# Milestone 3 — Create

Builds on Milestones 1–2 (`docs/CAPTURE.md`, `docs/PHOTOS.md`).
Destination and field names also live in `docs/PRODUCT.md`.

**Scope source of truth:** this file and the Ty conversations that wrote it.
Task and milestone breakdowns on `main` (including older PRODUCT / IMPL-PLAN / CONTENT-WOO splits) are **obsolete for M3**. Do not cross-reference `main` for what M3 includes once this branch is the working set.

## Goal

Phone path from Photos-ready device draft → store-synced **Woo attributes** filled and reviewed → WooCommerce product create (practice SKUs as draft) → clear device draft.

M3 also wires the **OpenAI-compatible inference endpoint** as a server dependency so inference ops can run when enabled. Create must still work with inference off.

## Woo attributes

Locked name for the synced taxonomy package. WooCommerce is the source of truth; the app caches ids and never invents the lists.

### Categories (product categories, leaf-only)

| Field | Cardinality | Notes |
|---|---|---|
| Species | exactly 1 required | Synced species leaves only; no hardcoded / fallback set |
| Wood category | 1+ required | Parents are grouping only; picks are leaves |

### Attributes (exactly five locked Woo attributes)

| Attribute | Cardinality | Notes |
|---|---|---|
| Edge Type | 1 required | Term id from sync |
| Figure | 1+ required | Term ids from sync |
| Grade | 1+ required | Term ids from sync |
| Thickness | 1 required | Measured thickness rounded **up** into the store band |
| Moisture | 1 required | Default kiln-dried; user sets/keeps; **never inferred** |

v1: missing attributes are skipped, not created. Species, character, length, and free-text thickness are **not** product attributes.

### Tags

| Tag prefix | Cardinality | Notes |
|---|---|---|
| `fig-*` | 1+ required | Other Woo tags ignored |
| `feat-*` | 0+ optional | Character / inclusions / voids / checks map onto existing feat tags only |

### Listing facts beside taxonomy

- User: SKU, length, thickness (and app-computed widths / sqft / bdft from M1/M2)
- Price: propose `bdft × species $/bdft` from pricing rules; user may override; missing rate → empty price
- Copy: title / short title / description from templates (optional Generate text when inference is on; not required for ready)

## Sync (Woo)

- FastAPI is the sole Woo client. Credentials never in the browser.
- Auth: WordPress **application password** for a dedicated low-privilege WP user (not Woo `ck_`/`cs_` consumer keys).
- Store URL: `WOO_BASE_URL` from `deploy/.env` / compose (`https://` only). Settings shows it read-only. Not a SQLite settings row.
- Woo username + application password: Settings UI → AES-GCM in SQLite (`SLAB_AES_KEY` env).
- Taxonomy sync pulls, in order: categories → tags (`fig-*` / `feat-*` only) → attributes + terms (five locked).
- Sync failure keeps the previous cache (never delete-then-fail). Stale picks show “no longer valid”; never silently swap.

## Inference dependency

- OpenAI-compatible endpoint: `inference_base_url`, API key, model in **Settings** (encrypted), not compose env.
- Server proxies all inference calls.
- Feature-flagged. **Create / ready path must pass with inference off** (manual taxonomy + deterministic numbers + Woo draft).
- Vision may prefill taxonomy at ≥0.7 confidence when on; typed values always win; below threshold → leave empty.

## Ready set (submission ready)

Review does not continue until the full ready set is filled. Species + one figure is not enough.

Required:

- ≥1 inventory PNG (from M2)
- SKU, length, thickness; widths / sqft / bdft present
- Species, ≥1 wood category, edge type, ≥1 figure, ≥1 grade, thickness band, moisture, ≥1 `fig-*`, price
- `feat-*` optional (0+)

## Create

- `POST` product to Woo with categories, attributes, tags, price, copy, inventory PNG images.
- Duplicate SKU (any store status) blocks create; no update path in this version.
- `SLAB-UAT-*` always creates as Woo **draft**, even if Settings say publish.
- Device draft ≠ Woo draft. After successful create, clear the device draft.
- Default create status from Settings `woo_create_status` (`draft` \| `publish`, default `draft`), subject to the UAT force-draft rule.

## Acceptance (done when)

Product state induced: overnight UAT app on ubudual5060 `http://100.64.0.9:10881` (or the current M3 deploy of this branch), with Woo credentials and `WOO_BASE_URL` pointed at the intended store.

Evidence from that state:

1. Taxonomy sync via application password retrieves Woo attributes into the app cache; pickers offer only synced ids.
2. A Photos-ready slab can be filled to the full ready set using those synced lists (inference off is a required path).
3. Create with `SLAB-UAT-*` yields a WooCommerce **draft** product whose categories / attributes / tags / price / images match the reviewed ready set.
4. Duplicate SKU is blocked; device draft clears after success.
5. Inference Settings accept an OpenAI-compatible base URL / key / model; create still succeeds with inference disabled.

## Dishonest proxies (do not count as pass)

- Hardcoded or fixture taxonomy lists treated as “synced”
- Mock Woo client or in-process fake that never hit the real store
- Claiming ready / create green from unit tests alone without a real draft in the store
- Consumer-key auth instead of application password
- Inference “wired” only as dead config with no server proxy path, or create that requires inference on
- Touching `:10880` (Ty Node/SvelteKit) or dumping work onto `m2-ds` / doc-simplification branches

## Out of scope (unless Ty expands M3 in chat)

- Full Assist UX beyond the OpenAI endpoint dependency and optional prefill rules above
- Creating new Woo attributes / terms / tags from the app
- Update-in-place of an existing store SKU
- Bulk create
