The payload floats group into clean x2 doubling chains (0.0079 0.016 0.032 ...
1.009) = a coefficient stored as its binary place values C*2^k across the
bit-planes, exactly how a bit-serial adder holds a number. Recovered base
coefficients correlate with the object's own screen-space edge/z slopes
(decode_corr.py, chain_decode.py), so igc_array.py's inputs are cross-validated
against the compiled stream. Fixed-point scales from FOOTER.SS (Czscale=2^20,
Ctexscale=2^16). Readout §02 + decode notes updated.
