A third scope, home, next to trip and journey: threads that name neither a trip nor a journey (the CHECK now only forbids both), reached under /api/assistant by their owner only. A home turn reads the user's trips through list_trips into a short card (under way, next, later, behind, undated), offers every read (a trip's on the id the model names, checked by the tool with the user's rights) and only the writes that take no trip or journey (atlas, vacation planner, collections, tour library, settings), all held as change cards. open_trip_chat answers with a card that goes on in that trip's own chat with the question waiting in its composer. On the desktop the window opens on the home chat outside a trip; its head lists the trips to switch into and a switched trip chat has the way back. On the phone the home chat opens full screen from the dashboard head and the dock's More list, and the card opens the trip with its chat. Both run on useAssistantHome.
@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.
