janikandClaude Fable 5 7f8672d7b9 GUI: live STM32 telemetry + sweep guards + auto-logging + bench-plot 
- stm32_link.py: port to the live 114-byte broadcast protocol (magic
  0xAA55AA55, odd parity 8-O-1, 100 Hz publish, repetition-validated,
  no CRC); 39 params incl. adc4_trig_phase/iin_zero_sum, CLEAR_FLAGS,
  30-bit flag table; commands stay CRC-16 framed; Telemetry aliases
  BroadcastData, efficiency uses iout_slow and eff_net subtracts P_sys
- gui_workers.py: STM32Worker reader thread with counter dedup, rate/
  loss counters, 20 s graph history, full-rate telemetry CSV writer
- gui.py: right-side telemetry panel (link state, power + EFF net,
  heatsink/board temps, Vfly group, control, HRTIM, status-flag
  checkboxes, fault registers), Vfly + selectable corr/phase-ofs
  graphs, 20 s rolling window on all plots, dual CSV logging (merged
  stm_* columns + <stem>_telem.csv), logging on by default into
  logs/data_<timestamp>.csv, Plot Eff button
- sweep guards: PSU 20 A input-current gate (conservative estimate +
  measured backstop + I-limit clamp), thermal pause at 57/77 C holding
  the load at 1 A until cooled 5 C below threshold, CC range pinned to
  R2 for the whole run with empirical range-max readback rejection
- plot_eff.py + bench-plot entry point: efficiency vs Vin vs current
  maps from any logged CSV (sweep / data log / telem autodetect), file
  dialog when launched without args
- bench.py: HIOKI FAST response speed, 5 s settle defaults; cli.py
  stm32-read prints the full broadcast; README + .gitignore updates

grabowskiandClaude Opus 4.6 956be4b77a Add shade profiles, 2D V×I sweep, meter format toggle, ON/OFF indicators, and GUI console 
- Shade profile: CSV-driven irradiance/voltage sequences with load control
  (bench.run_shade_profile, CLI shade-profile command, GUI profile panel)
- 2D sweep: voltage × load current efficiency map with live graph updates
  (bench.sweep_vi, CLI sweep-vi command, GUI sweep panel with background thread)
- GUI: meter format selector (scientific/normal), supply/load ON/OFF indicators,
  console log with stdout redirect and color-coded messages
- Sample profiles: cloud_pass, partial_shade, intermittent_clouds

grabowskiandClaude Opus 4.6 e55caa59b1 Initial MPPT testbench: unified CLI for IT6500D + Prodigit 3366G + HIOKI 3193-10 
Combines three instrument drivers (as git submodules) into a single
testbench for MPPT tracker efficiency testing. Features:
- Voltage sweep and load current sweep with CSV export
- Auto-range aware meter polling (waits for HIOKI to settle)
- Supply keepalive during long meter waits to prevent USB-TMC timeouts
- Live monitoring with real-time 4-panel matplotlib graphs
- Safe shutdown (load first, then supply)
- Post-sweep returns to 75V idle with supply ON
