//! Sources of non-determinism the workspace consumes: the wall clock and the random number generator. Both have
//! mockable variants so a deterministic-simulation run replaces them with seeded equivalents and reproduces the
//! same trace bit-for-bit. Anything in the workspace that needs the time of day or a random value reaches for
//! these handles instead of pulling from `std`.
