OPT-12: HiGHS cross-query basis reuse

Performance interpretation is inconclusive. Paired medians and ranges are descriptive for these three synthetic LPs; the observed cold/warm ranges overlap. A separate source-mapped diagnostic profile locates sampled CPU work in the LP/HiGHS simplex path, but it does not attribute the measured cold/warm latency difference. Simplex iteration counts are reported separately. The measurements do not establish a warm-reuse advantage; they do not establish that warm reuse is slower. Measurements describe three synthetic LPs on the recorded host. They do not establish a general speedup or worst-case complexity change.

Source commit 7b732a53716ce963af83095fd2aeca8a681b76c4; adapter 1.1.0+highs.1.11.0; native solver HiGHS 1.11.0; Release.

Workload and independent checks

Each warm trial performs one unreported source solve in a fresh workspace, then solves the same changed LP as its paired cold trial. Measured results pass optimal-status, feasibility, and literal-objective checks. Side order alternates within each pair. Public-call wall time wraps LPWorkspace.solve; native load, basis-transfer setup, and solve intervals are reported separately.

Paired medians

Median cold and warm wall time and native component work

Native work sums model-load, basis-transfer, and solve intervals. It excludes independent result verification.

Separate source-mapped CPU profile

Separate PDB-enabled Release diagnostic run of the OPT-12 measurement executable with 20 paired repetitions; excluded from all latency statistics. It is a sampled CPU hotspot report; it does not attribute cold/warm latency differences. The trace contains 11623 target-process samples with no lost ETW events.

Diagnostic build used Release optimization with PDB symbols; it is separate from the measured executable. Raw ETL, symbolized stack report, and trace summary are in limiter-profile-evidence.zip. Profile metadata: limiter-profile.json.
