test(canvas): add form-inputs coverage (35 cases) + Section accessibility fix

+ form-inputs.test.tsx: 35 cases across TextInput, NumberInput, Toggle, TagList, and Section — pure presentational components in the Config tab. Uses vi.hoisted() patterns from established suite; no jest-dom matchers. + form-inputs.tsx (Section): add aria-expanded + aria-controls to the collapsible toggle button for WCAG 2.1 AA compliance. The content div gets a stable id derived from the title; aria-controls links button to region. Indicator span gains aria-hidden="true" (decorative only).

+# review-check — evaluate whether a PR satisfies a single team-review gate.
+#
+# RFC#324 Step 1 of 5 — qa-review + security-review check workflows.
+#
+# This is the shared evaluator invoked by:
+#   .gitea/workflows/qa-review.yml      (TEAM=qa,      TEAM_ID=20)
+#   .gitea/workflows/security-review.yml (TEAM=security, TEAM_ID=21)
+#
+# Pass condition (per RFC#324 v1.1 addendum):
+#   ≥ 1 review on the PR where:
+#     • state == APPROVED
+#     • review.dismissed == false
+#     • review.user.login != PR.user.login (non-author)
+#     • review.user.login ∈ team-members
+#
+# Strict mode (default OFF for v1; see RFC trade-off note):
+#   If REVIEW_CHECK_STRICT=1, additionally require review.commit_id == PR.head.sha.
+#   With dismiss_stale_reviews: true at the protection layer, stale reviews
+#   are already dismissed, so the additional commit_id check is belt-and-
+#   suspenders. Keeping it off in v1 simplifies semantics; flip in a follow-up
+#   PR if reviewer telemetry shows residual stale-APPROVE merges.
+#
+# Privilege gate (RFC#324 v1.3 §A1.1 — INFORMATIONAL ONLY):
+#   The /qa-recheck and /security-recheck slash-commands can be triggered
+#   by anyone who can comment on the PR. The workflow's privilege step
+#   logs collaborator-status but does NOT gate execution of this script.
+#   Why this is safe: this evaluator is read-only and idempotent —
+#   reading `pulls/{N}/reviews` and `teams/{id}/members/{u}` can't be
+#   influenced by who triggered the run. If a real team-member APPROVE
+#   exists the gate flips green; otherwise it stays red. A
+#   non-collaborator commenting /qa-recheck cannot manufacture a green
+#   gate. Original (v1.2) design with `if:`-gating of this step was
+#   fail-open (skipped-via-`if:` job still publishes the status as
+#   `success`) — corrected in v1.3 per hongming-pc review 1421.
+#
+# Trust boundary (RFC A4):
+#   This script is loaded from the BASE branch (sourced via .gitea/scripts/
+#   on the workflow's checkout-of-base). It does NOT execute any PR-HEAD
+#   code. It only reads PR review state via the Gitea API.
+#
+# Token scope (RFC A1-α):
+#   The job's own conclusion (exit 0 / exit 1) is what publishes the
+#   `qa-review / approved` / `security-review / approved` status context.
+#   NO `POST /statuses` call here → NO `write:repository` scope on the
+#   token. `read:organization` (for team-membership probe) and
+#   `read:repository` (for PR + reviews) are enough.
+#
+# Required env:
+#   GITEA_TOKEN — least-priv read:repository + read:organization. See note
+#                 below about the team-membership API requiring the token
+#                 owner to be in the queried team (Gitea 1.22.6 quirk).
+#   GITEA_HOST  — e.g. git.moleculesai.app
+#   REPO        — owner/name (from github.repository)
+#   PR_NUMBER   — int (from github.event.pull_request.number or
+#                 github.event.issue.number for issue_comment events)
+#   TEAM        — short team name (qa | security) for log lines
+#   TEAM_ID     — Gitea team id (20=qa, 21=security at time of writing)
+#
+# Optional:
+#   REVIEW_CHECK_DEBUG=1 — per-API-call diagnostic lines
+#   REVIEW_CHECK_STRICT=1 — also require review.commit_id == pr.head.sha
+

