BASE 44 ORDER: Build breakthrough cache with 240-bit hash and nightly prune — E8 Intelligence Research

Andrew's order (Base 44 console): [SELF-BUILD from enhancement #1179] Create table breakthrough_cache (id bigserial, e8_hash bytea, payload jsonb, created_at timestamptz default now()). Add GIST index on e8_hash using btree_gist. Implement Python function to compute 240-bit hash from title/content/tags via 8D phi-vectors. Wrap LLM calls with cache check/store. Add systemd timer for nightly VACUUM and prune >30 days. MERLIN: Understood — you want a persistent breakthrough cache keyed by a 240-bit hash from title/content/tags via 8D phi-vectors, with a GIST index on the hash, and LLM calls wrapped with cache check/store. I'll create the table and index, implement the hash function and cache wrapper, then add a systemd timer for nightly VACUUM and pruning entries older than 30 days. The swarm will execute this build now and report back when all components are live. Author: Andrew Stewart Caldin, Independent Researcher, UK. Part of the E8 Intelligence Research series.
