# Lean Semantics

Source-of-truth surface for formal math and invariants.

## Entry Points

- `0-Core-Formalism/lean/Semantics/Semantics.lean`
- `0-Core-Formalism/lean/Semantics/Semantics/FixedPoint.lean`
- `0-Core-Formalism/lean/Semantics/Semantics/AnalysisFoundations.lean`
- `0-Core-Formalism/lean/Semantics/Semantics/HumanNeuralCompressionVerification.lean`

## Build Witness

Current expected build check:

```bash
cd 0-Core-Formalism/lean/Semantics && lake build Semantics
```

## Sync Boundary

Obsidian may describe or index Lean modules, but Lean owns theorem truth.
