Session 0020.0 — Transcript

App: ecomm Start: 2026-06-10T06-52 (PST) · End: 2026-06-10T07-15 (PST) Type: brainstorming Claude-Session: 70151e40-bc9e-4ddb-b5ab-20996158978f Anchor: wiggleverse/wiggleverse-ecomm#1 (Feature — MVP: sign up + create a single storefront) Mode: autonomous (yolo default) throughout

Launch prompt

/goal Brainstorm and spec ecomm Feature #1 (https://git.wiggleverse.org/wiggleverse/wiggleverse-ecomm/issues/1 — MVP: sign up and create a single storefront, incl. the localhost/PPE/Prod bootstrap story): design the architecture and write the Solution-Design spec, drawing on the reference impl (`wiggleverse-ecomm-prototype`) and the harvested Shopify BDD corpus (`wiggleverse-ecomm-prototype-content/research/shopify`) as inputs; submit the spec to `wiggleverse-ecomm-content/specs/`.

Pre-state

  • wiggleverse-ecomm main @ 994bde7 — repo scaffold only (app.json, README, CLAUDE.md, .gitignore); no app code; architecture intentionally undecided.
  • wiggleverse-ecomm-content main @ dc8d6e4 — empty specs/ + plans/ collections.
  • Feature #1 filed (session 0019), type/feature priority/P1, open.
  • Session ran in the pre-existing harness worktree .claude/worktrees/optimistic-lumiere-ef8b1e on branch claude/optimistic-lumiere-ef8b1e (clean, at origin/main).

Plan

Anchor: wiggleverse/wiggleverse-ecomm#1

  1. Orient: read Feature #1, the reference prototype, and the Shopify BDD corpus as inputs.
  2. Brainstorm the architecture for the clean rebuild scoped to the MVP slice.
  3. Author the Solution Design one section at a time (per-section commits on the session branch).
  4. Finalize: submit the spec to wiggleverse-ecomm-content/specs/.

Arc (turn by turn)

  1. Gate + claim. Classified the opening /goal as a brainstorming session; wgl-brainstorming init. Dry-run peek: no concurrent in-flight sessions; claimed 0020 (--type brainstorming, start 2026-06-10T06-52). Seeded the Plan block + anchor.
  2. Eligibility gate (R1). check-issue-eligibility.sh --for solution-designELIGIBLE (#1 is type/feature, non-epic). Baseline verified clean at origin/main.
  3. Orientation (inputs). Read Feature #1 in full via the Gitea API. Fanned out two Explore subagents:
    • Prototype survey — 4-layer modular monolith (main → api → domains → platform, import-linter-enforced), FastAPI + Strawberry, SQLite WAL + forward-only migrations (no ORM), React/Vite SPA + REST BFF, email+OTC auth behind a pending/granted admission gate, seeded single store/owner/location, 189 scenario-bound E2E tests, OHM cited inline. Verdict: keep the shape; the seed + gate are the disqualifying assumptions.
    • Corpus surveyflows/first-run-experience.md (14.01.00010027) covers the MVP nearly scenario-for-scenario: email OTC sign-up, store created post-sign-up, optional naming + default name, lands in admin, no trial/credit-card/plan; corpus allows multiple stores per account (the one divergence Feature #1 forces); password reset absent from corpus.
    • Read solution-design GUIDE.md + TEMPLATE.md (canonical standard).
  4. Brainstorming-skill adaptation. superpowers:brainstorming invoked; its interactive question/approval loop and the bookend's per-section operator discussion were overridden by the autonomous /goal directive + Stop hook (logged below). Alternatives were weighed explicitly and recorded in spec §2/§6.7/§9 instead.
  5. Authoring (Step 9 loop, autonomous variant). Copied the TEMPLATE shape; authored specs/SD-0001-mvp-sign-up-and-single-storefront.md one section per commit on the session branch (12 commits, spec(§…) messages), pushed after each — the rendered per-section history is the review artifact: skeleton → §1.11.5 → §1.61.9 → §2 → §34 → §5 → §6.16.4 → §6.5 → §6.66.9 → §7 → §810 → self-review. Load-bearing design calls: carry the prototype's 4-layer shape; open email+OTC sign-up (no admission gate, no enumeration); no seeded tenant (INV-1: empty persistence is a working state ⇒ BUC-5 bootstrap holds by construction); membership schema many-capable under a deletable 1-1 service guard (INV-4); REST-only BFF (GraphQL deferred); mailer port (LogMailer dev / SmtpMailer deployed, relay = deployment config, INV-8); slices SLICE-1 skeleton → SLICE-2 identity → SLICE-3 storefront → SLICE-4 deployed envs (PPE rehearses Prod).
  6. Self-review. Placeholder scan clean; fixed an undeclared Mermaid participant + a §1.8 cross-ref; status draft → approved, v0.2.0.
  7. Land. PR #2 (session branch → main) opened via Gitea API and merged (merge commit, preserving the section history): main @ 23afcf9.
  8. Finalize. Spec submitted graduated to wiggleverse-ecomm-content/specs/ @ df616a6 (goal condition met). Spec Q-3 parked as tracker issue #3 (account deletion / data export). Memory + MEMORY.md updated; worktree torn down post-merge; transcript published (this file).

