## Plan
> Anchor: design specs/gitea-forge-backups.md (engineering#30) — SLICE-3
> (Retention / rotation proven → guards BO-1 durability). Eligibility: ELIGIBLE (R2a).
SLICE-3 proves T-4 (retention) on the scratch bucket
`gs://wiggleverse-gitea-backups-scratch` (kept from SLICE-2): an over-age object
is purged by the lifecycle policy, in-window objects and prior (noncurrent)
versions survive (INV-5). Approach: mirror the prod bucket's config on scratch
(versioning + the committed lifecycle JSON) plus a test rule keyed on
`daysSinceCustomTime` (the controllable analogue of `age`, which cannot be
back-dated); seed over-age / in-window / versioned-pair objects; wait for the
GCS lifecycle pass (≤ 24–48 h) with a deterministic verify script; then update
the infra doc + spec changelog and ship via PR. No prod mutation — prod's
lifecycle/versioning were applied in SLICE-1 and are drift-checked read-only.
## Execution log (checkpoint 2026-06-10T22:00 PST)
- Branch `worktree-gitea-backups-slice-3` off `origin/main` (in the
slice-2 worktree, adopted — two concurrent sessions in flight: 0009, 0017).
- Plan written: `docs/superpowers/plans/2026-06-10-gitea-backups-slice-3.md`.
- Tasks 1–4 done: scratch bucket versioning enabled + T-4 lifecycle applied
(committed `infra/gitea-backup/t4-scratch-lifecycle.json`); prod bucket
drift-checked clean (lifecycle == committed JSON, versioning on);
`infra/gitea-backup/t4-retention-check.sh` (seed/verify) committed; fixtures
seeded (overage customTime 2026-04-27; inwindow; versioned pair) and verify
exercised its PENDING path (exit 1). Branch pushed.
- Now waiting on the GCS lifecycle pass (≤ ~48 h; expected ≤ ~24 h), polling
hourly via verify.

- **T-4 over-age trigger uses `daysSinceCustomTime: 30`, not prod's `age: 30`**
— `age` cannot be back-dated, so executing the real rule means 30 days of
wall clock. Same threshold, same lifecycle Delete engine; substitution
documented in the infra doc. Confidence: high, but it is a fidelity call the
operator may want to revisit.
- **The 7-day noncurrent purge is config-verified, not execution-verified** —
executing it adds ≥ 7 days for the same Delete machinery already exercised by
the over-age purge. Versioning *protection* (prior version survives) is
execution-verified.
