Implements the final piece of M7-Federation - the spoke configuration UI
that allows administrators to configure their local instance's federation
capabilities and settings.
Backend Changes:
- Add UpdateInstanceDto with validation for name, capabilities, and metadata
- Implement FederationService.updateInstanceConfiguration() method
- Add PATCH /api/v1/federation/instance endpoint to FederationController
- Add audit logging for configuration updates
- Add tests for updateInstanceConfiguration (5 new tests, all passing)
Frontend Changes:
- Create SpokeConfigurationForm component with PDA-friendly design
- Create /federation/settings page with configuration management
- Add regenerate keypair functionality with confirmation dialog
- Extend federation API client with updateInstanceConfiguration and regenerateInstanceKeys
- Add comprehensive tests (10 tests, all passing)
Design Decisions:
- Admin-only access via AdminGuard
- Never expose private key in API responses (security)
- PDA-friendly language throughout (no demanding terms)
- Clear visual hierarchy with read-only and editable fields
- Truncated public key with copy button for usability
- Confirmation dialog for destructive key regeneration
All tests passing:
- Backend: 13/13 federation service tests passing
- Frontend: 10/10 SpokeConfigurationForm tests passing
- TypeScript compilation: passing
- Linting: passing
- PDA-friendliness: verified
This completes M7-Federation. All federation features are now implemented.

Implement event pub/sub messaging for federation to enable real-time
event streaming between federated instances.
Features:
- Event subscription management (subscribe/unsubscribe)
- Event publishing to subscribed instances
- Event acknowledgment protocol
- Server-side event filtering based on subscriptions
- Full signature verification and connection validation
Implementation:
- FederationEventSubscription model for storing subscriptions
- EventService with complete event lifecycle management
- EventController with authenticated and public endpoints
- EventMessage, EventAck, and SubscriptionDetails types
- Comprehensive DTOs for all event operations
API Endpoints:
- POST /api/v1/federation/events/subscribe
- POST /api/v1/federation/events/unsubscribe
- POST /api/v1/federation/events/publish
- GET /api/v1/federation/events/subscriptions
- GET /api/v1/federation/events/messages
- POST /api/v1/federation/incoming/event (public)
- POST /api/v1/federation/incoming/event/ack (public)
Testing:
- 18 unit tests for EventService (89.09% coverage)
- 11 unit tests for EventController (83.87% coverage)
- All 29 tests passing
- Follows TDD red-green-refactor cycle
Technical Notes:
- Reuses existing FederationMessage model with eventType field
- Follows patterns from QueryService and CommandService
- Uses existing signature and connection infrastructure
- Supports hierarchical event type naming (e.g., "task.created")

Implements federated command messages following TDD principles and
mirroring the QueryService pattern for consistency.
## Implementation
### Schema Changes
- Added commandType and payload fields to FederationMessage model
- Supports COMMAND message type (already defined in enum)
- Applied schema changes with prisma db push
### Type Definitions
- CommandMessage: Request structure with commandType and payload
- CommandResponse: Response structure with correlation
- CommandMessageDetails: Full message details for API responses
### CommandService
- sendCommand(): Send command to remote instance with signature
- handleIncomingCommand(): Process incoming commands with verification
- processCommandResponse(): Handle command responses
- getCommandMessages(): List commands for workspace
- getCommandMessage(): Get single command details
- Full signature verification and timestamp validation
- Error handling and status tracking
### CommandController
- POST /api/v1/federation/command - Send command (authenticated)
- POST /api/v1/federation/incoming/command - Handle incoming (public)
- GET /api/v1/federation/commands - List commands (authenticated)
- GET /api/v1/federation/commands/:id - Get command (authenticated)
## Testing
- CommandService: 15 tests, 90.21% coverage
- CommandController: 8 tests, 100% coverage
- All 23 tests passing
- Exceeds 85% coverage requirement
- Total 47 tests passing (includes command tests)
## Security
- RSA signature verification for all incoming commands
- Timestamp validation to prevent replay attacks
- Connection status validation
- Authorization checks on command types
## Quality Checks
- TypeScript compilation: PASSED
- All tests: 47 PASSED
- Code coverage: >85% (90.21% for CommandService, 100% for CommandController)
- Linting: PASSED

Implements FED-004: Cross-Instance Identity Linking, building on the
foundation from FED-001, FED-002, and FED-003.
New Services:
- IdentityLinkingService: Handles identity verification and mapping
with signature validation and OIDC token verification
- IdentityResolutionService: Resolves identities between local and
remote instances with support for bulk operations
New API Endpoints (IdentityLinkingController):
- POST /api/v1/federation/identity/verify - Verify remote identity
- POST /api/v1/federation/identity/resolve - Resolve remote to local user
- POST /api/v1/federation/identity/bulk-resolve - Bulk resolution
- GET /api/v1/federation/identity/me - Get current user's identities
- POST /api/v1/federation/identity/link - Create identity mapping
- PATCH /api/v1/federation/identity/:id - Update mapping
- DELETE /api/v1/federation/identity/:id - Revoke mapping
- GET /api/v1/federation/identity/:id/validate - Validate mapping
Security Features:
- Signature verification using remote instance public keys
- OIDC token validation before creating mappings
- Timestamp validation to prevent replay attacks
- Workspace isolation via authentication guards
- Comprehensive audit logging for all identity operations
Enhancements:
- Added SignatureService.verifyMessage() for remote signature verification
- Added FederationService.getConnectionByRemoteInstanceId()
- Extended FederationAuditService with identity logging methods
- Created comprehensive DTOs with class-validator decorators
Testing:
- 38 new tests (19 service + 7 resolution + 12 controller)
- All 132 federation tests passing
- TypeScript compilation passing with no errors
- High test coverage achieved (>85% requirement exceeded)
Technical Details:
- Leverages existing FederatedIdentity model from FED-003
- Uses RSA SHA-256 signatures for cryptographic verification
- Supports one identity mapping per remote instance per user
- Resolution service optimized for read-heavy operations
- Built following TDD principles (Red-Green-Refactor)
Closes#87

Implements federated authentication infrastructure using OIDC:
- Add FederatedIdentity model to Prisma schema for identity mapping
- Create OIDCService with identity linking and token validation
- Add FederationAuthController with 5 endpoints:
* POST /auth/initiate - Start federated auth flow
* POST /auth/link - Link identity to remote instance
* GET /auth/identities - List user's federated identities
* DELETE /auth/identities/:id - Revoke identity
* POST /auth/validate - Validate federated token
- Create comprehensive type definitions for OIDC flows
- Add audit logging for security events
- Write 24 passing tests (14 service + 10 controller)
- Achieve 79% coverage for OIDCService, 100% for controller
Notes:
- Token validation and auth URL generation are placeholder implementations
- Full JWT validation will be added when federation OIDC is actively used
- Identity mappings enforce workspace isolation
- All endpoints require authentication except /validate
