Freshness clocks

Event 1 of 12
Four stale-quote diagnostic clocksBars compare source-event age, last quote transport age, unchanged duration, and heartbeat age with their thresholds.

Maximum ages trigger on >. Unchanged duration triggers on ≥. A rejected clock comparison updates no state.

What to notice now

The first accepted quote establishes all anchors. Nothing is stale merely because the pair has not changed yet.
