## 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.

## 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).
