Constants

MIN_COMPLEXITY

below this we don’t trust a match, thunks and tiny leaves all look alike

SAME_THRESH

two prints this close are “the same function”

Functions

dump_traces

debug helper: micro-execute one named function and return its effect traces (one per seed/path). used by fnprint dump to see what the engine records.

eval

rank every signal-bearing function in A against all of B, using symbol names as ground truth. this is the headline accuracy measurement.

index_bytes

micro-execute + fingerprint every discovered function in an ELF blob.

index_to_db

match_by_name

align two indexes by symbol name and report which shared functions actually changed behavior. this is the “what did the vendor quietly patch” view.

query_corpus

for each function in the target that we can trust, pull the best-matching named function out of the corpus db. withholds tiny/low-signal functions.

source_str

triage

rank each target function against a known-vulnerable corpus and a known-patched corpus and call which side it leans to. a function close to the vulnerable version and clearly separated from the patched one is a candidate worth a human’s time, which is more useful for n-day work than a single match score.

warm_pool

Force the rayon global pool to spawn its worker threads now. The sandboxed worker calls this before it jails itself, so the jail can forbid clone/clone3 (no thread creation after lockdown) without starving the parallel index.
