## Launch prompt

`/goal Implement SLICE-2 (identity) of SD-0001 v0.3.0 — accounts domain (email +
one-time-code request-code/verify per INV-2/INV-3, signed-cookie sessions,
/api/auth/me + logout), platform/mailer port with LogMailer, Landing + Sign-in
screens, entry routing with storefront hard-wired null — per SD-0001 §7.2 (SLICE-2)`

## Plan

> Anchor: design `wiggleverse-ecomm-content/specs/SD-0001-mvp-sign-up-and-single-storefront.md`
> (v0.3.0, status `graduated` — R2a eligible; plan-eligibility gate passes).

**SLICE-2 — Identity** (SD-0001 §7.2). Built on the SLICE-1 walking skeleton
(merged to `origin/main` @ 9373177). Branch: `slice-2-identity` off `main`.

Shipped:
- `accounts` domain — request-code / verify / get_account (§6.4–6.5), enforcing
  INV-2 (email canonical key) and INV-3 (OTC handled like a secret: hashed,
  10-min expiry, single-use, ≤5 attempts, 60s resend cooldown).
- `platform/mailer` port (`send(to, subject, body)`) with `LogMailer` adapter.
- `platform/session` — signed HTTP-only cookie sessions (INV-8; no session table, §6.2).
- REST BFF auth endpoints in `main.py`: `request-code`, `verify`, `me`, `logout`.
- Frontend: Landing + Sign-in (two-step) screens, entry-routing rule with
  `storefront` hard-wired `null` (storefronts land in SLICE-3).

DoD met: BUC-1/BUC-2 acceptance end-to-end on localhost; scenario tests for
14.01.0001–0004, 0009–0011, PUC-2a/b/c, PUC-9; INV-2/INV-3 invariant tests;
no-enumeration uniform-204 asserted. `scripts/check.sh` green; merged via PR #6.

## Pre-state

- Worktree on the harness-provided branch `claude/agitated-heyrovsky-1a1f47`
  (the merged SLICE-1 branch); `origin/main` @ 9373177. Dev Postgres container up
  and healthy; `.venv` + `frontend/node_modules` present. Stray `.venv.bak` /
  `frontend/node_modules.bak` left over from SLICE-1's clean-checkout DoD sim
  (untracked; rm permission-denied in this session — harmless, never committed).
- SLICE-1's `migrations/0001_init.sql` already laid the full §6.3 schema
  (account / auth_code / storefront / storefront_membership), so SLICE-2 added
  **no migration** — only domain/service/BFF/frontend code over that schema.

## Session arc

1. **Gate + claim.** Classified the `/goal` as planning-and-executing; ran
   `wgl-planning-and-executing`. Peeked (dry-run) — no in-flight sessions — then
   claimed **0022** (atomic push, 30bb976). Verified baseline; started SLICE-2 on
   a fresh `slice-2-identity` branch off `origin/main`.
2. **Orient.** Read SD-0001 in full (§5 UX, §6.2–6.9 technical, §7.2 SLICE-2) and
   the entire SLICE-1 codebase (4-layer backend, migration runner, conftest
   fresh-DB fixture, Vite/React shell, check.sh/dev.sh) to match conventions.
3. **Plan.** Wrote `docs/superpowers/plans/2026-06-10-slice-2-identity.md` with
   `superpowers:writing-plans` — 8 TDD tasks, complete code in every step. Self-
   review fixed a weak HTTP test and two unused `response: Response` params.
   Design choices locked: HMAC-peppered code hash (no new dep), stdlib-HMAC signed
   cookies, `_storefront_for` null seam, Vitest for the §6.8 routing unit test,
   E2E deferred per §6.8.
4. **Execute (subagent-driven).** Dispatched implementer subagents (sonnet),
   reviewing each diff inline:
   - **Tasks 1–3** (config / mailer / session): clean, verbatim. 7+3+4 tests.
   - **Task 4** (accounts domain): the heart. Implementer flagged a sound TDD
     deviation — the plan's cooldown (`max(created_at)` over all codes) wrongly
     blocked re-login after a code is consumed; scoped it to `consumed_at IS NULL`.
     13 domain tests green.
   - **Tasks 5–6** (deps + BFF `/api/auth/*`): 43 backend tests green; lint kept.
   - **Task 7** (frontend): added Vitest + screens + routing. Implementer worked
     around the stray `node_modules.bak` with a committed `test.exclude`; I
     replaced it with the cleaner `vitest/config` + `test.include: ["src/**"]`
     (amended the commit) so no local-only workaround ships.
5. **Verify (Task 8).** Full `scripts/check.sh` green. The localhost end-to-end
   walk **caught a real gap**: uvicorn swallows the app's `ecomm.mailer` INFO log,
   so PUC-10's dev channel (the code in the backend log) was invisible — the unit
   tests read the in-memory outbox and missed it. Added an idempotent `ecomm`-
   logger handler in `create_app`; re-walked: request-code 204 → code-in-log →
   verify 200 + `created:true` + `storefront:null` + `HttpOnly; SameSite=lax`
   cookie → `/me` 200 → logout 204 → `/me` 401. README + version bumped (app
   `0.2`, frontend `0.2.0`).
6. **Final review.** A reviewer subagent over the whole diff (auth/security focus)
   returned **APPROVE_WITH_NITS** — no blockers; I-1/I-2 (mailer-failure ordering
   + missing 502) are SLICE-4 (SmtpMailer) concerns the spec already scopes there.
7. **Ship.** Pushed `slice-2-identity`; opened **PR #6** via the Gitea API; merged
   to `main` @ **1b40bde**. (No deploy — PPE/Prod is SLICE-4; merging to main is
   the integration point, as in SLICE-1.)
8. **Finalize.** Archived the plan to content `plans/` (2597adb); filed the
   SLICE-4 mailer-hardening findings as tracker **issue #7** (P2); updated memory
   + index; published this transcript.

