# Data Model: Native Image Deployment

**Branch**: `005-native-image-deployment` | **Date**: 2026-04-07

## Summary

This feature introduces **no new data entities**. It is a build and packaging change only.

The existing data model (books, sections, figures, messages, pgvector embeddings) is unchanged.
All Flyway migrations run identically in native mode as in JVM mode.

## Impact on Existing Entities

| Entity | Change |
|--------|--------|
| Books | None |
| Sections | None |
| Figures | None |
| Messages | None |
| pgvector embeddings | None |

## Configuration Properties (new/changed)

The following new or updated configuration properties are added for native deployment:

| Property | Description | Default |
|----------|-------------|---------|
| `jib.to.image` | Target Docker image name/tag | (set at build time) |
| `jib.to.auth.username` | Docker registry username | (CI env var) |
| `jib.to.auth.password` | Docker registry password | (CI env var) |

All runtime configuration (database URL, OpenAI API key, S3 credentials) remains in
`application.properties` / environment variables — unchanged.
