## Launch prompt

```
Do the gitea VM service-account scope maintenance window (stop → set-service-account --scopes=cloud-platform → start, per infra/deploy-gitea-on-gcp.md Backups box) — unblocks gitea-forge-backups SLICE-1 (engineering#30).

```

## Plan

> Anchor: design specs/gitea-forge-backups.md (engineering#30, graduated; D-3 / §13 Q1: operator approved the maintenance window)

Execute the gitea VM service-account scope maintenance window — the SLICE-1
unblock (spec §7.2 SLICE-1, risk R-1). Procedure is canonical in
`infra/deploy-gitea-on-gcp.md` "Backups" box:

1. Checkpoint-publish this transcript BEFORE the window (session-history lives
   on the VM being stopped).
2. Pre-checks via `CLOUDSDK_ACTIVE_CONFIG_NAME=gitea` (§8.4): VM RUNNING,
   record current SA (`1061347810527-compute@developer.gserviceaccount.com`)
   + scopes (`devstorage.read_only`).
3. `gcloud compute instances stop gitea --zone=us-central1-a`
4. `gcloud compute instances set-service-account gitea --zone=us-central1-a --scopes=cloud-platform`
5. `gcloud compute instances start gitea --zone=us-central1-a`
6. Verify: scopes = cloud-platform, same SA email, forge healthy
   (HTTPS git.wiggleverse.org + SSH :2222), on-VM ADC write-test to
   `gs://wiggleverse-gitea-backups` (proves the unblock; spec D-3).
7. Update the runbook's PENDING box (DOC-2) → branch → PR → merge.

Session runs isolated in worktree `gitea-vm-scope-window` (live concurrent
SESSION-0009 in flight).

## Execution record (checkpoint, ~20:50 PST)

The maintenance window ran and verified clean (spec §7.2 SLICE-1, D-3, §13 Q1):

- **Pre-state** (Compute API): VM RUNNING, SA
  `1061347810527-compute@developer.gserviceaccount.com`, legacy default scopes
  incl. `devstorage.read_only`.
- **Auth detour:** the `gitea` gcloud config's CLI token had expired
  (interactive reauth required). ADC was still valid, so the read-only
  pre-check ran via the Compute REST API (project explicit in URL — §8.4
  satisfied, no config pointer touched). Operator then ran
  `gcloud auth login`; the window itself used the documented CLI commands.
- **Window:** `stop` → `set-service-account --scopes=cloud-platform` →
  `start` (operator executed the start command directly). ~3 min downtime.
- **Post-state:** RUNNING, same SA, scopes = `cloud-platform` only.
- **Forge health:** HTTPS 200 on https://git.wiggleverse.org/ within ~20 s of
  start; SSH :2222 `git ls-remote` OK.
- **Write test (the SLICE-1 proof):** on-VM ADC upload to
  `gs://wiggleverse-gitea-backups/maintenance/scope-fix-write-test.txt` —
  `gsutil cp` 403s (its existence check needs `objects.list`, which
  create-only IAM denies — recorded in the runbook as a SLICE-2 note); pure
  JSON-API `objects.insert` returned HTTP 200. Test object verified then
  deleted from the laptop (operator creds; VM correctly cannot delete).
- **DOC-2:** runbook `infra/deploy-gitea-on-gcp.md` updated (PENDING box →
  build-state record; §1 + cert-rotation notes brought current) — PR #41,
  merged to main.

SLICE-1 is complete; SLICE-2 (scheduled dump + upload timer) is unblocked.

## Deferred decisions

- Deleted the write-test object from the bucket with operator laptop
  credentials rather than leaving it for the 30-day lifecycle — judged
  trivially safe (artifact created seconds earlier by this session), but it
  is technically an irreversible delete.

_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._
