## Launch prompt

```
Implement SLICE-1 (walking skeleton) of SD-0001 v0.3.0 — repo scaffold (4-layer
backend + import-linter, Vite/React shell, scripts/check.sh, CI), dev Postgres
compose (single pinned service), platform/db (psycopg) migration runner +
migration 0001, /healthz, scripts/dev.sh (owns container lifecycle),
docs/BOOTSTRAP.md (localhost, Docker prereq) — per
wiggleverse-ecomm-content/specs/SD-0001-mvp-sign-up-and-single-storefront.md §7.2.
DoD: clean checkout → dev.sh → app up on an empty self-migrated Postgres, check
gate green in CI.

```

## Plan

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

**Goal:** Implement SLICE-1 (walking skeleton) of SD-0001 §7.2 — the localhost
half of BUC-5 (PUC-10).

**Ships:** repo scaffold (4-layer Python backend `main > domains > platform` +
import-linter contract; Vite/React shell; `scripts/check.sh`; Gitea CI); dev
Postgres compose (single pinned service, named volume, healthcheck); `platform/db`
(psycopg + small pool) with the forward-only migration runner (INV-7, advisory-lock
+ fail-stop) and migration `0001` (the §6.3 schema: account, auth_code, storefront,
storefront_membership); `/healthz` (process up + DB reachable + migrations current);
`scripts/dev.sh` (owns the container lifecycle); `docs/BOOTSTRAP.md` (localhost
section, Docker prerequisite).

**DoD:** clean checkout → `scripts/dev.sh` → app up on an empty, self-migrated
Postgres; `/healthz` green; `scripts/check.sh` gate green in CI; bootstrap test
skeleton runs migrate-from-empty + idempotent re-migrate (INV-1 partial).

Work on branch `claude/agitated-heyrovsky-1a1f47` (this worktree) → PR → merge to
`main`. Plan archived to the content repo `plans/` at finalize.

**Status: COMPLETE.** All 11 plan tasks done; 13 commits on the branch. DoD verified:
clean-checkout simulation (`.venv` + `node_modules` moved aside, `compose down -v`) →
`scripts/dev.sh` → `/healthz` 200 `{"status":"ok"}` on an empty self-migrated Postgres
(0 accounts, migration 0001 applied); `scripts/check.sh` green (lint-imports kept, 7
pytest passed, frontend tsc+build); CI workflow written (inert until a Gitea runner).

**Plan deviations (all green, recorded for the archived plan):**
1. **`app/main.py` stub added in Task 1** (not Task 5): import-linter's `layers`
   contract requires every named layer module to exist, so the top layer needed a stub
   from the start; Task 5 fleshed it into the real factory.
2. **Frontend tsconfig simplified**: the planned `tsconfig.node.json` project-reference
   tripped `tsc` error TS6310 (composite project may not disable emit). Dropped the
   split for a single `tsconfig.json` that typechecks `src`; Vite loads its own config
   via esbuild (no tsc needed). One file, same gate.
3. **`scripts/dev.sh` portability fixes** (post-first-run): macOS ships bash 3.2 which
   lacks `wait -n` → replaced with a `kill -0` poll loop; and `npm` spawns `vite` as a
   grandchild, so cleanup now recurses `pgrep -P` to reap the whole subtree (Ctrl-C now
   frees both :8000 and :5173). Both verified.

