## Launch prompt

```
/goal Implement SLICE-3 (storefront) of SD-0001 v0.3.0 — storefronts domain (create_storefront + membership, INV-4 guard, concurrent-create refusal) wired into the _storefront_for seam; Create-storefront + Admin-shell screens (PUC-4/5/6/7/8) following the Claude Design export at wiggleverse-ecomm-content/ui/designs/ecomm-login-and-create-storefront-designs/; complete entry routing; whole-flow INV-1 bootstrap test — per SD-0001 §7.2 (SLICE-3). Update any UI in slices 1 and 2 based on the designs

```

## Plan

> Anchor: design /Users/benstull/git/wiggleverse.org/wiggleverse/wiggleverse-ecomm-content/specs/SD-0001-mvp-sign-up-and-single-storefront.md (R2a — ELIGIBLE)

Implement SLICE-3 (storefront) per SD-0001 v0.3.0 §7.2:

1. `storefronts` domain — `create_storefront` + membership, INV-4 guard,
   concurrent-create refusal.
2. Wire into the BFF `_storefront_for` seam (replace the `null` stub).
3. Create-storefront + Admin-shell screens (PUC-4/5/6/7/8) per the Claude
   Design export at `wiggleverse-ecomm-content/ui/designs/ecomm-login-and-create-storefront-designs/`.
4. Complete entry routing (signed-in users route by storefront presence).
5. Whole-flow INV-1 bootstrap test.
6. Update SLICE-1/2 UI (Landing, Sign-in) to match the design export.

## Execution record

- All 10 plan tasks executed TDD, commits ba8b493…877be24.
- **SHIPPED:** PR #9 merged to `main` at `0747181`
  (https://git.wiggleverse.org/wiggleverse/wiggleverse-ecomm/pulls/9).
- Gate green twice (pre- and post-walkthrough): import contract kept, **62 backend
  tests** passed (was 46), frontend typecheck + build + 3 vitest.
- PUC-10 walked end to end on localhost **through the real UI** (Playwright,
  throwaway sandbox): landing → sign-up → code from the dev log → create
  storefront ("Ben's Bets") → honestly-empty admin → sign-out. Screenshots
  verified against the design export (landing / code-entry / create / admin).
- Two execution-time fixes beyond the plan text:
  1. `_signed_in_client` test helper rewritten as a `@contextmanager` (manually
     calling `__enter__` then re-entering via `with` closed the lifespan pool —
     `PoolClosed`). Plan file updated to the executed form.
  2. The walkthrough caught a real a11y bug: `Field`'s label wasn't associated
     with its input (§6.6 demands labelled fields) — fixed with `useId`/`htmlFor`.
- Backend FastAPI version → 0.3, frontend → 0.3.0; README status → SLICE-3 in
  place, SLICE-4 (deployed environments) next.
- Canonical checkout had no venv (prior session worked in a worktree) — created
  `.venv` + installed backend deps; frontend `node_modules` installed likewise.

## Deferred decisions

_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._

- **E2E browser tests deferred** per SD-0001 §6.8 ("component/E2E browser tests
  deferred until there is UI beyond forms") — SLICE-3's UI is still forms + text;
  same stance as SLICE-1/2. The §9 pipeline policy is noted, not yet automated.
- **Design-fidelity divergence (honest-UI):** the design export's dead `#` links
  ("How it works", "Open Core", footer Privacy/Terms) are not shipped — INV-9's
  spirit (nothing links nowhere). Footer keeps the identity line only.
- **Welcome-banner placement:** the hf-signin design shows the PUC-3 honest-copy
  banner on the code step; the SPA routes immediately after verify, so the banner
  renders on the destination screen (create-storefront/admin) instead.
- **INV-4 concurrency mechanism:** per-account `pg_advisory_xact_lock(account_id)`
  serializes guard+insert (spec asks only that "two concurrent creates cannot both
  pass the guard"; the advisory lock is the lightest way without a schema UNIQUE,
  which INV-4 forbids).
