Bounded local processing

Counts are not diagnosis
Keyword groups and timestamps are pattern counts only. This tool does not use AI or infer causes, severity, ownership, or fixes.
GOOD TO KNOW
Common questions
What timestamps are detected?
Common ISO-like dates, time-of-day values, and bracketed date-time prefixes are counted when they match the built-in pattern.
Does it explain an incident?
No. It reports deterministic counts and leaves interpretation to you.
