"""Only a full-dialogue embedded track satisfies a language.

Codex review 2026-09-16: has_target_language_stream checked language and codec
only, so an English "Signs & Songs" or forced ASS counted as full English
subtitles. With 1.14.3 that result also drops wanted rows (standalone scanner)
and hides "missing" in the episode list — a signs-only track would stop the
search for the dialogue subtitle.
