Nothing in the workspace compared any number to 100,000 events/s while the evidence file reported "AM-6 | met, 16.5x". Now a test does — a test, not a bench, because Criterion reports throughput and asserts nothing, which is why this row measured nothing for six passes. Measured on bnt-lap001: 341,280 ev/s in debug (3.4x the target), ~2.4-3.1M in release. The spec target holds even in an unoptimized build, so the gate needs no cfg split and runs in the ordinary `make test`. The trap this task named — loosening a flaky timing assertion until it never fires — is avoided by construction. The threshold is the spec value, untouched; the constant says lowering it requires an ADR; and the failure message repeats that, states measured headroom, and names reference figures, so an agent hitting a red AM-6 is told not to tune it in the place they are actually reading. Robustness comes from best-of-N, not from a lower bar: a throughput floor asks whether the machine is capable, so transient load should not fail the build. Two positive controls in the test: a run that applied fewer than 50,000 events, or measured zero elapsed time, fails rather than scoring as infinite throughput. Verified by a PROPERTY mutation — 4,000 black_box iterations injected into GroundState::fold, the hot path — not a threshold tweak, which would only prove the comparison runs. And the FA class found last pass is now gated. mutation-check rows gained an `expect` field: the mutant's output must contain the row's stated failure string or the verdict is WRONG-REASON, not red. Without it a mutation that merely failed to compile would credit its row with an assertion it does not have. Verified by pointing expect at a string the verifier never prints and watching the verdict flip. This is remedy (2) from the CB-WP-0005 retrospective, built a task earlier than planned because the class it guards is the newest and most dangerous. M-D1-MUT: 4 -> 5 of 14.
