BASE 44 ORDER: Implement embedding_hash partial index with 60° angle binning and TTL cache — E8 Intelligence Research

Andrew's order (Base 44 console): [SELF-BUILD from enhancement #1074] Add partial index on breakthroughs(embedding_hash) WHERE h+k+i=0. Modify agent to compute (h,k,i) via 60° angle binning. Query index before LLM call; store/retrieve responses keyed by (h,k,i) with TTL. Schedule weekly VACUUM ANALYZE. MERLIN: Understood. You want a partial index on breakthroughs(embedding_hash) for rows where h+k+i=0, plus an agent that bins (h,k,i) into 60° angles. The swarm will build the index, modify the agent to compute bins, query the index before LLM calls, and cache responses keyed by (h,k,i) with TTL. Weekly VACUUM ANALYZE will be scheduled.
