ci: verify publish-runtime pipeline end-to-end (internal#327)
Marker file triggers workspace/** path filter on publish-runtime-autobump.yml, exercising the full runtime publish pipeline after publish-runtime-bot provisioning + stale-tag resolution. Acceptance: bump-and-tag green, tag exists, publish-runtime.yml green, PyPI updated, 9 template repos updated. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

+# 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)

+#   T3: PR open + tier:low but NO approving reviews → sop-tier-check
+#       exits non-zero; refire POSTs status=failure.
+#   T4: PR CLOSED → refire exits 0 with no status POST (no-op on closed).
+#   T5: Rate-limit — recent status update within 30s → refire skips,
+#       no new POST.
+#   T6 (yaml-lint): workflow `if:` expression contains author_association
+#       gate + slash-command-trigger gate + PR-not-issue gate.
+#   T7 (yaml-lint): workflow file is parseable YAML.
+#
+# Tests T1-T5 run the real script against a local-fixture HTTP server

+#
+# 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

+# sop-tier-refire — issue_comment-triggered refire of sop-tier-check.
+#
+# Closes internal#292. Gitea 1.22.6 doesn't refire workflows on the
+# `pull_request_review` event (go-gitea/gitea#33700); the `sop-tier-check`
+# workflow's review-event subscription is silently dead. The result:
+# PRs that get their approving review AFTER the tier-check ran on open/
+# synchronize keep their failing status check forever, and the only way
+# to merge is the admin force-merge path (audited via `audit-force-merge`
+# but the audit trail keeps growing; see `feedback_never_admin_merge_bypass`).
+#
+# Workaround pattern from `feedback_pull_request_review_no_refire`:
+# `issue_comment` events DO fire reliably on 1.22.6. When a repo
+# MEMBER/OWNER/COLLABORATOR comments `/refire-tier-check` on a PR, this
+# workflow re-runs the sop-tier-check logic and POSTs the resulting
+# status to the PR head SHA directly. No empty commit, no git history
+# bloat, no cascade re-fire of every other workflow on the PR.
+#
+# SECURITY MODEL:
+#
+# 1. `pull_request` exists on the issue (issue_comment fires on issues
+#    AND PRs; we only want PRs).
+# 2. `comment.author_association` must be MEMBER/OWNER/COLLABORATOR.
+#    Per the internal#292 core-security review (review#1066 ask): anyone
+#    can comment, but only repo collaborators+ can flip the status.
+#    Without this gate, a drive-by commenter on a public-issue-tracker
+#    surface could trigger a status flip.
+# 3. Comment body must contain `/refire-tier-check` — a slash-command-
+#    shaped trigger (not just any comment word). Prevents accidental
+#    triggering from prose like "we should refire tests" in a review.
+# 4. This workflow does NOT check out PR HEAD code. Like sop-tier-check,
+#    it only HTTP-calls the Gitea API. Trust boundary preserved.
+#
+# Note: `issue_comment` fires from the BASE branch's workflow file. There
+# is no `pull_request_target` equivalent to set; the trigger inherently
+# loads the workflow from the default branch.
+#
+# Rate-limit: a 1s pre-sleep + a "skip if status posted in last 30s"
+# guard prevents comment-spam from thrashing the status. See the script.

+ *   - Empty state ("No memory entries")
+ *   - Memory entries list renders
+ *   - Expand/collapse entry + aria-expanded
+ *   - Add entry: key validation, value JSON parsing, TTL
+ *   - Edit entry: begin, cancel, save, 409 conflict
+ *   - Delete entry: optimistic removal
+ *   - Error state from API failure
+ *   - Refresh button triggers reload
+ *   - Awareness dashboard collapse/expand
+ *   - Advanced toggle shows/hides KV section
+ *   - Awareness URL includes workspaceId
+ *
+ * Uses vi.useRealTimers() + flush() pattern for all non-window tests.
+ * window.open is mocked per-test since it is environment-dependent.

