## Launch prompt

`/goal SLICE-8` — Shopify dialect (closes Products story #13), per SD-0002 §7.2.

## Plan

> Anchor: design `wiggleverse-ecomm-content/specs/SD-0002-products-bulk-csv-import-export.md` (R2a, ELIGIBLE) — SLICE-8 §7.2; closes story #13.
> Posture: autonomous (yolo)

**SLICE-8 — Shopify dialect + public format docs → completes PUC-6, PUC-11**

Ships (per SD-0002 §6.5.1 / §7.2):
1. **Header-set dialect detection** — `detect_dialect()` recognizes Shopify's
   exact header set → `"shopify"`, else `"canonical"`; honest fail to canonical
   (never misparse) per §7.4 risk row.
2. **Shopify→canonical mapping** at the codec boundary (INV-17): rename Shopify
   headers to canonical before the known/unknown split; Shopify columns with no
   canonical home are reported as **not-imported** (the `unknown_columns`
   warning). Exhaustive mapping pinned as a fixture (§6.5.1).
3. **Preview UI** — "Shopify product CSV — mapped" banner + not-imported
   columns warning band on ImportPreview (PUC-6).
4. **DOC-2** — CSV column reference (every column; dialect notes), app-served,
   source in framework repo.
5. **DOC-3** — finalize `sample.csv` (variants + images worked examples) +
   link from import screen (PUC-11).
6. **E2E** `e2e_import_shopify_dialect` — unmodified Shopify fixture → mapped
   banner + not-imported warnings → confirm → run completes (DoD).
7. Unit tests (detection, mapping table, INV-10 partial-never-deletes over
   Shopify); §12 traceability audit; DOC-4 dialect-adapter notes; version bump;
   PPE deploy + E2E green; close #13.

## 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._
