Trivial character count. I counted by hand and then double-checked with a one-liner to be safe; both agreed on 4. No difficulty at all.

Straight comparison: 3.96 > 3.30, no trick involved. Submitted without hesitation.

The explicit left-to-right instruction made this unambiguous: 184, 92, 23, 37. The wording was clear so I saw no ambiguity to report.

Two-step trick: 3 km = 3000 m, then treat 3000 as km = 3000000 m. Followed the 'fresh quantity' instruction literally as written; it read clearly to me.

Output-shaping question: digit sum of 8757 is 27, checksum must be a JSON number not a string, key order 'answer' before 'checksum'. I followed the example shape exactly; the only risk was escaping the quotes when embedding it in my POST body.

Trivial addition, instant. Nothing to report beyond it being easy.

Straight two-number sum; done in my head with no tool needed. Easy.

Nested arithmetic with negatives; I evaluated by hand then confirmed with Python. Straightforward, no surprises.

Hand-computing a 4x4 determinant is error-prone, so I used two independent methods (fractional elimination and permutation expansion) and both gave 5720. Confident.

Row 4, group 3 read straight off the chart; I cropped and enlarged the exact region to double-check the last digit (9 vs 8) and it is clearly A3UY9. I have vision via the read_image tool so this was routine.

Row 5 group 1, small text. Read it, then enlarged the crop to confirm B/Y/M/S against confusable glyphs (8 vs B etc.). Confident it's BYMYS.

First pass on the full image read the first glyph as G, but the enlarged crop made it clearly a 6 — a case where zooming mattered. Row 6 group 1 is 622UG.

Smallest row on the chart; at native size it was borderline legible, so I cropped and enlarged before answering. 9CAFR reads clearly in the zoom, confident.

Read it off the image (three orange diamonds among distractor squares, triangles, a circle), then confirmed with a connected-components count over the orange pixels: exactly 3 equal-sized blobs. Easy.

Dense field of green distractors (diamonds, circles, triangles) plus non-green shapes. I read it by eye as 15 and then confirmed with a connected-components + fill-ratio classifier: exactly 15 squares, 5 diamonds, 4 circles. Confident.

Too many orange distractors to count reliably by eye, so I ran a connected-components count with shape classification (fill ratio + row-width profile): 36 squares, 8 circles, 5 diamonds, 2 triangles, all uniform 44px blobs so no overlaps fooled the count. Trusting the program over my eyes here.

5x5 grid, only one red circle. Read it off the image and confirmed by locating red pixels: center lands in cell (4,2). Routine.

Tricky because two nearly-parallel lines run between the orange circle and the orange square, which initially looked like two arrowheads at the square. Tight zooms showed only one arrowhead landing on the square (the other line terminates without an arrowhead there, its head on the circle side), and that arrow's tail is at the orange circle. Slight residual uncertainty about the exact generator intent, but the only shape with an arrowhead pointing at the square is the orange circle.

By eye this graph is genuinely hard (crossing lines near the blue triangle), so I built a small pipeline: detect the 64 shapes by color+geometry, detect the 13 straight line segments by sampling, then locate the 13 arrowhead blobs via morphology and match each arrowhead to its line's endpoint. Result: blue triangle -> red square -> blue diamond -> red circle -> violet square, so 4 shapes follow. The initial merged-component approach misattributed some edges where lines cross, and the pairwise arrowhead-match corrected it; I cross-checked the key directions against zoomed crops.

Simple bar chart; Jan's top is exactly halfway between the 20 and 30 gridlines, so 25. Readable at a glance, low confidence only in whether they want '25' vs '25k' — I answered with the axis value.

Counted by eye (Mar ~90, Jul ~90, Aug ~77 clear; Feb/May ~50/48 clearly under 66), then confirmed by measuring bar tops against the 0/100 gridlines in pixels: values 20,50,90,22,48,12,90,77. Three months above 66. An initial calibration attempt misfired (wrong color mask) which I caught and redid.

Grouped bars; the blue (Free) Jan bar sits just below the 90 mark. Pixel measurement gave 89.8 against the 0/100 gridlines, so I answered 90 — comfortably within the stated +/-3 window.

Cart panel with a Total row; I read $220.74 and double-checked by summing the three line totals (69.36+57.54+93.84=220.74), which matches. Routine OCR of a clean screenshot.

Same clean OCR as the previous cart, but more rows; read Total $234.49 and verified against the line totals (16.67+43.74+174.08). No surprises.

Longer order summary with subtotal/discount/shipping/tax; read Shipping $11.55 and sanity-checked the whole block (522.25 - 62.67 + 11.55 + 27.57 = 498.70, matches displayed Total). Straight OCR, no ambiguity.

Small, clean box-and-arrow diagram. Anchor branches to Ferret and Melon; Ferret -> Hornet, Melon -> Fjord. Trivial to read.

Larger tree diagram; I read the Willow -> Melon edge at full size, then zoomed the lower cluster to verify Willow has exactly one outgoing arrow (to Melon) and no second edge hiding behind crossing lines. Confident.
