Desktop click-to-position-cursor died under the server's mouse-DECSET strip
(same root cause as the mobile touchend tap regression): xterm's native mouse
encoder only emits SGR while mouseTrackingMode is ON, but the server strips the
enabling DECSETs from claude/codex/gemini output. Hand-encode the report for
plain left-clicks (_handleDesktopTerminalClick), skipping every click that
already means something else (synthetic/compat, modified, double/triple,
drag-selection, off-grid, xterm encoder live).
Also widen forwarding to the wheel: Claude Code 2.1.187+ scrolls its own
transcript on SGR wheel reports and no longer captures wheel as select-menu
navigation (verified against 2.1.202), so forward the wheel to the TUI for
strip-mode sessions at the buffer bottom (40ms-coalesced to avoid a tmux
send-keys storm). Shift+wheel and any scrolled-up viewport stay on xterm's
local scrollback. Guard synthetic taps/clicks on viewport-at-bottom so a
scrolled-up report can't hit-test the wrong row.
Tests: 12 cases in test/terminal-touch-tap.test.ts. Verified E2E via Playwright
against the live instance (wheel up/down forward, Shift+wheel local, click).
v1.1.7 (3172bef, arrived via the master merge) strips mouse-tracking DECSET
sequences from claude/codex/gemini output so the wheel keeps scrolling
scrollback. Side effect: the browser xterm's mouseTrackingMode is permanently
'none' for those sessions, and the mobile touchend tap branch gates its
synthetic click on exactly that mode — so tap-to-position-cursor silently died.
Fix: when tracking reads 'none' but the session mode is one the server strips
(claude/codex/gemini — the PTY-side TUI still has tracking ON), encode the SGR
press+release report directly from the touch point and send it to the PTY,
bypassing xterm's mouse encoder. No DOM click is dispatched, so xterm's local
selection cannot trigger either.
Tests: 3 new cases in test/terminal-touch-tap.test.ts (SGR encoding, grid
clamping, shell-mode exclusion); verified E2E via Playwright iPhone emulation
against both a stripped-stream instance and the production bundle.
