The `wasapi` audio crate polls the default output device ~1×/s and
`log::debug!`s it (`wasapi::api default device Ok(...)`), flooding host.log
even at RUST_LOG=info: those `log`-crate records reach tracing through the
tracing-log bridge, and at *filter* time they carry the bridge's "log" shim
target, so neither a bare-info EnvFilter nor a `wasapi=warn` directive on the
file layer matches them (the ring already drops them post-hoc via
normalized_metadata + NOISY_DEBUG_TARGETS — the fmt layer filters pre-event and
can't).

Fix at the source: a shared `log_capture::install_global` replaces
SubscriberInitExt::init in both init paths (service file log + interactive
stderr) and inits the tracing-log bridge with `ignore_crate("wasapi")`, so the
poll records are dropped before they ever become tracing events — both sinks go
quiet, while every other log-crate dependency still reaches the console ring
(bridge max-level stays DEBUG). `wasapi` also added to NOISY_DEBUG_TARGETS as
belt-and-suspenders, and `log` moved dev-dep -> dep for LevelFilter.

Validated: .21 clippy (host --features nvenc) clean.

enricobuehlerandClaude Fable 5 600693914f fix(security): land the 2026-07 audit fixes — SSRF guards, roster lane, SYSTEM path hygiene
The low/medium findings from the July host+Windows security review, as
implemented in the audit session's working tree:

- Webhooks and library-art fetches refuse loopback/link-local/metadata
  targets and no longer follow redirects (SSRF pivots from the privileged
  host process).
- The paired-client rosters (/clients, /native/clients) move off the
  streaming-client auth lane — one paired device could enumerate every other
  device's name + fingerprint; only the bearer/loopback console keeps them.
- Device-name sanitizing extends to bidi/format control characters
  (spoofable rendering) via the shared native_pairing::is_spoofy_char;
  stream-marker quoting uses the same set.
- The SYSTEM service resolves powershell by its full System32 path —
  CreateProcess checks the launching EXE's own directory first, so a planted
  powershell.exe beside the host binary would have run as SYSTEM.
- The pf-vdisplay driver's opt-in file log moves from world-writable
  C:\Users\Public to WUDFHost's own temp dir.
- GameStream pairing sessions are single-use (removed whatever the outcome).
- Uninstall also removes the pf_mouse driver-store entry (rider from the
  virtual-HID-mouse work).
- openapi.json regenerated (hardened-config-dir doc wording).

enricobuehlerandClaude Opus 4.8 c42ce88921 refactor(host/W6.1): extract secret/config-dir helpers into the pf-paths leaf crate
Second de-coupling for the host crate carve (plan §W6.1 leaf). config_dir /
create_private_dir / write_secret_file (+ the Windows DACL helpers) were pub(crate) in the
gamestream junk drawer, yet consumed by vdisplay, stats, gpu, library, mgmt_token,
native_pairing and the Windows service — many of which become pf-media / pf-vdisplay, for
which crate::gamestream would be an illegal upward edge. New leaf crate pf-paths (pure std
+ tracing) owns them; ~40 call sites across 14 files repoint to pf_paths::. gamestream
keeps only its own concerns.

Verified: Linux (home-worker-5) clippy -p pf-paths -p punktfunk-host --all-targets
-D warnings + tests (347 pass, incl. secrets_are_written_owner_only); Windows
(192.168.1.158) clippy --features nvenc,amf-qsv --all-targets green.

enricobuehlerandClaude Fable 5 11045a0f70 chore: consolidate parallel-session WIP (HOLD — do not push)
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.

The mgmt REST API has bound 0.0.0.0:47990 by default since ae51276 so paired
clients can browse the game library over mTLS, but every packaged firewall
opener still excluded 47990 and the docs still claimed it was loopback-only.
On any host with an active firewall (ufw/firewalld) the LAN game-library
feature was silently broken.

Add 47990/tcp to the native firewall profiles (punktfunk.ufw [punktfunk-native]
+ punktfunk-native.xml) and correct the stale "loopback-only by default" text
across the debian/arch/bazzite READMEs and the docs site (incl. the factually
wrong --mgmt-bind default in host-cli.md, 127.0.0.1 -> 0.0.0.0). Opening the
port adds no admin exposure: off-loopback mgmt::require_auth serves only the
read-only status/library allowlist to a paired client cert; the bearer-token
admin surface stays loopback-only regardless of the bind.

