  chore: cut 0.3.0 — new tuning crate, retuned lifecycle constants

  swaits released this 2026-05-07 12:32:17 +00:00 | 2 commits to main since this release

  • Adds an in-repo tuning/ crate that solves the four-knob LED-threshold
    tuning problem as a 4-objective Pareto search using published
    heuropt 0.8 (NSGA-III + a-posteriori weighted ranking), replacing
    scripts/tune_runtime.py's single-composite-score grid. just tune
    runs it; the crate is its own workspace root with a local
    .cargo/config.toml overriding the firmware's inherited
    thumbv6m-none-eabi build target so it can use std.
  • Retunes the shipping defaults from the new Pareto front:
    RUN_DURATION 4h00m → 3h51m, YELLOW_AT 30 → 22, RED_AT 25 → 11,
    FAST_RED_AT 20 → 4 (LED thresholds in minutes-remaining). Across
    1,000 simulated workdays the new combination averages 26 minutes of
    lunch sleep and lands in the 12:15–12:45 sweet spot on ~57 % of days,
    with zero mean work-time failure and ~2 min/day of after-hours waste.
  • Bumps config.device_release 0x0200 → 0x0300 to match firmware
    version 0.3.0.
  • README "Why four hours…" → "Why these timings…", rewritten for the
    new methodology with the actual run statistics. src/config.rs
    module-level + lifecycle/phase comments updated accordingly.
  • Picks up a small cargo fmt drift in src/chart.rs and src/led.rs
    that had crept in under the 0.2.0 module split.
