charset=UTF-8 Content-Transfer-Encoding: 8bit Blocking: 1. Add smart-metadata-v2, vector-search-cosine, context-support-e2e to npm test chain (package.json) 2. Rewrite smart-metadata-v2.mjs to import production code via jiti (normalizeContext, parseSupportInfo, updateSupportStats, etc.) 3. Rewrite vector-search-cosine.test.mjs to use real MemoryStore against temp LanceDB (no more fakeStore) Suggestions: 4. Fix '下午' mapping: evening → afternoon (add to vocabulary) 5. parseSupportInfo: validate slice numeric fields (confirmations, contradictions, strength, last_observed_at) 6.
