+# Extraction model
+
+Extraction nodes contain actual engine match/capture values and ranges. The
+syntax tree supplies capture names and parent relationships; engine results
+supply participation, value and offsets.
+
+Statuses distinguish:
+
+- participated with non-empty text;
+- participated and matched empty;
+- did not participate;
+- unavailable range;
+- preview-truncated value.
+
+Exact match and capture ranges are retained even when a displayed value exceeds
+the 64 Ki UTF-16 per-value preview limit or the shared 8 Mi-unit preview
+budget. Consumers must inspect the preview status rather than treating a
+preview as complete. In particular, list export is disabled if its template
+would consume an incomplete value.
+
+Repeated ECMAScript captures expose only the final retained capture. The UI
+labels this limitation and does not invent history. Later .NET support may add
+actual engine capture-history nodes without degrading them to this model.
+
+The syntactic hierarchy remains useful even if actual spans overlap or fall
+outside a parent's geometry; native and normalized ranges are preserved rather
+than “fixed”.
