Session worktree branches (session-<id>) never get an upstream, so the original atRisk rule (unpushed !== 0) flagged every worktree-backed session as at-risk on delete — even pristine ones — forcing a Stash/Force confirm on each. Gate the unpushed arm behind hasUpstream (unpushed !== -1) so the no-upstream sentinel can't trigger it: atRisk = dirty || unmerged > 0 || (hasUpstream && unpushed > 0). No protection is lost — any genuinely unsafe local commit also shows as unmerged > 0 — and the unpushed > 0 arm stays correct for P1.5's pushable worktree branches. unpushed is still reported (-1 = local-only) as informational. Follow-up to 3a26563.
