## Editorial Policy & AI Transparency

LawnMowerSpecs enforces strict human-in-the-loop technical verification. All torque specs, fluid capacities, gap tolerances, and part crossover tables are cross-referenced directly against OEM Factory Workshop Service Manuals (Kohler, Kawasaki, Briggs & Stratton, Honda, Toro) and statutory standards (OPEI / ANSI B71.1, SAE J1349). Algorithmic tooling is utilized solely for data indexing and formatting under master technician supervision.
