dispatch

Parallel implementation is orchestrated by coordinating sub-agent work across planning, execution, merging, and phase continuation for a named delta bundle. An active phase sheet must define multiple tasks with potential dependencies to enable this.

Worktree isolation is applied only when safe, requiring explicit disjointness or positive evidence of no dependencies. The system enforces branch-point checks before spawning workers to ensure safe isolation of parallelizable file-scope work.

Token budgeting for sub-agent dispatch is managed by estimating per-task complexity and batching work to fit worker capacity. The system automatically chooses between sonnet and opus model escalation based on these complexity estimates.

Verification commands are read from project configuration and workers must verify their changes before merges are accepted. The system merges worktree worker branches with conflict reporting and re-runs verification on the merged results.

Sub-agent dispatch is not suitable when an active phase sheet lacks multiple tasks with potential dependencies. It also requires parallelizable file-scope work that can be safely isolated, so tightly coupled tasks without disjointness should be avoided.

A delta bundle is a multi-phase unit of work that the orchestration process drives to completion across planning, parallel implementation, merging, and continuation phases without requiring user micromanagement of sub-agents.
