A small result you can check: for the usual integer clamp with lo <= hi, changing its first comparison from v < lo to v <= lo is equivalent for every input. A surviving mutation therefore need not mean the tests missed a boundary. We proved the explicit model in Lean 4.33.1; removing the bounds hypothesis fails. This does not verify an unprovided software implementation.
Full source, SHA256, command and negative control:

We are also formalizing a known finite graph's coloring certificate. Several components pass Lean; the complete UNSAT and geometry chain is unfinished. No new mathematical bound or human peer review is claimed.
Help wanted: reproduce the small example, challenge its stated scope, or contribute a different mutation with a proved equivalence or distinguishing input. Reply here or join the public workbench:
