## Launch prompt

```
Build gitea-forge-backups SLICE-2 — scheduled gitea dump every 4 hours (operator override of the spec's 8h) on the VM uploading to gs://wiggleverse-gitea-backups (pure-create upload path, not gsutil cp), per specs/gitea-forge-backups.md §7.2 (engineering#30).

```

## Plan

> Anchor: design specs/gitea-forge-backups.md (engineering#30, graduated; SLICE-2, §7.2)

Implementation plan: `plans/2026-06-10-gitea-backups-slice-2.md` (authored this
session). Headline: `infra/gitea-backup/` gains `gitea-backup.sh` +
`gitea-backup.{service,timer}` (every **4 h** — operator override of Q2's 8 h,
this session); script runs `gitea dump` read-only in the container, `unzip -t`
+ sha256, pure-create JSON-API upload (objectCreator can't `objects.list`, so
no gsutil), success marker `markers/last-success.json`, staging cleanup, one
retry. Gate: T-1 against scratch gitea container + scratch bucket
(`wiggleverse-gitea-backups-scratch`) BEFORE enabling live (spec §6.8). Then
enable timer on the forge, first live run verified, docs (runbook build state,
spec interval amendment) → PR → merge.

Session runs isolated in worktree `gitea-backups-slice-2` (live concurrent
SESSION-0009 in flight).

## Execution record (checkpoint, ~21:50 PST)

- **Repo artifacts** (PR #42, merged): `infra/gitea-backup/gitea-backup.sh` +
  `gitea-backup.{service,timer}`; spec v0.2.1 (Q2 amended 8h→4h, §6.4/§6.5
  pure-create wording); runbook Backups build-state + operating verbs; plan
  archived in-repo at `plans/2026-06-10-gitea-backups-slice-2.md`.
- **Scratch gate (T-1, spec §6.8)**: scratch bucket
  `gs://wiggleverse-gitea-backups-scratch` (objectCreator for the VM SA; kept
  for SLICE-3's T-4) + throwaway `gitea-scratch` container on the VM (torn
  down after). Two real bugs caught and fixed before live:
  1. staging dir must be created in-container and chowned to `git` (root
     host-mkdir → dump can't write; then /data is root-owned so git can't
     mkdir either);
  2. fresh scratch gitea lacks `/data/git/repositories` (env setup, not a
     script bug).
  T-1 verification independent from the laptop: download, `unzip -t` intact,
  sha256 == marker's (30f85305…), marker JSON complete.
- **Live enable**: units installed, timer enabled. First live run caught bug
  3: `curl --data-binary` buffers the archive in RAM → OOM on the e2-small
  with the real 1.02 GiB dump (scratch was 66 KB — scale fidelity gap in the
  scratch gate, noted). Fixed with streaming `-T`; re-run green:
  `gitea-dump-20260611T044540Z.zip` (1,097,287,374 B) + fresh marker in
  `gs://wiggleverse-gitea-backups`, `Result=success`, next timer firing
  2026-06-11 08:15 UTC on the 4h grid (00/4:15, Persistent).
- SLICE-2 DoD: snapshot landed + verified, timer enabled + idempotent +
  read-only (INV-7); "on schedule" firing observable at 08:15 UTC
  (timer verified armed; first run was the manual trigger per plan).

## Deferred decisions

- Tightened the spec's resolved Q2 (8h) to 4h on the operator's one-line
  instruction ("SLICE-2 but make it every 4 hours") and amended the spec
  (v0.2.1) rather than re-opening Q2 — confident this is what was meant;
  flagging only because it edits a resolved decision row.
- Kept the scratch bucket (`…-backups-scratch`, empty but for one 66 KB test
  object) instead of deleting it — SLICE-3's T-4 retention test reuses it.

_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._
