v0.1.3

Added

• BLE provisioning now fails on non-LR4 devices. The serial is validated up
  front (must be the LR4… form; normalized to the label's uppercase), and after
  connecting the provisioner verifies the device exposes the LR4 provisioning
  GATT service before writing anything — closing the --address path that
  previously accepted an arbitrary BLE address.

v0.1.2

Removed

• The clean-cycle command — the Home Assistant button, the CLI clean-cycle
  subcommand, and commands.clean_cycle(). A live capture proved the inherited
  0x02A30000 ("cleanCycle") opcode resets the robot (odometerPowerCycles
  increments, no cycle runs) — it was a reset disguised as a cycle, so it's gone
  rather than left shipping a surprise reboot.

Changed

• 0xA3 reclassified to never-send. It's the reset / main-board-OTA
  orchestrator, not a motor command; the safety guard now refuses it unconditionally
  alongside 0xA4 / 0xAC / 0xAD. No motor command is exposed until a real
  cleanCycle trigger is recovered — the MOTOR / allow_motor gate stays wired but
  empty.
• Documented the action-command hunt in docs/reverse-engineering.md: the
  0xA3 correction, why the cleanCycle / power / empty / reset dispatch lives in a
  bootloader region absent from every public OTA image, the exhaustive (and empty)
  search for a complete firmware dump, and the recovery paths (cloud-byte capture,
  app decompile, ESP-flash / PIC-ICSP dump).

v0.1.1

Fixed

• The signed macOS installer (Apple Silicon + Intel) now builds and ships;
  0.1.0 targeted the since-retired macos-13 runner image, so that release
  shipped without the macOS .pkg.

v0.1.0

Added

• whiskerless Python library — fully-local MQTT control + telemetry for the
  Whisker Litter-Robot 4:
  • LR4 wire codec, command catalog, and a typed state model that decodes both raw
    firmware integers and cloud-style strings defensively.
  • A push-first LitterRobot4Client with a self-healing MQTT connection and
    write → read-back → retry for the firmware's commit-latency registers.
  • Device-agnostic BLE (esp-idf protocomm) re-provisioning with a self-contained
    pure-Python protobuf codec (no protoc build step).
  • A safety guard that refuses brick/reset-class commands (0xAC/0xA4/0xAD)
    unconditionally and gates motor / untraced commands.
• whiskerless CLI — provision, monitor, state, read, set,
  clean-cycle, and a guarded raw send.
• Home Assistant integration (HACS) built to Platinum standards: fully async,
  fully typed, local_push, with MQTT discovery (robots appear as Add/Ignore
  cards), diagnostics, translations, and per-robot config entries (any number of
  robots).
• Documentation — protocol reference, register map, command catalog,
  compatibility matrix, setup guides, recovery guide, and the reverse-engineering
  writeup.
• Standalone CLI binaries built on release for users who want the BLE
  re-provisioner without installing Python.
