+## KC-39 — Workout state lost on reinstall/update (incomplete iCloud restore)
+
+**Status:** Fixed (build-verified)
+**Reported by:** User
+**Area:** Workout / iCloud sync
+
+### Description
+Workout state was lost after app updates / fresh installs.
+
+### Root cause
+`save()` pushes 7 workout keys to iCloud KVS (programs, schedule, activePid,
+completedDates, history, missedDates, compensations), but `WorkoutViewModel.init`
+only `restoreIfMissing(...)` for the first four. So **history, missed dates, and
+rest-day compensations** were uploaded to iCloud but never restored on a fresh
+launch — silently lost on reinstall/update.
+
+### Fix
+Added the three missing `restoreIfMissing` calls (`history`, `missedDates`,
+`compensations`) so restore is symmetric with save. (Per-day `lastActiveDay` is
+transient set-reset state and intentionally not synced.)
+
+Files: `ExerciseModels.swift`.
+
+### Note
+Cross-device *live* refresh while the app is open isn't wired (`WorkoutViewModel`
+doesn't observe `kisaniCloudDataRefreshed`) — out of scope; the restore-on-launch
+path is what preserves state across updates.
