Records every monetary movement in the marketplace: buyer pay-ins, seller payouts, and refunds. The current model is centered on Request Network pay-in, in-house checkout metadata, on-chain transaction verification, escrow state, and provider request IDs. The `provider` and `direction` discriminators let one collection hold incoming buyer payments, outgoing seller releases, refunds, and legacy/other provider records.
> [!warning] Runtime store
> The `Payment` document is still created, read, and updated through Mongoose on normal request paths. Backend `2.6.80` can persist oracle quotes to Postgres `payment_quotes`, but that is conditional on `ORACLE_QUOTING_ENABLED=true` and does not make the whole payment domain PG-authoritative. See [[Postgres Runtime Cutover Status]].

## Postgres Quote Table
The Postgres money-core branch stores oracle quotes in `payment_quotes`, a 1:1 child table keyed by `payment_id → payments.id`. Amount/rate columns use `numeric(38,18)` and the route resolves the PG parent through `payments.legacy_object_id` or `id_map` during the Mongo/PG dual-write window. If the PG payment row is missing, the quote is mirrored to this Mongo `quote` subdocument and a `pg_dualwrite_gaps` row is recorded for reconciliation.
