Two body-model rewrites, a systematic scale error affecting every
geophone reading the system ever produced, a recovered file format, and
two artifact-hygiene bugs where stale files outlived the decodes that
made them.
- geo full scale is 32000 ADC counts, not 32768 (every reading 2.34% low)
- the waveform body is a record chain, not a tag stream
- the histogram block is big-endian, with a terminal tail
- sub-minute intervals pack several per block (415 files recovered)
- three more defects found by a full-corpus sweep, each masking the next
- stale .h5 files and stale shape_* columns are now cleared, not left
All 11,603 series-3 binaries in the production snapshot pass every check.
Ground truth: 1,211/1,211 histograms exact per-interval, 75/75 waveform
sample counts exact, multi-interval fixture exact on all 45,680 values.
Also corrects a changelog note that went stale within the same day: the
"3 of 75 events still truncate" item was resolved by the record-chain
rewrite, and the remaining open items are now listed explicitly.
CLAUDE.md gains a "Where things stand" block at the top — the header had
been reading v0.21.0, four releases behind, which is the first thing you
see when picking the project back up.
Tests: 259 passed; the 16 failures are pre-existing (gitignored
fixtures) and unchanged from baseline.
