Executing engineering plans in isolated sessions requires orchestrating approved plan steps serially or in controlled batches with preflight validation and runtime checkpoints to maintain traceability and prevent cross-plan contamination.

Preflight validation in plan execution is a governance gate that verifies prerequisites and environment readiness before task mutations begin. It ensures protected-branch gating and runtime state compliance are satisfied prior to initiating any development steps.

To run task mutations serially with protected-branch gating, initiate an executing-plans run using an engineering-approved plan path. The session coordinates begin and complete task mutations while enforcing strict checkpoint governance between each step.

Plan execution supports controlled batching as an alternative to strict serial processing. Teams can run approved plan steps in controlled batches while maintaining preflight validation, post-task reviews, and runtime checkpoint reporting across the entire execution session.

An engineering-approved plan path is required to start an execution session. The orchestrator uses this approved plan to coordinate isolated session execution, enforce preflight checks, and manage runtime state for final review evidence.

Isolated sessions for plan execution should not be used when cross-plan contamination is impossible or when preflight validation and checkpoint governance are unnecessary. Simple, single-task changes without protected-branch gating requirements do not warrant isolated session overhead.
