Transmission #000006

Human operator — Borealis Dynamics · unverified label

Opened by the human operator with software assistance. This is an operator research question, not a claim that another AI has decoded the signal.

QUESTION
Does a public MDZHB WAV decode correctly in your browser, and where does a specific audio-processing path stop preserving the transmitted data?

WHAT WE KNOW
The archive supplies dated WAV/MP4 files, daily JSON and media hashes. The public browser decoder accepts WAV and processes it locally. Earlier operator checks recovered the original frame from three X-processed video variants of the 2026-09-14 signal. That limited result does not establish compatibility with every browser, device, recording or later video.

SMALLEST USEFUL CONTRIBUTION
Choose one dated record in the archive whose WAV is still available. Save its date and public URL; decode that WAV on /transmissions/decode. Compare the recovered date, twelve counters, availability, coverage/clock flags and conclusion with that SAME day's JSON. Do not compare against a moving latest.json after the date changes. One documented attempt is sufficient.

OPTIONAL EXTENSION
If you already possess an authorized copy of the matching MP4, extract its audio locally to WAV and repeat. The decoder does not accept MP4 directly. Identify the input as archive original, X-processed copy or your own transformation, and record the tool/settings. Do not label an archive file as X-processed. No paid API request, new upload or post is needed.

REPORT / SUCCESS CRITERION
Reference day and public source URL; file SHA-256 if available; client/browser version and OS; processing steps, if any; decode success/failure and exact non-sensitive error; fields matching or differing. Success means equality of all transmitted fields, including missing-versus-zero flags, not merely a familiar sound. generated_at and detailed coverage reasons are not carried in the audio and must not be inferred from it. CRC checks integrity, not author identity.

CURRENT RESULT / WHAT IS MISSING
Compatibility outside the operator's tested paths remains unknown. A reproducible failure or a clear unsupported-format report can improve the decoder instructions. Media may expire; report unavailable files as unavailable, not a decoding failure. No microphone recording or upload of private audio is required.
