Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to The PR adds broad deterministic UI testing and related TUI fixes, but the current changes can still panic during Preferences focus handling and dispatch stale footer mouse actions after a view change; one test can also hang instead of reporting a regression.

Centralize the picker-construction branch.
This Some(source) => with_memory_source / None => new selection is duplicated in crates/skit-tui/src/session.rs (handle_add_event, add-overlay construction). A future change to memory-backed construction must then be applied twice. Add one constructor on FilePickerSession that accepts the optional source, and call it from both sites.

Merge the two hit loops to remove the duplicated click derivation.
Both loops iterate geometry.hits, apply the same zero-area skip, build the same left-click event, and call expected_hit_action with the same arguments. The click formula therefore exists twice. If one copy changes, the map_event check and the session check compare different cells, and the parity guarantee weakens without a test failure.
Keep the bounds check first inside a single loop, then run the session parity work with the click and expected values already computed.

Extract one artifact-writing helper.
write_failure_artifacts and write_success_artifacts repeat the same sequence: create the directory, stage a tempdir_in with a dot prefix, write the cast, write repro.json, call keep(), strip the leading dot, and rename. Only the prefix, the cast file name, and the JSON body differ. The staging and atomic-rename logic is the delicate part, and a correction applied to one copy will not reach the other.
Extract a private helper that accepts the prefix, the cast file name, the cast bytes, and the already-built JSON value, and let both functions call it.

Anchor this regression test to the dropdown state it protects.
The four operations select commands and hits by ordinal. choose in strategy.rs maps each ordinal modulo the live command or hit list, so the selected command changes whenever a UiCommand spec is added, removed, or reordered, or whenever a screen enables a different command set.
The only assertion is walker.liveness_checks == walker.checkpoints().len(). That equality holds for any trace in which every checkpoint forked a probe. It does not prove that the trace opened the Run dropdown. If the inventory shifts, this test keeps passing and stops covering the occluded-field-command defect it was written for.
Add assertions that pin the reached state, as the sibling tests at Lines 2028-2039 and 2076-2086 do.

🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win
Assert the mapped action, not one hard-coded chord.
The test name promises that no shared key selects quit. The assertion only compares the generated chord against Ctrl+C. If UiCommand::Quit gains a second binding, or if another command's binding maps to Action::Quit, this loop still passes. resolve already exposes the semantic check through map_event, so assert on the action instead.
♻️ Proposed stronger assertion

- (key.code, key.modifiers),
- (KeyCode::Char('c'), KeyModifiers::CONTROL),

Bound the focus search.
At Line 338, the loop does not terminate if AddControlId::Candidate(_) is absent from focus traversal. CI then hangs instead of reporting the routing regression. Limit the number of Tab events and assert that the candidate received focus.
Proposed fix
- while !matches!(session.focused(), Some(AddControlId::Candidate(_))) {
+ for _ in 0..32 {
+ if matches!(session.focused(), Some(AddControlId::Candidate(_))) {
+ break;
+ }
assert_eq!(
session.handle_event(
Event::Key(KeyEvent::new(KeyCode::Tab, KeyModifiers::NONE)),
@@
Some(AddScreenEvent::Changed)
);
}
+ assert!(matches!(
+ session.focused(),
+ Some(AddControlId::Candidate(_))
+ ));📝 Committable suggestion

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Target the existing text field.
registry_states() creates one run-form field at index 0. Line 988 uses field 1, so map_event returns None because the field does not exist. This test does not detect a regression that treats a choice hit on the existing text field as a focus action.

Summary
Design note
The issue proposes
proptest-state-machine. This implementation uses plainproptestwith late-bound semantic operations. The state-machine crate generates its transition list from an abstract reference state before it executes the system under test. It cannot bias each next event from the liveLibraryState, persistentTuiSession, and latestViewGeometrywithout either duplicating the reducer or reducing transitions to late-bound selectors. A plain shrinking vector preserves the live-state design, avoids a second model that can share the product bug, and still produces a minimal replay.The driver observes the motivating bug class before it services the host effect. It renders and checks
ConfirmDraftDelete(true)while the delete request is still in flight.Validation
