First hardware run of --probe-decode, on the RTX 5070 Ti:
driver decode ops: H.264, H.265, AV1 (0xF)
Three names, four bits. 0xF is H.264|H.265|AV1|VP9 — bit 3 is
VK_VIDEO_CODEC_OPERATION_DECODE_VP9_BIT_KHR, a real decode operation this
client has no rung for, so the name table stopped short of it and the line
looked complete while silently dropping a codec the driver had advertised.
That is the exact failure this flag exists to prevent. The whole point of
--probe-decode is that a reader can trust the words to cover the number; a mask
with an unexplained bit asks them to trust it instead. VP9 is now named (marked
as having no punktfunk rung, because advertising it as decodable would be its
own lie), and any bit beyond the four we know prints as "unrecognised bits
0x…" rather than vanishing — so the next codec Khronos adds shows up as an
unknown rather than as nothing at all.
Gates: fmt clean; clippy -D warnings on punktfunk-client-session.
