A chart is reliable only when its tier is not blocked/indistinct and the saved minute (provenance window_offset_minutes) sits in that chart's head segment, or the chart never changes in the window; a missing offset is not reliable. The saved minute does not move with later results, and D7 falls back to the D1 head midpoint when heads do not intersect, so the tier alone could name a sign the saved minute does not have.
