Summary

• Make Dispatch coordinate and delegate substantive work, including single-file changes; reserve DIY for obvious mechanical corrections.
• Preserve named routing, typed worker briefs, collection modes, and review regardless of file count; route unfinished work back to its owner.
• Measure primary file mutations and require delegation without parent edits on substantive capability cases, scoped to Dispatch so leaf overlays retain valid behavior.

Verification

• bun run check passes: 8,170 tests, zero failures.
• Focused prompt, metric, eval-parser, and runner checks pass: 139 tests.
• Leaf-overlay eval dry-run passes without inference. Live-model routing and custom-vLLM probes are not run.

Independent review covers the Dispatch card, override guidance, capability mutation metric, director-scoped behavior bounds, tests, and architecture docs. The original leaf-overlay regression is resolved: only default/explicit Dispatch runs receive delegation bounds, and leaf runs retain universal discipline checks. Final review has no remaining actionable findings. Full bun run check passes (8,170 tests); focused checks pass (139). This is prompt policy, not a hard tool gate; live-model routing is not measured.
