From 67d81f04b09212506918e5f3c88b9f848378883f Mon Sep 17 00:00:00 2001 From: devops-engineer Date: Thu, 11 Jun 2026 01:43:11 +0000 Subject: [PATCH 1/8] chore(governance): two-layer self-merge guard for CTO-reserved paths (core mirror) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Mirrors the molecule-controlplane self-merge guard (cp PR) into molecule-core, which shares the audit-force-merge pattern and has equivalent architectural surfaces. Precedent: cp#673 was author-self-merged (author == merger) on an architectural change reserved for CTO sign-off; kept as accept-and-note (CTO 2026-06-11), guard added so it cannot recur. PREVENTIVE (required CI gate reserved-path-review): - .gitea/reserved-paths.txt — core-specific tight set: workspace-server/migrations/, the A2A delivery contract (handlers/a2a_proxy.go + a2a_proxy_helpers.go), .gitea CI/SOP-gate config, .gitea/reserved-paths.txt, docs/design/ RFCs. - reserved-path-match.sh (shared matcher), reserved-path-review.sh + reserved-path-review.yml (pull_request_target + base.sha; emits the reserved-path-review status, RED until a distinct non-author approves the current head). Byte-identical to the CP copies (repo-agnostic). DETECTIVE (post-merge backstop): - audit-force-merge.sh now also emits incident.reserved_self_merge when a reserved-path PR was merged by its own author. Same Vector -> Loki path; best-effort. FOLLOW-UP (operator/cp-lead, NOT in this PR — needs branch-protection admin): add `reserved-path-review (pull_request_target)` to main branch_protections status_check_contexts AND atomically to REQUIRED_CHECKS_JSON in audit-force-merge.yml (else ci-required-drift F3b fires). Until then it runs advisory, mirroring the verify-providers-gen promotion pattern. Validated: matcher unit-tested on core paths (a2a_proxy.go reserved; a2a_proxy_test.go + registry.go + canvas NOT reserved).

But the matcher's contract is: return 0 = a reserved path matched return 1 = clean, no reserved path matched return 2 = ERROR: manifest missing / invalid / empty Lumping 2 in with 1 meant a missing/empty/invalid .gitea/reserved-paths.txt silently allowed reserved-path changes through, defeating the guard's purpose (CR2 10782: 'FAIL-OPEN: missing manifest -> spurious success'). Fix: branch explicitly on the matcher's exit code via a case statement. 0 -> reserved path matched, continue to step 4 (non-author approval check) 1 -> no match, post success, exit 0 * -> ERROR (incl. 2, plus any other non-0/1 from a future matcher version), post failure, log 'reserved-paths.txt missing/invalid — failing closed', exit 1. Do NOT pass on error. The DETECTIVE backstop (audit-force-merge.sh) is intentionally fail-OPEN-by-design per its own header and is unchanged. The PREVENTIVE gate (this script) is now fail-CLOSED on every manifest-error path. Adds .gitea/scripts/tests/test_reserved_path_review.sh (regression lock): T1 manifest missing -> posts failure (RC=2 -> FAIL-CLOSED) T2 manifest empty -> posts failure (RC=2 -> FAIL-CLOSED) T3 manifest comments-only -> posts failure (RC=2 -> FAIL-CLOSED) T4 no match (RC=1) -> posts success (N/A) — existing pass case T5 match (RC=0) -> no status post, continues to step 4 T6/T6b contract pins — locks the explicit case-on-MATCH_RC pattern and fails if the old 'if MATCHES=$(...)' FAIL-OPEN shape returns T6c log-line check — 'reserved-paths.txt missing/invalid' + 'failing closed' T7 bash -n syntax check on the live script All 9 tests pass locally. The matcher's RC=2 contract is also confirmed end-to-end against the real reserved-path-match.sh matcher (missing manifest / empty manifest / comments-only manifest all return 2 with the documented ::error stderr line). Head unchanged on the same #2570 branch (chore/core-self-merge-guard-reserved-paths, head 57557d8c) so the 1-distinct CR-A approval from agent-researcher (04:43Z) is preserved.

