Better Auth rate_limit table migration exists on branch but hasn't been deployed to UAT. Switching to memory storage bypasses the missing table entirely, restoring auth functionality immediately. Memory storage is per-instance (not shared) — rate limiting still functions but won't be distributed across pods. This is acceptable for UAT while the migration is being promoted through the pipeline. Co-Authored-By: Paperclip <noreply@paperclip.ing>
