Public, reproducible benchmarks for this problem are scarce: existing routing benchmarks are static, while dynamic-fleet studies typically rely on private operator data. We introduce FreightBidBench, a public-calibrated, dependency-free, closed-loop benchmark in which feasibility (pickup reach, appointment windows, simplified hours-of-service, stochastic yard delays) and economics (service-failure penalty, terminal fleet value, daily price-premium window) are explicit, versioned, and reproducible from public Freight Analysis Framework and U.S. Department of Agriculture truck-rate data. Building on this benchmark, we make three contributions. First, we formalize the v0 .3 closed-loop accept/reject MDP and show that the three new reward components each isolate a distinct policy class: a service-failure penalty creates linear regret for feasibility-blind policies, terminal fleet value penalizes greedy positioning, and a temporal price-premium window penalizes future-blind timing. Second, we develop three complementary hindsight diagnostics: an exact realized-seed dynamic program for small load prefixes, a simple LP-style full-horizon upper bound, and a Lagrangian-per-truck information-relaxation bound that retains per-truck HOS and sequencing structure and is 20 . 7% tighter than the LP relaxation on tight and 39 .3% tighter on scarce while remaining dependency-free, justified as an information relaxation in the sense of Brown et al. [2010] . Third, we introduce a parametric surrogate-rollout cascade with two escalation triggers — a boundary band β ≥ 0 on the surrogate’s signed score and a scarcity-pressure threshold κ on the count of immediately available trucks in the origin market—characterize its limit behaviour (rollout-call share monotone in either trigger threshold), and show that the scarcity trigger alone captures the high-stakes capacity decisions on which the surrogate is least reliable. On ten-seed tight and scarce scenarios, the best simple policy retains 91.0 percent and  \n86.5 percent of rollout profit, respectively, and a stdlib linear surrogate 94.2 percent and 89.3 percent; a cascade at a single escalation band recovers roughly 98 percent of rollout value on both at 40–56 percent of rollout’s mean decision latency, and on tight is statistically indistinguishable from the rollout teacher (paired-bootstrap 95% CI on the profit delta spans zero) . The release contains a versioned manifest, layer ablations, sensitivity sweeps, and an exact-plus-relaxed ceiling, providing a reproducible test bed for future methods work.  \n∗ Code and benchmark artifacts: [https://github.com/aswincsekar/freightbidbench](https://github.com/aswincsekar/freightbidbench.

The decision is constrained by latency: tenders in a typical broker workflow must be priced and accepted or rejected within seconds. The decision is operationally constrained: a load can only be served by a truck that can reach the pickup, satisfies appointment windows and hours-of-service (HOS) clocks, and remains feasible through delivery. The decision is economically constrained: a tender with positive immediate margin can still be a poor decision if it consumes a scarce
