`closeHeadlessMobileTerminalTab` minted `headless:<now>` on every close. Its sibling headless writers carry the stored `publicationEpoch` forward and mint only when there is no snapshot to inherit from — because a write to a worktree is not a claim to publish it. The close was the one writer that claimed. A paired client retires the epoch a new publisher displaces, and the web mirror's retirement is final: there is no revive lane, and the per-worktree tracking teardown deliberately keeps the epoch history. So an ordinary close published a stranger for a worktree the renderer generation still owned, retired that generation on every client, and the renderer's next publication — carrying the epoch the close had just retired — was rejected forever. The user emptied a workspace, created a terminal, and it never arrived on either machine while `session.tabs.list` showed the host holding it. This is the same thesis the retraction path already states, through the door next to it: a retraction is not a handover, and neither is a close. Measured on `paired-two-client-emptied-workspace-reseed.spec.ts`, six runs each: phase 2 failed 3/6 before (`A=null B=null`, both clients blind for the full 30s budget) and 0/6 after, with both clients adopting in single-digit milliseconds.
