Security/runtime defect

Protected develop still runs the complete Accounting Foundation suite against postgres:18.4, while PostgreSQL 18.6 has been the current supported PostgreSQL 18 minor since 2026-08-13. PostgreSQL's release notice says 18.6 fixes 28 security vulnerabilities and more than 110 bugs; 18.5 was not shipped because of a regression. Keeping 18.4 as the claimed current runtime baseline makes security and compatibility evidence stale.

This PR changes test/runtime evidence only. It does not change journal, posting, reversal, period-close, reconciliation, reporting, Billing ACL, or accounting-policy truth.

TDD / repair lineage

  • RED 80dce77e117d6a20948b083758c4221005b71fde adds tests/test_postgresql_runtime_baseline.py, requiring the exact pinned PostgreSQL 18.6 image and rejecting postgres:18.4 in Accounting Foundation CI. On parent develop@239008c4edc7d305c97704c5102b593c6622b36f, that contract is necessarily unsatisfied because CI is still pinned to 18.4; no observed runner RED is claimed for that predecessor.
  • GREEN candidate 71ad985c71db745938c9e66e060a982621636236 changes only the service image from postgres:18.4@sha256:a02db8... to official postgres:18.6@sha256:4ef4dbc939d61acea57712655ddb4b4ab27419c913f94cca0cd57cb3ea3c2280.
  • Documentation candidate b2a7196549f76eee1e3f51bf1ef196facebaab15 records release date, security rationale, immutable OCI digest, historical-evidence rule, and exact-head CI acceptance.
  • Operational-evidence RED 45c13ce5741e65d096cab4899ac3bd7c0d55c70d strengthens the repository contract so an ephemeral image bump cannot stand in for an existing-cluster upgrade. It requires the runtime baseline to retain the PostgreSQL 18.6 operator checks for output_plugin_libraries, pgcrypto, failing COPY ... FROM STDIN scripts, GIN/reltuples, btree_gist, ltree, and exact post-upgrade server identity. The predecessor documentation did not contain those acceptance facts; no runner-executed RED is claimed because the successor repair was committed without waiting on the queue.
  • Minimal documentation repair cf3c4d8eb70bc0e36fa08c58e448cf354dde604e separates clean CI-image evidence from existing-cluster upgrade evidence. It requires live-cluster preflight/applicability proof, preserves the PostgreSQL 18.6 release-note remediation paths, and states that runtime recovery cannot authorize rewriting posted, reconciliation, or close history.
  • Review repair aaa07974595cef0e68f70cebe74d5a92d1dd1ea3 binds the regression to the direct services.postgres.image field, the ## Current baseline version/digest, and the separate existing-cluster section. Mutation evidence changed the real field/current section to 18.4 while leaving unrelated 18.6 text; both tests failed, then passed after restoration.

Evidence and acceptance

Primary release authority is the PostgreSQL Global Development Group's 2026-08-13 PostgreSQL 18.6 announcement and 18.6 release notes. Image identity remains the official postgres:18.6 multi-platform index digest sha256:4ef4dbc939d61acea57712655ddb4b4ab27419c913f94cca0cd57cb3ea3c2280.

The version bump is not GREEN merely because the image exists. Exact-head Accounting Foundation must execute the complete behavior suite and real PostgreSQL regressions, 100% production statement/branch coverage, repository contracts, packaging, SBOM and reproducibility against 18.6. Existing-cluster release evidence must additionally prove the release-note preflight against the live target cluster rather than inferring absence from repository source or an ephemeral CI database.

Historical ADR/test statements that say a specific past run used 18.4 remain valid historical evidence. Current-baseline claims of 18.4 are superseded and should be corrected in their canonical documentation lanes rather than falsifying past run provenance.

