Travel wires in
Phase 4 of the Real-World Knowledge Platform epic. TravelPlatform — transport search, accommodation, bookings — wired into the @McpDomain surface through ConnectorTravelApi. Eleven endpoints covering all four capabilities: TransportSearch, TransportBooking, AccommodationSearch, AccommodationBooking.
The interesting thing about this one is what it didn’t require. Commerce (#162) established the wiring pattern two days ago. Travel is the fourth platform to follow it (after contacts, project, and commerce). By now the pattern is mechanical: capability-gated API class, requireCapability with UnsupportedCapabilityException, connectorsReport integration, CDI wiring through GraphqlBeans, and the test structure — stub with boolean capability flags, full stub with inline implementations, unsupported-throws and happy-path-delegates.
The one wrinkle was Java records and interface method name collisions. TravelPlatform has a transportSearch() accessor that returns a TransportSearch capability interface. If you name a record component transportSearch (the boolean flag), the record’s auto-generated accessor clashes with the interface method. Commerce didn’t hit this because its capability names (ProductSearch, Cart, Checkout) don’t overlap with method names on CommercePlatform. The fix was trivial — shorter component names — but it’s the kind of thing that only surfaces at compile time.
Nine platforms now report through connectorsReport (chat, calendar, bank, email, document, contacts, project, commerce, travel). Location is the tenth SPI but hasn’t been wired into the report yet. The ALL_SCOPES set has nine entries; CLAUDE.md’s “10 platforms” count includes location. That’ll be a separate issue.
The pattern maturity is the story here. When we built the first @McpDomain API (chat), the shape wasn’t obvious — capability introspection, user-scoped accessors, the requireCapability helper, the test stub taxonomy. By Phase 4, it’s a template. The next platform SPI wiring should take the same shape with no design decisions at all.
