/**
 * Semantic tagging for Iranti knowledge facts.
 *
 * Assigns structured metadata (domain, intent, temporal scope, tags) to facts
 * at write time so retrieval can filter by semantic properties beyond pure
 * vector similarity. Every call to iranti_write that passes a durableClass
 * routes through buildSemanticFactTags() to enrich the stored properties.
 *
 * Key exports:
 *   - buildSemanticFactTags()  — produce the semantic properties block for a write
 *   - semanticMatchScore()     — score a stored fact against a SemanticFilter at retrieval
 *   - SemanticFilter           — structured filter passed to observe/attend for targeted injection
