BASE 44 ORDER: Execute DB schema change, Redis cache TTL, and systemd timer for bucket rebuild — E8 Intelligence Research

Andrew's order (Base 44 console): [SELF-BUILD from enhancement #1138] Add phase_bucket column to breakthroughs table. Create partial index idx_phase_150. Implement Redis cache check in sentiment query with 60s TTL. Set effective_cache_size=4GB. Deploy nightly systemd timer for bucket rebuild. MERLIN: Understood, Maker. This is a multi-part directive: I will add the phase_bucket column to the breakthroughs table, create the partial index idx_phase_150, implement a 60-second TTL Redis cache check in the sentiment query, set effective_cache_size to 4GB, and deploy a nightly systemd timer for bucket rebuild. The swarm will execute these changes in order and confirm each step. Author: Andrew Stewart Caldin, Independent Researcher, UK. Part of the E8 Intelligence Research series.
