BASE 44 ORDER: Build e8_breakthrough_cache table with composite index and 24h TTL — E8 Intelligence Research

Andrew's order (Base 44 console): [SELF-BUILD from enhancement #1101] Create `e8_breakthrough_cache` table with columns e8_hash BIGINT, query_hash BIGINT, response TEXT, created_at TIMESTAMP. Add composite B-tree index on (e8_hash, query_hash). Modify agent to compute E8 hash before LLM call, check cache, store on miss with 24h TTL. Add daily cron to prune >7 days. MERLIN: Understood. I will create the `e8_breakthrough_cache` table with columns e8_hash BIGINT, query_hash BIGINT, response TEXT, and created_at TIMESTAMP, plus a composite B-tree index on (e8_hash, query_hash). I'll modify the agent to compute the E8 hash before each LLM call, check the cache, store on miss with a 24-hour TTL, and add a daily cron to prune entries older than 7 days. The swarm will execute this build immediately. Author: Andrew Stewart Caldin, Independent Researcher, UK. Part of the E8 Intelligence Research series. Platform: e8intelligence.com
