WBV2 source dynamic inventory status

operation: BLENDER_52_SOURCE_DYNAMIC_INVENTORY; status: done
source authority: blender-5.2.0/source/blender; tree SHA: 600cb3dd441f09d9655b740735fbf8fa49ad6c14d308c68d59a29f9c338e4202
source scan: 6206 files, 96049182 bytes, 3745 deduplicated units
explicit coverage: verified 350, unverified 3395; this audit delta: 350
planning estimate: 5200 (non-binding); hard target: false
unverified boundary: operators 2012, operator-macros 58, nodes 476, RNA structs 785, modifier sources 64
boundary rule: no source-backed WebEngine route plus Chromium behavior receipt means the unit remains UNVERIFIED
historical 6900-entry parity map remains immutable and is retained only for regression provenance
cmd json transport: web_engine_call_json provides one stable Worker-to-WASM entrypoint for stateful commands and read-only reports; it reduces native registration points but does not replace per-unit Chromium evidence
headless boundary: blender-5.2.0/source/blender/web_engine/web_engine_headless_fallback.cpp records the intentional absence of window manager, desktop sequencer playback and GPU context for operator/macro execution
deterministic generator/checker: PASS
