fix(codeql): bootstrap versioned dispatch handler

[seonghobae]

Current canonical state — 2026-09-17

This PR remains the sole open canonical landing vehicle for the versioned CodeQL dispatch handler. Protected .github/main is 89b225dbecc1c71e3f876fa9d376080093af37e4; current exact head is fdab6730d72dacbe375f466f7434cf085bd4cd2f, Open / Draft / mergeable. The branch remains an ordinary descendant of the current protected base and has not been force-pushed or destructively rebased.

The current branch-only diff remains nine files: the CodeQL handler, CHANGELOG, ADR/doctoring/baseline records, three existing contract-test files, and the focused repository-identity regression contract originally added at 84297876....

Handler contract

• One codeql-scan-dispatch.yml accepts legacy codeql-scan and staged codeql-scan-v2 events.
• Legacy title/payload/status contracts remain intact while v2 binds producer source, ordered merge parents, nested PR-head provenance, and string schema "1" for nested-rerun authority.
• Matrix shards remain read-only consumers. On attempt 1 they read an authenticated codeql-dispatch/<language> verdict or a completed matching dispatch job; when neither exists they emit verdict=pending and intentionally fail to release the runner. One downstream dispatch-current-head coordinator, after the shard matrix has settled, POSTs the remaining language matrix to codeql-scan-dispatch.yml; the handler publishes terminal verdicts and reruns only the exact failed jobs.
• Required-run attempt 48 stops before mutation; failed credential stdout is discarded so later successful fallback evidence cannot be contaminated.
• v1 and v2 share one concurrency owner. v1 is removed only after protected v2 producer integration, all v1 attempts terminal, and caller inventory reaches zero.

Current RED: owner-qualified durable evidence identity

docs/product-technical-gap-baseline.md still contains two cross-repository evidence identities without an owner namespace: contextual-orchestrator#1149@684cf28f and fast-mlsirm@09f762d. Their durable forms are ContextualWisdomLab/contextual-orchestrator#1149@684cf28f and ContextualWisdomLab/fast-mlsirm@09f762d. The baseline blob is again exactly 43027eef506ed136bc394981f7f342e364c068ca.

Commit 84297876..., retained in the ancestry of current fdab673..., adds tests/test_product_technical_gap_baseline_repository_identity_contract.py. The contract rejects the two exact backtick-delimited legacy identities and requires both owner-qualified forms. It is intentionally RED against the current baseline and therefore cannot be counted as GREEN evidence. The previous temporary rehearsal from a5569a... remains superseded/reverted and is not reused.

An attempted Contents-API source repair at 5e4dfe4bf63747159df70adec8a6d6d1b81abee9 was rejected after immediate exact parent/head comparison showed 35 textual changes in the hot baseline instead of the intended two-token delta. Non-force descendant fdab6730d72dacbe375f466f7434cf085bd4cd2f restores the prior baseline blob byte-for-byte; compare from pre-attempt head ff72f8b... to current fdab673... is 2 commits ahead / 0 behind with zero net file changes. No evidence from the rejected intermediate generation transfers.

The remaining causal source repair is deliberately only the two documentation identities. The large hot baseline must not be opportunistically reserialized or rewritten to make the test pass; after an exact two-token source correction, that resulting exact-head generation must reacquire its own hosted checks and independent current-head review.

Exact-head acceptance boundary

Current fdab673... workflows are newly materialized and nonterminal: Agent Review Runtime Quality CI 35145861624, SAST Semgrep 35145861559, Python Security 35145861477, and Security Scan 35145861463 are queued; CodeQL PR 35145861525 is pending. None is terminal evidence yet, and no no-op wake, cancellation, blind rerun, or predecessor result substitutes for them.

#2106 remains Draft until all obligations are satisfied on one final exact head: the two owner-qualified documentation identities, the executable regression contract GREEN against that same source, authenticated terminal CodeQL settlement after the security-gate repair, required security/quality checks, and qualifying independent current-head review. Coordinator success by itself, synthetic status, self-approval, administrator bypass, force push, destructive rebase, gate weakening, or mutable dependency substitution is not merge authority.

#2040 remains the downstream versioned producer/consumer cutover and must not be restacked or landed ahead of this bootstrap; after #2106 normally reaches protected main, #2040 must ordinary/non-force reconcile onto that protected tip and reacquire its own exact-head/current-base canary evidence.

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.

[seonghobae]

Fresh owner-path verification confirms #2106 remains the canonical landing writer for the Python CodeQL finding now also reproduced by #2170 producer 34921233636. The current source repair at 298e6c14c9a56b51c61df2d2e35d7545f0f4f288 matches the failing rule/location and should not be duplicated downstream.

The remaining byte-local documentation defect is also still present on this exact head in docs/product-technical-gap-baseline.md under CONTROL-OPENCODE-VCS-PYROOT-01:

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

Current blob SHA for that file is 43027eef506ed136bc394981f7f342e364c068ca (327,074 bytes). The available contents-write primitive is whole-file replacement, so I did not risk reserializing a 327 KB hot baseline merely to change two identities. This is a tooling-safe-write limitation, not a reason to declare the finding complete: #2106 should remain Draft until those two exact replacements are made by a byte-preserving owner write and the FINAL exact head obtains authenticated terminal CodeQL plus the other required checks. No suppression, no no-op wake, no downstream #2170/#2040 restack before that.

