Current authority — 2026-09-24 KST

Status: OPEN / Draft / Proposed / do not merge.

Owned contract

This lane owns only target GHAS/code-scanning analysis-read credential selection after successful CodeQL/SARIF work. It probes the exact target code-scanning/analyses?per_page=1&tool_name=CodeQL endpoint with the reviewed API headers and selects only a configured credential that actually proves analysis-read capability. Failure remains fail-closed.

The selector cannot create target-repository permission. #2276 remains the distinct real-target permission/canary owner and must prove authenticated protected-base and exact-head CodeQL analysis reads. A 401/403/transport error must never be translated into an empty identity set.

Why the earlier restack was required

#2271 moved after Python Security found vulnerable AnyIO 4.14.0 and ordinary-adopted canonical dependency owner #2278 exact 8a5251bf409fe84b3dd0cba1e48992f5b8d9eda5 with the AnyIO 4.14.2 lock. #2275 had still been based on the predecessor #2271 tree, so ordinary two-parent descendant 0d68d7a... repaired that drift without force-push or destructive rebase and retained exactly the three #2275-owned blobs.

Current foundation chain

The old description that treated #2109 as an isolated prerequisite is no longer complete. The current live prerequisite chain is:

  1. fix(opencode): materialize every coverage lock input #2286 exact 42e4198fa012eb24596e7984d77e27f0905348d6 — canonical Required OpenCode coverage-image build-context owner. It breaks the chore(deps): bump anyio from 4.14.0 to 4.14.2 #2278/fix(opencode): materialize every coverage lock input #2286 cycle by ordinary two-parent ancestry, retaining the five coverage-owner paths while carrying chore(deps): bump anyio from 4.14.0 to 4.14.2 #2278's exact AnyIO 4.14.2 dependency blob. It remains Draft with fresh exact-head hosted checks still nonterminal and requires a real coverage-image acceptance plus independent current-head approval.
  2. fix(strix): resolve evidence binder from trusted source #2291 exact 1794626af3473ef23b9c2e678c3f06fd6c11636f — trusted Strix runtime/binder owner. It remains Draft until fix(opencode): materialize every coverage lock input #2286 is verified/protected, then must reconcile by ordinary/non-force ancestry and reacquire Python Security/CodeQL/review evidence.
  3. fix(runtime): gate Draft admission and sandbox evidence #2109 exact 42e3f7a8cbb03b117c898d3e125af87a5c6ce86b — stacked-base/Draft lifecycle admission owner for the heavy required workflows. It is correctly Draft. Its same-head Draft-withdrawal generation terminated SKIPPED as designed, which proves only lifecycle withdrawal, not merge acceptance. After fix(strix): resolve evidence binder from trusted source #2291 becomes protected, fix(runtime): gate Draft admission and sandbox evidence #2109 must reconcile ordinarily, re-enter Ready under policy, and obtain terminal current-head acceptance before integration.
  4. Only after that admission chain is protected may fix(codeql): prove target GHAS analysis-read credential #2275 reconcile onto current canonical/protected ancestry and reacquire the missing Python Security plus all other then-required exact-head checks; CodeQL dispatch cannot prove GHAS identity because target-repo analyses API returns 403 #2276 must independently prove real target analyses-read permission/canary.
  5. The resulting selector/permission authority must then be exercised by a verified chore(foundation): converge AnyIO and CodeQL endpoint repairs #2352 CodeQL lifecycle. Current chore(foundation): converge AnyIO and CodeQL endpoint repairs #2352 proves the scanner and Medium+ SARIF gate can succeed but fails GHAS base/head configuration identity only because code-scanning/analyses returns HTTP 403 Resource not accessible by integration.

This lane must not copy the #2286 coverage repair, #2278 dependency repair, #2291 Strix binder repair, #2109 admission logic, or #2276 permission provisioning.

Evidence boundary

Focused/full evidence and partial hosted receipts from predecessor 572cfed... remain predecessor evidence only. The current 0d68d7a... generation is also not final acceptance because the central admission/foundation chain above is not protected. No qualifying independent approval binds to a future reconciled head.

