## Launch prompt

```
Resume stored goal (/goal next): gitea-forge-backups SLICE-5 — off-VM freshness/failure alert (Cloud Scheduler → Cloud Run/Function reading bucket object/marker age; T-3 green; finalize RB-3/RB-4), AND fix the broken marker-refresh path in gitea-backup.sh (markers/last-success.json ~24h stale while dumps land), per specs/gitea-forge-backups.md §7.2 (engineering#30)

```

## Plan

> Anchor: design `specs/gitea-forge-backups.md` (graduated Solution Design, engineering#30) — ELIGIBLE (R2a).
> Goal (`/goal next`): gitea-forge-backups SLICE-5 freshness alert + fix the broken marker-refresh path.

**Diagnosis (marker bug):** `markers/last-success.json` froze at the FIRST live run
(2026-06-11T04:46Z) while 4-hourly dumps keep landing. Root cause: the VM SA holds
only `roles/storage.objectCreator` (`storage.objects.create`), which **cannot
overwrite an existing live object**. Dumps use unique names → fresh create → OK.
The marker uses a FIXED name → every run after the first is an overwrite → 403 →
marker never refreshes; the job exits non-zero *after* the dump uploaded. Fix must
NOT grant `objects.delete` (would let a compromised VM destroy backups — breaks
§6.6/R-4 least-privilege). Correct fix = unique-named per-run markers (always a
create), freshness keyed off newest-object age.

**Increment 1 — Marker-refresh fix (PR A):**
1. `infra/gitea-backup/gitea-backup.sh`: write the marker under a per-run name
   (`markers/last-success-<ts>.json`) — always a create; also keep richer fields.
2. Spec §6.3/§6.4 data-model wording (marker key is per-run; newest-object age is
   the primary freshness signal) + changelog bump.
3. DOC-2 (`infra/deploy-gitea-on-gcp.md`) backups section update.
4. Re-install on the live forge VM; run the service manually; verify a fresh marker
   lands and a 2nd run refreshes (the create-not-overwrite proof).

**Increment 2 — SLICE-5 freshness checker (PR B):**
1. Checker (Cloud Run job/Function, project `wiggleverse`, config `gitea`): list
   newest `gitea-dump-*.zip`, compute age, emit signal.
2. Alert delivery = Cloud Monitoring-native (no new secrets): custom metric +
   alert policy → email notification channel; off-VM dead-man's-switch.
3. Provision by hand (bootstrap infra, D-6 — NOT flotilla): Scheduler + checker +
   notification channel + alert policy.
4. T-3 green against scratch bucket (stale → fires; fresh → quiet) before live.
5. Finalize RB-3/RB-4 in `infra/backup-restore-gitea.md`; DOC-2 update; spec
   SLICE-5 done + changelog.

## Deferred decisions

_Autonomous-mode low-confidence calls the driver made and would have
liked operator input on. Appended as the session runs; surfaced at
finalize. Empty if none._

- **Marker fix shape (medium-high confidence):** chose unique-named per-run markers
  over (a) granting `objects.delete` — rejected, breaks the §6.6/R-4 "VM can create
  but not delete" security invariant — or (b) dropping the marker entirely and
  keying only off newest-dump age. Per-run markers keep the spec's TEL-1 marker
  artifact refreshing within least-privilege. Small spec data-model wording update
  follows; flagging in case the operator prefers a fixed canonical pointer.