[seonghobae]

Downstream consumer evidence from ContextualWisdomLab/naruon confirms this bootstrap/cutover remains an owner-path prerequisite rather than a leaf-workflow repair:

• naruon#1623@ecbeb7a191b981d3e46eb8455e11812ca21de482 has terminal GREEN Application CI and full dependency Security Scan (trivy-fs, osv-scan, dependency-review, scorecard), yet the central CodeQL compatibility jobs for actions/javascript-typescript/python are not GREEN on that exact head.
• naruon#1694@10f046ee5ea004ec9236d59d3ccfeab3e1a417be independently shows the same central compatibility problem class: required actions and javascript-typescript compatibility jobs are terminal FAILURE while GitHub Advanced Security's separate native CodeQL check reports no new alert in the PR diff; python remains nonterminal in the latest inventory.
• docs: add reusable README template and evidence standard #1694 also has a separate repo-wide Trivy failure which disappears on the canonical dependency-security owner test(review): lock split target and central mention authority #1623, so that finding is being kept in the Naruon dependency owner path rather than mixed into this central CodeQL repair.

No Naruon central-workflow copy, synthetic status, bypass, or no-op retrigger is being introduced. Naruon will keep the affected PRs Draft and wait for the protected .github owner sequence #2106 -> #2040 (or verified complete successors) to land normally, then reacquire exact-head/current-base compatibility evidence.

[seonghobae]

Fresh protected-base movement creates a new reconciliation obligation before this PR can claim final exact-head/current-base acceptance.

.github/main has advanced from 91be6442906c7b6b4f600272c953699708394327 to protected e0d022e5ff0cc061fa6bd542edb4837a2f67c0ea via merged #2221 (docs: CI queue-stall baseline (24h) + scoping ADR). Independent compare from current protected main to #2106 exact cf7fa8635e6422db35fa60b9580cb3803cd42c1a is now diverged: 35 ahead / 2 behind, merge base exactly the old 91be644.... Treat this as a wrong/current-base repair finding, not as a reason to discard the CodeQL delta: reconcile ordinarily/non-force onto current protected main and then reacquire the complete exact-head/current-base evidence; do not transfer the currently queued generation.

The new protected #2221 material is also relevant to the current queue diagnosis. It records an org-wide 24h baseline and scoping ADR showing the observed single-digit in_progress versus hundreds queued pattern is consistent with the plan-level concurrent-job ceiling, not missing workflow-level concurrency: blocks; the applicable event-triggered required workflows were checked and already have the low-risk concurrency/cancel-in-progress control where appropriate. #2106 exact-head runs (35094270714, 35094270842, 35094270780, 35094270704, 35094270692) are still queued, so do not turn this base movement into a wake/no-op commit or blind rerun. Reconcile ancestry first through the canonical owner lane, preserve the byte-local owner-identity documentation repair, then let one final generation settle.

[seonghobae]

Fresh downstream owner-path evidence for the versioned CodeQL bootstrap, without mutating this dedicated-writer branch.

ContextualWisdomLab/linux-cluster-ops#306@6ca30fc6ef2c3c02f11fa752a783d1c353a7ee1f has a deterministic producer-side transport RED in required CodeQL run 34683056632, dispatch job 103525928667. The job successfully validates the live PR/head/base and the actions+python matrix, successfully obtains GitHub OIDC, and successfully exchanges that OIDC credential for a repository-scoped App token. The final mutation then fails at exactly:

GH_TOKEN="$app_token" gh api -X POST repos/ContextualWisdomLab/.github/dispatches --input -

with HTTP 403: Resource not accessible by integration.

This is not a leaf SARIF/source finding and should not be repaired by a no-op leaf commit, blind rerun, PAT fallback, or permission broadening in linux-cluster-ops. It is concrete evidence that the protected producer credential/installation authority currently cannot perform the central repository_dispatch mutation after successful OIDC/App-token exchange.

Owner RED acceptance: preserve a contract/canary in the canonical CodeQL owner that distinguishes successful OIDC + App-token exchange from authorization to POST repository_dispatch to ContextualWisdomLab/.github; the denied credential must fail closed before any synthetic verdict/status can authorize the leaf.

Owner GREEN acceptance: through the least-privilege canonical App/installation path, one unchanged leaf identity {target=ContextualWisdomLab/linux-cluster-ops, pr=306, head=6ca30fc6ef2c3c02f11fa752a783d1c353a7ee1f, base_ref=develop, base_sha=7d6c0e6f488dffb609eded3f8980ded570b54362, required_run=34683056632, languages=[actions,python]} must be able to create exactly one authenticated central dispatch; the protected handler must bind that identity, publish terminal language verdicts, and the original required CodeQL workflow—not a synthetic substitute—must terminate from those verdicts.

Because repository_dispatch executes the protected default-branch handler, this is post-protected-integration acceptance for the versioned handler/producer sequence. Do not infer GREEN from this PR's branch-only handler or from a coordinator that merely reaches its POST step. #2106's current documentation RED and exact-head checks remain independent obligations.

[seonghobae]

Exact-head repair note for the owner-qualified baseline finding: an attempted Contents-API edit produced commit 5e4dfe4bf63747159df70adec8a6d6d1b81abee9, but immediate parent/head comparison showed 35 textual changes in docs/product-technical-gap-baseline.md, not the intended two-token delta. That generation was rejected before being treated as repair evidence.

The branch was repaired without force-push or history rewrite: descendant fdab6730d72dacbe375f466f7434cf085bd4cd2f restores the baseline byte-for-byte to prior blob 43027eef506ed136bc394981f7f342e364c068ca. Fresh compare from pre-attempt head ff72f8b936ce773b11133b09d9f423469b346ade to fdab673... is 2 commits ahead / 0 behind with 0 net file changes. The intentional repository-identity RED therefore remains exactly intact; neither the bad intermediate blob nor any checks attached to it are acceptance evidence.

The next source mutation must be an exact two-token repair only. I will not reserialize the large hot baseline through a write surface that cannot prove byte-preservation outside those two identities.
