Security Notes
The server operates within a Cloudflare Workers sandboxed environment, which inherently mitigates many OS-level security risks. Optional Bearer token authentication via `API_SECRET` is available and recommended for production instances. Corrected documents stored in R2 use unique, non-guessable UUIDs for file names and have a 30-day auto-delete lifecycle policy. The code does not use `eval` or other dangerous dynamic code execution methods. R2 credentials (R2_ACCESS_KEY_ID, R2_SECRET_ACCESS_KEY) are required for the `upload-dictionaries.ts` *script* but are not hardcoded in the server's runtime code, instead relying on secure Cloudflare Workers bindings.
