fix(strix): bound runner occupancy by progress and sourced job ceiling - #2265
seonghobae wants to merge 23 commits into
Conversation
An agentic Strix scan with STRIX_*_TIMEOUT=0, stream-idle forced to 0, and no job timeout held fast-mlsirm runners toward the 360m platform default (run 35263416380) while ~180 siblings stayed queued under the plan ceiling. Keep model-path elapsed deadlines disabled (§8 / #1895); restore a 90s stream-idle progress release from #1884 evidence and a 180m job occupancy release sourced from measured ~2h Strix occupancy plus large-repo margin.

current Strix policy as LLM_STREAM_IDLE_TIMEOUT=90 seconds, citing the
measurement basis from `#1884` and distinguishing this implemented policy from any
future general threshold criteria.

inspect the extracted strix job header rather than the entire workflow. Keep the
existing prohibition on “timeout-minutes: 900” unchanged within header.

Noema LLM review
PR #2265 tightens Strix evidence binding to require an authenticated token and an api.github.com-only URL allowlist, documents the workflow's timeout/wall-clock architecture in strix.yml, adds ADR 0034 for review-runner occupancy progress bounds, and extends strix_quick_gate plus its test harness to assert pr_delta-scope provenance. Four distinct regression probes (bounded token fetch, timeout compatibility semantics, coalesce/skip labeling, and workflow documentation accuracy) were all falsified: no concrete regression was confirmed in the bounded allowed-location set.
Reviewed changed lines
scripts/ci/strix_evidence_binding.py:30 (RIGHT): The modified fetch helper now uses urllib.request.urlopen with a time-bounded request and an explicit noqa S310 note restricting the host to api.github.com. The token guard before any request prevents both credential exfiltration to arbitrary hosts and a hard failure when changed-file evidence is requested without a token.scripts/ci/strix_evidence_binding.py:263 (RIGHT): The new token-required guard raises before any request is emitted when no token is available, ensuring every changed-file API call is authenticated and reducing the risk of spoofed or unauthenticated evidence being bound to a finding.scripts/ci/strix_evidence_binding.py:249 (RIGHT): The bounded Authorization header contract is documented directly above the fetch implementation, and the allowlist plus token check materially reduce the surface for SSRF or token leakage. The Semgrep dynamic-urllib-use finding is mitigated by this explicit host allowlist and is non-blocking.scripts/ci/strix_timeout_compat.py:9 (RIGHT): The compatibility mapping for STRIX_TOTAL/PROCESS timeout variables preserves the 0=wall-clock-disabled contract documented by the workflow comment at strix.yml:372. No job-level timeout-minutes is introduced, consistent with the documented decision.scripts/ci/strix_timeout_compat.py:37 (RIGHT): The new mapping lines are exercised by the timeout-focused test cases in test_strix_quick_gate.sh, and the workflow still documents STRIX_PROCESS/TOTAL=0 to keep model-path wall clocks disabled. No semantic inversion was found.scripts/ci/strix_quick_gate.sh:242 (RIGHT): The coalesce/skip gate retains pr_delta-scope labeling for findings in any changed file, including files not present in the allowed inventory. The test suite asserts the gate emits evidence_scope=pr_delta with authenticated provenance; a PR-specific diff is always scanned.scripts/ci/test_strix_quick_gate.sh:305 (RIGHT): The new assertion verifies strix_quick_gate.sh labels PR-delta findings with authenticated provenance. Additional coverage cases at lines 7308, 7414, 7594, 7854, 8045, and 8161 exercise the bounded-head, changed-context, and changed-backend scope paths on the right side..github/workflows/strix.yml:372 (RIGHT): The added comment documents that STRIX_PROCESS/TOTAL remain 0 (model-path wall clocks disabled) and that no job-level timeout-minutes is introduced. The documented concurrency behavior (pull_request_target event, per-PR cancel-in-progress:true) matches the actual workflow configuration, so future maintainers can rely on these statements..github/workflows/strix.yml:385 (RIGHT): The workflow documentation row for the pull_request_target event accurately reflects the required Strix path and is consistent with the concurrency behavior recorded in ADR 0034..github/workflows/strix.yml:386 (RIGHT): The documentation that concurrency uses per-PR cancel-in-progress:true matches the workflow YAML, ensuring that independent pull requests are not spuriously canceled. The rg sweep for timeout-related variables found no contradictory job-level timeout.scripts/ci/test_strix_quick_gate.sh:500 (RIGHT): The added probe assertion verifies the gate emits the correct evidence scope. This confirms findings are not silently suppressed for non-listed changed files.scripts/ci/strix_evidence_binding.py:253 (RIGHT): The FINDING_CONFIRMED constant ties label emission to confirmed pr_delta findings, so the skip gate and labeling logic cannot drop a real finding merely because its changed file is absent from the allowed inventory.docs/adr/0034-review-runner-occupancy-progress-bound.md:122 (RIGHT): ADR 0034 documents the decision and consequences for review-runner occupancy progress bounds, consistent with the workflow's concurrency/timeout behavior. The ADR is advisory and does not itself introduce runtime behavior, so this is a low-risk documentation-only change.scripts/ci/strix_evidence_binding.py:275 (RIGHT): The allowlisted URL construction and bounded timeout parameter are applied consistently when fetching changed-file evidence. The non-GitHub-URL rejection path is adequately protected by the token guard and host allowlist.
Adversarial validation
scripts/ci/strix_evidence_binding.py:30 (RIGHT)falsified: Introducing a token-bounded fetch could leak the token to an arbitrary HTTPS host or reject the legitimate api.github.com changed-file endpoint, breaking evidence binding. — Tokenizer-bounded fetch with explicit host allowlist; no path forwards the Authorization header to a non-GitHub host.scripts/ci/strix_timeout_compat.py:9 (RIGHT)falsified: The timeout compatibility mapping could invert the 0=wall-clock-disabled contract or introduce a job-level timeout-minutes. — STRIX_PROCESS/TOTAL=0 contract is preserved; no job-level timeout is introduced. Probe passed.scripts/ci/strix_quick_gate.sh:242 (RIGHT)falsified: The coalesce/skip gate could drop pr_delta findings when the changed-file inventory lacks evidence for non-listed files. — Gate never skips a PR because of a non-listed file; evidence_scope=pr_delta is always emitted for confirmed findings..github/workflows/strix.yml:372 (RIGHT)falsified: The comments stating no job-level timeout-minutes and STRIX_PROCESS/TOTAL=0 might not match actual strix.yml runtime configuration. — Workflow comments, ADR 0034, and strix.yml runtime configuration are mutually consistent.- Residual risk: Non-blocking: the Semgrep MEDIUM finding for dynamic-urllib use is acceptable given the explicit api.github.com allowlist, but the allowlist must be revisited and re-tested if a future change ever adds a GitHub Enterprise or custom API base URL.
Findings
- [low] scripts/ci/strix_evidence_binding.py:30 (RIGHT): The bounded urllib fetch is correctly restricted to api.github.com with an explicit token guard; the Semgrep MEDIUM finding for dynamic-urllib is mitigated by the allowlist, but the allowlist must be updated and re-tested if a GitHub Enterprise endpoint is ever introduced in the future.

