Provide technical opinion on test determinism vs random values

[Copilot]

Description

Responded to review feedback requesting opinion on whether random.uniform() in test at lines 309-310 should be replaced with deterministic midpoint calculation.

Context: Test uses random position between waypoints to verify cost monotonicity. Original reviewer suggested deterministic midpoint; maintainer argued capped random values are acceptable.

Opinion provided: Agreed with deterministic approach because:

• Non-deterministic tests create flaky CI regardless of value bounds
• Failures become non-reproducible, hindering debugging
• Randomness adds no value for monotonicity checks
• If multiple positions needed, use parametrized test cases with fixed values instead

No code changes made per explicit instruction "DO NOT make a new branch and solve this."

Verification

• Reviewed test implementation and assertions
• Analyzed testing goals and random value usage
• Provided technical recommendation
