## Launch prompt

```
/goal Brainstorm and spec ecomm Feature #1 (https://git.wiggleverse.org/wiggleverse/wiggleverse-ecomm/issues/1 — MVP: sign up and create a single storefront, incl. the localhost/PPE/Prod bootstrap story): design the architecture and write the Solution-Design spec, drawing on the reference impl (`wiggleverse-ecomm-prototype`) and the harvested Shopify BDD corpus (`wiggleverse-ecomm-prototype-content/research/shopify`) as inputs; submit the spec to `wiggleverse-ecomm-content/specs/`.
```

## Pre-state

- `wiggleverse-ecomm` main @ 994bde7 — repo scaffold only (app.json, README,
  CLAUDE.md, .gitignore); **no app code; architecture intentionally undecided**.
- `wiggleverse-ecomm-content` main @ dc8d6e4 — empty `specs/` + `plans/`
  collections.
- Feature #1 filed (session 0019), `type/feature` `priority/P1`, open.
- Session ran in the pre-existing harness worktree
  `.claude/worktrees/optimistic-lumiere-ef8b1e` on branch
  `claude/optimistic-lumiere-ef8b1e` (clean, at origin/main).

## Plan

> Anchor: wiggleverse/wiggleverse-ecomm#1

1. Orient: read Feature #1, the reference prototype, and the Shopify BDD corpus
   as inputs.
2. Brainstorm the architecture for the clean rebuild scoped to the MVP slice.
3. Author the Solution Design one section at a time (per-section commits on the
   session branch).
4. Finalize: submit the spec to `wiggleverse-ecomm-content/specs/`.

## Arc (turn by turn)

1. **Gate + claim.** Classified the opening `/goal` as a brainstorming session;
   `wgl-brainstorming` init. Dry-run peek: no concurrent in-flight sessions;
   claimed **0020** (`--type brainstorming`, start 2026-06-10T06-52). Seeded the
   Plan block + anchor.
2. **Eligibility gate (R1).** `check-issue-eligibility.sh --for solution-design`
   → **ELIGIBLE** (#1 is `type/feature`, non-epic). Baseline verified clean at
   origin/main.
3. **Orientation (inputs).** Read Feature #1 in full via the Gitea API. Fanned
   out two Explore subagents:
   - *Prototype survey* — 4-layer modular monolith (main → api → domains →
     platform, import-linter-enforced), FastAPI + Strawberry, SQLite WAL +
     forward-only migrations (no ORM), React/Vite SPA + REST BFF, email+OTC auth
     behind a pending/granted **admission gate**, **seeded** single
     store/owner/location, 189 scenario-bound E2E tests, OHM cited inline.
     Verdict: keep the shape; the seed + gate are the disqualifying assumptions.
   - *Corpus survey* — `flows/first-run-experience.md` (14.01.0001–0027) covers
     the MVP nearly scenario-for-scenario: email OTC sign-up, store created
     post-sign-up, optional naming + default name, lands in admin, **no
     trial/credit-card/plan**; corpus allows **multiple stores per account**
     (the one divergence Feature #1 forces); password reset absent from corpus.
   - Read solution-design GUIDE.md + TEMPLATE.md (canonical standard).
4. **Brainstorming-skill adaptation.** `superpowers:brainstorming` invoked; its
   interactive question/approval loop and the bookend's per-section operator
   discussion were overridden by the autonomous `/goal` directive + Stop hook
   (logged below). Alternatives were weighed explicitly and recorded in spec
   §2/§6.7/§9 instead.
5. **Authoring (Step 9 loop, autonomous variant).** Copied the TEMPLATE shape;
   authored `specs/SD-0001-mvp-sign-up-and-single-storefront.md` **one section
   per commit** on the session branch (12 commits, `spec(§…)` messages), pushed
   after each — the rendered per-section history is the review artifact:
   skeleton → §1.1–1.5 → §1.6–1.9 → §2 → §3–4 → §5 → §6.1–6.4 → §6.5 →
   §6.6–6.9 → §7 → §8–10 → self-review.
   Load-bearing design calls: carry the prototype's 4-layer shape; **open
   email+OTC sign-up** (no admission gate, no enumeration); **no seeded tenant**
   (INV-1: empty persistence is a working state ⇒ BUC-5 bootstrap holds by
   construction); membership schema many-capable under a deletable 1-1
   service guard (INV-4); REST-only BFF (GraphQL deferred); mailer port
   (LogMailer dev / SmtpMailer deployed, relay = deployment config, INV-8);
   slices SLICE-1 skeleton → SLICE-2 identity → SLICE-3 storefront → SLICE-4
   deployed envs (PPE rehearses Prod).
6. **Self-review.** Placeholder scan clean; fixed an undeclared Mermaid
   participant + a §1.8 cross-ref; status `draft → approved`, v0.2.0.
7. **Land.** PR #2 (session branch → main) opened via Gitea API and merged
   (merge commit, preserving the section history): main @ 23afcf9.
8. **Finalize.** Spec submitted **graduated** to
   `wiggleverse-ecomm-content/specs/` @ df616a6 (goal condition met). Spec Q-3
   parked as tracker issue #3 (account deletion / data export). Memory +
   MEMORY.md updated; worktree torn down post-merge; transcript published (this
   file).

