`packaging/windows/drivers/*` has run `deny(unsafe_op_in_unsafe_fn)` +
`deny(clippy::undocumented_unsafe_blocks)` for a while, with `forbid(unsafe_code)`
on the modules that need no unsafe at all. The main workspace had no lint config
whatsoever, so nothing stopped a clean crate from quietly growing an `unsafe`, and
nothing distinguished the handful of genuinely-unsafe lines inside a 600-line
`unsafe fn` from the safe ones surrounding them.
Three things, all mechanical:
* `#![forbid(unsafe_code)]` on the eight crates that already contain zero unsafe
(`pf-driver-proto`, `pf-host-config`, `pf-paths`, the three clean clients, both
tools). These were clean by accident, not by contract; now they are clean by
contract.
* `unsafe_op_in_unsafe_fn = "warn"` workspace-wide. `unsafe fn` states a contract
the CALLER must uphold — it was never meant to switch off checking for the whole
body. Measured fallout is 300 sites on Linux, and they are concentrated: six
files carry all of them, while `punktfunk-core`, `pf-frame`, `pf-clipboard` and
`pf-vdisplay` are already at zero. `warn` (not `deny`) so the build stays green
while those six are worked down; it flips to `deny` once they are. This is also
the Rust 2024 default, so it pays off the edition migration early.
* `proc::current_uid()` replaces eight `unsafe { libc::getuid() }` blocks. Each
site had copied out the same SAFETY note verbatim, which is the tell: `getuid()`
is parameterless, always succeeds and touches no memory, so there is no contract
for a caller to uphold and no reason for the unsafe to be visible eight times.
One `unsafe` behind a safe wrapper, none at the call sites.
Verified: `pf-vdisplay` builds clean on Linux (Nobara) at zero E0133; the
macOS-buildable crates build clean locally. No behaviour change.
The tray led its tooltip with "⚠ conflicting host: Sunshine" and (on Linux)
went NeedsAttention for a Sunshine that was merely *installed* — never
started, never listening, harmless. An always-on warning over a dormant
package is a false alarm on every poll, and the tray is the wrong surface
for a one-shot install-time observation anyway.
Removes the `conflicts` field from the tray's `Summary`, the tooltip prefix,
`has_conflicts()`, and the ksni attention branch that fed on it. The host
still detects and reports conflicts where that belongs — the startup
`punktfunk::detect` warning, the `detect-conflicts` subcommand, and the
`/api/v1/local/summary` field, which the tray must (and does, per the new
test) keep tolerating on the wire.

The tray sat at "Idle" through an entire stream, and its Windows context menu
could come up without its main action. Two separate causes.
`GET /api/v1/local/summary` reported `video_streaming`/`audio_streaming` straight
from `AppState.streaming` — flags only the GameStream media pipeline raises. The
native punktfunk/1 plane is the DEFAULT (GameStream is opt-in) and never touches
them, so every native session read as idle: idle icon, and a tooltip that printed
that session's own resolution next to the word "idle" (the `session` field was
already native-aware). This is the blind spot `/status` was fixed for — see the
`session_status` module doc — which the summary kept. Both flags now OR in a live
native session, and the tray additionally treats a reported session as streaming,
so a new tray reads an older host correctly too.
The menu built "Open web console" (and the pairing entry) only while a live
loopback probe of the console had just succeeded. A console still starting, or an
SSR render slower than the 2 s probe timeout, therefore deleted the tray's
most-wanted action outright — indistinguishable from a tray that never had one,
with left-clicking the icon as the only, undiscoverable, way in. The entry is now
always present and the default item; a failed probe changes its label to
"(not responding)" instead of hiding it, and takes two consecutive misses to say
so, since one timeout is not "down".
While here: a "Release kept display…" entry when displays are held (the summary
field's own doc promised a one-click release that did not exist), and entries
deep-link to /pairing and /displays instead of all landing on the dashboard. The
Linux SNI menu mirrors all of it.

has_conflicts drives the Linux ksni backend's NeedsAttention state; the Windows
tray surfaces the same conflict through the tooltip headline() (it has no distinct
attention icon) and never calls the boolean, so `cargo clippy -p punktfunk-tray
-- -D warnings` failed dead-code on Windows (windows-host.yml). Scope the allow to
non-Linux rather than gate the shared API out.

Per plan §2.5: the security-critical rustls fingerprint-pinning ServerCertVerifier
was hand-rolled three times — quic/endpoint.rs (PinVerify), pf-client-core
library.rs, punktfunk-tray status.rs — drifting copies on a trust boundary. Add
one canonical punktfunk_core::tls::PinVerify (+ cert_fingerprint) behind a light
`tls` feature (rustls + sha2 only, no QUIC runtime); `quic` now depends on it, and
quic::endpoint re-exports cert_fingerprint so that path stays byte-stable
(gamestream + pf-client-core reach it there).
- core::tls::PinVerify: new(pin) for the HTTP clients, with_observed(pin, slot)
for the QUIC TOFU connect. Behavior-identical to all three originals (pin-check
+ real CertificateVerify signature verification; only hashes the leaf when a pin
or observed slot needs it). Two focused unit tests anchor the boundary.
- quic/endpoint.rs: drop the private PinVerify, wire client_pinned through
tls::PinVerify::with_observed.
- pf-client-core library.rs + tray status.rs: use the shared verifier; tray also
routes load_pin through core cert_fingerprint and drops its direct sha2 dep,
gaining only the light core `tls` feature (still no host dep, no QUIC runtime).
Verified on Linux (home-worker-5): clippy 0/0 for core(quic), core(tls),
pf-client-core, tray, host(nvenc,vulkan-encode,pyrowave); core 153 lib tests +
loopback 7/7 (pinned handshake) + c_abi round-trip green.

