Three spellings of the home reached that compare as no word it names, and allowed: - a backslash-newline inside the name (`rm -rf $HO\ME`): bash drops it before it reads the name, and simpleParamEnd now runs the name on across it, so the spelling is `$HOME`, not `${HO}ME`; - a variable inside a brace group (`{$HOME,x}`, `$HOME/{.*,}`, `$HO{ME,}`): bash expands the group before it reads the variable, and each word the expander makes now keeps its variables' sites (bword.s), so it is spelled as bash reads it, a bare name running on into the group's unquoted text; - a parameter expansion with an operator that can leave the value as it is (`${HOME%/}`, `${HOME:-x}`, `${HOME#}`, `${HOME/x/x}`, a substring, a case change, a subscript), and an alternative whose word is one of these (`${X:+$HOME}`): spellParameter spells each as `${NAME}`. Judgement taken: "can be the home" decides, so an expansion whose pattern might not match blocks, and a suffix trim that leaves the path above the home (`${HOME%/*}`) blocks too. Stated over-blocks, all rare: `${HOME#/}` (a relative path), `$HO''{ME,}`, and `sh -c "rm -rf $HO{ME,}"`, where the outer shell has already expanded `$HO`. Named as residuals in 17-guard.md and commands/guard.md: a default's own word (`${DIR:-$HOME}`), an alternative nested more than three deep, and `${PWD:0:1}` (the root, read as `$PWD`). Verdict diff over 12,595 pre-existing inputs (every guard test literal, both corpora and every bundled fixture, bare, in sh -c "..." and in bash -c '...'), base 8cd7f88f4 against this tree: 6 differences, all tightening, all the two residual pins this change flips (`{$HOME,x}`, `${HOME:-/}`).

The scanner's bundled secret patterns anchor their start on a leading word boundary, and '_' and every letter or digit are word characters, so a token that sits right after one has no boundary and is never matched: the implement loop's laneFileGap (internal/core/implement/loop/receipt.go) returns the receipt's path as notes_ followed by a GitHub PAT and .md, does not exist, with the token raw, and memory's ValidateDistilledPage (internal/core/memory/schema.go) returns unknown key(s) [notes_ followed by the token] raw, while notes- and sub/ spellings seal. A letter on both sides (x, token, y) is missed the same way. Every RedactRefusal caller shares the gap (scribe, release, ideate, lifeboat, reading, intent, memory, implement loop), so a host payload's key or path carries a credential to the terminal and the transcript through a refusal. It is the refusal-side twin of the page-filename gap iss-2609290411321963 closed with filenameJudgeTexts. Found by the security review of lane drainEcho3. Fix direction: in the primitive, not the callers; re-find the secret patterns with their leading boundary removed, through the scanner's own linear adjacency machinery, and seal every glued match byte for byte through Redact; fail closed as before. Detector: a refusal naming a key or a path in which a well-formed token sits behind an underscore or a letter carries the token sealed.

The primitive now adds a glued sweep: the hard_fail secret patterns that open on \b are recompiled without it and run once through the scanner's own adjacency machinery, so every start position a suffix sweep would try is tried in one linear pass. Its findings are deduplicated with ScanText's and sealed by Redact, so a bounded token keeps the fingerprint it had. The primitive still fails closed: on a degraded scanner, on a sweep it cannot build, and now on a secret span that survives Redact. ScanText itself is unchanged.

The ledger's reader (issuerecord), record-lint's schema gate and the cold-reading definition locator each kept a private copy of that strip, and a caller that forgot it refused well-formed records with a message comparing a value against itself. frontmatter.UnquoteScalar is the strip beside the decoder: a value that opens and closes with a double quote comes back decoded with quoted=true, anything else unchanged with quoted=false, so the ledger reader that reads a bare value as a number branches on the flag instead of re-testing the quotes. The three call sites and the ledger reader's quotedScalar predicate move onto it; it trims nothing, as none of them relied on it trimming. The changelog gate's scalar is left alone: it strips either quote kind on purpose and says why.

