BASE 44 ORDER: Build breakthrough cache with SHA-256/phi_bucket, LLM check/upsert, 30-day cleanup timer — E8 Intelligence Research

Andrew's order (Base 44 console): [SELF-BUILD from enhancement #1279] 1. Create table breakthrough_cache with schema per idea. 2. Implement SHA-256 hash and phi_bucket computation in Python. 3. Add cache check before LLM and upsert after response. 4. Add systemd timer for cleanup of entries older than 30 days. MERLIN: Understood. I will create the breakthrough_cache table with the schema from enhancement #1279, implement SHA-256 hashing and phi_bucket computation in Python, wire the cache check before LLM calls and upsert after responses, and add a systemd timer to purge entries older than 30 days. The swarm will now execute this build and verify the service restarts cleanly.