Exact current state — 2026-09-09

  • exact head: aaa07974595cef0e68f70cebe74d5a92d1dd1ea3;
  • exact protected base: develop@239008c4edc7d305c97704c5102b593c6622b36f;
  • state: open / Ready for review / mergeable / not merge-ready;
  • exact-head Accounting Foundation CI 34083267792 is terminal GREEN: 462 behavior/repository tests passed twice, coverage proved 4,981/4,981 statements and 1,796/1,796 branches, repository/contracts/compile/import/build/reproducible wheel/typing marker/package/SBOM/provenance stages succeeded, and its exact-head dependency/SAST/security jobs succeeded;
  • standalone Security Scan 34083267855 and SAST Semgrep 34083267756 are terminal GREEN. Required CodeQL PR 34083267746 is historical terminal RED, so this exact AIP head has not satisfied the current central CodeQL gate;
  • protected central workflow authority is now .github/main@7fd571dbcdbae6acf29d8f4ee704d7ba6297e4db after ordinary integration of #2028, not the older 78a4937... generation;
  • the current canonical combined central repair is .github#2040@6706c231ab06a3c91c43fdb5b989cfcd79fff593, Ready/mergeable on protected main@7fd571.... Its exact-head Security 34251822390, SAST 34251822314, Python Security 34251822251, and Runtime Quality 34251822381 are terminal GREEN; CodeQL 34251822255 is terminal RED. The central owner is still repairing current-generation exact failed-job/receipt settlement and provenance compatibility. This leaf must wait for ordinary central integration plus a genuinely fresh required-workflow generation rather than replaying historical AIP CodeQL;
  • .github#2040 carries the valid combined producer/handler/recovery lineage and explicitly rejects head-only compatibility. AIP must not copy mutable central workflow bytes or weaken exact repository/PR/base/head/language/required-run/SARIF identity to make this runtime-baseline PR pass;
  • no AIP-local PAT/status workaround, synthetic status, no-op push, Draft/Ready churn, actor/sender weakening, or historical required-workflow rerun is an accepted recovery path;
  • the exact-head CodeRabbit test-contract finding is repaired and its thread resolved; no qualifying independent current-head APPROVED review is present.

Review admission / merge / release boundary

Ready admits current-head review; it is not merge, approval, release, or hosted-GREEN evidence. Keep this exact head unmerged until the central owner plane integrates a passing current-generation CodeQL producer/settlement path, this unchanged or correctly descendant AIP head obtains fresh authenticated terminal CodeQL evidence under that protected producer, every other live required workflow is terminal GREEN, and qualifying independent review is present. Existing-cluster PostgreSQL 18.6 upgrade/recovery evidence remains a release-readiness requirement distinct from ephemeral CI-image proof.

Do not merge, auto-merge, bypass protection, self-approve, force-push, destructively rebase, tag, version, or release while any applicable evidence is absent, failed, queued, cancelled, stale, predecessor-only, or synthetic.

CI 서비스 이미지를 postgres:18.6과 지정된 불변 다이제스트로 변경했습니다. 기존 postgres:18.4 이미지가 없는지와 문서의 업그레이드 증거 항목을 테스트합니다. SBOM 경로 입력은 변경하지 않았습니다.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to cf3c4

This updates the CI PostgreSQL service to the pinned 18.6 image and documents cluster-upgrade requirements. The active behavior appears aligned with the new baseline, but the new contract tests should validate the specific service and current-baseline sections before merge to reliably prevent baseline drift.

Fresh cross-lane finding from Period Close #53: its currently changed docs/doctoring/STANDARD_TRACEABILITY.md still contains present-tense rows labelled PostgreSQL 18.4 / PostgreSQL 18.4 test environment, including a claim to use the current supported minor. Those statements are not historical run provenance; they are current-baseline claims and will be stale once this runtime owner lane integrates 18.6. Keep #55 as the canonical runtime-baseline owner. Do not duplicate its image/digest/upgrade controls into #53; after #55 reaches protected develop, the stacked reconciliation/Period Close chain should non-force restack from that protected descendant and the canonical documentation lane should update only present-tense 18.4 claims while preserving historical 18.4 execution evidence.

Fresh exact-head evidence update for cf3c4d8eb70bc0e36fa08c58e448cf354dde604e: Accounting Foundation 33921491517, Security Scan 33921491717, and SAST Semgrep 33921491668 have now completed success. The PR remains Draft because CodeQL PR 33921491711 is terminal failure: both actions and python shards successfully requested current-head dispatch, then failed at the fail-closed terminal-verdict step because a trusted terminal CodeQL verdict was not yet available.

