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

## Pre-state

- engineering `main` at `721538d`, clean, == `origin/main`; no open PRs.
- SLICE-1 prep done (session 0011, PR #33): bucket `gs://wiggleverse-gitea-backups`
  (versioned, lifecycle), VM SA `objectCreator`, dedicated `gitea` gcloud config.
- BLOCKER: VM scope `devstorage.read_only` → cannot upload via ADC. Tracked as
  issue #34 (P0, task).
- Concurrent live session: SESSION-0009 (started 09:40, own worktree
  `engineering-session-0009`) → this session isolated per §5.4 / init Step 6b.

## Turn-by-turn arc

1. **Init.** Classified `/goal` prompt as planning-and-executing; claimed
   SESSION-0016 (atomic push, advisory 0016 held); anchor eligibility ELIGIBLE
   (R2a — graduated design `specs/gitea-forge-backups.md`); baseline clean;
   entered native worktree `gitea-vm-scope-window` (branch
   `worktree-gitea-vm-scope-window`).
2. **Plan seeded + pre-window checkpoint** published to session-history
   (deliberately before stopping the VM that hosts it).
3. **Auth detour (wrong turn, recovered).** The `gitea` gcloud config's CLI
   token had expired; interactive `gcloud auth login` impossible
   non-interactively. Tried alternate account — also expired. Asked operator to
   reauth; Stop-hook pushed for progress, so: started a background poller for
   CLI auth AND discovered ADC was still valid → ran the read-only pre-check
   via the Compute REST API (project explicit in URL; §8.4 satisfied, no config
   pointer touched). Pre-state recorded: RUNNING, default-SA, legacy scopes
   incl. `devstorage.read_only`. Operator's login then landed (poller exit 0).
4. **The window** (documented CLI commands, `CLOUDSDK_ACTIVE_CONFIG_NAME=gitea`):
   `stop` (≈2 min) → `set-service-account --scopes=cloud-platform` → `start`
   (operator executed the start command directly, interrupting the agent's
   identical call). ~3 min forge downtime total.
5. **Verification.** Post-state RUNNING, same SA, scopes = `cloud-platform`
   only. Forge: HTTPS 200 on https://git.wiggleverse.org/ within ~20 s; SSH
   :2222 `git ls-remote` OK. Metadata server on-VM confirms `cloud-platform`.
6. **Write test (SLICE-1 proof).** `gsutil cp` from the VM **403s** — its
   destination-existence check needs `storage.objects.list`, which the
   create-only `objectCreator` IAM denies (misleading error; upload itself is
   allowed). Pure-create JSON-API `objects.insert` from the VM returned
   **HTTP 200** (`maintenance/scope-fix-write-test.txt`). Verified from laptop,
   then deleted with operator credentials (VM correctly cannot delete).
7. **DOC-2.** Runbook `infra/deploy-gitea-on-gcp.md` updated: PENDING box →
   build-state record (scope raised 2026-06-10, session 0016); §1 OAuth warning
   and cert-rotation note brought current (Secret Manager self-fetch / Path A
   now possible); SLICE-2 note on the gsutil-vs-create-only-IAM gotcha.
   Commit `13807f2` → PR #41 → merged to `main` (`69051a2`).
8. **Closeout.** Issue #34 commented with the outcome and closed. Memory
   (`project_gitea_forge_backups.md` + MEMORY.md index) updated: SLICE-1
   COMPLETE, next = SLICE-2. Operator asked whether SLICE-2 was also done —
   answered plainly: no, only unblocked.
9. **Finalize.** Worktree torn down (branch merged; commit confirmed on
   `origin/main` before discard), canonical `main` fast-forwarded to `69051a2`,
   merged remote branch deleted, transcript finalized and published.

## Cut state

- **SLICE-1 of engineering#30: COMPLETE.** VM scope `cloud-platform`; bucket
  writable from the VM via ADC (proven); forge healthy; issue #34 closed;
  runbook current (PR #41 merged).
- **No automated backups exist yet** — SLICE-2 (8-hour `gitea dump` + upload
  timer) is unblocked but unbuilt. The forge still has zero scheduled backups.
- No plan artifact to archive (infra gesture; procedure was already canonical
  in the runbook — the `## Plan` block above is the session plan record).
- Pipeline (§9) status: hand-provisioned bootstrap infra + docs PR — no
  deployable app stage applies; the scratch-Gitea restore drill (SLICE-4) is
  the designated PPE stand-in for this capability.

## 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.

## Operator plate

- Nothing pending from this session. (SESSION-0009 remains in flight,
  unrelated — its own worktree and transcript.)

## Next-session prompt

```
/goal Build gitea-forge-backups SLICE-2 — scheduled gitea dump every 8h on the VM uploading to gs://wiggleverse-gitea-backups (use a pure-create upload path, not gsutil cp), per specs/gitea-forge-backups.md §7.2 (engineering#30)
```