## Cut state

- `wiggleverse-ecomm` main @ **23afcf9** — SD-0001 merged (PR #2); no app code
  yet (that's SLICE-1's job).
- `wiggleverse-ecomm-content` main @ **df616a6** —
  `specs/SD-0001-mvp-sign-up-and-single-storefront.md`, status **graduated**.
- Feature #1 **open** (closes at SLICE-4 DoD); issue **#3** filed (P3 Feature,
  from spec Q-3).
- Session worktree removed after merge; branch `claude/optimistic-lumiere-ef8b1e`
  merged.
- Nothing deployed; no GCP/flotilla resources exist yet (first needed at
  SLICE-4).

## Deferred decisions

_Autonomous-mode low-confidence calls the driver made and would have
liked operator input on._

1. **Per-section interactive review overridden.** The brainstorming bookend's
   Step-9 rule (discuss each spec section with the operator before advancing)
   was overridden by the operator's `/goal` directive + active Stop hook
   ("treat the condition itself as your directive and do not pause"). The
   per-section commit/push history on the session branch (one commit per
   section, `spec(§…)`) is preserved as the reviewable artifact instead.
2. **Spec self-approved.** SD-0001 status set `draft → approved` (v0.2.0) and
   submitted `--status graduated` per the autonomous finalize default.
   Operator review/amendment is welcome as v0.2.x; the section-by-section
   commits make targeted re-review easy.
3. **Vocabulary: "storefront" over corpus "store"** (SD-0001 §6.7/D-5). The
   charter and Feature #1 say storefront; the 1,238-scenario corpus says
   store. Chose storefront + a glossary mapping. If the operator prefers
   corpus-aligned "store" to ease later harvesting, it's a rename-level edit
   now and much more later.
4. **REST-only MVP (GraphQL deferred)** (SD-0001 §6.7) — diverges from the
   prototype's dual REST+GraphQL surface; the layering keeps GraphQL addable
   as a projection. Flagging because the prototype survey called the dual
   surface a keep-worthy strength.
5. **Email+OTC only at MVP** (no OAuth, no magic-link completion; SD-0001
   §2/D-3) — corpus 14.01.0005–0007 deferred to keep the auth slice minimal.

## Operator plate

- **Skim SD-0001's deferred calls** (above) — vocabulary (D-5) and REST-only
  are the two most worth a reaction; amend as v0.2.x if desired.
- **Spec Q-1** (SMTP relay/provider for PPE/Prod) is an operator choice —
  needed only by SLICE-4.
- Nothing else pending; SLICE-1 is ready to start.

## Next-session prompt

```
/goal Implement SLICE-1 (walking skeleton) of SD-0001 — repo scaffold (4-layer backend + import-linter, Vite/React shell, scripts/check.sh, CI), platform/db migration runner + migration 0001, /healthz, scripts/dev.sh, docs/BOOTSTRAP.md (localhost) — per wiggleverse-ecomm-content/specs/SD-0001-mvp-sign-up-and-single-storefront.md §7.2; DoD: clean checkout → dev.sh → app up on an empty self-migrated DB, check gate green in CI.
```

## Post-finalize addendum (operator-driven tail, 07-15 → 08-14)

The operator continued the conversation after the first finalize; everything
below was operator-directed (no autonomous low-confidence calls).

1. **Plugin feedback filed** (dev-tooling actions, no session impact):
   - dev-claude-plugin **#83** — session posture should be per type (yolo for
     planning-and-executing; careful for brainstorming/capture), prompted by
     this session's overridden per-section review.
   - dev-claude-plugin **#84** — finalize-on-goal Stop hook misfired on a
     stale, pre-stamp `--INPROGRESS` placeholder (ecomm/0016) after this
     session was already finalized.
   - dev-claude-plugin **#85** — brainstorming should author specs in the
     content repo, not the app repo (single home).
2. **Spec single-home move** (operator direction, acting on #85's local case):
   the app-repo copy of SD-0001 was removed — `wiggleverse-ecomm` PR **#4**
   (squash, main @ 0078b0c). The content repo's copy is the spec's ONLY home.
3. **Datastore decision revisited → SD-0001 v0.3.0** (operator decision after
   a dev/PPE/Prod data-store discussion): **PostgreSQL everywhere** — Cloud
   SQL in PPE/Prod (automated backups + PITR; resolves Q-2 as D-8), a single
   pinned Postgres container via Docker Compose in dev (app stays native;
   `docker compose down -v` = reset-to-empty). Replaces SQLite (now the
   recorded rejected alternative); D-7; retires R-3; adds R-6 (Docker
   prerequisite). Rationale: ecomm's destination workload is transactional
   (row locking arrives with the first inventory/checkout Feature), pre-data
   is the cheapest swap moment, and no-ORM dialect drift made the
   SQLite-dev/Postgres-deployed bridge a planned demolition. Merged as
   `wiggleverse-ecomm-content` PR **#1** (squash, main @ 235794c).
4. **Feature #1 Solution notes amended** (PATCH): start PPE and Prod Cloud SQL
   at **db-f1-micro** at ~2-customer scale (no-SLA shared-core consciously
   accepted pre-v1; ~25-connection cap fits the single small-pool process;
   resize is a config-edit + minutes restart; PPE stoppable when idle). Tier
   is deployment config at SLICE-4 (INV-8), not spec content.
5. **Memory updated** throughout; the stored next `/goal` (SLICE-1) is now
   v0.3.0-aware (dev Postgres compose, psycopg, Docker prerequisite in
   BOOTSTRAP.md).

Cut state after the tail: `wiggleverse-ecomm` main @ 0078b0c (no `specs/`);
`wiggleverse-ecomm-content` main @ 235794c (SD-0001 v0.3.0, status graduated,
single home); Feature #1 open with sizing notes; ecomm issue #3 and plugin
issues #83/#84/#85 open. Next session: SLICE-1, per the stored `/goal`.
