-014] · medium · resolved · valid · blocks:yes — A case pattern's ) inside $(…) ends the substitution early, so later commands are hidden from the segment guards

Contested; checked again by execution at this head. In this stage's clone at cca777c, test_rev014_case_patterns_do_not_end_substitutions, test_rev014_bash_fixture_runs_the_command_after_the_pattern and test_rev014_safe_cases_get_consent_and_real_hook_retains_guards all pass, as part of issue-439-regression (Ran 58 tests — OK, nothing skipped). They cover REV014_FORMS, REV014_LOOP_FORMS, REV014_TIME_FORMS and REV014_EXTGLOB_FORMS. The Bash fixture shows that the hidden command runs, and the real hook denies it.

The delta does not touch _shell_keyword or _shell_expansion_end, which track case…esac by source offset. Quoting only changes how words are classified after tokenization. Status stays resolved, and the disposition is unchanged.

[REV-015] · medium · resolved · valid · blocks:yes — A { body after for NAME, select NAME or function NAME, and coproc, keep the body's first command inside the keyword's segment

Still resolved: test_rev015_* pass at this head. The peel refactor keeps the same header set and order. Each _peel_one_header call removes a prefix only, so slicing flags[before - len(words):] keeps the flags aligned with the words, and the loop stops as soon as nothing is peeled.

[REV-016] · medium · resolved · valid · blocks:yes — A quoted reserved word after coproc NAME is read as a compound keyword, so the coprocess program is dropped and its guards are skipped

scripts/stage_permissions.py:828-874 (_peel_command_headers, _peel_one_header), :877-1079 (_shell_segments).

Corrected and verified by execution. These tests ran in this stage's clone at cca777c and pass:

  • test_rev016_quoted_reserved_words_keep_the_coprocess_program: 14 quoted spellings ("if", 'if', \if, i""f, $'if', "{", '{', \{, '[[', "while", "until", "for", "select", "case") × the forms coproc …; wait, inside "$(…)", time coproc and ! coproc, plus the ""/'' empty-word and ""# forms. Each runs with find src -delete and find src -exec rm -rf {} +, under Claude/Codex × resolve/rereview with the .+ compound grant. Each one yields a find segment, a protected_reason naming find, a check() denial and no refused_operation. This is the exact form the previous rereview reported (coproc find "if" src -delete) and its "{"/\while/"[["/$(…) variants.
  • test_rev016_bash_baseline_and_real_hook_allow_and_deny: disposable Bash with a stubbed find runs every form. A real stage_permissions.py hook subprocess denies each one with [layer=toolkit_hook] and allows the printf counterpart under exact consent.
  • test_rev016_unquoted_reserved_words_still_name_the_coprocess: unquoted if/{/[[/case and i\<newline>f still treat worker as the coprocess name.
  • test_rev016_quoted_words_keep_redirect_and_tilde_meaning: "2">f is an argument with a stdout redirection, ""~ stays literal, and > "" no longer swallows the next program (git push --force keeps its guard, with a Bash baseline).

Static review of the fix:

  • word_quoted is reset only in finish_word. The one direct word = [] (the numbered descriptor) runs only when the word is unquoted.
  • quoted_words is appended in step with words and cleared in finish_segment.
  • Substitutions and $HOME/$TMPDIR splices do not set the flag, which matches Bash: an expansion is not quoting.
  • _shell_identity builds its identity from the shell source. Skipping "" only stops Path(cwd) / "" from naming cwd, which would otherwise place a <TMPDIR> placeholder when cwd is the TMPDIR.

Security triage and audit

The deterministic minimum did not fire: none of the 19 changed paths is a CI, secret or agent-configuration path, and the PR has no labels. The runtime plan sets security_required: true, and the change is to the permission parser, so cc-security-review ran as a delegated pass on the delta and on its effect on the segment guards.

  • Confirmed vulnerabilities in the delta: none.
  • Reviewed, no issue found:
    • Quoting only reduces header peeling at coproc NAME. Everywhere else a quoted leading word is still peeled, which only exposes more words to the guards.
    • Keeping empty quoted words consumes a pending redirect target, which closes the earlier > ""; git push gap.
    • Not starting a comment after "" makes the parser analyse more text, not less.
    • A literal ""~ cannot name the home store.
    • _heredoc_substitutions [:-1] still drops only the outer quoted word, also for an empty body.
    • The !( negation check still peels without flags. That can only peel more and is conservative.
  • Potential risk, not a delta finding: guards compare the words the parser can see, not runtime filesystem state. An unquoted glob in a consented compound segment can expand to option-like file names (for example a file named -delete turning find src * into find src … -delete). That is the same class as the symlink residual the resolver recorded (ln -s / x; cat x/home/…). The consent question already warns that shell internals need external isolation. A follow-up could treat an unquoted glob operand of find/git/gh as possibly option-forming. This was static reasoning only: probes of parse_command and Bash are outside this stage's command table.

Permissions

The stage command table refused two accessory operations, and neither was bypassed:

  • gh pr view 468 --repo datacas/code-cycle-toolkit --json comments --output … (command_0113db488cdff808b07eccaa49b890216de9ee7a77b0a926fb24ac471a02d9b4). A redirect into $TMPDIR replaced it.
  • A --jq filter with a double-quoted $i (refused_204c5677c74e5bbf2eda734bee6473291381bd66552530525ad80d13e5fc18e8). A single-quoted filter replaced it.

No check was affected.

Residual risk and verdict

The static Bash model now keeps quoting for reserved words, comments, tildes, descriptors and empty words. What remains is runtime state that no static analysis can see (glob expansion to option-like names, symlinks created in the same command), together with the documented wrapper/interpreter trust. External sandbox isolation is the second layer.

Verdict: REVIEW_PASSED_AWAITING_CI. No finding blocks approval. Approval waits on the required native parity checks (AC-8), which the cycle's gate decides.

Status: CHANGES_REQUESTED on head cca777c7d8add43729f42734de0b25b61bed783b. REV-001–REV-016 stay resolved, and their regression suite passes again at this head. Two new findings block approval. Issue #439 gained two acceptance criteria at 2026-11-10T13:55Z, after the previous rereview (CCR-20261110-005): AC-13, for the session's tool-results directory, and AC-14, for the scope offered for an unmatchable grant. This head implements neither.

Changes since the previous rereview

The accumulated diff file was confirmed at 4133 lines (origin/main...cca777c, merge base f22fc1df8d07bce22be8ac519a60b89a3b5a8eb0). The head is unchanged, so this pass checked the two new criteria against the current source (scripts/stage_permissions.py, scripts/grants.py, docs/, tests/) and reran every frozen check. Trusted history (author datacas): REV-001–REV-016, with no gaps or ID collisions. New IDs start at REV-017.

Still resolved: the test_rev015_* tests pass at this head.

[REV-016] · medium · resolved · valid · blocks:yes — A quoted reserved word after coproc NAME is read as a compound keyword, so the coprocess program is dropped and its guards are skipped

Still resolved: the test_rev016_* tests pass at this head.

[REV-017] · medium · open · - · blocks:yes — Reads under the stage session's own Claude tool-results directory are still outside the workspace, so every new dispatch asks again (AC-13)

scripts/stage_permissions.py:1371-1378 (read branch of _check_words), scripts/stage_permissions.py:2641 (prompt_note).

A read operand is accepted only when it lies under the stage cwd, under a policy.evidence_paths entry or under $TMPDIR. Otherwise it raises reading outside the stage workspace needs operation consent. No code at this head knows about ~/.claude/projects/<tmp-review-dir>/<session-uuid>/tool-results/: git grep -i tool-results over scripts/, docs/ and skills/ finds nothing. The operand also keeps its per-session absolute path, so a grant never matches in a later dispatch. prompt_note does not tell the reviewer to read large outputs in smaller pieces or to write them under $TMPDIR.

Reproduced in this stage: Claude Code saved a large grep output to /home/datacas/.claude/projects/-tmp-code-cycle-review-nbecydti/<session-uuid>/tool-results/budy32eb9.txt. The follow-up grep -c "" <that file> was refused with reading outside the stage workspace needs operation consent (command_9ff1d7d8…, rule command_table). The refusal came from the installed runtime hook, which follows the same rule as this head. This is the exact loop the 2026-11-10 feedback describes.

