+  This is the resumed half of a real macOS receiver interruption against exact
+  firmware commit `483ace3`. It contains 2,576 contiguous samples, sequences
+  1,992 through 4,567, with zero packet/sample gaps, resets, CRC failures,
+  reported drops, loop overruns, trailing bytes, or timestamp saturation. The
+  final status records one disconnect and one deliberate frame replay, with
+  zero notification failures or invalid ACKs. It validates that the 10.24-second
+  queue covered the measured resubscription interval without permanent loss.
 
 `tests/test_trikke_protocol.py` verifies the hashes, parses the captures in
 fragmented chunks, and asserts these signatures so the hardware evidence remains
