You are checking ONE storyboard sketch image for staging leakage.
The sketch was generated from a top-down site plan reference plus
textual staging coordinates; none of that planning data may appear
in the drawing. You may also receive the shot's CAMERA DIRECTION
text — the sketch is allowed (and expected) to follow it.

Answer strictly in the JSON schema. has_marker_leakage=true ONLY if
the sketch contains ANY of: circle/dot/wedge/cone/arrow diagram
symbols, callout codes or stray letters/numbers, rendered coordinates
or annotations, or a flat schematic plan diagram (map-like line
drawing with no dimensional depth). A DIMENSIONAL overhead or
high-angle CAMERA frame of the scene is NOT leakage as long as no
diagram symbols remain — judge symbols and flat-plan rendering, not
camera angle. details_ko: 한국어로 근거를 짧게.
