feat(correlation): add configurable delay before emitting orphan A events
New feature: Apache events can now wait for B events before being emitted as orphans.
Changes:
- Add ApacheEmitDelayMs config (default: 500ms)
- Add pendingOrphans structure for delayed emission
- processSourceA(): add A to pending orphans instead of immediate emission
- processSourceB(): check pending orphans before buffer A
- emitPendingOrphans(): emit orphans after delay expires
- Flush(): emit all pending orphans immediately (shutdown)
Configuration:
correlation:
orphan_policy:
apache_always_emit: true
apache_emit_delay_ms: 500 # Wait 500ms before emitting as orphan
Backward compatibility:
- apache_emit_delay_ms: 0 → immediate emission (legacy mode)
- apache_emit_delay_ms < 0 → default 500ms
Tests added (5 new tests):
- TestCorrelationService_ApacheEmitDelay_BArrivesDuringDelay
- TestCorrelationService_ApacheEmitDelay_NoBArrives
- TestCorrelationService_ApacheEmitDelay_ZeroDelay
- TestCorrelationService_ApacheEmitDelay_MultipleA_SameKey
- TestCorrelationService_ApacheEmitDelay_Flush
All 30 tests pass. Coverage: 75.1%
