lib/nntp (XOVER client, Xref, GROUP), lib/headers (subjects, file keys, segments from overview lines; the yEnc path stays behind for phase 2), lib/release (identity, random names, now in lib), lib/files (aggregator, volume names), lib/rules (posting tools, owner by priority, release verdicts), lib/chunks (release chunk codec). Their unit tests came along; new ones for codec, rules and volumes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
