# HappyX SQLite Backup Restore Dry Run

Updated: 2026-05-22T22:15:57.943Z

## Purpose

This dry run creates a temporary file-backed SQLite database from the current JSON state, copies it as a backup artifact, restores that backup to a second temporary database and compares public-safe table counts and SQLite health checks.

## Results

| Table | Source DB rows | Restored DB rows |
| --- | ---: | ---: |
| schema_migrations | 1 | 1 |
| events | 78 | 78 |
| tasks | 63 | 63 |
| sessions | 2 | 2 |
| permissions | 6 | 6 |
| approval_uses | 3 | 3 |
| agent_runs | 19 | 19 |
| agent_run_outputs | 19 | 19 |

## Checks

- Migration dry run: pass
- Backup file created: pass
- Restore file created: pass
- Table counts match: pass
- Source integrity: ok
- Restored integrity: ok
- Source foreign-key check rows: 0
- Restored foreign-key check rows: 0

## Decision

The current SQLite migration output can be backed up and restored in the dry-run path.

## Follow-up

- Keep this as a release-gated dry run until production storage is explicitly switched from JSON to SQLite.
- Add timestamped backup retention and rollback selection before any file-backed production database is enabled.
- Keep public reports limited to table counts and health checks.
