enricobuehler 5c05246098 feat: M10 — FFmpeg is gone from the client
cargo tree -p punktfunk-client-session finds no ffmpeg. The host still does,
which is the whole point: pf-encode keeps libavcodec unconditionally and no
host workflow, packaging script or licence file was touched.

Deleted: crates/pf-ffvk, video_vulkan.rs, video_vaapi.rs, video_libav.rs, the
libavcodec half of video_d3d11.rs, the av_log machinery, ffmpeg::codec::Id as
the decoder's vocabulary (the quic CODEC_* wire constants now serve, which is
why the evidence table was keyed on them), DecodedImage::VkFrame and ::Dmabuf,
the presenter's AVVkFrame lane, and the ffmpeg-fallback feature with
everything behind it. DrmFrameGuard collapses from an enum to a newtype, which
removes an unsafe impl Send. Roughly 25,000 lines.

Then the CI, packaging, licensing and docs work the plan's §6 lists: the
Windows workflows lose FFMPEG_DIR, PF_FFVK_VULKAN_INCLUDE and their PATH
prepend; the MSIX loses its DLL wildcard; the client .deb stops emitting libav
sonames on its own because depends come from dpkg-shlibdeps; arch, flatpak and
nix drop the dependency; and the README's "FFmpeg 7 or 8" contract narrows to
the host.

Three defects reached users' machines in the first cut, and none was in the
deletion itself.

All three desktop Settings UIs offer vulkan, vaapi and d3d11va as stored
decoder values, so those strings sit in shipped settings files today. Refusing
them by name — which is the correct rule for a stale pin — would have bricked
every upgraded client whose owner ever touched that dropdown. They now migrate
onto the native rung for the same hardware family, at decoder construction AND
at each dialog's lookup, because a legacy value that matches no preset
displays as "Automatic" and silently rewrites the user's preference on the
next save.

M9's evidence filter was deleted on the argument that with no libavcodec twin
below, barring an unproven rung removes hardware decode rather than moving
down one rung. That is true on Windows and false on Linux for Intel and every
unknown vendor id, where prefer_vulkan_first is false and the order is
native-vaapi → native-vk: a rung that has decoded nothing anywhere sitting
above one that is 250/250 on three drivers. Every Intel Linux desktop would
have moved from libavcodec VAAPI, shipping for years, onto pf-vaadec by
default — and a rung that constructs and then produces wrong pixels leaves
only by the error-streak demotion, which this codebase already documents as
not tripping on the B580's strobing. The filter is restored as a narrow, pure,
testable rule: an unproven rung yields to a proven one, and to nothing else.
Windows deliberately passes no rung below, because that vendor family is the
one with a measured wrong-pixel report against Vulkan decode, and trading no
evidence for evidence of corruption is the wrong direction.

And the notices still said FFmpeg was bundled. The root file is what both
desktop clients include_str! and what the MSIX ships, three lines under the
new card saying no FFmpeg is bundled; Apple's Acknowledgements said it too, on
iOS, tvOS and macOS. The generator now emits four per-client files scoped by
transitive closure — 0 FFmpeg mentions in each, verified — while the root file
keeps it for the host. That also ends the standing false attribution of
ffmpeg-next, GTK4, windows-rs and the NVENC SDK to an iPhone.

Windows has no reachable box, so it was compiled instead: a cross clippy at
-D warnings on x86_64 and aarch64-pc-windows-msvc with the C toolchain stubbed
so build scripts run without linking. That gate immediately caught an
include_str! path one directory too deep, which nothing else could have.

Gates: container clippy -D warnings, 160 tests, workspace check, both Windows
targets clean, client ffmpeg count 0 and host 2. The four decode crates are
untouched, so the hardware rungs' 250/250 stands.

⚠ Owed and unrun: no GPU has executed any of this milestone. M8's on-glass
software check, M7's D3D11 and VAAPI AV1 hardware legs, and M9's field bake
all still want hardware, and the bake window and criteria remain the user's.

# The `unsafe` discipline the `packaging/windows/drivers/*` crates already run, extended to the
# workspace. `unsafe fn` marks a CONTRACT the caller must uphold; it is not a licence for the whole
# body to skip checking. Without this lint an `unsafe fn` body is unchecked end to end, so a 600-line
# function hides which handful of lines are actually the unsafe ones — exactly the reviewer-hostile
# shape we are working down. (This is the Rust 2024 default; adopting it early also pays off the
# edition migration.)
#
# `deny`, not `warn`. `warn` was never actually a softer setting: CI runs `cargo clippy … -D
# warnings`, which promotes it to a hard error anyway — that is how adopting this lint turned main
# red on every platform for a day without the level in this file ever saying `deny`. A level that
# lies about its own severity is worse than a strict one, so this now states what CI already does,
# and the exemptions are written down per file instead of hiding in a 689-warning wall nobody reads.
#
# THE EXEMPTIONS. Fourteen GPU/FFI backend files carry `#![allow(unsafe_op_in_unsafe_fn)]` with a
# one-line reason each. They are not "not done yet" — they are where this lint stops paying:
# their bodies are ash/CUDA/AMF/libav calls almost line for line (measured: 64% of the sites are a
# single third-party FFI call, and of the 44 `unsafe fn`s in them only 4 have a body containing no
# unsafe operation at all). Narrowing them means one `unsafe {}` per line plus, since pf-encode also
# denies `clippy::undocumented_unsafe_blocks`, one hand-written SAFETY comment per line that could
# only ever restate "an ash call on a live device" — the precise noise that made `unsafe` stop
# meaning anything here before (see the header of `pf-win-display/src/win_display.rs`).
#
# Everything else in the workspace is at zero and enforced. Removing one of those allows, file by
# file, is real work with a real payoff; blanket-narrowing all fourteen is not. Prefer DELETING an
# `unsafe fn` marker over wrapping its body: keep the marker only where a caller can actually break
# something (a raw pointer, a borrowed HANDLE, a GPU object that must not be in flight).
