A screen reader lists a page's buttons together, and the costs views gave
it twenty "Edit" and "Delete" buttons with nothing to tell them apart.
- Edit and delete on an expense name the expense ("Edit: Dinner"), edit
and undo on a payment name who paid whom, on desktop and phone.
- A settle-up row shows only initials in its avatars, its names lived in a
tooltip; the row now carries them for assistive tech too, and its Settle
button says who pays whom and how much.
- The search field of every searchable select (currency, time zone,
category) was read out as "..."; it now says Search in the user's
language.
- The public link toggles on the phone share sheet and the journey share
toggles say whether they are on (aria-pressed), not only by colour.
- Japanese still said "you" in the settle-up lines.

@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.
