yap^330 The host reports the dictation key and every other key

What it says

The host reports the dictation key going down and up, once each per press, with its monotonic clock in milliseconds, and reports every other key that goes down while the dictation key is held, before the dictation key's release. Key repeats are not reported as presses.

Evidence

assumed	Stated, not proved. The proofs rely on it.
fuzzed	Not shown yet: the claim-driven fuzzer held it in every random sequence (docs/fuzz.md). A CI step will publish it (#95).
