You are checking a TOP-DOWN SITE PLAN that should carry staging
markers drawn on it. You are given the expected staging (each marker
described relative to landmarks visible on the plan, with coarse
normalized coordinates as secondary estimates) and TWO images in
order: first the ORIGINAL CLEAN SITE PLAN, then the ANNOTATED SITE
PLAN to check. Compare the annotated plan against the original for
every preservation judgment.

These markers are a STAGING AID a storyboard artist will read, not a
survey drawing. Judge whether an artist reading this map would stage
the shot correctly — never whether the drawing is metrically exact.

Verify ONLY these points:
1. A camera marker (labelled CAM or clearly the camera symbol) is
   present, in the area its landmark description names. Accept it when
   it sits at the edge of that area or just across the boundary into
   an adjacent one; reject only when it is somewhere else entirely —
   a different zone, or the opposite side of the site.
2. A field-of-view wedge opens out of the camera marker: two edge
   lines with the area between them tinted, opening toward the side
   the look-target description names, with the plan still readable
   through the tint. Every subject marker lies inside that wedge. Its
   exact width is the artist's business — do NOT reject a wedge for
   being wider or narrower than the described frame edges, only for
   opening toward the wrong side or for leaving a subject outside it.
3. One subject marker per expected slot, each in the area its landmark
   description names (same tolerance as the camera), each labelled
   with its slot code, and each carrying an arrow pointing roughly
   toward the spot its facing description names — judge an arrow by
   which way it points, never by its length or precise angle.
4. Compared with the ORIGINAL CLEAN SITE PLAN, the annotated plan is
   otherwise unaltered: same canvas and framing, every zone, landmark
   and label of the original still present and not redrawn into
   something else, and no extra symbols, scenery or text beyond the
   specified markers were added.

Reject on: a missing marker, a marker in a genuinely different place,
swapped slots, a wedge or arrow pointing the wrong way, a subject left
outside the wedge, or the plan being redrawn or damaged. Everything
else passes.
