# Entity initializer and preserved record fields

RE-604. Reproduce with `python3 scripts/analyze_qvm_entity_init.py`; check with `python3 scripts/test_qvm_entity_init.py`. The [machine report](qvm-entity-init.json) retains source identity and bounded fixtures.

Actual instructions 277126–277162 set record532=1,536=97243 (`noclass`),540=3226498489,0=(pointer−34091368)/880 and512=1023. The wrapper stops before the void PUSH/LEAVE epilogue. No memset occurs here: stale client pointers, positions, callbacks and free time survive this initializer. The fixed source pool base and 880-byte stride are retained. Eighteen fixtures cover slots 0,63,64,65,1022,1023 and three complete-record canaries; independent tests compare all 220 words. Allocation callers must establish any clearing policy separately.

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.
