Three critical bugs fixed in correlation service:
Bug 1: Premature A event cleanup (CRITICAL)
- cleanExpired() was using system time instead of B event TTL
- A events now only removed when no valid B exists AND A age > TimeWindow
- New cleanBufferAByBTTL() method respects B event TTL
Bug 2: Flush emitting all A as orphans without correlation attempt
- Flush() now tries to correlate remaining A with remaining B first
- Only emits A as orphan if no matching B found
- Preserves correlation during shutdown
Bug 3: Buffer full causing immediate orphan emission
- Implemented FIFO rotation instead of immediate emission
- Oldest A event removed when buffer full, new event buffered
- New rotateOldestA() and rotateOldestB() helper methods
New tests added:
- TestCorrelationService_ALateThanB_WithinTimeWindow
- TestCorrelationService_ALateThanB_AExpiredTooSoon
- TestCorrelationService_Flush_CorrelatesRemainingEvents
- TestCorrelationService_BufferFull_RotatesOldestA
- TestCorrelationService_CleanA_RespectsBTTL
All 24 tests pass.
