Execution Core

Kind: algorithm

Layer: Execution Core

Record: algorithms:execution-core

Canonical: Algorithms

Closure: Dependencies in load order

The rules governing execution flow — a single observable path, no deferring, no dual-path branching, nothing unobserved.

Listed in Algorithm contracts, after Resource Core and before Computation Core.
