The head card read LEAVE 11:30 over a chain whose first stop is pinned at 10:00 with an hour and a half there. The figure was the departure from the first stop, a clock no row prints, while ARRIVE was the last stop's arrival. So the number was the wrong quantity and "Leave" the wrong word for it. Both figures now come off the arrival column the rows print: START is the first timed arrival (or the resume point on a morning after an automatic night), ARRIVE is the last one. The rule lives in stageClocks in the shared row model and reaches the tab as rt.clocks. The label is a new key, mobileTrip.rtStart, because roadtrip.stay.leave keeps meaning a stop's own departure in the stop and stay sheets. Both clocks carry dir=ltr like the rows.
@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.
