+# 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)

+"""status-reaper — Option B compensating-status POST for Gitea 1.22.6's

+
+Tracking: this PR (workflow + script + tests + audit issue). Sibling
+bots: internal#327 (publish-runtime-bot), internal#328 (mc-drift-bot).
+Upstream RFC: internal#80. Persona provisioned by sub-agent aefaac1b
+(2026-05-11 21:39Z; Gitea uid 94, scope=write:repository).
+
+What this script does, per `.gitea/workflows/status-reaper.yml` invocation:
+
+  1. Walk `.gitea/workflows/*.yml`. For each file, build the workflow_id
+     using this resolution (per hongming-pc 22:08Z review):
+       - If YAML has top-level `name:` → use that.
+       - Else → use filename stem (basename minus `.yml`).
+     Fail-LOUD on:
+       - Two workflows resolving to the SAME identifier (collision).
+       - Any identifier containing `/` (it would break context parsing
+         downstream — Gitea uses ` / ` as the workflow/job separator).
+     Classify each by whether `on:` contains a `push:` trigger.
+
+  2. List the last N (=10) commits on WATCH_BRANCH via
+     GET /repos/{o}/{r}/commits?sha={branch}&limit={N}. rev2 sweeps
+     N commits per tick instead of HEAD only — schedule workflows
+     post `failure` to whatever SHA was HEAD when they COMPLETED, so
+     by the next */5 tick main has often moved forward and the red
+     gets stranded on a stale commit (Phase 1+2 evidence: rev1 saw
+     `compensated:0` every tick across ~6 cycles).
+
+  3. For EACH SHA in the list:
+       - GET combined commit status. Per-SHA error isolation
+         (refinement #7): if this call raises ApiError or any 5xx,
+         LOG `::warning::` + continue to the next SHA. Different from
+         the single-HEAD pre-rev2 path where fail-loud was correct;
+         the sweep is best-effort across historical commits, so one
+         transient blip on a stale SHA must not strand reds on the
+         OTHER stale SHAs.
+       - If combined.state == "success": skip — cost optimization
+         (refinement #2), common case (most commits are green).
+       - Otherwise iterate per-context entries. For each entry where:
+           state == "failure" AND context.endswith(" (push)")
+         Parse context as `<workflow_name> / <job_name> (push)`.
+         Look up workflow_name in the trigger map:
+           - missing → log ::notice:: and skip (conservative).
+           - has_push_trigger=True → preserve (real defect signal).
+           - has_push_trigger=False → POST a compensating
+             `state=success` status to /statuses/{sha} with the same
+             context (Gitea de-dups by context) and a description
+             documenting the workaround + this script's path.
+
+  4. Exit 0. Re-running is idempotent — Gitea's commit-status table
+     stores the LATEST state-per-context, so the success POST sticks
+     even if another tick happens before the runner finishes.
+
+What it does NOT do:
+  - Touch any context NOT ending in ` (push)`. The required-checks on
+    main (verified 2026-05-11) all have ` (pull_request)` suffixes;
+    they CANNOT be reached by this code path.
+  - Compensate `error`/`pending` states. Only `failure` — the only one
+    Gitea emits for the hardcoded-suffix bug.
+  - Write to non-default branches. WATCH_BRANCH is sourced from
+    `github.event.repository.default_branch` in the workflow.
+  - Mutate workflows or runs. The Actions UI still shows the
+    underlying schedule-triggered run as failed; this script edits
+    the commit-status surface only.
+
+Halt conditions (script-level — orchestrator-level halts are in the
+workflow comments):
+  - PyYAML missing → fail-loud at import (no fallback parse).
+  - Workflow `name:` collision → exit 1 with ::error:: message.
+  - Workflow `name:` containing `/` → exit 1 with ::error:: message.
+  - Ambiguous `on:` shape (e.g. neither str/list/dict) → treat as
+    "has_push_trigger=True" and log ::notice:: (preserve, never
+    compensate the unknown).
+  - api() non-2xx → raise ApiError, fail the workflow run loudly so
+    a subsequent tick retries (per
+    `feedback_api_helper_must_raise_not_return_dict`).

+# 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.

+# 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.

