Native Dialog Responsiveness Evaluation

Date: 2026-07-12 Branch: codex/non-blocking-native-dialogs Implementation commits: d038cf3 and the closing commit for Gitea #52

This record captures live acceptance for the non-blocking native-dialog broker. The permanent workflow contract lives in the native-dialog guide.

Live Editor Evidence

The native KDE portal Open dialog below was launched through the production SceneIoRequest::Open path in a native Wayland debug editor and held open for 12 seconds.

During the hold, Hyprland continued to report Blacksite as mapped, visible, input-capable, and native Wayland. No application-not-responding client appeared. Cancel closed the picker without changing the active scene, and the editor then stopped cleanly.

Acceptance Results

Area	Result	Evidence
Frame responsiveness	Pass	A blocked-dialog regression test advances eight Bevy frames before releasing the worker; live editor remained compositor-responsive during the 12-second picker hold
Shared coverage	Pass	Every rfd::FileDialog and rfd::MessageDialog construction is inside a NativeDialogBroker::request worker closure
Request exclusivity	Pass	Focused test rejects a second request while one is pending and permits work after one-shot completion
Cancellation	Pass	Live Open cancellation preserved the active scene; workflow callbacks retain explicit non-mutating cancel branches
Main-thread application	Pass	Paths/results cross the broker, while scene, asset, history, registry, project, and collaboration work remains in &mut World completions
Stale initiating state	Pass	Prefab/export completions reject missing initiating entities; composition validates against current state after selection
Packaged acceptance	Deferred	Explicitly deferred by project-owner direction; no packaged result is claimed here

Automated Verification

Command/suite	Result
cargo fmt --all -- --check	Pass
cargo check --workspace --all-targets	Pass
cargo clippy --workspace --all-targets -- -D warnings	Pass
cargo test --workspace	Pass
Focused native-dialog lifecycle and frame-progress tests	2 passed
git diff --check	Pass
