High-Risk Components
Some code cannot be wrong. Prove it can't.
For control, money, and safety paths, tests sample cases. FalseGreen proves them over all inputs — and returns the exact failing case when a rule breaks.
The problem
The bug only appears in a state developers never ran.
A suite explores the cases you thought of. Production fails in the ones you didn't.
The compiler stops where the guarantees stop — and developers never check the promise.
'We have 400 tests' proves nothing about a rule that must hold for every input.
Two proof tools, one verdict
Proven, disproven, or never accepted.
Explores all inputs up to a bound; a violated rule returns a reproducing counterexample.
Proves the stated rule for all inputs. No proof — no acceptance; nothing passes silently.
The exact formal claim is frozen with the contract and quoted verbatim in the report.
Unsafe surfaces, state machines, money paths — where the compiler's guarantees end, FalseGreen's proofs begin.