Windows was already sound (shared parse_serve binds 0.0.0.0; service.rs already
firewall-opens 47990) — add a clarifying comment so the rule isn't mistaken for
accidental over-exposure.

enricobuehlerandClaude Fable 5 ea8e996989 fix(windows): IDD-push audit highs — keyed-mutex timeout, two per-frame leaks, IDD_PUSH knob, pooled-device threading
Five verified findings from the IDD-push/pf-vdisplay deep audit:

- Keyed-mutex acquire (BOTH endpoints): AcquireSync returns WAIT_TIMEOUT
  (0x102) / WAIT_ABANDONED (0x80) as SUCCESS-severity HRESULTs, which the
  windows-rs Result wrapper erases — a busy slot read as "acquired", so
  driver and host could race the same ring texture (torn frames) and the
  designed busy-skip backpressure was dead code. Both sides now classify
  the raw vtable HRESULT; WAIT_ABANDONED counts as acquired (ownership
  transfers — refusing it would wedge the slot forever).
- Host SDR hot path leaked one ID3D11VideoProcessorInputView per converted
  frame: the D3D11_VIDEO_PROCESSOR_STREAM ManuallyDrop field suppressed the
  release after VideoProcessorBlt. Released by hand now, success or not.
- Driver leaked IddCx's per-acquire surface reference (from_raw_borrowed on
  a TRANSFERRED reference — the MS sample Attach/Reset's it): the swap-chain
  surface set survived swap-chain destruction, the likely true root cause of
  the ~50 MB-per-reconnect VRAM loss that device pooling only mitigated.
  Now adopted via from_raw (publisher or not) and dropped pre-Finished.
- PUNKTFUNK_IDD_PUSH removed: capture is unconditionally IDD-push, but the
  vdisplay manager still gated the lingering-monitor preempt (and render
  pin) on the knob, whose default was OFF — dev/CLI runs reused a lingering
  monitor whose IddCx swap-chain is dead (black reconnect). The preempt and
  the render-GPU pin are now unconditional; host.env comments no longer
  promise the removed DDA/WGC fallback.
- Driver D3D device: dropped D3D11_CREATE_DEVICE_SINGLETHREADED (unsound
  since DEVICE_POOL shares one device across processors) and the pooled
  immediate context is now SetMultithreadProtected — two concurrent
  monitors' workers otherwise race an unlocked context (UB in the UMD).

No wire-contract change (pf-driver-proto untouched); the driver fixes take
effect on the next pf-vdisplay redeploy.

enricobuehlerandClaude Fable 5 796d381926 fix(windows): opt-in pad-driver file logs + size-capped service log rotation
Two disk-write fixes:

- pf-xusb/pf-dualsense no longer write C:\Users\Public\pf*-driver.log
  unconditionally — the file log is now opt-in (debug builds, or the
  PFXUSB_DEBUG_LOG / PFDS_DEBUG_LOG system env var), mirroring the audit-§4.4
  fix pf-vdisplay already got: a release driver never writes the world-writable
  Public file (info-leak/DoS surface), and the per-report OUTPUT/SET_STATE hex
  dumps stop being a sustained per-rumble disk-write path during gameplay.
  OutputDebugStringA stays unconditional; the host's driver-silence WARN and
  the gamepad-driver-health failure-mode table now say the log is opt-in.

- service.log/host.log get one-generation rotation: at each (re)open a file
  over 10 MB is renamed to .old, so a crash-restart loop or a RUST_LOG=debug
  left in host.env can't grow the append-forever logs without bound. Rotation
  runs only before an open (never under a live appender — host.log's handle
  lacks FILE_SHARE_DELETE, so a racing rename harmlessly fails).