## Session arc (turn-by-turn)

1. **Route + claim.** Opened via `/goal` (SLICE-1). Classified as
   planning-and-executing; ran `wgl-planning-and-executing`. Peeked (no concurrent
   sessions) and claimed ID **0021**. Verified clean `origin/main` baseline (repo was
   the bare greenfield scaffold). Plan-eligibility gate: ELIGIBLE (R2a — anchored on
   the graduated SD-0001 design).
2. **Study prior art.** Dispatched an Explore agent over the read-only
   `wiggleverse-ecomm-prototype` to harvest its proven shape: 4-layer package, the
   `.importlinter` contract, the SQLite migration-runner *pattern* (to port to
   psycopg), `check.sh`/CI, Vite proxy. Confirmed toolchain (Python 3.13.2, Node 24,
   Docker running, compose v2.33).
3. **Plan.** Wrote the JIT plan (`superpowers:writing-plans`) →
   `docs/superpowers/plans/2026-06-10-slice-1-walking-skeleton.md` (11 tasks, TDD,
   bite-sized). Self-review caught and fixed three issues pre-execution: pytest
   `pythonpath`, a stale note, and split imports in `main.py`.
4. **Execute (`superpowers:executing-plans`, inline — sequential + env-dependent).**
   Tasks 1→11, each committed:
   - T1 skeleton + deps + contract — hit "missing layer `app.main`": import-linter
     `layers` needs every named module to exist → added a `main.py` stub.
   - T2 config (TDD). T3 compose (postgres:16, healthy, psycopg connects).
   - T4 migration runner + migration 0001 (TDD; 3 tests; confirmed psycopg3
     multi-statement `execute` works for the whole `.sql` file).
   - T5 factory + `/healthz` (TDD; 7 tests green; manual `curl` 200 after clearing a
     stray :8000). T6 `check.sh`. T7 `dev.sh`. T8 frontend — hit TS6310 (composite
     project may not disable emit) → collapsed to a single `tsconfig.json`; whole
     gate green. T9 CI. T10 `docs/BOOTSTRAP.md`.
   - T11 DoD: clean-checkout sim (moved `.venv` + `node_modules` aside,
     `compose down -v`) → `dev.sh` → `/healthz` 200 on empty self-migrated DB (0
     accounts, migration 0001 applied). Found + fixed two `dev.sh` portability bugs
     (bash-3.2 `wait -n`; npm→vite grandchild orphan) and re-verified clean run +
     trap teardown. README status updated.
5. **Ship + finalize.** Checkpointed the transcript; pushed; created
   **PR #5** via the Gitea API (`gitea-api.sh`); merged to `main`; archived the plan
   to the content repo; updated memory; published this transcript.

## Cut state (where it ends)

- `main` @ 9373177 carries all of SLICE-1; tracked tree clean. Branch
  `claude/agitated-heyrovsky-1a1f47` merged (worktree is harness-owned under
  `.claude/worktrees/`, left for the harness to reclaim; an untracked
  `frontend/node_modules.bak/` from the clean-checkout sim is gitignore-irrelevant —
  never added — and goes with the worktree).
- Gate green locally; **CI is inert until a Gitea Actions runner is registered**
  (carried over from the prototype's standing state).
- **Deployment pipeline (§9):** SLICE-1 is infrastructure with no deployable UI and
  no E2E browser harness yet (browser E2E deferred per §6.8 until there's UI beyond
  forms). Localhost gate is the only stage that exists; PPE/Prod deploy is SLICE-4.
  Nothing to ship beyond the merge.

## Operator plate (what to skim)

- **One deferred-decision call:** Postgres pinned to **16** (D-7 says "Cloud SQL
  major version" but that major isn't fixed until SLICE-4 provisioning). One-line
  change in `compose.yaml` + `.gitea/workflows/ci.yml` if you'd prefer 17/other.
- Nothing parked beyond the single next `/goal` (SLICE-2) — the remaining slices
  live in the spec's §7.2 delivery plan + Feature #1.

## Next session

```
/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 wiggleverse-ecomm-content/specs/SD-0001-mvp-sign-up-and-single-storefront.md §7.2 (SLICE-2); DoD: BUC-1/BUC-2 acceptance met end-to-end on localhost; scenario tests 14.01.0001–0004/0009–0011 + PUC-2a/b/c + INV-2/INV-3 green; uniform-204 no-enumeration asserted.
```

## 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._

- **Postgres major version pin = 16.** Spec §6.7/D-7 says the dev container is
  "pinned to the Cloud SQL major version" but the eventual Cloud SQL instance major
  isn't fixed yet (SLICE-4 provisioning, Q-1-adjacent). Chose `postgres:16` —
  mature, widely available, a safe Cloud SQL default. If the operator wants 17 (or to
  match a specific Cloud SQL choice) it's a one-line change in `compose.yaml` +
  `.gitea/workflows/ci.yml`. Low blast radius pre-data.
