# TrustMark Q model files for watermark toolkit

This repository mirrors the TrustMark `Q` model files used by the local watermark toolkit integration.

Files:

- `encoder_Q.ckpt`
- `decoder_Q.ckpt`
- `trustmark_Q.yaml`

The model is used through the Python package `trustmark>=0.9.1` and the toolkit's `TrustMarkEngine`.

Original project: https://github.com/adobe/trustmark

Industrial pattern used by this toolkit:

```text
payload -> SQLite/backend registry -> 8-character watermark_id -> TrustMark image watermark
image -> TrustMark decode watermark_id -> registry lookup -> full payload
```

The image carries only the short `watermark_id`; sensitive business payloads should remain in your registry/database.
