# WSC module uses std::fs for file I/O (reading/writing snapshot files)
# This is intentional - WSC is for native tooling, not WASM determinism

# parallel exec uses std::env for feature-gated stride fallback (ECHO_PARALLEL_STRIDE)
# This is a build-time debug toggle, not runtime non-determinism
crates/warp-core/src/parallel/exec.rs
# engine_impl uses std::env for ECHO_WORKERS configuration
# This is read once at engine construction for worker count - determinism is not affected
# because the worker count doesn't change execution results, only parallelism level
crates/warp-core/src/engine_impl.rs
# Test file uses std::fs to read/write golden vector binaries for determinism verification
# This is test-only I/O, not simulation code — it validates determinism, not violates it
