Session 0021.0 — Transcript

App: ecomm Start: 2026-06-10T08-20 (PST) Type: planning-and-executing Claude-Session: 7f254528-630c-4d45-a898-0382927ce8a4 End: 2026-06-10T08-53 (PST) Status: FINALIZED. Outcome: SLICE-1 (walking skeleton) of SD-0001 shipped — merged to main via PR #5 (merge commit 9373177); plan archived to wiggleverse-ecomm-content/plans/2026-06-10-slice-1-walking-skeleton.md.

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):

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.
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.
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)

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).
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).
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.
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.
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.