Keep Draft until the prerequisite chain is protected, this lane is mechanically current with its canonical parent/protected ancestry, #2276 proves real target authority, every exact-head required check is terminal-success, zero valid findings/threads remain, and a qualifying independent approval binds to the final head.

No self-approval, blind rerun, synthetic status, scanner suppression, permission broadening, source-neutral wake/no-op commit, gate weakening, bypass, force-push, destructive rebase, stale parent retention, duplicate central-workflow change, or predecessor-evidence transfer is authorized.

@coderabbitai review

Focused current-head review requested for exact 443c9f6013a831b7e4605532809f7aae375d1019. Please verify the live-failure RCA and RED→repair chain: 8e93ae226b52a4d0456137ae36191241d5c58fe7 → 4c4fff284e6bb58fe738389a647e2a7d1031dd54, stacked ordinary-forward from #2271 exact 2b849c874122961e025c29f7fa0bb697863c3d68.

Review scope: the selector must prove target code-scanning/analyses read capability rather than infer it from a non-empty token; content-only first-token failure must fall through; all-token failure must fail closed; secrets must not be printed; the existing GHAS base/head identity proof, SARIF gate, status semantics, and #2271 repository-admission repair must remain unchanged. Source/static review is not hosted or end-to-end GREEN.

@seonghobae, I found one focused test defect.

  • tests/test_codeql_scan_dispatch_ghas_credential_contract.py, Line 89 expects the fail-closed diagnostic in result.stderr.
  • The selector emits echo "::error::no configured credential can read target CodeQL analyses; ..." to standard output.
  • The focused test_ghas_analysis_read_fails_closed_when_no_candidate_can_read_target test will fail after the selector correctly exits with status 1.

Change the assertion to inspect result.stdout, or redirect the selector diagnostic to standard error. The test should match the existing workflow logging convention.

The static review confirms the intended repair behavior otherwise:

  • HEAD is 443c9f6013a831b7e4605532809f7aae375d1019.
  • The stated parent, RED, and repair ancestry is valid.
  • The selector probes the target code-scanning/analyses endpoint in the required credential order.
  • A rejected content token falls through to later credentials.
  • All rejected credentials cause a hard failure.
  • The identity step uses only steps.ghas_analysis_token.outputs.token.
  • The selected token is masked before it is written to $GITHUB_OUTPUT.
  • The workflow diff is limited to the selector and identity-token handoff. The SARIF gate, status publication, and repository-admission logic are unchanged.

I performed static parsing and shell syntax checks only. I did not execute repository tests or hosted end-to-end checks.

Fresh owner-path correction from Naruon consumer audit: the Current foundation prerequisite section in this PR still names .github#2279@25f83aa..., but live #2279 has ordinary-forwarded to exact 9c19c6e00eafc028068719ab482282c1256f8893. That generation preserves the no-redirect repair and adds executable synthetic-302 coverage through both actual production openers plus the remaining Strix transport seam binding; its current hosted Python Security / CodeQL / Runtime Quality / Semgrep / Security runs are still queued. #2272 has also advanced to e0b6e70f8c8ea87648af2fc2d34dd43ffa625beb on the sibling Pages/origin-hardening lane.

No #2275 source mutation is needed for this observation: keep capability-selector source stable and restack only after the live foundation is accepted. Do not treat the stale 25f83aa... receipt or any predecessor checks as foundation acceptance; #2276 real target code-scanning/analyses permission/canary remains independently required.

Traceability/stack-currentness is RED on exact fc9c5537d9910f0536dab2aaf52888078c8ead64.

The implementation boundary here is still correctly stacked on #2271 and should remain source-stable, but the Current foundation prerequisite section is stale: it names .github#2279@25f83aaee9eb97e423f6ef2467e722035bc2e362 and that generation's run IDs as current. Fresh canonical-owner read shows #2279 has ordinary-forwarded to d63d7e96426803d33e79c62e7317776f3dc1851c. That current successor preserves the URL/no-redirect source repair and adds executable production-opener synthetic-302 proof plus published-lineage repair. Its natural exact-head runs are still nonterminal: Agent Review Runtime Quality 35436033522 pending; Python Security 35436033535, CodeQL 35436033515, SAST 35436033530, Security Scan 35436033546 queued.

