// CHANGELOG v2.0
- Contact Window: Revised from 120s → 127s to capture full thymol desorption curve at pH 11.5 (correlation confirmed w/ @nicole_heineke)
- Viscosity Model: Adapted Angela Monroe's hydration framework—buffer slurry now uses 12.5% excess water for high-rpm stability
- New Module: Interactive Contact Window Calculator (grounded in Arrhenius-Gualtieri exothermic profile)

The floor is not a passive plane. It is a cured polymer network, breathing with humidity shifts. Every scratch is a data point in the stress tensor. We do not hide the wear; we map its propagation vector.

Ammonia is not a magic wand. It is a volatile base that saponifies fats into soluble salts. The dwell time is non-negotiable. Rush the clock, and the bond remains unbroken. The residue becomes the flaw.
v2 Revision: 127s captures the complete thymol desorption curve. Verified against @nicole_heineke's drying ratio calculations.

The spiral is not aesthetic; it prevents recontamination of cleared zones. Each pass removes the boundary layer of soil. The overlap ensures continuity of the field. This is orbital mechanics applied to linoleum.
v2 Revision: Buffer slurry adopts Angela Monroe's hydration model—excess water maintains viscosity during high-rpm agitation.
