File not found
An API or grant mint looked up a file id and found no active row. Product text includes the period: “File not found.”
Why this happens
Wrong id, deleted/trashed file, or treating a folder id as a file. Common on /api/download/grant, member/API download routes, and some comment access paths that 404 as file-missing.
Diagnose and fix
1. Confirm the public/file id still exists and is active.
2. At mint time this means the landing page already lost the file — share a new URL after restore.
3. API clients: verify you are not sending a folder id.
4. Sibling title-only File not found (page title) is SSR metadata without the period.
