/**
 * Platform ports contract — copied verbatim from the Bottom-Up Evolution Atlas
 * "Platform ports contract" TS block (the single source of truth).
 *
 * These describe the platform-governance fabric (Session/OPA/CMP/MDM/CRRE/SAS/
 * Capability) that OTHER teams own and that does not exist yet. IIOS consumes
 * them through this interface; in dev/test it binds to deterministic fakes
 * (@insignia/iios-testkit). In prod it binds to the real services. The kernel
 * never builds these — it only depends on the contract.