+# Tracking: molecule-core#? (this PR), internal#327 (sibling publish-runtime-bot),

+# bots already deployed under the same per-persona-identity contract
+# (`feedback_per_agent_gitea_identity_default`).
+#
+# Root cause:
+#   Gitea 1.22.6 emits commit-status context as
+#     `<workflow_name> / <job_name> (push)`
+#   for ANY workflow run on the default branch's HEAD commit, REGARDLESS
+#   of the trigger event. Schedule- and workflow_dispatch-triggered runs
+#   on `main` therefore appear as `(push)` failures on the latest main
+#   commit, painting main red via a fake-push status. Verified on runs
+#   14525 + 14526 via Phase 1 evidence (3 sub-agents). No upstream fix
+#   in 1.23-1.26.1 (sibling a6f20db1 research).
+#
+# Why a cron-driven reaper, not workflow_run:
+#   Gitea 1.22.6 does NOT support `on: workflow_run` (verified via
+#   modules/actions/workflows.go enumeration; sister a6f20db1). The
+#   only event-shaped option that fires is cron. 5min is chosen to
+#   sit BETWEEN ci-required-drift (`:17` hourly) and main-red-watchdog
+#   (`:05` hourly) so the reaper sweeps red before the watchdog files
+#   a `[main-red]` issue (would-be false-positive).
+#
+# What the reaper does each tick:
+#   1. Parse `.gitea/workflows/*.yml`, classify each by whether `on:`
+#      contains a `push:` trigger (see script for workflow_id resolution
+#      including `name:` collision and `/`-in-name fail-loud lints).
+#   2. GET combined status for main HEAD.
+#   3. For each `failure` status whose context ends ` (push)`:
+#      - if workflow has push trigger: PRESERVE (real defect signal).
+#      - if workflow has no push trigger: POST a compensating
+#        `state=success` with the same context and a description that
+#        documents the workaround.
+#
+# What it does NOT do:
+#   - Mutate non-`(push)`-suffix statuses (e.g. `(pull_request)` from
+#     branch_protections required-checks — verified safe 2026-05-11).
+#   - Auto-revert. Same reasoning as main-red-watchdog.
+#   - Cancel runs. The runs themselves stay visible in Actions UI; the
+#     fix is at the commit-status surface only.
+#
+# Removal path: drop this workflow when Gitea ≥ 1.24 ships with a

+ * Tests for EmptyState — the first-deploy card shown on an empty canvas.
+ *
+ * Coverage:
+ *   - Loading state: Spinner + "Loading templates..."
+ *   - Template grid renders with name, description, tier badge, skill count
+ *   - Template button click calls deploy(template)
+ *   - "Deploying..." text shown for the in-flight template
+ *   - All deploy buttons disabled while any deploy is in progress
+ *   - "Create blank" renders and is clickable
+ *   - "Create blank" POSTs /workspaces and shows "Creating..." while pending
+ *   - handleDeployed selects node and sets panel tab after 500ms delay
+ *   - Error display: role="alert" for blankError and deploy error
+ *   - Network error falls back to empty templates array
+ *   - OrgTemplatesSection is rendered
+ *   - Tips section is rendered

+ * Tests for ExternalConnectModal — the modal surfaced after creating a
+ * runtime="external" workspace. Surfaces workspace_auth_token + ready-to-paste
+ * snippets so the operator can configure their off-host agent.
+ *
+ * Coverage:
+ *   - Renders nothing when info=null
+ *   - Opens dialog when info is provided
+ *   - Default tab: "Universal MCP" when universal_mcp_snippet present, else "Python SDK"
+ *   - Tab switching between all available tabs
+ *   - Snippets show with auth_token replacing placeholders
+ *   - Copy button: calls clipboard API, shows "Copied!", clears after 1.5s
+ *   - Copy failure: shows fallback textarea
+ *   - "I've saved it — close" calls onClose
+ *   - Security warning: one-time token display
+ *   - Fields tab shows raw values
+ *   - Tabs hidden when their snippet is absent
+ *
+ * Fake timers: applied per-describe to avoid mixing with waitFor. Tests that
+ * use waitFor (which needs real timers) run without fake timers. Tests that
+ * verify setTimeout behavior use vi.useFakeTimers() + act(vi.advanceTimersByTime).

