+# Invoked from `.gitea/workflows/sop-tier-refire.yml` when a repo
+# MEMBER/OWNER/COLLABORATOR comments `/refire-tier-check` on a PR.

+#
+# 1. Resolve PR head SHA + author from PR_NUMBER.

+#    composition gate logic, not a watered-down approving-count check.
+# 4. POST the resulting status (success on exit 0, failure on non-zero)
+#    to `/repos/.../statuses/{HEAD_SHA}` with context
+#    "sop-tier-check / tier-check (pull_request)" — the same context name

+#
+# 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.

+/**
+ * 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.

+# 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.

+## 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

+
+## 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):

+//     partial UNIQUE index on (COALESCE(parent_id, sentinel), name)

+//     /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

+// 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.
