References:
- saffah_cc_v41_260924, https://duck.ac/submission/99730: directly adapted complete public solution and
its specialized output/startup strategy. All upstream attributions below
are retained. The public submission has no separate license notice.
Idea: Establish our first online baseline using the strongest public solution.
No new algorithmic claim; use the exact inherited strategy to measure the
current target and identify which routines actually need improvement.
Experiment purpose: Test whether the baseline meets the required threshold;
stop this problem immediately if it does, otherwise optimize based on results.
