One remaining quantity per batch, kept in ApiCore and always derived:
initial quantity (jarCount / produced quantity) plus the signed movements
in the new BatchMovement ledger, which is never deleted.
- Production batches for MANUFACTURED articles (candles, propolis
products, ...); articles get a kind and a shop category.
- Withdrawals (farm shop, own use, breakage, sample) and inventory
corrections on bottlings and production batches, never more than the
remaining stock; every write locks the bottling or the article row.
- Shop bookings via POST /shop-sync/movements (new scope
shop-sync:write): idempotent per externalId, articles allocated oldest
best-before first, returns mirrored onto the batches of the sale,
invalid entries rejected one by one.
- GET /shop-sync/stock and remainingCount in the shop feed; webhook
stock.changed after every change (ids only, receivers fetch numbers).
- Bottlings and production batches with movements cannot be deleted.
