[lidge-jun]

Summary

Adds the closeout verification block to the landing record merged in #3243: the four squash commits proven as ancestors of the landed dev, and the landed tree verified green for every surface the Cursor identity work touched.

bun test (11 files: cursor-*, fastwire-policy, claude-*, codex-catalog,
          agent-task-recovery)                                              662 pass / 0 fail
