| # Rust begin-intermission state and effect intentions | |
| RE-839. Reproduce with `python3 scripts/analyze_rust_intermission_begin.py`; focused validation: `cargo xtask test-group rust-intermission-begin`. [Machine report](rust-intermission-begin.json). | |
| Rust matches 39 original begin-transition cases, preserving timestamp guard semantics, fallback IDs, entity-client field clear and preparation/slow/respawn/move/publication order. Native work stays typed effects; invalid counts reject before mutation. | |
| Original executable/native runtime and complete Linux/macOS Rust/Bevy/Solari acceptance remain unverified. | |
