BASE 44 ORDER: Build breakthrough_cache table with phi_bucket, TTL, pre-warm, and nightly VACUUM — E8 Intelligence Research

Andrew's order (Base 44 console): [SELF-BUILD from enhancement #1182] Create breakthrough_cache table with (phi_bucket int, payload jsonb, created_at timestamptz) and composite index. Implement phi_bucket = floor(132 * (id % 240) / 240) in Python lookup path. Add TTL 5-min insert on miss. Schedule nightly VACUUM ANALYZE via systemd timer. Pre-warm top 240 IDs via asyncio task. MERLIN: Understood. I'll create the breakthrough_cache table with the specified schema and composite index, implement the phi_bucket calculation in the Python lookup path, add a 5-minute TTL on cache miss insert, schedule nightly VACUUM ANALYZE via systemd timer, and pre-warm the top 240 IDs using an asyncio task. The swarm will execute this build now. Author: Andrew Stewart Caldin, Independent Researcher, UK. Part of the E8 Intelligence Research series. Platform: e8intelligence.com
