cmd_rollback selects the scoped tag when available, falls back to the bare tag, and fails if neither exists. Output and the API update use the selected tag. |
Test scoped and fallback behavior tests/canary_rollout.bats |
Tests verify scoped-tag selection, failure when both tags are absent, and fallback to the bare tag. |

Explanation
Issue
#1103requirescmd_rollbackto use_resolved_channel. The supplied change still describes a rollback-specific probe of the v-scoped tag followed by a bare-tag fallback. This does not preserve the shared resolver result when a v-scoped channel family is selected. The incremental changes since the previous review only rename repository strings, so they do not correct this gap. The exact dry-run ref and missing-tag error objectives have focused test coverage, but the resolver requirement remains unmet.Resolution
Use
_resolved_channelas the only channel-resolution path. If it selectsdev-lead/v139-stable, fail when that exact ref is absent instead of falling back todev-lead/stable. Keep the bare-tag fallback test without av<M>-nextanchor. Keep the fail-loud assertion for the scoped-tag case. Run the full lint and BATS checks after the fixture changes.

Code Review
This pull request updates the rollback command in scripts/canary-rollout.sh to resolve ring tags in a v-scope-aware manner, matching the behavior of promotions and preventing silent no-ops. It also introduces loud failures when a resolved ring tag does not exist, accompanied by comprehensive BATS tests. The review feedback suggests asserting the exact expected non-zero exit status in the BATS tests rather than using a generic non-zero check to prevent false positives.

Reviewed commit: 1d3987d009ca177fd781db3a64bed7909f30e28c
Review mode: triage-approved (single reviewer)
Summary
Fixes #1103: cmd_rollback now resolves the ring tag v-scope-aware via _resolved_channel (prefer /v-, fall back to bare), matching cmd_promote. Dry-run output names the exact ref to be PATCHed, and a resolved-but-absent ring tag now fails loudly instead of silently moving a tag nobody pins. 21/-5 lines in scripts/canary-rollout.sh plus 83 lines of bats regression tests covering the v-scoped, legacy-fallback, and missing-tag shapes.
Linked issue analysis
Linked issue #1103 (silent no-op rollback on v-scoped agents) is substantively addressed. Acceptance criteria: (1) ring tag resolved the same way as cmd_promote/_resolved_channel — done, verified _resolved_channel emits tagcommit which the new IFS=$'\t' read consumes correctly; (2) dry-run names the exact ref — done; (3) fail loudly rather than no-op when the resolved tag is absent — done (::error:: + return 1); (4) audit of other subcommands — the issue itself records promote/evaluate/drift as already correct; (5) regression test with the real shape (major 139, v139-* family) — done.
Findings
No blocking findings. Non-blocking notes: (a) three unresolved bot review threads (gemini: assert exact exit code in bats; codeant: _resolved_channel derives major from highest release rather than caller pin, and _channel_tag_commit masks API outages as empty) — the latter two describe pre-existing behavior of shared helpers that this PR intentionally reuses for parity with cmd_promote, and the dev-lead agent reviewed them and posted no-changes; (b) codeant nitpicks on test stubs are test-quality suggestions, not defects. Secret-scan MCP tool unavailable in this session; gitleaks CI check passed.
CI status
All code checks green: Lint, ShellCheck, Canary-rollout bats, CodeQL (incl. actions analysis), Secret scan (gitleaks), Agent Security Scan, AgentShield, SonarCloud quality gate, duplicate-decl-gate, dependency-audit. A few dev-lead dispatch/ci-relay/resume runs show CANCELLED — superseded agent-orchestration runs, not code checks. mergeStateStatus is BEHIND (branch needs update against main) but mergeable.