+ *   - Toggle enable/disable via status dot
+ *   - Delete via ConfirmDialog

+ *   - Form validation (disabled when cron/prompt empty)
+ *   - Create POST with correct payload
+ *   - Edit PATCH with correct payload
+ *   - Error state surfaces API failures
+ *   - Auto-refresh every 10s (spy)
+ *   - cronToHuman formatting
+ *   - relativeTime formatting
+ *   - Reset form clears all fields
+ *   - Disabled schedules are visually dimmed

+# Gitea Actions operational quirks (molecule-core)
+
+Documents persistent operational findings about Gitea Actions runner behaviour
+that differ from GitHub Actions and require workarounds in workflow YAML or
+runbooks.
+
+> Last updated: 2026-05-11 (core-devops-agent)

+
+## Large repo causes fetch timeout on Gitea Actions runner
+
+### Finding
+
+The Gitea Actions runner (container on host `5.78.80.188`) can reach the git
+remote (`https://git.moleculesai.app`) over HTTPS — a single-commit shallow
+fetch (`--depth=1`) succeeds in ~16 s. However, fetching the **full compressed
+repo history** (~75+ MB) exceeds the runner's network timeout window (~15 s).
+
+This is **not a Gitea Actions bug** and **not a network isolation policy** —
+it is a repo-size constraint. The runner can reach external hosts (GitHub,
+Docker Hub, PyPI) without issue.
+
+### Impact
+
+Workflows that rely on `actions/checkout` with `fetch-depth: 0` (full history)
+or `git clone` will time out.
+
+Specifically:
+- `actions/checkout@v*` with `fetch-depth: 0` hangs (fetching full repo
+  history takes >15 s before hitting the timeout).
+- `git clone <url>` hangs for the same reason.
+- `git fetch origin <ref> --depth=1` **succeeds** in ~16 s — this is the
+  working pattern.
+
+### Affected workflows
+
+| Workflow | Issue | Workaround |
+|---|---|---|
+| `harness-replays.yml` detect-changes job | `fetch-depth: 0` + `git clone` time out | Added `timeout 20 git fetch origin base.ref --depth=1` + `continue-on-error: true` + fallback to `run=true` per PR #441 |
+| `publish-workspace-server-image.yml` | In-image `git clone` of workspace templates | Pre-clone manifest deps before compose build (Task #173 pattern) |
+| Any workflow using `fetch-depth: 0` | Full history fetch times out | Use `fetch-depth: 1` + explicit `git fetch` for needed refs |
+
+### How to diagnose
+
+```bash
+# From inside the runner (add as a debug step):
+timeout 20 git fetch origin main --depth=1
+# If this SUCCEEDS (~16s): runner can reach the git remote — the repo is
+#   too large for full-history fetch.
+# If this times out: true network isolation (unlikely; check firewall rules).
+```
+
+### Verification
+
+Confirmed 2026-05-11 by running `timeout 20 git fetch origin base.ref --depth=1`
+in the `detect-changes` job of `harness-replays.yml` — **succeeds in ~16 s**.
+Runner can reach `https://api.github.com` and `https://pypi.org` without issue,
+confirming this is a repo-size constraint, not network isolation.

+## `continue-on-error` only works at step level, not job level
+
+### Finding
+
+Gitea Actions (1.22.6) does not honour `continue-on-error: true` at the **job**
+level the way GitHub Actions does. A job with `continue-on-error: true` that
+fails still reports `status: failure` in the commit status API.
+
+Only `continue-on-error: true` at the **step** level works as expected.
+
+### Impact
+
+If you want a job to always "pass" in the status API (so dependent jobs can
+run and the overall CI does not show `failure`), you must add
+`continue-on-error: true` to every step that can fail, AND ensure each step
+exits with code 0 (e.g., append `|| true` to commands that might fail).
+
+### Affected workflows
+
+| Workflow | Fix |
+|---|---|
+| `harness-replays.yml` detect-changes | Added `continue-on-error: true` to fetch step + decide step; added `|| true` to `DIFF=$(git diff ...)` per PR #441 |
+
+### How to diagnose
+
+```yaml
+# WRONG — job reports as failure despite flag
+jobs:
+  my-job:
+    continue-on-error: true   # ← ignored by Gitea
+    steps:
+      - run: git diff ...    # ← if this fails, job = failure
+        # job-level flag does not help
+
+# RIGHT — step-level flag prevents step from failing
+jobs:
+  my-job:
+    steps:
+      - run: git diff ... || true  # ← step exits 0
+        continue-on-error: true     # ← belt and suspenders
+```

+## `workflow_dispatch.inputs` not supported
+
+Gitea 1.22.6 parser rejects `workflow_dispatch.inputs`. Drop from all workflow
+YAML files ported from GitHub Actions. Manual triggers should use
+`workflow_dispatch` without `inputs:`.
+
+**Reference**: `feedback_gitea_workflow_dispatch_inputs_unsupported`
+
+---
+
+## `merge_group` not supported
+
+Gitea has no merge queue concept. Drop `merge_group:` triggers from all
+workflow YAML files.
+
+---
+
+## `environment:` blocks not supported
+
+Gitea has no environments concept. Drop `environment:` from all workflow YAML
+files. Secrets and variables are repo-level.

