The reviewer noted the in-order emitter's else branch (a NOT-next-to-emit
segment failing → buffer an empty placeholder so the drain can skip it,
use-streaming-dictation.ts:215-218) was the one reachable ordering branch
left uncovered. Add a non-vacuous case: with 3 segments, reject seq 1
(out of order) → one notification, nothing emitted; resolve seq 0 → "alpha";
resolve seq 2 → "gamma". The seq-2 flush proves the empty placeholder let the
emitter advance PAST the failed seq 1 — without the else branch the drain
would stall at the missing seq 1 and "gamma" would never emit.
