## Database source-data review

EWR's `scripts/build_db.py` says its database merges facts from the following
sources. The script fetches live branches, and the committed database has no
per-field provenance sidecar. PrinterCare does not know which source contributed
each shipped model parameter. These entries describe possible derived data, not
separately bundled source files.

| Name | Version / commit | Source URL | License stated in EWR script | How used | Bundled as separate file | Modified | Required notices | Commercial redistribution reviewed |
| --- | --- | --- | --- | --- | --- | --- | --- | --- |
| reinkpy | Not pinned | https://codeberg.org/atufi/reinkpy | AGPL-3.0 | Database write-path base | No; possible derived facts in database | Unknown upstream history | To determine | **No** |
| ez-reset | Not pinned | https://github.com/CiRIP/ez-reset | No license identified by EWR script | Counter maps, limits, commit steps, names | No; possible derived facts in database | Unknown upstream history | To determine | **No** |
| reink | Not pinned | https://github.com/lion-simba/reink | GPL-3.0-or-later | Older model data and cross-checks | No; possible derived facts in database | Unknown upstream history | To determine | **No** |
| Gutenprint | Not pinned | https://gutenprint.sourceforge.net/ | GPL-2.0-or-later | Model names and aliases | No; possible derived facts in database | Unknown upstream history | To determine | **No** |

Before commercial distribution, review the database's source-by-source license
chain and the exact final installer contents. Do not infer that the EWR code's
Apache-2.0 license automatically covers data incorporated from other projects.
