Scroll was wired to GCMouse's scroll dpad, which only fires for plain HID wheel
deltas — trackpad and Magic Mouse scrolling are gesture events that never reach
GameController, so scrolling was dead on the default Mac setups. The stream view now
overrides scrollWheel (while captured the cursor is parked mid-view, so it receives
every scroll event) and feeds InputCapture.sendScroll: precise gesture deltas are
pixels (~0.1 notch/px, SDL's factor → ×12 for WHEEL_DELTA(120)), classic wheels are
lines (×120), fractional remainders accumulate, and the GC scroll handler is gone so
wheel mice can't double-deliver. Signs pass through as-is, preserving the local
(natural-)scrolling preference.

Capture used to engage whenever the app became active, so the click that activates the
window — on the title bar (a drag) or a resize edge — got the cursor warped away
mid-gesture, and raw deltas kept streaming to the host while the user fought the window.
Reworked Moonlight-style, with capture as a deliberate, reversible state owned by
StreamLayerView:
- Engage: automatically once when the stream starts / trust is confirmed (one-shot, can
never fire surprisingly later), or by clicking into the video (that click's
press/release are suppressed toward the host; acceptsFirstMouse makes it one click
from another app). NEVER on app re-activation.
- Release: ⌘⎋ (toggles, key-window-scoped), focus loss — now including same-app window
switches (⌘, / ⌘N / ⌘M resign key without resigning the app; previously the new
window inherited a hidden frozen cursor and its typing was double-delivered to the
host) — and disconnect.
- While released: nothing is forwarded (InputCapture.forwarding gates the GC handlers;
held keys/buttons are flushed host-side so nothing sticks), the cursor is free, and
the HUD (now showing the capture state) is clickable.
- The no-beep behavior moved from the NSEvent monitor to first-responder key
consumption — swallowing at the monitor risked starving GC's own delivery (the
"input broken altogether" report). The monitor now only intercepts ⌘⎋.
- Adversarial-review fixes: a second session preempts the previous one cleanly instead
of leaving it captured with dead GC handlers (onPreempted); the engage click's
suppression latch can't outlive the click (mouseUp backstop); ⌘⎋'s physical Esc can't
type into the host in either toggle direction (suppressedVK latch + Esc-while-⌘
guard); capture callbacks defer out of the SwiftUI update pass.
Validated live against the box: 16185 input datagrams injected during a captured
session (gamescope EIS), title-bar drag/resize free while released, and visible
cursor + typing on a streamed KWin desktop, all user-confirmed.

The app grows from a dev connect form into a real client shell:
- Home is a grid of saved hosts (UserDefaults-persisted; context menu: Remove / Forget
Identity), "+" in the toolbar opens the add-host sheet, the stream mode moved into
Settings (⌘, / gear) — native resolution stays the only mode, no scaling.
- Trust is now explicit: the protocol always supported certificate pinning, but the app
passed no pin and discarded the observed fingerprint — silently trusting any host.
First connect now shows the host's SHA-256 fingerprint (compare with the "clients pin
this fingerprint" line in the host log) over the live-but-blurred stream; the stream
must pump immediately (the opening IDR is the only guaranteed one), so StreamView gains
a capturesCursor switch to keep the cursor free while the prompt needs clicking, and
input capture starts only after confirmation. Trusting pins the fingerprint per host;
a changed host identity then refuses to connect.
- PUNKTFUNK_AUTOCONNECT keeps working (auto-trusts, doesn't touch the saved hosts).
Host→client authorization (pairing PIN) remains a punktfunk-core roadmap item — the host
still accepts any client that can reach its port.

The host renders its own cursor from our raw deltas, so the local macOS cursor both
stays visible and drifts away from the remote one — and it can wander out of the window,
where a click focuses another app. While the stream has focus, do what Moonlight does:
warp the cursor mid-view, disconnect it from mouse movement
(CGAssociateMouseAndMouseCursorPosition(false) — GCMouse still delivers raw HID deltas),
and hide it. Released on app deactivation (Cmd+Tab is the escape hatch), view teardown,
and disconnect; re-captured when the stream regains focus. The HUD's Disconnect gains ⌘D
since a hidden, frozen cursor can't click it.

Full project rename, decided 2026-06-10:
- Crates/binaries: punktfunk-core / punktfunk-host / punktfunk-client-rs.
- C ABI: punktfunk_* symbols, Punktfunk* types, include/punktfunk_core.h,
PUNKTFUNK_FEATURE_QUIC guard (header regenerated; cbindgen renames updated, incl.
PUNKTFUNK_BTN_*/PUNKTFUNK_AXIS_* wire constants).
- Protocol: punktfunk/1 — control-plane magic LMN1 → PKF1, nonce salt lmn1 → pkf1.
WIRE BREAK: clients must be rebuilt from this revision.
- Env knobs: PUNKTFUNK_VIDEO_SOURCE / PUNKTFUNK_COMPOSITOR / PUNKTFUNK_ZEROCOPY / ….
- Host config dir: ~/.config/punktfunk (the box's dir was migrated in place — the
persistent identity is unchanged, pinned fingerprints stay valid).
- Swift package: PunktfunkKit + PunktfunkCore.xcframework + PunktfunkConnection
(Sources/PunktfunkClient app + tests renamed with it); build-xcframework.sh updated.
- scripts/: 60-punktfunk.rules, punktfunk-host.service; OpenAPI doc regenerated.
Also: scripts/headless/run-headless-kde.sh — full headless Plasma bringup. Root cause of
"desktop but no apps/settings" over the stream: plasmashell launched without
XDG_MENU_PREFIX=plasma-, so the launcher resolved a nonexistent applications.menu and
rendered an empty menu. The script sets the complete KDE session env (menu prefix,
KDE_FULL_SESSION, session version) and rebuilds ksycoca before starting plasmashell.
Gate: 97/97 tests, clippy -D warnings (both feature sets), fmt, C-ABI harness PASS,
zero lumen references left outside .git.
