# Heuresis Protocol Resolve an underexpanded candidate field through frame-parallel divergent generation, without ever eliminating, ranking, or selecting among the candidates it produces. Type: `(CandidateFieldUnderexpanded, User, DIVERGE, IdeationRequest) → DiverseCandidateField`. ## Definition **Heuresis** (εὕρεσις): the act of finding or discovering[^1] — a dialogical act of widening a candidate field that is empty or has prematurely converged, before any selection is made. Divergent and convergent thinking are distinct cognitive operations (Runco & Acar, 2012), and no protocol in this catalog carries a typed guarantee to generate the object-level alternative set itself — the nearest neighbor, `/preview`, activates only once two or more candidates already exist and their futures are unrecognizable from description; heuresis sits upstream of that, at the point where the field itself is thin. On a blank entry, heuresis opens an abstract frame map before showing any concrete idea — early concrete examples measurably narrow independent generation (Wadinambiarachchi et al., 2024), and ideating before seeing material preserves ownership and diversity that seeing it first does not (Qin et al., 2025). Generation is frame-parallel and never eliminates, ranks, or scores: selection is a downstream act, out of this protocol's scope. [^1]: Greek εὕρεσις denotes finding, discovery, or invention/conception broadly; its later specialization as a term of rhetorical inventio is one hist...
