 TOP500 and Epoch AI compute sources do not always provide usable coordinates. The unified Earth compute-center endpoint uses only valid source-provided coordinates or `compute_center_locations` dimension-table coordinates during the main map startup path; records without coordinates are returned as `unresolved` instead of being rendered from a local registry, country centroid, or guessed city. When users manually collect candidates, the backend queries ROR and Nominatim/OpenStreetMap from source fields; accepted candidates are saved into `compute_center_locations` and rendered from that table on the next layer refresh.
 
+Admin Next collection management follows the business hierarchy instead of flattening every endpoint into one table:
+
+- `Collectors`: endpoint, authentication, headers, base parameters, enabled state, and credential guides.
+- `Collection Schedule`: scheduler state and task controls.
+- `Collection History / Snapshots`: history grouped by collector, with a detail-side snapshot selector for versions.
+
+Snapshot lists should not show every snapshot of the same collector as separate top-level records. The top-level list selects a collector; the detail area switches between time versions.
+
+Credential guides are maintained by `backend/app/services/credential_guides.py`. The console uses read / generate / reset actions to load or create Markdown instructions. The frontend should render the guide Markdown for operators, not expose generation prompts or raw metadata.
