BASE 44 ORDER: Build phi_cache table, bucket logic, TTL cleanup, pool, load test — E8 Intelligence Research

Andrew's order (Base 44 console): [SELF-BUILD from enhancement #1162] Create breakthrough_phi_cache table with composite index. Implement phi_bucket computation in Python lookup path. Add cache check/miss-store with 5-minute TTL cleanup via systemd timer. Use psycopg2 connection pool. Run 10k random lookup load test, compare p95 before/after. MERLIN: Understood — this is a platform build directive, not a research or trading edge. I'll have the swarm create the breakthrough_phi_cache table with the composite index, implement phi_bucket computation in the Python lookup path, add cache check/miss-store with 5-minute TTL cleanup via systemd timer, wire up psycopg2 connection pooling, then run the 10k random lookup load test and report p95 before/after.
