Give up the radio for the link, not for the search
Two failures on the tablet, one of them mine from an hour ago. The real one first. A trainer that drops mid-ride could not get back: its supervisor reconnects on its own (FR-1.10) and those attempts never pass through `DeviceRegistry::connect`, so nothing suspended the device list for them. On Android a GATT link that is discovering services while a scan is running is killed by the platform, and the log has it exactly — a reconnect at 13:07:18 dying with `Disconnected while discovering services`, inside a list-scan session opened at 13:07:02. My first fix was to suspend the list whenever the trainer was mid-connect. That was drawn around the wrong thing. `Connecting` covers the 15 s *search*, `Reconnecting` covers the backoff between attempts, and against an asleep trainer those alternate for the whole of RECONNECT_ATTEMPTS — so the list scan went off the air for minutes and every other device starved with it. A pod that dropped could never be seen again, which is what "the pods disconnect after 40 seconds" was. The window that matters is narrower than either: connect, then discover services. `scan::gatt_setup` marks it — an RAII guard taken by the trainer, pod and heart rate paths the moment their search returns a peripheral — and the device list yields only for that. Measured on the tablet: 1.2 s of yielding for a heart rate connect, then straight back to one session per 21 s. Also: the "+ pod seen; the − pod speaks for the pair" line is logged once per run of refusals rather than once per sighting. The device list republishes several times a second and every pass re-reported a visible pod — 274 identical lines in five minutes, burying the connect failures the log was being read for.

Never ride a link we did not open, and put a shifter on the other pod
Three changes, all from the same evening on the hardware. **Never adopt an existing link.** `setup_session` skipped connecting when it found the peripheral already connected, which is not a shortcut: it means someone else left it that way, and after a shutdown that ran out of budget that someone is our own previous run. The inherited session answers the handshake and streams battery every five seconds while never delivering a button, which reads as broken hardware — it was diagnosed as a dead pod, a wrong bit map, mis-filed pods and a lapsed Zwift unlock before anyone looked at what the last run failed to close. Any pre-existing link is now dropped first, in all three actors, so every connection starts identical. **A watchdog for the same state, should it arise another way.** Deliberately narrow: a link that is plainly alive — frames arriving inside STALE_AFTER — and has never carried a button since it came up is recycled after 150 s. Not "the rider has not shifted lately", which is normal and would strand a pod that only advertises while awake. A link that has delivered even one press is exempt for its lifetime. **`Y` on the `+` pod shifts down.** Shifting down lived entirely on the `−` pod's paddle, so one pod was a single point of failure for half the drivetrain — and with no on-screen gear control on Android, a rider whose left pod goes quiet is stuck in whatever gear they were in, mid-interval, with no way out. This is RISK-9's documented mitigation and it should have been there from the start. Applied in Rust beside the paddles so a shift behaves the same wherever it comes from; removed from the webview so it cannot fire twice. Mode cycling keeps the `m` key. Verified on the tablet: `Y` moved the gear 12 -> 9, and the pods reconnected cleanly with no stale link to purge. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

Close the link before the budget runs out, not after
A pod that was connected, reporting battery every five seconds, and sending no button frames at all cost most of an evening. The cause was not in the decode: it was that the previous run never let go of the link. `Actor::teardown` unsubscribed every notifying characteristic before disconnecting, each under its own two-second timeout. A Click carries five of them, so the exit path could spend ten seconds on optional work against a supervisor budget of three. The supervisor gave up first, the process exited, and `disconnect` was never reached — leaving BlueZ holding the pod with no application running. The next connect inherited that half-dead session, and a half-dead session streams battery and no buttons, which reads exactly like broken hardware. Measured directly: both apps stopped, `bluetoothctl devices Connected` still listing the pod. It also explains the connect failures that came with it — `le-connection-abort-by-local`, then `service discovery timed out` — and why the fault came and went, since it depended on whether the last exit happened to time out. Nothing is lost by dropping the unsubscribes. The link going down clears the peripheral's CCCDs anyway, so they were only ever politeness toward a connection about to be destroyed. The heart rate actor had the same shape with one characteristic instead of five; the trainer's safety writes stay, because SAF-2 is not optional. All three now say what a timed-out disconnect costs. The old message named the symptom and not the consequence, and the consequence lands on the *next* run — which is precisely why this hid for so long. Also logs which pod reported which button. A pod reporting a button that belongs to the other one is invisible downstream, because the input carries the button and never its source. Fixes both platforms at once: this is `crates/ble`, and Android is the worse case — a leaked link there survives the app being swiped away. Verified with four connect/disconnect cycles against the `−` pod: every button registers on its documented bit (D-pad 0-3, paddle 8), and BlueZ holds nothing afterwards. That satisfies TASK-0(d) and retires RISK-9. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

Stream heart rate from a strap or watch into the ride and the FIT file
A new HRM client in the BLE crate follows the crate's split: the 0x2A37 decoder is a pure function over bytes (u8/u16 formats, the three-state sensor-contact field, straps that append energy/RR data), and only the actor touches the radio. Anything exposing the standard Heart Rate Service works — a chest strap, or a Garmin watch with Broadcast Heart Rate on. A single-slot supervisor in the app owns the link, shaped like the trainer's and the controller's. It publishes bpm on a watch channel the session backend stamps onto each tick's telemetry — never over a heart rate FTMS itself reported, on the same authority rule as the Zwift cadence merge — and it clears the reading after eight silent seconds, so a strap taken off records nothing rather than a flatline of the last real value. From there the existing pipeline does the rest: ride screen tile, FIT records, avg/max in lap and session. The device list routes heart-rate rows to the supervisor, keeps the row alive while connected (a connected monitor stops advertising), and shows the live bpm as proof data is flowing — a connected-but-silent monitor otherwise looks exactly like a working one.
