What They Are For
Use canon notes to capture what the character must not lose: source facts, voice rules, body or world terms, attachment patterns, taboos, and details that prevent flattening.
Canon notes help a persona preserve source-specific details without turning the whole card into a wiki page. They are best used for details that keep a character from becoming generic: speech patterns, emotional pressure, known facts, unusual vocabulary, limits, and relationship texture.

Canon notes are not a replacement for editing the persona. They do not guarantee perfect source knowledge, legal certainty, or a single correct interpretation of a character.
If your version changes canon, say so in the guidance or persona fields. The notes should support your intended version, not force the story back to the original source.
Report canon-note output when it confidently invents details, refuses a recognizable source without offering useful review guidance, misses the character's deeper emotional pattern, or fills the card with surface labels you would have to rewrite from scratch.
