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.

GCKeyboard reads the HID state directly, so the key NSEvents kept traveling the
responder chain unhandled — and an unhandled keyDown makes NSWindow play the
"invalid input" sound on every keystroke. InputCapture now installs a local event
monitor for its lifetime that swallows key events, except ⌘-combos, which still
reach the local app (the HUD's ⌘D disconnect, ⌘Q) in addition to the host.

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.
