Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Path Traversal: Slash-separated date partitioning can escape the base path via dash-delimited tokens like '..' or '.', enabling writes outside the table directory.
Path Traversal: Record partition paths are not validated against the handle's expected partition, allowing writes to unintended partitions and potential path escape.
Concurrency Control Bypass: Inconsistent base-path normalization before hashing can cause lock-key divergence, letting concurrent writers bypass the intended lock.
