- TieredBuffer: replace MEAN binning with MIN_MAX (min+max per bin). Mathematically composable: MIN(bin_mins)=global_MIN, MAX(bin_maxes)=global_MAX. Eliminates tier-boundary visual artifacts. TIER1/TIER2 capacity doubled (2 samples/bin). - LodMode: remove MEAN. Only MIN_MAX and LTTB remain. MEAN introduced values never present in raw signal — disinformation for sensor data. - ChartConfig: default lodMode changed to MIN_MAX. - Version: 0.4.1-SNAPSHOT → 0.5.0-SNAPSHOT Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
