feat(swap-service): record quote provenance for attribution ordering

[kaladinlight]

Description

registerSwapInService rebuilds the swap-service payload entirely from the stored quote, but the quote's own identity was never part of it — the quote id only reached the database inside the metadata JSON blob, and the quote's mint time was dropped altogether.

quotedAt is the time the quote backing a swap was minted, carried from public-api's stored quote (shapeshift/web#12621, merged).

It is deliberately not the row's createdAt. Registration always happens after the sell transaction is broadcast, so the two are not interchangeable and comparing a transaction against the wrong one inverts the result. For the same reason existing rows keep quotedAt = NULL rather than being backfilled from createdAt: the mint time was never persisted, and inventing one would give a row provenance it does not have. Consumers must read NULL as "unknown", never as "earliest".

Also adds the fields a resolver will write — attributionStatus, attributionResolvedAt, attributionDetails — and an index on sellTxHash. These are included now so the resolver does not need a second migration; Postgres will not let a later migration add an enum value and use it in the same transaction, so the values are settled up front. attributionResolvedAt is separate from updatedAt because status polling bumps updatedAt on every tick, so it cannot anchor a settlement hold.

The enum carries one value per action the payout path can take — PENDING don't pay yet, ACCEPTED pay once the hold elapses, REJECTED never pay, DISPUTED hold for review. Whether a row shares a sellTxHash with another is deliberately not a status: that is a count over sellTxHash, which the new index serves. None of these are on CreateSwapDto — attribution resolution is a server-side verdict, and accepting any part of it from a caller would defeat the point.

The quote's identity needs no column: public-api registers a swap under swapId = storedQuote.quoteId, so that association already exists on every api-origin row (verified: 25/25 prod, 79/79 staging).

Testing

• yarn workspace @shapeshift/swap-service test — 81 passing (77 before this change)
• Three new cases cover the round trip, the null-when-absent case, and two ways a bad timestamp is rejected: unparseable strings, and non-strings, since POST /swaps has no runtime validation and epoch millis would otherwise parse as a valid but wrong date
• Migration is additive — four nullable-or-defaulted columns and one index, no data rewrite. On Postgres 11+ the defaulted column is a metadata-only change
• Deploy note: public-api must ship before this, or new rows land with quotedAt = NULL. feat(public-api): drop the dead browser swap write, send quotedAt web#12621 is merged, so verify it is deployed first

📝 Walkthrough

Walkthrough

The swap schema now stores quote timestamps and attribution metadata. createSwap converts valid quotedAt strings to dates and stores null for invalid values. Tests and verification fixtures cover the new fields.

Changes

Quote provenance

Layer / File(s)	Summary
Swap attribution storage prisma/schema/swap-service.prisma, prisma/migrations/.../migration.sql	The Swap model and migration add quote timestamp, attribution status, resolution timestamp, details, enum values, defaults, and a sellTxHash index.
CreateSwap quote persistence packages/shared-types/src/index.ts, apps/swap-service/src/swaps/utils.ts, apps/swap-service/src/swaps/swaps.service.ts	CreateSwapDto accepts quotedAt. toQuotedAt returns a parsed Date for valid strings and null otherwise. createSwap persists the result.
Quote persistence validation apps/swap-service/src/swaps/__tests__/create-swap-attribution.test.ts, apps/swap-service/src/verification/__tests__/fixtures/*/swap.ts	Tests cover valid, absent, malformed, and non-string timestamps. Verification fixtures include the new quote and attribution fields.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 32ee2

This PR adds quote provenance and attribution fields plus a sellTxHash index. The regular index build can block new swap registrations during deployment, and the submitted quote timestamp is not independently tied to the originating quote, which could compromise future attribution ordering. Merge readiness therefore requires deployment handling for the index and explicit ownership of the provenance boundary.

I twitch my nose at quotes in flight
A date is saved when strings are right
Bad timestamps turn into null
Attribution fields stand tall
The swap record rests, neat and bright
