fix(canary-rollout): autocut cuts inline via gh-api — no sibling cut-release.sh (#633)#634
Conversation
…release.sh (#633) The #613 relocation moved the canary-rollout engine to .github but left cut-release.sh in .github-private. autocut (#1069) execs ${_HERE}/cut-release.sh, which no longer exists on this checkout, so every scheduled cut best-effort-fails and silently reopens the last manual seam — green run, no candidate cut. (Latent today only because all reusables are currently unchanged; CANARY_AUTO_CUT=true is live.) Make the engine self-contained: cut inline via the App-token gh-api path (new _gh_create_annotated_tag + existing _gh_move_tag) against the agent's registry HOST (already resolved correctly in _autocut_agent). This also fixes a second latent defect — cut-release.sh's this_repo() would have resolved dev-lead to GITHUB_REPOSITORY (.github) when its reusable lives in .github-private. cut-release.sh stays in .github-private as the manual CLI. Tests: reworked the autocut bats to assert the inline create+move hit the right host (dev-lead → .github-private, auto-rebase → .github) via a gh-write log; 91/91 pass. shellcheck clean.

Code Review
This pull request refactors the autocut process in scripts/canary-rollout.sh to cut releases inline via the GitHub API instead of shelling out to the external cut-release.sh script, making the engine self-contained. The tests in tests/canary_rollout.bats have been updated to stub and assert on these inline API calls. Feedback was provided to improve the robustness of the new _gh_create_annotated_tag function by handling potential "null" string outputs from jq and avoiding silencing stderr on command failures.

Pull request overview
This PR fixes a regression introduced by relocating the canary-rollout engine into petry-projects/.github: autocut previously shelled out to a sibling cut-release.sh that no longer exists in this repo, causing scheduled runs to remain green while silently failing to cut new candidates. The fix makes the engine self-contained by cutting releases inline via GitHub API calls using the App token, targeting each agent’s registry host (including .github-private-hosted agents like dev-lead).
Changes:
- Replace
autocut’s dependency oncut-release.shwith inline GitHub API primitives (create annotated tag + movenext). - Add
_gh_create_annotated_taghelper and updateautocutflow to be idempotent and host-correct. - Rework
autocutbats tests to assert gh-api write behavior (host correctness) via a write log.

Summary
Fixes autocut silently broken by the #613 relocation: replaces the exec of a cut-release.sh that no longer exists in this repo with an inline App-token gh-api cut (_gh_create_annotated_tag + existing _gh_move_tag) against each agent's registry host. Also fixes the latent wrong-host defect for dev-lead. Idempotency and invariant-guard branches are implemented and covered by new bats tests. All CI green; both defects from #633 addressed.
Linked issue analysis
Closes #633. The issue describes two defects: (1) autocut execs ${_HERE}/cut-release.sh which stayed in .github-private after the #613 relocation, so scheduled cuts best-effort-fail silently; (2) even if present, cut-release.sh's this_repo() would resolve dev-lead to GITHUB_REPOSITORY (.github) instead of its actual host (.github-private). The PR substantively addresses both: the cut now runs inline via the App-token gh-api path against the host already resolved by _autocut_agent from the registry. cut-release.sh remains untouched in .github-private as the manual CLI, avoiding duplication.
Findings
- Correctness verified: _gh_tag_commit properly dereferences annotated tag objects to commit SHAs, so the idempotent-retry comparison (existing tag sha vs mainsha) is sound.
- No exit-status masking: obj is declared local on a separate line before the command-substitution assignment, so the $? check after _gh_create_annotated_tag's first gh api call is valid; --jq '.sha // empty' handles null.
- Invariant guard: if the computed release tag exists but points to a different commit, the engine warns and skips the next move rather than advancing next to an untagged commit — covered by a dedicated bats test.
- Prior bot review threads: gemini (null/stderr handling) and copilot (unconditional next move) are resolved. Copilot's test-coverage thread is unmarked but substantively addressed — both requested regression tests (idempotent retry; stale-tag mismatch) exist in the head diff. Residual nit: the _gh_create_annotated_tag failure branch (warn-and-continue) is untested; low severity, best-effort path.
- Workflow file change is comment-only (2 lines); no behavioral or security-relevant change to canary-rollout.yml.
- Secret scan: run_secret_scanning MCP tool unavailable in this environment; gitleaks CI check passed. No credentials or token handling changes in the diff.
- Triage assessment confirmed with one adjustment: risk is MEDIUM (non-trivial logic change in release automation), not LOW — still within auto-approve range.
CI status
All required checks green at head ea7b759: Lint, ShellCheck, Agent Security Scan, Secret scan (gitleaks), CodeQL, SonarCloud (Quality Gate passed, 0 issues), Dependency audit, AgentShield, CodeRabbit. Two CANCELLED dev-lead check runs were superseded by later successful runs of the same jobs. 91/91 bats reported passing.