+ *
+ * Coverage:

+ *   - Click transitions to confirming state: "Delete N workspace(s)?" + Yes/No
+ *   - No-click dismisses back to idle
+ *   - Yes-click fires API DELETE + optimistic lock (beginDelete)
+ *   - Success: shows success toast, removes subtree from store
+ *   - Failure: shows error toast, unlocks (endDelete), stays on confirm screen
+ *   - aria-label reflects rootName
+ *
+ * Uses globalThis mock sharing to survive vitest hoisting of vi.mock factories.

+/**
+ * Tests for FileEditor — the text editor pane in the Files tab.
+ *
+ * FileEditor is fully prop-driven (no stores, no API calls).
+ * All props passed explicitly per-test to avoid defaultProps + vi.fn()
+ * module-scope issues in React 19.
+ *
+ * Coverage:
+ *   - Empty state: no selected file → placeholder UI
+ *   - File header: filename and icon rendered
+ *   - Modified badge: shown when editContent ≠ fileContent
+ *   - Modified badge: hidden when content is clean
+ *   - Download button calls onDownload
+ *   - Save button disabled when not dirty
+ *   - Save button disabled when saving
+ *   - Save button shows "Saving..." text when saving
+ *   - Save button hidden when root ≠ /configs
+ *   - Save button visible when root === /configs
+ *   - Save button enabled when dirty and not saving
+ *   - Cmd+S triggers onSave
+ *   - Tab key inserts two spaces
+ *   - Textarea is readOnly when root ≠ /configs
+ *   - Textarea is writable when root === /configs
+ *   - Loading state shows "Loading..." text
+ *   - onChange updates editContent
+ *   - Success message displayed when success prop is set

+ *   - Error states (channels fail / adapters fail)
+ *   - Channel list rendering (single + multiple)
+ *   - Toggle channel on/off
+ *   - Delete channel via ConfirmDialog
+ *   - Test channel connection
+ *   - Connect form open/close
+ *   - Platform selector and schema switching
+ *   - Discover Chats (Telegram only)
+ *   - Required field validation
+ *   - Successful channel creation
+ *   - Auto-refresh every 15s
+ *   - SchemaField (password, textarea, placeholders, help text)
+ *   - Legacy fallback when no config_schema

+ * Tests for DetailsTab — workspace detail panel in the side panel.
+ *
+ * Coverage:
+ *   - View mode: renders workspace info (name, role, tier, status, url, parent)
+ *   - View mode: renders T1/T2/T3/T4 tier display
+ *   - View mode: shows active tasks count
+ *   - Edit mode: opens when Edit is clicked
+ *   - Edit mode: pre-fills name/role/tier from current data
+ *   - Edit mode: changes propagate to form state
+ *   - Save: PATCH /workspaces/:id with correct payload
+ *   - Save success: calls updateNodeData + exits edit mode
+ *   - Save error: shows error message
+ *   - Cancel: restores original name/role/tier + exits edit mode
+ *   - Restart button: visible for offline/failed/degraded workspaces
+ *   - Restart button: hidden for online/provisioning workspaces
+ *   - Restart: POST /workspaces/:id/restart + sets status to provisioning
+ *   - Restart error: shows error message
+ *   - Error section: shown for failed/degraded workspaces
+ *   - Error section: shows lastSampleError in <pre>
+ *   - Error section: shows 'No error detail recorded' when none
+ *   - Console button: opens ConsoleModal
+ *   - Peers: skipped when workspace is not online/degraded
+ *   - Peers: loaded from GET /registry/:id/peers when online
+ *   - Peers: shown with StatusDot and name
+ *   - Peers: click navigates to peer node
+ *   - Peers error: shown when load fails
+ *   - Delete confirmation: two-step (click → confirm)
+ *   - Delete: DEL /workspaces/:id?confirm=true + removeSubtree + selectNode(null)
+ *   - Delete error: shown when DEL fails
+ *   - ConsoleModal: mounted and rendered
+ *   - Tier change via select

+ *
+ * Coverage:
+ *   - Loading state (no events yet)
+ *   - Empty state ("No events yet")
+ *   - Event list renders with event_type color
+ *   - Expand/collapse row
+ *   - Refresh button triggers reload
+ *   - Error state surfaces API failure message
+ *   - Auto-refresh every 10s (fake timers)
+ *   - formatTime relative timestamps
+ *
+ * Fake timers are ONLY used in the auto-refresh describe block where we need
+ * to control the clock. All other tests use real timers so Promises resolve
+ * naturally without fighting the fake-timer queue.

