Conversation
After too many invalid recovery codes the next submit often carries a stale CSRF token, which hid the submitted-too-often result. Check the flow submit count before retrying as CSRF.
📝 WalkthroughWalkthroughThe recovery strategy now checks prior code submissions after CSRF validation fails. When the configured limit is reached, it returns the submitted-too-often response. The SQL persister and interface provide the required submission count. ChangesRecovery submission limit fallback
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to Recovery submissions can return a misleading CSRF error when the server cannot read the submission count, masking a backend failure and making the limit behavior unreliable. Fixing this error path is required before merge. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

Propagate a submission-count query failure.
Line 190 discards countErr. If the count query fails, this branch returns the CSRF retry response. The request then hides the persistence failure and cannot determine whether the submission limit applies.
Handle countErr through the established recovery error path before comparing submitCount.
