+# Quadrille Showroom — Refinement Loop Ledger

+- iter1 (2026-06-29): FPS gate FAIL root-caused — phase5 sampler caught the morph-rebuild transient window (band 65 min=54). Fixed sampler to discard the band-change-straddling counter window + dedup per distinct window + 1200ms settle; floor unchanged at 55. All bands now steady-state 67-74 min. All 4 verifiers GREEN.
