Ordered by the unit-free shift magnitude (after - before) / (after + before) descending (1.0 = appeared from a zero baseline, 1/3 = doubled), so the most significant shifts lead regardless of the signal's units — nothing is filtered out; judge significance from `before`/`after` (raw signal units: %, µs, logs, profile cost). Optionally filter by `service` and a `from_ts`/`to_ts` window (microseconds since the Unix epoch) over the shift time. Each row carries a ready-to-run `drill_down_sql` for POST /v1/query. Rows whose shifts fall in the same or adjacent 5-minute detection bucket on the same service share an `incident_id` — one incident across signals, not N independent anomalies (the correlation window is the detection pass's own bucket resolution, never a tuned threshold); `incident_id` is null for uncorrelated rows.
