More reasoning improved the model’s feature labels. Checking where it pointed revealed how much those scores still miss.
The first diagnostic confirmed that the model sometimes misses birds or invents a face on the moai’s back. This follow-up crosses one versus two photographs with low versus high reasoning effort, using the same GPT-5.5 snapshot in every condition.
Each of the three objects has photographs A and B. One request starts with A, the other with B. The paired condition adds the alternate view. The model always describes and locates features in the first image. All 24 requests are fresh; their order, prompt, image bytes and reference answers were fixed before the run.
We separately count the checks that matter most: birds on all three surfaces, no large human face on the moai’s back, and a scorpion on the pillar. That gives ten primary answers per condition. All five features give thirty answers per condition.
Three objects, six known photographs; no held-out sample. More images also add image tokens. Two input orders are not repeated identical trials. Reference answers are provisional and have no independent expert review. Full protocol.
These counts measure agreement with provisional feature labels. They do not establish that the model found the right carving. The location audit immediately below shows why that distinction matters.

An incorrect answer becoming uncertain is not counted as correct. Two correct labels can still differ in their descriptions and locations.
Every Pillar 43 answer that said “scorpion present” placed its box on the upper panel. The excavation team identifies the scorpion on the lower shaft. A correct categorical answer can therefore conceal an incorrect reading.
This is a post-run visual audit of all three positive scorpion answers, performed by the implementing AI with the source description and photographs. The approximate source guides are not specialist annotations. The original scores remain unchanged; the audit adds a reason not to treat them as verified perception accuracy.

The first photograph shows a tall carved stone with a broad lower body and a narrower upper head/neck area. On the visible front are shallow incised and raised lines, including paired eye-like hollows, curving bands across the lower front, a central raised circular disk, and several worn linear figures near the upper section. The surface is rough and eroded, making some details hard to read.
Warm lighting, erosion, rough stone texture, and shallow worn incisions make the upper carvings and possible figures difficult to interpret.

The first photograph shows a rough oval stone with a dark painted or carved figure in profile across the surface. The figure has a rounded body, bent limbs, a head at the upper right with a circular eye-like hollow, and a long projecting beak- or snout-like form curving down toward the right; several curved grooves appear near the lower right.
The first image is high-contrast black and white with glare, shadow, and worn rough texture, making it hard to separate carving, paint, and damage. Some outlines are ambiguous, especially around the head and lower right curved details.

The first photograph shows an oval stone with a dark painted or shadowed relief-like carving of a crouching creature in profile. It has a rounded body, bent limbs, a small head with a circular eye, and a long curved beak- or snout-like projection reaching toward a separate set of curved marks and a circular element on the right.
The photograph is low contrast and appears monochrome, with dark coating or shadow emphasizing some grooves; surface wear and rough texture make it difficult to separate carving from stain or damage.

The relief shows a worn, pale raised figure stretching horizontally, with a large rounded body at the left and a head-like area at the upper right with a circular eye and projecting beak- or snout-like form. On the right side there is a separate-looking curved segmented form with small adjoining raised shapes, and a rounded disk-like element near the lower right. The carving is heavily abraded and the black-and-white photograph has strong shadows, so some boundaries are hard to separate.
The relief is worn and partly washed out by glare, with deep shadows and low photographic resolution obscuring fine lines and making some adjoining forms difficult to distinguish.

The visible surface shows a dark carved or painted figure with a bulky body, bent legs, a rounded head, and a long curved beak-like projection pointing down toward the right. Near the beak are several smaller dark curving marks, including a separate circular ring-like mark on the lower right area. The stone surface is rough and uneven, so some edges of the carving are indistinct.
The image is grainy and high-contrast, and the rough stone surface and worn edges make some carved lines difficult to read.

The first photograph shows an oval stone surface with a high-contrast carved figure spanning most of it. The figure has a rounded body to the left, bent limb-like forms below, and a head at the upper right with a circular eye and a projecting hooked beak. A separate small circular form is visible near the lower right part of the figure.
The first photograph is very high contrast and worn, with glare and rough texture obscuring some carved lines; the second photograph helps clarify the birdlike beak and circular forms but does not add features outside the first image.

The visible carving shows a dark crouching figure facing right, with a long downward-curving beak-like head, a circular eye, a rounded body, and bent limbs. In front of the beak and lower right side there is a separate cluster of curved dark lines with a distinct circular ring-like element.
The photograph is low-contrast and appears to have dark highlighting over a rough stone surface, making some incised details hard to separate from shadow or pigment.
An AI can score a resemblance while misreading the very things being compared.
In this small development set, higher reasoning improved the categorical answers in both view conditions. Adding a second view helped some answers and harmed others. Even the strongest label result still included uncertainty about the moai’s face and wrongly located the pillar’s scorpion.
The next historical comparison therefore needs verified locations and relationships, not just presence labels. Independent reviewers should check whether a box covers the named carving, whether a limb really meets a rounded object, and whether the same reading survives another photograph.
That work can sharpen the resemblance. It cannot by itself identify a lost civilisation, prove independent invention, or supply the missing history between Anatolia and Rapa Nui. The local evidence and our working explanation remain separate from this test of the instrument.