+ * Tests for MemoryTab — the workspace KV memory tab.
+ *
+ * Coverage:
+ *   - Loading state (pending GET)
+ *   - 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.

+ *   - Schedule list rendering (single + multiple)
+ *   - Status dot color (error/ok/idle)
+ *   - Toggle enable/disable via status dot
+ *   - Delete via ConfirmDialog
+ *   - Run Now button triggers POST + POST
+ *   - Create schedule form open/close
+ *   - Edit schedule form pre-fills values
+ *   - 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

+ * Tests for form-inputs — shared form components for the Config tab.
+ *
+ * TextInput coverage:
+ *   - Renders label and input
+ *   - aria-label matches label text
+ *   - onChange called with new value
+ *   - placeholder text rendered
+ *   - mono class applied when mono=true
+ *
+ * NumberInput coverage:
+ *   - Renders label and number input
+ *   - aria-label matches label text
+ *   - onChange called with parsed integer
+ *   - min/max attributes applied
+ *   - Parses empty input as 0
+ *
+ * Toggle coverage:
+ *   - Renders checkbox with label
+ *   - Checkbox checked state reflects checked prop
+ *   - onChange called with boolean
+ *
+ * TagList coverage:
+ *   - Renders existing tags with remove button
+ *   - Remove button has aria-label with tag name
+ *   - Remove button calls onChange without that tag
+ *   - Enter key with non-empty input adds tag and clears input
+ *   - Enter with empty input does not add tag
+ *   - Placeholder text rendered
+ *
+ * Section coverage:
+ *   - defaultOpen=true renders children on mount
+ *   - defaultOpen=false hides children on mount
+ *   - Clicking header toggles children visibility
+ *   - Toggle icon changes between ▾ and ▸
+ *   - Header has accessible button

+# 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.

+"""Tests for `.gitea/scripts/status-reaper.py` — Option B compensating
+status POST for Gitea 1.22.6's hardcoded `(push)` suffix bug.
+
+Coverage (per hongming-pc 22:08Z review + brief):
+  1. test_workflow_with_name_field
+  2. test_workflow_without_name_field (filename stem fallback)
+  3. test_workflow_name_collision_fails_loud
+  4. test_workflow_name_with_slash_fails_loud
+  5. test_has_push_trigger_true (dict shape, list shape, str shape)
+  6. test_has_push_trigger_false (schedule-only, dispatch-only,
+     pull_request-only, workflow_run-only)
+  7. test_publish_workspace_server_image_preserved (explicit case)
+  8. test_compensating_post_payload (POST body shape verification)
+
+Plus regression coverage:
+  - parse_push_context strictness (only ` (push)` suffix with ` / `
+    separator triggers compensation).
+  - Class-O detection via end-to-end reap() with a stubbed api().
+  - ApiError propagation on non-2xx (mirror of main-red-watchdog's
+    `feedback_api_helper_must_raise_not_return_dict` test).
+  - Unknown-workflow conservatism: ::notice:: + skip, never POST.
+  - Non-`(push)`-suffix contexts (the `(pull_request)` required-checks
+    on main) are NEVER touched — verified safe 2026-05-11.
+
+Hostile self-review proof:
+  - test_required_check_pull_request_suffix_never_touched exercises
+    the safety contract: a pre-fix that compensated any failing
+    context would mask the Secret scan required-check. Verified by
+    stashing the `endswith(PUSH_SUFFIX)` guard and re-running: test
+    FAILS as required.
+  - test_workflow_name_collision_fails_loud asserts exit code 1; a
+    pre-fix that "first write wins" would silently misclassify a
+    renamed workflow.