Required by AC-13:

  • treat the current session's tool-results directory as a placeholder, like $TMPDIR, resolved against symlinks and real membership, so a grant from an earlier dispatch of the same stage matches;
  • keep another session's directory outside that placeholder, so it still asks;
  • add the prompt-note sentence.

AC-14 asks for regression tests for the same-stage later-dispatch case and the other-session case.

[REV-018] · medium · open · - · blocks:yes — A grant for a path unique to one dispatch or session is still offered as persistent/forever, and the question does not say it can never match again (AC-14)

scripts/grants.py:111-113 (command_options), scripts/grants.py:325-355 (refusal_question).

refusal_question always offers command_options(role), which is this cycle / this repository / forever / deny (without forever for review/rereview). That depends only on the role, never on the operand. A grant whose operand names a session tool-results file, or another dispatch's temporary path, therefore gets this repository and forever. Those answers are stored under a command_<sha256> identity that no later dispatch can produce. The prompt text gives no reason for any restriction. The refusal in this stage offered "this cycle / this repository / forever / deny" for the tool-results path above. AC-14 asks to offer only cycle scope or a pattern grant for such operands, to explain why in the question, and to add a regression test for the offered scope.

Security triage and audit

The deterministic minimum did not fire: none of the 19 changed paths is a CI, secret or agent-configuration path, and the PR has no labels. The runtime plan sets security_required: true, and the change is to the permission hook, so cc-security-review ran as a delegated pass.

  • Confirmed vulnerabilities: none. No code changed since the last audit (CCR-20261110-005). This pass rechecked the read-outside-workspace branch and the consent-scope code that REV-017 and REV-018 concern.
  • For the fix of REV-017: the tool-results allowance must cover only the current session's directory, resolved with realpath and real membership (no prefix string match, and no .. or symlink escape). The other sessions' directories under ~/.claude/projects/ hold transcripts and outputs of unrelated work, possibly from other repositories, so a broader placeholder would turn a same-session convenience into a cross-session read.
  • REV-018 is a usability and hygiene gap, not an exploit: grants that can never match pile up in consents.json.
  • Residual (unchanged from the last audit): the guards see words, not runtime filesystem state. Glob expansion to option-like names and symlinks created inside the same command are left to external isolation.

security_audit_ran=true.

Permissions

The stage command table refused two accessory operations, and neither was bypassed:

  • grep -c "" <session tool-results file> (command_9ff1d7d8048218cdac666d4b15828cb00c84bd4d15f9922e80ab59daf613c5b8). The native Read tool read the file instead. This is evidence for REV-017.
  • grep -o -E … comments.json > $TMPDIR/headers.txt (command_a2722f9ed5c9a670d449f8df132135002db90e5f20dd46090b68a03b10a323c3, "grep may not redirect its output"). It was not needed.

No check was affected.

Residual risk and verdict

The parser and guard work behind REV-001–REV-016 is stable and verified at this head. What is missing is the session tool-results handling and the scope rule for unmatchable grants, which the issue now requires. The issue cites this unattended-rereview loop as the reason for those criteria, and it reproduced in this very stage.

Verdict: CHANGES_REQUESTED. Blocking findings: REV-017 and REV-018.

… unique paths (#439)

REV-017 (AC-13): the hook takes the current Claude session's tool-results
directory from the host event (session_id + transcript_path). Read-table
commands under it are allowed like $TMPDIR reads; other operations name the
operand <TOOL_RESULTS>/<OUTPUT>, so a grant from an earlier dispatch of the
same stage matches. Membership uses real paths; another session's directory
stays literal and still asks. The prompt note tells the agent to read large
outputs in smaller pieces or under $TMPDIR.

REV-018 (AC-14): an exact operation that still names a dispatch- or
session-unique path is offered "this cycle / deny" only, with the reason in
the question; a persistent or forever answer is kept for this cycle and noted.
…439)

- the runtime accepts COMMAND_PERMISSION_TOOL_RESULTS only in the
  .../projects/<dir>/<session>/tool-results shape, as the hook does;
- a tool-results directory that is a symlink covers nothing;
- a bare `~` in shell source normalizes to the same placeholder;
- the dispatch-unique path regex is linear and also ends at `:`, `,`,
  `]`, `}` and `=` (Docker mounts, option lists);
- a `--grant` persistent/forever answer for a unique operation reports
  the cycle answer it was kept as;
- the question says the placeholder matches any saved output, and the
  scope note precedes the configured-command detail.

Status: RESOLVED on head c83bf6b858ff730998382e893db5c9b0375c366e (previous head cca777c7d8add43729f42734de0b25b61bed783b). REV-017 and REV-018 (AC-13 and AC-14) are fixed with regression tests. REV-014, named as contested by the runtime, does not reproduce at the triage commit, so it stays resolved. Required native parity checks for AC-8 remain unverified, so verification is not_verified.

Triage ran before any edit, against cca777c. REV-017 and REV-018 are valid: both name criteria the work item added at 2026-11-10T13:55Z, and the triage commit implements neither. Every earlier disposition stays as published. The accumulated diff file (origin/main...cca777c, 4133 lines) was used as triage context.

[REV-014] · medium · resolved · valid · blocks:yes — A case pattern's ) inside $(…) ends the substitution early, so later commands are hidden from the segment guards

The runtime named this finding as contested, because the rereview of 48b3c0f reopened it after an earlier fix. Before editing, this stage reproduced it with that rereview's own forms at the triage commit cca777c:

  • printf '%s' "$(for ((;;)) do case a in a) git push --force origin main ;; esac; break; done)";
  • "$(set -- 1; for x do case a in a) git push --force origin main ;; esac; done)";
  • the same forms with cat ~/.ssh/id_rsa, and the select NAME do, for ((…)) { …; } and continuation variants.

All of them are in REV014_LOOP_FORMS (tests/test_consent_variants.py). python3 -m unittest tests.test_consent_variants -k rev014 ran 4 tests and passed. The tests check that parse_command yields a separate git push segment, that protected_reason refuses it, that the real hook refuses it with [layer=toolkit_hook], and that a disposable-Bash baseline really runs the hidden command. The cause the rereview identified (do/{ after a for/select header was not taken as command position) was fixed in 16ded03/a1c0dc0, and CCR-20261110-005 and CCR-20261110-006 already confirmed this. The status stays resolved on that evidence. This is not a new not_applicable claim, and the disposition stays frozen.

[REV-017] · medium · resolved · valid · blocks:yes — Reads under the stage session's own Claude tool-results directory are still outside the workspace, so every new dispatch asks again (AC-13)

Reproduced at cca777c with the reviewer's case. The read branch of _check_words accepted only cwd, evidence_paths and $TMPDIR, and nothing named the session's tool-results directory. Cause: the hook did not know the session at all. Claude Code sends session_id and transcript_path in every hook event, and the tool-results directory sits beside that transcript.

Fix (scripts/stage_permissions.py, scripts/command_permissions.py, scripts/executors.py, scripts/grants.py):

  • session_tool_results() derives the directory only from the host event. It requires transcript_path named <session_id>.jsonl and the shape …/projects/<project-dir>/<session_id>/tool-results. _hook_main sets it on the policy per event; the stored policy never carries it.
  • inside_tool_results() uses the same real-path membership rule as $TMPDIR: symlinks, .. and a bare ~ are resolved first. A tool-results directory that is itself a symlink covers nothing.
  • A read-table command (grep, cat, wc, …) under that directory is allowed like a $TMPDIR read, so it asks no question in any dispatch. Every other operation names the operand {"tool_results": "<OUTPUT>"}, or <TOOL_RESULTS>/<OUTPUT> in shell source. A grant from an earlier dispatch of the same stage therefore matches the output of the later session. Another session's directory stays literal and still asks.
  • The hook reports the directory as COMMAND_PERMISSION_TOOL_RESULTS. The runtime accepts that marker only in the same shape, so the consent identity matches the hook's.
  • prompt_note now tells the agent to read large outputs in smaller pieces or to write them under $TMPDIR.

Verification: the new tests run the real hook with host-shaped events for two sessions and two dispatches, in resolve and rereview:

  • grep -c "" <own output> and grep -n -E … need no question;
  • another session's output still asks;
  • a symlink out of the directory still asks;
  • a grant given for grep … | head or wc … > $TMPDIR/… in dispatch 1 lets dispatch 2 run the same command on its own session's output with no question.

The tests are test_ac13_* and test_ac13_ac14_*, all passing.

