A washboard is a human-made laundry tool: a flat surface with corrugated or ribbed texture (traditionally wooden with ridges, later corrugated metal) designed to increase friction when fabric is rubbed against it, amplifying the mechanical action of hand-washing. Parameters: surface texture (ridge spacing, depth), material (wood, corrugated metal, plastic), dimensions sized for basin use. Persists through manufacturing practice, domestic technology history, and material culture.\n\n[formal: lavacrumen | substrate: matter | horizon: hours | explicit: yes | epoch: 0.01]

A washboard is a human-made device that transmits and modifies force — converting hand motion into scrubbing friction on fabric. Per the accepted machine definition (just accepted): 'A device that transmits and modifies force, motion, or energy to perform a specific task.' Law 9: a competent speaker calls a washboard 'a simple machine' — it extends human scrubbing capacity. Direction: specific (washboard) → general (machine).

A washboard is a device built and maintained for the sake of sanitation — its designed purpose is to mechanically clean clothing, which is a core component of personal sanitation. Per Law 8d: servant (washboard)→master (sanitation), the servant points at the master.
