Three "truth layers" had drifted apart between commits. Fixed:
1. waveform_codec.py docstring rewritten from the 2026-05-08
"structural framing only" state to the 2026-05-11 "Tran segment 0
solved + segment-header partially decoded" state. Killed stale
"~80 sample-sets per segment" language (real segments are
flash-page-byte-sized, not sample-count-sized; observed first-segment
sizes are 42-510 samples depending on signal). Killed stale
"preamble is 7 or 9 bytes" language (always 7).
2. docs/instantel_protocol_reference.md §7.6.1: added a clear
"CURRENT STATUS" box at the top with a status table. Replaced the
stale "~80 sample-sets" line with the verified per-event segment
sizes. Merged two redundant segment-header field-table sections.
3. docs/waveform_codec_re_status.md (NEW): clean working-status doc.
Solved / not solved / hypothesis / next experiment / fixtures /
tests. The protocol reference remains the historical Rosetta
Stone; this new file is the current-truth working note that
shouldn't accumulate fossil layers.
4. CLAUDE.md §"Waveform body codec": prominent warning box at top —
"DO NOT TRUST decoded sample arrays yet." BW binary passthrough
is the only sample-bearing output to trust until the decoder
lands. Added a "Next experiment" subsection pointing the next
pass at the segment-channel scoring analyzer.
40 tests still pass.
