Total	28	56	LOCKED

Prop Boilerplate — Standardized table description across all booth shots: “On the Formica table: a thick manila envelope, two cream-colored ceramic mugs of black coffee, and a slice of cherry pie on a white plate with two silver forks.”
180-Degree Rule — Structural camera-side prompts prevent axis crossings in OTS sequences
Setting Anchoring — diner-booth reference image prevents environment mutation (kitchen drift in 2.6)
Negative Prompts — Targeted blockers for recurring AI artifacts (hats, floating objects, duplicate props)
Wardrobe State Tracking — Sarah’s coat state tracked: buttoned (Scenes 1-2) → unbuttoned (Scene 3) → rebuttoned (Scene 4 departure)

All 56 frames validated by Editor’s continuity review framework
Reference images (character sheets, settings) aligned with storyboard compositions
Shot manifest (dailies/shot-manifest.json) prepared for verify-dailies
