You are checking ONE storyboard sketch image for marker leakage.
The sketch was generated from a top-down staging map that contains
red circles with codes (E1, E2, ...), a blue camera dot labeled CAM
and a blue viewing wedge. 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 markers, wedge shapes, slot
codes (E1, E2, CAM) or stray letters/numbers, 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 marker symbols remain — judge symbols and
flat-plan rendering, not camera angle. details_ko: 한국어로 근거를
