The day plan wrote straight to the API, so offline a place dropped on a day snapped back with "Error assigning place", a renamed day or a new day note failed, and a moved stop, a leg's travel mode or who joins a visit were lost. Visits (put on a day, taken off, reordered, moved, travellers, leg mode), the day's name, notes text and travel mode, and the day notes (add, edit, delete, move) now go through assignmentRepo, dayRepo and dayNoteRepo and the mutation queue: the cached day changes at once, a visit or note made offline gets a temporary id that the edits after it wait for, and an online write held behind an older queued one joins the queue, since none of these carry a version token. A new order of a day that names a visit made offline is sent with its real id, or without it when its create failed. Desktop, the phone timeline and note sheet all write through the store, so both are covered. The replay reads each answer for what it names: the day answer keeps the cached notes and visits, the participants answer lands on its visit, and a visit the server refuses with 409 (a Tour already on that day) fails instead of waiting as a conflict no retry can solve. The trip's name, description, reminder and the archive flag wait in the queue too, from the planner, the phone and the dashboard. What only the server can do says so instead of failing: new dates, a day count, a currency or a cover, a new trip, a copy or a delete, members, guests, share and invite links, and a new order of the days, which moves the dates of the bookings.

@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.