[REV-018] · medium · resolved · valid · blocks:yes — A grant for a path unique to one dispatch or session is still offered as persistent/forever, and the question does not say it can never match again (AC-14)

Reproduced at cca777c. command_options() depended only on the role, so the reviewer's tool-results refusal was offered this cycle / this repository / forever / deny.

Fix:

  • stage_permissions.dispatch_unique_path() finds a literal path that is still unique after normalization: another session's tool-results directory, another dispatch's code-cycle-tmp-*, or a code-cycle-review-* clone. The regex is linear and ends at /, whitespace, quotes, :, , and brackets.
  • For such an operation refusal_question offers only this cycle / deny and says why, before the generic text. A pattern grant stays available as an edited answer. The permission record carries dispatch_unique_path.
  • apply_answer keeps a persistent or forever answer for such an operation as a cycle answer and notes it. It never refuses and never saves it for the repository. _resolve now reports the answer that was actually applied.
  • The question also states that <TOOL_RESULTS>/<OUTPUT> matches any saved output of the current session.

Verification: test_ac14_dispatch_unique_operands_are_offered_this_cycle_only covers four unique operands and two ordinary ones, in both roles, including the stored answers and an empty repository store. test_ac13_ac14_edges_* covers ~ operands, Docker -v mounts, option lists, spoofed markers, a symlinked root and the --grant path.

Post-change review and security

  • Delta base: cca777c7d8add43729f42734de0b25b61bed783b, the latest trusted rereview receipt. git merge-base --is-ancestor confirmed it is an ancestor of the new head.

  • cc-code-review (delegated, fix delta): no P0 or P1 findings. This round fixed the P2 items it raised: the --grant answer, ~ operands, regex boundaries and cost, marker shape, a symlinked root, and the question wording. Its design note is left as is: absolute review-clone operands for programs other than Docker stay literal, and they are now offered for this cycle only.

  • cc-security-review (delegated, final delta): no confirmed vulnerabilities. It found three low potential risks:

    • A forged COMMAND_PERMISSION_* marker in agent-printed error output can cause a spurious question. The hook still matches only the real directory. The same channel already exists for TMPDIR and OPERATION.
    • A repository grant for an interpreter running <TOOL_RESULTS>/<OUTPUT> runs any saved output. The question now warns about this, with the same exposure as <TMPDIR>/x.
    • Placeholder text can match lexically for regex grants. The agent cannot write under ~/.claude/projects.

    One docstring overstated a check; it was corrected in c83bf6b.

  • Deterministic security minimum: it did not fire. No CI, secret or agent-configuration path changed. The audit ran because the plan sets security_required: security_audit_ran=true.

  • Docs: docs/host-permissions.md (Reusable command consent and When a command is denied) and the PA-43 row in docs/capability-parity-audit.md describe the new behaviour. docs/ROADMAP_V2.md needs no change, because no issue or milestone changed in this round.

Verification — agent-reported, tests.version=2

The frozen checks owned by codex ran here under the Claude resolve dispatch. Their identities are kept unchanged.

Conclusion: not_verified. AC-8's native baselines did not run. Every other criterion, AC-13 and AC-14 included, has passing linked coverage.

Environment: the local run uses the toolkit's own temporary directories and the Python 3.10 interpreter of this host. Tests that create commits set their own identity. CI runs Windows shards that this host does not.

CI (head c83bf6b, read once; parallel policy)

No check had reported on the pushed head when it was read: 0 passed, 0 failed, 0 reported pending. The six checks expected from earlier heads are not reported yet: Skills, manifests, and Bash installer, PowerShell installer and Windows test shard (windows-1…4). The cycle's CI gate decides on them.

Residual risk

  • The static Bash model is still not a full grammar (REV-001–REV-016 history).
  • The tool-results allowance trusts the host's hook event and Claude Code's directory layout. A custom CLAUDE_CONFIG_DIR keeps the projects/ layout and is covered. A different layout falls back to the ordinary consent question.

Status: REVIEW_PASSED_AWAITING_CI on head 770e6ebb5162ca5054bd602ca056e7e580e60e27 (previous reviewed head cca777c7d8add43729f42734de0b25b61bed783b). The review of this head is complete. No open finding blocks approval. This is not an approval: required CI checks are still pending, and the cycle's CI gate decides. One new low, non-blocking finding (REV-019).

What changed since the previous review

The accumulated diff origin/main...770e6eb (4698 lines; merge base c1f6265) was the diff under review. Its line count was confirmed. The fix delta was read in full.

Those cases cover the for ((;;)) do, for x do, select … do, { …; } and continuation forms, and they include a real-hook refusal and a disposable-Bash baseline. The fix delta does not touch the parser.

[REV-015] · medium · resolved · valid · blocks:yes — A { body after for NAME, select NAME or function NAME, and coproc, keep the body's first command inside the keyword's segment

Still resolved. test_rev016_* passes.

[REV-017] · medium · resolved · valid · blocks:yes — Reads under the stage session's own Claude tool-results directory are still outside the workspace, so every new dispatch asks again (AC-13)

Verified resolved. issue-439-session-outputs ran and passed (6 tests). The tests drive the real hook with host-shaped events across two sessions and two dispatches, in resolve and rereview. The code was also checked by reading:

  • session_tool_results derives the directory only from session_id and a transcript_path named <session_id>.jsonl.
  • _hook_main always overrides any stored tool_results with that value.
  • inside_tool_results applies real-path membership and refuses a symlinked root.
  • Another session's directory stays literal.

The live observation in this stage does not count against the fix. The installed runtime hook refused grep -c … <this session's tool-results file>, but its message carries no COMMAND_PERMISSION_TOOL_RESULTS marker, so that hook predates this branch.

[REV-018] · medium · resolved · valid · blocks:yes — A grant for a path unique to one dispatch or session is still offered as persistent/forever, and the question does not say it can never match again (AC-14)

Verified resolved. test_ac14_dispatch_unique_operands_are_offered_this_cycle_only and test_ac13_ac14_edges_* pass. By reading the code:

  • command_options(unique_path=…) returns ["this cycle", "deny"].
  • apply_answer narrows persistent and forever to cycle before anything is stored. Command grants are isolated_per_dispatch=True, so the narrowed answer is never refused.
  • _resolve reports the answer it actually applied.
  • The question states why only these scopes are offered, before the generic text.

[REV-019] · low · open · - · blocks:no — The new detail[:120] cut truncates a configured command longer than 98 characters in the consent question (AC-2)

scripts/grants.py:374: refusal_question now builds …{scope_note}{detail[:120]}…. Here detail is " Configured command: " + configured + ".". Before this delta, detail was inserted whole, and only the overall 600-character cut applied. That left roughly 375 characters for the configured command when no unique-path note is present.

The new cut leaves 98 characters. Any allowed_commands.test or verify longer than that is named only partially in the question, for example docker compose -f docker-compose.test.yml run --rm --no-deps app php artisan test --parallel --processes=4 --testsuite=Unit (118 characters). AC-2 requires the question text to name the exact configured command, so the agent can retry with it.

Evidence: the expression is deterministic, so this follows from reading it. A probe test was not executed, because this stage's edit rule refuses helper files in $TMPDIR other than the comment, report and log files. The existing test (tests/test_consent_variants.py:81) uses pnpm run test:unit, which is shorter than the cut.

Suggested fix: keep the configured command whole, and shorten command[:140] or the generic text instead. Alternatively, move detail ahead of scope_note. Add a test with a configured command longer than 98 characters.

Security

  • Triage: the deterministic minimum did not fire, because no CI, secret or agent-configuration path changed. The change does alter the toolkit's own permission and consent boundary, and the plan sets security_required, so cc-security-review ran as a delegated pass on the accumulated diff, focused on the fix delta: security_audit_ran=true.
  • Confirmed vulnerabilities: none.
  • Reviewed:
    • The session directory comes only from the host hook event, and a stored policy value is always overwritten.
    • The read allowance uses real-path membership, excludes the directory itself, and refuses a symlinked root. The agent cannot write under ~/.claude/projects in this sandbox.
    • The _DISPATCH_UNIQUE_PATH regex is linear: the components exclude /, and the lookbehind has a fixed width of one character.
    • The persistent→cycle change only narrows a scope.
    • The COMMAND_PERMISSION_TOOL_RESULTS marker is accepted only in the …/projects/<dir>/<session>/tool-results shape.
  • Potential risks (low, already disclosed by the resolver's audit):
    • A forged marker in agent-printed output could make the runtime's refusal reconstruction match a grant. The hook still decides at execution time from the real event.
    • A repository grant for an interpreter running <TOOL_RESULTS>/<OUTPUT> runs any saved output, whose content may be untrusted. The question warns about this.
    • The literal placeholder text matches lexically, but it resolves to a harmless relative path.
  • Not reviewed: Claude Code's own permission layer and the transcript_path semantics of future Claude Code versions. A different layout falls back to the ordinary question.

