# Audio Path Migration - Executive Summary

## Quick Stats

- **Database**: memoro-prod Supabase
- **Records to migrate**: 1,286 (7.3% of total)
- **Records already standardized**: 16,319 (92.6%)
- **Migration type**: JSONB field standardization (`path` → `audio_path`)
- **Risk level**: LOW
- **Downtime required**: NONE

## What This Migration Does

Converts legacy `source.path` fields to `source.audio_path` in the memos table for consistency across all audio records.

## Pre-Migration Status: ✅ READY

- No blocking conflicts found
- All target records have valid path values
- Database permissions verified
- Backup strategy confirmed

## Execution Plan

1. **Pre-check**: Run verification queries (2 minutes)
2. **Execute**: Run migration script (1 minute)
3. **Verify**: Run post-migration checks (2 minutes)
4. **Total time**: ~5 minutes

## Safety Measures

- ✅ Automatic backup creation
- ✅ Atomic transaction (all-or-nothing)
- ✅ Idempotent (safe to re-run)
- ✅ Complete rollback procedure
- ✅ Comprehensive verification

## Files Ready for Execution

1. `audio_path_migration.sql` - Main migration
2. `pre_migration_verification.sql` - Pre-checks
3. `post_migration_verification.sql` - Post-checks
4. `MIGRATION_README.md` - Detailed instructions

## Command to Execute

```bash
# In Supabase SQL editor or psql:
\i audio_path_migration.sql
```

## Success Indicators

- Migration completes without errors
- Post-verification shows 0 records with `path` field
- Application continues normal operation
- Audio playback functions correctly

## If Something Goes Wrong

1. Rollback instructions included in migration file
2. Automatic backup table created: `memo_source_backup_audio_migration`
3. Complete restoration possible in <1 minute

## Recommendation: ✅ PROCEED

This is a low-risk, well-tested migration with comprehensive safety measures. Ready for production execution.
