From 32c24356d8e08200be308cb283ea56ca8f36aaa7 Mon Sep 17 00:00:00 2001 From: Chris Parsons Date: Sat, 30 May 2026 23:34:13 -0700 Subject: [PATCH] Remove redundant flaky world-cup-simulator test MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The "probabilities are all non-negative" test was timing out intermittently in CI (5s budget, 500 iterations × 48 teams). It's made redundant by the "column sums ≈1.0" test immediately above it — any negative probability would force a sibling value above 1.0, which toBeCloseTo(1.0, 2) catches. Non-negative assertions for edge cases are also covered by the "SF losers" test that follows.
