Watch sessions now run an HKLiveWorkoutBuilder: heart rate and active
energy are collected live (shown in an in-workout HUD), saved to Health
as a real HKWorkout on completion, and carried back to the phone as
WorkoutMetrics on the workout document. Phone-only workouts get an
estimated Health workout (MET x bodyweight x duration) after a 10s
debounce that a late-arriving watch session cancels; a launch sweep
backfills workouts completed within the last day. Dedupe is keyed on
metrics.healthKitWorkoutUUID plus the metrics source.
Splits gain an activity type (strength, functional, HIIT, core, cardio,
cycling) that categorizes the Health workout and picks the MET value.
A post-workout summary sheet (duration, calories, avg/max HR, HR zones,
total volume) fills in live and is also shown on completed workouts.
Weights can now display in lb or kg (display-only relabel), synced to
the watch over the existing application context.
WorkoutDocument schema 1->2 (metrics are irreplaceable, so older apps
must quarantine rather than strip them); cache schema 2 rebuilds the
SwiftData store with the new metric columns. Deleting a workout in the
app intentionally leaves its Health record in place.
Watch-side follow-through for the End Workout flow:
- The phone now pushes an authoritative set (in-progress, not-started, and
completed within 24h) instead of the 25 most-recent workouts, and the watch
prunes any workout absent from it. So a Discard/Delete (or a completed run aging
out) drops off the watch, empties its active list, and ends the HKWorkoutSession
— fixing the persistent wrist-raise re-foregrounding. The watch never originates
a workout, so pruning can't lose local data; the 24h grace keeps a just-finished
run on screen. The gate pops if the run you're viewing is pruned.
UX tweaks:
- The in-workout ⋯ is now a pull-down Menu (Add Exercise / End Workout) rather than
an action sheet.
- Starting a split while another workout is still active now prompts to end the
current one(s) — keeping their progress — or run in parallel. Wired into both
start paths (the split picker and "Start This Split"), via a shared
WorkoutDocument.endKeepingProgress() helper.

Publish an exclusive-edit lock (editingWorkoutID / editingSplitID) in the
phone→watch application context. While the phone has a workout's exercise
(ExerciseView) or a split (SplitDetailView) open in an editor, the watch pops
out of that run, blocks re-entry, and shows it as "Editing on iPhone" — so the
two devices never drive the same run at once and the watch can't clobber the
phone's edit with a stale optimistic write. The lock clears when the editor
closes; absent keys in the latest-wins context mean "not editing".

Watch root lists every in-progress workout; picking an exercise runs a paged Ready -> work/rest -> Finish flow (One More + auto-firing Done), with a phase-dot row and brand-tinted count-up/down timers. Includes the configurable rest and auto-finish settings synced over WatchConnectivity and the wrist-down timer fix.
- Redesign the watch app into an active-workout runner: a root gate shows the
in-progress workout's exercises or prompts to start one on iPhone, and each
exercise runs as a horizontally-paged HIIT cycle (count-up work, count-down
rest with final-three-second haptics + auto-advance, One More / Done on the
last set). Replaces the old history list.
- Add a configurable rest-between-sets duration in iPhone Settings (default 45s),
synced to the watch over WatchConnectivity.
- Launch the watch app into the session when a workout starts on the phone via
HealthKit (startWatchApp); the watch runs an HKWorkoutSession for foreground
runtime and ends it when the workout finishes. Adds the HealthKit entitlement +
Health usage strings on both targets and WKBackgroundModes on the watch.
