**The AIOX rollback command restores projects from the modular v4.0.4 structure to the legacy v2.0 layout by locating backups, removing new directories, and restoring original files with full metadata preservation.**

The **SynkraAI/aiox-core** repository ships a production-ready state recovery system accessible through the CLI command `aiox migrate rollback`. This implementation enables developers to safely revert failed migrations from the legacy v2.0 layout to the new modular v4.0.4 structure, ensuring projects can always return to a known good state.

## Architecture of the Rollback System

The rollback process follows a six-step pipeline orchestrated by `executeRollback(projectRoot, options)` in [`.aiox-core/cli/commands/migrate/rollback.js`](https://github.com/SynkraAI/aiox-core/blob/main/.aiox-core/cli/commands/migrate/rollback.js):

1. **Backup Discovery**: Locates the most recent `.aiox-backup-<date>` directory or accepts a user-supplied path through `findLatestBackup` and `verifyBackup` from [`.aiox-core/cli/commands/migrate/backup.js`](https://github.com/SynkraAI/aiox-core/blob/main/.aiox-core/cli/commands/migrate/backup.js).

2. **Structure Removal**: Deletes modular v4.0.4 directories (`core`, `development`, `product`, `infrastructure`) using the `removeV21Structure` function.

3. **File Restoration**: Iterates the backup manifest to copy files back to original locations with preserved timestamps and permissions via `restoreFromBackup` and `copyFileWithMetadata`.

4. **State Cleanup**: Removes temporary migration metadata through `clearMigrationState` defined in [`.aiox-core/cli/commands/migrate/execute.js`](https://github.com/SynkraAI/aiox-core/blob/main/.aiox-core/cli/commands/migrate/execute.js).

5. **Validation**: Verifies that at least two of three core directories (`agents`, `tasks`, `registry`) exist to confirm restoration completeness.

6. **Reporting**: Formats results through `formatRollbackSummary` for human-readable terminal output.

## Core Implementation in rollback.js

The main entry point coordinates recovery by accepting a project root and options object:

```javascript
// .aiox-core/cli/commands/migrate/rollback.js
async function executeRollback(projectRoot, options = {}) {
  // 1. Locate backup
  const backup = options.backupPath
    ? await loadBackupFromPath(options.backupPath)
    : await findLatestBackup(projectRoot);
  if (!backup) throw new Error('No backup found');

  // 2. Delete v4.0.4 directories
  const aioxCoreDir = path.join(projectRoot, '.aiox-core');
  const removal = await removeV21Structure(aioxCoreDir, { onProgress });

  // 3. Restore files from backup
  const restore = await restoreFromBackup(backup, projectRoot, { onProgress });

  // 4. Clean migration metadata
  await clearMigrationState(projectRoot);

  // 5. Return structured result
  return { success: restore.success, backup, removal, restore };
}

```

## Pre-Execution Validation

Before initiating recovery, call `canRollback(projectRoot)` to verify backup existence and checksum integrity. This prevents failed restore attempts when backups are missing or corrupted, providing a `reason` property explaining why rollback is unavailable.

```javascript
const { canRollback } = require('.aiox-core/cli/commands/migrate/rollback');

const status = await canRollback(projectRoot);
if (!status.canRollback) {
  console.error('Rollback not possible:', status.reason);
  return;
}

```

## CLI Usage and Commands

The rollback command registers under the migration CLI in [`.aiox-core/cli/commands/migrate/index.js`](https://github.com/SynkraAI/aiox-core/blob/main/.aiox-core/cli/commands/migrate/index.js):

```bash

# Auto-detect latest backup

aiox migrate rollback

# Specify explicit backup directory

aiox migrate rollback --backup .aiox-backup-2023-09-15

# Enable verbose output

aiox migrate rollback --verbose

```

Note that the `--dry-run` flag is **not** applicable to rollback operations.

## Programmatic Implementation

Integrate rollback into custom scripts using the exported API from `.aiox-core/cli/commands/migrate/rollback`:

```javascript
const { executeRollback, canRollback } = require('.aiox-core/cli/commands/migrate/rollback');
const path = require('path');

async function safeRollback() {
  const projectRoot = path.resolve(__dirname);
  
  const status = await canRollback(projectRoot);
  if (!status.canRollback) {
    console.error('Prerequisites not met:', status.reason);
    return;
  }

  const result = await executeRollback(projectRoot, {
    onProgress: console.log,
    verbose: true
  });

  console.log('Restoration complete:', result);
}

safeRollback().catch(err => console.error('Rollback failed:', err));

```

## CI/CD Integration

Implement automated recovery in GitHub Actions when migrations fail:

```yaml

# .github/workflows/aiox-rollback.yml

name: AIOX Rollback on Failure
on:
  workflow_run:
    workflows: ["AIOX Migration"]
    types: [completed]

jobs:
  rollback:
    if: ${{ failure() }}
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Install dependencies
        run: npm ci
      - name: Execute rollback
        run: npx aiox migrate rollback --verbose

```

## Summary

- The **rollback command** in AIOX restores projects from v4.0.4 modular structure to legacy v2.0 layout through six distinct phases: backup discovery, directory removal, file restoration, state cleanup, validation, and reporting.
- Core logic resides in [`.aiox-core/cli/commands/migrate/rollback.js`](https://github.com/SynkraAI/aiox-core/blob/main/.aiox-core/cli/commands/migrate/rollback.js) with helper functions imported from [`backup.js`](https://github.com/SynkraAI/aiox-core/blob/main/backup.js) and [`execute.js`](https://github.com/SynkraAI/aiox-core/blob/main/execute.js).
- Use `canRollback()` to validate backup integrity before attempting restoration.
- The CLI exposes functionality via `aiox migrate rollback` with optional `--backup` and `--verbose` flags.
- Programmatic integration requires importing `executeRollback` and handling the result object containing `success`, `backup`, `removal`, and `restore` details.

## Frequently Asked Questions

### How does AIOX locate the correct backup during rollback?

The system searches for directories matching the `.aiox-backup-<date>` pattern in the project root. If multiple backups exist, it selects the most recent one automatically. Users can override this behavior by passing a specific path via the `--backup` CLI option or `backupPath` property in the options object when calling `executeRollback()` programmatically.

### What validation ensures the restored project is complete?

After restoration, AIOX checks that at least two of the three core directories—`agents`, `tasks`, and `registry`—exist in the project root. If fewer than two are found, the system reports a warning indicating potential incomplete restoration. Additionally, `canRollback()` verifies backup checksums before any files are modified.

### Can I preview what the rollback will do before executing it?

No, the rollback command does not support `--dry-run` mode. Unlike the migration command, rollback always performs the restore operation once initiated. To mitigate risk, run `canRollback(projectRoot)` beforehand to confirm backup validity, or manually inspect the backup manifest in the `.aiox-backup-<date>` directory.

### Which files are removed during the rollback process?

The `removeV21Structure()` function deletes the modular v4.0.4 directories including `core`, `development`, `product`, and `infrastructure` from the `.aiox-core` path. It preserves any files in the project root that are not part of the v4.0.4 structure, ensuring only migration-generated artifacts are removed while restoring original v2.0 layout files from the backup.
