Interface Overview - Phylax Credible Layer Documentation

This page summarizes the public interface boundaries between Credible Layer components. It is intentionally high-level and does not expose internal endpoints or configuration details.

Interface Map

What Changes Require Coordination

Interface	Depends On	Coordinate With
CLI ↔ Platform API	Assertion submission and auth flows	Platform + CLI maintainers
Platform UI ↔ Contracts	Contract ABI + events	Platform + contracts maintainers
Platform UI ↔ Indexer	GraphQL schema	Platform + indexer maintainers
Enforcer ↔ Block Builder	Transaction validation hook	Network integrators
Enforcer ↔ Registry	Registry events + schema	Network + contracts maintainers
Enforcer ↔ Assertion DA	Bytecode storage API	DA + enforcer maintainers

Product and Protocol Boundaries

The Credible Layer combines protocol components with Phylax-operated product surfaces. This boundary matters when evaluating trust, availability, and operational ownership.

Component	Purpose	Layer
Credible Layer contracts	On-chain registry, protocol admin authority, assertion windows, and timelocks	Core protocol
Assertion Enforcer	Executes active assertions and returns inclusion decisions during block production	Network enforcement
Assertion DA	Stores assertion bytecode and source code for enforcers and public verification	Phylax-operated storage today
`pcl` CLI	Builds, tests, authenticates, and submits assertion releases	Local developer tooling
Backtesting	Tests a platform release against transactions from the last 20,000 blocks before deployment	Phylax-operated release review service
Staging	Runs assertions against live network activity without dropping transactions	Phylax-operated validation environment
Platform	Manages releases, invalidations, audit logs, collaborators, alerts, and project metadata	Phylax product

Guidance

Keep interface changes backward compatible when possible
If a breaking change is needed, update all dependent components in the same release window
Ensure public docs reflect any new interface expectations
