ci(security): materialize stacked-PR validation on trusted branch

[seonghobae]

Current exact-head repair — 2026-09-07

• Exact head: 59a8f4eadfe0e0dcc5ff47cf1acfb80403e241ad.
• Commit 59a8f4e… extends the stacked-workflow contract so all three trusted jobs must retain both Ready-only admission and the closed-PR exclusion.
• All predecessor check/review results are stale for merge admission. Fresh exact-head source, security, Noema, OpenCode, Strix, compatibility CodeQL, and coverage evidence must complete before ordinary merge.

목적

Fork PR #1060의 유효 delta를 base 저장소 trusted branch에 완전 승계합니다. repository-local Security and Quality workflow가 stacked PR에서도 실제로 materialize되도록 pull_request base filter를 제거하고, push는 main에만 한정합니다. 회귀 계약은 그 trigger 경계를 직접 고정합니다.

선행 RED와 foundation 해소

이전 exact head 51c8824e219c887425d2e7147e87f088d5f1a77d의 Security and Quality run 33923471573은 실제 GitHub-hosted runner에서 workflow 자체를 정상 실행했습니다. CodeQL, supply chain, and SBOM과 fuzz job은 통과했지만 Tests and package quality는 5 failed, 3390 passed, 2 skipped로 실패했습니다. 원인은 이 두 파일의 CI delta가 아니라 protected main의 NVIDIA hosted-access evidence가 2026-09-04 뒤 fail closed한 것이었습니다.

그 foundation은 별도 PR #1073에서 공식 NVIDIA NIM General FAQ를 2026-09-05 재검토하고 evidence horizon을 갱신한 뒤 정상 병합됐습니다. 현재 protected main은 merge commit a080297d2546bb61e89520d637cabc202db331ec입니다. 따라서 과거 body가 가리키던 미병합 #1069는 더 이상 prerequisite authority가 아닙니다.

Non-force descendant restack

Fresh live comparison에서 #1066의 effective product delta는 .github/workflows/security.yml과 tests/test_repository_security_metadata.py 두 파일뿐이고 #1073의 five-file NIM evidence/test delta와 겹치지 않았습니다.

Normal two-parent descendant dc1cae91655ef5ae0953f0e247fcd58da2b3fcff는 이전 branch head 51c8824...를 first parent, current protected main@a080297d...를 second parent로 보존합니다. Tree는 current protected-main tree 위에 이 PR의 두 validated blobs만 overlay해 만들었고 branch ref는 force=false로 전진했습니다.

Fresh compare는 protected main을 exact merge base로 가지며 ahead_by=3, behind_by=0; effective diff는 다시 두 파일뿐입니다. NIM evidence, benchmark source/docs/tests, protected-main history를 복제하거나 되돌리지 않았습니다.

Promotion boundary

이제 prerequisite source RED는 해소됐지만 predecessor checks는 새 head로 이전하지 않습니다. 이 unchanged exact head에서 full suite, coverage/docstring contract, fuzz, CodeQL/supply-chain/SBOM, central security/SAST/review contexts가 새로 terminal-valid해야 합니다. 독립 current-head approval과 live branch/ruleset 재조회 뒤에만 정상 protected merge를 검토합니다.

No self-approval, admin bypass, gate weakening, force push, destructive rebase, source-neutral retrigger, or predecessor-evidence transfer. #1060은 이 trusted successor가 protected main에 도달하고 complete semantic/test equivalence가 확인될 때까지 lineage로 유지합니다.

Keep — this PR carries a delta no other open PR contains.

A cross-session triage note proposed retiring both this and #1060 in favour of #1072. That is correct for #1060 but not for this PR, and acting on it would drop real work. Verified by diffing all three against their own merge bases:

• fix(actions): pin security.yml jobs off starved floating ubuntu-latest #1072 is orthogonal, not a successor. Its entire security.yml change is runs-on: ubuntu-latest → ubuntu-24.04 on three jobs, plus the matching runs-on count assertion. It contains none of this PR's trigger, draft/closed, or concurrency work.
• This PR supersedes ci(security): run checks on stacked pull requests #1060, containing its test_security_workflow_supports_stacked_pull_requests byte-identical plus the guards ci(security): run checks on stacked pull requests #1060 lacks.

Unique to this PR:

• explicit types: [opened, synchronize, reopened, ready_for_review, converted_to_draft, closed]
• github.event.pull_request.draft == false on all three jobs (asserted via count(...) == 3)
• concurrency: cancel-in-progress scoped to pull_request events only, and run_id rather than ref as the non-PR fallback

Merge-order suggestion: #1072 first (it is currently MERGEABLE, is the smallest diff, and directly targets the runner starvation behind the queue backlog), then rebase this one onto it. The two touch security.yml and tests/test_repository_security_metadata.py in disjoint places, so the rebase should be mechanical — but whichever lands second must re-run the suite, since both edit the same test file.

