feat(M13.4): link Yukawa Compton cutoff to Ryu-Takayanagi entropy

[jagg-ix]

M13.4

Builds on M13.3 by using the Yukawa-generated Compton wavelength as an explicit ultraviolet-cutoff adapter for the finite Ryu--Takayanagi/CFT interval entropy.

Executable bridge

• computes the supplied Yukawa mass and Compton cutoff;
• evaluates the Brown--Henneaux central charge and vacuum interval entropy;
• reconstructs the RT area through S=A/(4G);
• verifies that interval and cutoff sharing one dilation leave the entropy invariant;
• checks the derivative of the entropy with respect to logarithmic mass;
• recovers the same mass and Compton frequency from the conditional horizon-area-rate mass bridge.

Formal authority

Pins the exact RT, horizon-entropy mass, three-origin Compton-clock, Yukawa entropy-rate, and scale-dilation source blobs on entropic-physlib-linear-full@8bafa9ab.

Claim boundary

The Compton wavelength is an explicit model choice for the RT/CFT cutoff. The equality between Yukawa mass and horizon-area-rate mass remains a supplied bridge hypothesis. RT minimal-surface area is not identified with horizon area growth.

Validation

• Python compilation passed;
• formal ledger parsed;
• focused M13.4 test passed;
• all 6 acceptance groups passed;
• one commit ahead and zero behind M13.3;
• no workflow file was added or modified.

Validation audit:

• primary M13.4 implementation blob matches the locally tested file exactly: 69e4cced81c626bf908f1919b1721624c36b2527;
• local Python compilation, ledger parsing, focused test, and all 6 acceptance groups passed;
• GitHub reports the PR mergeable with one commit and seven isolated files;
• existing workflow run 30531186960 completed successfully.

The attached workflow is the repository's existing M11 compile/ledger/test job; it is green but does not replace the focused M13.4 local campaign. No workflow file was added or modified.

Superseded by #164. The complete M13.4 Yukawa/Compton RT bridge is preserved there together with M13.5 in one direct-to-main commit. This PR is being closed without merging.
