5-sample pivot selection

Measurements

Metric	BaselineThe benchmark measurement of the unmodified code	CandidateThe code with the proposed optimization applied	DeltaThe performance change from baseline to candidate
sort_time_us (us) primary	383.000 us (n=1)	412.000 us (n=1)	+7.57% REGRESSED

Annotations

hypothesis	5-sample sorted pivot selection for better partition quality
next_action_hint	keep simple pivot selection, try reducing overhead in inner loop or different algorithmic approach
rollback_reason	7.6% regression — sorting network overhead exceeds partition quality gains at n=10k

Base CommitThe starting commit before the optimization was applied	b1169abb7d849bab97245f900c73103e1ba9db09
Candidate CommitThe code with the proposed optimization applied	b1169abb7d849bab97245f900c73103e1ba9db09
