Two holes let English through the ratchet unseen.
A plural form en has no key for (Russian .few and .many, Arabic .two)
was compared with en's value for that same key, which never exists, so a
locale could copy en's text into exactly the forms a new plural group
needs and the count stayed put. Such a form is now compared with every
form en spells out for the group. A form en does declare keeps the exact
comparison: Italian "{count} file" is the Italian plural, not a copy of
en's "{count} file".
The // same-as-en marker excused any value in a Latin-script locale, so
one comment waved a whole copied sentence through. It is honoured only
on a value holding a single plain word, the case shared/CLAUDE.md
already describes. No locale carries the marker today, so nothing that
passed before fails now; the counts are unchanged.
@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.
