 ## Goal

 ## Plan
 
-[moq-dev/moq#6719](https://github.com/moq-dev/moq/pull/6719) found it failing
-the same way on `main` and on its branch: a probe resends a stream after that
-stream was reset. A reset stream's data is never retransmitted, so find which
-path still queues it (probe padding, a loss-recovery retransmit, or a stale
-send queue entry) and stop it there. The other probe tests in the release
-suite pass, so the fix must keep them passing.
+Over seeds 1 through 8, probing beside a Cubic upload averages 413.6 late
+frames versus 385.1 for the baseline, beyond the `LATE` budget. Find why
+probing adds delay beside Cubic and fix it in the transport. Keep the
+overhead, fairness, and rise budgets and the other probe scenarios passing.
+Do not relax the assertions or disable probing to make the scenario pass.
+
+Run the probe suite with release debug assertions and overflow checks, as
+`just rs quic-sim` does. `just rs test --release -p moq-quic --run-ignored all
+--no-fail-fast -E 'test(/^tests::probe::/)'` also includes the short gate cases.
