X4-DMSD: Exact X–Four-Edge Joint Constraint Domains with Decimal Multiscale Search
Proposes searching exact X–four-edge joint domains with decimal multiscale (DMSD) blocks and sound pruning, with conjectures X4-C1…C4, controls A–E and baselines; it proves nothing about existence.
A foundational methodology (a framework); it proves neither existence nor nonexistence.
DMSD here is a derived use of the 'decimal multiscale serializable domain' of the DMSD case on this site; the two folders have no byte-identical file, and the X4-DMSD line is a derived side-branch. P1–P13 of X4-DMSD are software and bounded computations (see the result page and the table below). No author line.
