* feat(dayplan): persist per-leg and per-day travel mode (#1281) The day-plan route used one transport mode for the whole day, held only in ephemeral state. Store it instead: leg_transport_mode on an assignment is the mode of the leg leaving that stop (null = inherit the day default), and days gains a default_transport_mode. Both nullable, so existing itineraries are unchanged. Adds PUT /assignments/:id/transport and PUT /days/:id/transport — their own endpoints so setting the day default can't wipe notes/title the way the general day update would — mirroring the assignment_time path. * feat(dayplan): choose the travel mode per segment (#1281) Each leg between two stops now routes with its own mode, so a day can mix walking, driving and plugin-routed legs. Tap the connector between two places to change that leg's mode (desktop popup / mobile sheet); the whole-day Foot/Car picker sets the persisted day default and leaves explicitly-set legs alone. The connector and map redraw in the chosen mode, and each route segment is tagged with the mode it was drawn in. New strings across all 23 locales.
@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.
