audit: an absence already filed as the rig's has answered the wedge question

check_a_wedged_gateway_is_named_as_one demanded the words 'recover' or
'restart' in the detail. busbar anthropic>anthropic came back with
reason=harness_error and the impossibility spelled out - c=4096 failing after
the cell had carried c=8192, which cannot be the gateway - and this still called
it unexplained.

That is the third false positive of the same family, and they share a cause:
these checks were grading prose instead of reading what the absence claims. An
absence the engine has already filed as harness_error or rig_limited has
reached the same conclusion by a stricter route than any keyword match.

Also commits agentgateway's snapshot, pulled by hand after the orchestrator died
mid-run on 2026-08-01.
