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.
createTestModule (tests/helpers/test-module.ts) builds a Nest testing module of the domain modules under test over the suite's test db, with a FakeRealtimeService and provider overrides for the collaborators a suite controls. bootTestApp (tests/helpers/test-app.ts) boots AppModule once per file, with recording realtime, fixture storage and an offline geocoder, and the MCP harness takes McpRegistryService from it inside a request context instead of hand-wiring roughly eighty services. The days, day removal and day notes service suites take their subjects from DaysModule and DayNotesModule.
