…thout stalling — promote MIXPROOF-P01 (#429) Baseline before the change: 13 stalls in 42 executions of Kani (relay-mix-quad) (31%). After it: 11 consecutive executions with no stall — 10 re-runs of #451's Kani run 35250155750 plus the push run on main bd74cfe — across seven runners, four of which had held a stall of this harness. Slowest 7m04s against the 60-minute cap. Under the old rate, 11 clean runs in a row has probability 0.69^11 = 1.6%. Code-free promotion (the two-commit rule): SWREQ-RELAY-MIXPROOF-P01 and FV-RELAY-MIXPROOF-001 implemented -> verified, with every job id, runner and duration recorded. Not claimed: that no Kani harness can stall again. Kani (relay-param) was cancelled at 52 min on main bd74cfe, its log no longer retrievable; that belongs to CIFLOW-P01 (v1.142).

The measurement this was waiting on
The 11 are 10 re-runs of #451's Kani run 35250155750 plus the push run on main
bd74cfe, on seven different runners — including ci-01-6, -7, -10 and -11, each of which had previously held a stall of this harness. Slowest 7m04s, against the 60-minute cap. Under the old rate, 11 clean runs in a row has a probability of 0.69^11 = 1.6%. Every job id, runner and duration is recorded in the artifact.Not claimed
That no Kani harness can stall again.
Kani (relay-param)was cancelled at 52 minutes on mainbd74cfe; its log is no longer retrievable, so the harness is unidentified, and it has been re-run. If the heavy tail is a property of large float instances rather than of this one harness, other legs will show it — that is CIFLOW-P01 (v1.142), not this artifact.🤖 Generated with Claude Code
