- propose_hike, create_hike and update_tour take stage_end on the stops a day ends at, checked by the tours' own stage rules (never at the start or the end, at most 60 stages) on REST and MCP alike. - A proposal over several days names its stage ends and sets no single day's schedule; its card counts the stages and marks the stops they end at. - New points for a hike in stages keep the keys of the stops they stand on, so a stage keeps its day; they are refused only where they would drop every stage end. - The tours group and the prompt name the stages, how to put each on its day, and what to offer once a tour is planned: places along it, its packing, the GPX file.
@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.
Not yet here
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.
