Two gaps from the first pass, both about a client that polls. Rate limiting is keyed by user rather than by IP. A self-hosted integration and its owner's browser routinely leave the same address, and an IP bucket would let one starve the other; 120 requests a minute is generous for a sync surface and still bounded, so a runaway poll degrades its own integration instead of the instance. updated_at now ships with every trip, and its docblock says plainly what it is not: a content timestamp. It moves when the trip's own fields change — title, dates, currency, cover — and stays put when a place, a day or a note is edited, because the child tables carry no updated_at of their own. That also rules out the ?since= filter this was meant to enable: it would silently hide every trip whose itinerary changed, which is worse than no filter at all. Making it honest needs a schema change, not an API field, so the field is documented for what it is and the filter is left out.
@trek/shared
Single source of truth for TREK's API contracts, expressed as Zod schemas and consumed by both the server (request validation + inferred DTO types) and the client (typed requests/responses).
This package is part of the incremental NestJS + React 19 migration (see the "Brownfield Rewrite" board). It is intentionally dormant until modules start importing it — adding it changes nothing for users.
Rules
- One folder per domain:
src/<domain>/<domain>.schema.ts(+.spec.ts). - Domain-agnostic building blocks live in
src/common/. - A route is only considered migrated once its contract lives here.
- Schemas are the source of truth; server DTOs and client types are inferred from them
(
z.infer<typeof schema>), never hand-duplicated.
Consumption (dev)
Both apps resolve @trek/shared to this package's TypeScript source:
- Server (
tsx): viapathsinserver/tsconfig.json. - Client (
vite): viaresolve.aliasinclient/vite.config.ts(+pathsfor the type-checker).
Production packaging (Docker / workspace wiring) is introduced in card F2, when the server first depends on this package at runtime. Until then prod builds are untouched.

The canonical error envelope is finalised in card F5 (it must match TREK's current Express error responses byte-for-byte), so it is deliberately not invented in F1.
