- Markdown navigation checks cover inline/reference destinations, escaped/percent-encoded paths, heading markup and duplicates, same-document fragments, dirty target reuse, failed navigation atomicity, primary-only following, and `gf` prefix cancellation/configuration overrides.
- Jump-history checks cover cross-buffer/same-document navigation, search and picker recording, counts and repeated visits, bounded history, branch truncation, closed buffers, edited-coordinate clamping, dirty text/undo preservation, Ctrl+i/Tab aliases, and custom bindings. Real LSP fixtures cover definition round-trips and delayed replies after leaving and returning to the same source location.
- Session and Ruby checks exercise real Ruby execution, command/capability ownership, effect validation, configuration fallback, plugin retirement, crash/timeout recovery, and inherited-pipe cleanup.
- Unix terminal-hook checks use isolated child processes and real PTYs to keep process-global hooks out of the parallel runner. They cover cleanup on entry failure, normal return, I/O errors, and panics during synchronized redraw, including original panic-payload propagation.
- Unix terminal-hook checks use isolated child processes and real PTYs to keep process-global hooks out of the parallel runner. They cover raw/alternate-screen/mouse-capture cleanup on entry failure, normal return, I/O errors, and panics during synchronized redraw, including original panic-payload propagation.
- Redraw checks inspect actual Crossterm output during repeated scrolling: supporting terminals receive synchronized frames, terminals ignoring synchronization never paint with a visible hardware cursor, and the final caret remains visible.
- Wheel checks render document/panel views and cover three-row scrolling, unchanged carets/selections/text, first/last-page clamping, offscreen cursor hiding, no-op/custom-bound navigation reveal, manual persistence through idle/resize/palette updates, and floating/unfocused-docked explorer selection and focus preservation.
- Native LSP integration checks launch framed-protocol fixture subprocesses, covering initialization/settings, opt-in startup, synchronization, UTF-16/file-URI conversion, dirty targets, stale requests/diagnostics, and transport failures. Stack checks cover independent initialization, diagnostic merging/clearing, sibling failure isolation in active/parked buffers, same-revision rename/close identity, aggregate limits, first-server position routing, and both shutdowns. Semantic ordering uses protocol/file gates; elapsed deadlines only bound stuck subprocesses.
- Hover regression checks cover content forms, sanitization, cancelled/superseded replies, invalid results, scrolling/dismissal, Unicode clipping, and preserved editing state.
- Semantic-token checks cover full/range requests, legend/modifier remapping, UTF-16 boundaries and grapheme rounding, ASCII tab and Unicode column bounds, refresh/change coalescing, stale rename/close replies, null/empty/error fallback, primary/sibling retirement, and rendered cell precedence with syntax, diagnostics, search, selections, and carets.
