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.

Replace the deprecated v3 string-method forms with the top-level
validator helpers zod 4 prefers:
- z.string().url() → z.url() (3 sites)
- z.string().uuid() → z.uuid() (5 sites)
- z.string().datetime() → z.iso.datetime() (9 sites)
Also swap the ZodIssueCode.custom compat-shim reference in
demo-bot.server.ts's superRefine for the bare string literal "custom",
which is v4's idiomatic form. No runtime change.
All 147 tests still pass.
The `parsed.error.issues.map(i => ({field, message}))` pattern in the
five journal API route handlers stays as-is — the fields we read are
unchanged in v4, and zod's new error helpers (z.treeifyError,
z.prettifyError) produce different shapes that would change our
public API error contract.
