Goal: an LLM or script can migrate an entire legacy database using only
the HTTP API - original history preserved, safely re-runnable.
- X-Import-Mode header (admin only): create/update endpoints across 15
timestamped entity types accept original createddate/modifieddate;
helper exposed via shopdb.api (contract 0.7.0 -> 0.8.0).
- Exact-match natural-key lookup filters on 13 list endpoints for the
lookup-then-upsert recipe.
- Selfhosted USB checkout/checkin accept backdated event times in
import mode.
- docs/IMPORT-API.md: operator manual grounded in the real legacy
schema - order of operations, full table-by-table mapping including
the machines fan-out, idempotent Python importer with dry-run, parity
checks, and decided dispositions for unmigrated tables (DNC config
stays live-fed via the collector; supportteams/appowners map to the
upcoming supportteams model).
635 tests pass; naming green; frontend untouched.