Summary
Fixes #1103: cmd_rollback now resolves the ring tag v-scope-aware via _resolved_channel (prefer /v-, fall back to legacy bare), matching cmd_promote. Dry-run names the exact ref to be PATCHed, and a resolved-but-absent ring tag fails loudly (::error:: + exit 1) instead of silently moving a tag nobody pins. +21/-5 in scripts/canary-rollout.sh plus 83 lines of bats regression tests. This confirms the prior approval at 1d3987d: the only deltas are a merge from main and one test-assertion fix ([ "$status" -ne 0 ] → -eq 1) addressing Gemini's review feedback.
Linked issue analysis
Linked issue #1103 (silent no-op rollback on v-scoped agents) is substantively addressed against all acceptance criteria: (1) ring tag resolved the same way as cmd_promote/_resolved_channel — verified: _resolved_channel emits tagcommit, consumed via IFS=$'\t' read identically to the three pre-existing call sites; (2) dry-run output names the exact ref — done; (3) fail loudly rather than no-op when the resolved tag is absent — done; (4) audit of other subcommands — the issue itself records promote/evaluate/drift as already correct; (5) regression test with the real shape (major 139, v139-* family, rollback must target v139-stable) — done, plus legacy-bare-fallback and missing-tag cases.
Findings
No blocking findings. The prior review's only actionable item (Gemini: assert exact exit code in the missing-tag bats test) is resolved in commit a547522 — the test now asserts [ "$status" -eq 1 ]. Remaining CodeAnt suggestions (_resolved_channel derives major from the highest release rather than a caller pin; _channel_tag_commit masks API outages as empty output) describe pre-existing behavior of shared helpers this PR intentionally reuses for parity with cmd_promote — carried as non-blocking, consistent with the prior review; the dev-lead agent reviewed and posted no-changes for them. CodeAnt nitpicks on test stubs are test-quality suggestions, not defects. Secret-scan MCP tool unavailable in this session; noted per protocol — gitleaks CI check passed and the diff contains only placeholder SHAs.
CI status
All checks green at a547522 (waited for in-progress runs to finish): Lint, ShellCheck, Canary-rollout bats (Lint and bats), CodeQL (actions analysis), Secret scan (gitleaks), Agent Security Scan, AgentShield, SonarCloud quality gate + Code Analysis, duplicate-decl-gate, dependency-audit (npm audit passed; other ecosystems skipped), CodeRabbit context SUCCESS. Skipped jobs are conditional agent-orchestration/dependabot steps, not code checks. Mergeable; mergeStateStatus BLOCKED only pending required review.

Summary
Fixes #1103: cmd_rollback previously moved the bare <agent>/<ring> tag even when the fleet pins the v-scoped <agent>/v<M>-<ring> tag, making the emergency rollback a silent no-op that exits 0. The fix resolves the ring tag through _resolved_channel — the exact same v-scope-preferring path used by cmd_promote — and refuses loudly (exit 1) when the resolved tag does not exist, rather than create-and-moving a tag nobody pins. Dry-run output now names the exact ref to be PATCHed. The change is small (2 files, +104/−5), well-commented, and covered by three targeted bats regression tests mirroring the real shape from the issue (dev-lead on major 139).
Linked issue analysis
Linked issue #1103 is substantively addressed. All acceptance criteria are met: (1) ring tag resolved identically to cmd_promote/_resolved_channel — prefer <agent>/v<M>-<ring>, fall back to bare; (2) dry-run names the exact ref (refs/tags/dev-lead/v139-stable vs .../stable is now visible to the operator); (3) fail-loud instead of silent no-op when the resolved tag is absent; (4) the issue itself audited promote/evaluate/drift as already correct, so no further subcommand changes were needed; (5) regression test with the real shape (major 139, v139-* family present) asserts the v-scoped tag is targeted and the bare tag never is.
Findings
No blocking findings.
- Verified
_resolved_channelemits<tag>\t<commit>; theIFS=$'\t' read -r ring_tag ring_commitparse is correct, including the absent-tag case (empty commit → loud refusal). - Tests correctly stub
ghto distinguish the v-scoped, bare, and absent-tag shapes, and assert the bare tier is never the PATCH target on a v-scoped agent. - Two unresolved CodeAnt bot threads remain; both were triaged by the dev-lead fix-bot-comment pass (no-changes) and I concur they are non-blocking:
- "_resolved_channel derives the tag from the highest release major, not the caller's channel major" — this is the documented, issue-mandated behavior (epic #657 F4), identical to cmd_promote; rollback's CLI takes a bare ring name and there is no "caller channel major" input. A design critique of pre-existing shared infrastructure, not a defect of this PR.
- "_channel_tag_commit hides GitHub read failures as empty output" — pre-existing behavior of the shared helper used by all subcommands. Under this PR the failure mode is fail-closed (refuse with a clear error) rather than the prior silent wrong-tag move, which is strictly safer. Distinguishing 404 from transient API failure is a reasonable follow-up, out of scope here.
- Secret scan: the run_secret_scanning MCP tool is not available in this environment; the gitleaks CI check passed and the diff contains only dummy test oids.
CI status
All required checks green: ShellCheck ✓, Lint and bats ✓, CodeQL ✓, Agent Security Scan ✓, AgentShield ✓, Secret scan (gitleaks) ✓, SonarCloud Quality Gate ✓, duplicate-decl-gate ✓, AGENTS.md Self-Check ✓. Remaining skips are ecosystem-not-present audits (npm/pip/cargo/go) and dependabot-automerge — expected.