+# qa-review — non-author APPROVE from the `qa` Gitea team required to merge.
+#
+# RFC#324 Step 1 of 5 (workflow-add). Pairs with `security-review.yml` and the
+# branch-protection flip in Step 2.
+#
+# === DESIGN (RFC#324 v1.1 addendum) ===
+#
+# A1-α (refire mechanism):
+#   Triggers on:
+#     - `pull_request_target`: opened, synchronize, reopened
+#         → initial status posts when PR opens / re-pushes
+#     - `issue_comment`: /qa-recheck slash-command on the PR
+#         → manual re-fire after a QA reviewer clicks APPROVE
+#           (Gitea 1.22.6 doesn't re-fire on pull_request_review, per
+#           go-gitea/gitea#33700 + feedback_pull_request_review_no_refire)
+#   Workflow name = `qa-review` ; job name = `approved`.
+#   The job's own pass/fail conclusion publishes the status context
+#   `qa-review / approved (<event>)` — NO `POST /statuses` call → NO
+#   write:repository token scope needed. Sidesteps internal#321 defect #2.
+#
+# A1.1 (privilege check on slash-comment — INFORMATIONAL ONLY, NOT a gate):
+#   The `issue_comment` event fires for ANY commenter, including
+#   non-collaborators. The original (v1.2) design gated the eval step
+#   behind a collaborator probe → if a non-collaborator commented
+#   /qa-recheck, the eval was `if:`-skipped → the job exited 0 anyway →
+#   the status context published `success` with ZERO real APPROVE.
+#   That was a fail-open: any visitor could green the gate.
+#
+#   RFC#324 v1.3 §A1.1 correction (option b per hongming-pc 1421):
+#   drop privilege-gating of the evaluation entirely. The eval is
+#   read-only and idempotent — it reads `pulls/{N}/reviews` and
+#   `teams/{id}/members/{u}` (both API-side state that a commenter can't
+#   change). Re-running it on a non-collaborator's comment is harmless
+#   AND correct: if a real team-member APPROVE exists, the eval flips
+#   green; if not, it stays red.
+#
+#   We KEEP the privilege step as a `::notice::` log line only — useful
+#   for griefer-spotting (one operator spamming /recheck) without
+#   touching the gate. If rate-limiting is needed later, add it as a
+#   separate concern (time-window throttle, not a privilege gate).
+#
+#   We MUST NOT use `github.event.comment.author_association` (the
+#   field doesn't exist on Gitea 1.22.6 webhook payload — this was
+#   sop-tier-refire's defect #1).
+#
+# A4 (no PR-head checkout under pull_request_target):
+#   We check out the BASE ref explicitly so the review-check.sh script is
+#   loaded from trusted source. We NEVER use `ref: ${{ github.event.pull_request.head.sha }}`.
+#   No PR-head code is executed in the runner. Trust boundary preserved.
+#
+# A5 (real Gitea team):
+#   `qa` team (id=20) verified by orchestrator preflight 2026-05-11; queried
+#   at run time via /api/v1/teams/20/members/{login}.
+#
+# === TOKEN ===
+#
+# The workflow reads PR state, PR reviews, and team membership.
+# Gitea 1.22.6's /api/v1/teams/{id}/members/{u} returns 403 ('Must be a
+# team member') for tokens whose owner is not in that team. The default
+# `secrets.GITHUB_TOKEN` is owned by a workflow-scoped identity that is
+# also not in qa/security teams → also 403.
+#
+# Resolution: a dedicated `RFC_324_TEAM_READ_TOKEN` secret, owned by an
+# identity that IS in both `qa` and `security` teams (Owners-tier
+# claude-ceo-assistant, or a new service-bot added to both teams).
+# Provisioning of this secret is tracked as a follow-up issue (filed by
+# core-devops at PR open).
+#
+# Until that secret is provisioned, the job will exit 1 with a clear
+# 403-on-team-probe error and the `qa-review / approved` status will
+# stay `failure`. This is the correct fail-closed behavior — the gate
+# blocks merge until both (a) a QA team member APPROVEs and (b) the
+# workflow has a token that can confirm their team membership.
+#
+# === SLASH-COMMAND CONTRACT ===
+#
+#   /qa-recheck   — re-evaluate the gate (e.g. after an APPROVE lands)
+#
+# Open to any PR commenter. The eval is read-only and idempotent, so
+# unprivileged refires are harmless (RFC#324 v1.3 §A1.1). Collaborator
+# status is logged for griefer-spotting but does NOT gate execution.

+ *   - Toggle calls onChange with boolean on toggle
+ *   - TagList renders existing tags with remove buttons
+ *   - TagList × button has aria-label "Remove tag {value}"

+# Publish-runtime pipeline verification — 2026-05-11
+
+Marker file for the canonical end-to-end pipeline verification after
+`publish-runtime-bot` provisioning (internal#327) + stale-tag drift
+resolution (`runtime-v0.1.131` deleted from main).
+
+## Purpose
+
+Triggers `workspace/**` path filter on `publish-runtime-autobump.yml`,
+exercising the full pipeline:
+
+1. `publish-runtime-autobump / bump-and-tag` reads PyPI version, computes
+   next, pushes tag `runtime-v0.1.131` (or higher) using new bot scope.
+2. `publish-runtime.yml` fires on tag, builds + publishes to PyPI.
+3. Cascade autobump: 9 template repos get their `.runtime-version`
+   pinned to the new version.
+
+## Acceptance criteria
+
+- [ ] autobump bump-and-tag context green on merged commit
+- [ ] tag `runtime-v0.1.131` (or computed next) exists on molecule-core
+- [ ] publish-runtime.yml run green
+- [ ] PyPI molecule-ai-workspace-runtime updated from 0.1.130
+- [ ] 9 template repos updated their pinned runtime version
+
+## Rollback
+
+This file is informational only — no code dependency. Safe to delete
+in any future PR once pipeline is proven stable.
