Level 2 · Also detected, ranked lower
- Stream 003 — Activity briefly disappears for one second, then returns to normal.second 1
- Stream 002 — Activity briefly disappears for one second, then returns to normal.second 3
- Stream 001 — A small message-count change, isolated to 1 second.second 2
Level 3 · Bucket-level detail
- Comparable range: 9 complete one-second Buckets (complete_common_one_second_buckets_only rule).
- Top finding canonical Stream identifier: stream.unmapped.004, Buckets 5–8.
- Top finding difference type: Reference active, Target empty.
- Original topic/source names are not included in the canonical bundle by design ("original_topic_name_included": false) -- Stream labels above are the neutral identifier Compare itself receives.
- Candidate-D (alternating empty/non-empty pattern) findings: 0 — a sustained phase-offset-shaped pattern is a structural classification, not a determination of cause.
Level 3 · How the ranking works
Comparison basis: Reference Run and Target Run were both processed by the same Adapter bundle (one bucket contract), so this comparison is exact by construction.
Findings are ordered by Compare's own deterministic ranking rule: a complete Reference/Target activity mismatch always ranks above a partial message-count difference; within the same kind of difference, a Stream that differs more persistently across the comparable Buckets ranks above one that differs only briefly. This is a fixed, reproducible ordering rule — never a severity, fault, or root-cause judgment. There is no AI decision stage in this ranking.
