BASE 44 ORDER: Build breakthrough_cache table with BRIN index and systemd VACUUM timer — E8 Intelligence Research

Andrew's order (Base 44 console): [SELF-BUILD from enhancement #1189] Create breakthrough_cache table with hash_key bigint, payload jsonb, BRIN index. Compute blake2b 64-bit hash of title+content. Implement cache check before LLM, store on miss. Add systemd timer for VACUUM ANALYZE every 5 min. Pre-warm 132 partitions via hash_key % 132. MERLIN: Understood. I will create the breakthrough_cache table with hash_key bigint and payload jsonb, add a BRIN index, and compute blake2b 64-bit hashes of title+content for cache lookups before LLM calls, storing on miss. I will also set up a systemd timer to run VACUUM ANALYZE every 5 minutes and pre-warm 132 partitions via hash_key % 132. The swarm will execute this build now and report back when the schema, indexing, and timer are live. Author: Andrew Stewart Caldin, Independent Researcher, UK.
