Coherence Guardian
The Coherence Guardian is StoryHelm's continuous continuity check: it reads your manuscript and series Canon to surface name, timeline, and trait contradictions before a reader ever finds them.

What it does
The scar on a minor character's left hand in Book One, the day of the week a battle was fought, whether the tavern sits two streets north or south of the harbor. These small facts pile up across hundreds of thousands of words, and the memory that wrote them is the same memory asked to keep them straight.
The Coherence Guardian is the part of StoryHelm that watches those facts for you. As your manuscript and Canon grow, it cross-references every new scene against everything it has already read and raises a flag the moment a detail stops agreeing with itself. Each flag names the two statements that collide.
It watches three kinds of drift in particular:
- Name & identity contradictions: a character introduced as Helen who is later called Hannah; a place spelled two ways; a faction that quietly changes its name between books.
- Timeline contradictions: events that happen out of order, a journey that takes three days in one chapter and overnight in the next, a character's age that doesn't add up against a stated birth year.
- Trait & established-fact contradictions: an eye color, a sworn vow, a magic rule, or a stated relationship set down one way early on and quietly changed later.
It runs as you write, and again across the series
Within a single manuscript, the Coherence Guardian checks each scene against the running Canon during analysis. At the series level, it widens its view through the Series Atlas, comparing Book Four against the shared continuity of Books One through Three so a fact established in your debut still holds in your finale. Every flag points to the exact chapters and the exact lines in conflict, so the fix is a decision, not a hunt.
The Coherence Guardian reads your manuscript and your Canon, finds where two facts disagree, and shows you both passages side by side. You stay the author of every word; it points out the contradiction and leaves the wording to you.
An example
Here is the kind of drift the Coherence Guardian is built to catch: a single character answering to two names across a four-book series. The two passages below are an illustration, not output from a real book.
The casebook walks the same example end to end: how the flag surfaces, the two passages in context, and the three ways an author might resolve it. Open the Helen / Hannah casebook →
