The patterns engine learns to wait
Patterns now require three repetitions before they surface in the readout, and a confidence floor before they earn an intervention. Less noise, fewer false alarms.
Added
- Pattern confidence floor — patterns under 0.55 stay hidden until they earn the threshold
- Drift map in Patterns: time-of-day on x, context spread on y
- Per-pattern intervention pairs tagged by effort and payoff
Changed
- Weekly readout publishes Sundays at 07:00 local instead of 06:00 UTC
- Tide chart band now shows the rolling p25–p75 instead of mean ± σ
Fixed
- Cross-workspace cost double-counted when a session crossed midnight (
#412) - Extension pop-up briefly showed the wrong workspace after fast tab switches