Status: REVIEW_PASSED_AWAITING_CI on head 770e6ebb5162ca5054bd602ca056e7e580e60e27 (previous reviewed head 770e6ebb5162ca5054bd602ca056e7e580e60e27, CCR-20261110-007). The review of this head is complete, and no open finding blocks approval. This is not an approval. Two required CI checks of this head have failed (see CI), and the cycle's CI gate decides on them.

What changed since the previous review

Nothing. The head is the same commit that CCR-20261110-007 reviewed. This run belongs to a new cycle plan (plan-cycle-fe438123…, revision 4), so the review was repeated in full on the current head. Every local check was run again.

The accumulated diff origin/main...770e6eb (4698 lines, merge base c1f6265) was the diff under review. Its line count was confirmed. Its SHA-256 could not be recomputed, because sha256sum is outside this stage's table. Every source and documentation hunk was read: scripts/grants.py, scripts/stage_permissions.py, scripts/command_permissions.py, scripts/cycle.py, scripts/executors.py, scripts/user_choices.py, docs/host-permissions.md, docs/configuration.md, docs/capability-parity-audit.md, docs/ROADMAP_V2.md and the JSON manifests. The test files were covered by executing them, not by reading every line.

Findings

[REV-001] · high · resolved · valid · blocks:yes — Regex grants match raw compound shell source, so a simple-command pattern authorizes other segments

Still resolved: pattern_covers_operation requires compound: true for <SHELL> operations. issue-439-regression passes at this head (64 tests).

[REV-002] · medium · resolved · valid · blocks:yes — The segment credential guard compares literal paths, so cd options, pushd and globs get past it

Still resolved. issue-439-regression passes.

[REV-003] · medium · resolved · valid · blocks:no — Every consent question names the configured test command, even for unrelated commands

Still resolved. A configured command is named only when the program word matches. issue-439-regression passes.

[REV-004] · medium · resolved · valid · blocks:no — An invalid edited pattern, or forever for review, ends the whole cycle instead of asking again

Still resolved. The interactive loop in ConsentBroker asks again with validation_error. issue-439-regression passes.

[REV-005] · low · resolved · valid · blocks:no — The "Codex" AC-8 parity test does not exercise Codex

Still resolved at test level. The native Codex baseline itself remains unverified (see Verification).

[REV-006] · medium · resolved · valid · blocks:yes — A relative argument after cd "$VAR" is refused with no consent question, even when it is not a path

Still resolved. issue-439-regression passes.

[REV-007] · low · resolved · valid · blocks:no — Glob credential matching lets * cross /, so unrelated absolute globs count as credential reads

Still resolved. issue-439-regression passes.

[REV-008] · medium · resolved · valid · blocks:yes — builtin cd, command cd and CDPATH still get past the segment credential guard

Still resolved. issue-439-regression passes.

[REV-009] · medium · resolved · valid · blocks:yes — Tilde prefixes ~user, ~+ and ~- are expanded as ~, so the credential guard checks the wrong path

Still resolved. issue-439-regression passes.

[REV-010] · low · resolved · valid · blocks:no — The env -C guard applies only when env is the program word, so command env -C "$X" and wrapped forms get past it

Still resolved. issue-439-regression passes.

[REV-011] · medium · resolved · valid · blocks:yes — CDPATH, HOME, OLDPWD, dotglob and GLOBIGNORE are detected in the raw source, so continuations and quoting the parser decodes hide them

Still resolved. issue-439-regression passes.

[REV-012] · medium · resolved · valid · blocks:yes — Glob options other than dotglob are not modelled, so nocaseglob lets a differently cased glob reach a store

Still resolved. issue-439-regression passes.

[REV-013] · medium · resolved · valid · blocks:yes — The extglob tokenizer counts parentheses inside ${…} and $[…], so it folds the commands after an extglob into one operand

Still resolved. issue-439-regression passes.

[REV-014] · medium · resolved · valid · blocks:yes — A case pattern's ) inside $(…) ends the substitution early, so later commands are hidden from the segment guards

Still resolved. The REV014_LOOP_FORMS cases in issue-439-regression pass at this head.

[REV-015] · medium · resolved · valid · blocks:yes — A { body after for NAME, select NAME or function NAME, and coproc, keep the body's first command inside the keyword's segment

Still resolved. issue-439-regression passes.

[REV-016] · medium · resolved · valid · blocks:yes — A quoted reserved word after coproc NAME is read as a compound keyword, so the coprocess program is dropped and its guards are skipped

Still resolved. issue-439-regression passes.

[REV-017] · medium · resolved · valid · blocks:yes — Reads under the stage session's own Claude tool-results directory are still outside the workspace, so every new dispatch asks again (AC-13)

Still resolved. issue-439-session-outputs passes again at this head (6 tests). _hook_main takes the directory only from session_tool_results(event). inside_tool_results uses real-path membership and refuses a symlinked root.

[REV-018] · medium · resolved · valid · blocks:yes — A grant for a path unique to one dispatch or session is still offered as persistent/forever, and the question does not say it can never match again (AC-14)

Still resolved. issue-439-session-outputs passes. command_options(unique_path=…) offers this cycle / deny, and apply_answer narrows persistent/forever to cycle.

[REV-019] · low · open · - · blocks:no — The new detail[:120] cut truncates a configured command longer than 98 characters in the consent question (AC-2)

Still reproducible, because the head is unchanged. scripts/grants.py:374 still builds …{scope_note}{detail[:120]}…, where scripts/grants.py:355 sets detail = " Configured command: " + configured + ".". A configured command longer than 98 characters is therefore named only partially, and AC-2 asks for the exact command. Low and non-blocking: the full command is still in the permission record that goes with the question. Suggested fix: keep detail whole and shorten another part, then add a test with a configured command longer than 98 characters.

No new findings.

Security

  • Triage: the deterministic minimum did not fire, because no CI, secret or agent-configuration path changed. The change alters the toolkit's own permission and consent boundary, and the plan sets security_required, so cc-security-review ran as a delegated pass on the accumulated diff: security_audit_ran=true.
  • Confirmed vulnerabilities: none.
  • Reviewed:
    • Session tool-results allowance: the directory comes only from the host event (session_id plus <session_id>.jsonl). The membership check resolves symlinks and .., and a symlinked root covers nothing.
    • COMMAND_PERMISSION_TOOL_RESULTS marker: shape-validated in _observed_policy, and used only for runtime reconstruction; the hook decides at execution time.
    • Regex grants: structural validation (nested repetition, alternation under repetition, backreferences and lookarounds are rejected) and an isolated python3 -I subprocess with a 500 ms budget and no shell.
    • Pattern matching lifts only table membership: protected_reason runs first.
    • The persistent/forever → cycle change only narrows a scope.
    • The credential guard over compound segments, directory changes and globs.
    • Bash(*) host allow for pattern, check or shell grants: documented, and the hook stays the concrete gate.
  • Potential risks (low, already disclosed):
    • A repository grant for an interpreter run on <TOOL_RESULTS>/<OUTPUT> executes whatever saved output matches, and that content may be untrusted. The question warns about this.
    • The static Bash model is not a full grammar.
  • Not reviewed: Claude Code's own permission layer and future transcript_path layouts. A different layout falls back to the ordinary question.

Verification — agent-reported, tests.version=2

The codex-owned checks ran under this Claude rereview dispatch, and their identities are kept unchanged.

Conclusion: not_verified. AC-8's native baselines did not run. AC-15–AC-26 have no linked frozen check, so they remain open.

  • sha256sum <accumulated.diff> (command_table).
  • gh run view 42844102533 --repo datacas/code-cycle-toolkit --job 129926806839 --log-failed > $TMPDIR/… (command_table): the failure log of the Windows shard was not read.

Windows test shard (windows-2) pass (11m12s)
Windows test shard (windows-3) fail (18m52s)
Windows test shard (windows-4) pass (16m6s)
PowerShell installer fail (3s)

4 passed, 2 failed, 0 pending. windows-3 runs test_consent_variants, which this PR adds. These failures are reported here, not as findings: the cycle's CI gate turns them into work or a stop. The local Linux run of the same modules passes.

