The Apple client grows full gamepad support and punktfunk/1 learns to negotiate
the virtual pad type:
- Protocol: Hello carries a GamepadPref byte (offset 21, the same trailing-byte
back-compat pattern as the compositor; echoed resolved in Welcome at 54).
Host precedence: explicit client choice > PUNKTFUNK_GAMEPAD env > Xbox 360,
DualSense (UHID) only where available. ABI: punktfunk_connect_ex2 +
punktfunk_connection_gamepad (connect_ex delegates; ABI_VERSION stays 2 — the
trailing byte IS the compat mechanism). punktfunk-client-rs gets --gamepad.
- Swift client: GamepadManager (app-lifetime discovery + selection — Settings
lists every controller with capabilities/battery/"In use"; exactly ONE pad
forwards as pad 0, auto = most recently connected, or pinned), GamepadCapture
(snapshot-diff button/axis events, DualSense touchpad + ~250 Hz motion on the
rich-input plane, held state released on switch/deactivate/stop),
GamepadFeedback (rumble → CoreHaptics per-handle engines; lightbar →
GCDeviceLight; player LEDs → playerIndex; adaptive-trigger blocks → the
table-driven DualSenseTriggerEffect parser → GCDualSenseAdaptiveTrigger,
exact for the 10-zone positional modes). The pad type auto-resolves from the
physical controller at connect time, user-overridable in Settings.
- Host DualSense fixes surfaced by adversarial review against hid-playstation /
SDL / Nielk1 ground truth: input-report sensor/touch offsets were off by one
(the kernel read garbage motion + phantom touches), the L2/R2 trigger blocks
were swapped (the report is right-trigger-first), feedback now gates on the
report's valid-flags (a plain rumble write no longer blanks lightbar/
triggers), and the touchpad rescale clamps to the advertised ABS_MT extents.
- Tests: Hello/Welcome trailing-byte back-compat, pick_gamepad precedence,
byte-exact input-report layout, valid-flag gating, per-mode trigger-parser
table (incl. packed 3-bit zones), wire conversions, and a scripted loopback
feedback burst (PUNKTFUNK_TEST_FEEDBACK=1) asserted through the xcframework
on the rumble + HID-output planes.
Validated: cargo test/clippy/fmt green on macOS + Linux (61 host tests), swift
build/test green, test-loopback.sh green, tvOS/iOS targets compile. DualSense
motion sign/scale is derived from the calibration blob, not yet live-verified
(constants isolated in GamepadWire).

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.