The loader is the host's, so the fix is where the files live, as it was for commands/README.md (iss-160). Both move, unchanged in substance, to .abcd/development/agents/: the operator statement of the prompt contract and the itd-5 prompt-version log, durable record rather than plugin payload. record-lint's agent_contract reads the log from its configured `changelog` path, which follows it; the prompt-quality chapter, the surfaces chapter, itd-5's rule text, the Makefile note and the code comments that named the old paths follow too, and the development index gains the folder. Dated plans, research notes and closed records keep the paths they were written against. TestPluginAgentSurfaceRegistersOnlyAgents is the detector, the agent half of the iss-160 command-surface test: every markdown file at the top of agents/ must open a frontmatter block naming itself after its file. Watched RED on the two files before the move and GREEN after.

A document opened at every depth of a deep nest made that quadratic in bytes allocated (14.2x when the nest quadruples). The pending list is now one list with a floor: a substitution reads the documents from the floor it sets, the ones below wait for the line after it closes, and a closed-over document stays where it stands. TestClosedOverDocumentsStayLinear holds the allocation growth to the work bar (4.27x), and three new shapes join TestHomeSpellingsStayLinear (3.94-4.00x).

A ~/.abcd every account can write, or one another account owns, holding a 0600 file of the caller's read as DeclarationOK, though whoever can change the directory can rename or hard-link a file of the caller's shape in under a declaration's name. Each directory level below home is now judged on the descriptor opened for it, after that descriptor is confirmed to be the level vetted: other-write (sticky or not; a sticky directory still admits a hard link under an absent name) or an owner that is neither this uid nor root is DeclarationDirectoryExposed, with a *HomeScopeExposedError naming the directory and the repair. Absence is still decided first, and home itself is still not judged. Every caller renders the new refusal with the directory's sentence, beside its symlinked-directory case. Group-write is deliberately not refused: a ~/.abcd made by hand with the documented mkdir under a user-private-group umask of 002 is 0775, and refusing it would newly refuse those installs. That stays an open question on the record.

Today it refuses a folder every account can write, and one another account owns, but reads from a group-writable one (0775). Refusing would protect a machine where the group really is shared with other people. It would also newly refuse ordinary installs on Debian and Ubuntu, where the login umask for a user whose group is private to them is 002, so the documented 'mkdir -p ~/.abcd' makes a 0775 folder whose group is only its owner. abcd's own writers create ~/.abcd at 0755 or 0700, so only a folder made by hand is affected. Two readings already disagree: the declaration file itself is refused when group-writable, and the worktree store (implement/loop ensureStore) refuses a group-writable ~/.abcd level. Deferred out of iss-2609290656480443's fix until ruled.

The kill-by-search reading gains three feeds in the same lane (iss-2609270036253187): an unquoted here-document's substitutions are the standard input of the command that opened it, a substitution runs with the pipe into its own command as its input, and a shell string is handed the output of the substitutions in its command's words as its positional parameters or text, so every command of such a string is read as handed it (`sh -c 'kill 4242' _ "$(pgrep make)"` blocks), the over-block the 2026-09-27 entry accepts for a string xargs runs. - 2026-09-28 — v0.11.1 is published: autonomous run A approved the `release` environment at 22:44:40Z under ruling A2 and the releases ruling of 2026-09-25T08:04:52Z, after the merge queue, the verify job, the tag job and main's own CI on the tagged commit 2bc519f7 reported green (every check run succeeded apart from those skipped by design; the macOS leg of the push CI was the last to report).

