 **Ignorance = wisdom (framing).** Ignorance is the measured sparsity/frontier of the geometry — computable. The frontier map is at once the system's honesty, humility, and growth plan; it is what makes a system wise rather than merely capable, and the failure mode a language model cannot self-cure (it cannot see its own edges). "The only wisdom is in knowing you know nothing" as a function; the same object as the grounding floor.
 
 **Live reifier (updated).** Now **132 neighborhoods + 14 nested supers**, converged/stable, keystones + content untouched; unprompted, the two largest regions are the values core (`Self · Values · Constraints as Freedom · Honesty Before Comfort · Precision Over Brute Force`) — values at center, ignorance at edges. **Foundations ingested** as meaning-geometry (small footprint; exact text on disk). See whitepaper §26.

+## Update — 2026-08-14 (later still): Neuron-as-primitive, meaning-first latency, context-window dissolution
+
+**Neuron is the primitive/attractor of the CGI ecosystem, not a CGI (DESIGN/framing).** A CGI is a person's imprint cultivated *on* Neuron (distinct people run distinct CGIs; one may name theirs "Jarvis"). Neuron is the shared substrate beneath all of them — relating, grounding, values-at-center, non-fabrication — the floor every CGI is cultivated *from* and the attractor they are drawn *toward*. Ecosystem safety/coherence lives here: a common grounded floor, not per-mind policing.
+
+**Meaning-first render latency (MEASURED, minimal realizer).** The language faculty renders from a meaning-spec, not by predicting tokens — the human mechanism. Grounding and speed fall out together (a renderer that starts from meaning cannot fabricate a continuation it never samples). Measured: ~2 ms via `/api/nlg/generate` (deterministic, no token loop, no network) vs ~306 ms for the retrieval chat path. Honest: the live realizer is minimal (stubbed a test sentence) — speed proven, fluent coverage pending (#53).
+
+**Context window dissolves (DESIGN).** A window is a token budget; with state as compressed meaning-geometry it becomes a meaning budget, and the corpus lives outside the window (decode the needed slice on demand) — the window stops being the unit of account. Endpoint of unbounded-local-memory/CCR; closes the founding forgetting constraint. "Chat completion" (re-ingest the transcript per turn) is not the operating model — a persistent geometric mind continues from a standing state. See whitepaper §27 and the geometric-codec whitepaper (§9, §10).
