+"""CJK/wide-character-aware re-alignment of model-emitted markdown tables.
+
+Models pad markdown tables assuming each character occupies one terminal
+cell. CJK glyphs and most emoji render as two cells, so the model's
+spacing collapses into drift the moment a table reaches a real terminal —
+header pipes line up, every body row drifts right by N cells per CJK
+char.
+
+This module rebuilds row padding using ``wcwidth.wcswidth`` (display
+columns), preserving the table's pipes and dashes so it still reads as a
+plain-text table in ``strip`` / unrendered display modes. Standard Rich
+markdown rendering already aligns CJK correctly inside a wide enough
+panel; this helper is for the paths that print the model's text more or
+less verbatim.
+
+The helper is deliberately conservative:
+
+* Only contiguous ``| ... |`` blocks with a divider line are rewritten.
+* Anything that does not look like a table is passed through unchanged.
+* Single-line / mid-stream fragments are left alone — callers buffer
+  table rows and flush them once the block is complete.
+
+There is a small, intentional caveat: ``wcwidth`` returns ``-1`` for some
+emoji-with-variation-selector sequences (e.g. ``⚠️``); we clamp those to
+0 so they do not corrupt the column width math. The 1-cell drift on
+those specific glyphs is preferable to silently widening every table
+that contains one.
