pf-presenter's 120 sites are `ash` calls almost without exception, so 120 independent arguments
would have been 120 restatements of the signature — the exact noise this program exists to remove.
They get the `abi.rs` treatment instead: the Vulkan contract stated once in `lib.rs`, each site
naming which of three shapes it is.
The three are not equal, and separating them is the point. CREATE and RECORD carry no real
precondition — the device is owned, the builders are locals, nothing executes until submit. DESTROY
does: the GPU must not still be using the object, and that is established by the path (a fence wait,
a `queue_wait_idle`, a retired swapchain), not by the call. Those sites say so, because getting it
wrong is a use-after-free no type catches. The contract also tells the next person that a block
outside the three shapes needs a real proof, and that writing "as above" is the signal it doesn't
belong in them.
punktfunk-core's Windows half is finished here too: `qos_windows.rs`'s `GetLastError` reads (called
before anything can reset the thread's error slot) and `udp/windows.rs`'s control-message write,
whose argument is that `ctrl` is sized by `WSA_CMSG_SPACE(4)` — computed two lines up — so header
plus payload cannot run past it, and `write_unaligned` is used because `WSA_CMSG_DATA` offers no
alignment guarantee.
⚠️ THE WINDOWS BLIND SPOT BIT A THIRD TIME. A Linux measurement put this crate pair at 113; the
real number was 129 — `d3d11.rs`, `win32.rs`, `qos_windows.rs`, `udp/windows.rs` are all
`cfg`-hidden. Every crate in this sweep had to be finished on .47 after being "done" on .21. For a
cross-platform crate the Linux number is a lower bound, never the answer.
All three crates now deny `undocumented_unsafe_blocks`, which was the goal: it applied to 8 of 11
crates carrying unsafe, and the three exempt ones held 381 items between them — including the C ABI
surface and the presenter. Verified: Linux .21 fmt + both CI clippy steps rc=0; Windows .47 all four
closed crates clippy `-D warnings` rc=0 plus the full Windows CI clippy set and pf-capture's tests.
Only small crates remain unguarded (75 items total, largest 26).
