+### Workflow D: Sync Script Coverage
+
+Maintains `wiki/script-coverage.md` — one row per page in `wiki/concepts/`, judged
+against the script named in that file's `**Script:**` metadata field.
+
+1. Read `wiki/script-coverage.md` and note every row where `Pinned` is `yes`.
+2. Read the script and every page in `wiki/concepts/`.
+3. For each concept, decide `Status` and `Station`:
+   - `covered` — the script delivers the idea, whether or not it uses the page's name.
+   - `partial` — the script gestures at it but never lands it.
+   - `absent` — the script never reaches it.
+   - `Station` is one of the seven, a comma-separated list, `all`, or `—` when absent.
+4. **Never modify a row whose `Pinned` is `yes`** — not its status, not its station.
+   A pinned row is the user's judgment and outranks yours.
+5. Add rows for concept pages with no row. Remove rows whose concept page no longer exists.
+6. Update `**Last synced:**` to today.
+7. Update `index.md` and append a `sync` entry to `log.md`.
+
+Run this workflow:
+
+- at the end of any ingest that creates or modifies a page in `wiki/concepts/`
+- whenever the script file itself changes
+- on the explicit `sync script coverage` intent
+
+The coverage baseline is always the raw script. Ingesting the script into
+`wiki/sources/` does not change the baseline.
