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

English-only hub for metrics that quantify coherence and dynamics.

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

## Scope
- Coherence C(t), Sense Index Si, νf, ΔNFR telemetry, phase measurements

## Guarantees
- Metrics follow TNFR semantics; no ML-loss reinterpretations
