Gas and PDP Network Evidence BlueChips has two public evidence threads relevant to gas and flow-network review. First, the FIBI and Sheaf Sweep-Cut work evaluates industrial process isolation across chemical, natural gas, and electric power networks. The natural-gas case uses GasLib-4197, a 4,197-node and 20-zone benchmark. The important public claim is not that every gas subproblem is solved by one score. The claim is that the workflow returns physically actuatable isolation cuts rather than only variable rankings. Second, the deterministic residual-corrector work includes a PDP and well-test derivative target alongside pressure drawdown and fracture-network cases. The public result reports improvement over the best classical radial spectral-transfer baseline on that target. Together, these artifacts support gas and reservoir-flow positioning as evidence-backed network and residual-correction work. They should be used as technical support for critical-network containment, risk evidence, and energy-system review rather than as a standalone public product claim. Non-public valve models, operating traces, proprietary assets, and customer-specific field data remain controlled review material.
