0.6.0 (2026-07-14)

• Make clean owner-scoped so parallel sessions stop clobbering each other. The task registry (~/.codex-agents/tasks) is shared by every session on the machine, and clean --terminal/--all used to sweep it globally, deleting a sibling session's finished-but-uncollected results (and, with --all, its still-running tasks). This is backend-agnostic: codex, claude, and grok tasks all shared the one registry and the one sweep.
• Each task now records an owner at spawn (CDX_OWNER if set, else the resolved cwd, so separate worktrees isolate with zero config). clean --terminal/--all only remove tasks owned by the current session; owner is surfaced in status/list, and the JSON reports a skipped_foreign count.
• Add clean --any-owner to restore the global sweep as a deliberate opt-in (also the only way to reap pre-owner legacy tasks). kill/clean --task were already correctly single-target and are unchanged.
• clean now refuses to remove a still-running (or still-starting) task: clean --task on one errors with "kill it first", and --terminal/--all skip it (reported as skipped_running). Interrupting-then-deleting a live task raced the detached supervisor, which could resurrect the directory as a partial failed entry or orphan the backend, so clean only ever reaps terminal tasks now, the same rule send follows. Kill a task first (cdx kill) if you want it gone.
• Harden the detached supervisor against resurrecting a cleaned task: it finalizes state through a new non-creating write, so if clean removed the directory in the meantime the write fails cleanly instead of re-creating a stale task. Read paths (status/list/result) that opportunistically persist derived state no longer resurrect a cleaned task either. clean re-checks each task is still terminal immediately before removing it, retries the removal when the supervisor's one-shot finalize write races the rmtree (so the directory is never left half-removed), reports that rare still-finalizing case as skipped_finalizing with "re-run clean" guidance rather than mislabeling it as a running task, and surfaces a genuine rmtree failure (permissions, I/O) instead of swallowing it.
• SKILL.md: replace the blanket "clean --terminal once results are harvested" housekeeping advice with the owner-scoping contract and the CDX_OWNER override.