Windows CI compile/clippy pending (drivers workspace + host are not
Linux-cross-checkable); rides along with the next pad-driver redeploy.

enricobuehlerandClaude Fable 5 82271d61dc feat(host/windows): "Punktfunk Host" identity in Task Manager (icon + version info)
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).

enricobuehlerandClaude Fable 5 ebada804b6 feat(tray): system-tray status icon for the host (Windows + Linux)
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).

enricobuehlerandClaude Fable 5 d86f1a6bdd feat(host,web): host log ring + GET /api/v1/logs + console Logs page
Remote debugging without shell access: a tracing layer tees every
event at DEBUG-and-up — independent of the RUST_LOG filter gating
stderr/host.log, so console-side debugging never needs a restart —
into a bounded in-memory ring (log_capture.rs, 4096 newest entries,
OnceLock singleton like config()), installed at both init sites
(stderr path in main, the Windows service file path). The mgmt API
serves it cursor-paged at GET /api/v1/logs?after=&limit= — bearer-only
and deliberately NOT on the mTLS cert allowlist (log lines can name
client identities and host paths). The web console grows a Logs page
(follow/pause · min-level filter · text search · eviction-gap badge);
polling self-paces: a non-empty page advances the after-cursor (new
query key → immediate refetch, drains backlogs), an empty page idles
at the 2s interval. OpenAPI regenerated; ring pagination/eviction,
layer wiring, and the authed route are unit-tested; Storybook story
included.

enricobuehlerandClaude Fable 5 6de4128298 feat(host/windows,packaging): installer overhaul - branding, VB-CABLE, GameStream choice, driver uninstall
- Modern branded wizard: WizardStyle=modern dynamic windows11 (Inno >= 6.6,
  plain-modern fallback for older compilers; CI provisioning upgrades a
  pre-6.6 Inno). Brand-mark wizard side panels + header tiles (100-200% DPI)
  and a multi-size punktfunk.ico (SetupIconFile + Apps & Features), generated
  AND committed by branding/gen-branding.ps1 from the canonical brand geometry.
  Gotcha encoded in the script: ISCC rejects all-PNG icons, so entries <= 64px
  are classic DIBs (PNG only at 128/256), and the ICO is load-verified.

- VB-CABLE actually ships now: windows-host.yml never set VBCABLE_DIR, so every
  published installer silently omitted the virtual mic (broken mic passthrough
  in the field). CI provisions the pinned, SHA-256-verified official Pack45
  (provision-windows-punktfunk-extras.ps1) and the pack now FAILS on a
  supplied-but-invalid dir instead of shipping mic-less again. Attribution per
  VB-Audio's bundling grant surfaced in the visible wizard task text (vendor,
  vb-cable.com, donationware) on top of the licenses notice.

- GameStream (Moonlight) compat is a wizard task (checked by default) ->
  service install --gamestream=on|off writes PUNKTFUNK_HOST_CMD=
  serve[ --gamestream] into host.env. Only the two canonical values are ever
  rewritten - a hand-customized command line survives upgrades. Silent
  installs: /MERGETASKS="!gamestream".

- Driver uninstall (field report: our virtual-device drivers survived
  uninstall): new `driver uninstall [--gamepad]` removes the pf-vdisplay
  device node(s) + the pf-vdisplay/pf-dualsense/pf-xusb driver-store packages,
  wired into [UninstallRun] after service uninstall. Locale-safe by
  construction: devices matched on unlocalized VALUES (never pnputil's
  localized labels), packages found by INF content scan - validated against a
  German-locale box ("Instanz-ID:" parse; 7/7 punktfunk INFs matched, no
  foreign hits). VB-CABLE is deliberately left installed (shared third-party
  component with its own uninstaller).

Installer compile, cargo check/clippy/fmt, and the ASCII locale gate are green;
the wizard look + uninstall flow still need one on-glass pass on a disposable
box (this box runs the live host).

enricobuehlerandClaude Sonnet 4.6 b9c8d5ab43 refactor(host/windows): collapse Windows capture to IDD-push only
Remove DXGI Desktop Duplication (DuplCapturer), Windows.Graphics.Capture
(WgcCapturer), the two-process SYSTEM+helper relay (virtual_stream_relay /
HelperRelay / DesktopWatcher / composed_flip), and the five source files that
implemented them. IDD direct-push is now the sole Windows capture path; the
session topology is always SingleProcess.

