Factor the client-side skew handshake into a shared core helper (quic::clock_sync -> ClockSkew) so both the reference client and the embeddable connector use one implementation. NativeClient now runs the handshake at connect (right after Start, before the control task takes the stream) and stores the host-client offset; it's read over the C ABI via punktfunk_connection_clock_offset_ns (i64 ns, host minus client; 0 = no correction / old host). This is the substrate the Apple client needs for the decode->present (glass-to- glass) term: stamp present time, add the offset to express it in the host's capture clock, subtract the AU pts_ns. client-rs drops its local clock_sync copy and uses the shared helper (behavior unchanged; validated locally). Regenerates include/punktfunk_core.h. Roadmap section 12 + status updated. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

All three appliances advertise over mDNS (_punktfunk._udp) and require PIN pairing by default.
Progress log
2026-06-12
- Skew handshake in the connector + C ABI —
quic::clock_syncis now a shared core helper used by both the reference client andNativeClient; the connector runs it at connect and exposes the host clock offset over the C ABI (punktfunk_connection_clock_offset_ns). This is the substrate the Apple client needs for the decode→present (glass-to-glass) term. - Wall-clock skew handshake (
ClockProbe/ClockEcho, 8 NTP rounds afterStart) — makes the client's capture→reassembled latency valid cross-machine. Validated GNOME box → dev box: offset −1.57 ms removed, p50 1.30 ms skew-corrected. (05bc9ab) - Native LAN auto-discovery — host advertises
_punktfunk._udp(TXT: fingerprint, pairing, proto);punktfunk-client-rs --discoverlists hosts. Validated cross-LAN. (4fff464) - Third test box stood up — home-worker-3 (Ubuntu 26.04, RTX 4090, GNOME 50): first GNOME/Mutter
zero-copy streaming on a real desktop; 1 Gbps probe clean (625 MB/5 s,
send_dropped=0). Two physical-NVIDIA gotchas documented in GNOME Box Setup. - Encode|send thread split validated on real NIC (
send_dropped=0at 720p60 / 1080p120). (b295a5b)
Earlier (see roadmap + git log)
- 1 Gbps data plane: batched
sendmmsg/recvmmsg+ microburst-cap paced send thread. - Boot appliance: headless KDE session + host systemd units (no login).
- Speed test + settable bitrate: negotiation + bandwidth probe (host side).
- DualSense UHID + haptics; gamepads live; mic uplink; AV1 + surround (unit/live-capture tested).
In flight / next
See the Roadmap for the ordered list. Near-term:
- True glass-to-glass: Apple client present-stamp (decode→present) + host render→capture term.
- Apple stage-2 presenter (
VTDecompressionSession→CAMetalLayer). - Mandatory PIN pairing + delegated pairing approval; concurrent sessions.
- bazzite kept up to date (currently offline; one rebuild behind).
