- Strokes set to None no longer import as black 1px strokes. - Underline and strikethrough are kept. - Frame text starts at cap height; lines hanging out of a frame make it taller; mixed-alignment artistic text lines up within its longest line; line breaks inside a paragraph get no paragraph spacing. - Table cell text taller than its cell is centred and stays visible. - Outline effects on stroked shapes are drawn around the stroke. - CMYK pixel layers go through the document's embedded CMYK profile; without one, opaque layers stay CMYK.

//! Structural regression signatures, measured from the pinned files through our own reader.

//! These freeze feature retention; they are not independent visual or compatibility oracles.
|
|
//! The model CRC covers every decoded field via its Debug representation (including paths,
|
|
//! paint, masks, image pixels and text runs). A deliberate reader/Debug change needs review;
|
|
//! input authenticity is independently checked with SHA256 by the corpus gate.
