fix(codeql): bootstrap versioned dispatch handler

[seonghobae]

Current canonical state — 2026-09-17

This Draft remains the canonical landing vehicle for the versioned CodeQL dispatch handler. Protected .github/main is exact 4e56ff0fd10e8d56e9af273881a7eb65d7e4f513; current branch head is exact 0e9412f93bb9d4a08a689f62a563dc666ae91f88. Fresh compare is 57 ahead / 0 behind, merge base equals protected main, GitHub reports the PR mergeable, and the effective delta is now eight CodeQL/bootstrap-owned paths.

Current-generation reconciliation repair

Review 5237380716 on predecessor 6be76f6594b784d93d7be33fa1677b2419bf07b2 found one current-base contract defect: tests/test_opencode_agent_contract.py had restored obsolete assertions for a separate coverage-source-tree job even though protected main already folded those reads into validate-pr-metadata, while this branch does not modify .github/workflows/opencode-review-dispatch.yml. The branch test therefore expected a job absent from the inherited workflow.

Ordinary-forward fix 0e9412f93bb9d4a08a689f62a563dc666ae91f88 adopts protected main's test blob unchanged. The path disappears from the PR delta; no CodeQL/bootstrap behavior, protected OpenCode workflow, gate, or permission contract was weakened. No force-push or destructive rebase was used.

Handler contract retained

• codeql-scan-dispatch.yml accepts legacy codeql-scan and staged codeql-scan-v2 events.
• Legacy payload/status contracts remain intact while v2 binds producer source, ordered merge parents, nested PR-head provenance and schema "1" for nested-rerun authority.
• Matrix shards remain read-only consumers; one post-matrix coordinator owns settlement/mutation.
• Required-run attempt 48 stops before mutation; denied-credential stdout is discarded so successful fallback evidence cannot be contaminated.
• v1 and v2 share one concurrency owner; v1 removal remains gated on protected v2 integration, in-flight drainage and zero live callers.

Exact-head acceptance boundary

The source reconciliation is not terminal acceptance. Exact 0e9412f9... naturally generated CodeQL PR 35236110056, SAST Semgrep 35236109832, Security Scan 35236109955, Python Security 35236109883, and Agent Review Runtime Quality CI 35236110143; all are currently queued. Formal review history contains no qualifying independent APPROVED for this exact head. Predecessor checks/reviews do not transfer.

Keep Draft until this unchanged exact head reaches terminal required checks plus qualifying independent approval. Synthetic status, self-approval, administrator bypass, source-neutral wake, blind/manual rerun, force push, destructive rebase, gate weakening or mutable dependency substitution is not acceptance.

Post-protected integration canary boundary

The independent linux-cluster-ops#306 canary remains separate: OIDC and App-token exchange succeeded, but the App credential received HTTP 403 while creating repository_dispatch in ContextualWisdomLab/.github. After #2106 normally reaches protected main, downstream #2040 must ordinary/non-force reconcile onto that protected tip and a fresh unchanged external canary must prove exactly one authenticated central dispatch plus terminal settlement of the original required CodeQL workflow. #2040 must not land first.

📝 Walkthrough

Walkthrough

CodeQL 디스패치는 legacy-v1과 codeql-scan-v2를 지원한다. v2는 PR head와 producer merge commit을 검증한다. settle-required-run job은 handler 증거를 확인한 뒤 required run 전체를 재실행한다.

Changes

CodeQL 디스패치 제어 평면

Layer / File(s)	Summary
버전 프로토콜 및 입력 계약 .github/workflows/codeql-scan-dispatch.yml, tests/test_codeql_scan_dispatch_workflow_contract.py	codeql-scan legacy-v1과 codeql-scan-v2를 구분한다. v2의 pr_head, producer_source_sha, rerun_request, required job identity를 검증한다. 관련 계약 테스트를 추가했다.
스캔 권한 및 상태 receipt .github/workflows/codeql-scan-dispatch.yml	scan job의 actions 권한을 read로 제한한다. SARIF 업로드와 handler 상태를 검증한다. legacy-v1과 v2에 다른 status context와 receipt 설명을 사용한다.
Required run 전체 정산 .github/workflows/codeql-scan-dispatch.yml, tests/test_codeql_scan_dispatch_workflow_contract.py	매트릭스별 job 재실행을 제거한다. settle-required-run이 PR, required run, jobs, handler gate, SARIF artifact를 검증하고 rerun-failed-jobs 또는 rerun을 한 번 호출한다.
아키텍처 기록 및 계약 검증 docs/adr/..., docs/doctoring/..., docs/product-technical-gap-baseline.md, CHANGELOG.md, tests/test_scheduler_and_codeql_dispatch_runner_image_contract.py	새 프로토콜, credential fallback, rerun schema, attempt 예산, settlement 동작을 문서와 계약 테스트에 반영한다.

Exact-head control-plane review at ae3d0a5c6104bc084735827165a081a6af9ce5af.