Root cause: the committed workflow is a GENERATED artefact. internal/core/launch/scaffold/templates/release.yml.tmpl:270 and .github/workflows/release.yml:248 both pin actions/attest@f7c74d28b9d84cb8768d0b8ca14a4bac6ef463e6 (v4.2.0), and TestSelfScaffoldParity asserts the two are byte-identical so that abcd's own release dogfoods the machinery a managed repo receives. Dependabot edits only the derived file, so parity breaks by construction on every such bump — this is recurring and structural, not a one-off. The obvious fix (bring the scaffold template into dependabot's scope) is NOT AVAILABLE: the github-actions ecosystem discovers only .github/workflows/*.yml and composite action.yml manifests under the configured directory, and no package-ecosystem scans an arbitrary .tmpl under internal/. .github/dependabot.yml today declares gomod and github-actions, both at directory /. Note also the wrong-direction trap: auto-rendering the scaffold on a dependabot PR would REVERT the bump, since render flows template -> workflow. Options, none adopted: (a) make the parity failure self-explaining — the message says 'not byte-identical' and prints the first diff but never names the template path or says 'an action bump must be applied to the template too', which is the cheapest change and matches the loud-staging principle; (b) propagate the bump backwards — a job on dependabot PRs that applies the changed pin to the template and commits to the bot branch, which is the durable fix but is custom automation writing to a bot branch; (c) drop these two workflows from dependabot's scope and manage their pins by hand from the template, trading automation for consistency. Secondary risk worth weighing: a permanently-red dependabot PR trains the maintainer to discount red CI on exactly the PRs where CI most needs to be trusted. @@ -18,3 +18,7 @@ Every dependabot PR that bumps a pinned action in .github/workflows/release.yml A `workflow_run` implementation was built and REJECTED in review on 2026-08-11, for two reasons worth recording so the next attempt does not rediscover them. First, it cannot work at all: a push made with `GITHUB_TOKEN` raises no events, so the sync commit moves the PR head to a SHA that never gets a CI run — the PR goes from red to permanently pending, a weaker signal than the failure it set out to fix. This repo already documents the mechanism at `.github/workflows/auto-release.yml` ("A GITHUB_TOKEN-pushed tag raises no tag-push event, which is why the release below invokes release.yml explicitly rather than relying on the tag"). Second, the design was unsound: `actions/checkout` with `ref: ` makes the BRANCH's tree the workspace, so a subsequent `go run ./cmd/scaffold-sync` executes branch-supplied code under the `contents: write` token that `persist-credentials: true` leaves in `.git/config`. `workflow_run` buys a trusted workflow DEFINITION, not a trusted WORKSPACE — the standard pitfall. Independent review also found the trigger fails `zizmor --persona regular` with `dangerous-triggers` (unverified locally; no docker daemon), and that committing as `github-actions[bot]` collides with the no-branch-commit tripwire in `release.yml`, which fails a release run when a bot commit lands on the default branch mid-job. Any future attempt therefore needs, at minimum: a push credential that is NOT `GITHUB_TOKEN` (a GitHub App token preferred over a PAT — short-lived and scoped, and its pushes do raise events); a structure where the untrusted tree is never executed under the write token (compute the patch in a read-only job with `persist-credentials: false`, apply and push from a trusted one checked out at `github.sha`); a commit identity that is not `github-actions[bot]`; and a concurrency group keyed on `workflow_run.event` as well as the branch, since `ci` produces both a push-derived and a pull_request-derived run per dependabot branch and the useless one can otherwise cancel the working one. + +## Deferral 2026-09-29 + +Deferred past v0.11.1: The product thinker's ruling M3 of 2026-09-23: automate it, planned next cycle as its own intent with a security review.

Today the bughunt is a Desktop prompt the user wires into an external cloud routine by hand; the direction is abcd owning the launch: the user opts in, and abcd assembles and starts the routine, applying the run contract it already governs (the human git identity per itd-131, the gates, the merge decision, the state issue). This is the realisation of the run seam — adr-27 (run is a pluggable seam, not a bespoke engine), itd-29 (the run operator surface: start/status/pause/resume/ship), itd-107 (routines assemble from one versioned template; the bughunt and a delivery-pipeline archetype), and the reframed iss-381 (the deterministic delivery pipeline survives as an itd-107 archetype, not an engine).

