What Does Canon Compliant Mean?
Fic TypeA fic that fits within canon without contradicting it — filling gaps, expanding scenes, or exploring time the source material skipped. Everything canon says happened still happens.
Canon Compliant in Practice
Canon compliance is a craft constraint that many writers find generative: the story must thread through established events, slotting missing scenes, off-screen conversations, and pre-canon or post-canon stretches into the spaces the source left open. Readers who want fic that feels like it could have been deleted scenes filter for the tag specifically. Compliance has a shelf life, though — a fic perfectly compliant when posted can be 'jossed' by the next season, which is why authors often note 'compliant through episode X.' The tag frequently appears alongside missing-scene and episode-tag works, and it contrasts directly with canon divergence.
Example usage
"This is canon compliant through season three, which is exactly where I also stopped acknowledging the show."
