# HappyX SQLite Migration Dry Run

Updated: 2026-05-22T22:15:57.430Z

## Purpose

This dry run applies the executable SQLite schema in memory and imports the current JSON state into the transactional tables. It validates table shape, foreign-key behavior and approval-use uniqueness without writing a production database.

## Source

- State source: state.json
- Schema source: happyx/storage/schema.sql
- Execution mode: in-memory SQLite

## Import Counts

| Table | Source rows | Imported rows |
| --- | ---: | ---: |
| 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

- Schema tables present: pass
- Approval-use uniqueness: pass
- Foreign-key check rows: 0
- Missing approval references skipped: 0
- Missing approval-use permissions skipped: 0
- Private output rows imported as metadata only: 19

## Decision

The current JSON state is ready for the next SQLite migration scaffold step.

## Follow-up

- Keep production on JSON state until rollback export and file-backed SQLite open/backup flow are implemented.
- Preserve public projections through redaction.js after any storage swap.
- Continue running public verification before and after migration changes.
