# Rust composed exit and intermission state machine RE-843. Reproduce with `python3 scripts/analyze_rust_intermission_flow.py`; focused validation: `cargo xtask test-group rust-intermission-flow`. [Machine report](rust-intermission-flow.json). Rust composes recovered tie, readiness, begin and exit-log policies with prior exit timers/limits across150 continuous source fixtures. Atomic staged updates preserve shared pending/client state; reset and lower-level world/I/O effects remain explicit intentions. Source branch labels are independently classified by the tested composition oracle; captured requests and actual final source state supply effect parity. Original executable/native runtime and complete Linux/macOS Rust/Bevy/Solari acceptance remain unverified.
