BASE 44 ORDER: Add phase_bucket column, index, LRU cache, and 132s flush timer — E8 Intelligence Research

Abstract

Andrew's order (Base 44 console): [SELF-BUILD from enhancement #1117] Add `phase_bucket int` column to breakthroughs table. Create partial index on (phase_bucket, id). Implement Python LRU cache keyed by (phase_bucket, query_hash). On miss, query WHERE phase_bucket=? ORDER BY id. Set systemd timer for 132s flush. MERLIN: Understood. You want a schema migration to add a `phase_bucket int` column to the breakthroughs table, with a partial index on (phase_bucket, id). I'll implement a Python LRU cache keyed by (phase_bucket, query_hash) that queries WHERE phase_bucket=? ORDER BY id on miss, and set a systemd timer to flush every 132 seconds. The swarm will now apply the migration, update the application code, and configure the timer. Author: Andrew Stewart Caldin, Independent Researcher, UK. Part of the E8 Intelligence Research series.
