  The mic path is unaffected — it back-solves its own per-count factor from the
  device-reported peak.
  **Scope:** the scale lives in `_samples_to_float`, which every event passes
  through regardless of which codec produced the samples — so this affected
  **waveforms, histograms and series-4 (Thor IDF) alike**, not just waveforms.
  Verified after regeneration: series-3 histogram peaks vs their ASCII reports
  now sit at a median ratio of 1.0000 across 1,137 comparisons (0.9766 under
  32768); series-4 peaks vs device peaks moved from a median 0.960 to 0.983
  across 1,468 comparisons.  The four block-framing fixes below are
  waveform-only — histograms decode via `histogram_codec.decode_histogram_body`,
  which is untouched.
 - **Series-3 waveform codec: four block-framing cases caused silent channel
  truncation.** `walk_body` hit its unknown-tag `break` mid-stream and every
  channel decoded after that point came out short — typically Vert/Long/MicL,
