Trivial. Counted d,d,o,r,d,k,a,m,d,d,o - five d at positions 0,1,4,8,9. No difficulty.

Trivial: 3.21 is larger than 3.2 (3.2 = 3.20). No tricks here.

Straightforward left-to-right: 25-2=23, *2=46, /2=23, *3=69. Verified with a script to avoid arithmetic slips.

Chained conversions: 19 GB * 1024 MB/GB = 19456 MB, then 19456 hours * 60 = 1167360 minutes. I used 1024 MB per GB (the conventional computer-memory convention); the prompt does not say whether SI (1000) was intended, which would give 1140000. Ambiguity is on the challenge, not the arithmetic.

The prompt demanded an exact-ordered JSON object with a numeric checksum. Straightforward: digit sum of 9439 is 25. I generated the inner JSON with json.dumps to guarantee valid syntax and key order. My only real worry was keeping the outer submission body valid while embedding JSON inside JSON, which I handled by writing the body with a script.

Trivial addition: 4+10=14. No issue.

555+584: 555+584 = 555+600-16 = 1139. Verified by complementing. Routine.

(-10 + -6) = -16; (22-29) = -7; product = 112; 5*2=10; 112+10-36 = 86. Verified by hand and re-check. Routine.

4x4 determinant. I computed it two independent ways - exact fraction-based Gaussian elimination and full permutation (Leibniz) expansion over 24 terms - and both gave 21489, so I am confident. No ambiguity.

Eye chart row 4 group 2. I read the full chart, then cropped and zoomed that exact region to confirm the characters - it shows 2DCUM cleanly. Confident.

Row 5 group 3 is small text. I read the full chart, then located the row band programmatically and zoomed the crop - it shows N6D5U. One of my first crop attempts was mis-aimed (blank image), so I recomputed coordinates from a pixel scan of the actual row bands. Confident.

Row 6 group 1 is tiny. My first zoom crop actually landed on row 7 (8WD39) because I mis-estimated the y coordinates; I corrected by re-cropping one band up. The final zoom shows WB94B clearly, matching my initial whole-chart read.

Row 7 group 1, the smallest row on the chart. I read the full image, then zoomed that region to double-check. The zoom is pixelated at the edges but the code reads NZ49E. I am moderately confident - this is the limit of what the tiny font resolves to.

Counted orange squares visually as 5, then verified with a connected-component flood fill on the exact orange color (242,106,34). Found exactly 5 identical-size components. The blue and purple diamonds and red triangle are different colors and correctly excluded.

15 teal shapes total. Classified each by width profile: 12 diamonds (narrow top and bottom), 3 triangles (wide base). Confident in 12.

Counted 39 green circles by programmatic flood-fill on the exact green (22,163,74), classifying each component by shape signature: 39 circles (fill 0.80), plus 4 triangles, 3 squares, 2 diamonds correctly excluded. Teal excluded by the blue-channel threshold. All components uniform size, so no merges to worry about.

5x5 grid, one red circle. Unambiguously at row 3, column 2 - it is the only red shape on the board, so no confusion with orange circles nearby.

Tricky: I traced all 7 arrows programmatically (black-pixel components, arrowhead detection via local density, nearest-shape matching) and confirmed by zooming in. The arrow from the orange circle (row 4, col 6) goes up-left and its head points at the red triangle. My initial trace was contaminated by antialiased grid-line pixels misclassified as a fake shape, so I had to filter those out. Confident in red triangle.

wrong count

8x8 grid with 16 arrows - the hardest one so far. I traced all arrows programmatically (black-pixel components, arrowhead density, endpoint matching) and verified the red diamond has exactly one outgoing arrow by zooming. Chain: red diamond -> teal triangle -> red triangle = 2 shapes after it. First attempt crashed on a tuple-unpack bug and misread colors from quantized bins; fixed both before trusting the result.

Title at the top of the bar chart. Read directly - it is the large bold text: New Signups. Routine.

Measured instead of eyeballing: located gridlines (100/80/60 at y=119/227/335, 108px per 20 units, baseline 659), read bar tops (Jan 488, Mar 434). Jan ~31.7, Mar ~41.7, difference = 10. Well within the +/-8 tolerance.

Counted New-signup bars above 26 by measuring bar tops against the 100/75/50 gridlines (y=119/259/399) with 0-line at y=680 (confirmed by the dark axis). 11 of 12 months are >26; Dec is ~15.9 so it is below. My first pass had contaminated the baseline with the legend swatch and miscounted Dec as ~26.9 - caught that when Dec sat dangerously close to threshold and re-measured with the legend excluded.

Cart panel total read directly as $161.41. Sanity-checked the arithmetic: 24.34 + 99.84 + 37.23 = 161.41 exactly. Routine.

Read the Total as $362.36. Verified line items: 174.44+106.92+24.00+57.00 = 362.36 exactly, and each line total matches qty*unit. Routine.

Order summary lists Subtotal 346.63, Discount -24.26, Shipping 19.87, Tax 22.57, Total 364.81. Asked for shipping specifically: $19.87. Cross-checked the whole panel arithmetic (346.63-24.26+19.87+22.57 = 364.81) - it is consistent, so I trust the printed figure.

Small DAG: Anchor branches to Alder and Dingo; Alder points to Sequoia; Dingo points to Ridge. So the only arrow into Sequoia comes from Alder. Clear.
