Route and Activity existed three times: hand-written interfaces in
packages/types, Zod contracts in packages/api, and Drizzle columns in
packages/db — each with different fields and nullability. The
hand-written ones had drifted so far they had zero importers; the Zod
contracts were advisory because v1 handlers hand-rolled Response.json
shapes nothing validated.
- packages/types keeps only what both apps actually share (Waypoint,
WaypointPoiTags) and documents where row types and wire contracts
live; the dead Route/RouteMetadata/RouteVersion/Activity interfaces
are gone
- packages/db exports canonical inferred row types (RouteRow,
ActivityRow, RouteVersionRow, UserRow)
- packages/api contracts are reconciled with the real wire format
(RouteVersionSchema gains the id and createdBy fields the endpoint
has always returned) and gain Create*ResponseSchemas
- apiJson(schema, payload) in api-guard parses every v1 response
through its contract: drift is now a thrown ZodError in tests/CI,
unknown keys are stripped, and payloads are compile-checked as
z.input of the schema
Enforcement immediately caught two real drifts: nullable DB
descriptions could ship null where the contract promises string (now
coalesced at the boundary), and GET /api/v1/activities/:id was missing
the routeName and photos fields its contract declares.
