BudgetPanel titled its add button with budget.addCategory (since April) and the trip form labelled its cover remove button with common.remove (since August). Neither key was ever in en, and t() returns an unknown key unchanged, so both rendered as the raw key in every language. Both are added to all 27 locales. Locale parity compares the locales with en, never en with the code, so nothing could catch this. client/scripts/i18n-keys.mjs (npm run lint:i18n-keys) now resolves every literal key src/ names against en: the first argument of t(), tHtml() and tr() (both sides of a conditional included), <TransHtml html>, the fallback of translateApiError and any *Key property or prop. A template key, a prefix with the rest appended and the help registry's key builders pass when their fixed parts match an en key; the one template with no fixed part is on an allow-list that names the keys it resolves to, and an entry nothing uses fails. With --unused it lists the en keys nothing reaches, as information only. en is read with shared/scripts/i18n-catalog.mjs, a reader for the locale tables as text that the parity tooling will share. It refuses a value that is not one string literal instead of skipping the key.
@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.