Cut state

  • wiggleverse-ecomm main @ 23afcf9 — SD-0001 merged (PR #2); no app code yet (that's SLICE-1's job).
  • wiggleverse-ecomm-content main @ df616a6specs/SD-0001-mvp-sign-up-and-single-storefront.md, status graduated.
  • Feature #1 open (closes at SLICE-4 DoD); issue #3 filed (P3 Feature, from spec Q-3).
  • Session worktree removed after merge; branch claude/optimistic-lumiere-ef8b1e merged.
  • Nothing deployed; no GCP/flotilla resources exist yet (first needed at SLICE-4).

Deferred decisions

Autonomous-mode low-confidence calls the driver made and would have liked operator input on.

  1. Per-section interactive review overridden. The brainstorming bookend's Step-9 rule (discuss each spec section with the operator before advancing) was overridden by the operator's /goal directive + active Stop hook ("treat the condition itself as your directive and do not pause"). The per-section commit/push history on the session branch (one commit per section, spec(§…)) is preserved as the reviewable artifact instead.
  2. Spec self-approved. SD-0001 status set draft → approved (v0.2.0) and submitted --status graduated per the autonomous finalize default. Operator review/amendment is welcome as v0.2.x; the section-by-section commits make targeted re-review easy.
  3. Vocabulary: "storefront" over corpus "store" (SD-0001 §6.7/D-5). The charter and Feature #1 say storefront; the 1,238-scenario corpus says store. Chose storefront + a glossary mapping. If the operator prefers corpus-aligned "store" to ease later harvesting, it's a rename-level edit now and much more later.
  4. REST-only MVP (GraphQL deferred) (SD-0001 §6.7) — diverges from the prototype's dual REST+GraphQL surface; the layering keeps GraphQL addable as a projection. Flagging because the prototype survey called the dual surface a keep-worthy strength.
  5. Email+OTC only at MVP (no OAuth, no magic-link completion; SD-0001 §2/D-3) — corpus 14.01.00050007 deferred to keep the auth slice minimal.

Operator plate

  • Skim SD-0001's deferred calls (above) — vocabulary (D-5) and REST-only are the two most worth a reaction; amend as v0.2.x if desired.
  • Spec Q-1 (SMTP relay/provider for PPE/Prod) is an operator choice — needed only by SLICE-4.
  • Nothing else pending; SLICE-1 is ready to start.

Next-session prompt

/goal Implement SLICE-1 (walking skeleton) of SD-0001 — repo scaffold (4-layer backend + import-linter, Vite/React shell, scripts/check.sh, CI), platform/db migration runner + migration 0001, /healthz, scripts/dev.sh, docs/BOOTSTRAP.md (localhost) — 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 DB, check gate green in CI.

Post-finalize addendum (operator-driven tail, 07-15 → 08-14)

The operator continued the conversation after the first finalize; everything below was operator-directed (no autonomous low-confidence calls).

  1. Plugin feedback filed (dev-tooling actions, no session impact):
    • dev-claude-plugin #83 — session posture should be per type (yolo for planning-and-executing; careful for brainstorming/capture), prompted by this session's overridden per-section review.
    • dev-claude-plugin #84 — finalize-on-goal Stop hook misfired on a stale, pre-stamp --INPROGRESS placeholder (ecomm/0016) after this session was already finalized.
    • dev-claude-plugin #85 — brainstorming should author specs in the content repo, not the app repo (single home).
  2. Spec single-home move (operator direction, acting on #85's local case): the app-repo copy of SD-0001 was removed — wiggleverse-ecomm PR #4 (squash, main @ 0078b0c). The content repo's copy is the spec's ONLY home.
  3. Datastore decision revisited → SD-0001 v0.3.0 (operator decision after a dev/PPE/Prod data-store discussion): PostgreSQL everywhere — Cloud SQL in PPE/Prod (automated backups + PITR; resolves Q-2 as D-8), a single pinned Postgres container via Docker Compose in dev (app stays native; docker compose down -v = reset-to-empty). Replaces SQLite (now the recorded rejected alternative); D-7; retires R-3; adds R-6 (Docker prerequisite). Rationale: ecomm's destination workload is transactional (row locking arrives with the first inventory/checkout Feature), pre-data is the cheapest swap moment, and no-ORM dialect drift made the SQLite-dev/Postgres-deployed bridge a planned demolition. Merged as wiggleverse-ecomm-content PR #1 (squash, main @ 235794c).
  4. Feature #1 Solution notes amended (PATCH): start PPE and Prod Cloud SQL at db-f1-micro at ~2-customer scale (no-SLA shared-core consciously accepted pre-v1; ~25-connection cap fits the single small-pool process; resize is a config-edit + minutes restart; PPE stoppable when idle). Tier is deployment config at SLICE-4 (INV-8), not spec content.
  5. Memory updated throughout; the stored next /goal (SLICE-1) is now v0.3.0-aware (dev Postgres compose, psycopg, Docker prerequisite in BOOTSTRAP.md).

Cut state after the tail: wiggleverse-ecomm main @ 0078b0c (no specs/); wiggleverse-ecomm-content main @ 235794c (SD-0001 v0.3.0, status graduated, single home); Feature #1 open with sizing notes; ecomm issue #3 and plugin issues #83/#84/#85 open. Next session: SLICE-1, per the stored /goal.
