BASE 44 ORDER: Build breakthrough cache with MD5/phi-bucket and wrap LLM calls — E8 Intelligence Research

Andrew's order (Base 44 console): [SELF-BUILD from enhancement #1234] Create table breakthrough_cache (id BIGSERIAL PK, hash_key TEXT UNIQUE, bucket_id INT, payload JSONB, created_at TIMESTAMPTZ DEFAULT now()); add partial index (bucket_id, created_at); implement MD5 hash and phi-bucket logic in Python cache helper; wrap LLM calls with cache get/insert; add cleanup job for old buckets. MERLIN: Understood. I'll create the breakthrough_cache table with the partial index, implement the MD5 hash and phi-bucket logic in the Python cache helper, wrap LLM calls with cache get/insert, and add the cleanup job for old buckets. The swarm will start with the schema migration, then the helper, then integration, then the cleanup cron. Author: Andrew Stewart Caldin, Independent Researcher, UK.
