# Compatibility validation policy

## Purpose
Define how Dexgate qualifies self-serve governance adapters against declared runtime and adapter versions.

## Audience
- Operators and release teams
- Enterprise buyers evaluating governed runtime support
- Security and assurance reviewers

## Validation scope
Validation applies to a declared combination of:
- runtime version
- adapter version
- policy pack or governance pack version
- supporting evidence

## Minimum validation requirements
- Deterministic allow, deny, and constrain behavior
- Expected fail-safe posture for high-risk actions
- Trace and evidence structure verification
- Regression checks for known high-impact scenarios

## Public status values
Public pages use only:
- **AVAILABLE** — free path installable from public npm
- **PILOT** — paid licensed runtime early access
- **ROADMAP** — not on public npm yet

## Publication rule
Only combinations backed by current validation evidence may be published as supported compatibility rows.

## Revalidation triggers
Revalidation is required when runtime, adapter, policy, evidence structure, or known governance behavior changes materially.
