 /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`.
