Parallel coding agents make large migrations tractable
A large Bun pull request shows many independent agents working against explicit file boundaries and a common test contract.
Signal contract
- A large Bun pull request shows many independent agents working against explicit file boundaries and a common test contract.
- Parallelism creates leverage only when tasks are separable, ownership is explicit, integration is deterministic, and tests protect the shared boundary.
- Novelty: notable. Verification: source-inspected.