Minimum repair is coordination metadata only. Currentize this body to the live #2279 owner or, better, record the stable dependency on canonical #2279 and require a fresh owner read immediately before restack/acceptance instead of versioning volatile foreign SHAs/runs as durable truth. Do not wake this head, copy #2279 code here, or infer foundation GREEN from predecessor runs.

The valid order remains #2279 accepted/landed → #2271 ordinary-forward adoption + fresh exact-head acceptance/landing → this #2275 non-force restack preserving the credential-capability selector → focused selector contracts + hosted checks + independent review → #2276 real target analysis-read authority → unchanged canary end-to-end dispatch. Until then this Draft is correctly blocked.

Ordinary two-parent integration of #2271 into stacked GHAS credential owner #2275. Preserves the credential-routing delta while carrying the canonical URL/redirect foundation and stderr-bound repository-admission repair. Local focused result: 164 passed; full result: 3,377 passed, 28 skipped, 40 subtests.

Exact-head coordination review @ 3aad8cbf74e609cfa951c25c6644a8b1ee489304 — Prerequisite-currentness / stacked-ancestry / evidence-transfer gate: FAIL; the GHAS capability-selection source delta itself is not rejected.

Live parent #2271 is now 8aff1a6a581613709c01747fe68c1f7523fe84da on #2279 d1e4380c15e948aaf104d46aa134fa614058782a. This PR still has base SHA 055ee9b9587512fdb999d1c847a4e93828475439 and its current body/ordinary-merge claim is anchored to that superseded #2271 generation. Therefore this exact tree is not the current stacked successor even though its own credential-capability delta remains valid.

RED acceptance: compare live #2271@8aff1a6a... against this exact tree and fail while any valid repository-identity / stderr-bound / inherited #2279 URL-redirect / evidence-owner delta is absent. Also bind the stack contract to the actual current parent ref/SHA rather than historical prose. The existing 164-focused / 3,377-full local results and any hosted runs for 3aad8cb... remain evidence for this old-parent generation only; they cannot transfer after ancestry repair.

GREEN: ordinary/non-force adopt the current #2271 generation while preserving this PR's unique code-scanning/analyses capability-selection RED/GREEN and doctoring. Then reacquire exact-head hosted CodeQL/Security/Semgrep plus qualifying independent review and the unchanged-target end-to-end canary. Issue #2276's real 401/403/install-permission boundary remains separately required; successful token selection must not be treated as permission creation.

Do not force-push/rebase, copy selected parent files by hand, wake with a no-op commit, rerun OriginWeave solely to manufacture freshness, or transfer predecessor GREEN.

Preserve concurrent #2279 foreign-evidence authority through current #2271 while retaining #2275 GHAS credential routing. Focused stack result: 165 passed; full result: 3,378 passed, 28 skipped, 40 subtests.

Exact-head test-contract review at f54aeb6f5c6b30534ee2f12e040208e098957b4b (tree fa4b8fc8b09026946d8b0cf9655622ec294d32f6; COMMENT, not approval).

A mutation review exposed a real vacuous-proof gap: replacing the production probe's repos/${TARGET_REPOSITORY}/code-scanning/analyses?... target with generic repos/${TARGET_REPOSITORY} left the prior credential contract GREEN (3 passed). The fake gh checked only its first api argument and token ordering, so it did not prove that the selected token had the claimed GHAS analysis-read capability.

The exact-head repair changes only that focused test boundary. Fake gh now requires the reviewed Accept header, API version, argument cardinality, and exact target code-scanning/analyses?per_page=1&tool_name=CodeQL endpoint before it can accept a credential. Production workflow/credential order and the fail-closed identity verifier are unchanged.

