Module runner 

The test runner: expands attacks (checks + fuzz mutations) into concrete tests and executes them, optionally across a pool of worker threads.

Functions

expand_all

Expand a list of attacks into concrete tests: check clauses become expectations, and each mutate generator becomes one or more variants.

expand_attack

Expand a single attack into one or more concrete tests.

run_all

Run all attacks (after expansion) and return their outcomes in order.
