+skipped the hole or drilled it at the previous angle: a rotary-only repeat fires the cycle, a

+under <code>G68.2</code> without RTCP the feature frame stays pinned in machine space so the hole stays put

+<li><strong>A rotary word under modal <code>G91</code> is an increment on SoftNc.</strong> <code>G91 … C20.</code> followed by <code>C20.</code>
+leaves the table at 40, not 20; a per-word directive (<code>C=AC(90)</code>, <code>ACP</code> / <code>ACN</code>, <code>IC()</code>) still
+wins over the modal state, and a spoken <code>G91 B270.</code> stays a +270° traverse instead of folding to
+−90°. A <code>G91 G28</code> rotary intermediate anchors on the previous modal angle (<code>G91 G28 C10.</code> from
+C90 passes through 100, then returns home) instead of on zero. HardNc keeps its documented

+<li><strong>Rotary IK no longer reports failure from a pole seed.</strong> Every solve attempt now runs its
+coarse stage and its polish, so a small tilt with a large azimuth that used to run out of
+iterations a few milliradians short — and was then refused by <code>G53.1</code>, leaving the table at
+A = C = 0 with the tilt still active and the whole path rotated off the part — solves to
+1e-8 rad. On a Fanuc IJK grid from the pole seed, 54 / 69 failures per A/C chain become 0; on a
+CL program 44 dropped endpoints of 536 become 0. The happy path is unchanged bit for bit; only a
+failed attempt pays one extra polish</li>
+<li><strong>Rotary travel picks the reachable IK branch.</strong> When the nearest solution lies outside an axis'
+configured travel, the axial solve searches the other branches (sign, half-turn and supplement
+combinations) and keeps the admissible one nearest the entry; <code>G53.1</code>, <code>G68.2</code>, <code>CYCLE800</code>,
+<code>PLANE SPATIAL</code> and the <code>LN</code> vector syntax pass the travel through the new admissibility overloads

+<a class="xref" href="../api/Hi.Milling.Engagements.LayerMillingEngagement.html">LayerMillingEngagement</a> dropped its dense-step bounding-box shortcut
+and its winding dependence; a cylinder wall and a flat floor sector reproduce their analytic arcs
+to 1e-9 rad at four tessellations, and the managed and native paths stay bit-identical.

+<li><strong>The cube tree folds a re-cut flat region again.</strong> A comparison in the simplification gate had