Residual risk and verdict

  • The static Bash model is still not a full grammar (see the REV-001–REV-016 history).
  • The tool-results allowance relies on Claude Code's hook event and directory layout.
  • AC-8 native parity and AC-15–AC-26 have no executed evidence.
  • Two required CI checks fail at this head.
  • Project verdict: no blocking finding is open, and REV-019 is low and non-blocking. The review of this head is complete. Approval waits for the CI gate, which currently sees two failed checks.

…root (#439)

A rooted path without a drive letter is not absolute on Windows, so the
AC-13 host-event test saw None there. Use the platform's own root.

Status: REVIEW_PASSED_AWAITING_CI on head 770e6ebb5162ca5054bd602ca056e7e580e60e27 (previous reviewed head 770e6ebb5162ca5054bd602ca056e7e580e60e27, CCR-20261110-008). The review of this head is complete, and no open finding blocks approval. This is not an approval. Two required CI checks of this head have failed (see CI), and the cycle's CI gate decides on them.

What changed since the previous review

Nothing. The head is the same commit that CCR-20261110-008 reviewed. This run belongs to a new cycle plan (plan-cycle-019fd7d3…, revision 4), so the review was repeated in full on the current head, and every local check was run again.

The diff under review was the accumulated diff origin/main...770e6eb (merge base c1f6265, 19 files, +3725/−133). Its line count (4698) was confirmed. Its SHA-256 was not recomputed, because sha256sum is outside this stage's table. Every source and documentation hunk was read: scripts/grants.py, scripts/stage_permissions.py, scripts/command_permissions.py, scripts/cycle.py, scripts/executors.py, scripts/user_choices.py, the JSON manifests, docs/host-permissions.md, docs/configuration.md, docs/capability-parity-audit.md and docs/ROADMAP_V2.md. The test files and fixtures were covered by running them, not by reading every line.

Security

  • Triage: the deterministic minimum did not fire, because no CI, secret or agent-configuration path changed. The change alters the toolkit's own permission and consent boundary, and the plan sets security_required. cc-security-review therefore ran as a delegated pass on the accumulated diff at this head: security_audit_ran=true.
  • Confirmed vulnerabilities: none.
  • Reviewed:
    • Session tool-results allowance: the directory comes only from the host event (session_id plus <session_id>.jsonl). Its shape is checked, membership resolves symlinks and .., and a symlinked root covers nothing.
    • The COMMAND_PERMISSION_TOOL_RESULTS marker: its shape is checked in _observed_policy, and it serves only runtime reconstruction. The hook decides at execution time.
    • Regex grants: structural validation rejects nested repetition, alternation under repetition, backreferences and lookarounds. Matching runs in an isolated python3 -I subprocess, with JSON on stdin, a 500 ms budget and no shell. A timeout grants nothing.
    • Pattern matching lifts only table membership: protected_reason runs first, in both check and matching_answer.
    • The persistent/forever → cycle narrowing for dispatch-unique paths, and the refusal of forever for review roles. The store check now runs after the role check, and both still run.
    • The credential guard across compound segments, directory changes, tilde prefixes and globs, plus redirect targets resolved against cwd.
    • The Bash(*) host allow for pattern, check or shell grants: it is documented, and the hook (onFailure: block) stays the concrete gate.
    • Execution evidence (command_executions, record_execution): audit data only. It requires an existing allow grant and never creates authorization.
  • Potential risks (low, already disclosed):
    • A repository grant for an interpreter run on <TOOL_RESULTS>/<OUTPUT> executes whatever saved output matches, and that content may be untrusted. The question warns about this.
    • The static Bash model is not a full grammar.
  • Not reviewed: Claude Code's own permission layer and future transcript_path layouts. A different layout falls back to the ordinary question.

configured-test, attempt 1: this run went past the 600 s foreground limit, so the host moved it to the background. It finished with Ran 2577 tests in 849.370s — FAILED (failures=1, skipped=1), exit 1. The failure was test_stats.StatsTests.test_work_item_outcomes_fold_legacy_cycle_into_its_only_known_scope ((1, 1, 0) != (0, 0, 0)). While it ran, the other checks were also running in parallel. The same test passes on its own, and tests.test_stats passes as a module (43 tests). Neither tests/test_stats.py nor scripts/stats.py is in this diff. Attempt 2 ran the full suite alone in the foreground and passed. I judge it a load-dependent flake outside this change. It is not a finding.

The codex-owned checks ran under this Claude rereview dispatch, and their identities are kept unchanged.

Conclusion: not_verified. AC-8's native baselines did not run. AC-15–AC-26 have no linked frozen check, so they remain open.

Denied accessory operations (none essential, no check affected):

  • grep -o … <session tool-results>/bnzu12x6t.txt (command_table: reading outside the stage workspace). The installed runtime hook predates this PR's AC-13 allowance. The PR comments were read with gh pr view --json comments --jq instead.
  • timeout 240 tail -n 0 -f <task output> (command_table), and a Monitor loop containing ; (command_table). The wait for attempt 1 was done by polling with tail -c.
  • Read $TMPDIR/c25.md and the ctx_execute_file MCP tool (Claude permission layer). The same data was read directly with gh.

Residual risk and verdict

  • The static Bash model is still not a full grammar (see the REV-001–REV-016 history).
  • The tool-results allowance relies on Claude Code's hook event and directory layout.
  • AC-8 native parity and AC-15–AC-26 have no executed evidence.
  • test_stats showed one flake under parallel load, outside this change.
  • Two required CI checks fail at this head.
  • Project verdict: no blocking finding is open, and REV-019 is low and non-blocking. The review of this head is complete. Approval waits for the CI gate, which currently sees two failed checks.

Status: REVIEW_PASSED_AWAITING_CI on head 96edec24c89c348fa9b17cc010cdd0e4357a07e2 (previous reviewed head 770e6ebb5162ca5054bd602ca056e7e580e60e27, CCR-20261110-009). The review of this head is complete, and no open finding blocks approval. This is not an approval: the required CI checks of this head are still running, and the cycle's CI gate decides on them.

What changed since the previous review

One commit, 96edec2 — test(consent): build the session tool-results path from the platform root (#439). It changes only tests/test_consent_variants.py (+5/−2). test_ac13_session_tool_results_directory_comes_only_from_the_host_event used a rooted POSIX path (/srv/agent/...) as the transcript path. That path is not absolute on Windows, so session_tool_results correctly returned None there, and the test failed. The test now builds the path from os.path.abspath(os.sep). This targets the windows-3 shard failure reported in the previous rereview. The change touches no product code, and the negative cases (projects/abc-1.jsonl, ../abc-1, a missing transcript, None) are unchanged. os is already imported.

The diff under review was the runtime's accumulated diff origin/main...96edec2 (merge base c1f6265, 19 files, +3728/−133). Its line count (4701) was confirmed. Its SHA-256 was not recomputed, because sha256sum is outside this stage's table. The source hunks of scripts/grants.py, scripts/command_permissions.py, scripts/cycle.py, scripts/executors.py and the documentation hunks were read again, along with the delta and the relevant parts of scripts/stage_permissions.py (session_tool_results, inside_tool_results). The rest of the accumulated diff is byte-for-byte what CCR-20261110-009 reviewed: the only difference between the two heads is the 7-line test delta above.

Findings

[REV-001] · high · resolved · valid · blocks:yes — Regex grants match raw compound shell source, so a simple-command pattern authorizes other segments

Still resolved. pattern_covers_operation requires compound: true for <SHELL> operations. issue-439-regression passes at this head (64 tests).

[REV-002] · medium · resolved · valid · blocks:yes — The segment credential guard compares literal paths, so cd options, pushd and globs get past it

Still resolved. issue-439-regression passes.

[REV-003] · medium · resolved · valid · blocks:no — Every consent question names the configured test command, even for unrelated commands

Still resolved. refused_operation names a configured command only when its program word matches. issue-439-regression passes.

[REV-004] · medium · resolved · valid · blocks:no — An invalid edited pattern, or forever for review, ends the whole cycle instead of asking again

Still resolved. The interactive loop in ConsentBroker asks again with validation_error. issue-439-regression passes.

[REV-005] · low · resolved · valid · blocks:no — The "Codex" AC-8 parity test does not exercise Codex

Still resolved at the test level. The native Codex baseline itself remains unverified (see Verification).

