Adds GET/PUT /addons/vacay/year-settings and makes the reads window-aware, so the backend from the previous commit is actually reachable. Entries and shared calendars now load over the caller's window instead of a date prefix — a shifted year spans two calendar years and the prefix silently dropped the second half. Reads are month-aligned (the grid draws month cards), while entitlement stays day-exact; the two coincide for every window starting on the 1st, which is all of calendar. deleteYear clears entries per author over that author's period, and company holidays only over the range every member shares, so one member deleting a period cannot reach into another's live one. getStats reports the window it counted, and getOwnPlan seeds the period today falls into rather than the calendar year. A start day the month cannot have (Feb 29 from a hire date, a stored Feb 31) is clamped to one every year has — otherwise the boundary string matches no date and the whole window slides. Anniversary before a hire date is entered resolves to the calendar year instead of borrowing a month a previous fiscal setting left behind. MCP reads pass their user through; without one the range stays the plain calendar year, so plan-scoped callers 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.