Owed: itd-165's planning interview, then an intent for the reorder with the post-merge content-hash check; filing both needs the product thinker's adoption." --- The fidelity audit runs after the merge, so its verdict arrives when the cheap remedies are already gone, and the code refuses any other ordering: the ingest rejects an intent that is not in the shipped bucket, and the emit fires from the ship move itself, so an intent cannot be audited against the candidate diff on a branch. The stated reason is sound as far as it goes, that a report-only review must never un-ship what has already shipped, but it answers a question that only arises because the audit was placed after the merge in the first place. Audited before the merge, a failing criterion has three cheap answers: fix the branch, revise the promise before making it, or decline to merge. Audited after, it has none, because there is no un-ship path and the code is on the trunk. The counter-argument is real and should not be waved away: a branch is not the tree that lands, since the merge queue lands merge commits and a semantic conflict with a concurrently merging change can alter the delivered reality after the verdict was formed, so the post-merge audit judges what is actually true while a pre-merge one judges a candidate. The shape that gets both is to gate on the pre-merge verdict and bind it to a content hash of the tree it judged, then check deterministically after the merge that the landed content still matches, reopening the receipt only on a mismatch, which costs one hash comparison rather than a second audit and reuses the content-addressing the transcript store already relies on. Whatever the ordering, the model's verdict must stay a proposal and a human acknowledgement must remain the gate, because a non-deterministic verdict that can block a merge on its own is a trust step this repository has not taken and would train people to route around the gate. Reframed 2026-08-29 under adr-55: the agents run autonomously and stop only to obtain a verdict, which decides this. The audit IS the stop, so it belongs before the merge, where a failed criterion still has cheap answers. A post-merge audit never stops the loop; it leaves a note. The content-hash check after the merge remains the safety net for the branch-is-not-the-landed-tree objection. + +## Deferral 2026-09-29 + +Deferred past v0.11.1: The direction is settled (adr-2609151528057260: the audit is the stop, so it belongs before the merge), and the work waits on itd-165 (draft): a pre-merge gate tuned before a corpus of real audit verdicts exists would baseline nothing.

The convention names an assisting tool, which is disclosure and deliberately not authorship, and nothing anywhere records the act that actually carries responsibility: a named person accepting a delivered promise as matching what they asked for. Adding a co-authorship trailer for the tool is the wrong repair and this repository already refuses it, since it asserts an authorship a tool cannot hold and inflates the contributor graph, and the largest project to deliberate the question chose the assisting form over the co-developed one for exactly that reason. The right shape is a separate acceptance trailer naming the human who accepted delivery, which only a person can sign, so an automated facilitator structurally cannot. It belongs on the intent rather than on a commit, because what is accepted is a delivered promise and not a diff, with a mirror on the merge commit if a commit-level trace is wanted. It should carry the verification rung alongside the name, because an acceptance is worth exactly as much as the checking behind it and an acceptance on the cheapest automatic check should not read identically to one that followed an outside audit. Refined 2026-08-29. Making it a commit trailer reintroduces the ambiguity the attribution convention already rejects, since an absent trailer and a forgotten one are the same bytes, and requiring a negative form on every commit would stamp 'nobody accepted this' on the great majority of commits, which is intermediate work no product thinker will ever accept. The resolution is that acceptance is a field on the intent rather than a trailer on a diff: the field is always present so it cannot be forgotten, and its value is null until someone accepts, which makes the absence of acceptance a statement rather than a silence. The populated form carries who accepted, when, the verification rung the acceptance rested on, and the verdict it was taken against, so an acceptance on the cheapest automatic check does not read identically to one that followed an outside audit. A commit trailer may still mirror it on the merge that ships the intent, where its presence is tied to one event rather than expected everywhere. + +## Deferral 2026-09-29 + +Deferred past v0.11.1: The product thinker's ruling M18 of 2026-09-23: planned next cycle as its own intent, not folded into itd-175, and its planning interview also answers rfc-3's first open question.

Cycle one: the pull request is armed, main moves, the strict up-to-date policy makes it BEHIND, the keep-current script updates the branch, and the full CI re-runs on the updated head before the pull request is CLEAN enough to enter the merge queue. Cycle two: the merge queue runs the full CI again on the merge group. Every merge moves main and knocks the not-yet-queued pull requests back to cycle one, so a batch of thirteen cost roughly twenty-six 13-minute cycles serialised in ALLGREEN groups, and a one-line record change waited an hour. The maintainer asks how to speed the gates up, for example by running them locally first. Directions, none adopted: (1) local-first is already built and not wired on every account: make preflight is the pre-push gate and .githooks/pre-push runs it, but core.hooksPath is unset on at least one active account, so nothing runs before a push; wire it at ahoy install (an owned ConfigChange) and record which accounts have it; note that a local pass shortens nothing on the forge, it only stops red pushes. (2) Run the full matrix once, in the queue: on the pull_request event run the fast lane only (format, record gates, ubuntu build and test) and keep the macOS leg, the race lane and the smoke harness for the merge_group event, which already runs everything; the CI classifier that stands macOS down for docs-only changes shows the seam exists. (3) Cache the Go build and test cache across runs (actions/setup-go cache keyed on go.sum) and check whether the macOS job's 13 minutes is test time or cold-build time. (4) Let the queue batch: min_entries_to_merge_wait_minutes is 0, so each pull request tends to get its own group; a short wait lets several share one CI run.