Verification:

  • focused credential contract: 3 passed after restoring the production analyses endpoint;
  • combined owner/prerequisite/credential stack: 165 passed with warnings-as-errors;
  • full GITHUB_ACTIONS=true suite with Runtime Quality hashed dependencies: 3,378 passed, 28 skipped, 40 subtests;
  • git diff --check: PASS;
  • ordinary fast-forward compare from f7ce53fd...: ahead 1 / behind 0, one test path, +6/-0;
  • unresolved live threads: 0.

Hosted exact-head CodeQL/SAST/Security runs are queued, Runtime Quality/Python Security and qualifying independent approval are not yet present, and #2276 still owns real target installation permission. Keep Draft/Proposed; this evidence is not merge authority.

Post-review mutation confirmation for exact test contract f54aeb6f...: after the repair, changing only the production probe target back to generic repos/${TARGET_REPOSITORY} produces the intended RED (1 failed, 2 passed) at the positive capability-fallback case. Restoring the exact code-scanning/analyses?per_page=1&tool_name=CodeQL endpoint returns 3 passed. This confirms the new assertions are causal rather than documentation-only.

Fresh prerequisite correction — 2026-09-19 KST: #2279 is no longer an unlanded prerequisite. Protected main advanced to merge commit e6334e229581a918e2f22de18733b76fa65d7e71, whose second parent is #2279 exact d1e4380c15e948aaf104d46aa134fa614058782a. #2271 remains Draft at 8aff1a6a581613709c01747fe68c1f7523fe84da, now based on protected main@e6334e...; this #2275 head remains f54aeb6f5c6b30534ee2f12e040208e098957b4b stacked on #2271. Therefore the remaining foundation sequence is current-base #2271 acceptance → this selector's exact-head hosted/current-head review → distinct #2276 real target analysis-read permission/canary. Do not keep #2279's former open-PR acceptance as a live blocker or transfer its predecessor receipts; its valid source contract is now protected ancestry.

Record #2271a0e1424 as ancestry while preserving the verified #2275 tree; predecessor checks and reviews do not transfer.

Exact-head stack reconciliation review at 572cfed270ae3b3cd38faca4d97ce028093e5373 (COMMENT, not approval). This ordinary two-parent successor records prior #2275 f54aeb6f5c6b30534ee2f12e040208e098957b4b and current parent #2271 a0e1424de409ec474e7bc6e9f91a9e99b8a0915e. The tree remains byte-identical at fa4b8fc8b09026946d8b0cf9655622ec294d32f6; compare from the prior head has no changed files, while compare from the current parent is ahead 10 / behind 0 and exposes only the three owned GHAS credential-routing paths. Branch movement was fast-forward-only (force=false). Fresh CodeQL 35450109340, SAST 35450109418, and Security 35450109533 runs are queued and are not GREEN. Keep Draft until #2271 acceptance, #2276 real target analysis-read permission, terminal exact-head checks, and qualifying independent review; no predecessor evidence transfers.

Current-head hosted-evidence correction for exact 0d68d7a8435652edc288d7bb3dfb06a7c8a59eb6: the complete pull_request workflow inventory is currently exactly three runs — CodeQL 35480836023 pending, SAST 35480836004 cancelled, Security Scan 35480836015 cancelled. No Python Security generation exists on this head.

That absence is not evidence that Python Security is unnecessary or GREEN. Protected .github/main@e6334e229581a918e2f22de18733b76fa65d7e71 still declares python-security.yml with pull_request.branches: [main, master, develop], while this PR correctly targets stacked base fix/codeql-dispatch-repository-identity. Canonical admission repair #2109 already removes that PR base-name filter without widening push policy; live canary handoff is recorded there as comment 5747515934.

Keep this head Draft. Do not retarget solely to manufacture a run, copy the central workflow, no-op wake, or manually rerun unrelated workflows. After the central admission repair is normally accepted, this lane must materialize a fresh Python Security receipt on a valid stacked base in addition to its CodeQL/SAST/Security and real target-analysis-read acceptance.

Canonical admission prerequisite identity update — 2026-09-20 KST.

