2026-08-10 (P2 of the Quant Research Factory roadmap) -- runs
services/formula_composer_service.py's small-scale combinatorial
strategy scan (35 candidate combinations of 6 existing causal
indicator primitives, each walk-forward-validated) against `ticker`
and returns the top out-of-sample survivors. See that module's
docstring for the full methodology and why this stays deliberately
small rather than an exhaustive/genetic search.
