Launch prompt

/goal slice-3
(Resume gitea-forge-backups work — engineering#30, specs/gitea-forge-backups.md. SLICE-1 and SLICE-2 complete; this session plans and executes SLICE-3.)

Pre-state

main clean; SLICE-2 (4-hourly gitea-backup.timer + script) merged by session 0017 the same evening. Sessions 0009 and 0017 in flight (--INPROGRESS) at claim time → this session ran isolated in the operator-pre-created worktree .claude/worktrees/gitea-backups-slice-2, branching worktree-gitea-backups-slice-3 off origin/main.
Scratch bucket gs://wiggleverse-gitea-backups-scratch left from SLICE-2's T-1 gate: no versioning, no lifecycle, 2 leftover test objects.
Prod bucket gs://wiggleverse-gitea-backups: versioning on, committed lifecycle applied (30d delete + 7d noncurrent purge); live 4-hourly ~1.1 GB dumps landing.

Plan

Plan doc: docs/superpowers/plans/2026-06-10-gitea-backups-slice-3.md (merged with the slice; archived to plans/ at finalize). Approach: prove T-4 (spec §6.8) on the scratch bucket — mirror prod config (versioning + both prod rules verbatim) plus a daysSinceCustomTime: 30 test rule, since age cannot be back-dated; seed over-age / in-window / versioned-pair fixtures; poll a deterministic verify script until the asynchronous GCS lifecycle pass runs; record the proof; ship via PR. No prod mutation (drift-check only).

Arc (turn by turn)

Init — session gate → wgl-planning-and-executing; claimed 0018; baseline verified clean; R2/R3 gate: ELIGIBLE (R2a, graduated design).
Tasks 1–4 (evening 06-10) — scratch versioning enabled + T-4 lifecycle applied (infra/gitea-backup/t4-scratch-lifecycle.json); prod drift-checked clean; infra/gitea-backup/t4-retention-check.sh (seed/verify) written; fixtures seeded (overage customTime 2026-04-27; inwindow; versioned pair); verify PENDING path exercised (exit 1); branch pushed; checkpoint published. 30-min monitor armed (48 h deadline).
Operator detour (morning 06-11) — cost question answered with real numbers (~1.1 GB/dump; hourly+7d ≈ $11/mo incl. noncurrent + soft-delete tails); operator decision: keep 30 days / 4 hours (no spec change).
False VIOLATION (~13 h in) — monitor reported "in-window object deleted". Systematic-debugging root cause: expired gcloud token ("Reauthentication failed; cannot prompt during non-interactive execution") made both listings fail; the script's 2>/dev/null … || true read that as zero objects. No data was lost. Fix shipped (commit 07266be): verify fails closed — listing failure is exit 3 CHECK-ERROR (distinct from gcloud's "matched no objects" = legitimately empty), never a violation. The broken auth itself was the failing test (old: exit 2 wrong → new: exit 3). Monitor re-armed auth-aware.
Auth restored (evening 06-11) — first login refreshed the wrong account; the gitea config needs ben.stull@wiggleverse.org specifically; second login pinned to it. T-4 GREEN on the next check: over-age purged from the live set (demoted to a noncurrent version per versioning semantics), in-window object + prior noncurrent version intact (INV-5).
Ship — infra doc build-state bullet (SLICE-3) + spec changelog v0.2.2 (Version field also bumped from the stale v0.2.0); PR #54 → merged to main (a0c93c5d, remote branch deleted); issue #30 comment #1625; plan archived (plans/2026-06-10-gitea-backups-slice-3.md at 9c8926f); memory updated (next: SLICE-4).

Deferred decisions

T-4's over-age trigger is daysSinceCustomTime: 30, not prod's age: 30 — age cannot be back-dated; executing the literal prod rule means 30 days of wall clock. Same threshold, same lifecycle Delete engine; substitution recorded in the infra doc. Alternative: a scaled age: 1 scratch policy (slower, needs mid-wait uploads). Confidence high, but it is a fidelity call.
The 7-day noncurrent purge is config-verified, not execution-verified — executing it adds ≥ 7 days for the same Delete machinery already exercised. Versioning protection (prior versions survive) IS execution-verified.
Worktree left in place at finalize — branch merged + tree clean (teardown gate satisfied), but the worktree (.claude/worktrees/gitea-backups-slice-2) was operator-pre-created, not session-created, with sessions 0009/0017 still unfinalized — so it was flagged rather than removed.

Cut state / operator plate

Shipped & verified: SLICE-3 complete on main (PR #54); T-4 green 2026-06-11; prod untouched and drift-clean. Pipeline (§9) status: bootstrap infra, no UI/app deploy — the scratch bucket WAS the pre-prod gate per spec §7.3; nothing further to deploy.
Scratch bucket kept for SLICE-4's drill; t4 fixtures self-clean via the applied lifecycle (≤ 37 days).
Operator gotcha: gcloud reauth for ben.stull@wiggleverse.org (the gitea config's account) expires on an org policy cadence; long-running unattended gcloud work will hit it. CHECK-ERROR (exit 3) from t4-retention-check.sh means re-run gcloud auth login ben.stull@wiggleverse.org.
Sessions 0009 and 0017 remain --INPROGRESS (not this session's to adopt — they were live-listed at claim time).

Next-session prompt

/goal Build gitea-forge-backups SLICE-4 — restore runbook (RB-1/RB-2 → infra/backup-restore-gitea.md) + one proving drill onto a scratch Gitea, T-2 green, drill recorded, per specs/gitea-forge-backups.md §7.2 (engineering#30)
