Panel rebuilt as the heat matrix: verdict header (ring + newest fault named with its age, cable cell top right), one row per check with NOW / last-90s-at-5s-a-cell / since-reset columns, noise as a blue context lane; history.go keeps the 18-slot wall-time ring (per-class fault deltas, SNR minima, rate verdicts, measuring gray) plus since-reset aggregates and fault ages that clear on reset; noise cycle grid-locked to the shared slot clock so cells never straddle a phase and flicker, presence granted at boot until the first up-phase verdict; check/cross stroked as capsule marks (font has neither), line rate is a pure verdict everywhere, footer is a three-line stat stack beside hold-to-reset; old panel/chip/stat-grid machinery deleted; mockups/ gitignored
