## Summary Fixes an authorization bug in `requires_access_backfill` where an unknown `backfill_id` could be distinguished from a forbidden one by response status code, leaking which backfill ids exist. ## Root Cause When `backfill_id` was present but matched no row, `dag_id` stayed `None` — the same as when there was no `backfill_id` at all — so the check fell through to authorizing against a `dag_id` from the request body instead of denying outright. ## Fix If `backfill_id` is given but matches no row, deny immediately with `403 Forbidden` (the same response a forbidden-but-existing backfill gets), instead of falling back to the body-supplied `dag_id`.
