v1.0.3

1.0.3 (2026-11-04)

Fixed

• Restore refuses a sleeping dynamic body that moves. The engine
  never writes a dynamic body that is asleep with a linear or angular
  velocity other than +0.0, but m3World_Restore used to accept one
  in a forged or damaged snapshot. The restored body then reported its
  velocity while asleep and resumed it when woken, where a body put to
  sleep through the API starts from rest. Restore now refuses such a
  snapshot with m3_errorFormat and leaves the world as it was,
  comparing each component bit for bit, so a -0.0 is refused too.
  Every snapshot the engine writes restores as before, and the check
  leaves stepping as it was.

• Restore refuses a static or kinematic body that sleeps. Only a
  dynamic body falls asleep: create and every type change wake a body,
  and m3Body_SetAwake refuses any other type. m3World_Restore used
  to accept a forged or damaged snapshot with a sleeping static or
  kinematic body. It now refuses one with m3_errorFormat and leaves
  the world as it was. Every snapshot the engine writes restores as
  before, and the check leaves stepping as it was. A 1.0.2 snapshot
  steps to the same bits, so 1.0.3 restores it.
