Maurice 8dacd0a50c fix(book): the auto layout's drawn templates no longer carry photos of the book they were drawn in
Three photo frames in the templates kept the photo ids of the journey the
templates were read out of (68 and 69). Only empty frames take an entry's
photos, so every book laid out on those templates pointed at those ids: a
broken picture on most installs, and on one where the id exists, someone
else's photo or an unrelated one of the user's own. The frames are empty
now and take the entry's photos like the others. The parity digests of the
five spreads that use them are written anew, as the spec asks for a
deliberate layout change.

@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): via paths in server/tsconfig.json.
  • Client (vite): via resolve.alias in client/vite.config.ts (+ paths for 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.