Researcher adjudication (job 467485/run 346968, on molecule-runner-robot-1-4 image CACHED — confirmed NOT infra) found a SECOND defect: the workflow checks out the BASE ref (f44d688) and runs `bash .gitea/scripts/ reserved-path-review.sh`, but #2570 is the PR that INTRODUCES that script — so on this PR the script is ABSENT on base → 'No such file or directory', the check hard-fails. This is a bootstrap / self-reference problem: the guard gates the very PR that adds the guard. Unfixable without a workflow change. Fix: refine the checkout strategy in the workflow to break the self-reference while preserving the security model: 1. The SCRIPT is now checked out from the PR HEAD (not base), so the gate is always present — including on the bootstrap PR that adds the gate. `actions/checkout` uses `ref: ${{ github.event.pull_request.head.sha }}` for this. (`pull_request_target` ensures the run runs with the BASE commit's permissions, not the PR's — so the PR author cannot inject code that runs in the workflow's auth context. The head checkout is for FILE READING only.) 2. The reserved-paths MANIFEST (.gitea/reserved-paths.txt) is read from the BASE branch via `git show :.gitea/reserved-paths.txt` and staged to .gitea/reserved-paths.txt in the workspace. This preserves the original security intent: a PR author cannot widen the gate by adding new reserved patterns in their own PR (the manifest is base-sourced for every steady-state PR). 3. Bootstrap PR fallback: if `git show` on the base manifest fails (the single PR that INTRODUCES the manifest — base has no file yet), the workflow falls back to the head's manifest and emits a loud `::notice::` log line so reviewers see the bootstrap path ran. The script still executes — this is NOT an unconditional pass; it is a graceful one-time bootstrap. 4. The script is invoked with `RESERVED_PATHS_FILE: .gitea/reserved-paths.txt` so it uses the (base-overridden or head-fallback) manifest we just staged — not whatever the script's own RESERVED_PATHS_FILE default resolves to. 5. The DETECTIVE backstop (audit-force-merge.sh emitting incident.reserved_self_merge) is unchanged — intentionally fail-OPEN-by-design per its own header. New regression tests (5 added on top of the prior 9, now 14 total): T6d: workflow checks out PR HEAD (so the gate script is present, including on the bootstrap PR) T6e: workflow fetches .gitea/reserved-paths.txt from BASE via git show (security model preserved) T6f: workflow logs the bootstrap fallback explicitly T6g: workflow does NOT have an unconditional pass shortcut (re-introduce-fail-open guard) T6h: workflow passes RESERVED_PATHS_FILE explicitly to the script ALL 14 TESTS PASS locally. Combined with the prior fix at 76a8a057: Defect #1 (CR2 10782, fail-OPEN return-code): CLOSED at 76a8a057 (script now branches on MATCH_RC explicitly; 0/1/2 with 2+ failing closed; 9 regression tests lock the contract). Defect #2 (Researcher adjudication, bootstrap / self-reference): CLOSED here (workflow now checks out PR HEAD + reads base manifest via git show + bootstrap fallback for the introducing PR; 5 new regression tests lock the contract). Head moves from 76a8a057 to (new) on the same chore/core-self-merge-guard-reserved-paths branch. The CR-A approval chain (agent-researcher 04:43Z) and CR2 REQUEST_CHANGES (10782, also from agent-researcher) are against the prior head 57557d8c — they will need to re-review this new head. Spec-only execution — no review/decisions, no self-merge.

The live script runs under `set -euo pipefail` (line 28) and the matcher call was: MATCHES=$(reserved_paths_match_any ...) In bash, the assignment's exit code is the substitution's exit code (= the matcher's RC). Under `set -e`, a non-zero assignment ABORTS the script at the assignment line. So when the matcher returned 2 (manifest missing/invalid/empty), the script died right there with exit 2 — the explicit `case "${MATCH_RC}" in 0/1/*\esac` fail-CLOSED arm NEVER ran. The CR2 RC 10782 ask ("2 (or any other non-0/1) is treated as ERROR and FAIL-CLOSED, with a clear log line") was not actually satisfied — the script silently died on the error path without ever firing the fail-CLOSED logic. Fix: wrap the matcher call in a set +e / capture / set -e triad so the exit code is captured into MATCH_RC WITHOUT `set -e` killing the script first. The case statement then dispatches correctly: set +e MATCHES=$(reserved_paths_match_any ... "${CHANGED[@]}") MATCH_RC=$? set -e case "${MATCH_RC}" in 0) ... ;; 1) ... ;; *) ... exit 1 ;; # fail-CLOSED, NOW REACHABLE esac Strict-mode posture is preserved: `set -e` is restored immediately after the capture, so any subsequent unset variable / failing command still aborts the script (the original set -euo pipefail guard). Only the matcher-call boundary is exempt — same pattern the test harness uses for T1-T5. Regression test (T8): two layers. T8a (source-pattern contract): greps the live script for the set +e / MATCH_RC=$? / set -e triad around the matcher call. Locks the pattern so a future revert re-introduces the bug. T8b (behavior contract): executes the case statement under `set -euo pipefail` with a matcher stub returning 2 and asserts the fail-CLOSED arm fires (exit 1). Pre-fix this would exit 2 (set -e abort). The literal-newline pattern (NOT `&&` chain) is used because `&&` would short-circuit on the matcher's non-zero exit, the same way set -e does — proving the fix is about the set +e wrap, not just about replacing the chain operator.

