fix: Code fix to handle replan request

[chaudhariniraj]

Purpose

Code fix to handle replan requests.

Issue

When a user creates a task for the Retail Success Team for the first time, the Magentic orchestrator may not gather sufficient information to confidently complete the task. As a result, it triggers a replanning event during workflow execution.

The replanning event generates a new MagenticPlanReviewRequest, which was being handled the same way as the initial plan review. Consequently, orchestration_manager.py invoked _handle_plan_reviews() again, causing the workflow to pause and wait for user approval a second time.

This resulted in the user being redirected back to the "Approve Plan" screen, giving the impression that the workflow had failed, even though the orchestration was still active.

---

Fix

Introduced a plan_already_approved flag to track whether the user has already approved the workflow plan.

plan_already_approved = False

Workflow

1. When the user approves the initial plan, the flag is set to True.
2. If a replanning event occurs after the initial approval, the workflow skips the _handle_plan_reviews() method, which would otherwise:
   • Send another PLAN_APPROVAL_REQUEST to the UI.
   • Pause the workflow.
   • Wait for user approval again.
3. Instead, replanned workflows are automatically approved by generating approval responses programmatically:

plan_responses = {
    request_id: plan_review.approve()
    for request_id, plan_review in plan_requests.items()
}

Benefits

• Prevents users from being sent back to the Approve Plan screen during internal replanning.
• Allows Magentic to continue executing replanned workflows without interruption.
• Preserves the framework's replanning capability while improving the user experience.
• Ensures that only the initial workflow plan requires explicit user approval.

Does this introduce a breaking change?

• Yes