[REV-006] · medium · resolved · valid · blocks:yes — A relative argument after cd "$VAR" is refused with no consent question, even when it is not a path

Still resolved. issue-439-regression passes.

[REV-007] · low · resolved · valid · blocks:no — Glob credential matching lets * cross /, so unrelated absolute globs count as credential reads

Still resolved. issue-439-regression passes.

[REV-008] · medium · resolved · valid · blocks:yes — builtin cd, command cd and CDPATH still get past the segment credential guard

Still resolved. issue-439-regression passes.

[REV-009] · medium · resolved · valid · blocks:yes — Tilde prefixes ~user, ~+ and ~- are expanded as ~, so the credential guard checks the wrong path

Still resolved. issue-439-regression passes.

[REV-010] · low · resolved · valid · blocks:no — The env -C guard applies only when env is the program word, so command env -C "$X" and wrapped forms get past it

Still resolved. issue-439-regression passes.

[REV-011] · medium · resolved · valid · blocks:yes — CDPATH, HOME, OLDPWD, dotglob and GLOBIGNORE are detected in the raw source, so continuations and quoting the parser decodes hide them

Still resolved. issue-439-regression passes.

[REV-012] · medium · resolved · valid · blocks:yes — Glob options other than dotglob are not modelled, so nocaseglob lets a differently cased glob reach a store

Still resolved. issue-439-regression passes.

[REV-013] · medium · resolved · valid · blocks:yes — The extglob tokenizer counts parentheses inside ${…} and $[…], so it folds the commands after an extglob into one operand

Still resolved. issue-439-regression passes.

[REV-014] · medium · resolved · valid · blocks:yes — A case pattern's ) inside $(…) ends the substitution early, so later commands are hidden from the segment guards

Still resolved. The REV014_LOOP_FORMS cases in issue-439-regression pass at this head.

[REV-015] · medium · resolved · valid · blocks:yes — A { body after for NAME, select NAME or function NAME, and coproc, keep the body's first command inside the keyword's segment

Still resolved. issue-439-regression passes.

[REV-016] · medium · resolved · valid · blocks:yes — A quoted reserved word after coproc NAME is read as a compound keyword, so the coprocess program is dropped and its guards are skipped

Still resolved. issue-439-regression passes.

[REV-017] · medium · resolved · valid · blocks:yes — Reads under the stage session's own Claude tool-results directory are still outside the workspace, so every new dispatch asks again (AC-13)

Still resolved. issue-439-session-outputs passes at this head (6 tests), including the updated platform-rooted AC-13 test. session_tool_results still requires an absolute transcript path named <session_id>.jsonl, and inside_tool_results checks membership by real path and refuses a symlinked root.

[REV-018] · medium · resolved · valid · blocks:yes — A grant for a path unique to one dispatch or session is still offered as persistent/forever, and the question does not say it can never match again (AC-14)

Still resolved. issue-439-session-outputs passes. command_options(unique_path=…) offers this cycle / deny, and apply_answer narrows persistent/forever to cycle.

[REV-019] · low · open · - · blocks:no — The new detail[:120] cut truncates a configured command longer than 98 characters in the consent question (AC-2)

Still reproducible. The new commit does not touch it. scripts/grants.py:374 still builds …{scope_note}{detail[:120]}…, and scripts/grants.py:355 sets detail = " Configured command: " + configured + ".". A configured command longer than 98 characters is therefore only partly named, while AC-2 asks for the exact command. It is low and non-blocking, because the full command is still in the permission record that goes with the question. Suggested fix: keep detail whole and shorten another part of the prompt, then add a test with a configured command longer than 98 characters.

No new findings.

Security

  • Triage: the deterministic minimum did not fire, because no CI, secret or agent-configuration path changed. The change alters the toolkit's own permission and consent boundary, and the plan sets security_required. cc-security-review therefore ran as a delegated pass on the accumulated diff at this head: security_audit_ran=true.
  • Confirmed vulnerabilities: none.
  • Delta: test-only. It crosses no trust boundary and does not relax session_tool_results. The production check still rejects a non-absolute transcript path, and the test now uses a path that is absolute on every platform.
  • Reviewed again:
    • The session tool-results allowance: the directory comes only from the host event, membership resolves symlinks and .., and a symlinked root covers nothing.
    • The COMMAND_PERMISSION_TOOL_RESULTS marker: its shape is checked in _observed_policy, and it is used only for runtime reconstruction.
    • Regex grants: structural validation plus an isolated python3 -I subprocess with a 500 ms budget and no shell. A timeout grants nothing.
    • Pattern matching lifts only table membership, because protected_reason runs first.
    • The persistent/forever → cycle narrowing.
    • Execution evidence (record_execution): audit data only, and it requires an existing allow grant.
  • Potential risks (low, already disclosed):
    • A repository grant for an interpreter run on <TOOL_RESULTS>/<OUTPUT> executes whatever saved output matches, and that output may be untrusted. The question warns about this.
    • The static Bash model is not a full grammar.
  • Not reviewed: Claude Code's own permission layer and future transcript_path layouts.

Status: REVIEW_PASSED_AWAITING_CI on head 96edec24c89c348fa9b17cc010cdd0e4357a07e2 (previous reviewed head 96edec24c89c348fa9b17cc010cdd0e4357a07e2, CCR-20261110-010). The review of this head is complete, and no open finding blocks approval. This is not an approval: one required CI check of this head is still running, and the cycle's CI gate decides.

What changed since the previous review

Nothing in the code. This run verifies the recovered attempt attempt-e069761d5e684d46900c2c616e80f306 (CCR-20261110-010) at the same head, under plan revision 6. Every claimed finding ID, REV-001 to REV-018, was checked again by running its checks at this head. Every local check was run again.

The diff under review was the runtime's accumulated diff origin/main...96edec2 (merge base c1f6265, 19 files, +3728/−133). Its line count (4701) was confirmed. Its SHA-256 was not recomputed, because sha256sum is outside this stage's table. The source hunks of scripts/command_permissions.py, scripts/cycle.py, scripts/executors.py and scripts/grants.py were read again, along with the session tool-results helpers in scripts/stage_permissions.py (session_tool_results, is_session_tool_results, inside_tool_results, dispatch_unique_path). The local checkout matches the head.

Findings

[REV-001] · high · resolved · valid · blocks:yes — Regex grants match raw compound shell source, so a simple-command pattern authorizes other segments

Verified again. pattern_covers_operation (scripts/grants.py) still requires compound: true for <SHELL> operations. issue-439-regression passes at this head (64 tests).

[REV-002] · medium · resolved · valid · blocks:yes — The segment credential guard compares literal paths, so cd options, pushd and globs get past it

Verified again: issue-439-regression passes.

[REV-003] · medium · resolved · valid · blocks:no — Every consent question names the configured test command, even for unrelated commands

Verified again. refused_operation sets configured_command only when the program word matches. issue-439-regression passes.

[REV-004] · medium · resolved · valid · blocks:no — An invalid edited pattern, or forever for review, ends the whole cycle instead of asking again

Verified again. The ConsentBroker loop asks again with validation_error. issue-439-regression passes.

[REV-005] · low · resolved · valid · blocks:no — The "Codex" AC-8 parity test does not exercise Codex

Verified again at the test level: issue-439-regression passes. The native Codex baseline itself is still unverified (see Verification).

[REV-006] · medium · resolved · valid · blocks:yes — A relative argument after cd "$VAR" is refused with no consent question, even when it is not a path

Verified again. refused_operation marks unresolved_directory, and the question warns about it. issue-439-regression passes.

[REV-007] · low · resolved · valid · blocks:no — Glob credential matching lets * cross /, so unrelated absolute globs count as credential reads

Verified again: issue-439-regression passes.

[REV-008] · medium · resolved · valid · blocks:yes — builtin cd, command cd and CDPATH still get past the segment credential guard

Verified again: issue-439-regression passes.

[REV-009] · medium · resolved · valid · blocks:yes — Tilde prefixes ~user, ~+ and ~- are expanded as ~, so the credential guard checks the wrong path

Verified again: issue-439-regression passes.

[REV-010] · low · resolved · valid · blocks:no — The env -C guard applies only when env is the program word, so command env -C "$X" and wrapped forms get past it

Verified again: issue-439-regression passes.

