# Trust lattice operations

Purpose
- Monitor and operate trust lattice gates for VEX and policy decisions.

Core components
- Trust vectors and gate configuration.
- Verdict replay for deterministic validation.

Monitoring
- Track gate failure rate, verdict replay failures, and trust vector drift.
- Use dashboards for gate health and override usage.

Common operations
- View current trust vectors and gate configuration.
- Inspect a verdict and its trust inputs.
- Trigger manual calibration when required.

Emergency procedures
- High gate failure rate: pause dependent workflows and investigate sources.
- Verdict replay failures: verify inputs, cache epochs, and policy versions.
- Trust vector drift: run replay with frozen inputs and compare hashes.

Maintenance
- Daily checks: gate failure rate and queue depth.
- Weekly checks: trust vector calibration and drift review.
- Monthly checks: update trust bundles and audit logs.
