Some bands stopped syncing for good, and pairing the band and extra sensors misbehaved in a lot of places.
first of a stack of six; the others build on this one in order. the matching protocol and analytics fixes reach the app in a follow-up update once they merge.
Fixes pairing and sensor management: Mi Band re-pairs reuse the existing row/key, Oura failed-pair key handling is corrected for different-ring case, forgetting one sensor no longer drops another's live session, and "delete everything" now stops all secondary sensors and drops their pairing keys
Fixes false "synced" status for Garmin, Colmi, Mi Band, Pebble, and Ultrahuman by emitting failure notes when sessions end without real data; sync return values now reflect actual outcome
Android: fixes crash loop when Bluetooth permission is revoked, stops waking after unpair, and exposes battery-optimization exemption and OEM autostart from Settings; several clock-timing bugs fixed (stopwatch vs wall clock for suspect-clock grace, backfill stamp, RTC re-verify interval)

Fix stuck drain, clock timing, and no-progress escalation
Added Android settings shortcuts for battery optimization and manufacturer-specific auto-start.
Added an option to return to the welcome screen when no band is paired.
Added confirmation before forgetting a paired sensor, clearer battery and last-sync details, and a warning if pairing keys remain after a reset.
Expanded device search to include additional WHOOP models.
Bug Fixes
Pairing now respects sensor limits while allowing repairs of existing sensors, with clearer Bluetooth pairing and Mi Band key-error guidance.
Sync now better identifies unanswered or refused device connections, reports incomplete downloads, and avoids connecting to devices forgotten while waiting.
Reconnection retries resume automatically after about 30 minutes, with guidance if pauses recur.
Improved protection against sync or workout activity interfering with resets.
a band that sat flat for years, or whose rtc reset and logged before the
next set_clock, holds records under the plausibility floor at the head of
its flash. every burst of them was a drop-only burst, so the trim was
refused, the band re-offered the same chunk forever and nothing newer was
ever offloaded. set_clock can't re-stamp flash, so no remedy cleared it.
when every drop in a burst is below the absolute floor and all of them are
buffered as raw_archive rows, I now commit those archives and echo the
token. the bytes stay in raw_archive and are never derived. future-dated
and session-window drops still refuse the trim, since a wandering clock
can recover. (#601)
once the SET_CLOCK + bounce remedy had failed enough times to surface
syncClockLost, it still fired on every third refused HISTORY_END with no
limit. a band wedged in that loop and left in range on android got its rtc
rewritten and its link torn down and re-handshaked hundreds of times a night,
draining both batteries for no progress. after give-up the refusal threshold
now doubles per failed remedy (capped), so it still retries occasionally but
stops churning the link. the trim is still always refused.
a commit that banked no records (a bare history-end token, or only
gate-dropped archives) on an install with no cursor yet wrote
rec_ts_hw='0' and counter_hw='0'. 0 is not null, so after a restart home
read 'synced through thu 1 jan 1970' instead of 'no band data yet', and
the session rescore skip lost its decoded-row fallback.
commitSyncBatch now only writes those cursors when a real record moved
them, and the frontier readers go through getRecordFrontier(), which
treats a non-positive value as unset so installs already holding '0'
recover.
…ic clock
the backfill floor was stamped and compared in wall time, so a phone clock
stepping backward on a live link (ntp correcting a fast phone) refused every
periodic and foreground offload until wall time caught up again, which could
be hours of a healthy android link not syncing. the 6 h rtc re-verify had the
same problem, and the stuck-strap detector read a forward step as ten frozen
minutes and flagged the band as no longer handing over its data.
all three now measure elapsed time on the engine's stopwatch. the floor uses
null for 'never this connection' since the stopwatch starts near zero, and
BackfillPolicy treats a negative elapsed as the floor being spent.
moving them onto the engine stopwatch traded one stall for another: the
stopwatch stops while the phone is suspended, so after a night locked the
morning catch-up and the sync button only saw the few awake seconds since
the last offload and were refused by the 90 s floor, and the 6 h rtc
re-verify could slip by days on a phone that mostly sleeps.
both are stamped and compared in wall time again. the backward-step stall
stays fixed in the policies: BackfillPolicy already treats a negative
elapsed as the floor being spent, and the re-verify now goes through
rtcReverifyDue, which does the same. the stuck-strap detector stays on the
stopwatch, where under-counting only delays the trip.
the bond-refusal pause lifts on its own after a 30 minute cooldown, but the
band card said nothing would reconnect until the user acted and told them to
forget and re-pair the band. that pushed a transient refusal streak into a
needless re-pair. the card now says the app tries again by itself in about
30 minutes, and only suggests re-pairing if the pause trips again.
…wered
a mi band re-bound in zepp rejects this phone's key with status 0x04, and
every manual sync connected, failed auth, disconnected and still said
'synced.'. the ultrahuman, colmi, garmin and pebble links had the same
shape: the adapter's stream ended quietly on failure and the link returned
true for any session that got as far as connecting.
the adapters now say why a session ended short: mi band notes the refused
auth status, ultrahuman a refused history request or an unconfirmed batch,
colmi a ring that answered neither its clock nor battery request, garmin a
watch that never opened its data channel, and pebble notes when the watch
sent anything at all (its session never ends on its own). the links return
false on those, and a rejected mi band key gets its own message telling the
user to re-pair.
…yed silent
the earlier change only caught a history request whose write failed. a ring
that received GetRecordings and answered with a failure result before any
record landed still ended the drain quietly, and so did a ring that answered
neither index request nor the first pull. both now end on a failure note
(result_failed:0x.. and no_reply); an empty ok answer is still a ring with
nothing new, and a failure after records were banked still counts as a sync.
a failed vendor write holds every later note back, the failure notes with
them, so the link also reads the host's vendor-write flag after stop.
also moved pebble's lastSyncHeard field above the _makeHost doc comment it
had split off from its function.
… keys
the reset only unpaired the primary band. an armed chest strap or an oura
offload kept committing rows, cursors and anchors into the wiped store, and
the headless piggyback still ran every secondary sync during a reset. the
oura and mi band pairing keys also stayed in the keychain, with no device row
left for a forget to find them.