Deleted files: wgc.rs, wgc_relay.rs, desktop_watch.rs, composed_flip.rs,
windows/wgc_helper.rs (+ wgc-helper subcommand in main.rs).

dxgi.rs is kept but carved to shared GPU primitives only (make_device,
HdrP010Converter, VideoConverter, install_gpu_pref_hook, WinCaptureTarget,
pack_luid) — ~2237 lines of DDA-only code removed; imports cleaned.

capture.rs: IDD-push open failure fails the session cleanly (no fallback).
Adds capturer_supports_444() — returns false on Windows (IDD-push 4:4:4 is a
follow-up), replacing the stale single_process gate in 4:4:4 negotiation.
session_plan.rs: CaptureBackend{Dda,Wgc} and SessionTopology::TwoProcessRelay
removed. config.rs: no_helper/force_helper/no_wgc/capture_backend/secure_dda
removed. merged_env_block relocated from wgc_relay to windows/interactive.rs.

Linux cargo check clean.

enricobuehlerandClaude Opus 4.8 c1ce231dbf fix(host/security): Windows DACL hardening — close audit #2, #3, #8, #11
Windows local-privilege findings from design/security-review-2026-06-28.md.
These are #[cfg(windows)] paths (verify in CI / on the box; this Linux dev
VM can't compile MSVC). They follow the existing write_secret_file/icacls
patterns; the cross-platform parts are cargo check/clippy/test green.

- #2 [HIGH]: route the mgmt bearer token write through the shared
  write_secret_file so it gets the SAME Windows DACL (SYSTEM/Administrators)
  as the host key — it was cfg(unix)-only and left Users-readable, leaking
  full mgmt admin authority to any local user.
- #3 [HIGH]: create_private_dir now applies a restrictive DACL to the
  %ProgramData%\punktfunk config directory (re-owns to Administrators to
  defeat a pre-creation, strips inheritance, SYSTEM/Admins/OWNER full +
  Users read-only) so a local user can't plant host.env/apps.json that the
  SYSTEM service trusts (env/arg-injection LPE). host.env is now written
  DACL-locked via write_secret_file; the config + logs dirs go through
  create_private_dir.
- #8 [LOW]: write the web-console password file empty, icacls-lock it, THEN
  write the secret — closes the brief write-then-icacls TOCTOU window.
- #11 [LOW]: the SYSTEM logs dir is DACL-locked (Users read-only, no
  create), so a local user can't pre-plant host.log as a reparse/hardlink to
  redirect SYSTEM's writes (subsumed by the #3 dir lockdown).

Deferred: #5 (host<->UMDF gamepad/IDD shared-section Everyone:GENERIC_ALL).
The section SDDL is intentionally permissive because the UMDF driver opens
it under a restricted token of unknown SID/integrity; scoping it blind would
likely break the live-validated gamepad/IDD pipeline, so it needs on-box
validation first. Tracked in the report.

enricobuehlerandClaude Opus 4.8 79c8641c3f docs(host): prove unsafe blocks in the Windows + cross-platform files + gate them (unsafe-proof program 3/N)
Continues the unsafe-proof program across the Windows/cross-platform host files
(~75 blocks, 21 files), each with a SAFETY proof of the real invariant and a
per-file #![deny(clippy::undocumented_unsafe_blocks)] gate:

  capture/windows: dxgi.rs, wgc_relay.rs, wgc.rs, desktop_watch.rs, composed_flip.rs
                   (windows-rs COM: interface validity, same-D3D11-device textures,
                    immediate-context single-thread, borrowed args outlive the call)
  windows: service.rs (SCM/token/CreateProcessAsUserW/event handles — OwnedHandle
           liveness, no double-close/signal race), win_display, wgc_helper, interactive
  vdisplay/windows: manager.rs, pf_vdisplay.rs (SwDeviceCreate/IddCx/ioctl handle
                    liveness via the OnceLock VDM singleton + OwnedHandle)
  encode/windows: ffmpeg_win.rs (full AVBufferRef refcount audit — balanced, NO leaks,
                  unlike the vaapi sibling), sw.rs
  cross-platform: gamestream/audio.rs (libopus), gamestream/stream.rs (sendmmsg),
                  inject/windows/sendinput.rs, audio/windows/wasapi_mic.rs,
                  session_tuning.rs, vdisplay.rs