Do not add a leaf workaround. The canonical owner repair .github#1902 has just been non-force restacked onto protected .github/main@d9eb9f79b6ce66c1225c26be385ae814d87d9aca; its new exact head is 2d4624a3998baf79944d2a76b2a3367946b0d923, ahead 9 / behind 0 with the same four-file CodeQL recovery delta, and its new exact-head security/SAST/CodeQL/Python-security runs are queued. Re-evaluate #55 only after that owner path integrates and this unchanged consumer head gets an authenticated terminal CodeQL verdict. Existing-cluster PostgreSQL 18.6 upgrade/recovery evidence and independent approval also remain separate merge gates.

Review exact unchanged head cf3c4d8eb70bc0e36fa08c58e448cf354dde604e. Ready was restored only to admit current-head review; it is not merge/approval/release evidence. Accounting Foundation 33921491517, Security Scan 33921491717, and SAST Semgrep 33921491668 are terminal success. CodeQL PR 33921491711 remains terminal failure in the central authenticated-verdict path; canonical owner .github#1902@4b025af481f3a4fb0bdb4d400a7e055066a496a2 is still queued and is a merge gate, not a Ready prerequisite. Do not add a leaf workaround, synthetic status, empty rerun commit, allowlist widening, force-push, self-approval, bypass, merge, or release. Validate the three-file PostgreSQL 18.6 runtime/security-baseline delta against this exact head and report only concrete current-source findings.

Re-review exact head aaa07974595cef0e68f70cebe74d5a92d1dd1ea3. The CodeRabbit field/section-binding finding is repaired and its thread is resolved. Mutation evidence: with the actual services.postgres.image changed to 18.4 while the expected 18.6 value remained only in a comment, and the ## Current baseline section changed to 18.4 while later 18.6 text remained, the strengthened suite failed exactly 2 tests; after restoration it passed 2/2, repository contracts were valid, and git diff --check was clean. Fresh hosted runs are non-terminal. Review only this exact one-file test-contract delta; do not transfer predecessor evidence, add a leaf CodeQL workaround, force-push, self-approve, bypass, merge, or release.

Current exact-head gate correction for aaa07974595cef0e68f70cebe74d5a92d1dd1ea3 (2026-09-07): the PR body's older sentence saying external Security/SAST/CodeQL are queued is stale. Fresh Actions inventory shows Security Scan 34083267855 success, SAST Semgrep 34083267756 success, and required CodeQL PR 34083267746 failure. Required PR Review Merge Scheduler 34083266382 is success, Required Noema Review 34083266294 is failure, Required OpenCode Review 34083266423 remains queued, and Strix 34083266474 is in progress. The separate dynamic Code Quality: PR #55 run 34083265257 succeeded but does not replace the required CodeQL PR gate. Keep Ready/not-merge-ready; no predecessor or dynamic-code-quality evidence authorizes merge.

Central-owner refresh — 2026-09-09. The body’s .github/main@78a4937... / #1902 section is now historical. Protected central main is 7fd571dbcdbae6acf29d8f4ee704d7ba6297e4db (merged #2028). The current combined CodeQL repair is .github#2040@6706c231ab06a3c91c43fdb5b989cfcd79fff593, Ready/Proposed. Its Security, SAST, Python Security and Runtime Quality runs are terminal GREEN, but CodeQL PR 34251822255 is terminal RED: both compatibility jobs fail current-head verdict admission and coordinator job 102154736341 ends with CodeQL coordinator could not bind every pending language to an exact failed job.

That remains a canonical central owner-path defect, not a reason to mutate this PostgreSQL 18.6 leaf. Do not rerun the old #55 CodeQL generation, publish synthetic status, add a PAT workaround, no-op push, or weaken required checks. Preserve aaa07974595cef0e68f70cebe74d5a92d1dd1ea3 and its already-GREEN PostgreSQL 18.6 Foundation evidence until the central repair produces a fresh compatible generation; then reacquire CodeQL on this unchanged head if still current.
