+# Device model database (friendly names)
+
+The macOS companion app shows friendly Apple device model names in the **Instances** UI by mapping Apple model identifiers (e.g. `iPad16,6`, `Mac16,6`) to human-readable names.
+
+The mapping is vendored as JSON under:
+
+- `apps/macos/Sources/Clawdis/Resources/DeviceModels/`
+
+## Data source
+
+We currently vendor the mapping from the MIT-licensed repository:
+
+- `kyle-seongwoo-jun/apple-device-identifiers`
+
+To keep builds deterministic, the JSON files are pinned to specific upstream commits (recorded in `apps/macos/Sources/Clawdis/Resources/DeviceModels/NOTICE.md`).
+
+## Updating the database
+
+1. Pick the upstream commits you want to pin to (one for iOS, one for macOS).
+2. Update the commit hashes in `apps/macos/Sources/Clawdis/Resources/DeviceModels/NOTICE.md`.
+3. Re-download the JSON files, pinned to those commits:
+
+```bash
+IOS_COMMIT="<commit sha for ios-device-identifiers.json>"
+MAC_COMMIT="<commit sha for mac-device-identifiers.json>"
+
+curl -fsSL "https://raw.githubusercontent.com/kyle-seongwoo-jun/apple-device-identifiers/${IOS_COMMIT}/ios-device-identifiers.json" \
+  -o apps/macos/Sources/Clawdis/Resources/DeviceModels/ios-device-identifiers.json
+
+curl -fsSL "https://raw.githubusercontent.com/kyle-seongwoo-jun/apple-device-identifiers/${MAC_COMMIT}/mac-device-identifiers.json" \
+  -o apps/macos/Sources/Clawdis/Resources/DeviceModels/mac-device-identifiers.json
+```
+
+4. Ensure `apps/macos/Sources/Clawdis/Resources/DeviceModels/LICENSE.apple-device-identifiers.txt` still matches upstream (replace it if the upstream license changes).
+5. Verify the macOS app builds cleanly (no warnings):
+
+```bash
+swift build --package-path apps/macos
+```
+