the reset now discards a live workout, stops every secondary link and drops
both pairing keys for each paired sensor it read before the wipe. bandhost
refuses every database write while the reset gate is up, as do the oura and
ultrahuman cursor writes, and the headless piggyback is skipped during a
reset.
… into the picker
the picker stays open after a pair, and onboarding and re-pair open it
without going through add sensor, so one visit could pair any number of
sensors. the cap check is now shared and runs before each nearby pair and
each sensor category tap. pairing a sensor that already has its row again
is a re-pair, not an addition, and is let through.
…e pairing screen
the picker's check still only guarded the door to the sensor's own pairing
screen, and that screen stays open after a pair and offers "pair another",
so one visit could still pair past the cap. the exact check now runs in the
pair step itself, and a softer one before a scan or the ios accessory
picker starts so nobody scans for a sensor they cannot keep.
a sensor kind that already has a row can still open its own screen to
forget or re-pair it. the ring rewrites its single row on every pair, so
re-pairing it at the cap is allowed; a mi band mints a fresh id each time,
so the nearby path no longer treats its pair as a re-pair of a strap-style
id. the test now drives the real pair step against a database and fails if
the check is removed.
forgetDevice disarmed the hrs/polar link whenever the forgotten row had the
matching adapter, without checking the armed session belonged to that row.
with an old and a new strap both paired, forgetting the old one mid-workout
killed the new one's live hr for the rest of the workout. it now only
disarms when the armed device id is the one being forgotten.
the previous change gated forget's disarm on the armed session's device id,
but that id only exists once the session is published. an arm still waiting
for a link slot or connecting had already read the row, so forgetting that
strap skipped the disarm, deleted the row, and the arm then finished writing
under an id with no row behind it. both links now remember which row an
in-flight arm is for, and forget disarms when either the published or the
arming id matches.
every pairing minted a fresh random device id, so a re-pair (say after a
factory reset) added a second mi band row. syncs went to the new id while
the active wearable kept naming the old one, the stale row's sync button
synced the other band, and the stale row used up one of the two sensor
slots. a re-pair now reuses the paired row's id like the oura ring does,
puts the previous key back if the attempt fails before the band takes the
new one, resets the resume cursor when the remote id changed, and forgets
any duplicate rows an older pairing left.
the previous change reused the paired row's id for any mi band being
paired. pairing writes the new key under that id before the band proves
it, so a second band that took the key and then failed the challenge left
the working band's row pointing at a key it never had, and every later
sync was refused until a factory reset. the id is now reused only for the
row already paired to the same remote id; a different band gets a fresh
id, its failed attempt drops only its own key, and only a successful
pairing replaces the old row. the failure-path key decision is a small
pure function so it can be pinned directly, and forgetting a band now
drops its resume cursor too.
a paired sensor's page was pushed holding the device row as it was when
tapped and never reread it, so after a manual sync said "Synced." the page
still showed the old battery and "3 days ago" until it was reopened. the
page now takes battery_pct and last_seen from the current sensor rows on
each rebuild, selecting only AppState.sensors so it does not rebuild on
every other app tick.
the sensor-row helpers had landed between liveSources' doc comment and the
function, so its opening paragraph documented the battery cast instead. the
helpers now sit above it and the battery one has its own line.
the steps rewrite stopped adding a live session counter to the today tile,
so LiveStepDayWindow lost its only caller but stayed behind with its test.
its doc still described it as the fix for steps not resetting at midnight,
which points anyone chasing that bug at code nothing runs. today's steps
come from per-day spans now and need no rebase. the class had also been
inserted in the middle of DeriveDebouncer's doc comment, so I put that
back together.
FD4B sits in NSAccessorySetupBluetoothServices only so the gen5 fallback
item is declared, but the plist loop turned it into its own picker item
labelled "Band", ahead of the "WHOOP 5.0 / MG" item with the identical
descriptor. I skip the member UUID in that loop so the picker holds one
FD4B item, the labelled one.
(cherry picked from commit 151e4d0231902959c1b0f0306dd026663266a411)
once a band had been paired, the 15-minute keep-alive job stayed scheduled
for the life of the install, even after unpairing or deleting everything,
because nothing ever cancelled it and the worker deliberately doesn't cancel
itself on a prefs read. unpairing now cancels the job by name from the
edge_tracking stop call, and pairing again re-arms it as before. also fixed
the comment that claimed the worker cancelled its own chain.
(cherry picked from commit 134cc2e97447144200b7e8c3f312135a82605527)
…he band's windows
deleteDevice only removed the device row. a user-set rank for the forgotten
id survived, and with no device row the band-day filter could no longer drop
it, so on re-derive the forgotten strap owned every window its old coverage
spanned: the band's hr/rr there was masked out and nothing loaded in its
place. forgetting a non-primary device now deletes its signal_priority rows
in the same transaction.
(cherry picked from commit 2ab9443b145548333040fe7a40639d7c78db5446)
tapping the whoop row (or a sensor row) pushed the next screen over the
picker without ending the picker's 15 s scan, so the band scan queued on the
scan lock for whatever was left of it while the screen already said it was
looking. the picker now stops its own scan before either push.
(cherry picked from commit 49157b5624b364a32a51722dcce8f5289e216d41)
… line that did nothing when tapped
nothing in the app opens the bluetooth pane, and ios has no public way to.
the card now ends on advice instead: come back after forgetting the band and
tap try again.
(cherry picked from commit c5d05a16fc6da1ab685aec64cbb6f0e38638223f)
unpairing leaves the companion device association in place, so every time the
old band reappeared the os woke the companion service and it started the
tracking foreground service again, notification and headless engine included,
for a user with nothing paired. the appear callback now checks for a paired
band first, the same way the boot receiver and keep-alive worker already do.
(cherry picked from commit 653eff35f75f001adb1e7d0c38d761592a4efe96)
the 'forget this sensor' row there called forgetDevice straight away, with
no confirmation and even while a pair was in flight. for an oura ring or a
mi band that deletes the pairing key the app minted, which the device still
holds, so a stray tap meant a factory reset. it now asks the same question
the device page asks, and is locked while a pair is running.

