docs: record BWT params 14/15 + the LZ window feed fix (296ee88) Biggest real-corpus jump so far: -co 43->52, -cO 45->54 on one identical 60-file corpus. Documents the recurring "block bypasses the decoder, shared state stops advancing" bug shape. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
docs: record the decr_param==2 audio port (a2c6861) AudioPred ported; -cO byte-exact across formats and multi-block. Documents the two distinct NanoZip audio bitstream families and why -co/-cc still decline (reference itself diverges, port is bit-identical to it).

docs: record the -co/-cO BWT port (58c11b2 + 6b30a43) Both decr_param==0 shapes now decode natively: raw-stored BWT output and the 256-bucket MTF/arithmetic entropy layer. Includes the -O2 UB loop-bound bug inherited from the reference decoder and how it was found. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
docs: record the CM cross-chunk continuation fix (-cc, 25d2f75) Corrects the earlier "param2 bug, not yet root-caused" note: the actual bug was the CM model losing sync across a stored block sitting between two decr_param==0 CM chunks, not NzBwtRleDecodeU32 itself.

Update wiki for -co/-cO single-container chain-mode support Marks chain mode (multiple stream_tag segments) as done for both -co and -cO, adds a changelog entry. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Move detailed component status, RE notes, and changelog out of README Splits the previously-monolithic README into: this wiki (per-codec detail, reverse-engineering methodology/findings, full day-by-day changelog) and a short README (overview, measured summary table, build/test, license) that links here for detail.