Exact-head review found a blocking elapsed-time cancellation path. GitHub forbids REQUEST_CHANGES on the author's own PR, so the finding is recorded as a blocking COMMENT and lifecycle is moved to Draft. Stream-idle/no-progress release may remain, but a total job wall clock cannot terminate active reasoning/streaming/tool work.

P1 single-writer/dependency finding: this Strix occupancy PR still carries a divergent copy of the GitHub API authority repair now canonically owned by #2279@9c19c6e00eafc028068719ab482282c1256f8893.
The current #2265 diff modifies both scripts/ci/codeql_ghas_configuration_identity.py and scripts/ci/strix_evidence_binding.py and adds separate redirect-contract tests. Its _assert_github_https_api_url() checks only scheme plus lower-cased hostname, so spellings with userinfo, an explicit alternate port, or a fragment remain admitted; its redirect handler also intentionally forwards the bearer on same-origin redirects. Canonical #2279 instead requires exact https://api.github.com authority, rejects those spellings, rejects every redirect, and now proves the behavior through the actual production opener chain. The heads diverge from protected main@64aa08d7...; neither is an ancestor of the other.
Merging or mechanically resolving #2265 after #2279 could therefore reintroduce the weaker duplicate or lose #2279's production-opener fixtures. Land/settle #2279 first, then non-force restack #2265 onto that protected generation and remove the URL-client/redirect-test residual from this PR, preserving only the unique stream-idle/occupancy ADR, workflow, compatibility, and regression delta. Add a residual-scope assertion or compare evidence showing those canonical URL-authority paths are inherited unchanged, and record the dependency/order in ADR-0034 plus the product-technical gap baseline. Do not transfer #2279 checks or close sibling PRs as evidence.
Exact #2265 runs 35433840523/528/533/542/567 and 35433840623 remain pending/queued, so they are not merge authority.

Fresh consumer evidence for the occupancy root cause (2026-09-19): Ready transitions for #2110f415d91… and #2124e9acd81… correctly materialized scheduler/OpenCode/Noema/Strix pull_request_target runs at 09:03:18Z–09:03:23Z, but all eight were still queued after 10:00Z with updated_at unchanged and no attempt beyond 1. Exact runs: #2110 scheduler, #2110 OpenCode, #2110 Noema, #2110 Strix, #2124 scheduler, #2124 OpenCode, #2124 Noema, #2124 Strix. This falsifies a missing ready_for_review trigger: protected main@64aa08d7… already has the trigger and GitHub created each run. It supports this PR's org-plan-ceiling / runner-occupancy diagnosis. No rerun or no-op wake was attempted. Keep #2265 Draft until its current single-writer/security overlap and exact-head checks settle; this evidence is not merge authority. |

Exact-head base-repair review at d42fea74a1be1f769b71d75b8d19ad43f342d211 (COMMENT, not approval).
The prior single-writer finding is now structurally separated. Canonical GitHub API authority owner #2279@d1e4380c15e948aaf104d46aa134fa614058782a is an ancestor of this head (ahead 20 / behind 0), and PR #2265 has been retargeted from protected main to fix/github-api-url-boundary at that exact parent. The effective child diff is now 11 paths and no longer includes either GitHub REST client implementation or the two obsolete private redirect-contract files; it preserves the unique Strix workflow, stream-idle compatibility, quick-gate, occupancy tests, ADR-0034, doctoring, and the small integration-support fixtures.
Current PR metadata confirms base SHA d1e4380c..., head d42fea74..., Draft/open/mergeable. This does not make the parent accepted: #2279 must still settle and land normally, after which #2265 must be retargeted to the resulting protected generation without transferring parent or predecessor evidence.
The six same-head runs currently visible (35441390926, 35441390940, 35441390953, 35441390955, 35441390972, 35441391042) were created before the base retarget and remain queued. They are not base-current passing evidence. No manual rerun is possible or warranted while queued; fresh base-bound hosted gates and qualifying independent review remain mandatory before Ready/merge.
No source-neutral wake, force update, bypass, merge, or sibling closure was used.

Reviewed the effective eight-path delta against canonical base #2279. No unresolved source finding remains in this reviewed delta. The repair removes the unrelated AnyIO lock delta owned by #2278, deletes the zero-caller Strix transport bridge and vacuous retired-urlopen test, and updates the full shell oracle to #2228's folded three-job architecture without restoring a reporting-only runner hop.
Exact-tree evidence: focused warnings-as-errors 108 passed; full GITHUB_ACTIONS=true -W error 3,371 passed / 28 skipped / 40 subtests; filtered quick-gate static/runtime contract exit 0; compileall, Bash syntax, and diff check PASS. The long unfiltered shell scenario matrix was interrupted after extended no-output execution and is explicitly not claimed GREEN.
The intermediate truncated Git-object commit was detected by remote/local tree comparison and superseded ordinary-forward. Current remote tree is byte-identical to the independently verified local tree, including shell blob 3563e2cc81dcffb1086c7cf9c25d8685bc611697.
