boundary. This manuscript supplies proofs, not an asserted physical identification. Its positive results are Theorems thm:derived, thm:calibrated, thm:competition, and thm:main. The last is explicitly conditional on a physical acceptance package. Section sec:obligations records the remaining physical obligations O1–O6.

and identifier correction. The supplied En10-A.tex concerns the finite qubit–antiqubit instrument CheungEn10A. The relational clock manuscript in the supplied excerpts is En09-A.tex, version 1 CheungEn09A. The predecessor's references to a relational “source En10-A@1” are therefore read as references to En09-A@1, not as a second manuscript with the same En10-A identifier. No unprovided registered revision is inferred.
