Skip unchanged plaintext URL hit tests.
When Ctrl or Super is held and the pointer resolves to a live, unscrolled cell without OSC 8 ownership, each tick snapshots the owner grid and scans the pointer’s row before the idle short-circuit. A snapshot can clone up to 1,000,000 cells. A fully quiet window has no repeated timer ticks without a pending deadline, but animation wakeups can run this path every 16 ms.
Resolve the current pointer target, then skip the snapshot and row scan only when the owner view, cell, grid generation, and scroll state match the cached key. Grid changes must trigger a re-scan so a newly written URL appears under a stationary pointer. Do not skip only when no URL is hovered; that misses newly appearing URLs.

Require a matching Ctrl+left press before opening a plaintext URL.
When Ctrl is held and the left press starts outside a plaintext URL, the press starts a selection. If the pointer then moves onto a URL, release clears that selection and queues the URL for activation. Record the URL under the press and activate only when the paired release is over the same URL; otherwise, let the release complete the selection.

Sync the plaintext cursor after each runtime tick.
When PTY output removes a hovered URL, AboutToWait polls that output and then calls drive_tick(). Runtime::tick() revalidates hover and can switch the runtime icon to Text, but sync_plaintext_cursor() runs before the event-specific branch. The window can keep Pointer until another event. Sync the cursor immediately after Runtime::tick().
Suggested fix
let stats = self.runtime.tick();
+ self.sync_plaintext_cursor();

Review comment at @crates/bitty-terminal/src/terminal_app.rs around lines 1785 -
1793:
Call sync_plaintext_cursor immediately after Runtime::tick() in drive_tick so
the OS cursor reflects hover changes caused by each runtime tick.

Summary
Wires the
bitty-url-detectormatcher (detect_urls, v0.0.1, zero-dep,forbid(unsafe), git-rev5c65773— same pin convention asbitty-ipc/bitty-network-wire) into the sameValidatedUrl+ActivationGesturepipeline as OSC 8:detect_urls, maps byte offsets to columns via char indices (ASCII matches are 1 col each; preceding multi-byte scalars shift bytes past columns).Ctrl/Cmd+LeftClick mints the single-use gesture; plain releases keep selection meaning and never arm links. OSC 8 keeps current behavior (no Ctrl gate change — owned by [P1] OSC 8 hyperlink click-to-open live UX with hover feedback and TUI interception (R-005) #1759/PR [CTX-1006] OSC 8 hyperlink click-to-open live UX with hover feedback and TUI interception (R-005) #1771); where both claim a cell OSC 8 wins.Shiftforces selection.Ctrl-gatedhovered_plaintext_url(distinct from [CTX-1006] OSC 8 hyperlink click-to-open live UX with hover feedback and TUI interception (R-005) #1771hovered_hyperlinkto avoid duplication) drivesCursorIcon::Pointer/Text(change-gated OS call, new sharedCursorIconidentical to [CTX-1006] OSC 8 hyperlink click-to-open live UX with hover feedback and TUI interception (R-005) #1771) and a theme-foreground underline bar.
