| 35 |
* writes (guardrail G1), the server half of the client push path. Registered at |
| 36 |
* `POST /{API_NAMESPACE}/push/{collection}`; it dispatches on the envelope's |
| 37 |
* `operation` (not the HTTP verb — the client always POSTs the envelope) and |
| 38 |
* applies each create/update/delete through the collection's Woo write seam: |
| 39 |
* every collection forwards to its `wc/v3` controller, including the nested, |
| 40 |
* parent-aware variation routes. The generic identity, lock, CAS and ack pipeline |
| 41 |
* remains shared across every collection. |
| 42 |
* |
| 43 |
* Identity is the client uuid (DECIDED): the server resolves the record by its |
| 44 |
* `_woocommerce_pos_uuid`, reuses it, and NEVER re-keys. Idempotency + resolution |
| 45 |
* live in an injected mutation store, so the apply logic is unit-testable with a |
| 46 |
* fake store + a stubbed `rest_do_request`. |
