Use when one issue or PR is too large for a worker and partitions into disjoint write sets. Not for independent parallel tasks: use parallel-launch. No remote or irreversible changes.

# Diamond task

## Contract

| Field | Bound contract |
|---|---|
| Trigger | Use when one issue or pull request is too large or too entangled for one worker and its complete writable surface can be partitioned into disjoint write sets. |
| Authority | Reversible local: writes only the named local run artifacts and declared target write sets; rollback is restoring the pre-run checkpoint. No remote mutation. This is the sole production task-DAG generator. |
| Side effect | Run isolated workers and apply their returned diffs by mechanical union within their declared write sets; the composer authors no content and changes nothing outside those sets. |
| Done | Produce one result that reproduces every worker diff byte-for-byte within disjoint declared write sets and has approval from a fresh isolated reviewer who was neither a worker nor the composer, or stop with no partial composition and identify the falsified worker node or split. |

## Inputs

Required inputs are one issue or pull request with its acceptance criteria, the local target workspace, the checks each worker and the composed result must satisfy, and named local locations for the checkpoint, isolated composition, and run report. Supply any fixed ordering constraints between units of work; otherwise the partition determines independent worker nodes. The target's current bytes and metadata are the composition base. The production task DAG is derived from the supplied units of work and their declared ordering constraints only.
