Research-grounded sequence + per-goal approach/effort. Decisions: start with KDE startup
reliability; Bazzite via COPR RPM then bootc image; commit to full UHID DualSense.

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.

Five confirmed findings from a 46-agent review panel:
- Empty --mgmt-token no longer satisfies the non-loopback token gate
(critical: 'Bearer ' with an empty token authenticated; parse_serve now
bails on blank tokens and mgmt::run treats blank as none)
- axum's built-in body rejections (400/415/422) now wear the documented
ApiError envelope via an ApiJson extractor, and the spec documents them
- GET /health carries security([{}]) in the spec, matching the server's
auth exemption
- unpairClient's description no longer claims revocation the TLS layer
doesn't enforce yet (gamestream/tls.rs accepts any cert — known gap)
- CLAUDE.md/README.md no longer reference the deleted web.rs

A versioned control-plane REST API (/api/v1) on its own port (default
127.0.0.1:47990) serving host info, runtime status, paired-client
management, the pairing PIN flow, and session control (stop / force-IDR).
The OpenAPI 3.1 document is generated from the handlers by utoipa, served
live at /api/v1/openapi.json (+ Scalar docs at /api/docs), printable via
`lumen-host openapi`, and checked in at docs/api/openapi.json for client
codegen — a test fails if it drifts, mirroring the cbindgen header rule.
Auth: optional bearer token (--mgmt-token / LUMEN_MGMT_TOKEN), enforced on
everything but /health, and mandatory for non-loopback binds. PinGate
gains a waiter count so the API can report pin_pending; logs moved to
stderr so stdout stays machine-readable. Supersedes the web.rs stub.

Ubuntu 26.04 ships FFmpeg 8.0 (libavcodec 62); bump ffmpeg-next 7.1 -> 8.1 to bind it
as the intended pairing. No source changes needed — the encode API surface we use
(avcodec_send_frame, hwframe contexts, AV_PIX_FMT_CUDA, av_log) is stable across 7->8.
Workspace builds + all tests green; clippy/fmt clean. Refresh the 7.x doc references.

Prepares the move to the NVIDIA-GPU Ubuntu VM where M0/M2 run (macOS can't drive the
Wayland/GPU stack). The repo carries the context, since Claude Code sessions are
machine-local and don't transfer.
- CLAUDE.md: project state + design invariants + don't-regress security notes. Auto-loads
every session, so a fresh session on the VM continues from here.
- scripts/bootstrap-ubuntu.sh: verifies the (already-installed) NVIDIA/NVENC stack,
installs rustup + PipeWire/portal/wlroots/Sway + DRM/EGL/GBM/VA dev deps; GATES the
FFmpeg -dev headers so apt can't clobber a custom NVENC build; checks nvidia-drm.modeset.
- scripts/headless/: headless-Sway + xdg-desktop-portal-wlr config templates, the
NVIDIA-wlroots env workarounds, run-headless-sway.sh, and a wf-recorder->hevc_nvenc
capture smoke test (proves capture->NVENC with no Rust).
- docs/linux-setup.md: M0 walkthrough + verified gotchas (modeset, headless backend,
vGPU NVENC licensing, dmabuf->NVENC CPU-copy fallback, FFmpeg-dev gate, crate versions).
Ubuntu 24.04 package names/versions verified against the live archive; scripts pass
shellcheck and `bash -n`.
