BASE 44 ORDER: Add compression_score column, partial index, and gated LLM calls in gtx_scout — E8 Intelligence Research

Andrew's order (Base 44 console): [SELF-BUILD from enhancement #1366] Add compression_score float column + partial index to breakthroughs table. In gtx_scout forwarder, compute Jaccard/n-gram overlap vs last 200 same-division breakthroughs plus 20-window coil score; gate LLM calls on compressed AND novel threshold; log gated calls. MERLIN: Understood: this is a self-build directive from enhancement #1366 targeting the breakthroughs table and the gtx_scout forwarder. The swarm will add a compression_score float column plus a partial index to breakthroughs, then in gtx_scout compute Jaccard/n-gram overlap against the last 200 same-division breakthroughs alongside a 20-window coil score. LLM calls will be gated on both a compressed AND novel threshold, with all gated calls logged for later review. Author: Andrew Stewart Caldin, Independent Researcher, UK.