[REV-011] · medium · resolved · valid · blocks:yes — CDPATH, HOME, OLDPWD, dotglob and GLOBIGNORE are detected in the raw source, so continuations and quoting the parser decodes hide them

Verified again: issue-439-regression passes.

[REV-012] · medium · resolved · valid · blocks:yes — Glob options other than dotglob are not modelled, so nocaseglob lets a differently cased glob reach a store

Verified again: issue-439-regression passes.

[REV-013] · medium · resolved · valid · blocks:yes — The extglob tokenizer counts parentheses inside ${…} and $[…], so it folds the commands after an extglob into one operand

Verified again: issue-439-regression passes.

[REV-014] · medium · resolved · valid · blocks:yes — A case pattern's ) inside $(…) ends the substitution early, so later commands are hidden from the segment guards

Verified again: the REV014_LOOP_FORMS cases in issue-439-regression pass.

[REV-015] · medium · resolved · valid · blocks:yes — A { body after for NAME, select NAME or function NAME, and coproc, keep the body's first command inside the keyword's segment

Verified again: issue-439-regression passes.

[REV-016] · medium · resolved · valid · blocks:yes — A quoted reserved word after coproc NAME is read as a compound keyword, so the coprocess program is dropped and its guards are skipped

Verified again: issue-439-regression passes.

[REV-017] · medium · resolved · valid · blocks:yes — Reads under the stage session's own Claude tool-results directory are still outside the workspace, so every new dispatch asks again (AC-13)

Verified again. issue-439-session-outputs passes at this head: 6 tests, including test_ac13_session_tool_results_directory_comes_only_from_the_host_event and test_ac13_own_session_reads_ask_nothing_and_another_session_still_asks. session_tool_results still requires an absolute transcript path named <session_id>.jsonl. inside_tool_results refuses a symlinked root and checks membership by real path.

[REV-018] · medium · resolved · valid · blocks:yes — A grant for a path unique to one dispatch or session is still offered as persistent/forever, and the question does not say it can never match again (AC-14)

Verified again. test_ac14_dispatch_unique_operands_are_offered_this_cycle_only passes. command_options(unique_path=…) returns this cycle / deny, and apply_answer narrows persistent/forever to cycle.

[REV-019] · low · open · - · blocks:no — The new detail[:120] cut truncates a configured command longer than 98 characters in the consent question (AC-2)

Still reproducible at this head. scripts/grants.py:374 still builds …{scope_note}{detail[:120]}…, and scripts/grants.py:355 sets detail = " Configured command: " + configured + ".". A configured command longer than 98 characters is therefore only partly named, while AC-2 asks for the exact command. It is low and non-blocking, because the full command is still in the permission record that goes with the question. Suggested fix: keep detail whole, shorten another part of the prompt, and add a test with a configured command longer than 98 characters.

No new findings.

Security

  • Triage: the deterministic minimum did not fire, because no CI, secret or agent-configuration path changed. The change alters the toolkit's own permission and consent boundary, and the plan sets security_required. cc-security-review therefore ran as a delegated pass on the accumulated diff at this head: security_audit_ran=true.
  • Confirmed vulnerabilities: none.
  • Reviewed:
    • The session tool-results allowance. The directory comes only from the host event (session_id plus <session_id>.jsonl). Its shape is checked. Membership resolves symlinks and .., and a symlinked root covers nothing.
    • The COMMAND_PERMISSION_TOOL_RESULTS marker. _observed_policy checks its shape, and the marker serves only runtime reconstruction. The hook decides at execution time.
    • Regex grants. Structural validation rejects nested repetition, alternation under repetition, backreferences and lookarounds. Matching runs in an isolated python3 -I subprocess, with JSON on stdin, a 500 ms budget and no shell. A timeout grants nothing.
    • Pattern matching lifts only table membership, because protected_reason runs first.
    • The persistent/forever → cycle narrowing for dispatch-unique paths. The role check for forever now runs before the store check, and both still run.
    • Execution evidence (command_executions, record_execution) is audit data only. It requires an existing allow grant and never creates authorization.
  • Potential risks (low, already disclosed):
    • A repository grant for an interpreter run on <TOOL_RESULTS>/<OUTPUT> executes whatever saved output matches, and that output may be untrusted. The question warns about this.
    • The static Bash model is not a full grammar.
  • Not reviewed: Claude Code's own permission layer, and future transcript_path layouts.

Verification — agent-reported, tests.version=2

Every check ran in the foreground in this disposable clone at 96edec24c89c348fa9b17cc010cdd0e4357a07e2, one at a time.

Check ID Executor/profile Criteria Result Evidence
configured-test codex/deep_coder — pass (exit 0) Ran 2577 tests in 495.051s — OK (skipped=1)
issue-439-regression codex/deep_coder AC-1–AC-12 pass (exit 0) Ran 64 tests in 69.035s — OK
issue-439-session-outputs claude/deep_coder AC-13, AC-14 pass (exit 0) Ran 6 tests in 2.073s — OK
package-validation codex/deep_coder — pass (exit 0) VALID: 16 skills (7 cycle, 9 supporting), shared sections in sync, cross-agent manifests aligned
type-check codex/deep_coder — pass (exit 0) 0 errors, 0 warnings, 0 notes
consent-characterization codex/deep_coder AC-9 pass (exit 0) Ran 6 tests in 6.350s — OK
native-claude-parity claude/deep_coder AC-8 unverified The frozen command is an opaque digest (sha256:fbede285…) with no runnable binding in this stage.
native-codex-parity codex/deep_coder AC-8 unverified Opaque digest (sha256:162dc22c…). The nested Codex socket mask also prevents codex exec from a stage (docs/routing.md).

The codex-owned checks ran under this Claude rereview dispatch, and their identities are unchanged.

Conclusion: not_verified. AC-8's native baselines did not run. AC-15–AC-26 have no linked frozen check, so they remain open.

Denied accessory operations (none essential, no check affected): grep over the session's saved gh pr view --comments output (command_table: reading outside the stage workspace), and the ctx_execute_file MCP tool (Claude permission layer). The same PR history was saved to $TMPDIR and read from there.

CI (head 96edec2, read once; parallel policy)

Check State
Skills, manifests, and Bash installer pass (13m5s)
Windows test shard (windows-1) pass (12m54s)
Windows test shard (windows-2) pass (5m36s)
Windows test shard (windows-3) pending
Windows test shard (windows-4) pass (16m8s)
PowerShell installer not reported in this head's rollup

4 passed, 0 failed, 1 pending. windows-3 runs test_consent_variants, the shard that failed on 770e6eb and that 96edec2 targets. The cycle's CI gate decides on it and on the absent PowerShell installer check. These states are reported here, not as findings.

Residual risk and verdict

  • The static Bash model is still not a full grammar (see the REV-001–REV-016 history).
  • The tool-results allowance depends on Claude Code's hook event and directory layout.
  • AC-8 native parity and AC-15–AC-26 have no executed evidence.
  • Whether 96edec2 fixes the windows-3 failure is known only when that shard finishes. The local Linux run passes.
  • Project verdict: no blocking finding is open, and REV-019 is low and non-blocking. The review of this head is complete. Approval waits for the CI gate.

Status: APPROVED on head 96edec24c89c348fa9b17cc010cdd0e4357a07e2 (previous reviewed head 96edec24c89c348fa9b17cc010cdd0e4357a07e2, CCR-20261110-011). The head was rereviewed in full, every previous finding was classified, no open finding blocks approval, and all 6 CI checks of this head have passed. Local verification is still not_verified, because the AC-8 native parity baselines did not run (see Verification). The cycle's gates decide on that.

What changed since the previous review

Nothing in the code. This run is a new attempt (attempt-0ba65e358b584b0d879a71d17442e491) at the same head, under plan plan-cycle-758f50132f9d472eb280ecc73b81a516 revision 4. Since CCR-20261110-011, the pending Windows test shard (windows-3) and the absent PowerShell installer have both reported and passed.

The diff under review is the runtime's accumulated diff origin/main...96edec2 (merge base c1f6265, 19 files, +3728/−133). Its line count (4701) was confirmed. Its SHA-256 was not recomputed, because sha256sum is outside this stage's table. The local checkout is at the head. These parts were read again:

  • the source hunks of scripts/command_permissions.py, scripts/cycle.py, scripts/executors.py and scripts/grants.py;
  • the session tool-results helpers in scripts/stage_permissions.py (session_tool_results, is_session_tool_results, inside_tool_results, dispatch_unique_path);
  • the read-operand check (scripts/stage_permissions.py:1478-1487) and the hook entry point _hook_main (scripts/stage_permissions.py:3134-3191).

