III-VII shapes use the C-major sequence column with the same fixed-key offset as the strings. Chord tones follow the decimal column. Bump firmware to 0.2.57.

A protected pack only trickle-charges, so Dream, the 12V rail, and the amp stay off until the pack is above 6.8V. Firmware is 0.2.51.

Show the real battery percent, shut down at 6.8V even while Type-C is connected, and leave the charge screen dark so it does not drain the pack. Initialize the amplifier only after the 12V rail has settled.

Match the card box to the reference, put the value on the same center line as the arrow and plus-minus chips, and use MiSans for the 16px digits.

Centralize idle-timer reset on touch/volume/tap/transpose in UI task, and on pick, fretboard, side keys, round keys, and string NoteOn. Pause auto power-off countdown while accompaniment is playing.

Restore hard AutoBandTop1_Stop and drop eaten-start/followup tick-gate.
Keep API stubs for callers. Block TM1617 round keys and reinforce side-key/BLE gates while InModeFlag is false.

Universal TM1629 path dropped keys 0-21 before BP_Transpose. Route pick-hold neck keys to transpose, add RTT pick hold inject and a HIL script.

TM1617 keys injected fake touches at y=255 which slammed mixer sliders to 1. Lock the pressed fader until release and shrink overlapping hit boxes.

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.

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.

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.

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.

tools/k1_harness: one CLI over existing COM/BLE/RTT scripts covering
App SysEx 01-06, BLE smoke, TM1629/TM1617 key inject, 1/2/3.bin pack
checks with pick/outro regression, and UI nav (log status/TAP/DUMP).
Unified PASS/FAIL/SKIP/SENT markdown report to Doc/reports.
firmware hooks in app_log.c: 'tm1617 key N', 'adc key N on|off',
'tone bin2 [idx]', 'chord key N hold' (sticky inject survives physical
idle scan so normal-mode pick tests can hold a chord).

AutoBand ignores input octave, so shift engine MIDI output by -12 for those chords (except drums) to keep the range from low #IV up to natural IV.

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.

Log Flash magic on load failure, expose RTT flash bin3, and document the 0903 pack offset for the universal bank.

Always Send_volume in MainTask, re-apply after DSP settle, and sync vol_last so UI bar matches Dream gain.

Pick fires on downstroke; #IV drops an octave; local songs use 2.bin; transpose updates notes without restart; intro starts on key I; boot string volume/PC corrected.

Harden reset/recover when RTT is missing, and stream touch/UI events only on press for field debugging.

Preserve focus across redraws, improve XPT2046 sampling, and log touch coords via RTT for ongoing debug.

Replace the old volume bars with 5 rounded-top bars using a left-to-right brightness gradient, synced from the ADC volume pot.
