A synchronous systemctl try-restart of the portal chain (xdg-desktop-portal is Type=dbus,
waits for its bus name) blocked the script ~30-40s before plasmashell started. --no-block
queues the restart and returns immediately — the portal only needs to be ready before the
first client streams (seconds later), not before plasmashell. Validated: plasmashell up in
1s (was ~30s); a virtual capture session against the fresh session streamed 720/720 frames
@720p120, zero-copy CUDA, no black screen.

Headless KDE startup was a chain of timing-sensitive handoffs gated by a blind `sleep 2`,
the dominant source of black screens. Phase-1 fixes:
- New `punktfunk-host probe-compositor` subcommand: exits 0 iff the detected compositor is
up AND ready to create a virtual output now. KWin gets a real check (connect + registry
roundtrip + the privileged zkde_screencast global must be advertised — what the backend
needs); gamescope/Mutter/wlroots create on demand so the probe just confirms Linux.
(vdisplay::probe dispatcher + kwin::probe; reuses kwin.rs's existing roundtrip path.)
- run-headless-kde.sh: replace `sleep 2` with an active readiness wait (poll probe-compositor
until ready, 30s deadline, and bail with kwin's log if kwin_wayland exits during init).
Move the portal restart to AFTER readiness, and precede it with `systemctl --user
import-environment` + `dbus-update-activation-environment` (the missing env import — the
Sway script does this; without it a restarted portal inherits a stale/empty WAYLAND_DISPLAY,
which is the "streams but eats no input/audio" failure). kwin's stderr → a log file.
Validated: probe-compositor exits 0 "Kwin ready" against the live session, exit 1 with a
clear diagnostic when the compositor is absent. 114 tests green, clippy/fmt clean.

The portal processes bind to the compositor that existed when they started; after a kwin
restart the stale instances point at a dead socket and RemoteDesktop/EIS input injection
times out ("EIS setup timed out"). Hit live: a fresh session streamed fine but ate no
mouse/keyboard until the portals were restarted.

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.
