{"n":1,"what":"atlas v1: one standing profile from the construction kit","saw":"reads as a dog; neck long, head high (giraffe risk), collar band odd","change":"lowered head, deeper chest, ring rebuilt as a band across the neck"}
{"n":2,"what":"atlas v2: 40 drawings (stand, gait charts for walk and backing, turn views, lying, refusal flops, look-in)","saw":"walk head reads low but ears stood above the back line; front view looked like a hippo / helmet; look-in back-of-head was a ball with a floating sliver; q45_up and rise_R had giraffe necks","change":"new low ear set for the approach, head bases lowered; front view rebuilt with the head three-quarter (leading the turn); head_back redrawn as a true back-of-head with both ears and a cheek sliver"}
{"n":3,"what":"person bank (stand, call, reach, steps, sit, low hand, soft voice)","saw":"low hand was at shoulder height","change":"lean forward and arm angled down; person walk set on its own gait chart (6 drawings) after seeing 0.3 m slides with two step drawings"}
{"n":4,"what":"first Viterbi path","saw":"sensible order (watch, backing cycle, wary, q45, f90, q135, cower_R, lie_R, rest_R, lookback_R at 7.458, rise, turn, watch, walk, sit, lie, look_in with wag alternation, rest). Fault: back_6 -> walk_6 at 2.6 s (65 px paw slip)","change":"hard transition penalty between backing and walking groups; held drawings keep their spot; feet-matched placement when a gait run ends; slip metric split into slide (while held/in cycle) and step pop (redrawn paw)"}
{"n":5,"what":"first stills in the staged world (front elevation porch, door hinged right, room beyond)","saw":"composition works; sill stone too bright; black hole beyond the porch end; dog washed out by door light at the sill","change":"stone darkened, yard drawn beyond the porch, warm light on figures reduced"}
{"n":6,"what":"turn contact sheets 3.42-4.0 and 7.33-8.67","saw":"front view still box-like with a cream stripe across the back; return turn reads (head over shoulder at 7.458, rise, front with head to door, three-quarter, watch); cast shadows muddy","change":"front view: smaller back hump, ring moved under the head, thicker legs; shadow blurred and lighter"}
{"n":7,"what":"curator clusters vs bank","saw":"two unexplained clusters: rising at 7.6 s (distance 1.98, nearest rise_R) and the refusal lie (1.07)","change":"new artwork situp_R (half up, back still to the door, looking round); refusal lying drawings labelled crouch .5 (they are drawn curled, tail tucked). Rising cluster distance fell to 0.93"}
{"n":8,"what":"measured onsets","saw":"retreat and approach centroid onsets +0.25/+0.54 s because the walk segments were offset to match the previous paws","change":"walks start at the score's own position (first drawing takes the first step); retreat and approach now move on screen at +0.083 s"}
{"n":9,"what":"full render + sound + check","saw":"912 frames, 38.0 s, 3.3 MB; check_handmade ALL OK; title overflowed; end-card thumbnails piled up; dog too dark mid-approach in front of the wall","change":"title 54 px; end-card thumbnails evenly spaced with leader lines to their frames; dusk tint on the dog halved; end-card claim about person/door made exact"}
{"n":10,"what":"final rebuild via build/make.sh","saw":"check ALL OK (I1 dts .083/.042/.041/0/.084/.083, I2 end 0.59, I3 r .999, I4 .958); soft voice 11-13 dB below calls and ~24 dB above room tone, measured on the AAC; frames looked at again","change":"stopped here"}
