# Validation Report — Baltique OS Core 0.78.4

## Scope

Validated release package for:

- Enterprise Version Guard 0.78.4
- Enterprise Case Spine 0.78.4
- Runtime Preflight version-aware repair
- Enterprise Shell `core_version_0783` repair

## Static validation

Planned checks:

- Required files exist.
- `BALT_VERSION` is `0.78.4`.
- Bootstrap loads Version Guard and Case Spine.
- Runtime Preflight no longer hardcodes the old exact `0.78.2` version failure.
- Runtime Preflight checks Enterprise Case Spine schema.
- Enterprise Shell includes Case Spine in navigation.
- Enterprise Shell does not downgrade `core_version` after 0.78.4.
- Migration 089 contains Version Guard and Case Spine DDL.
- PHP lint passes for all PHP files in the release package.

## Database validation

Not executed in this sandbox because there is no live Baltique OS MySQL server attached. Runtime database validation must be performed on the target server by opening:

```text
/upgrade_0_78_4.php
/system_runtime_preflight.php
/system_case_spine.php
```

## Expected post-upgrade state

- `app_settings.core_version = 0.78.4`
- `app_settings.schema_version = 0.78.4`
- Enterprise Shell check `core_version_0783 = OK`
- Runtime Preflight no longer reports that `0.78.3` or `0.78.4` is invalid because it is not exactly `0.78.2`
- `enterprise_case_spine`, `enterprise_case_events`, `enterprise_case_links` exist
- Module Registry contains `enterprisecasespine`

## Executed static validation in build sandbox
