// This declaration is the SURVIVING SENSOR.HPP
// (410SRC/.../CODE/BT/BT/SENSOR.HPP) reproduced verbatim, with reconstruction
// annotations added in comments only.  The class body below is GROUND TRUTH;
// the @ADDR / @offset notes were recovered from the shipped binary and tie
// each declaration to the evidence used in sensor.cpp.
//
// Recovered binary facts (see sensor.cpp for per-method @ADDR evidence):
//   - Sensor IS-A PoweredSubsystem (powersub.hpp), object size 0x328.
//   - vtable @0050fb0c   ctor @004b1d18   dtor @004b1d90
//   - DefaultData @0050fa1c   ClassDerivations @0050fa2c
//   - AttributePointers @0050fa50  (three IndexEntry records, see below)
//   - RegisteredClass::SensorClassID == 0x0BC3  (resource +0x20),
//     streamed model size 0x190 (resource +0x24 -- same record as
//     PoweredSubsystem; the Sensor resource adds no fields).
//
//   IMPORTANT CONFLICT NOTE: the prior powersub.cpp/CLASSMAP reconstruction
//   labelled the class at vtable @0050fb0c / ctor @004b1d18 "Myomers" with
//   inferred members outputVoltage/powered/voltageAvailable.  That was a
//   misidentification.  The shipped attribute string pool (@0050fae0:
//   "Sensor", "RadarPercent", "SelfTest", "BadVoltage") and the surviving
//   SENSOR.HPP prove the class is Sensor.  classID 0xBC3 is Sensor, not
//   Myomers.  See CLASSMAP.md "Resolved conflict".
