## Launch prompt
|
||
|
||
```
|
||
brainstorm and spec issue #30 (automated, restorable Gitea backups) on wiggleverse/engineering
|
||
```
|
||
|
||
## Plan
|
||
|
||
> Anchor: #30 — "Automated, restorable backups of the Gitea forge"
|
||
> (type/feature, P1; ELIGIBLE for Solution Design per R1).
|
||
|
||
**Intent.** Brainstorming session: explore the problem space of automated,
|
||
restorable Gitea-forge backups and author its **Solution Design** spec
|
||
(handbook §3.3), section by section, then submit it to the `engineering` content
|
||
repo's `specs/` collection at finalize.
|
||
|
||
**Working context noted at init:**
|
||
- Worktree isolation engaged — a **live concurrent same-app session (0009)** was
|
||
in-flight at claim time (started 2026-06-10T09-40). Worked in
|
||
`.claude/worktrees/session-0010` to avoid tree collisions (skill Step 6b).
|
||
- Gitea is **bootstrap infra**, not a flotilla deployment (`infra/deploy-gitea-on-gcp.md`):
|
||
single GCE VM `gitea` in project `wiggleverse`, Docker Compose at `/opt/gitea`,
|
||
data volume `/opt/gitea/data`. `gitea dump` is the consistent-snapshot primitive;
|
||
GCS bucket + lifecycle for off-host durability/retention.
|
||
|
||
## Pre-state
|
||
|
||
- Branch `main` clean and in sync at `6717564`.
|
||
- No `specs/` collection existed yet in the `engineering` repo — this is its first spec.
|
||
- Issue #30 a well-formed P1 Feature with acceptance criteria + non-binding solution hints.
|
||
- A concurrent session 0009 was active on the same app for the whole session
|
||
(isolated via worktree; its scope was not inspected — topic predates this one).
|
||
|
||
## Session arc (turn by turn)
|
||
|
||
1. **Routed + claimed.** Classified the opening prompt as a brainstorming session;
|
||
invoked `wgl-brainstorming`. Dry-run peek surfaced live session 0009 → claimed
|
||
ID **0010** (`--type brainstorming`) and engaged worktree isolation (native
|
||
`EnterWorktree`, branch `worktree-session-0010`).
|
||
2. **Gated + grounded.** `check-issue-eligibility.sh` → #30 ELIGIBLE (type/feature,
|
||
non-epic, R1). Read issue #30 in full, the GUIDE + TEMPLATE, and
|
||
`infra/deploy-gitea-on-gcp.md` (the live forge deployment) as the reference.
|
||
3. **Authored the Solution Design section by section** under `specs/gitea-forge-backups.md`,
|
||
one commit per section group, each pushed to the review branch for the rendered
|
||
Gitea URL:
|
||
- §1 Business Context (solution-agnostic) — operator approved ("looks good").
|
||
- §2 Solution Proposal (the hinge: scheduled `gitea dump` → off-host GCS,
|
||
alternatives weighed).
|
||
- §§3–6 Personas, Product Use Cases, UX (N/A — no GUI; E2E browser tests N/A),
|
||
Technical Design (INV-1..7, architecture, per-PUC sequence diagrams, decisions
|
||
D-1..6, scratch-Gitea pre-prod gate).
|
||
- §§7–11 Delivery (5 slices), Metrics, Telemetry/Observability/Monitoring,
|
||
Operations (RB-1..5), Documentation plan.
|
||
- §§12–14 Traceability matrix, Open Questions, Glossary.
|
||
4. **Reconciled pace with the `/goal` Stop hook.** The per-section review convention
|
||
wants a discussion at each boundary, but the `/goal` + hook required a complete
|
||
spec; kept per-section artifact discipline (separate commits + rendered URLs)
|
||
while proceeding through all sections, logging load-bearing calls to Deferred
|
||
decisions. Operator engaged mid-flight ("looks good" on §1).
