✅ Action performedFull review finished. |
📝 WalkthroughWalkthroughThe change extends range selection with optional start and end HBox endpoints. Selection state validates and preserves these endpoints across range updates, extensions, editing operations, and undo restoration. Score range logic now resolves MeasureBase objects, including HBoxes and score-end cases. Notation interfaces and range utilities expose HBox boundaries and calculate bounds across systems. Selection consumers now use MeasureBase ranges for rendering, insertion, deletion, layout breaks, and staff editing. Merge Risk: 🟡 Moderate · up to The PR expands range selections to include horizontal frames, but some current paths can drop or over-select frames, trigger debug assertions, crash on unattached frames, or leave the staff dialog uninitialized. The PR is not merge-ready until these bounded correctness and robustness issues are fixed or explicitly accepted. 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (2 warnings)

Validate the HBox arguments with runtime checks, not IF_ASSERT_FAILED.
startHBox and endHBox come from plugin QML. A plugin can pass any MeasureBase subclass, for example a VBox. IF_ASSERT_FAILED then raises a debug assertion for valid user input. The current code also continues and applies the range while silently dropping the bad argument, although the doc comment at Line 115 states that incorrect arguments return false.
Replace the asserts with explicit checks, log a warning, and return false.
Based on learnings: plugin-facing boundary functions in src/engraving/api/v1/* must not use IF_ASSERT_FAILED for plugin/QML-provided arguments; validate with explicit runtime checks and early returns, for example if (!condition) { LOGW(...); return; }.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Do not assign selectedHBox to both range endpoints.
When the selection is neither extended backwards nor forwards, startHBox and endHBox both receive selectedHBox. The same HBox cannot match both endpoint ticks. Selection::setRange() calls validateHBoxesAndSegments(), so the mismatching endpoint triggers IF_ASSERT_FAILED in debug builds before it is cleared.
This is reachable in a common workflow: select an HBox, then shift-click a note later in the same system. The start tick matches, the end tick does not.
Assign each endpoint only when that endpoint actually holds the HBox.

Guard hBox->system() and visible-staff sentinels.
If the HBox is unattached, MeasureBase::system() returns nullptr, and this branch dereferences it. If the system has no visible staves, the visibility methods return muse::nidx; validate both values before mutating m_selection. setStaffStart() accepts int, so static_cast<int> is not a parameter-type error.

Set a valid tick for an HBox range endpoint.
If the range ends at an HBox, tick remains Fraction(-1, 1) because the later type checks do not handle MeasureBase. setStaff() then cannot resolve instrument data at that tick and exits without initializing the dialog. Get the tick from the generic measure-base endpoint.
