ultrahuman ring air: pair + drain, raw archive only - #359
Conversation
no auth on this wire at all, so pairing is the plain notify-class step. drains by record index (no trim, no ack) and banks every 32-byte record to raw_archive verbatim. zero derivable signals.
Reviewer's GuideAdds Ultrahuman Ring Air as an experimental, pairable secondary band that connects without authentication, drains history by record index, archives each 32-byte record verbatim, and persists progress only after confirmed commits; the change also wires pairing/sync UI and comprehensive replay-based state-machine tests. It depends on the corresponding protocol package PR being merged and pinned. Sequence diagram for Ultrahuman Ring Air history syncsequenceDiagram

📝 WalkthroughWalkthroughAdds Ultrahuman Ring Air support. The change defines BLE characteristics, drains indexed raw recordings, archives records, persists cursors, handles pairing and forgetting, and adds foreground and background synchronization actions. ChangesUltrahuman Ring Air support

Hey - I've reviewed your changes and they look great!
Sourcery assessment
Needs a human reviewer. If the unverified BLE framing, record layout, or cursor behavior is wrong, the sync can persist malformed health records, incorrect timestamps, or skip records after advancing its bookmark. Reverting stops further syncs, but already archived rows and cursor state outlive the revert and would need to be identified and repaired or re-imported.

- Line 36: Update the openstrap_protocol dependency revision in pubspec.yaml and
regenerate pubspec.lock to a revision whose package barrel exports the
Ultrahuman APIs used by Ultrahuman and UltrahumanLink. The affected sites are
lib/ble/adapters/ultrahuman.dart:36-36 and lib/ble/ultrahuman_link.dart:36-36;
no direct source changes are required there.
In `@lib/ble/ultrahuman_link.dart`:
- Line 191: Update _sync() so cleanup runs in a finally block even when
BandHost.stop() throws: ensure cursor draining, state reset, and
BluetoothDevice.disconnect() still execute, while preserving error propagation
and secondary-link release behavior.
- Around line 76-79: Update the device deletion flow around instance.stop() and
the suspended _sync() operation to invalidate active synchronization before
awaiting stop. Add and increment a sync generation or cancellation token, then
check it after each await in _sync() before connecting or creating the host so
invalidated sync cannot resume and archive records for the deleted deviceId.

background_sync.dart called OuraLink.instance.sync() in its finally block but never UltrahumanLink — the ring paired and synced manually but was never drained on its own.

a fail frame after one or more good ok frames in the same 0x04 pull used to discard everything collected so far. now it keeps the good records (same as the empty branch already did) and only ends the drain after banking them, so a ring that fails at a deterministic offset can still make forward progress instead of re-fetching the same frames forever.

adds Ultrahuman Ring Air as a pairable band. no envelope on this wire, drains by record index straight to raw_archive, decodes nothing. depends on protocol PR 51 merging first (pin needs the bump once it lands, used a local override for this branch's own CI).
