/**
 * @fileoverview Trust Bus enums for cross-layer governance propagation.
 *
 * This module is a **zero-dependency leaf**: it must contain no imports
 * (especially not `zod` or `drizzle-orm`) so that enum-only consumers —
 * signal producers, adapters, and analytics layers — can import the wire
 * enums without pulling any runtime dependency into their module graph.
 * The Zod schemas that previously lived here are in `trust-bus-schemas.ts`.
 *
 * `BusSeverity` and `BusSignalType` are the **frozen wire surface** shared
 * with `@vorionsys/rainbow` and the rainbow-interop harness. Member names
 * and string values are the contract; changing either breaks every consumer
 * comparing against these values. The guard test
 * `tests/canonical-trust-bus.test.ts` pins the exact member sets.
 *
 * The signal schema is open-source (Apache-2.0). The Bus Router that routes
 * and correlates these signals is an AgentAnchor Pro/Enterprise feature.
 *
 * @see {@link trust-bus-protocol-v0.md} for the full protocol specification
 * @module @vorionsys/contracts/canonical/trust-bus