Two findings (handled separately):
- wgc_relay.rs `unsafe impl Sync for HelperRelay` is UNSOUND (its mpsc Receiver is
  !Sync) though not live-exploited — marked SUSPECT inline; fix pending box check
  (it touches the in-flight punktfunk1.rs).
- capture.rs / encode.rs (PARENT modules of the WIP idd_push.rs / nvenc.rs) do NOT
  get the file deny yet — it would propagate the lint into the undocumented WIP
  children. The deny lands there once those are documented (after the WIP commits).

Linux-visible parts verified green (cargo clippy -p punktfunk-host --all-targets
-- -D warnings). The cfg(windows) deny gates are box-verified next.

enricobuehlerandClaude Opus 4.8 f8c564b38f refactor(windows-host): OwnedHandle for the SCM STOP/SESSION events (Goal-3, last unsafe reduction)
The service's STOP/SESSION manual-reset events were smuggled across the C SCM
control-handler boundary as raw `isize` in `AtomicIsize` statics (the handler is a
capture-free `'static` closure, so it can't hold a non-`Send` `HANDLE` — it has to
reach the events through statics), reconstructed via `load_event`, and explicitly
`CloseHandle`d at `run_service` end.

Replace the raw-`isize` statics with `OnceLock<OwnedHandle>`:
- `run_service` creates each event, wraps it in an `OwnedHandle`, derives a borrowed
  `HANDLE` for `supervise` (unchanged signature), and `set`s the OnceLock (once per
  process) — all BEFORE the handler is registered, so the handler always sees `Some`.
- The handler reads `event_handle(&STOP_EVENT)` (a borrow) and `SetEvent`s it, with a
  defensive `None` guard (matches the old `SetEvent(HANDLE(0))` no-op if it ever fired
  pre-init).
- The events are owned by the OnceLocks for the process lifetime (the service process
  exits right after `run_service` returns, so the OS reaps them at exit). Dropping the
  explicit `CloseHandle` also removes the latent close-then-signal window the old
  statics had (the raw isize lingered after the close).

Deletes the `AtomicIsize`/`Ordering` import + `load_event` + the raw-isize smuggle —
the last host-side raw-handle reduction. Behaviour-preserving (same events, same
signal/wait/reset, same once-per-process init order). Linux check + fmt clean; the
file is #[cfg(windows)] → to be box-validated (compile + a service stop/restart).

enricobuehlerandClaude Opus 4.8 1d3b08bca6 fix(windows): clippy/build cleanups the on-glass build surfaced (-D warnings)
Built the host crate (`cargo clippy --features nvenc -D warnings`) and the driver
workspace (`cargo build`) on the RTX box — the project's intended Windows gate,
which `cargo check` (what the goal1/§2.5 work used) never runs. It surfaced lint
issues accumulated across the goal1 / §2.5 / this-session Windows work:

- 9× redundant `as *mut c_void` after `.as_raw_handle()` (already `*mut c_void`):
  idd_push.rs (3, this session), service.rs (3, this session), manager.rs (3,
  pre-existing §2.5 — my OwnedHandle work copied the idiom). Removed the casts +
  the now-unused `use std::ffi::c_void` in idd_push.rs / manager.rs (service still
  uses it).
- `if_same_then_else` in session_plan.rs::resolve_topology (pre-existing goal1
  stage 3): collapsed the two `false` arms into one condition (behavior identical).
- `unused_unsafe` in the driver `pod_init!` macro: it expands at call sites already
  inside an `unsafe` block, where its own `unsafe` is redundant — `#[allow(
  unused_unsafe)]` (needed at the non-unsafe sites, redundant at the nested ones).

After these, BOTH builds are clean on the box — validating the whole session's
blind Windows + driver work compiles + passes clippy on real hardware.

enricobuehlerandClaude Opus 4.8 62283098e7 refactor(windows-host): OwnedHandle for the service child + job handles (Goal-3 unsafe reduction #2)
The SCM supervisor scattered manual `CloseHandle(pi.hProcess)`/`(pi.hThread)`
across ~5 supervise-loop match arms and hand-closed the job object — easy to miss
an arm (leak) or double-close.

