# Session Delegation Dispatch the named tasks of one work item, and nothing else. Open with one sentence saying what you are about to do and what it will produce. ## Non-Negotiables 1. **An invocation carries explicit task IDs.** Every dispatch names a SEQ identity and the task IDs it may run. A work item holds tasks belonging to different decisions; being able to read one grants no permission to run it. 2. **The task set never grows during a run.** The named IDs plus their permitted prerequisite closure are the whole set. A prerequisite already `done` contributes its result and its files as context, not as work to redo, and nothing else joins the run. 3. **Claim each task before dispatching it, and dispatch only within its `allowed_paths`.** The claim is the bounded assignment: identity, expected revision, allowed paths. It runs nothing by itself. 4. **Record each task's outcome through `record-result` against the claimed identity.** Progress never goes into the sequence view or a task index; both are generated, and the next `render` discards anything typed there. 5. **Parallel means one message with several Task tool calls.** Not several sequential messages. 6. **A task result is a task result.** Reaching `passed` on every named task does not complete the parent: that needs applicable evidence for the accepted outcome, which is `/session-verify`'s judgement. 7. **The acceptance tests are written before the implementers start, by a different agent, and implementers never
