Authoritative optimized-server comparison: optimization-c64/ and optimization-c256/.
Combined report: optimization-report.txt. The 96 runs include original Skirr,
optimized Skirr, Weft and Peregrine. Source and binary hashes match the delivered
code and wheel. The original binary/source are archived in ../profiles/before-source.tar.gz.

Earlier prototype comparisons remain in final-c64/, final-c256/ and report.txt.
Other baseline/prototype/review/optN folders are diagnostic engineering history,
not pooled into the authoritative comparison. opt9 used the previous optimized
build as its baseline and was rejected for lack of latency improvement.
