Pairing 6/6: compare daily and workout capabilities - #696
Section 6 of the split requested in #669. Draft until preceding sections land. This upstream PR temporarily includes those dependencies; review this section through the link below.
Add the device capability table, daily/workout indicators and the paired-device card. Claims come from the existing compute input rules, with conditional or unverified capabilities labelled and absent inputs left absent.
This optional presentation section is last, as Abdul requested. It can be deferred independently of the identity fix and pairing help. No analytics implementation or version changes are included.
This PR adds device capability comparisons and pairing interfaces, routes scanned-device selections through pairing and replacement flows, updates paired-device profile views, and adds state guards for replacement, alarm ownership, and live-step coverage.
Changes: Device pairing and management
Layer / File(s)
Summary
Capability model and comparison views lib/ble/slot_comparison.dart, lib/ui2/pairing/slot_comparison_view.dart, lib/ui2/pairing/pair_text.dart, lib/ui2/pairing/device_slot_card.dart, lib/ui2/pairing/pair_widgets.dart
The capability model classifies device claims by slot and status. Pairing and profile components render capability comparisons, labels, and slot indicators.
New screens and sheets offer device filters, band and workout-sensor pairing choices, and replacement confirmation. Localization files add pairing and capability text.
Scan-result pairing and handoff lib/ui2/pairing/add_device_flow.dart, lib/ui2/pairing/device_picker.dart, lib/ui2/profile/pair_sensor.dart
AddDeviceFlow routes scanned devices through confirmation, pairing, and band handoff. DevicePicker and PairSensor implement the flow and report pairing outcomes.
Replacement and reconnect lifecycle lib/state/app_state.dart, lib/state/sync_controller.dart, lib/ble/accessory_setup.dart, lib/state/alarm_schedule.dart, lib/sync/background_sync.dart, lib/data/backup_extras.dart
AppState coordinates replacement and blocks selected callbacks during the operation. SyncController waits for reconnect attempts before replacement. Alarm epochs are scoped to paired-device IDs, and the old iOS accessory can be removed after replacement.

Band replacement has a narrow edge case: if a candidate band streams live data before the swap is confirmed and the swap then fails, its steps can be recorded against the old band. Two other rare rollback and wait-time edge cases are deferred to a follow-up PR. The capability comparison UI and localization changes show no concrete defect.

Explanation
The title "Pairing 6/6: compare daily and workout capabilities" matches the main change. The PR adds a device capability comparison table (slot_comparison.dart, slot_comparison_view.dart, DeviceSlotCard) that contrasts everyday and workout-only capabilities. The "6/6" step number is a series marker and does not describe the change, but the rest of the title is specific and accurate.

kReasonEarly switch to use a new localized caption that communicates the value
is provisional, separately from the three-night requirement; add the string to
app_en.arb and regenerate the localization outputs.
Review comments at @lib/state/app_state.dart:
- Line 4816: Update the replacement rollback flow around _resetBandIdentity to
preserve the old band's pairedIsMaverick value: capture it before resetting
identity and restore it when replacement fails and the old band cannot
reconnect. Keep the existing successful replacement behavior unchanged.
- Line 4784: Update the replacement-commit flow around _resetBandIdentity so it
clears both the in-memory _savedAlarm and the persisted global alarm_epoch only
after the replacement commits. Preserve the old band's alarm state when a
replacement attempt fails.
Review comments at @lib/ui2/onboarding/pairing.dart:
- Line 204: Update the `resetEntry` value in the pairing flow to pass
`widget.entry` only when `widget.modelKnown` is true; otherwise pass `null` so
failure help remains model-neutral until discovery establishes the model.
Review comments at @lib/ui2/pairing/add_device_flow.dart:
- Line 192: In the add-device flow before calling io.pair, check whether cand’s
remote ID matches the primary band’s remote ID and reject that candidate before
connecting or saving it. Preserve the existing pairing flow for other devices so
pairNotifyDevice cannot create a separate ble_hrs row for the main band.
- Line 228: Update the post-connect retry call to _pair so a main-capable
discovered device uses kBleHrs rather than the scanned entry; keep using found
for devices that are not main-capable.
Review comments at @lib/ui2/pairing/pair_sheets.dart:
- Line 50: Update the pairing sheet logic around slotComparisonFor(band) so an
unknown model does not use generation-specific capabilities from the supplied
band; use shared capabilities or keep those capabilities unconfirmed until
identification completes, while preserving the confirmed-generation comparison
behavior.
Review comments at @lib/ui2/profile/pair_sensor.dart:
- Around line 377-378: In the flow around AddDeviceFlow.afterConnect, determine
whether the main band changed by capturing its remote ID before the call and
comparing it with the current main band's remote ID afterward. Pass true to
afterBandFoundText only when the current ID is non-null and differs from the
previous ID; do not compare against the scanned device's ID.

lib/state/app_state.dart:3601 Major · Data Integrity & Integration · Quick win
Gate live-frame ingestion while a replacement is in progress.
Candidate IMU frames can reach _onLiveFrame before confirm completes. The router has no replacement guard. Its step path can then add candidate samples to _gaitRuns. The replacement clears that state before bootstrap, but rollback does not clear it. A later pedometer finalization can bank the candidate steps under the retained pairing.
This path requires an active IMU-relevant owner, such as a workout, breathing session, or movement sampling window, during the replacement attempt.
Skip the router while a replacement is in progress. The flag is set before the old link disconnects, so old-band frames received in that short window are also skipped.
Suggested fix
void _onLiveFrame(int pt, String hex, int? recTs) {
+ // Candidate frames must not enter the retained pairing's pedometer before confirmation.+ if (_replacingBand) return;

lib/state/app_state.dart:3670 Minor · Data Integrity & Integration · Quick win
Ignore live frames while a band replacement is in progress.
_onLiveFrame does not check _replacingBand, unlike the other candidate-facing callbacks. Once the candidate reaches READY, the 30-second keep-alive reconcile can start its live streams. If a full minute of accel frames is committed before the attempt fails, the checkpoint is written. The rollback openSession() then recovers that checkpoint into live_coverage before it resets the pedometer, so the unconfirmed band's steps can be recorded against the old pairing. Rollback does not clear them.
Return early from _onLiveFrame while a replacement or reset is active, as _onRecord does:
Suggested fix
void _onLiveFrame(int pt, String hex, int? recTs) {
+ if (_resetting || _replacingBand) return; // candidate is not the primary yet
// NOTE: deliberately do NOT advance _lastRecTs from live frames. Live frames