+
+## Gitea combined status reports `failure` when all contexts are `null`
+
+### Finding
+
+When ALL individual status contexts for a commit have `state: null` (no runner
+has reported yet), Gitea reports the combined commit status as `failure`. This
+is a Gitea Actions bug — it conflates "no status reported yet" with "failed".
+
+### Impact
+
+- The `main-red-watchdog` workflow opens a `[main-red]` issue for every
+  scheduled workflow run where the combined state is `failure` — even when
+  the failure is entirely due to Gitea's combined-status bug.
+- This causes spurious `[main-red]` issues that waste SRE time investigating
+  non-existent failures.
+- **This is especially confusing for `schedule:`-only workflows** (canary,
+  sweep jobs, synth-E2E): Gitea attributes their scheduled runs to `main`'s
+  HEAD commit, so if a scheduled run fires while all contexts are still
+  `state: null`, the watchdog opens a `[main-red]` issue on the latest main
+  commit even though that commit itself is perfectly fine.
+
+### How to diagnose
+
+Always check the **individual context `state` fields**, not the combined
+`state`/`combined_state`. In the `/repos/{org}/{repo}/commits/{sha}/statuses`
+API response, look for `"state": null` on every entry — if all are null, the
+combined `failure` is Gitea's bug, not a real CI failure.
+
+```json
+{
+  "combined_state": "failure",   // ← Gitea bug when all are null
+  "contexts": [
+    { "context": "CI / Lint", "state": null },  // still running
+    { "context": "CI / Test", "state": null }   // still running
+  ]
+}
+```
+
+### Affected workflows
+
+All workflows, but especially `schedule:`-only workflows that run on `main`.
+The main-red-watchdog (`.gitea/workflows/main-red-watchdog.yml`) is the
+primary consumer of combined status and is affected.

+//
+// Background (#2872 + post-2026-05-06 follow-up):
+//   - Migration 20260506000000_workspaces_unique_parent_name added a
+//     partial UNIQUE index on (COALESCE(parent_id, sentinel), name)
+//     WHERE status != 'removed'. It exists to close the TOCTOU race in
+//     /org/import that previously let two concurrent POSTs both INSERT
+//     the same (parent_id, name) row.
+//   - /org/import handles the constraint via `ON CONFLICT DO NOTHING`
+//     + idempotent re-select (handlers/org_import.go).
+//   - The Canvas Create handler (handlers/workspace.go) did NOT — a
+//     duplicate POST returned an opaque HTTP 500 with the raw pq error
+//     in the server log. Repro path: user clicks a template card twice
+//     in canvas before the first response paints.
+//
+// Resolution: auto-suffix the user-typed name on collision. The
+// uniqueness constraint required for #2872 stays in place; only the
+// Canvas Create path's reaction to it changes. Names become a
+// free-form display label that the platform disambiguates; row
+// identity is carried by the workspace id (UUID).
+//
+// Suffix shape: " (2)", " (3)", … up to N=maxNameSuffix. Chosen over
+// numeric "-2" / "_2" because the parenthesised form is the standard
+// disambiguation pattern users already expect from Finder / Explorer
+// / Google Docs / file managers. Stays under the 255-char name cap

+// Why this is NOT a sqlmock test
+// ------------------------------
+// sqlmock CANNOT verify the actual partial-unique-index
+// behaviour. The unit tests in workspace_create_name_test.go pin
+// the helper's retry contract under a fake driver error, but only
+// a real Postgres can confirm:
+//
+//   - The migration 20260506000000 actually created the index.
+//   - lib/pq emits SQLSTATE 23505 with Constraint =
+//     "workspaces_parent_name_uniq" (not a synonym, not the message
+//     fallback).
+//   - The COALESCE(parent_id, sentinel) target collapses NULL
+//     parent_ids so two root-level workspaces with the same name
+//     collide as the migration intends.
+//   - The WHERE status != 'removed' partial filter exempts
+//     tombstoned rows from blocking re-use.
+//
+// Per feedback_mandatory_local_e2e_before_ship: ship-mode requires
+// the helper to be exercised against a real Postgres before the PR
+// merges.

+
+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.
