 ## Notes
 
+The tables page now supports manual curation of imported critical-table cells. Hovering a populated cell shows that it is editable, and clicking opens a popup editor for the full `CriticalResult` record plus its nested `CriticalBranch` and `CriticalEffect` rows.
+
 The current database is an initial seeded subset designed to prove the full lookup workflow. The existing schema notes in `critical_tables_db_model.md` and `critical_tables_schema.sql` are still useful as the source of truth for expanding the import pipeline and normalizing more of the official tables.

 7. Route image PDFs like `Void.pdf` through OCR before the same parser.
 
 The important design decision is: never throw away the original text. The prose is too irregular to rely on normalized fields alone.
+
+## Manual curation workflow
+
+Because the import path depends on OCR, PDF XML extraction, and heuristics, the web app now treats manual repair as a first-class capability instead of an out-of-band database operation.
+
+Current curation flow:
+
+1. Browse a table on the `/tables` page.
+2. Hover a populated cell to identify editable entries.
+3. Open the popup editor for that cell.
+4. Edit the entire `critical_result` graph:
+   - base raw cell text
+   - curated prose / description
+   - raw affix text
+   - parse status
+   - parsed JSON
+   - nested `critical_branch` rows
+   - nested `critical_effect` rows for both the base result and branches
+5. Save the result back through the API.
+
+The corresponding API endpoints are:
+
+- `GET /api/tables/critical/{slug}/cells/{resultId}`
+- `PUT /api/tables/critical/{slug}/cells/{resultId}`
+
+The save operation replaces the stored branches and effects for that cell with the submitted payload. That keeps manual edits deterministic and avoids trying to reconcile partial child-row diffs against importer-generated data.
