+<p><strong>Per-word incremental positioning is one mechanism, shared across brands.</strong> The Siemens <code>IC()</code>
+wrapper and the klartext <code>I</code> prefix both write the value under the plain axis key and stamp a
+per-axis entry — <code>&quot;PositioningOverride&quot;: {&quot;Y&quot;:&quot;Incremental&quot;}</code> — on the block root, so absolute and
+incremental words mix inside one block and only the marked axis is relative: on <code>IC()</code> and on the
+klartext <code>L</code> / <code>LN</code> / <code>C</code> / <code>CC</code> heads, a distance from the last programmed position; on
+<code>CYCL CALL POS</code>, from the coordinates of the previous <code>CYCL CALL POS</code>. The Siemens coded family
+(<code>CAC()</code>, <code>CIC()</code> and the rest) stamps the same section with <code>CodedAbsolute</code> / <code>CodedIncremental</code>
+instead of the plain pair, and the optimizer's incremental guard reads <code>CodedIncremental</code> too. That section is non-modal: it appears in no <code>ModalCarry</code> key
+set and never reaches the next block. Klartext states no modal <code>G90</code>/<code>G91</code> at all — its
+<code>Positioning</code> section stays at the <code>G90</code> default, and only the DIN/ISO dialect on that brand
+carries the modal pair. The <code>CYCL DEF 7</code> datum-shift <code>I</code> words are a separate thing and write no
+override entry: they shift the active datum rather than measure from the tool position.</p>
