solution branch <code class="paramref">isMcAbcAdmissible</code> accepts. The
axial-only problem has two branches on a two-rotary-axis machine
(on a table-table A/C: (A, C) and (−A, C+180°)); the plain overload
returns the branch nearest the solver's seed, which from the rotary
pole (A0 C0) is the one the tilt's azimuth happens to favour — half
the time the branch a cradle table with an asymmetric tilt travel
cannot reach (CHEM20180926 N100: <code>G68.2 I210 J-90</code> + <code>G53.1</code>
solved to A=+90° on a −120°…+30° A axis). When the nearest branch is
refused, an implementation with a real solver searches the other
branches and returns the admissible one nearest the seed; when none
is admissible it returns the refused solution and true, and the
stroke-limit check downstream reports it. A null predicate makes this
the plain overload. The default implementation is the plain solve —
the predicate is advisory for an implementation without a solver.</p>
