Fixes the crash the user hit twice today (captured in artifacts/coldeve-acceptance-20260729/crash-hunt.log): clicking into a multiline UiField - the examination window's inscription field - after the text had changed since the last draw threw an unhandled ArgumentOutOfRangeException from String.Substring and took the whole client down (UiField.MeasureRange <- HitChar <- OnEvent MouseDown). Root cause: _wrappedLines is a DRAW-side cache (rebuilt only in DrawMultiLine) consumed by the INPUT side (HitChar on MouseDown and drag-select MouseMove). Input events are pumped before the frame's draw, so a mutation (backspace, SetText, paste) followed by a click in the same pumped frame handed HitChar wrap lines describing the OLD, longer text; measuring those stale ranges ran past the end of the live string. Fix: text mutations now bump a version (the _text field became a private property so every existing mutation site participates without churn), the draw records which version its wrap lines describe, and HitChar proves coherence via EnsureWrappedLinesCurrent() - rebuilding with the last draw width when stale. Rebuilding rather than clamping keeps caret placement CORRECT against the live text, not merely non-throwing. Two inversion-sensitive regression tests reproduce the exact crash sequence (wrap long text, shrink without a draw, click); they throw without the HitChar coherence call. App tests 3,962 passed / 3 skipped (3,960 + 2 new). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |
