 5. Deletion/export controls, pagination at larger activity counts and moderation.

 Current local development choices are not a claim of production readiness.

+## Rich activity analysis — 1 October 2026
+
+Activity pages now include speed/heart-rate/gradient route colouring with a relative
+10th–90th percentile legend, travel arrows, start/finish markers, and chart-hover
+route location. Six charts cover pace/GAP, HR, elevation/grade, cadence/step length,
+power, and vertical oscillation/ground contact. Recorded energy, aerobic training
+effect and ascent/descent accompany terrain summaries and lap GAP.
+
+GAP uses the Minetti (2002) running energy-cost polynomial
+(https://doi.org/10.1152/japplphysiol.01177.2001), five-sample median elevation,
+and approximately 60 m grade windows. It integrates time over equivalent flat
+distance; missing data, gaps over 10 seconds and slopes outside ±30% are excluded.
+It is explicitly a model estimate, not Garmin/Strava GAP. No invented HR correction:
+terrain summaries show measured, time-weighted HR and explain its response lag.
+
+Migration bdbac89195a7 adds recorded session metrics. All 18 local cached activities
+were refreshed without changing their titles or sharing choices. Future FIT imports
+retain timestamps, cadence, power and running dynamics. Refreshing existing cached
+imports is available through import_cache(..., refresh=True).
