# Source model bindings and original tag attachment evidence

RE-694. Reproduce with `python3 scripts/analyze_md3_bindings.py`; check with `python3 scripts/test_md3_bindings.py`. The [machine report](md3-bindings.json) retains source identity and bounded fixtures.

The source initializer executes with explicit captured loader/attachment bodies, retaining all arguments and global writes. Original files resolve uniquely under case-folded comparison. Both characters request lower→upper via tag_torso, upper→head via tag_head and head→helmet via tag_head. The16-byte selector table is mapped to original lower/upper/head/helmet roles. Every requested first-frame tag exists. The Orion lower suffix case mismatch remains recorded. This establishes source binding/tag evidence without yet asserting native loader ownership, heap allocation, actual attachment side effects or runtime path precedence.

No original executable/full QVM/native collision/physics/rendering executes. Native responses and legal input domains are supplied or unverified where stated; full runtime/macOS/Linux Rust/Bevy/Solari gameplay remains open.
