Strategic pivot from seconds-horizon ES order-book RL (measured structurally
unprofitable) to diversified days-to-weeks multi-asset ML trend. ML as bounded
deviations from a deterministic diversified-trend floor; gated by CPCV/PBO/
Deflated-Sharpe. Phase 0 (build+validate the floor on Databento micros, CPU-only,
no ML, no cluster) is the immediate decisive test. Synthesizes 8-agent omnisearch
research (pearl_surfer_universe_build_synthesis).