Local snapshot of intermingled in-flight work, committed to unblock the encode
refactor (a clean ffmpeg_win.rs for the vbv-dedup follow-on). These hunks span
the same files and can't be cleanly split here; the commit bundles three
distinct workstreams that each belong in their own PR:
- logging rework (~43 files: level re-tiering, structured fields, `?e`,
hot-path flood latches)
- conflicting-host detection (detect.rs + detect/{linux,windows}.rs + wiring
in main.rs/mgmt.rs/Cargo.toml/docs/packaging)
- standby-sink DWM-stall attribution (windows/display_events.rs + capture/
vdisplay wiring)
NOT verified as a combination. NOT to be pushed until the refactor is done and
these are re-verified and reorganized into their proper per-workstream PRs.

Session pump, FFmpeg decode, PipeWire audio, SDL3 gamepads, keymap, trust
store, mDNS discovery, library client and Wake-on-LAN move verbatim from
clients/linux into crates/pf-client-core, shared with the upcoming Vulkan
session binary (punktfunk-planning: linux-client-rearchitecture.md).
The GTK client re-exports them at the crate root so every existing
crate::-path keeps resolving; its manifest drops the moved-only deps.

Stage 8 polish. `GET /api/v1/local/summary` (the tray's loopback-only unauthenticated status
source) gains `kept_displays` — the count of lingering/pinned virtual displays (held with no live
session), over the already-validated `registry::snapshot()`. The tray shows it in the idle tooltip
("idle · 1 display kept"), so a user knows a display — and, under exclusive topology, their physical
monitors — is being held (e.g. a gaming-rig `forever` pin). Release stays via the console: a
state-changing release can't be an unauthenticated endpoint, and the non-elevated Windows tray
can't read the SYSTEM-DACL'd mgmt token, so a tray release button isn't cleanly cross-platform.
`#[serde(default)]` on the tray side keeps it compatible with an older host. Tray tests green.

punktfunk-host.exe embedded no icon or version resources, so Task Manager and
Explorer showed a bare lowercase exe name with a generic icon. build.rs now
embeds the branded .ico + FileDescription "Punktfunk Host" / ProductName
"Punktfunk" via winresource (same pattern as the Windows client and the tray;
Linux packaging builds skip the block). The tray gets a matching "Punktfunk
Tray" description, and the SCM display name moves off lowercase
"punktfunk streaming host" to "Punktfunk Host" (applied idempotently by
`service install` on upgrade).

The "Open web console" entry was gated on {exe dir}\web\web-run.cmd (Windows)
/ the punktfunk-web unit file (Linux) — which misses consoles run from a repo
checkout (the RTX box, caught on-glass) and shows a dead entry while an
installed console is stopped. The poller now probes https://127.0.0.1:<web
port>/ each cycle (any HTTP response = up, transport failure = down) and the
menu follows live on both platforms.

New crates/punktfunk-tray — a small per-user companion showing the host service
state at a glance (running / stopped / starting / degraded / failed + the live
session in the tooltip) with one-click actions: open web console, approve a
pending pairing request, start/stop/restart, open logs. No more digging through
logs to learn whether the service came back after a reboot or an update.
Status is service-manager-FIRST (SCM / systemd user unit — a port squatter can
never fake Running), then the new loopback-only unauthenticated
GET /api/v1/local/summary (counts/booleans only; the mgmt token and cert.pem
are SYSTEM/Admins-DACL'd on Windows, so a non-elevated tray cannot bearer-auth).
Windows: windows_subsystem binary (a console exe in the Run key would flash a
terminal at sign-in), Shell_NotifyIcon + hidden window, per-session single
instance, TaskbarCreated re-add, --quit for the uninstaller; service actions
elevate per click via ShellExecuteW "runas" onto the new
`punktfunk-host service restart` (stop → wait Stopped → start).
Linux: ksni/StatusNotifierItem over zbus, systemctl --user actions (no polkit),
/etc/xdg/autostart entry whose --autostart self-gates to actual host users.
Icons: scripts/gen-tray-icons.py (pure stdlib) renders the brand lens + status
dot into committed .ico/hicolor assets; deb/rpm/arch ship binary+autostart+icons.
Live-validated: Linux on the headless KDE session (SNI registration, state
transitions, menu-driven start, dbusmenu layout); Windows on the RTX box
(session-1 launch with no NIM_ADD failure, single instance, --quit, restart
round-trip, summary loopback-200/LAN-401).
