# AGENTS.md

## Agent context

Read this file, `docs/CAPTURE.md`, and `docs/PHOTOS.md`.
Implement Milestone 2 only. Specification: `docs/PHOTOS.md`.
PRD: `docs/PRODUCT.md` for destination and field names. Do not implement Milestone 3 or 4.
Do not widen Milestone 2 into Complete-listing taxonomy, SKU, price, copy, or Woo create.

## Milestone 2

Photos.
Acceptance: on a phone, batch of 1–N photos, user-picked calibration photo through Milestone 1 mask/axis/measure, every successful shot as a 3:4 transparent inventory PNG lined up, Milestone 1 numbers on screen, dimension-overlay copy of the calibration PNG present.

Milestone 2 is inference-free. Batch mask/crop reuse and dimension overlays run in the browser as ordinary code. There is no inference URL and no model call in this milestone.

## Milestone 1 (historical)

Capture. Spec: `docs/CAPTURE.md`. Remains the calibration math and PNG contract Milestone 2 reuses.

## Invariants

- Quantity per listing is one.
- User enters length, thickness, and SKU.
- App proposes remaining listing fields. User reviews before create.
- Non-math fields remain editable until create.
- `bdft = sqft × thickness_in`
- Price proposal is `bdft × species $/bdft`. User may replace it. Missing rate leaves price empty.
- User-entered length, thickness, SKU, price, and taxonomy override computed or inferred values.
- SKUs matching `SLAB-UAT-*` create as Woo draft.
- Create works with inference off.
- Source below the PNG size floor requires a new photo.
- Existing store SKU blocks create.
- Dimension overlay orientation follows the user-approved length axis from Milestone 1.
