Touch drags and flick momentum on forwarding-capable sessions (codex,
claude >= 2.1.187) now go to the CLI as coalesced SGR wheel reports via
the shared _forwardScrollToApp helper, exactly like the desktop wheel:
snap the viewport home first, then encode. Before this, every phone or
tablet swipe scrolled the local buffer of stale repaint frames and
dragged the CLI's pinned input box off the screen (the mobile half of
issue #205). The _shouldForwardWheelToApp gate is shared, so the
local-scrollback opt-out setting and the CLI version gate apply to touch
exactly as they do to the wheel; shell and other local modes keep the
existing local touch scrolling and the scroll-to-top history re-pull.

Reported against the beta: scrolling up in a Claude session drags the prompt
box and status line up the screen along with everything else, and only once
the local buffer hits its top does the CLI's own history start moving.
_shouldForwardWheelToApp() gated forwarding on the viewport being at the buffer
bottom, so that leaving the bottom handed the wheel back to local scrollback and
both histories stayed reachable. Two things make that the wrong default:
- A repaint-mode CLI keeps no terminal scrollback of its own (tmux reports
history_size=0 for a Claude pane), so xterm's buffer holds only Codeman's
REPLAYED repaint frames. Scrolling those locally moves the CLI's pinned
furniture and shows stale frames underneath.
- scrollToLastNonEmptyLine() parks the viewport `rows - 2` above the last
non-empty row, so any session with trailing blank rows was left off-bottom
and every later wheel event went local without the user ever scrolling.
Forward unconditionally for the verified modes instead, and snap the viewport
back to the bottom before encoding the report (SGR coordinates address the live
screen, and forwarding while the user stares at stale scrollback looks dead).
Shift+wheel and the "Wheel scrolls local history" opt-out still reach local
scrollback.
Verified against a real Claude 2.1.223 session: wheel-up scrolls its transcript
back 48 lines (rows showing 85-92 -> 37-44) while the input box, separator and
status line stay fixed at the bottom.
Deterministic claude --version probe seeds cliVersion so wheel-forwarding
to Claude's transcript engages (banner scrape was unreliable on 2.1.187+
and resumed sessions). Shift+wheel reads the dominant axis so a trackpad's
horizontal Shift-scroll reaches local scrollback. New per-device
"Wheel Scrolls Local History" opt-out. Wheel reports use a fire-and-forget
send path so they no longer flicker the pending-bytes indicator.

- _shouldForwardWheelToApp: claude sessions forward wheel to the TUI only
when the banner-parsed cliVersion is known AND >= 2.1.187 (older/unknown
Claude Code captures wheel as select-menu navigation → keep local
scrollLines); new dependency-free _cliVersionAtLeast semver-ish compare
- gemini excluded from wheel forwarding entirely (TUI wheel behavior
unverified); codex keeps forwarding (verified); taps/clicks still
forwarded for all strip modes
- link double-fire: registerFilePathLinkProvider links now track hover
state via ILink hover/leave callbacks (_linkHovered) and
_handleDesktopTerminalClick bails while a link is hovered, so a link
click no longer also sends a synthetic SGR press/release to the TUI
- help modal: document Shift+Wheel (scroll local history when mouse
passthrough is active)
- tests: version gate (2.1.186/unknown/garbage no forward, 2.1.187+
forwards), codex/gemini split, link-hover click suppression

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.
