bootTestApp replaced JourneyPhotoCaptureService with a factory calling its constructor positionally, only to hand it an offline geocoder, so a dependency the service gained broke the boot of every MCP suite. The container now builds the service itself and the OsmClient's reverse lookup answers that nothing is known, which also keeps every other reverse lookup a booted suite reaches inside the process.

/**
|
|
* The whole application container, booted once per test file for suites that
|
|
* drive a cross-domain surface (the MCP tools, the plugin RPC host) rather
|
|
* than one domain.
|
|
*
|
|
* It is AppModule itself, over the `src/db/database` handle the suite mocks
|
|
* with a snapshot db, so every service, controller and discovery registry is
|
|
* the one production builds. Suites used to rebuild that graph by hand with
|
|
* positional constructor calls, which every new dependency broke; now a
|
|
* dependency a service gains reaches these suites through its module.
|
|
*
|
|
* What the container would otherwise reach outside the process is replaced,
|
|
* the same stand-ins the hand-built graphs used:
|
|
* - RealtimeService: the suite's FakeRealtimeService (or a fresh one), so
|
|
* broadcasts are recorded instead of delivered;
|
|
* - the reverse geocoding OsmClient sends to Nominatim (the journey photo
|
|
* capture asks it for every attached provider photo): it answers that
|
|
* nothing is known. The instance's method is replaced after the build, so
|
|
* the container wires every consumer itself and a spy a suite sets on
|
|
* MapsService.prototype.reverseGeocode still wins;
|
|
* - StorageService: a real local driver in a throwaway directory
|
|
* (makeStorageFixture), so nothing a suite uploads lands in server/uploads.
|
|
*
|
|
* The container is built on the first call and handed out again for the same
|
|
* RealtimeService, so a suite that opens a harness per case boots once. Lifecycle
|
|
* hooks run (discovery fills the MCP and plugin registries in onModuleInit);
|
|
* the HTTP server and the websocket gateway are never bound, since no app is
|
|
* created on top of the module.
