@@ -78,6 +78,15 @@ When content changes, `clear_cache.js` only invalidates SSR entries that depend
     - `col:id` OR `col:*` on `PUT`/`DELETE`
     - everything on manual clear (`POST /ssr?clear=1` with no collection context)
 
+
+## Limit: 1 ensures precise dependencies
+
+By default, an API query for a collection (like `/api/v1/_/content?filter=...`) sets a list dependency `collection:*`. This means *any* change to ANY entry in that collection will clear the SSR cache for this page. 
+
+If you are querying a single document (like a page or article based on its path or slug), you should ALWAYS append `limit: 1` to your API call (or pass `limit=1` to `getDBEntries`).
+
+When `api/hooks/lib/ssr-server.js` intercepts a request with `limit === 1` and exactly one result is returned, it will register a precise `collection:id` dependency instead of a wildcard `collection:*`. This optimizes the cache drastically, because edits to *other* pages won't invalidate this page.

 ## How SSR data loading is supposed to work
 
 - Keep `frontend/src/ssr.ts` thin. It should set up locale state and call `render(App, { props: { url } })`.
