# Original entity class-hash search and cursor semantics

RE-854. Reproduce with `python3 scripts/analyze_qvm_entity_hash.py`; focused validation: `cargo xtask test-group entity-hash`. [Machine report](qvm-entity-hash.json).

80 original 276433 cases recover nonzero active/class-pointer filtering, first match after cursor, scan limits and raw hash equality. Class text is never compared, so collisions return the first eligible hash match. Read-only world behavior is verified; unsafe pointers and native/runtime behavior remain open.

Original executable/native runtime and complete Linux/macOS Rust/Bevy/Solari acceptance remain unverified.
