{"n":1,"what":"studied the kit: contact sheets of archive-dog frames + SAM masks and archive-door frames + masks; dog pose keys (frame 8 profile, 19-23 head low); door-leaf mask widths per frame","saw":"SAM dog masks are crude blobs (good for proportion, useless as a cut outline); the left door leaf closes from 67 px to 130 px over frames 18-31, a clean swing to reverse","files":["study/archive-dog-sheet.jpg","study/archive-door-sheet.jpg","study/dog-f8-keys.png"]}
{"n":2,"what":"first stage + puppets, 6 preview frames","saw":"the lace-border code zeroed every black card drawn before it (porch, roof, lantern gone); front legs braced forward like a frog (IK bend sign wrong for elbows); dog a barrel-chested jackal with giant ears","change":"border built in its own mask and unioned; elbow bend -1; dog recut"}
{"n":3,"what":"dog recut from measured proportions (spine 0.47 m, chest depth halved, shorter head, broader ears), design sheet of 12 poses","saw":"reads as a shepherd in profile; tail a stiff stick with saw-tooth notches; avert/over-shoulder head for a standing dog read as a blob","change":"tail tables lowered and smoothed; refusal head lead changed (see 7)"}

{"n":5,"what":"first full render (5.5 min, 912 frames) and frame strips of retreat and walk","saw":"retreat reads as backing away crouched; walk reads; a bump on the back at the spine pin","change":"round lap joint: both body pieces end in arcs centred on the pin"}

{"n":7,"what":"refusal head lead, three tries","saw":"(a) head swung back over the withers: blob; (b) end-on head from behind: read as headless; (c) end-on head facing the viewer, low, ears flattening outward: reads as averting the face","change":"kept (c); both body turns now pass through the front-view replacement (3D-consistent with (c)); the rear-view body is kept in code but not used"}
{"n":8,"what":"reach","saw":"the grasping hand ended on the black door casing and merged","change":"the reach became a lunge (lean 34 deg): the open hand clears the casing into the sky"}
