video metadata --remove now blanks app-export JSON in keyed and keyless
metadata items (Dreamina writes it twice), which it previously left in
place while exiting 1.
Kling writes an H.264 user_data_unregistered SEI message (a fixed UUID
plus "kling-ai") into the first video sample. get_ai_metadata reports
it as kling_sei, identify_video names Kling from it when no TC260 label
does, and the streaming stripper blanks every copy inside mdat during
its existing copy pass. Lengths stay, the SEI stays well-formed, and
ffmpeg framemd5 hashes of every frame match before and after on both
tracked Kling fixtures. Across 255 local files only the seven Kling
videos changed verdict.
invisible now exits 1 on an undecodable source instead of reporting the
no-signal code for a file it never read.
Docs: a per-command "what each path leaves behind" table, the October
literature sweep, Suno's announced audio watermark, Anthropic's
SynthID-Text-based Claude watermark, and an independent TrustMark
false-positive benchmark.