The source finding in this PR is unchanged, but the live #2109 prerequisite identity has moved. #2109 is now exact 42e3f7a8cbb03b117c898d3e125af87a5c6ce86b, tree 0dcd95f1838f68d677249284e240caf3fc63849d, OPEN / Draft / mergeable on #2291. It is 2 commits ahead of the previously cited f62172a... with zero file diff and the same tree; the intervening stale-generation RED was withdrawn as authority-conflicting.

Current exact #2109 Draft lifecycle evidence is stronger than the stale identity: Python Security, SAST, Runtime Quality, and Security Scan completed skipped, while CodeQL has zero jobs. That confirms runner-free Draft admission on the current tree, not Ready-path acceptance.

Accordingly this #2275 lane must still wait for the canonical #2109 admission contract (or a verified successor) to become accepted/protected, then naturally reacquire Python Security on the stacked base. Do not copy the base-filter/lifecycle workflow delta into #2275, and do not treat tree identity or Draft skip receipts as transferable hosted acceptance.

Central admission owner currentness handoff — 2026-09-20 KST

The parent/child topology in this PR is unchanged: current exact 0d68d7a8435652edc288d7bb3dfb06a7c8a59eb6 remains 11 ahead / 0 behind exact parent #2271 8da5f48fa0438ff33c766f03325f6e7f2a77dd9d, with only the three GHAS credential-routing paths as child delta.

One authority pointer in the body is stale. Canonical stacked-base/Draft admission owner #2109 is now exact 42e3f7a8cbb03b117c898d3e125af87a5c6ce86b (tree 0dcd95f1838f68d677249284e240caf3fc63849d), after ordinary-forward withdrawal of an authority-conflicting experimental oracle. Its current Draft generation has Runtime Quality 35490837616, Python Security 35490837682, SAST 35490837549, Security Scan 35490837568, and CodeQL 35490837629 all terminal skipped. Those receipts prove Draft gating, not hosted acceptance.

The current #2275 finding therefore remains exactly scoped: this stacked base has SAST 35480836004 and Security 35480836015 terminal cancelled, CodeQL 35480836023 pending, and no Python Security run was generated under protected-main base filtering. Do not retarget, copy #2109 workflow source, or synthesize a status. Acceptance still requires the central admission contract to become protected under reconciled Actions policy, followed by a naturally generated exact-head Python Security lane on the valid stacked base.

Prerequisite lifecycle update (2026-09-20): canonical stacked-base admission owner #2109 remains exact 42e3f7a8cbb03b117c898d3e125af87a5c6ce86b, but is Draft again after a same-head Ready canary. That Ready generation successfully created CodeQL 35494752040, Python Security 35494752070, SAST 35494752067, Runtime Quality 35494752102, and Security 35494752139; converting #2109 back to Draft then cancelled all five queued heavy runs without changing source/tree, with the new converted-to-draft generation correctly skipping heavy work.

For #2275, this improves confidence in the prerequisite contract but does not transfer evidence. Keep #2275 blocked on accepted/protected #2109 (or a fully verified successor), then reacquire Python Security and Runtime Quality on #2275's own exact head. Do not interpret #2109's canary as #2275 acceptance and do not add a local duplicate admission workaround.

Fresh real producer evidence now exercises the exact GHAS credential-selection boundary this PR owns.

.github#2352 producer 35841640640 completed both language scans on exact head f1a8dc813e6dba4e4905bf3e1b770b6d44344944 far enough to prove CodeQL itself is clean: Python and Actions both completed analysis and passed the Medium+ SARIF gate. Both then fail only at Verify GHAS base/head CodeQL configuration identity because the credential presented to the code-scanning analyses endpoint receives HTTP 403 Resource not accessible by integration.

This validates #2275's fail-closed selector requirement and shows protected main still lacks an analysis-read-capable credential. It does not justify copying a permission workaround into #2352 or BandScope. Keep #2275 as the source selector owner and #2276 as the real target-permission/canary owner. After the prerequisite stack is ordinarily reconciled, the acceptance criterion should include this exact endpoint proving base/head analysis reads before the selector admits a credential; clean SARIF alone is insufficient.