No unresolved source finding in the seven-path bootstrap delta:

• legacy codeql-scan remains byte-contract compatible at the event/title/status boundary;
• v2 provenance binds producer source, base, head, and ordered merge parents;
• v1/v2 share one repository/PR concurrency group;
• matrix shards hold only actions:read;
• only the post-matrix settlement holds actions:write, revalidates the live PR and exact required-run/job/gate/SARIF evidence, then issues at most one run-wide rerun;
• v1 deletion is gated by protected v2 landing, in-flight v1 drainage, and zero live callers.

Independent local exact-tree evidence: 3067 passed, 1 skipped, 21 subtests; py_compile and diff check PASS; all seven remote blob SHAs match the verified local files. This COMMENT is not a qualifying approval. Keep Draft/Proposed until hosted exact-head Checks and an independent qualifying reviewer complete.

[seonghobae]

Exact-head hosted evidence receipt for ae3d0a5c6104bc084735827165a081a6af9ce5af:

• Runtime Quality 34686129456: queued
• CodeQL 34686129399: queued
• SAST 34686129423: queued
• Python Security 34686129496: queued
• Security Scan 34686129509: queued

These are current-head runs but not terminal GREEN evidence. Draft/Proposed and no auto-merge remain correct while hosted checks and qualifying approval are outstanding.

[seonghobae]

Ready-for-review admission at unchanged exact head ae3d0a5c6104bc084735827165a081a6af9ce5af created replacement security evidence. The Draft-event runs for CodeQL/SAST/Python Security/Security were cancelled by lifecycle concurrency and are not inherited.

Current runs:

• Runtime Quality 34686129456: queued
• CodeQL 34686191784: queued
• SAST 34686191615: queued
• Python Security 34686191627: queued
• Security Scan 34686191666: queued

Ready is review admission only. Exact-head hosted GREEN and qualifying approval remain merge gates; auto-merge is not enabled.

[seonghobae]

Fresh cross-repository canaries for the versioned CodeQL bootstrap/settlement acceptance. These are unchanged product heads; no leaf no-op retrigger or synthetic status was used.

1. ContextualWisdomLab/appguardrail#1131

• exact head: 324f07b3385ef3e3684e58e77892549cce469232
• required CodeQL run: 34685949408
• Python compatibility consumer: start 2026-09-12T09:30:34Z, terminal failure 09:32:56Z
• Actions compatibility consumer: start 09:30:41Z, terminal failure 09:32:56Z
• authoritative dispatch: did not start until 09:34:31Z; completed SUCCESS 09:34:39Z
• same exact head: Tests, Security Scan, SAST and repository-specific controls are GREEN.

2. ContextualWisdomLab/html4tree#682

• exact head: 36510f48d859e8fa41a235e9130f4e6f64142087
• required CodeQL run: 34657409995
• Actions compatibility consumer: start 2026-09-11T23:40:50Z, terminal failure 23:43:28Z
• Java/Kotlin compatibility consumer: start 23:41:06Z, terminal failure 23:43:40Z
• authoritative dispatch: start 23:44:51Z, completed SUCCESS 23:44:58Z
• same exact head: repository CI, Security Scan and SAST are GREEN.

Both reproduce producer-after-consumer settlement rather than a leaf CodeQL source finding. GREEN acceptance for the protected bootstrap / later v2 producer rollout should require the authoritative versioned handler receipt to be discoverable, or the consumer to bounded-wait/reconcile it, before compatibility settlement for exact {repository, PR, head_sha, base_ref, base_sha, required_run, language}. Genuine dispatch failure/cancel, stale or malformed identity must remain fail-closed.

[seonghobae]

Evidence correction for review 5186015459 and the earlier receipts: 3071 passed, 1 skipped, 36 subtests is the authoritative remote-tree-equivalent result.

The earlier 3067/1/21 run covered the bootstrap files on the predecessor local checkout but did not yet include the six-path protected-main README-standard advance. I reconstructed every added/modified protected-main path in the verification worktree, proved their blob SHAs equal #2106, kept all seven bootstrap blob SHAs equal, and reran the complete suite. py_compile and git diff --check also pass. No hosted result is inferred from this local proof.

[seonghobae]

Hosted exact-head progress at unchanged ae3d0a5c6104bc084735827165a081a6af9ce5af:

• Runtime Quality 34686129456: GREEN; scheduler/contextual-orchestrator repair contracts and consolidated workflow contract completed successfully.
• Security Scan 34686191666: GREEN; gitleaks, Trivy, and Scorecard jobs completed successfully.
• CodeQL 34686191784, SAST 34686191615, and Python Security 34686191627 remain queued and are not treated as passing.
• Qualifying approval remains absent; auto-merge remains disabled.

Fresh downstream canary supporting this bootstrap prerequisite: ContextualWisdomLab/TEPP#494@67d1c4e3874cf876209459a4d76a472e41102d62 has all peer product gates GREEN while Required CodeQL still demonstrates producer-after-consumer settlement.

