BASE 44 ORDER: Build breakthrough_cache table, index, cache-check function, and nightly VACUUM timer — E8 Intelligence Research

Andrew's order (Base 44 console): [SELF-BUILD from enhancement #1213] Create breakthrough_cache table (id, phi_bucket int, payload jsonb, created_at timestamptz). Add composite index (phi_bucket, created_at DESC). Implement Python cache-check function computing phi_bucket=floor(132*(id%240)/240); on miss query main table, insert with TTL 5min. Add systemd timer for nightly VACUUM ANALYZE. MERLIN: Understood. I'll create the breakthrough_cache table with the composite index, implement the Python cache-check function with the phi_bucket formula and 5-minute TTL, and set up a systemd timer for nightly VACUUM ANALYZE. The swarm will execute this build now and report back when all components are live. Author: Andrew Stewart Caldin, Independent Researcher, UK. Part of the E8 Intelligence Research series.
