Does every segment declare the workload feature?
Record the weakest link and explicit display, PCIe, USB, or mixed-dock declarations.
Open Feature Path Checker →USB4 & Thunderbolt workbench
Plan rate, features, and tunnel demand separately.
A fast USB-C port does not automatically establish PCIe tunneling, display count, cable support, or application throughput.
Do the traffic budgets fit the planning share?
Add display, USB, and PCIe demand without predicting dynamic allocation.
Open Tunnel Budget Planner →What does this exact USB-C port establish?
Preserve data, power, display, PCIe, USB4, and unknown fields.
Open Port Capability Decoder →What minimum cable claims are required?
Build the combined power, data, video, and tunneled-use requirement.
Open Cable Requirement Selector →Which functions fail only through the dock?
Compare direct and dock-path power, data, and video observations.
Open Direct vs Dock Matrix →Which segment lowers the USB4 link class?
Compare target, observed class, segment declarations, direct control, and OS evidence.
Open Fallback Speed Isolator →How should USB4 and Thunderbolt claims be read?
Use a feature-first workflow for docks, enclosures, displays, and mixed loads.

Order: exact port and cable claims → required tunnel features → planning budget → direct-path control test.
