what does comprehensive mean in the domain of Physics?

To ensure coverage of Physics we need to enumerate what coverage would mean. Three paradigms are

• topics-based scope; see https://en.wikipedia.org/wiki/Outline_of_physics#Branches_of_physics
• classical mechanics
• thermodynamics
• quantum mechanics
• electrodynamics
• electrical circuits
• astrophysics
• particle physics
• formula-based (or concept-based) scope; see https://en.wikipedia.org/wiki/Lists_of_physics_equations
• F = m a
• E = m c^2
• Maxwell's equations
• Schrodinger's equation
• Wave equation
• conservation of momentum
• conservation of energy
• uncertainty principle
• equations of motion
• symbol-based scope; see https://en.wikipedia.org/wiki/List_of_common_physics_notations
• energy
• wave function
• mass
• acceleration
• position
• momentum

If the Physics Derivation Graph can demonstrate utility in each category, that provides evidence towards the claim that the Graph can be comprehensive.

That is distinct from a second, separate question of determining connectivity.