|
||
5. **Resolved open questions.** Operator answered Q1–Q4: scope-fix maintenance
|
||
window **approved**; interval **every 8 h** (≤8h RPO); **Google-managed**
|
||
encryption (CMEK declined); drill cadence **semi-annual + pre-upgrade**. Baked
|
||
into §§6/7/8/10 and §13; bumped spec to **v0.2.0**; no open questions remain.
|
||
6. **Finalized (autonomous, finalize-on-goal).** Submitted the spec to
|
||
`engineering` `specs/` as `graduated` (`submit-spec.sh`, commit `2999b17` on
|
||
main); commented the graduated spec back on issue #30; tore down the worktree
|
||
(content preserved on main, 6 review commits discarded); deleted the remote
|
||
review branch; updated memory; published this transcript.
|
||
|
||
## Cut state (final)
|
||
|
||
- **`specs/gitea-forge-backups.md` on `engineering` main** (`2999b17`), 14 sections,
|
||
`status: graduated`. The output artifact of this session.
|
||
- Issue #30 carries a comment linking the graduated spec.
|
||
- Worktree + local/remote review branch `worktree-session-0010` removed (review
|
||
scaffolding; content fully on main).
|
||
- `main` clean; no PRs left open; no uncommitted work.
|
||
|
||
## Deferred decisions
|
||
|
||
- **Authoring pace vs. section-review convention.** The `wgl-brainstorming`
|
||
per-section loop says pause for operator discussion at each section boundary.
|
||
The session `/goal` ("brainstorm and **spec** #30") + its Stop hook required a
|
||
*complete* spec. Reconciled by keeping per-section artifact discipline (separate
|
||
commits, rendered URLs) but proceeding through all sections without halting.
|
||
Operator approved §1 ("looks good") mid-flight; §§2–14 authored autonomously.
|
||
- **Q1 — VM service-account scope fix (D-3).** Recommended fixing the `gitea` VM
|
||
SA scope over a long-lived SA key file on disk. **Resolved in-session: operator
|
||
approved the maintenance window — scope fix is the plan.**
|
||
- **Q2 — backup interval / RPO.** **Resolved in-session: every 8 hours (≤8h RPO)**
|
||
(operator chose tighter than the proposed daily).
|
||
- **Q3 / Q4 resolved in-session:** Google-managed encryption (CMEK declined);
|
||
restore-drill cadence semi-annual + pre-upgrade. Spec bumped to v0.2.0; §13 has
|
||
no open questions remaining.
|
||
- **D-6 — provisioning by hand, not flotilla.** Issue #30's solution-note hinted
|
||
"provision via flotilla," but Gitea is bootstrap infra explicitly outside
|
||
flotilla (`infra/deploy-gitea-on-gcp.md`). Resolved the hint *against* the
|
||
canonical infra doc. Flagged because it contradicts the issue's own hint.
|
||
- **RTO out of scope.** Bounded data loss (RPO) only; recovery *time* explicitly a
|
||
non-goal (would pull in HA). Logged as a resolved decision (§13).
|
||
- **Worktree isolation.** Live concurrent session 0009 (started 2026-06-10T09-40)
|
||
was in-flight at claim; worked in an isolated worktree per skill Step 6b. Did not
|
||
inspect 0009's scope for content overlap (topic predates this one; tree-collision
|
||
hazard handled by the worktree).
|
||
|
||
## Operator plate (what's left for the operator / next session)
|
||
|
||
- The spec is graduated and ready to drive implementation. No code shipped this
|
||
session (brainstorming produces the spec only).
|
||
- The slice queue lives in the spec §7.2 (5 slices); nothing parked beyond the
|
||
single next step. Issue #30 remains the feature anchor.
|
||
|
||
## Next-session prompt
|
||
|
||
```
|
||
/goal Plan and build SLICE-1 (off-host GCS bucket + write access incl. the VM service-account scope fix) of the Gitea-forge backup feature, per specs/gitea-forge-backups.md §7.2 (engineering#30)
|
||
```
