+### Datasource Directory Page
+
+[DataSources.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/DataSources/DataSources.tsx) is the datasource directory and collection operation page. It should not grow back into a configuration editor.
+
+Current page boundary:
+
+- Built-in and custom sources are merged as `UnifiedDataSource`.
+- The list shows type, state, last run, collection progress, and actions.
+- Clicking a name opens a read-only drawer.
+- Endpoint, headers, and config are displayed here, not edited.
+- Credential-bearing collectors point users to `Collection Management -> Collectors`.
+
+Keep this boundary: do not put custom datasource editing, built-in endpoint overrides, or credential forms back into `/datasources`. Those configuration entry points live at `/collection-management?tab=collector_credentials`.
+
+### Collectors Page
+
+[Settings.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/Settings/Settings.tsx) has three route modes: `/settings` for System Settings, `/earth-content` for Earth Content, and `/collection-management` for Collection Management. The `collector_credentials` tab is shown as `Collectors` under `/collection-management`.
+
+Current boundary:
+
+- The dropdown selects built-in collectors.
+- The plug icon beside the dropdown runs the health check.
+- Credential-bearing collectors place credential forms above base config.
+- Free collectors show endpoint, default endpoint, headers, timeout, and retry.
+- BarentsWatch AIS keeps its dedicated credential form.
+
+### Earth Content Page
+
+`/earth-content` reuses the same single-screen tab container from [Settings.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/Settings/Settings.tsx), but its ownership is separate from System Settings:
+
+- `TV Livestream` owns the Earth media-panel source configuration.
+- `Boundary Precision` owns the Earth static boundary asset state: provider, low-precision fallback, high-precision manifest/PMTiles, source JSON, and build action.
+- `Base Map`, `Layer Resources`, `3D Assets`, and `News Anchor Strategy` are placeholders only. They show module status and do not invent fake APIs or fake data.
+
+Do not add Earth experience resources or collection-lifecycle tabs back into `/settings`; collection belongs to `/collection-management`, and Earth display resources belong to `/earth-content`.
