Security alert prompts: preserve event provenance and time

Operational case

Orion Fleet receives 47 alert records from identity, endpoint, and network sensors. Identity event I-47 occurred at 09:14 but arrived at 09:23 after a network event from 09:19. Sorting by arrival would invert the sequence. The intake converts both to a common time basis and retains each sensor's raw value. One endpoint record lacks a host identifier; it goes to an unresolved bucket and is not attached to the nearest named host simply because the timestamps are close.

I-47 | identity | event 09:14 | ingested 09:23 | host H-47
N-51 | network | event 09:19 | ingested 09:20 | host H-47
E-09 | endpoint | host missing -> unresolved
Order by event time; retain source IDs and raw times

Performance and review cost

Parsing and validating N alerts is O(N); sorting their event times is O(N log N). Carrying source pointers adds little space beside the records and saves investigation time when summaries disagree. A sensor clock may be wrong, so the normalized order is a working hypothesis until clock health is checked. The prompt should expose that uncertainty instead of presenting millisecond precision as certainty.

Common Mistakes

• Do not order events by ingestion time alone.
• Do not attach an alert to a host without a supported identity key.
• Do not discard raw sensor IDs after normalization.