## Cut state

- **Merged to `main` @ 1b40bde** (PR #6, 11 commits on `slice-2-identity`). Working
  tree clean except the untracked stray `.bak` dirs (never committed).
- `scripts/check.sh` green: import-linter `1 kept, 0 broken`; 43 backend pytest;
  frontend tsc+build; 3 Vitest routing tests.
- Plan archived: `wiggleverse-ecomm-content/plans/2026-06-10-slice-2-identity.md`
  (2597adb). Issue #7 filed for SLICE-4 mailer hardening.

## Deployment pipeline (§9) status

- **localhost:** green — unit + integration gate, plus a manual end-to-end HTTP walk.
- **E2E browser tests:** deferred this slice per spec §6.8 (no UI beyond forms yet);
  the §6.8-required entry-routing **unit** test is included. (Tension with §9's
  "E2E for any UI surface" logged in Deferred decisions.)
- **PPE / Prod:** not reachable yet — that infra is stood up in SLICE-4 (flotilla
  provisioning + Cloud SQL + SMTP). No deploy this slice; merge to `main` is the
  integration point.

## Deferred decisions

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

- **E2E browser tests deferred (spec §6.8 vs handbook §9).** SLICE-2 ships UI
  surfaces (Landing, Sign-in) but no Playwright E2E tests. The spec's testing
  strategy (§6.8) explicitly defers "component/E2E browser tests … until there is
  UI beyond forms"; the handbook §9 default is "E2E for any UI surface." Followed
  the reviewed spec (the more specific authority) and deferred E2E; the
  §6.8-required entry-routing **unit** test IS included. Revisit when SLICE-3 adds
  richer UI. (Low confidence on the §9 tension — flagging for operator.)
- **Cooldown semantics refined during TDD (sound).** The plan's resend-cooldown
  query counted all codes by `max(created_at)`, which wrongly blocked a legitimate
  re-login right after a code is consumed. Scoped it to **unconsumed** codes
  (`AND consumed_at IS NULL`) — anti-spam intent preserved (PUC-2c still blocks a
  rapid resend of a pending code), re-login unblocked. Test was ground truth.
- **Dev-log channel fix (verification-caught).** uvicorn configures only its own
  loggers, so the `LogMailer` INFO line — PUC-10's local dev channel (the one-time
  code in the backend log) — was swallowed. Added an idempotent dedicated handler
  for the `ecomm` logger in `create_app`. Unit tests read the in-memory outbox and
  hadn't caught it; the end-to-end walk did.
- **Mailer-failure hardening → SLICE-4 (final review, I-1/I-2; filed as issue #7).**
  `request_code` commits the code row *before* `mailer.send()`, and the BFF has no
  `502 delivery_failed` branch. Harmless this slice (`LogMailer` never fails) and
  the spec scopes `delivery_failed` to SLICE-4, but when `SmtpMailer` lands SLICE-4
  must: send-before-commit (or delete the row on send failure) so a delivery
  failure doesn't orphan a code and trip the cooldown (§6.9 "codes are
  re-requestable"), and add the `502 delivery_failed` handler (INV-9, §6.4).
- **Minor, MVP-accepted (final review).** request_code cooldown check isn't
  serialized (two concurrent requests for one email could both issue — low
  probability, not a security issue); 429 responses carry `retry_after_s` in the
  body (per §6.4) but no `Retry-After` HTTP header. Both fine for MVP.

## Next session

```
/goal Implement SLICE-3 (storefront) of SD-0001 v0.3.0 — storefronts domain (create_storefront + membership, INV-4 service-layer one-storefront guard over the many-capable schema, concurrent-create refusal) wired into the _storefront_for seam so verify/me return the real storefront; Create-storefront + Admin-shell screens (PUC-4/5/6/7/8); complete entry routing (create → admin); the whole-flow bootstrap test (INV-1, empty DB → sign-up → storefront → admin) — per wiggleverse-ecomm-content/specs/SD-0001-mvp-sign-up-and-single-storefront.md §7.2 (SLICE-3)
```

Read [[project_ecomm_clean]] for state + gotchas. SLICE-3 fills the
`_storefront_for` null seam in `main.py` and the routing rule's
`create-storefront`/`admin` branches. flotilla/GCP still waits for SLICE-4.
