plan-pipeline-execute

Automated plan execution to a merged pull request is achieved by running the pipeline in an isolated worktree, coordinating tasks through per-task agents, and enforcing quality gates before PR delivery.

Worktree isolation creates a separate working directory to execute multi-step plans, enabling parallel task execution and drift detection without affecting the main branch until the quality gate passes and the PR merges.

Parallel task execution with automated quality gates runs level-based tasks through per-task agents, applies drift detection, executes smoke tests, and creates a pull request only after passing the required validation checks.

Automated plan pipeline execution requires a validated plan file located at docs/plans/plan-{name}.md, ensuring deterministic and auditable execution before any tasks are dispatched to per-task agents.

After the quality gate smoke test passes, the automated PR pipeline creates the pull request, manages the merge process, performs cleanup, and produces post-merge metrics for execution analysis.

Drift detection during parallel task execution monitors for divergences between the isolated worktree and the main branch, ensuring the automated quality gate catches conflicts before pull request delivery.
