# HappyX SQLite Feature Flag Dry Run

Updated: 2026-05-22T23:07:14.671Z

## Purpose

This dry run verifies that file-backed SQLite can be opened behind an explicit feature flag and that temporary SQLite backups can be rotated and restored without switching production away from JSON state.

## Feature Flag

- Default storage mode: json-state
- Dry-run enabled mode: temporary-file-backed-sqlite
- Production storage switched: no
- Temporary database opened: yes

## Backup Rotation

- Keep newest backups: 3
- Maximum age hours: 24

| Backup | Age hours | Action | Reason | Fingerprint |
| --- | ---: | --- | --- | --- |
| backup-01 | 0 | keep | within-policy | d5680e8912f2fec8 |
| backup-02 | 1 | keep | within-policy | d5680e8912f2fec8 |
| backup-03 | 2 | keep | within-policy | d5680e8912f2fec8 |
| backup-04 | 28 | prune | outside-rotation-policy | d5680e8912f2fec8 |
| backup-05 | 52 | prune | outside-rotation-policy | d5680e8912f2fec8 |

## Restore Counts

| Table | Source rows | Restored rows |
| --- | ---: | ---: |
| schema_migrations | 1 | 1 |
| events | 78 | 78 |
| tasks | 70 | 70 |
| sessions | 2 | 2 |
| permissions | 6 | 6 |
| approval_uses | 3 | 3 |
| agent_runs | 19 | 19 |
| agent_run_outputs | 19 | 19 |

## Checks

- Feature flag default disabled: pass
- Temporary SQLite open: pass
- Source integrity: ok
- Source foreign-key check rows: 0
- Backup rotation keeps and prunes: pass
- Pruned backup files removed: pass
- Restored integrity: ok
- Restored foreign-key check rows: 0
- Restored table counts match: pass
- Production state unchanged: pass
- Temporary artifacts removed: pass

## Decision

Feature-flagged SQLite open and backup rotation are ready for a guarded implementation step.

## Follow-up

- Keep the feature flag disabled by default until an authenticated operator switch and rollback command exist.
- Add production backup retention only after pre-restore backup and rollback selection are implemented.
- Continue publishing public reports with counts, health checks and short fingerprints only.
