The file moves (docs/ → design/, docs/api/openapi.json → api/openapi.json) landed
in d01a8fd, but the matching reference updates did not — so mgmt.rs's drift-test
`include_str!("../../../docs/api/openapi.json")` pointed at a path that no longer
exists and the host failed to build. This restores it and updates every reference:
- mgmt.rs include_str! → ../../../api/openapi.json (fixes the build)
- web/orval.config.ts codegen target, web/Dockerfile, .dockerignore
- deb/rpm/Arch packaging install paths
- CLAUDE.md, the .gitea CI workflows, code doc-comments, design-doc cross-links
docs-site route URLs (/docs/...) untouched.

# Build a punktfunk-host .deb for Ubuntu/Debian hosts.
|
|
#
|
|
# Mirrors the Fedora RPM (../rpm/punktfunk.spec): the host binary + the uinput udev rule
|
|
# + the systemd *user* unit + headless session helpers + example config + the OpenAPI doc.
|
|
#
|
|
# Runtime Depends are computed by `dpkg-shlibdeps` from the binary's actual DT_NEEDED, NOT
|
|
# hand-listed: the binary pulls a large transitive lib closure (most of it via ffmpeg) and
|
|
# the exact soname package names (libavcodec62, libpipewire-0.3-0t64, …) drift across distro
|
|
# releases — shlibdeps tracks them automatically and pins them to whatever the BUILD distro
|
|
# ships. Build this inside the Ubuntu 26.04 rust-ci image so those names match the target
|
|
# boxes exactly. `--ignore-missing-info` drops libcuda.so.1 (the NVIDIA driver lib, linked via
|
|
# FFI): on a GPU-less builder it resolves to no package, and we must never hard-depend on a
|
|
# specific libnvidia-compute-<ver> anyway — NVENC/EGL come from the driver, out of band.
|
|
#
|
|
# Usage: VERSION=0.0.1~ci42.gdeadbee [ARCH=amd64] bash packaging/debian/build-deb.sh
|

Description: Low-latency desktop/game streaming host (Moonlight + punktfunk/1)
|
|
punktfunk is a Linux-first, low-latency desktop and game streaming host. It speaks
|
|
the Moonlight/GameStream protocol (pair a stock Moonlight client) and its own native
|
|
punktfunk/1 protocol (GF(2^16) Leopard FEC + AES-GCM, mid-stream mode renegotiation,
|
|
client microphone passthrough). Each session gets a virtual output at the client's
|
|
exact resolution and refresh via a per-compositor backend (KWin, gamescope, Mutter,
|
|
Sway/wlroots), captured zero-copy (dmabuf -> CUDA -> NVENC). Input (mouse, keyboard,
|
|
gamepads) is injected back into the session.
|
|
.
|
|
NVENC + GPU EGL come from the NVIDIA driver (libnvidia-encode / libEGL_nvidia),
|
|
installed out of band. After install: add yourself to the 'input' group for virtual
|
|
gamepads, then enable the systemd user service punktfunk-host.
