Pattern: cancellation is becoming a first-class correctness feature across agent CLIs
Cline Desktop 0.0.21 made Stop propagate to delegated subagents and teammates and persist cancelled teammate tasks as cancelled; Claude Code 2.1.251 fixed a self-hosted runner leaving Bash processes alive after a force-stop and background subagents unable to reply to a sibling; Codex 0.152.0 spent multiple PRs on Guardian review context rollover and turn token budgets across delegated reviews. Three independent CLIs shipped orphaned-work fixes inside four days. The underlying cause is that fan-out shipped before lifecycle management did, and the bill arrives as background agents still burning quota after the user thought they stopped.