…vice start
on android 12+ with no companion association and no battery exemption, a
BUZZ_STRAP broadcast arriving while the process was dead called
startForegroundService from the receiver with nothing catching the
ForegroundServiceStartNotAllowedException, so the app crashed and the pending
buzz could be lost because it was written with apply(). the receiver now
commits the pending flag synchronously and starts the service through a
guarded helper that logs the refusal instead of throwing. the boot receiver
uses the same helper, since QUICKBOOT_POWERON is not exempt the way
BOOT_COMPLETED is.

…was revoked
on android 14+ startForeground with the connectedDevice type throws when
nearby devices is revoked. onStartCommand swallowed that and stayed sticky,
so the system killed the process at the foreground-service deadline and the
watchdog, cdm and boot paths kept repeating it. start() now refuses before
calling startForegroundService when neither bluetooth permission is granted,
and a service that never reached the foreground stops itself non-sticky
instead of waiting to be killed.
(cherry picked from commit a718f6840e644dfe591b8c9f42f698e1a5bd953b)
colmi, ultrahuman, garmin and pebble mint their device id from the remote
id, so pairing a replacement device adds a second row next to the old one.
syncs then went to the new row, but the active wearable only moves once its
row is deleted, so derivation kept reading the old device and every new day
came up empty until the developer toggle was flipped by hand. pairing now
moves the active wearable to the new row when the old one is the same kind
of device. only the cursor moves: the old device's days keep what they were
derived from.
(cherry picked from commit ca5cabb80cd9946a3b47f5b388ac3e4c2a0de589)
…g's key
pairing reuses the paired ring's row id even when the ring in hand has a
different remote id, and writes the new key under that id before the ring
proves it. if that other ring acknowledged the key and then stopped
answering mid-challenge, the failure path kept the new key, so the row
still named the old ring while the keychain held a key that ring never
had. every later sync was refused and the only way back was a factory
reset. the new key is now kept only when the ring that took it is the one
the row names; for a different ring the old key goes back. the decision is
a small pure function so it can be pinned directly.
(cherry picked from commit a91a3b1ea8acac645f05a3dc92f6e82bfe0b0657)
…ls it
the colmi, pebble, garmin, coros, ultrahuman and mi band links read the
device row, then wait for a secondary link slot with no timeout. a forget
in that window stopped the link and deleted the row, but the queued sync
still held the ids it had read, so once a slot freed it connected to the
forgotten device and banked its history under a row that no longer
existed. the sync now checks, once it has the slot, that it was not
stopped while waiting, and gives up without touching the radio if it was.

