feat(ble): wire 8 more BLE broadcast fields into BleBroadcastStreamGlue

[Bre77]

Intent

Extend BleBroadcastStreamGlue so every field derivable from a BLE broadcast is glued into teslemetry-stream's ingest() path, per captain's ruling: any field we can derive from a Bluetooth broadcast should be glued into the ingest method for teslemetry stream so local broadcasts and the hundreds-of-fields stream can both be consumed downstream.

Before this change, BleBroadcastStreamGlue wired only 3 of the 14 BLE-derivable fields (lock state, charge port, front trunk). This change wires 8 more (11 total): rear trunk, all 4 side doors (front/rear driver/passenger), gear, tonneau position, and tonneau open percent - all via the DoorState dict leaves and the Gear/TonneauPosition/TonneauOpenPercent Signal names.

I installed the real teslemetry-stream 0.13.0 package into a scratch venv and read its actual TeslemetryStreamVehicle listener source (not the local funnel.py maps) to verify wire shapes rather than guessing:

• Gear and TonneauPosition are NOT booleans - they are -shaped strings (e.g. "ShiftStateP", "TonneauPositionStateClosed") because that package's own listeners strip a TeslemetryEnum prefix before handing callers a bare value. I added GEAR_STATES and TONNEAU_POSITION_STATES maps in stream_glue.py (not funnel.py, which intentionally stays scoped to its existing 3 fields) to produce those exact wire strings.
• TonneauPosition is only 3-valued (Closed/PartiallyOpen/FullyOpen), coarser than VCSEC's 7-value ClosureState_E, so only CLOSED/OPEN/AJAR map unambiguously; OPENING/CLOSING join UNKNOWN/FAILED_UNLATCH as intentionally unmapped.
• The 6 DoorState leaves use the exact key names teslemetry-stream's own listen_FrontDriverDoor/etc. read via dict.get() (DriverFront/DriverRear/PassengerFront/PassengerRear/TrunkFront/TrunkRear).

Three of the 14 fields are deliberately left unwired, each because of a genuine teslemetry-stream API gap rather than something I could work around:

• Vehicle sleep status: teslemetry-stream's ingest() unconditionally nests its payload under the "data" key of a wire event (signal-topic shape). Sleep status streams on a separate "state" topic (online/offline/asleep) that ingest() has no way to produce - there's no ingest_state() or topic parameter.
• User presence and UI desire: teslemetry-stream 0.13.0 has no Signal enum entry or listen_* method for either today, so there's no verified wire field name to target.

These three should be called out in the PR body as named follow-ups (the specific teslemetry-stream addition each needs), not hacked around with a guessed field name.

I discovered along the way that VCSEC's gear field is a scalar enum with no proto3 presence (like vehicleLockState), so it fires - with GEAR_UNKNOWN as a legitimate reading - on every VCSEC status broadcast, not just gear changes. This matches the existing established pattern for vehicleLockState/vehicleSleepStatus/userPresence in broadcast.py, so I updated the pre-existing (and already slightly stale) AGENTS.md line describing that scalar-field set to also list gear and uiDesire. I updated existing tests in tests/test_ble_stream_glue.py to filter per-field (matching the pattern the charge-port test already used) since Locked and Gear now both fire on most single-field test broadcasts, rather than asserting an exact single-call list. I added new tests for every newly-wired mapping, each citing the exact teslemetry-stream field/Signal name it targets, plus tests for the two unmapped-state cases (ambiguous closures, unmapped tonneau positions).

Full test suite (759 tests), ruff check, ruff format, and pyright strict all pass. Only files touched: tesla_fleet_api/tesla/vehicle/stream_glue.py, tests/test_ble_stream_glue.py, docs/bluetooth_vehicles.md, AGENTS.md.

What Changed

• BleBroadcastStreamGlue (tesla_fleet_api/tesla/vehicle/stream_glue.py) now wires 11 of the 14 BLE-derivable broadcast fields into sink.ingest() (up from 3): rear trunk and all 4 side doors via a new shared _ingest_door_state() helper over the DoorState dict leaves, plus gear and tonneau position/open-percent via new GEAR_STATES and TONNEAU_POSITION_STATES wire-string maps (<Prefix><Option>-shaped strings matching teslemetry-stream's own listener output, e.g. "ShiftStateP", "TonneauPositionStateClosed"); TONNEAU_POSITION_STATES only maps CLOSED/OPEN/AJAR, leaving OPENING/CLOSING/UNKNOWN/FAILED_UNLATCH unmapped.
• tests/test_ble_stream_glue.py gains coverage for every newly-wired mapping and the two unmapped-state cases, and switches existing assertions to per-field filtering (matching the prior charge-port test pattern) since Locked and Gear now both fire on most single-field test broadcasts.
• AGENTS.md and docs/bluetooth_vehicles.md are updated to describe the glue's new 11-field coverage, list gear/uiDesire alongside the other no-proto3-presence scalar broadcast fields, and document vehicle sleep status, user presence, and UI desire as fields deliberately left unwired pending specific teslemetry-stream API gaps (no state-topic-shaped ingest() path for sleep status; no Signal/listen_* entry at all for user presence or UI desire in teslemetry-stream 0.13.0).

Risk Assessment

✅ Low: The change is a well-bounded, additive extension of an existing glue module; every new field mapping (Gear/TonneauPosition wire strings, DoorState leaf keys) was independently verified against the real installed teslemetry-stream 0.13.0 package source and matches exactly, tests exercise real observable ingest() behavior rather than source-string matching, and the diff introduces no changes to command paths, proto handling, or other higher-risk BLE machinery.

Testing

Ran the targeted test_ble_stream_glue.py/test_proto_coverage_lock.py suite (22 tests, all passing) and, since unit tests alone only prove internal consistency against a mocked sink, went further and drove the change end-to-end against the real, unmodified teslemetry-stream 0.13.0 package installed in a scratch venv — confirming its actual listen_Gear/listen_TonneauPosition/listen_TonneauOpenPercent/listen_FrontDriverDoor/listen_FrontPassengerDoor/listen_RearDriverDoor/listen_RearPassengerDoor callbacks correctly decode a real BLE broadcast routed through BleBroadcastStreamGlue. This also verified the PR's central factual claim (the ShiftState/TonneauPositionState wire-string shapes) directly against the dependency's own source rather than trusting the description. An initial-looking anomaly (per-door DoorState events arriving fragmented, one key at a time) was traced to the real package's own documented no-merge ingest() semantics and bool | None-typed listeners, not a defect in this change. No actionable findings; all scratch/verification artifacts were removed from outside the evidence directory.
