## Launch prompt

```
Operator hit the sign-in resend-cooldown lockout: after sending a code to a mistyped email, the email-step Send button stayed disabled ("Resend in 31s") even after correcting the address, blocking them for the rest of the 60s window. Backend cooldown is correctly per-address (SD-0001 INV-3/PUC-2c); the lockout is a frontend state bug (SignIn.tsx cooldown not keyed to the address it was set for). Session goal: file Gitea issues (bug: frontend cooldown lockout; story: layered rate-limit hardening — per-address daily cap, per-IP limit), then fix the frontend bug in this session.

```

## Plan

> Anchor: #20 (wiggleverse/wiggleverse-ecomm, type/bug, P1 — sign-in resend cooldown
> locks out a corrected email address). ELIGIBLE per R2b (leaf bug).
> Sibling capture: #21 (type/story, P2 — OTP send rate-limit hardening; backlog only,
> not worked this session).

1. Capture: file bug #20 + story #21 on the ecomm tracker — **done** (#20 P1, #21 P2).
2. Fix #20 — **done**: new `frontend/src/cooldown.ts` (`cooldownAppliesTo`, normalization
   mirrors backend `normalize_email`/INV-2); `SignIn.tsx` tracks `cooldownFor` and gates
   the email-step button through it. Code-step resend unchanged.
3. Tests first — **done** (TDD, red→green): `frontend/src/cooldown.test.ts`, 5 cases incl.
   the lockout regression. (No RTL in repo — pure-logic module per repo convention.)
4. Verify — **done**: vitest 8/8, tsc clean, backend 68/68 untouched-green; live UI walk
   on the localhost stack (wrong address → "Wrong address?" → same address stays
   disabled w/ countdown; corrected address sends at once). PR #22 merged to main
   @ 6b405a0; issue #20 auto-closed. #21 remains open backlog.

## 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._

- **Priorities**: filed #20 as P1 (live UX lockout on the signup door) and #21 as P2
  (hardening, no active abuse). Operator may want to re-rank #21.
- **§9 pipeline**: localhost stage green (unit + typecheck + live-UI walk). **PPE deploy
  deferred** — PPE exists (PUC-11 rehearsal green 2026-06-11) but the deploy is a
  flotilla gesture with a version-pin bump and the E2E suite/pipeline automation is
  still being built (§10.6); no prod exists yet, so `ppe-before-prod` is not bypassed.
  The merged fix should ride the next PPE deploy.
- **E2E browser test**: not added as a Playwright artifact (suite not yet stood up,
  consistent with SLICE-3/4 deferral per §6.8); covered by a pure-logic vitest
  regression + a manual live-UI walk this session.
- **Scope**: left `.claude/launch.json` (preview launch config) untracked — local
  tooling, not repo surface.