…o-local-git invariant
The dev-lead fix-review commit added an error message containing the literal
"git tag", which the #1076 invariant test ("no local git tag/push in the move
paths") greps for on non-comment lines — a false positive, but a red bats run
(and bats isn't a required check, so CI wouldn't have caught it). Reword to
drop the "git tag" token; behavior unchanged. 93/93 bats, shellcheck clean.

Review mode: triage-approved (single reviewer)
Summary
Fixes the silently-broken autocut after the #613 relocation: the engine no longer execs a sibling cut-release.sh (left behind in .github-private) and instead cuts candidates inline via the App-token gh-api path — a new _gh_create_annotated_tag (create annotated tag object + publish ref) plus the existing _gh_move_tag, both against the agent's registry host. This also fixes the second latent defect (dev-lead would have been cut against GITHUB_REPOSITORY instead of its .github-private host). The triage tier's clearance is confirmed; risk is graded MEDIUM (non-trivial logic change in release automation) rather than LOW, but all approval gates pass.
Verified in detail:
- Idempotency check is sound: the pre-cut probe uses
_gh_tag_commit, which correctly dereferences annotated tag objects to the commit SHA (scripts/canary-rollout.sh:98-108), so comparingexisting_shatomainshais valid for retries after a partial cut. - Invariant guard is correct: if the release tag exists but points elsewhere (manual retag / concurrent run), the engine warns and skips the
nextmove rather than advancingnextto an untagged commit. set -euo pipefailinteraction is safe:_gh_create_annotated_tagis only invoked in a conditional context (elif !inside_autocut_agent, itself called with|| echo warningat line 970), so its non-zero returns and the$?-after-assignment check behave as intended;[ -z "$obj" ]also independently catches a failed create.- Best-effort contract preserved: every failure path warns and
return 0s, so the scheduled tick never fails. - Tests are meaningful: the bats stub now logs mutating gh-api writes (GH_LOG) instead of stubbing
cut-release.sh, and asserts host-correct writes (dev-lead →.github-private, auto-rebase →.github). Two new tests cover the idempotent-retry branch and the tag-mismatch invariant branch. - Workflow change is comment-only (canary-rollout.yml).
cut-release.shremains untouched in.github-privateas the runbook CLI — no duplication.
Linked issue analysis
Closes #633 — substantively addressed. Both defects from the issue are fixed: (1) the nonexistent ${_HERE}/cut-release.sh exec is replaced by the inline gh-api cut, and (2) the wrong-host resolution for this-repo agents is avoided because _autocut_agent uses the registry host for both the create and the move.
Findings
No blocking findings.
- Nit (non-blocking): the ref-publish call in
_gh_create_annotated_tagdiscards stderr (>/dev/null 2>&1), so the underlying API error is lost — only the generic::errorline surfaces. Consider capturing stderr for diagnosis on a future pass. - Secret scan (MCP):
run_secret_scanningtool not available in this environment — noted per protocol; gitleaks CI coverage still applies. No secret-like content in the diff.
CI status
All checks green: CodeQL ✓, Analyze (actions) ✓, CodeRabbit neutral (final review state: APPROVED), dependabot-automerge skipped (N/A). SonarQube quality gate passed. 0 unresolved review threads; prior Copilot/CodeRabbit/Gemini feedback was addressed across commits 500bcc2–7ad251a (idempotency tests added in ea7b759).
