  "description": "Default-off producer of the async external-job manifest (#1164). At execute:wave:post an executor can externalize long-running compute (SLURM first, scheduler-pluggable), commit a .planning/async-jobs/<job>.json manifest, defer SUMMARY.md, and return external_job_waiting. The core loop (#1165) consumes the manifest; this capability is the only thing that writes it. NOTE on contribution point: #1164 specifies classification at execute:wave:pre and recording at execute:wave:post. This capability still contributes executor guidance at wave:post; execute-phase now renders wave:pre entries and dispatches generic step hooks there independently. Moving external-job classification to wave:pre is a separate capability change, not part of #4148. The adapter (scripts/slurm-adapter.cjs) reads external_job.submit_timeout_ms / poll_timeout_ms / artifact_dir through the canonical capability-config seam (env override > config > registry default).",
