Surfaces the long-horizon training-load model (TrainingLoadEngine) as a card on the Trends screen, all three platforms. Overlays chronic load (CTL, 42-day fitness) and acute load (ATL, 7-day fatigue) on one shared y-scale so the gap between the lines reads as the TSB / form (CTL - ATL); form is the headline number + a footer stat, with CTL/ATL/Days/Form stats below. - Descriptive only: CTL/ATL/TSB never feed the Charge/Readiness score. Load is daily Effort/strain (DailyMetric.strain), not TRIMP. - Models the FULL history, not the range window (chronic load is a 42-day horizon). Honest empty state names how many consecutive Effort days are still needed; a "building" subtitle shows N of 42 while the baseline calibrates. - Calls TrainingLoadEngine.evaluate directly, not the paired evaluateWithTrainingLoad, so it never runs the unused Readiness synthesis. - Apple: isolated card file to keep its type-check cost out of TrendsView. Android: shared-scale two-line Canvas. - Localized de/es/fr/pt-PT on both platforms (xcstrings + strings.xml); CTL/ATL/TSB added to the i18n audit UNIVERSAL acronym set (like HRV).

Build numbers only. MARKETING_VERSION / versionName stay 10.1.1 — the staging line is one above the latest release (v10.1.0) and holds there until 10.1.1 actually ships. versionCode 341 -> 342 and CURRENT_PROJECT_VERSION 223 -> 224, both +1 past the previous staging build so a sideloaded update installs in place rather than being refused as a downgrade. Picks up since the last testing build (f2271cd): backup build provenance (#1422), the CTL/ATL/TSB training-load engine (#1423) and its Trends card (#1425), sleep-vs-wake HR contrast (#1424), the v20 optical decoder + CRC gate (#895), the Sleep UI split (#1426), the WHOOP4 clock-correlation fix (#1427), the settings waist-row layout + copy fix (#1428), hourly Apple step import (#1429), Low refresh (#1430), and Power saving moving into More with a 35% ceiling (#1431).

What
The first UI surface for the training-load model (
TrainingLoadEngine, #1423) — a card on the Trends screen, all three platforms. Overlays CTL (chronic, 42-day fitness) and ATL (acute, 7-day fatigue) on one shared y-scale, so the vertical gap between the lines reads as the TSB / form (CTL − ATL). Form is the headline number; a footer shows CTL / ATL / Form / Days.DailyMetric.strain), not TRIMP.TrainingLoadEngine.evaluatedirectly (not the pairedevaluateWithTrainingLoad), so it never runs the unused Readiness synthesis.Strand/Screens/TrainingLoadCard.swift) to keep its type-check cost out ofTrendsView; reusesChartCard/ChartFooter. Android: shared-scale two-lineCanvasinTrainingLoadCard.kt. Design tokens only.Localization
New copy localized de/es/fr/pt-PT on both platforms (
Localizable.xcstrings+strings.xml× locales). CTL/ATL/TSB added to the i18n audit's UNIVERSAL acronym set (identical in every language, like HRV/SpO2).Tools/i18n_audit.py→ 0 translation gaps, no new hardcoded literals.Validation
