A segment sourced from speaker_turns re-derived its speaker by greatest overlap. A turn's overlap with its own span is the largest possible, so a turn nested inside another speaker's turn could only tie with the container, and the tie went to whichever came first. sortformer_diar binarizes each speaker independently and sorts by start sample, so the container always comes first and the interjecting speaker was silently erased from DiarizeSegment.speaker. choose_segment_spans now carries the label out with the span. Also pins the nearest-segment fallback against measuring from either endpoint or from segment position, which a trailing-only stray word could not do, and exercises the empty-word guard in join_words. Two fixtures that pin a rule but do not mirror any pinned family are relabelled defensive. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io>

// Builds LocalAI's TranscriptResult shape from audio.cpp's TaskResult spans.

// THE RULE: the top-level transcript text is text_output verbatim, always.
|
|
// audio.cpp carries transcript text in exactly one place, TaskResult.text_output.
|
|
// speech_segments, speaker_turns and word_timestamps carry spans and labels but
|
|
// no text. Deriving the top-level text by concatenating per-segment text
|
|
// therefore yields an empty transcript for every producer that reports segments
|
|
// without word timestamps, which includes VibeVoice diarized ASR.
