ContextReadymade takes the found situation — street, bar, institution, classroom, square or platform — as matter already charged with meaning. GrammaticalThreshold marks the point where that matter ceases to be anecdote and enters its own grammar, capable of repetition without losing singularity. HybridLegibility ensures that this grammar can be read by humans, archives, search engines and models. The triad explains how a situated gesture becomes an operator. It is not enough to indicate a context; the context must cross a formal threshold. Then the situation becomes legible without being simplified. Socioplastics is born in this friction between the found and the structured: it converts the available world into operative language.
