First strangler migration (L1): /api/weather is served by a NestJS module.
- @trek/shared/weather Zod contract; Nest controller byte-identical to the legacy Express route (paths, query params, status codes, { error } bodies, lang default, ApiError/500 passthrough). Service reuses getWeather/getDetailedWeather (+ shared cache; MCP tools unchanged).
- Strangler routes /api/weather to Nest by default; the legacy Express route + its migration-time parity test were decommissioned in this PR.
- Frontend (FE2): weatherApi typed against the @trek/shared WeatherResult contract.
- Harness: reusable Nest-vs-Express parity harness, e2e harness (temp SQLite + seed/cookie helpers, real JwtAuthGuard), src/nest coverage gate raised to >=80%, src/nest test guide.
- Verified end-to-end on a prod mirror (dev1): 401/400/200 via Nest with real Open-Meteo data, Express route gone.

/**
|
|
* Shared e2e harness for migrated Nest modules.
|
|
*
|
|
* Gives each module e2e test a throwaway in-memory SQLite db (the same shape the
|
|
* shared connection exposes), a seed helper for demo data, and a session-cookie
|
|
* signer that produces tokens the REAL JwtAuthGuard accepts — so e2e tests cover
|
|
* the actual auth path end-to-end, not a stubbed guard.
|
|
*
|
|
* Wire it in a test with `vi.mock('../../src/db/database', () => ({ db, ... }))`
|
|
* using the db returned here, then build the Nest app under test.
