`proc://`: jobs, agents, and services; `proc://<id>` status/output; write sends stdin to services only (empty = Enter); `proc://<id>/kill` cancels/stops jobs, agents, and services, omit `content`; `proc://<id>/mode`: `persist`|`session`|`detached` (services only); start long-lived work as a named service when it needs stdin or lifetime controls; `proc://<id>/streams` lists a bash job's pipes, `proc://<id>/streams/<n>` reads what crossed pipe `n` so far (live under `| tail`/`| grep`; never rerun to see it); completed jobs evicted (process-local); parked agents/missing job ≠ lost: check `agent://<id>`, `history://<id>`.
