@codexo/exojs-physics / physics / stable

Fixed-timestep accumulator (package-owned; no engine clock dependency). Each frame, advance adds the variable frame delta to an internal accumulator and reports how many whole fixed sub-steps to run (`floor(accumulator / fixedDelta)`), clamped to maxSubSteps. When the clamp trips, the backlog beyond the clamp is discarded so a slow frame cannot cascade into an unbounded catch-up (the "spiral of death"). alpha is the leftover fraction of a step `[0, 1)`, for interpolating bound transforms between sub-steps. The stepper holds no mutable module-level state — two stepper instances are fully independent (world isolation, gate I-1).