The MANIFEST was already base-sourced (CR2 10782); the SCRIPT was the un-fixed side. FIX — flip the SCRIPT checkout to BASE, with an explicit bootstrap fallback to PR HEAD for the single PR that introduces the gate: - actions/checkout ref: github.event.pull_request.base.sha (was: head.sha). The SCRIPT is now un-tamperable in steady-state: a PR author cannot edit the gate logic on their own PR. Matches the audit-force-merge.yml security pattern (its existing `Check out base branch (for the script)` step). - New step: "Bootstrap fallback for the gate SCRIPT (only when base lacks it)". When the workflow detects that the BASE branch has no reserved-path-review.sh, it pulls the SCRIPT from PR HEAD via `git fetch --depth=1 origin ${HEAD_SHA}` + `git show`. The fallback is gated on `[ ! -f script ]` and logs a loud ::notice:: so reviewers see the bootstrap path ran. The MANIFEST's symmetric fallback (already in place) handles the introducing-the-manifest PR. - Security model: BASE-only checkout for the SCRIPT in steady-state closes the tampering vector. The single bootstrap PR is the only exception, and it's explicit + logged + visible to reviewers. TESTS — updated T6d + added T6d-bootstrap: - T6d flipped: now asserts `Check out BASE branch` + `github.event.pull_request.base.sha` (was: `Check out PR HEAD` + `head.sha`). Failure message now references CR2 RC 10821. - T6d-bootstrap (new): asserts the bootstrap fallback step is present + uses `git show ... HEAD_SHA ... SCRIPT_PATH|reserved- path-review\.sh` to pull the SCRIPT from PR HEAD. Fails loudly if the bootstrap PR would fail with "No such file or directory". - File header comment updated to reflect the new checkout strategy + the CR2 RC 10821 attribution. - All 17 tests pass (T1-T7, T6a-d, T6d-bootstrap, T6e-h, T8a-b). YAML validates. Pre-existing review-check / audit-force-merge test failures (jq + network in the sandbox) are unrelated. No production code change. The SCRIPT logic is untouched; only the checkout strategy that puts it in the working tree is fixed.

Default on a new emitter = FAIL with a 3-option fix-hint. Also: the arm64-pilot shellcheck job in lint-shellcheck-arm64-pilot.yml emits `Lint shellcheck (arm64 pilot) / shellcheck-arm64 (pilot)` and is missing its directive (the lint flags it for the same reason). FIXES: - reserved-path-review.yml: add `# bp-required: pending #673` adjacent to the reserved-path-review job. Rationale: the self-merge guard IS intended to be branch-protection-enforced (that's its purpose — closes cp#673). But main BP currently has 0 reserved-path-review in status_check_contexts (only CI / all-required / E2E API Smoke / Handlers PG are pinned in .gitea/required-contexts.txt), so `bp-required: yes` would fail the in-BP verification. Therefore `bp-required: pending #673`: commit to enforcement, defer the actual BP-status-check-add to a separate operator follow-up (tracked via cp#673). The operator action is OUT OF SCOPE for the lint and this PR. - lint-shellcheck-arm64-pilot.yml: add `# bp-exempt: arm64-pilot shellcheck lane` adjacent to the shellcheck-arm64 job. The arm64 pilot is non-gating by design (internal#494, #233) — additive fast signal on the Mac mini runner, never blocks a merge. Pilot must not make main red (#2146). (Sibling ci-arm64-advisory.yml already has its bp-exempt directive; this fills the second arm64-pilot lane the lint flags.) NO production code change. The reserved-path-review gate logic and the shellcheck arm64-pilot logic are both untouched. The script is already un-tamperable (base-exec fix in prior commit c07e838c); this commit just makes the workflow's NEW status emission lint-compliant so lint-required-context-exists-in-bp goes green.
