What are the 5 fingerprint traits of a character's voice?
Per character, lock: 1) average sentence length (terse vs flowing), 2) vocabulary register (street vs academic), 3) signature idioms (3-5 phrases unique to them), 4) profanity level, 5) hedge words ('maybe', 'I guess'). These five make a character recognizable in a one-line tag. In PlotWrite, put them on the character's Story brain page so they sit next to the rest of what you know about that person.
Why does character voice drift over a long serial?
Over months of writing, your own defaults bleed in. Without a written fingerprint, character A starts sounding like character B a few chapters later. If you draft with AI, its defaults bleed in even faster. PlotWrite's Style DNA keeps your POV, tense, rules and avoid list in one place, and on the Architect plan Hard lock makes every AI output follow your learned voice. Drafting with AI is optional, and pasting AI-written prose into a chapter means Royal Road asks for an AI tag.
How do you test whether a voice is distinct?
Use the dialog-tag test: read every dialog line out of context. Can you identify the speaker without the tag? If no, your fingerprints are too weak. Strengthen them.

How often should you check voice consistency?
Run a voice consistency scan every 20 chapters. Identify any character whose fingerprint has drifted. Re-lock and continue. The Soul check in Craft helps with the emotional side of a chapter, and your Story brain page is the reference you scan against.
