  "description": "A second `sm jobs submit` over the same `(extensionId, extensionVersion, nodeId, contentHash)` while the first is still queued MUST be refused with exit 3, naming the job that already covers the node. Deduplication is what stops a re-run from spending tokens recomputing an unchanged result (`job-lifecycle.md` §Duplicate prevention rationale), so the refusal is the contract, not an inconvenience.",
