{"n": 1, "what": "read BRIEF, SCION 19 prompt, score, checker; looked at one still each from 37, 33, 25, 34", "saw": "37 textured 3D mesh, 33 wooden mannequin, 25 flat vector cut-out with gradients, 34 engraved line hatching; all dusk-blue", "changed": "chose a single variable-width ink contour over flat fills, on paper grain, with a cream/ochre dog; cutaway house section"}
{"n": 2, "what": "rig v1: bones, IK legs, capsule-mass vector mesh, 5 head switch drawings; 17 sampled frames", "saw": "reads as a dog; head small, neck and legs spindly (fox/greyhound); the far jamb strip covered the person in the doorway; at the end the dog's head landed on the seated person's shoe", "changed": "head drawn 1.22x, thicker neck/legs/chest; jamb drawn before the person; person moved further away"}
{"n": 3, "what": "turn frames 3.42-4.25 and 7.33-8.42 at 2-frame steps", "saw": "turn 1 frame 3.67: head hanging into the chest while the body is front-on, a lump; flattened ears drawn edge-on as sticks; eyes read as closed slits", "changed": "head held up (head >= 0.8) through the turn and dropped after 3.9; flattened ear tip moved and ear bulge widened; eyes bigger"}
{"n": 4, "what": "ending 24-30 s", "saw": "the look-in (three-quarter back head) pointed straight at the seated person's hand: it read as looking at the person, not into the room; the opened door leaf (100 deg) hid the lit room behind the dog's head", "changed": "restaged: the person steps out and sits on the porch, back to the house wall, beside the door; the door now swings 165 deg back against the inner wall, so the muzzle points into an open lit room, away from the person"}
{"n": 5, "what": "tests.js T2/T4", "saw": "lying hind feet spread in z broke 3D segment lengths (6 mm); stance feet slid up to 7 mm (a 0.92 scale on the stance offset, and fore legs over-reaching at the stride ends)", "changed": "legs keep one z plane; scale removed; stride 0.60 -> 0.46 m. Now max 3D length error 7e-16 m, stance slip <= 1.0 mm, no reversals"}
{"n": 6, "what": "first full film; frames extracted from film.mp4 through both turns", "saw": "every frame of both turns is a dog; head leads at 7.46 (back-of-head drawing 7.58, muzzle to the door 7.67 while lying); but at 8.27 the body in back view still showed the cream chest bib, so the rump read as a chest", "changed": "the bib is now a switch: drawn only while the chest front faces the camera"}
{"n": 7, "what": "stills from the film", "saw": "still_03.6 caught the front-view drawing mid-turn: the dog faces us in the refusal still", "changed": "turning away tightened to 3.40-3.64 (head) / 3.43-3.64 (body): five head drawings in six frames; by 3.6 the back is turned"}
{"n": 8, "what": "trace onsets from the render", "saw": "look-in head switch measured at 26.67 s, +0.27 against 26.4", "changed": "look-in eased 26.38-26.62; measured 26.54. Final film: 912 frames, 38.0 s, 4.5 MB, checker ALL OK; look-in and 3.6 s still re-checked on frames from film.mp4"}
