I found the following items to potentially revert:

Track: user-auth_20250115
  1) [Phase] Phase 2: Core Logic
  2) [Task] Task 2.1: Implement validation

3) A different Track, Task, or Phase

Which would you like to revert?

SHA abc1234 from plan.md not found in git history.
This may have been rewritten by rebase/squash.

Searching for similar commits...
Found: def5678 "feat(user): implement validation"

Is this the correct commit? (yes/no)

## Revert Execution Plan

**Target**: Task 2.1 "Implement user validation"
**Commits to Revert**: 2

1. `abc1234` - "feat(user): implement validation"
2. `def5678` - "conductor(plan): mark task 2.1 complete"

**Action**: Run `git revert --no-edit` on each commit (newest first)

Do you want to proceed?
A) Yes - execute the revert
B) No - cancel and review

# Extract SHA from plan.md
grep -oP '\[x\].*`\K[a-f0-9]{7}' plan.md

# Verify SHA exists
git cat-file -t <sha>

# Find commits that modified plan.md after implementation
git log --oneline -- path/to/plan.md | head -5

# Search by commit message similarity
git log --oneline --all | grep -i "implement validation"

# Search by file changes
git log --oneline --all -- src/models/user.py

# Find when track was added to registry
git log -p -- conductor/tracks.md | grep -B5 "Track: user-auth"

Before: [x] Task 2.1: Implement validation `abc1234`
After: [ ] Task 2.1: Implement validation

User: "Revert the last task I completed"

Agent:

3. Find plan-update commit: def5678
4. Present: "Revert Task 2.1? Will undo abc1234, def5678"
5. User confirms
6. Execute: git revert --no-edit def5678 && git revert --no-edit abc1234
7. Verify plan.md shows [ ] for task
8. Report success

User: "/smart-revert phase 2"

Agent:
1. Find all tasks in Phase 2 with [x] status
2. Collect all implementation SHAs
3. Collect all plan-update SHAs
4. Find phase checkpoint SHA
5. Present comprehensive plan
6. User confirms
7. Execute reverts in reverse order
8. Verify all Phase 2 tasks show [ ]
9. Report success

Agent: "Looking for SHA abc1234..."
Agent: "SHA not found. Checking for rebased commits..."
Agent: "Found similar commit def5678: 'feat(user): validation'"
Agent: "Is def5678 the correct replacement? (yes/no)"
User: "yes"
Agent: [continues with def5678]

const logicalUnitTracker = require('./.claude/lib/utils/logical-unit-tracker.cjs');

// Group commits by task ID from git notes
const groups = await logicalUnitTracker.groupByTask(repoPath, 'HEAD~10..HEAD');
// Returns: { "6": [{hash, message, note}], "7": [{...}] }

// Find dependencies
const deps = await logicalUnitTracker.findDependencies(repoPath, '7', { transitive: true });
// Returns: ["6"] if Task #7 depends on Task #6

// Check safety before reverting
const safety = await logicalUnitTracker.checkRevertSafety(repoPath, '6');
// Returns: { safe: boolean, blockers: [], warning: string }

// Execute revert for entire task
const result = await logicalUnitTracker.revertTask(repoPath, '6');
// Returns: { success: boolean, conflicts: boolean, message: string }

// Find task by name
const tasks = await logicalUnitTracker.findTaskByName(repoPath, 'Dark Mode');
// Returns: ["6"] if Task #6 has "Dark Mode" in notes

User: "Can we revert the dark mode feature?"

smart-revert workflow:
1. Find tasks by name: logicalUnitTracker.findTaskByName(repo, 'dark mode')
2. Found Task #6 with 2 commits
3. Check safety: logicalUnitTracker.checkRevertSafety(repo, '6')
4. Show plan:
   - Revert "Add dark mode toggle" (abc123)
   - Revert "Update CSS for dark mode" (def456)
5. User confirms
6. Execute: logicalUnitTracker.revertTask(repo, '6')
7. Result: "Dark mode reverted. 2 commits reverted successfully."

User: "Revert task #6"

smart-revert workflow:
1. Group commits: logicalUnitTracker.groupByTask(repo, 'HEAD')
2. Find Task #6 commits
3. Check dependencies: findDependencies(repo, '6')
4. No dependencies found
5. Execute revert in reverse order
6. Verify success

User: "Revert the button refactor"

smart-revert workflow:
1. Find Task #7 (Button Refactor)
2. Check safety: checkRevertSafety(repo, '7')
3. Warning: "Task #8 (Modal) depends on Task #7"
4. Offer options:
   - Revert both #7 and #8
   - Don't revert
   - Force revert (handle conflicts manually)
5. User selects option
6. Execute based on choice
