## Launch prompt

```
Implement SLICE-1 (off-host GCS bucket + write access) of the Gitea-forge backup feature, per specs/gitea-forge-backups.md §7.2 (engineering#30). Operator chose: do the no-downtime prep now (create the backup GCS bucket + IAM + a dedicated gcloud config for project wiggleverse) and DEFER the disruptive VM stop/scope-change to a coordinated window (session 0009 was live).
```

## Plan

> Anchor: design specs/gitea-forge-backups.md (graduated; R2a) — engineering#30.

Scope (operator chose "prep now, defer VM stop"): the no-downtime portion of
**SLICE-1** — create the off-host backup GCS bucket (versioned, lifecycle,
uniform access, public-access enforced), grant the VM SA `objectCreator`, create
a dedicated `gitea` gcloud config, document it. Defer the disruptive VM-scope
change (stop/set-scopes/start) to a coordinated maintenance window because
session 0009 was live.

Worktree: isolated in `worktree-session-0011` (live concurrent session 0009).

## Pre-state

- `main` clean and in sync. Spec `specs/gitea-forge-backups.md` graduated in
  session 0010.
- `gitea` VM (project `wiggleverse`, RUNNING) on the default compute SA with scope
  **`devstorage.read_only`** — can read GCS, cannot write.
- No dedicated gcloud config for the forge project (§8.4 gap).
- Session 0009 still live on this app throughout.

## Session arc (turn by turn)

1. Operator asked to "do the VM service-account scope fix now." Surfaced that the
   fix needs a VM stop/start → `git.wiggleverse.org` downtime, which would break
   the **live session 0009**. Asked how to proceed; operator chose **"prep now,
   defer VM stop."**
2. Opened this planning-and-executing session (claimed 0011), eligibility ELIGIBLE
   (R2a, anchored on the graduated design), isolated in worktree
   `worktree-session-0011`.
3. Created the dedicated **`gitea` gcloud config** (project `wiggleverse`,
   `--no-activate`). **Slip + immediate fix:** accidentally ran
   `gcloud config configurations activate gitea`, which rewrote the shared
   on-disk active pointer (§8.4 says never to); reverted by re-activating
   `benstull-infra`. Thereafter used per-process `CLOUDSDK_ACTIVE_CONFIG_NAME=gitea`.
4. Created **`gs://wiggleverse-gitea-backups`** (project `wiggleverse`,
   `us-central1`): uniform bucket-level access, public-access-prevention enforced,
   versioning on, lifecycle (30d delete + 7d noncurrent) from a committed
   `infra/gitea-backup-bucket-lifecycle.json`. Granted the VM SA
   `roles/storage.objectCreator` (create-only). Verified all settings.
5. Documented the bucket + IAM + the **PENDING** VM-scope change in
   `infra/deploy-gitea-on-gcp.md`. Committed; PR **#33** → merged to `main`.

## Cut state (final)

- **On `main`** (merge `4d72bb1`, PR #33): `infra/gitea-backup-bucket-lifecycle.json`
  + the "Backups (off-host forge recovery)" section in `infra/deploy-gitea-on-gcp.md`.
- **Cloud (project `wiggleverse`):** bucket `gs://wiggleverse-gitea-backups`
  configured as above; VM SA has `objectCreator`; dedicated `gitea` gcloud config
  exists (inactive; on-disk active pointer left as `benstull-infra`).
- **Not shipped via an app pipeline** — bootstrap-infra provisioning (the bucket is
  the deploy); no localhost→PPE→prod stage applies, no flotilla.
- Worktree + local/remote review branch removed; `main` clean.

## Deferred decisions

- **gcloud active-pointer slip (fixed in-session).** Briefly activated the `gitea`
  config, rewriting the shared active pointer (§8.4 violation); caught and reverted
  to `benstull-infra`. No lasting effect. Flagging the foot-gun: `gcloud config set`
  with `CLOUDSDK_ACTIVE_CONFIG_NAME=<cfg>` does NOT require activating.
- **Retention window = 30 days** (default; +7d noncurrent). Not an operator-set
  number — chosen as a sensible default for a small forge at 3 snapshots/day (~90
  recovery points). Tunable via the committed lifecycle file; revisit if cost or
  recovery-depth needs change.
- **VM-scope change deferred to a maintenance window** (operator's explicit choice,
  because session 0009 was live). The exact stop→set-service-account→start commands
  are in `infra/deploy-gitea-on-gcp.md`. This is the next `/goal`.
- **Worktree isolation** for the live-0009 concurrency (skill Step 6b); 0009's scope
  not inspected.

## Operator plate (what's left)

- **The one operator-coordinated action ahead:** schedule the brief
  `git.wiggleverse.org` maintenance window to raise the VM SA scope to
  `cloud-platform` — until then the scheduled backup (SLICE-2) cannot upload.
- Nothing parked beyond the next `/goal`; SLICES 2–5 are in the spec §7.2 and
  tracked under issue #30.

## Next-session prompt

```
/goal 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), then finish SLICE-1 (verify the VM can write to gs://wiggleverse-gitea-backups) and build SLICE-2 scheduled dump+upload, per specs/gitea-forge-backups.md §7.2 (engineering#30)
```
