v2.5.0

Added

• Independent Caps Lock LED and Keyboard Brightness toggles. The
  Reactions group renders two separate accordion cards instead of one
  bundled "Keyboard" card, and the per-event matrix in Stimuli has a
  dedicated column per output (KbBright + Caps). Each output is gated
  by its own LEDOutputConfig flag inside LEDFlash.action so a user
  can enable the keyboard backlight without firing the Caps Lock LED,
  or vice versa. The Keyboard Brightness card hides on hosts where the
  backlight isn't available (Mac mini, Mac Pro, etc.).
• Per-model coverage tables in every sensor source header.
  LidAngleSource.swift, GyroscopeSource.swift,
  AmbientLightSource.swift, and HeadphoneMotionAdapter.swift now
  document expected reach across M1 → M4 silicon and headphone models.
  The runtime probe is the source of truth; the tables are the
  documentation.

Changed

• Lid angle now reads the dedicated Apple lid HID device, not the
  SPU IMU stream. Vendor 0x05AC, Product 0x8104, UsagePage
  0x0020, Usage 0x008A, Feature Report 1 polled at 30 Hz,
  decoded as UInt16 LE whole degrees from bytes [1..2]. The previous
  SPU usagePage 0xFF00 / usage 8 subscription was decoding
  uninitialized tail bytes — the IMU report is exhausted by accel/gyro
  at offsets 6/10/14, with no lid channel anywhere in the buffer. M2
  Pro/Max, M3 family, and M4 family laptops have the dedicated device;
  M1 (any), M2 base MBA / 13" MBP, and every desktop have either no
  device or no IMU silicon at all, and the toggle hides accordingly.
• Ambient light corrected from usage 7 to usage 5. The M4 Max
  ioreg dump and AsahiLinux's reverse-engineering both confirm ALS
  rides on usagePage 0xFF00 / usage 5. The 7 was a guess that
  worked only because the SPU broker fans every report regardless of
  usage tuple — usage 7 does not exist on the SPU bus.
• Gyroscope and ALS gain App Store sandbox parity with the
  accelerometer. isAvailable now combines device presence with a
  runtime activity probe via _last_event_timestamp on the
  dispatchGyro and dispatchAls services respectively. On Direct
  builds the probe is bypassed (the unsandboxed process can write the
  activation properties directly); on App Store builds the probe must
  report fresh-streaming for the toggle to surface. A one-shot
  activelyReporting= log fires at every source start so silent
  failures are visible in the audit log.
• yamete-sensor-kickstart now activates gyro and ALS alongside
  accel. The helper previously short-circuited the
  AppleSPUHIDDriver iterator on dispatchAccel, leaving the gyro
  and ALS kernel-driver instances silent on App Store builds. The
  iterator now walks every service flagged with any of
  dispatchAccel, dispatchGyro, or dispatchAls and writes the
  activation triplet to each. Existing helper installs need a one-time
  sudo ./install.sh to pick up the change.
• AccelHardware.isSensorActivelyReporting is now parameterised
  over dispatchKey so gyro and ALS can mirror the accel probe.
  The probe also no longer bails on the first stale sibling — it
  scans the entire AppleSPUHIDDriver iterator and returns true if
  any matching service is fresh.

Fixed

• Lid sensor no longer fires nonstop LidSlammed reactions. Field
  audit logs from this release showed 3 500+ lidSlammed events per
  hour with physically impossible angles (-322°, -244°, etc.) — the
  consequence of the offset-18 garbage decode driving the slam-rate
  state machine into a loop. The dedicated-device rewrite produces
  real angles in the [0°, 180°] range, and a defensive sanity gate
  rejects anything outside that envelope.
• keyboardBrightnessEnabled is now wired into pipeline rebuilds.
  Previously the impact pipeline's shouldRun predicate did not list
  keyboardBrightnessEnabled, so flipping it on alone (with every
  other output off) would not start sensors. The setting is now
  observed by Yamete.startSettingsObservation and included in
  rebuildSensorPipeline.shouldRun.
• 40 lprojs synchronised with the new keyboard/Caps Lock string
  keys. setting_led_enabled, setting_keyboard_leds,
  help_keyboard_leds, and legend_led are dropped (replaced by
  setting_keyboard_brightness, setting_caps_lock_led,
  help_keyboard_brightness, help_caps_lock_led,
  desc_caps_lock_led, legend_keyboard_brightness,
  legend_caps_lock). Non-en locales receive English copy as a
  fallback for translator follow-up.
