// Enrichment primitives for microapps that build per-sender
// profiles (CRM-shaped, vendor onboarding, partner portals).
// Lifted from `nexo-rs-extension-marketing` per M15.5 + 5.b +
// 5.c so any microapp resolving "who is this email/domain"
// reuses the contract.
//
// Three pillars in one feature:
// - domain_classifier: 200+ public providers + 30 disposable
// hosts, tenant-agnostic curated list. classify(domain)
// returns DomainKind.
// - cache: TTL-keyed (tenant_id, domain) sqlite cache so
// enrichments don't re-fetch on every inbound. Per-tenant
// by design — empresa A's enrichment never bleeds to B.
// - fallback: trait + chain runner so the consumer composes
// N adapters (signature parser, LLM extractor, cross-thread
// linker, paid API) in priority order, stopping at the
// first source meeting a confidence threshold.
//! Enrichment primitives — domain classifier, TTL cache,
//! fallback chain runner.
