Proto, salesman, and PP samples answer different questions. Treat wash approval as a path with stage goals—not a single vague “OK.”
Stage intent (buyer literacy)
- Proto: direction and major construction/wash intent
- Wash lock samples: sealed shade/hand/dry map as required
- PP: confirms bulk readiness against sealed standards
Exact sample counts, fees, and calendars are confirmed in quotation—not listed as site-wide promises.
