Two gaps left by the hover fix, both the same crash class. `grid_smart_range` indexes `grid[click.line]` the moment it starts — `hyperlink_run`, then `logical_line_at` — with the row a double-click carried in from the frame that dispatched it. That row can outlive its grid the same way a hovered cell can: a split, a window drag, or the reader thread applying the daemon's replayed attach geometry between paints. `Grid`'s `Index<Line>` only `debug_assert`s the bound, so a release build walks off the storage, and the click arrives in a gpui `extern "C"` callback where the panic aborts instead of unwinding. Guard the row up front, exactly as `TerminalView::grid_line` does. `set_grid_size` forgot the hovered *cell* but kept the link it had resolved. That link is stored in grid coordinates, so after the reflow it underlines whatever text now sits at those coordinates and holds the pointing-hand cursor over it until the pointer moves again — clamping's wrong-but-silent hover, one step removed. Drop it with the cell. Both halves get a regression test; the smart-select one panics on the storage `debug_assert` without the guard.

tty7
A terminal workbench: shells, sessions, SSH, coding agents.
Pure Rust · GPU rendering on Zed's gpui · VT core from Alacritty
English · 简体中文
Why
- Fast — ~2× the throughput of Alacritty, Ghostty, or Kitty (benchmarks)
- Sessions persist — quit or reboot; your shells keep running, no tmux
- Editor-grade input — completion, syntax highlighting, history search built in; zero config for zsh, bash, fish, PowerShell
- Agent-aware — recognizes Claude Code & co. in a pane: status, notifications, session resume
