The candidate emergent state is a growing spatial-temporal correlation or traveling pattern among otherwise modest local deviations, followed by corresponding gradients in post-dry binder or carbon-binder distribution on witness samples.","consequence":"If the pattern is not recognized until endpoint inspection or cell testing, a coating lot may contain compositionally nonuniform regions that complicate adhesion, conductivity, electrochemical consistency, disposition decisions, and diagnosis of the drying process.","affected_objective":"Maintain compositionally uniform dried electrode coatings while preserving defensible lot-disposition and process-adjustment decisions.","intervention":"Run a shadow-mode sensing workflow that aggregates contextualized temperature, optical, and dielectric traces across web position and dryer time. Compare their spatial-temporal relationships with recipe-specific baseline variation, surface candidate segregation patterns with explicit uncertainty, and route them to human review. An ambiguous pattern triggers targeted witness sampling; a corroborated harmful pattern can support a quality hold and a separately authorized review of drying conditions.
