Added training signal health panel to the dashboard — shows Recovery, Sleep, HRV, Load, and Biometrics status at a glance. Expands automatically when signals are active, collapses to a minimal summary when everything looks good.
Training signals now fully wired: fatigue indicators (HRV trend, RHR trend, overreaching risk) are computed and fed into adaptation signals across the dashboard, TrainNow, and Coach+ chat — so workout recommendations reflect your true recovery state rather than surface wellness alone.
Added HRV Stability (CV) to the analytics page — a new chart shows your week-to-week HRV consistency based on the coefficient of variation, with green/amber/red bands so you can see at a glance whether your autonomic nervous system is stable or volatile
HRV-CV now appears in the HRV summary card on the analytics page, giving you a quick stability reading alongside your average HRV
The AI coach now considers your HRV stability when generating workouts — if your week has been physiologically volatile (CV > 25%), it favors moderate intensity even when your daily HRV looks normal
