The default mock return value for updateMany was missing from beforeEach,
causing tests to fail when the service called updateMany and checked count.

Added explicit tests to verify HTTP timeout protection against DoS attacks.
The 10-second timeout was already configured in FederationModule via
HttpModule.register({ timeout: 10000 }), preventing slowloris and resource
exhaustion attacks.
Changes:
- Added http-timeout.spec.ts with 4 tests verifying timeout configuration
- Verified all federation HTTP requests use configured HttpService
- Documented timeout configuration in scratchpad
- All services (command, query, event, connection, agent) protected
Verification:
- command.service.ts:100 uses httpService.post with timeout
- query.service.ts:100 uses httpService.post with timeout
- event.service.ts:185 uses httpService.post with timeout
- connection.service.ts:76,341 uses httpService with timeout
- federation-agent.service.ts uses httpService with timeout
Impact:
- No security vulnerability - timeout already configured
- Added verification tests to ensure timeout remains in place
- All HTTP requests protected against slowloris DoS attacks
- 4/4 new tests pass

Replaced broad try-catch blocks with targeted error handling that only
catches expected business logic errors (CommandProcessingError subclasses).
System errors (OOM, DB failures, network issues) now propagate correctly
for proper debugging and monitoring.
Changes:
- Created CommandProcessingError hierarchy for business logic errors
- UnknownCommandTypeError for invalid command types
- AgentCommandError for orchestrator communication failures
- InvalidCommandPayloadError for payload validation
- Updated command.service.ts to only catch CommandProcessingError
- Updated federation-agent.service.ts to throw appropriate error types
- Added comprehensive tests for both business and system error scenarios
- System errors now include structured logging with context
- All 286 federation tests pass
Impact:
- Debugging is now possible for system failures
- System errors properly trigger monitoring/alerting
- Business logic errors handled gracefully with error responses
- No more masking of critical issues like OOM or DB failures
Fixes#281

Implemented comprehensive audit logging for all incoming federation
connection attempts to provide visibility and security monitoring.
Changes:
- Added logIncomingConnectionAttempt() to FederationAuditService
- Added logIncomingConnectionCreated() to FederationAuditService
- Added logIncomingConnectionRejected() to FederationAuditService
- Injected FederationAuditService into ConnectionService
- Updated handleIncomingConnectionRequest() to log all connection events
Audit logging captures:
- All incoming connection attempts with remote instance details
- Successful connection creations with connection ID
- Rejected connections with failure reason and error details
- Workspace ID for all events (security compliance)
- All events marked as securityEvent: true
Testing:
- Added 3 new tests for audit logging verification
- All 24 connection service tests passing
- Quality gates: lint, typecheck, build all passing
Security Impact:
- Provides visibility into all incoming connection attempts
- Enables security monitoring and threat detection
- Audit trail for compliance requirements
- Foundation for future authorization controls
Note: This implements Phase 1 (audit logging) of issue #276.
Full authorization (allowlist/denylist, admin approval) will be
implemented in a follow-up issue requiring schema changes.
Fixes#276

but success was returned to the user, leaving zombie connections in
PENDING state forever.
Changes:
- Delete failed connection from database when HTTP request fails
- Throw BadRequestException with clear error message
- Added test to verify connection deletion and exception throwing
- Import BadRequestException in connection.service.ts
User Impact:
- Users now receive immediate feedback when connection initiation fails
- No more zombie connections stuck in PENDING state
- Clear error messages indicate the reason for failure
Testing:
- Added test case: "should delete connection and throw error if request fails"
- All 21 connection service tests passing
- Quality gates: lint, typecheck, build all passing

Replaced placeholder OIDC token validation with real JWT verification
using the jose library. This fixes a critical authentication bypass
vulnerability where any attacker could impersonate any user on
federated instances.
Security Impact:
- FIXED: Complete authentication bypass (always returned valid:false)
- ADDED: JWT signature verification using HS256
- ADDED: Claim validation (iss, aud, exp, nbf, iat, sub)
- ADDED: Specific error handling for each failure type
- ADDED: 8 comprehensive security tests
Implementation:
- Made validateToken async (returns Promise)
- Added jose library integration for JWT verification
- Updated all callers to await async validation
- Fixed controller tests to use mockResolvedValue
Test Results:
- Federation tests: 229/229 passing ✅
- TypeScript: 0 errors ✅
- Lint: 0 errors ✅

Changes:
- Added version field to RunnerJob schema for optimistic locking
- Created migration 20260202_add_runner_job_version_for_concurrency
- Implemented ConcurrentUpdateException for conflict detection
- Updated RunnerJobsService methods with optimistic locking:
* updateStatus() - with version checking and retry logic
* updateProgress() - with version checking and retry logic
* cancel() - with version checking and retry logic
- Updated CoordinatorIntegrationService with SELECT FOR UPDATE:
* updateJobStatus() - transaction with row locking
* completeJob() - transaction with row locking

- Lost progress updates
- Invalid status transitions
- Data corruption under concurrent access

- Classify errors as retryable vs non-retryable
- Handle transient errors gracefully with retry logic
- Support Last-Event-ID header in controller for automatic reconnection
Files modified:

Add composite index [jobId, timestamp] to improve query performance
for the most common job_events access patterns.
Changes:
- Add @@index([jobId, timestamp]) to JobEvent model in schema.prisma
- Create migration 20260202122655_add_job_events_composite_index
- Add performance tests to validate index effectiveness
- Document index design rationale in scratchpad
- Fix lint errors in api-key.guard, herald.service, runner-jobs.service
Rationale:
The composite index [jobId, timestamp] optimizes the dominant query
pattern used across all services:
- JobEventsService.getEventsByJobId (WHERE jobId, ORDER BY timestamp)
- RunnerJobsService.streamEvents (WHERE jobId + timestamp range)
- RunnerJobsService.findOne (implicit jobId filter + timestamp order)
This index provides:
- Fast filtering by jobId (highly selective)
- Efficient timestamp-based ordering
- Optimal support for timestamp range queries
- Backward compatibility with jobId-only queries
