- Handle nil l.Time by falling back to dbtime.Now() instead of storing
year-0001 timestamp.
- Wrap matched_rule with NULLIF in InsertBoundaryLogs SQL so empty
strings are stored as NULL, preserving IS NULL query semantics.
- Make ensureSession check for sql.ErrNoRows specifically; transient DB
errors, auth failures, and context cancellation no longer fall through
to an unnecessary INSERT attempt.
- Add maxBoundaryLogsPerBatch (1000) limit to reject oversized batches
that could cause unbounded memory allocation or query timeouts.
- Return early on empty req.Logs to avoid unnecessary session creation
and DB round-trips.
