pairs and connects like the heart-rate strap does, no handshake, no key. control-point write starts the ppi stream at workout time; decodes hr + beat interval into the same shape ble_hrs already emits. experimental — nothing derives from it yet.
Reviewer's GuideIntroduces an experimental Polar Verity Sense/OH1 secondary sensor path: a PMD GATT adapter streams and decodes online PPI data after a control-point handshake, while a dedicated link manages workout-scoped pairing, connection lifecycle, and persistence integration; the UI and replay infrastructure are updated accordingly.

Hey - I've reviewed your changes and they look great!
Sourcery assessment
Needs a human reviewer. If the PMD framing or timing interpretation is wrong, the adapter can persist incorrect heart-rate and RR samples from Polar sensors into workout records, and reverting would only stop future writes. The affected sessions would need bounded cleanup or correction, but this does not create an inherently irreversible external action.

CI's committed pin (471034c) predates protocol#45's PMD control-point and PPI decoder, so polar_pmd.dart referenced undefined symbols in flutter analyze. Interim PR-branch pin until protocol#45 merges.

before accepting the session. Reject or terminate the connection when either
security requirement is not met, while preserving normal PMD operation for
compliant links.
In `@lib/ble/adapters/adapter.dart`:
- Line 344: Update the close flow around the _channels drain loop and close() so
shutdown prevents notify() from creating new controllers, or repeatedly drains
controllers added while awaiting close(). Do not clear _channels until all
controllers have been closed, ensuring teardown cannot leave newly created
streams open.
In `@lib/state/app_state.dart`:
- Line 5750: Update AppState’s live workout setup and teardown around
PolarPmdLink.instance.arm() to subscribe and unsubscribe
PolarPmdLink.instance.reading alongside HrsLink.instance.reading. Route PMD
notifications through the same live-reading handler so liveHr, the trace,
workout zones, calories, idle detection, and UI receive PMD samples.

devices.dart tracked whether a paired sensor was live by comparing its adapter_id to kBleHrs directly, so a Polar row never lit up connected even while PolarPmdLink was armed and streaming. liveSources now takes the set of adapter ids that are actually live, and MyDevices nests a second ValueListenableBuilder on PolarPmdLink.reading to build it. forgetDevice's non-Oura branch disarmed HrsLink unconditionally, which is a no-op for a Polar row - the live GATT session and its writes kept going after the row was deleted. It now routes to PolarPmdLink.disarm() for a polar_pmd row. Also fixed the pubspec repin comment, which pointed at the wrong gate: PolarPmdAdapter.signals isn't empty, kDerivableSources is.

Persistent review updated to latest commit 9e1c4e4 |
ReplayBandLink.close() cleared _channels after one snapshot, so a channel a lazy adapter subscribes to mid-teardown was never closed. Now it drains in rounds, clearing before each round so a late entry lands in a fresh map the next round picks up. PolarPmdLink.instance.reading had no AppState listener, so PMD samples armed the link but never reached liveHr, workout zones, or the live trace. Wired the same way HrsLink already is, with its own trace id since both sensors can be armed at once.

User description
pairs a polar verity sense or oh1 as a second sensor alongside your band, same picker as the chest-strap/oura rows. armed by a workout like the hrs strap, streams the PMD service's ppi (beat + interval) online — no history, nothing stored on the sensor. no signal is claimed yet (empty kDerivableSources), same as every other unverified band here.
needs OpenStrap/protocol#45 merged and the pin in pubspec.yaml bumped before this can merge — using a local pubspec_overrides.yaml for now.