Only the first of those four exists. supersedes is schema-known through recordHandleFields and is carried by fifty-eight decision records and three others, while reverses, duplicates and refines appear in no schema and in no committed record anywhere in the tree: the field list a record may carry is related_adrs, related_intents, builds_on and blocked_by, and a record carrying a key outside the known set is dropped by the reader rather than reported, so writing one of the three missing words would make the record invisible to every surface that reads it. The consequence is that an author following the rule literally either writes a link the tooling silently discards or writes the relation in prose and calls it typed, and the corpus shows the second: records assert a typed link in a heading and carry no frontmatter edge, which reads as done to a human and is invisible to every graph walker.

Two consequences. Operationally, every pull request commit is cloned by a third party before merge, and Cloudflare exposes no delete endpoint for a build record or its logs, so whatever reaches a build log cannot be withdrawn without a vendor support request.

This is not drift in the true-then-false sense, and the distinction changes the remedy. Drift is a record that was accurate and decayed, so it is repaired by regenerating it from a source of truth. This line had no source of truth to regenerate from: it narrates an external dashboard setting that nothing in the tree can read, so its accuracy was never a property anything local could establish, and it was wrong from the moment it was written rather than becoming wrong later. `inconsistency` would carry the trajectory-neutrality better; `drift` is kept so the pair with `iss-2608220150157502` reads as one subject, and this paragraph carries what the label cannot. The remedy is correspondingly different: either a check that reads the real Cloudflare state, or an explicit demotion of the line from claim to note. Regeneration is not available.

The ingest does not branch on the verdict value: it rolls the per-criterion verdicts into counts and replaces the parked OWED marker with INGESTED whatever they say, so a verdict of all-INCONCLUSIVE closes the receipt exactly as a verdict of all-MET does. The re-emit verb then refuses to reopen it, reporting already_ingested and leaving the Audit Notes untouched, which is correct for a decided audit and wrong for an undecided one. The consequence is that there is no way to ensure the re-run that an INCONCLUSIVE calls for. The only lever that produces a fresh receipt is editing the acceptance-criteria section, because the receipt digest is taken over that section alone, which conflates two unrelated acts: clarifying a promise, and retrying an audit that was merely under-fed. This is a loud-staging violation in the precise sense the principle names, since a stage that degraded presents as a completed one. The narrow fix is for the ingest to branch: an INCONCLUSIVE leaves the receipt OWED, or moves it to a distinct re-run state, so the outstanding work stays visible without minting a ledger issue for what is an input fault rather than a product defect. Reframed 2026-08-29 under adr-55: an inconclusive verdict is a stop that needs a verdict, not a terminal state.

The drain builds its scanner from the destination repository's root, because that repository's own redaction configuration must govern its own transcripts. When the repository's directory is gone, that root cannot be resolved and the drain has nothing to run with, so the raw bytes stay staged forever with no path to redaction. This is not hypothetical: one store on this machine holds 11.7 megabytes of unredacted staged text whose repository was deleted, which is the largest single pile in the store and the only one that no amount of ordinary use will clear. The retention work just landed addresses the case where nobody opens a repository again, by draining while a session is live and by reporting other repositories' backlogs at session start, but both remedies assume the repository still exists to be opened. The options are to let a deletion of the repository be a trigger that drains or discards first, to allow a drain under an explicitly named substitute configuration with the substitution recorded on the record, or to treat the pile as terminal and offer only discard.

A glued token whose own bytes are escaped (a percent-encoded letter of its prefix, or a JSON unicode escape of its first byte, behind an underscore or a letter) therefore survives ScanText, Redact and RedactRefusal raw. Reach is narrow, since no encoder escapes an ASCII letter of a token, but the decoded layers exist to close spelling variants.

