/**
 * Triage Policy — PEAT-B1
 *
 * Pure policy evaluation for pre-diagnosis evidence triage.
 * No I/O, no plugin imports, no side effects.
 *
 * This module evaluates a TriageInput against source descriptors
 * and returns a TriageResult. The plugin adapter calls this function
 * and uses the result to decide whether to proceed to diagnosis.
 *
 * ERR checklist:
 * - ERR-001: No `as` casts. Input validated with runtime guards.
 * - ERR-002: Every result carries structured reason + nextAction.
 * - ERR-005: Input is unknown, validated field-by-field.

 * - Call PainDiagnosticGate
 * - Write to event log or trajectory
 * - Create diagnostic tasks
 * - Import anything from the plugin layer

 * It only reads source descriptors and applies policy rules.
