Live frames ride sendMessage, which is reachable-only — and phone→watch
reachability drops exactly when the user is swiping on the phone (wrist
down). A frame that failed to send was staged but never retried until a
reachability edge, and a frame lost outright desynced the run until the
next human transition — sometimes forever, since a reconnect could even
re-send the stale staged frame and yank the peer backwards.
Four fixes, symmetric on both bridges and both run screens:
- A send that fails while nominally reachable now retries with a short
backoff (a few times per staged message) instead of being swallowed.
- Receiving a frame that outranks the staged outbound one drops the
staged frame, so a reconnect re-send can't move the run backwards;
a delivery the staged frame outranks is ignored as stale.
- Every staleness comparison now tie-breaks the shared version sequence
on the frame's wall-clock anchor (LiveProgress.isNewer) — after a
lost frame both devices can mint the same version, and the later
human action must win.
- Durable repair: when the absorbed workout doc shows sets completed
beyond anything the open run screen recorded or followed, it jumps
forward to the first unfinished set's work page — a lost frame now
degrades to a briefly-stale page instead of a stuck one.
Bodyweight motions (no equipment layer, no hide list) now turn the
camera a full revolution every 24 seconds while the motion loops, so
the exercise reads from every side; machine exercises keep their
authored view, since scene equipment is a view-locked billboard and a
hide list describes a single viewpoint.

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.

Stage the latest live-run frame (and the terminal .ended marker) in a
depth-1 latest-wins slot on both bridges, and flush it on reachability/
activation restore. A brief connectivity drop no longer desyncs the
iPhone/Watch run mirror; frames carry a wall-clock anchor so a late
re-send self-corrects rather than reading as stale.

Two-way driving only worked watch->phone: the watch's navigated driver
broadcast and the phone auto-presented a follower cover. The reverse
failed on both ends — the phone's in-list ExerciseProgressView never
broadcast (only its cover did), and the watch had no surface to present
an incoming run.
- Wire the live channel into the phone's in-list driver (broadcast +
follow) via a progressView(logID:) helper in WorkoutLogListView.
- Add a watch follower cover (LiveRunCoverView, mirroring the phone's),
presented from ContentView when the phone drives a run the watch isn't
already in; the watch bridge gains presentable / muteLive.
- Add a navigatedRunID guard on both sides so a device already in the run
follows it inline rather than stacking a cover over itself.
Now starting or driving on either device surfaces the run on the other —
as a follower cover when idle, or inline when already in that run — and
either side can take over.

The propped-up iPhone now runs the real ExerciseProgressView for a live
watch workout instead of a read-only mirror, and the live-run channel is
symmetric — either device can drive the flow and the other follows.
Each page transition is classified human / auto / remote: only human
transitions (swipe, Start, One More, swipe-back reset) are broadcast and
recorded by the actor; auto-advances (rest / timed-work countdown) record
locally but aren't sent, since both devices reach them independently off
the shared wall-clock anchors; an applied remote frame jumps the page
without re-recording or re-broadcasting. That rule is also what stops an
echo loop.
- PhoneConnectivityBridge gains sendLiveProgress/sendLiveEnded (the
missing phone->watch direction); WatchConnectivityBridge receives
frames into an observable liveIncoming via a new didReceiveMessage
route. Both share one increasing per-run version sequence so the
stale-frame guard works across the two devices' counters.
- Both ExerciseProgressViews gain an incomingFrame input + applyIncoming
(syncing setCount for a remote One More); the iPhone one gains the
liveSnapshot/broadcast machinery the watch already had.
- New LiveRunCoverView wraps the real driver for the cover (resolves the
workout, persists via SyncEngine, wires the live channel + close);
ContentView presents it; LiveProgressMirrorView is removed.

Add an ephemeral live-run presence channel (separate from the durable
iCloud progress sync) so a propped-up iPhone can mirror the Watch's
Ready → work/rest → Finish flow in real time as the user swipes.
Watch drives, phone mirrors (read-only), so there's no echo loop:
- Watch's ExerciseProgressView broadcasts a LiveProgress frame on every
phase transition (and an ended signal on leave) via sendMessage,
reachable-only — throwaway presence, never written to iCloud.
- Timers ride as wall-clock anchors (Date kept native in the WC dict to
preserve sub-second precision), so both devices count independently
off shared start times and stay in lockstep without streaming ticks.
- Phone holds a transient LiveRunState; ContentView auto-presents a
read-only LiveProgressMirrorView full-screen cover while a run is live.

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.

Replace Core Data + NSPersistentCloudKitContainer + App-Group store +
WatchConnectivity dictionary sync with the QuickRabbit iCloud-documents
architecture:
- iCloud Drive JSON documents are the sole source of truth (one file per
aggregate: Splits/<ULID>.json, Workouts/YYYY/MM/<ULID>.json), with a
rebuildable SwiftData cache populated only by an NSMetadataQuery observer
and a connect-time reconcile. Soft-delete tombstones; hard iCloud gate.
- Shared model layer (ULID, Codable *Documents + stateless mappers, @Model
cache entities, SwiftData container) compiled into both targets.
- New iPhone<->Watch bridge over WatchConnectivity keyed by ULIDs; the phone
is the sole writer of iCloud Drive, the watch round-trips documents.
- AppServices DI + iCloud-required root gate; Swift 6 strict concurrency.
- Starter splits generated on demand from the bundled YAML catalogs.
- Migrate to XcodeGen (project.yml), iOS 26 / watchOS 26; CloudDocuments
entitlement (drop CloudKit/App Group/aps-environment).
- Duration stored as Int seconds (was a Date epoch hack); fix workout
end-on-create, undismissable delete dialog, toolbar-hiding nav stacks,
and the Settings placeholder.
- Add README/CHANGELOG/LICENSE, .gitignore, refreshed REQUIREMENTS, and the
Scripts/ TestFlight pipeline (release.sh + ASC API scripts).
