In depth

Replaying a recorded run means re-running the simulation, which is far too expensive to do inside a frame and cannot be seeked into at all — an intent stream has no keyframes, so reaching tick 4,000 means running the four thousand before it. Running it once, up front, and keeping what each tick produced turns a replay from a simulation into a lookup.

A flat Float32Array of channels values per tick, plus one byte of flags for the booleans that would otherwise cost four bytes each. Preallocate with capacity when the length is known — a caller replaying a recording always knows it — and nothing reallocates while the simulation is running.
