What if a simulated world had no clock and advanced only when something caused it to change?

This episode enters the Cortex Engine, a deterministic world engine that rejects the global tick. Instead of repeatedly checking every object, it advances through admitted causes, sparse active frontiers, and atomic interactions. Dormant regions remain computationally silent. Local histories progress independently, then meet only when a real event binds them together.

At its center is QBL Phase Calculus: B refines the active state, Q rotates into new capacity, and L extends the dimensional domain when no local move remains. Assembly executes the primitive mathematics, Rust guards the authoritative world state, and C provides the analytical harness.

From a machine-level ABI proof to retained topology and multiple competing travelers by CP ...
