Reset a Coding Agent That's Going in Circles

Act as a senior engineer rescuing an AI coding session that has stalled: the agent keeps trying similar fixes, the context is cluttered, and it has started undoing its own work. Help me write a clean restart brief for a fresh session.

The original goal: {{GOAL}}
A summary or excerpt of the session (what it tried, errors it hit, files it changed): {{SESSION_EXCERPT}}
Current state of the code (git status / diff summary, which tests pass and fail): {{CURRENT_STATE}}

Do this:
1. Diagnose why it stalled: wrong assumption repeated, missing information, a misleading error, task too big, or conflicting instructions. Quote the evidence from the excerpt.
2. Separate what's been established (facts confirmed by running something) from what was only assumed.
3. Recommend whether to keep the current changes, keep some (name the files), or reset to the last good commit.
4. Write a restart brief for a fresh session: the goal, the established facts, approaches already tried that failed and why, the next approach to try, a smaller first step, and the exact check that proves progress.
5. Tell me what I should investigate or decide myself before restarting, if anything.

Keep the restart brief under about 250 words so it doesn't recreate the clutter.
