Exact proposition
The formal statement is part of the acceptance target.
Formal verification
Proof evidence with a fixed obligation.
Lean is a first-class formal proof evidence backend for FalseGreen Jobs.
A human or model may write a proof. The Lean kernel checks the proof. FalseGreen decides whether the exact frozen formal obligation was satisfied by the exact source under the declared trust boundary.

What is bound
Formal evidence is only as strong as its declared boundary.
FalseGreen records the proposition and declaration, source context, toolchain, dependency identity, and the evidence required by the frozen Job. A proof hole or sorry is not silently treated as a completed obligation where the Job policy rejects it.
Kernel checked
Lean checks proof correctness under the declared environment.
Source identity
The result belongs to the exact source and declaration verified.
Toolchain identity
Compiler, Lean version, and dependencies are evidence context.
No magic guarantee
FalseGreen does not prove arbitrary mathematics or open problems.
Honest outcomes
Missing or insufficient evidence remains a non-accepted result.
The acceptance role
Lean checks the proof. FalseGreen accepts the Job.
Formal tools are evidence witnesses inside the acceptance platform. FalseGreen remains responsible for deciding whether the evidence establishes the frozen requirements, whether the source identity matches, and whether the result is durable and inspectable.
