Review findings
- Selected sites, required IDs, complete whole-client assignments and capacity loads passed exact checks.
Lower bound: Each client may use its cheapest candidate; opening count, required sites and capacities relaxed.
The best checked cost is at most 40 above the optimum for this model. This is a bound on suboptimality, not a measured difference from a known optimum.
Best checked plan reduces submitted cost by 0.

Conventional solver
Optimal, as reported by the solver. Solver status and numerical bounds remain separate from independent optimality.
Input provenance
Generated computational control; no customer or geographic data.
Supplied provenance is not independently verified.

Evidence and scope
Exact frozen weighted assignment model only. No strict-metric/source-theorem eligibility, geographic validation or customer benefit is established.
Limits: 512 clients, 128 sites, eight MiB per file, sixteen MiB combined and 128-bit rational input components. Optional solver: two seconds, one worker; exact scales capped at one million and integer range capped conservatively.
