revert

<user_request> $ARGUMENTS </user_request>

  **Before starting**, create todo list with these 5 phases:
  1. Scope Selection - Identify what to revert (track/phase/task)
  2. Impact Analysis - Find commits, files, status changes
  3. User Confirmation - Present impact and get approval
  4. Execution - Create revert commits and update files
  5. Validation - Verify consistency and report results

  **Update continuously**:
  - Mark "in_progress" when starting each phase
  - Mark "completed" immediately after finishing
  - Keep only ONE phase "in_progress" at a time
</todowrite_requirement>

<confirmation_required>
  ALWAYS require explicit user confirmation before:
  - Reverting any commits
  - Modifying plan.md status
  - Deleting track files

  Show exactly what will be changed BEFORE doing it.
</confirmation_required>

<non_destructive_default>
  Default to creating revert commits, not force-pushing.
  Preserve git history unless user explicitly requests otherwise.
</non_destructive_default>

<state_validation>
  After any revert:
  1. Verify plan.md matches git state
  2. Verify metadata.json is consistent
  3. Run project quality checks
  4. Report any inconsistencies
</state_validation>

</critical_constraints>

<core_principles> Revert by logical units (track/phase/task), not raw commits. A task might have multiple commits - revert them together.

<principle name="Preview Before Action" priority="critical">
  Show user exactly what will be reverted before doing it.
  List commits, files, status changes.
</principle>

<principle name="Graceful Degradation" priority="high">
  If full revert fails, offer partial revert options.
  Never leave project in inconsistent state.
