`simvx.core.scene_io`¶

Scene I/O — parso-based round-trip parsing and editing of scene .py files.

Tier 1 (source_tree) provides the lossless parse/dump primitive; Tier 2 (edits) provides prefix-preserving editing primitives that operate on the parso tree returned by Tier 1. Tier 3a (emitter, detection) provides greenfield Python emission for live node trees and lightweight scene-file detection.
