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

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.
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.
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.
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.
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).
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.
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.)
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.
