Summary

This PR follows .agents/shortcuts/cut-minor-ga.md Phase 10, step 25. It registers the new 3.2.x maintenance line on main.

The branch 3.2.x already exists. It was created at c32bd78c5389753e3b8f3ffd8a1c04b777854d83, the v3.2.1 Version Packages merge (#7712). Patches on it continue as 3.2.2, 3.2.3, and so on.

Changes, adding 3.2.x to each branch list named in the runbook:

• release.yml:
  • the push trigger
  • the workflow_dispatch recovery case (main|3.2.x|3.1.x|3.0.x)
  • both storyboard verification gates, so 3.2.x gets the same current and 3.0-compat storyboard coverage as 3.1.x
• scripts/check-release-state.cjs and scripts/fence-changesets.cjs: the supported-branch lists
• build-check, changeset-check, codeql, dependency-review, apps-web-check: the push and PR branch filters
• Not included: training-agent-storyboards.yml. That path is protocol-scoped (fix(release): fence publication and recover superseded releases #7510), so changing it requires a changeset. A CI branch filter should not carry a release changeset, and the playbook forbids an empty one. Follow-up: add 3.2.x to it in the first 3.2.x backport that already carries a real patch changeset. The obvious candidate is the docs(adagents): define authorized_agents[].url as the full agent endpoint #7827 adagents clarification. Until then, release.yml still runs both storyboard gates on 3.2.x pushes.
• New forward-merge-3.2.yml: a straight 3.1.x → 3.2.x substitution of forward-merge-3.1.yml. It uses the same App token, the same one-way 3.2.x → main direction, and the same metadata-only auto-resolution. Its PR head is forward-merge/3.2.x.
• tests/release-workflow-immutability.test.cjs: covers forward-merge-3.2.yml and the new dispatch case

The matching 3.2.x PR

GitHub runs push and pull_request workflows from the copy on the target branch. A change on main alone therefore does not make pushes to 3.2.x run Release or forward-merge. The companion PR #7860 carries the identical diff. It also cherry-picks the post-tag GA hygiene onto 3.2.x: #7840, #7839, the v3.2.1 docs snapshot #7842, and #7843.

#7860 is the more urgent of the two. Cutting 3.2.x switched on tests/docs-nav-validation.test.cjs's comparison against origin/3.2.x, which still defaults its docs to 3.1. As a result, Canonical tests (2/4) now fails on every main PR, this one included, until #7860 lands.

Branch protection

No branch protection or ruleset covers 3.1.x today. The main and IPR signatures rulesets target ~DEFAULT_BRANCH only, and 3.1.x reports protected: false. Nothing was mirrored to 3.2.x. If the maintainer wants protection on maintenance lines, that is a separate admin decision.

Open decision (maintainer)

• How long 3.1.x stays a security and critical-fix line. The runbook and playbook leave this window to the maintainer.

• How fixes flow between 3.1.x, 3.2.x, and main. Forward merges today are 3.1.x → main and (with this PR) 3.2.x → main. Nothing moves a 3.1.x fix into 3.2.x. Options:

  • (a) Cherry-pick every fix to each affected line from its main merge. This is the current convention.
  • (b) Retarget forward-merge-3.1.yml to 3.1.x → 3.2.x, chaining into 3.2.x → main.

  Until that is decided, this PR leaves forward-merge-3.1.yml unchanged.

Test plan

• npm run test:release-workflow passes on this branch and on the 3.2.x companion branch.
• Every workflow YAML parses.
• CI green

Ladon verdict: Escalate to human review

Escalate — gated paths touched without required approval.

This PR mechanically registers the 3.2.x maintenance line across 11 CI/release files, including modifications to workflow files under .github/workflows/** and a new forward-merge-3.2.yml. The reviewer found no Critical/High/Medium findings — the diff is clean and well-covered by the immutability test.

However, gated_paths: true (multiple .github/workflows/** files modified) and review_decision: REVIEW_REQUIRED (not APPROVED). Per decision rule row 2, this is a hard, non-overridable approval gate that can only be satisfied by a real human/CODEOWNERS approval. The outcome must be escalate.

Escalation reasons

• .github/workflows/** is a gated path (modified: apps-web-check.yml, build-check.yml, changeset-check.yml, codeql.yml, dependency-review.yml, release.yml, training-agent-storyboards.yml; added: forward-merge-3.2.yml) and review_decision is REVIEW_REQUIRED. Human/CODEOWNERS approval is required before merge.

No blocking code findings; the gate lifts once a reviewer approves.

Why human review

• Gated path .github/workflows/** modified/added across 8 workflow files (including new forward-merge-3.2.yml) while review_decision is REVIEW_REQUIRED — human/CODEOWNERS approval required before merge.
• This PR touches a path under a hard, non-overridable approval gate (.github/workflows/apps-web-check.yml (modified) matches .github/workflows/**; .github/workflows/build-check.yml (modified) matches .github/workflows/**; .github/workflows/changeset-check.yml (modified) matches .github/workflows/**; .github/workflows/codeql.yml (modified) matches .github/workflows/**; .github/workflows/dependency-review.yml (modified) matches .github/workflows/**; .github/workflows/forward-merge-3.2.yml (added) matches .github/workflows/**; .github/workflows/release.yml (modified) matches .github/workflows/**; .github/workflows/training-agent-storyboards.yml (modified) matches .github/workflows/**) and the current GitHub review decision is 'REVIEW_REQUIRED', not APPROVED. This is a hard gate enforced in code — Ladon cannot auto-approve until a human/CODEOWNERS approval is recorded, regardless of how clean the diff is.