TEPP run 34684972560:

• language detection 103530276887 GREEN;
• Python consumer 103530319410 read the current-head verdict successfully, then failed enforcement at 2026-09-12T09:10:23Z;
• Actions consumer 103530319421 read the verdict successfully, then failed enforcement at 09:12:53Z;
• producer dispatch 103531031765 did not start until 09:16:55Z, after both consumers had already terminally failed, then completed GREEN at 09:17:00Z.

Same TEPP exact head: Rust Foundation 34684972551, Documentation Quality 34684972571, Security 34684972573, and Semgrep 34684972550 are GREEN. This isolates a real central lifecycle/settlement failure and provides a downstream acceptance canary for the v2 bootstrap. TEPP will not work around it with sleeps, no-op pushes, synthetic receipts, or weakened run identity.

@coderabbitai autofix

Current head guard: act only if PR #2106 is still exactly c81e39ce040bb174c6ffb12670cadc3d0e0878a9 and docs/product-technical-gap-baseline.md is still blob 43027eef506ed136bc394981f7f342e364c068ca. If either moved, stop and re-read/adapt; do not overwrite concurrent protected-main reconciliation.

Apply only these two literal token replacements in docs/product-technical-gap-baseline.md, preserving every other byte/line and avoiding Markdown reserialization or broad formatting changes:

1. contextual-orchestrator#1149@684cf28f → ContextualWisdomLab/contextual-orchestrator#1149@684cf28f
2. fast-mlsirm@09f762d → ContextualWisdomLab/fast-mlsirm@09f762d

This is the existing executable RED owned by tests/test_product_technical_gap_baseline_repository_identity_contract.py; do not change or weaken that test. Commit the minimal source repair normally on fix/codeql-versioned-handler-bootstrap, no force/rebase/no-op changes. The resulting diff for the baseline must be exactly the two owner-prefix insertions.

[seonghobae]

Current head and source are unchanged at c81e39ce040bb174c6ffb12670cadc3d0e0878a9, and docs/product-technical-gap-baseline.md still contains exactly the two legacy durable identities contextual-orchestrator#1149@684cf28f and fast-mlsirm@09f762d. Current repository-identity contract therefore remains intentionally RED; current owned workflows are also still nonterminal.

@coderabbitai autofix

Work only if PR head is still exactly c81e39ce040bb174c6ffb12670cadc3d0e0878a9. On branch fix/codeql-versioned-handler-bootstrap, modify only docs/product-technical-gap-baseline.md and only these two literal tokens:

• contextual-orchestrator#1149@684cf28f → ContextualWisdomLab/contextual-orchestrator#1149@684cf28f
• fast-mlsirm@09f762d → ContextualWisdomLab/fast-mlsirm@09f762d

Do not reflow, reserialize, rewrap, normalize whitespace, reorder tables, or touch any other byte in this hot document. Do not modify or weaken tests/test_product_technical_gap_baseline_repository_identity_contract.py. If head or target blob has moved, stop and re-read rather than applying stale text. Push a normal fast-forward descendant only; no force/rebase. After the exact two-token descendant exists, let the normal PR workflows validate it.

[coderabbitai]

Autofix skipped. No unresolved review comments with fix instructions found.

[seonghobae]

Current exact still has one executable documentation-contract RED. I am opening this as an owner-local repair finding rather than weakening or bypassing the contract.

🤖 Completed: Fix CodeRabbit issues in PR #2106 — View commit 653466d

[seonghobae]

Fresh owner-path check after the latest protected-main movement: .github/main is now exact 4e56ff0fd10e8d56e9af273881a7eb65d7e4f513 (merged #2157), while this canonical bootstrap remains 86dd9ed3d20aa45c42f88e47bf0739caf982e851 on merge base 4fda7f504e58f72f0d9120c83b7da2b5cc824f25. Fresh compare is diverged: 54 ahead / 4 behind, with the same nine CodeQL/bootstrap effective paths. Treat the four intervening protected commits as owner truth to ordinary/non-force adopt; do not reuse 86dd9ed3... checks/reviews after any head movement. Current five repository-owned runs on 86dd9ed3... are still queued and there is no qualifying exact-current independent approval. This is a prerequisite-restack finding, not a request for a no-op wake, manual rerun, force rewrite, or gate weakening.

[seonghobae]

Current-base reconciliation is incomplete at exact 6be76f6594b784d93d7be33fa1677b2419bf07b2: tests/test_opencode_agent_contract.py still restores the obsolete coverage-source-tree assertions even though protected main@4e56ff0fd10e8d56e9af273881a7eb65d7e4f513 already folded that job into validate-pr-metadata, and this PR does not modify .github/workflows/opencode-review-dispatch.yml. On the current branch tree the test therefore expects a job that is absent from the inherited workflow. This is a current-generation test/owner-contract defect, not queue noise. Repair should adopt the protected-main test file unchanged; no CodeQL/bootstrap behavior needs to change.
