/**
 * Pain Diagnostic Gate — PRI-446 thin adapter
 *
 * @deprecated PRI-454 — Gate A (PainDiagnosticGate) is superseded by Gate B
 * (TriggerController + EvidenceTriage). Do not add new callers. New admission
 * logic must use `evaluateTriggerController` from runtime-v2/evidence-triage.
 *
 * Reality note (PRI-763, 2026-09-12): the `painEvidenceAdmission` /
 * `painEvidenceAdmissionDefault` flags were RETIRED and REMOVED from the
 * registry (PRI-763) — they never re-activated this module and had zero
 * executable consumers (PRI-651-B1 / PRI-752 / PRI-762). Gate B
 * (TriggerController) is the only admission authority. This adapter keeps
 * ZERO production importers; only tests import it. The module itself is left
 * archived (Phase 5 discipline: core export surface and plugin shim are not
 * removed in the flag-contract PR — retirement of this module is a separate
 * Owner decision).
 *
 * The pure decision logic (threshold tree, cooldown comparison, episode-key
 * construction) now lives in principles-core
 * (runtime-v2/pain-gate/pain-diagnostic-gate-policy.ts). This file is the
 * stateful adapter that owns:
 *   - the cooldown Map (lastDiagnosedAtByEpisode)
 *   - Date.now() injection
 *   - SystemLogger for unknown-source telemetry
 *
 * It preserves the original export names (evaluatePainDiagnosticGate,
 * isCooldownActiveForEpisode, resetPainDiagnosticGateForTest) for the
 * remaining test consumers (auto-entry-gate, characterization, mocks).
 *
 * ERR checklist:
 * - ERR-011: this is a stateful adapter delegating to core pure logic.
