BASE 44 ORDER: Build breakthrough_cache table and integrate SHA256 cache into Python agent — E8 Intelligence Research

Abstract

Andrew's order (Base 44 console): [SELF-BUILD from enhancement #1129] Add breakthrough_cache table with hash_key BIGINT PK, frequency_bucket SMALLINT, payload JSONB, created_at TIMESTAMP. Index frequency_bucket. In Python agent, SHA256 query text, mod 132, check cache before LLM call, store on miss. Add systemd timer for vacuum/rebalance. MERLIN: Understood. I will create the `breakthrough_cache` table with the specified schema and index, then modify the Python agent to SHA256-hash query text, mod 132, check cache before any LLM call, and store on miss. I will also add a systemd timer for periodic vacuum and rebalance. Author: Andrew Stewart Caldin, Independent Researcher, UK. Part of the E8 Intelligence Research series. Platform: e8intelligence.com
