What a geometric successor must add

A gravitational use of the word “wormhole” would require, in one identified model:

1. a metric or justified effective geometry, with the proposed mouths and throat identified;

2. gravitational equations and justified stress assumptions, including the relevant energy-condition properties;

3. causal structure and boundary conditions;

4. an injection, propagation, and extraction experiment supporting a geometric signal-crossing claim;

5. all inaccessible outputs and a physical receiver;

6. quantitative comparisons from the microscopic processes to the finite channel certificate.

The gravitational constructions in the external literature add specific couplings and backreaction; an entangled resource alone does not reproduce them GaoJafferisWall,MaldacenaStanfordYang. Em03-A's prescribed Schwarzschild emission calculation is a different fixed-background construction CheungEm03AF. Neither it nor ER $=$ EPR identifies the present interface with a material transport path.

spacecraft reading. If a future model genuinely encoded the relevant spacecraft state, preserved the required reference correlations, supplied the communication resources, and implemented the declared receiver, then the theorem would bound the error of that logical state return. The present paper supplies none of the missing physical identifications. It cannot predict passenger survival, displacement, proper time, propulsion energy, or the fate of a gravitational remnant.

. The extrapolation makes quantitative predictions about information tasks and their resources. It does not turn the analogy into a geometry. The ship is a declared code, the passage is a receiver contract, and the convoy is a separately declared composition.
