  - `GET /` -> `200 OK`
  - `GET /api/v1` -> `200 OK`

## Findings

No blocking findings.

The stage satisfies the agreed scope:

- the SQLite schema covers the required tables;
- migrations are present and executable;
- migration checksum tracking is implemented and tested;
- the server startup path opens SQLite and auto-applies migrations;
- the health endpoint now reflects database readiness.

## Required Fixes

None.

## Optional Improvements

- Add explicit tests for `scope_mode` transition guard behavior, not just incompatible access-row insertion.
- Update the small home-page eyebrow copy from `Foundation Stage` to something database-specific for consistency.

## Status

`APPROVED`
