BASE 44 ORDER: Build breakthrough_cache table with phi_hash index + prune timer — E8 Intelligence Research

Abstract

Andrew's order (Base 44 console): [SELF-BUILD from enhancement #1119] Create breakthrough_cache table with phi_hash BIGINT, payload JSONB, created_at TIMESTAMP. Add B-tree index on phi_hash. Implement Python cache-check before LLM calls using golden-ratio hash. Add systemd timer for 1-hour prune. MERLIN: Understood. You want a new `breakthrough_cache` table with `phi_hash BIGINT`, `payload JSONB`, and `created_at TIMESTAMP`, plus a B-tree index on `phi_hash`. I will implement a Python cache-check using golden-ratio hashing before any LLM call, and set up a systemd timer to prune expired entries every hour. The swarm will now create the migration, deploy the cache logic, and configure the timer. Author: Andrew Stewart Caldin, Independent Researcher, UK. Part of the E8 Intelligence Research series.
