Loop_Light_Handle was hardcoding red for every measure; map L1-L7 to the same R/G/B/yellow/purple/cyan/white table as App guide LEDs.

Problem2: in song mode UI shows 6m(Am) but MIDI played AM7
(E2 A2 E3 G#3 C#4 E4). Root cause: BL_Set_led wrote the LED frame's
chord code into chord_type_index_map of the group middle key
(LED_L6 -> key17), so a guidance frame carrying 0x02 (M7) turned the
Am key into AM7. Remapping on the chord page only helped until the
next LED frame.
- BL_Set_led: light LED only, drop all chord_type_index_map writes;
chord quality is owned by map page 02 03/02 04 (BT_Chord_offset_map)
- handleReadRhythmMap / Return_Light_buff: fix type->protocol read-back
encoding (m7->0x0A, M7->0x02, ad9->0x04, m7-5->0x0B, sus2->0x1F,
sus4->0x1E), re-landing the 0917 verified fix
- BT_Chord_offset_map: accept dominant-7 doc code 0x0D (legacy 0x13 kept)
- tests: test_chord_map_fix.py (16/16 PASS on device),
test_fret_positions.py, test_problem2_song_am.py (7/7 PASS:
post-LED strum stays E2 A2 E3 A3 C4 E4)

Low-battery shutdown below 6.2V with tip screen and 10s soft power-off; UI0902 includes LOWBAT_TIP fullscreen asset.

Stop all sound, show UI0902 LOWBAT_TIP fullscreen, then soft-off after 10s. Skip while charging; speed up ADC sampling near empty. Pack new tip bitmap into ExtFlash UI0902 map.

Disable LOOP_LIGHT rhythm chasing in free mode so LEDs stay solid green instead of moving with the beat.

Free-mode even-beat release stop; keep fret KEY_ID during wind-down so register octave does not jump up before stop. Also includes universal outro all-green LED and expert local-song continue after section+fret.

In normal mode, releasing the fretboard now finishes the current beat-pair (beat 1→end of 2, beat 3→end of 4) instead of cutting immediately.

Keep fretboard LEDs all green during outro, and for expert local songs treat section-key + fret changes as continuous chord updates like rhythm mode (no mid-session Stop).

Include Type-C charging battery icon and BLE timbre/style UI sync fix already on develop; add RTT midi/string inject helpers for mic pitch calibration. Tone pack remains 0916_bank.

App writes for timbre/BPM/transpose/style were refreshing LCD and
reloading tone packs on the 768B BLE recv stack, causing overflow and
crashes. Route heavy work through MSG_ID_BLE_* into the UI task, and
notify App when the device changes rhythm style.

Stop accompaniment on mode/song switch; restore all-green LEDs when leaving universal; default pick/preamble to current-key I chord after soft boot.

Apply Accomp_ApplyDefaultIChord before SyncStart on preamble, on soft power-on/mode enter/nav switch, and on pick fallback. Reset TM1629 key edge state so soft-off residual key_last cannot stick a prior fret.

Use Stop_AutoBand (engine stop + all-channel AllNotesOff) when changing nav mode, reloading tone presets, switching songs/progressions, or returning to mode select. Also fix AllNotesOff to address all 16 MIDI channels.

Consume the same power-key hold used for soft-off charge boot before setting powon, and ignore stale POWOFF_CHARG after power-on so mode select stays on screen.

Require fretboard in normal mode per manual; use SetPiecePlayMode for 1.bin. ACK ui boot/charge before full-screen draw, add RTT flash all and tone pick free, and skip soft-off while ExtFlash transfer is busy.

TMR7 high-prio watchdog and fault-loop emergency cut/reset so soft-off still works if the main loop or AutoBand ISR dies; skip start when preset load fails.

Require left-hand pad held (PressFlag) before pick starts; skip the default I-chord fallback in normal mode. Release (key 0) stops AutoBand immediately instead of looping.

Ignore TM1629 keys 0-21 in universal so pad no longer changes KEY_ID or arms OutTime_Stop; keep tap-tempo and stop. Clear stale KEY_ID/PressFlag when entering universal tab.

Exit piece mode before Postamble so universal chord loops can switch into the style outro stage once 3.bin has PostambleMIDI.

Bump firmware version after BT recv stack/log fixes and pitch/chord bounds so Phoenix Atelier map/LED traffic no longer stack-smashes the MCU.

Enlarge BT recv stack, move large handlers/log buffers off the stack, clamp key indexes, and yield in W25Q busy-wait so BLE protocol tests stay stable.

TaskBTRecvThread previously started only after mode select, so GATT SysEx never reached the parser until then; verified BLE-MIDI 01 01 now replies with GATT notify.
