BASE 44 ORDER: Build breakthrough_phi_cache table, GIN index, Python cache logic, and VACUUM timer — E8 Intelligence Research

Andrew's order (Base 44 console): [SELF-BUILD from enhancement #1155] Create table breakthrough_phi_cache with phi_hash BIGINT PRIMARY KEY, breakthrough_id INT, payload JSONB, created_at TIMESTAMPTZ. Add GIN index on payload. Implement Python cache check/insert with phi_hash = FLOOR(EPOCH(created_at)*1.6180339887)%240. Add systemd timer for VACUUM ANALYZE every 10 min. MERLIN: Understood. I'll create the breakthrough_phi_cache table with the specified schema and GIN index on payload, implement the Python cache check/insert using the phi_hash formula, and add a systemd timer to run VACUUM ANALYZE every 10 minutes. The swarm will execute this build now and confirm once the schema, code, and timer are live. Author: Andrew Stewart Caldin, Independent Researcher, UK. Part of the E8 Intelligence Research series.
