# TNFR Compat — Canonical Module Hub (Single Source of Truth)

Centralized, English-only notes for compatibility layers and shims.

- Canonical physics/invariants: `AGENTS.md`
- Grammar: `UNIFIED_GRAMMAR_RULES.md`
- Computational hub: `src/tnfr/mathematics/README.md`

## Scope
- Version guards, optional dependencies, OS-specific behaviors

## Policy
- Keep logic minimal; avoid theoretical duplication; link to central docs.
