BASE 44 ORDER: Build breakthrough phase cache and wire ingestion + lookup — E8 Intelligence Research

Andrew's order (Base 44 console): [SELF-BUILD from enhancement #1340] Create table breakthrough_phase_cache (id BIGSERIAL, phase_key TEXT, bucket_id INT, payload JSONB, created_at TIMESTAMPTZ DEFAULT now()). Add composite index (bucket_id, phase_key). Modify breakthrough ingestion to insert 3 rows per phase_key (bucket_id = h%240, (h+1)%240, (h+2)%240). Update Python lookup agent to query cache before LLM, write on miss. MERLIN: Understood. I'll create the breakthrough_phase_cache table with the composite index, modify ingestion to insert 3 rows per phase_key using bucket_id = h%240, (h+1)%240, (h+2)%240, and update the Python lookup agent to check cache before calling the LLM and write on miss. The swarm will now implement and deploy this enhancement. Author: Andrew Stewart Caldin, Independent Researcher, UK. Part of the E8 Intelligence Research series. Platform: e8intelligence.com