- `spawn_host` returns an owned `Child { process: OwnedHandle, _thread: OwnedHandle,
  pid }` instead of raw `PROCESS_INFORMATION`; the supervise loop borrows
  `child.process` (`HANDLE(as_raw_handle() as *mut c_void)`) for wait/Terminate and
  the `Child` auto-closes both handles when it drops / is replaced each iteration.
- The job object → `OwnedHandle` (borrowed for AssignProcessToJobObject), auto-closed.
- Deletes ~9 manual `CloseHandle` calls. The `_thread` handle is RAII-only (`_`-prefixed
  so `dead_code`/`-D warnings` doesn't flag it).

Deliberately LEFT the `STOP_EVENT`/`SESSION_EVENT` `AtomicIsize` statics as-is — they
are smuggled into the C SCM control handler, so `OwnedHandle`-ifying them is a separate,
riskier supervisor redesign out of scope here (noted in a comment).

Behavior preserved (the supervise state machine / wait semantics / restart-on-
session-change / kill-on-close are unchanged). Windows-only (CI-gated); adversarially
reviewed (no double-close, handles outlive their borrows, idiom matches manager.rs).

enricobuehlerandClaude Opus 4.8 02742955b4 feat(windows-host): IDD-push is the default capture path for fresh installs (P1)
Make the validated IDD-push zero-copy path the default for a fresh install,
without penalising dev / non-pf-driver runs:

- The shipped default config now enables it. Both seed sites set
  `PUNKTFUNK_VDISPLAY=pf` + `PUNKTFUNK_IDD_PUSH=1`: the hardcoded default the
  service writes on `service install` (`ensure_default_host_env`) AND the
  `host.env.example` template the installer bundles. A fresh install therefore
  runs the validated path (the installer also bundles the pf-vdisplay driver);
  it falls back to DDA if the driver can't attach.
- `idd_push` is now **value-aware** instead of a bare presence flag, so an
  operator can turn it OFF with `PUNKTFUNK_IDD_PUSH=0` in host.env — a `var_os`
  presence check read `=0` as "on". Unset still ⇒ off (the code default is
  unchanged, so existing host.env files and dev/CI runs are unaffected; only the
  shipped default config opts in).

Also scrubbed the stale "SudoVDA" wording in host.env.example. Linux cargo
clippy -p punktfunk-host -D warnings clean; the service.rs default string is
Windows-only (CI-gated).

enricobuehlerandClaude Opus 4.8 fced221684 refactor(windows-host): confine platform code under windows/ + linux/ folders (Goal-1 stage 6)
Move 36 platform-specific files into per-module `windows/` and `linux/` subfolders (and the
shared HID codecs into `inject/proto/`):
  capture/{windows,linux}/  encode/{windows,linux}/  inject/{windows,linux,proto}/
  audio/{windows,linux}/  vdisplay/{windows,linux}/
  src/windows/ (service, wgc_helper, win_adapter, win_display)
  src/linux/  (dmabuf_fence, drm_sync, zerocopy/)

Done with `#[path]`, NOT a module rename: every file moves into its folder while the
`crate::*::*` module names stay FLAT, so all caller paths and every internal `super::`/`crate::`
reference are unchanged — only the parent `mod` decls gained `#[path = "..."]`. This is the
codebase's existing pattern (inject's gamepad_windows) and makes the move byte-identical in
behaviour with ZERO reference churn, far lower risk than collapsing to a single
`crate::capture::windows::` namespace (that deeper rename is an optional follow-on; this delivers
the cfg-sprawl folder confinement the stage is about). Done LAST, after the semantic stages, so
the path churn didn't fight them.

Verified: Linux cargo check + clippy (-D warnings) clean; my mod-decl changes fmt-clean (the 3
remaining fmt diffs are pre-existing local-rustfmt-version skew that moved with their files); all
36 `#[path]` targets exist; no internal `#[path]`/`include!`/file-child-mod in any moved file
(the inline `mod X {` blocks are self-contained). Box build to follow.