Adjudication evidence (host 1 session, 2026-09-06 KST; full report with commands in #1080). Nothing here closes, flips, or retargets anything — the decision is the opener's.

Stack root for #1068 (codex/stacked-security-successor is this head) and, through it, #911 / #1032 / #1034 / #1046 — nothing above may merge before this. It also contains #1060's change (identical patch-id first commit).

Findings: two changes in one PR (base-filter removal + new draft/closed/concurrency policy) with no CHANGELOG although CI trigger and concurrency semantics change; the closed trigger yields a run in which every job is skipped — if any of the three job names is a required context, drafts and close events will show it skipped; opencode/noema/strix are all failure on dc1cae91. Merge-tree vs #1072: three adjacent security.yml hunks (keep your if: >- blocks and #1072's runs-on: ubuntu-24.04 at all three jobs; afterwards count('runs-on: ubuntu-24.04') == 3, count('pull_request.draft == false') == 3).

Consumer evidence and existing-writer coordination (2026-09-06)

The psychometric child #1074 at fa8eef97cd7368e8985a367dc5a7a8e0147fe4d5 is Draft, based on codex/psychometric-kpi-successor. Its exact-head Actions and check-runs endpoints returned zero runs/check-runs. Parent #1067 at d740602fdd8c0e4f7d55e4d3ad37b9f560c09e01 had nine queued/pending runs; the two successful status contexts explicitly skipped their reviews. This is a trigger/admission observation, not a request to treat Draft skips as completed validation or to convert either PR to ready.

This PR remains the existing stacked-trigger repair at dc1cae91655ef5ae0953f0e247fcd58da2b3fcff; #1072 and issue #1080 already carry related integration findings. Could the existing writer identify the owning task or next exact-head validation checkpoint here? Please retain this consumer case in the protected integration test. I own only #1067/#1074 and have not changed this branch, rerun its jobs, or altered reviews. No replacement writer, duplicate workflow, gate bypass, or precursor closure is proposed.

Exact-head failure triage (59a8f4e): the Python CodeQL compatibility job 101608688300 in run 34073908462 ended with DISPATCH_OUTCOME=success and VERDICT_STATE=pending. It is not evidence of a passing scan or of a source vulnerability; its dispatched terminal verdict must be located before any repair/rerun decision.

Noema job 101609961568 in run 34073907313 reported gateway HTTP 502 after 1806.8 seconds, one caller attempt, response_error phase. Matching sidecar artifact: 10005074171, SHA256 680e91ce448200851ed0c2b76efed21206c88c29da98fe3b340994dddd621b9f. Do not convert this transport failure to a code-review approval or impose a new blanket model timeout.

PR #1108 demonstrates the remaining stacked-consumer gap: ready-for-review, but zero Actions runs and CodeRabbit explicitly excludes its base branch. #1066 is the existing trusted successor of #1060; no duplicate workflow patch has been added. Protected delivery and independent exact-head review remain pending.

[seonghobae]

Resolved the previously pending Python dispatch receipt: central run https://github.com/ContextualWisdomLab/.github/actions/runs/34082855181 targets #106659a8f4e. validate-dispatch passed; Python job 101636669590 failed specifically at Publish CodeQL dispatch status. Its log records HTTP 403 Resource not accessible by integration for both target-app-token and github-token, then deliberately leaves the required job failed without waking it with stale/missing evidence.

This is a verified result-publication authorization failure, not an indefinitely running scan. It does not establish absence of secrets, nor does it justify setting a manual success status. Fix the canonical publisher authorization, then revalidate exact-head evidence; repeating the consumer compatibility job alone will not repair this condition. Other language shards and SARIF findings remain separately unverified.

[seonghobae]

Current authorization recheck on 2026-09-09: installation 141441800 for opencode-agent has statuses=read, checks=read, actions=read. The public app registration also declares statuses=read and is owned by anomalyco. This directly explains why the target installation token cannot publish commit statuses; requesting broader token permissions cannot exceed the registered app permissions. Existing central PR #1991 only adds diagnostics for empty credential rungs and explicitly does not fix authorization. Do not treat it as a permission repair or infer missing secrets from a permission denial. Updating this external app registration requires its owner; selecting a different authorized canonical publisher remains a separate security-reviewed change.

[seonghobae]

Lineage reconciliation: the research branch now normally merges your full head 59a8f4e at d721e04, preserving Ready/closed admission, PR-only cancellation, and all existing metadata contracts. A partial duplicate trigger change had missed this existing owner; its duplicate test file was removed after consolidating extra branches-ignore/path-filter/event-permission assertions into your canonical metadata test. The workflow blob is identical to your head. Metadata + NIM workflow contracts: 21 passed in 4.45 seconds; actionlint clean. This is branch integration, not protected delivery or approval. #1066 and #1060 remain open with their valid lineage preserved.
