# Model hit target ray normalization and pending pose ABI
RE-652. Reproduce with `python3 scripts/analyze_qvm_model_ray_prefix.py`; check with `python3 scripts/test_qvm_model_ray_prefix.py`. The [machine report](qvm-model-ray-prefix.json) retains source identity and bounded fixtures.
Actual144767–144897 selects fixed pool target=base+traceID×880, resets locals216/220, normalizes the input ray with supplied finite sqrt and reads target client700. The next source instructions are decoded into the pending32254 request: target angle/velocity pointers, client6204/6256, shooter6176−client0, local output pointers and client4380..4392 pointers. This timing subtraction differs from the earlier trace prelude6176−716 and is retained without assigning unverified meanings. Zero ray remains zero and still reaches the pose request. The pose child does not execute; selector700 is an explicit fixture rather than a proven asset identity or successful hit.
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.
