chore: repin centralized stubs to ring1 ring channel (#870)

[don-petry]

Repins this repo's #482 reusable caller stubs onto the canary-ring <name>/ring1 channels (epic #495).

The ring1 channels were cut at the currently-running proven version (376a4fcb), so this is a zero-behavior-change repin — promotion to newer code is a separate soak-gated step. The ring-aware audit (petry-projects/.github#529, merged) already accepts these channels, so dev-lead remediation will not revert them (#482 lesson).

Your organization has used up its prepaid credits, and credit purchases are no longer available. Enable the review add-on in the billing tab to keep reviews running — you're only billed for reviews past your plan's rate limits ($0.25/file).

⌛ How to resolve this issue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based credits.

🚦 How do rate limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please see our Fair Usage Limits Policy for further information.

Summary

Zero-behavior-change repin: 6 reusable-workflow caller stubs moved from their prior mutable refs (@v2 / @/stable) onto the org's canary-ring @/ring1 channels (epic #495). The ring1 channels were cut at the currently-running proven version (376a4fcb), so no code actually changes — promotion to newer code is a separate soak-gated step. These are first-party petry-projects/.github reusable workflows (not third-party actions), and the change is consistent with the pre-existing channel-pinning pattern rather than a regression from SHA pinning.

Linked issue analysis

No closing issue (closingIssuesReferences empty). PR references #870 (chore), epic #495 (ring rollout), and #482 (lesson). The ring-aware compliance audit (petry-projects/.github#529, merged) already accepts these channels, so dev-lead remediation will not revert them — the dev-lead bot already posted a no-changes-needed result. Nothing to substantively address; this is a routine infrastructure repin.

Findings

No issues found. Diff is 6 single-line uses: ref changes across .github/workflows/*.yml, each +1/-1. No secrets, logic, or permission changes. GitHub secret-scanning MCP tool not exposed in this run; not material here since the diff contains only workflow ref strings. gitleaks CI check passed independently.

CI status

All checks green. SUCCESS: gitleaks secret scan, CodeQL (actions + python), AgentShield, SonarCloud (Quality Gate passed, 0 new issues), dependency-audit, dev-lead, pr-auto-review, review. Remaining checks SKIPPED (no failures). Advisory bots Codex/CodeRabbit were rate-limited and Gemini does not support these file types — no findings from any; SonarCloud is the substantive advisory pass.

CI Failure: SonarCloud Code Analysis

Step: SonarCloud Code Analysis (quality gate)
Root cause: Config error

The PR modifies only .github/workflows/*.yml files, swapping all reusable workflow refs from stable tags (@v2, @stable) to ring1 canary branches (e.g. @agent-shield/ring1). SonarCloud is an external quality gate that runs against the full branch and enforces thresholds (coverage, duplication, reliability). Because no application source code changed, the failure most likely indicates either a pre-existing quality gate condition that is now surfaced on this branch, or the SonarCloud scan workflow itself depends on one of the reusable workflows being pinned to a stable ref that was just changed to a ring1 ref, causing the scan to behave unexpectedly.

Suggested fix: Revert one of the workflow refs (e.g. the SonarCloud-triggering workflow) back to its stable tag to confirm whether the ring1 ref is the cause, then file a separate PR to bump ring1 refs once the quality gate passes on main.

Summary

Repins 6 reusable-workflow caller stubs from pre-ring pins onto the canary-ring <name>/ring1 channels (epic #495). 5 of 6 are genuinely zero-behavior-change, but the auto-rebase stub is a 92-commit rollback that removes eligibility-gating logic — contradicting the PR's stated rationale. Escalating for human confirmation.

Linked issue analysis

No closingIssuesReferences. PR is a mechanical org-wide repin (Refs #870; builds on #482/#495; relies on ring-aware audit #529 already merged). No single issue to verify substantively; assessed on its mechanical correctness instead.

Findings

[MEDIUM] auto-rebase repin is a behavior-changing rollback, not zero-change.
Verified all six ring1 channels exist as tags pinned to 376a4fcb (the "proven version" the PR cites). For 5 of 6 stubs the prior pin already resolved to 376a4fcb, so those are true no-ops:

• agent-shield @v2→@agent-shield/ring1 (v2 tag = 376a4fcb) ✓
• dependabot-automerge @v2→ring1 ✓
• dependabot-rebase @dependabot-rebase/stable→ring1 (stable = 376a4fcb) ✓
• dependency-audit @v2→ring1 ✓
• pr-review-mention @v2→ring1 ✓

However, auto-rebase moves @auto-rebase/stable → @auto-rebase/ring1. These resolve to different commits:

• auto-rebase/stable = acec8959 (currently running)
• auto-rebase/ring1 = 376a4fcb

gh api compare 376a4fcb...acec8959 → ahead_by: 92, behind_by: 0 (376a4fcb is an ancestor; stable is 92 commits newer). Affected files in that delta include the auto-rebase logic itself:

• .github/workflows/auto-rebase-reusable.yml: +88 / −3
• .github/scripts/auto-rebase/lib/eligibility.sh: added (+67) — absent at 376a4fcb.

So repinning auto-rebase to ring1 reverts ~88 lines of reusable-workflow logic and removes the eligibility-gating library on a workflow that holds contents: write. The PR's "zero-behavior-change … cut at the currently-running proven version" claim is accurate for the 5 @v2/stable=376a4fcb stubs but NOT for auto-rebase, whose stable channel had advanced ahead of the ring cut point.

This may be intentional (consolidate everything onto the ring baseline, re-promote later via the "separate soak-gated step" the PR mentions). But silently rolling back auto-rebase eligibility gating is a safety-relevant behavior change that a human should confirm before merge — it could re-enable auto-rebase on PRs the newer eligibility logic was designed to exclude.

No secrets, no permission-block changes, no untrusted/third-party actions introduced; all refs are first-party (petry-projects/.github). gitleaks CI check passed; secret-scanning MCP tool not available in this run (skipped, non-blocking).

CI status

All checks green or skipped — no failures. Notable SUCCESS: Secret scan (gitleaks), CodeQL, Analyze (actions), Analyze (python), SonarCloud, agent-shield, dependency-audit detect, review/review. reviewDecision=APPROVED. Advisory bots (CodeRabbit/Gemini/Codex) were rate-limited/unsupported — informational only.
