The host half of the shared clipboard (design/clipboard-and-file-transfer.md §4),
ported from feat/shared-clipboard (6bd8c18b) into the post-W6 crate shape: the
backends land as a pf-clipboard subsystem crate (the pf-inject/pf-capture
pattern) instead of growing punktfunk-host back out, and the ~340-line
punktfunk1.rs integration is re-implemented against the native.rs/control.rs
split that replaced it.
pf-clipboard:
- host::wayland — ext-data-control-v1 (KWin / wlroots / Sway / Hyprland).
- host::mutter — GNOME via Mutter's *direct* org.gnome.Mutter.RemoteDesktop
clipboard (no data-control at any GNOME version; the xdg portal needs an
interactive grant a headless host can't answer).
- host::windows + host::winfmt — Win32 clipboard on a hidden message-loop
window: WM_CLIPBOARDUPDATE listener + OLE delayed rendering (WM_RENDERFORMAT)
for text / CF_HTML / RTF / PNG.
- host::session — the backend-agnostic coordinator bridging HostClipboard to
the QUIC clipboard plane (offers, fetch accept-loop, remote offers, pastes).
- A portable facade (policy / enabled / cap_advertised / ClipCoordCmd / start /
spawn_decline_loop) so the orchestrator compiles cfg-free on every platform;
ClipCoordCmd moves into the crate (it was host-owned before).
punktfunk-host glue:
- handshake.rs advertises HOST_CAP_CLIPBOARD via pf_clipboard::cap_advertised.
- serve_session starts the coordinator (gated on a real compositor — the
synthetic source stays out of the session clipboard) and spawns the
CLIP_FETCH_UNAVAILABLE decline loop when the policy is on but no backend bound.
- control.rs gains the ClipControl/ClipOffer arms + the host-offer forward
branch, and the e2e session test (cap advertise → ClipState ack with
BACKEND_UNAVAILABLE → fetch decline) rides in native.rs's tests.
Still opt-in default OFF (PUNKTFUNK_CLIPBOARD). Remaining: the macOS client
(design §5) — then this becomes user-visible.

Continue the W1 native-host restructure (plan §W1, steps 4+5). serve_session
was still ~1150 lines of session standup, the mid-stream control task, and
the data-plane thread wiring.
- native/control.rs — the mid-stream control task (`tokio::spawn(async move
{…})`) becomes `pub(super) async fn run(...)`: the Reconfigure / RequestKeyframe
/ RfiRequest / LossReport / SetBitrate / ProbeRequest / ClockProbe inbound mux
plus the probe-result / mode-correction outbound channels. Call site is now
`tokio::spawn(control::run(...))`.
- native/stream.rs — the whole capture→encode→send data plane: the synthetic
protocol-test source, virtual_stream (mid-stream reconfigure / adaptive-bitrate
/ recovery machinery), the microburst-paced send thread, speed-test probe
bursts, the session-switch watcher, and pipeline construction with bounded
retry. Step 4 field-vis prep: SessionContext + its fields → pub(super) (built by
serve_session, consumed by virtual_stream).
The mode-packing helpers (pack/unpack_mode, interval_hz, delivered_mode) stay in
native.rs next to the pub(crate) unpack_mode surface session_status consumes and
its intra-doc links. native.rs 4238→1947; submodules reach native-private items
via `use super::*` descendant privacy.
Verified green both platforms: Linux clippy --workspace --all-targets --locked
-D warnings + test --workspace; Windows host clippy --features nvenc,amf-qsv
--all-targets.
