 ## What is blocked / remaining
 
 ### Action 3 — Facebook + Instagram credentials
-**Status:** BLOCKED — waiting on user
+**Status:** DEPLOYED but TOKEN INVALID — waiting on user to regenerate
 
-Current `FACEBOOK_DEFAULT_ACCESS_TOKEN` is expired (expired 2026-05-12). Instagram credentials are empty placeholders.
+Credentials were deployed to K8s from the Obsidian vault values, but Facebook API returns HTTP 500 "An unknown error has occurred" for all calls. Even `debug_token` and the old expired token now return 500, suggesting an app-level issue or corrupted token. User needs to re-test/regenerate the Page access token in Graph API Explorer.
 
 **Needed from Facebook Developer Console → Graph API Explorer:**
 - Page access token with scopes: `pages_manage_posts`, `pages_read_engagement`, `pages_show_list`, `instagram_basic`, `instagram_content_publish`
