fix: make flocking scaling test robust against CI timing variance#1328
Merged
Conversation
The test was failing intermittently when the ratio exceeded 4.0 due to timing noise on CI machines. Changes: - Collect 7 samples per input size and use median (vs single measurement) - Add explicit warmup phase before measurements for JIT stability - Pre-create scenarios to avoid setup cost in measurements - Increase iterations per measurement from 20 to 30 - Raise threshold from 4.0 to 4.5 (still catches O(n²), tolerates variance) https://claude.ai/code/session_01NEFCJzmyQAHzvjgo3PSJ3S