At the root a `..` stays at the root. Past the home it climbs to a directory that holds the home, so the path is the home where each segment it then descends through is `*` (`~/../*` and `~/..` read as `~`, `~/../*/*` as `~/*`), and `~/../x` stays a sibling. The kernel reads `..` otherwise only after a symlink; the lexical reading is the one that blocks. A trailing `..` is folded too, though rm refuses it. Nothing is folded across a segment that holds a variable or a substitution, whose directory count is not known. 17-guard.md and commands/guard.md say so and name the residuals: a `..` after a symlink or after a variable's segment, and `~/../?*` beside `/?*`.

A settled LABEL (`resolved:`, `RESOLVED:`, `Deferred:`) is no longer read anywhere in the item: it counts opening a line of the item (its first line or a continuation line), after a closing bold (`**Which surface scaffolds it?** RESOLVED:`), or after a dash (`**Refusal breadth** — resolved:`, `**Relationship to itd-73** (derived versioning) — RESOLVED:`). The same word and colon mid-sentence are prose, so "Which id wins once the split is resolved: the old or the new?" is a question, where the entry's "anywhere in the item" read it as settled and let build start past it. The bold-span marker keeps its reach anywhere in the item.

The template `abcd ahoy` scaffolds (`internal/core/ahoy/defaults/pre-commit`) takes a PROVISIONAL stance on two of the three questions: default or opt-in — opt-in, since nothing runs until the clone sets `abcd.sourcesBinary`; fail open or closed — open, since an unusable opt-in (not an absolute path to an executable regular file) prints one line and the commit proceeds. Only the first question, how a scaffolded hook finds abcd, stays unanswered in the template's own terms, which say it "deliberately does not take" that decision. Both provisional answers stand until the product thinker rules on iss-2609250834251447, and the ruling may replace either. The earlier entry stands as written, since the ledger is append-only (review2-sources finding 5; recorded by lane drainDrift2 of autonomous run A, iss-2609252055533837). - 2026-09-29 — The home the 2026-09-23 entry on third-party interface guidance left "still to be written" is a principle, `.abcd/development/principles/guidance-carries-its-evidence-and-its-purpose.md`, rather than the managed-repository agent conventions (lane triageMajorB, autonomous run A, on iss-2609100506256173; the product thinker's ruling M26 allowed either). A principle states both halves once, in this repository's record, with no change to what abcd writes into a managed repository; carrying the rule into the bundled rules domains that reach every managed repository is a shipped-behaviour change and is left for a planned intent, as is the purpose field on redaction rules that would make the second half checkable. +- 2026-09-29 — An autonomous run keeps at most five sub-agents alive at once, in any mix of roles (the user, directly to the run A orchestrator at 06:53Z, verbatim: "use up to five sub-agents from now on"; recorded by lane remerge-integ17 of autonomous run A). The ceiling of five supersedes the ceiling of four recorded above on 2026-09-24 (02:02Z). Reviews and audits run on Fable stay one at a time; that rule is unchanged. The run still counts a fork toward the ceiling, as its own lane rule, because a fork is an agent alive.

A file renamed into place inside that window was refused on sight with ErrDeclarationSwapped, so the ordinary rewrite a concurrent abcd makes through WriteFileAtomic under the writers' lock made an unlocked reader (layered.Load via oracle.LoadAPI) refuse its own ~/.abcd/config.json. iss-2609290518278152 fixed this in b342b2b29, but in ReadDeclaration, the path read; the integration merge that landed it (24e78506b) kept a07ad672f's descriptor read, readDeclarationIn, which every home-scoped reader calls and which had no retry. The fix never reached a production reader. readDeclarationIn now loops over one vetting and read (readDeclarationInOnce) up to declarationAttempts (8) times, re-running on ErrDeclarationSwapped only. Every attempt runs every guard from scratch: the Lstat (regular file), CallersAlone (no group/other write, owned by this uid), the O_NOFOLLOW open, the descriptor's regular-file and SameFile check, the descriptor's uid, and the caller's deny mask on the descriptor's mode. The bytes returned are always those of a descriptor os.SameFile ties to an Lstat that passed every guard. A replacement that fails a guard is refused by that guard; one still unsettled after the bound is refused as a swap. The directory walk (openHomeScope) is unchanged: a directory level replaced while it is opened is still refused.
