Summary

Records the completed Hub publication evidence for PR #291 without changing any implementation, generated catalog data, or recommendation disposition.

• Replaces the paper-review checklist's staged language with the actual merge, PR/exact-main workflow, artifact, deployment, live-byte, and stale-pin-boundary evidence.
• Cross-references the live central catalog publication from the encyclopedia roadmap.
• Appends the dated roadmap ledger row for the six paper recommendations plus the bundled A-D-12 and L-R-01 catalog publication.