_refuseDuringReset() runs before the asynchronous database call and does not serialize the transaction. If a reset starts after that check, putVendorSleepEpochs or putObservations can write after wipeAll and restore deleted health data. Pass _resetGeneration to both methods, execute each transaction through _withCommitGate, and check ResetGate.changedSince inside the gate.

… like success
- a garmin watch that closed its channel while the last file's final chunk
was still being handled counted as fully synced, though that file's data
was never kept. the session only counts as finished if the stream was
still open when the last file was done.
- forgetting a colmi ring, coros or garmin watch, pebble or ultrahuman ring
while its sync was still looking up the device row did not stop that sync,
which then connected to the deleted device. each forget now bumps a count
the sync checks before it connects, as the mi band and oura ring already do.
- a profile change that overlapped a delete-everything was applied in memory
but not saved, and the editor closed as if it had been. it is now refused
before anything changes and the save fails visibly.
- a sensor's vendor values and sleep stages are now written on the same
queue as the wipe and refused there once a reset has begun, like its
synced records already were.
on the outside-diff host.dart finding (vendor writes vs the reset gate): fixed in bbc095b. putVendorSleepEpochs and putObservations take the session's reset generation now, run on the commit gate, and check it inside the gate like commitSyncBatch, so nothing checked before a reset lands after the wipe.

Do not wipe while a derivation pass can still write.
When DerivationEngine.acquireForReset() times out, it returns false without cancelling or invalidating the pass. resetAllData() then calls LocalDb.wipeAll(). The pass can later write day_result and baselines because its writes do not check ResetGate.generation.
Abort the reset on timeout, or invalidate the pass and await its completion before wiping.

if a derive pass did not finish within two minutes, the reset logged it and
deleted everything anyway, and the pass then wrote its day results and
baselines back into the emptied store. the derive lock is taken first now,
before anything is changed, and a pass that won't finish stops the reset with
nothing deleted.
on the outside-diff app_state.dart finding (wipe while a derive pass can still write): fixed in bee2789. the derive lock is taken right after the sensor lookup now, before anything is changed, and a pass that won't finish in time stops the reset with nothing deleted instead of wiping underneath it.

a reset that gave up before deleting anything had already moved the reset
generation, so every open sync session had its saves refused afterwards for
nothing. the sensor lookup and the derive hold now run before the gate is
raised, so an abort changes nothing.
a noop import left running after its screen closed waited for the derive
lock behind a reset and then wrote its buffered days into the emptied store.
it now stops at its next write once a reset has run.
the seeded wake was 13 h before now, which on an afternoon run in utc lands
before 03:00, where a wake is never pinned, so the test failed on the clock.

User description
Some bands stopped syncing for good, and pairing the band and extra sensors misbehaved in a lot of places.
first of a stack of six; the others build on this one in order. the matching protocol and analytics fixes reach the app in a follow-up update once they merge.

Description
Fixes stuck syncs: bands with pre-2023 records (flat RTC or reset) now archive and trim those records instead of re-delivering forever (Sync deadlocks on a band whose oldest stored records predate kMinPlausibleUnix (revived WHOOP 4.0) #601); no-durable-progress remedy backs off exponentially after give-up instead of churning the link all night
Fixes pairing and sensor management: Mi Band re-pairs reuse the existing row/key, Oura failed-pair key handling is corrected for different-ring case, forgetting one sensor no longer drops another's live session, and "delete everything" now stops all secondary sensors and drops their pairing keys
Fixes false "synced" status for Garmin, Colmi, Mi Band, Pebble, and Ultrahuman by emitting failure notes when sessions end without real data; sync return values now reflect actual outcome
Android: fixes crash loop when Bluetooth permission is revoked, stops waking after unpair, and exposes battery-optimization exemption and OEM autostart from Settings; several clock-timing bugs fixed (stopwatch vs wall clock for suspect-clock grace, backfill stamp, RTC re-verify interval)
