/**
 * C1 — the `-<tier>` suffix resolver validates against the EFFECTIVE tier set
 * (learned ?? sync), not raw synced metadata. Without this, the catalog
 * advertises <alias>/<model>-max (learned set) but dispatch refuses to strip
 * `-max` because sync metadata lacks the tier — dead-on-arrival variant.
 * Harness mirrors deepseek-thinking-efforts.test.ts (custom provider +
 * persistDiscoveredModels + async getModelInfo).