Superseded by automated re-review at a547522.
The three new rollback tests were missing the v<M>-next channel anchor tags in their gh stubs. These anchors are required for _agent_current_channel_major to detect the release major and enable v-scoped channel tag resolution. Without them, _resolved_channel would fall back to bare tags, causing test 112 to fail. Added v139-next stubs and handlers to all three tests so they properly exercise v-scoped channel resolution as intended. Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>

- Line 1276: Remove the `v139-next` scoped tag from the `matching-refs` fixture
so it lists only `v139.8.0`. Keep the bare `stable` tag and existing output
assertions unchanged, ensuring this test exercises bare channel resolution
rather than the scoped-channel fallback.
- Around line 1242-1266: Update the rollback test for the missing resolved ring
tag to assert that the error names dev-lead/v139-stable, since the v139-next
anchor makes the scoped tag authoritative. Align the explanatory comment with
that expectation and keep the existing fail-loud assertions.
- Around line 1208-1240: Update the rollback test using the established-major
fixture to exercise the actual PATCH path, not only dry-run output. Record the
PATCH request made during `cmd_rollback`, then assert it targets
`dev-lead/v139-stable` and never `dev-lead/stable`.

Exercise the non-dry-run rollback PATCH target.
All three rollback tests use --dry-run. A regression that keeps the scoped tag in the dry-run output but passes the bare tag to _gh_move_tag would pass these tests. The direct _gh_move_tag tests validate only the helper, not cmd_rollback's selected tag.
Add one non-dry-run invocation to the established-major fixture and assert that the PATCH target is dev-lead/v139-stable, not dev-lead/stable.

Update the rollback test using the established-major fixture to exercise the
actual PATCH path, not only dry-run output. Record the PATCH request made during
`cmd_rollback`, then assert it targets `dev-lead/v139-stable` and never
`dev-lead/stable`.

Assert the authoritative scoped tag in test 113.
The v139-next anchor makes dev-lead/v139-stable authoritative. The current dev-lead/stable assertion accepts the incorrect bare-tag fallback. Require the scoped missing tag and keep the existing fail-loud assertions.

Update the rollback test for the missing resolved ring tag to assert that the
error names dev-lead/v139-stable, since the v139-next anchor makes the scoped
tag authoritative. Align the explanatory comment with that expectation and keep
the existing fail-loud assertions.

Remove the scoped anchor from the bare-path fixture.
v139-next makes _resolved_channel select the scoped channel family. The assertion can then pass through cmd_rollback’s secondary fallback without testing bare resolution. List only v139.8.0 in matching-refs; keep the bare stable tag and existing output assertions.

Remove the `v139-next` scoped tag from the `matching-refs` fixture so it lists
only `v139.8.0`. Keep the bare `stable` tag and existing output assertions
unchanged, ensuring this test exercises bare channel resolution rather than the
scoped-channel fallback.
