- Found places: the strip shows only when the answer names one of them, the named ones first. A click on a card, or "Add to trip", opens the planner's place form filled in with the place on the day in focus, its Google details (photos, hours, description) loading beside it; "+ Day" and the day grid are gone. - Trip notes: remember_for_trip runs at once without a card. The assistant keeps lasting facts the user mentions (who travels, needs, likes, budget, pace) on its own and offers the unsure ones as a follow-up; the chat shows "Noted for this trip: ..." with the notes a tap away, and reads them again so the dialog never saves over the new note. - City walks: set_city_walk_visit checks a station off on its day (visited, skipped, or the mark taken back), with day_edit as in the day plan, a change card naming the station and its walk, and an undo that restores the status before while the station is as the change left it. - Card heads are a step smaller (32px tile, smaller title and count), and the dot beside "Working on it" in the header is gone.
@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.
