# Week 17

The 0‑slot artifact is gone. 
* rate(fcr_confirmations_by_slots_total{slots="0"}[5m]) ≈ 0
* clamp_min(rate(fcr_confirmations_total[5m]) − rate(fcr_confirmation_time_seconds_count[5m]), 0) ≈ 0 → no residual 0‑slot artifacts.
* 30m distribution: slots="1" dominates; "2" small; "ge3" ~0
* Median slot delay ≈1; p95 ≲2