Findings

[REV-001] · high · resolved · valid · blocks:yes — Regex grants match raw compound shell source, so a simple-command pattern authorizes other segments

Verified again. pattern_covers_operation still requires compound: true for a <SHELL> operation. issue-439-regression passes at this head (64 tests).

[REV-002] · medium · resolved · valid · blocks:yes — The segment credential guard compares literal paths, so cd options, pushd and globs get past it

Verified again: issue-439-regression passes.

[REV-003] · medium · resolved · valid · blocks:no — Every consent question names the configured test command, even for unrelated commands

Verified again. refused_operation sets configured_command only when the program word matches a configured command. issue-439-regression passes.

[REV-004] · medium · resolved · valid · blocks:no — An invalid edited pattern, or forever for review, ends the whole cycle instead of asking again

Verified again. The ConsentBroker loop asks again with validation_error, and the role check for forever runs before the store check. issue-439-regression passes.

[REV-005] · low · resolved · valid · blocks:no — The "Codex" AC-8 parity test does not exercise Codex

Verified again at the test level: issue-439-regression passes. The native Codex baseline itself is still unverified (see Verification).

[REV-006] · medium · resolved · valid · blocks:yes — A relative argument after cd "$VAR" is refused with no consent question, even when it is not a path

Verified again. refused_operation marks unresolved_directory, and the question warns about it. issue-439-regression passes.

[REV-007] · low · resolved · valid · blocks:no — Glob credential matching lets * cross /, so unrelated absolute globs count as credential reads

Verified again: issue-439-regression passes.

[REV-008] · medium · resolved · valid · blocks:yes — builtin cd, command cd and CDPATH still get past the segment credential guard

Verified again: issue-439-regression passes.

[REV-009] · medium · resolved · valid · blocks:yes — Tilde prefixes ~user, ~+ and ~- are expanded as ~, so the credential guard checks the wrong path

Verified again: issue-439-regression passes.

[REV-010] · low · resolved · valid · blocks:no — The env -C guard applies only when env is the program word, so command env -C "$X" and wrapped forms get past it

Verified again: issue-439-regression passes.

[REV-011] · medium · resolved · valid · blocks:yes — CDPATH, HOME, OLDPWD, dotglob and GLOBIGNORE are detected in the raw source, so continuations and quoting the parser decodes hide them

Verified again: issue-439-regression passes.

[REV-012] · medium · resolved · valid · blocks:yes — Glob options other than dotglob are not modelled, so nocaseglob lets a differently cased glob reach a store

Verified again: issue-439-regression passes.

[REV-013] · medium · resolved · valid · blocks:yes — The extglob tokenizer counts parentheses inside ${…} and $[…], so it folds the commands after an extglob into one operand

Verified again: issue-439-regression passes.

[REV-014] · medium · resolved · valid · blocks:yes — A case pattern's ) inside $(…) ends the substitution early, so later commands are hidden from the segment guards

Verified again: the REV014_LOOP_FORMS cases in issue-439-regression pass.

[REV-015] · medium · resolved · valid · blocks:yes — A { body after for NAME, select NAME or function NAME, and coproc, keep the body's first command inside the keyword's segment

Verified again: issue-439-regression passes.

[REV-016] · medium · resolved · valid · blocks:yes — A quoted reserved word after coproc NAME is read as a compound keyword, so the coprocess program is dropped and its guards are skipped

Verified again: issue-439-regression passes.

[REV-017] · medium · resolved · valid · blocks:yes — Reads under the stage session's own Claude tool-results directory are still outside the workspace, so every new dispatch asks again (AC-13)

Verified again. issue-439-session-outputs passes at this head (6 tests). _hook_main derives tool_results only from the host event (session_tool_results(event)), and the read-operand check accepts a path inside it (scripts/stage_permissions.py:1486).

This dispatch's own grep of its saved gh pr view output was refused with reading outside the stage workspace needs operation consent (the cycle journal is unavailable (ImportError)). That refusal carried no COMMAND_PERMISSION_TOOL_RESULTS marker. So the refusal came from the runtime installed at ~/.code-cycle/runtime, which does not include this change yet, and not from the code at this head. It is not evidence against the fix.

[REV-018] · medium · resolved · valid · blocks:yes — A grant for a path unique to one dispatch or session is still offered as persistent/forever, and the question does not say it can never match again (AC-14)

Verified again. test_ac14_dispatch_unique_operands_are_offered_this_cycle_only passes. command_options(unique_path=…) returns this cycle / deny, and apply_answer narrows persistent/forever to cycle.

[REV-019] · low · open · - · blocks:no — The new detail[:120] cut truncates a configured command longer than 98 characters in the consent question (AC-2)

Still reproducible at this head. scripts/grants.py:355 builds detail = " Configured command: " + configured + ".", and scripts/grants.py:374 still inserts {detail[:120]} into the prompt. A configured command longer than 98 characters is therefore only partly named, while AC-2 asks for the exact command. It does not block, because the full command is still in the permission record that goes with the question. Suggested fix: keep detail whole, shorten another part of the prompt, and add a test with a configured command longer than 98 characters.

No new findings.

Security

  • Triage: the deterministic minimum did not fire, because no CI, secret or agent-configuration path changed. The change alters the toolkit's own permission and consent boundary, and the plan sets security_required. cc-security-review therefore ran as a delegated pass on the accumulated diff at this head: security_audit_ran=true.
  • Confirmed vulnerabilities: none.
  • Reviewed surface:
    • The session tool-results allowance. The directory comes only from the host event: session_id must match SESSION_ID, and transcript_path must be absolute and named <session_id>.jsonl. Its shape is checked as …/projects/<dir>/<session>/tool-results. Membership resolves symlinks and .., a symlinked root covers nothing, and protected_reason still runs first.
    • The COMMAND_PERMISSION_TOOL_RESULTS marker. _observed_policy accepts it only in the session shape, and it serves only runtime reconstruction. The hook decides at execution time from the event.
    • Regex grants. Structural validation rejects nested repetition, alternation under repetition, backreferences and lookarounds, the empty match, and missing positive or negative examples. Matching runs in an isolated python3 -I -c subprocess, with JSON on stdin, no shell, size limits and a 500 ms budget. A timeout grants nothing.
    • Agent-proposed patterns (command_pattern_proposals). They are re-validated, must cover the refused operation, and fall back to the exact grant. They become authorization only through a user answer.
    • The persistent/forever → cycle narrowing for dispatch-unique paths, and the review-role forever refusal.
    • Execution evidence (command_executions, record_execution). It is audit data only, needs an existing allow grant, and never creates authorization.
  • Potential risks (low, already disclosed):
    • A repository grant for an interpreter run on <TOOL_RESULTS>/<OUTPUT> executes whatever saved output matches, and that output may be untrusted. The question warns about this.
    • The static Bash model is not a full grammar.
  • Not reviewed: Claude Code's own permission layer, future transcript_path layouts, and the installed runtime at ~/.code-cycle/runtime, which is not this head.

Verification — agent-reported, tests.version=2

Every check ran in the foreground in this disposable clone at 96edec24c89c348fa9b17cc010cdd0e4357a07e2, one at a time.

native-codex-parity codex/deep_coder AC-8 unverified Opaque digest (sha256:162dc22c…). The nested Codex socket mask also prevents codex exec from a stage (docs/routing.md).

The codex-owned checks ran under this Claude rereview dispatch, and their identities are unchanged.

Conclusion: not_verified. AC-8's native baselines did not run. AC-15–AC-26 have no linked frozen check, so they stay open.

Denied accessory operations (none essential, no check affected):

  • grep -o -E … <session>/tool-results/bcdjkxm1b.txt was refused (command_table, installed runtime). The same PR history was read with gh … --jq instead.
  • The ctx_execute_file MCP tool was refused by Claude's permission layer.

Residual risk and verdict

  • The static Bash model is still not a full grammar (see the REV-001–REV-016 history).
  • The tool-results allowance depends on Claude Code's hook event and directory layout. It takes effect only once the installed runtime includes this change.
  • AC-8 native parity and AC-15–AC-26 have no executed evidence.
  • Project verdict: no blocking finding is open. REV-019 is low and does not block. Every CI check of this head passed: APPROVED, with local verification not_verified for the reasons above.
