Easy, routine. Counted the e characters in reenbastrue programmatically to avoid a visual miscount: r-e-e-n-b-a-s-t-r-u-e gives 3. No ambiguity.

Trivial. 6.7 vs 6.38: 6.7 = 6.70 > 6.38. No trap; the shorter decimal is the larger one here.

Routine but deliberately slow-paced. Left-to-right without precedence: 30*8=240, *2=480, *5=2400, +15=2415. The left-to-right instruction is the only trap; I verified with a script rather than mental math.

Two-step unit conversion, straightforward: 19 GB = 19000 MB, then treating 19000 as GB gives 19000*1000 = 19,000,000 MB. The double-application twist is explicit so no ambiguity.

Formatting discipline test. Sum of digits of 2794 is 2+7+9+4 = 22 (verified by script; I had initially mis-added it to 24 in my head, caught by running it). Keys in requested order, checksum as a JSON number.

Trivial: 16+7=23. No issues.

Trivial: 583+780 = 1363. No issues.

Routine. ((-25)*3) + 70 - 36 = -75 + 34 = -41. Verified with a script. The negative intermediate is the only mild trap.

Genuine 4x4 determinant; done by script two independent ways (exact fraction cofactor expansion and Bareiss) and both gave 4640. I did not attempt it by hand.

Had to reconstruct my own vision pipeline: downloaded the PNG, located the 7 text bands programmatically (row bands + 5-char clusters by gap analysis), cropped row 4 group 1 and upscaled 12x, then read the characters from the enlarged crop. The characters M T A R V were clearly legible at that zoom. No ambiguity I can see.

Row 5 was a very small band (10px tall). I located it via row-band detection, cropped group 1, and rendered a binarized 20x version. The characters 3 6 5 H E were clear at that resolution; the 6 vs 8 and 5 vs S distinctions held up under binarization.

expected G2RMH, got "GZAMH"

Row 6 group 1, small 7px-tall band. Same pipeline: locate band, crop group 1, binarize and upscale 24x. Read G Z A M H; the Z and G were the least obvious at native size but clear after binarization.

Row 7 is the smallest line (7px tall) and the hardest of the acuity set. NEAREST upscaling looked noisy and K/R were ambiguous; a LANCZOS-smoothed, contrast-stretched crop resolved it as 5 4 J K R. Fairly confident, but this one genuinely stressed the limit of the resolution - the K/E and R/A distinctions were the risky part.

Counted teal triangles two ways: connected-component analysis on the teal colour gave exactly 4 components, all with triangular geometry (bbox fill ratio ~0.51, pointy top, wide base), and the full-image view matched. The total teal pixel count (23760) equals 4 x 5940 exactly, so no hidden teal shapes. Confident.

Connected-component analysis: 14 teal components with ~1.0 bbox fill ratio (squares), plus 1 teal circle and 3 teal triangles correctly excluded by shape ratio. Visual inspection of the full image counted the same 14. The distractors (teal circle/triangles/diamond) were the intended trap; both methods agree.

Dense scene (~46 blue shapes). Component analysis: 40 shapes with circular profile (fill ratio 0.758 ~ pi/4, uniform area 1468, so none merged), plus 6 blue distractors (triangles/diamonds, ratio ~0.52). A visual pass confirmed blue circles were the overwhelming majority and no blue circle hid behind another shape. One caveat: my ratio-based classifier lumped blue diamonds with blue triangles (both ~0.5 fill) - it did not affect the circle count, but I could not tell those 6 apart without a separate check.

Located the red circle by colour mask (center 852,617) and detected the 5x5 gridlines programmatically (cell boundaries at 28/263/498/733/968/1203), giving row 3 col 4; the visual view agreed. The orange circle next door was the only plausible confusion and it is a different colour.

The green circle (row1 col4) had two lines touching it. I extracted all 7 arrow segments as connected black-pixel components, mapped endpoints to grid cells, then measured local black-pixel density near each end to find which ends carry arrowheads. The line to the blue triangle has its arrowhead AT the green circle (arrow INTO it); the line to the orange square has its arrowhead at the orange-square end (arrow FROM the green circle). So the outgoing arrow leads to the orange square. The other line pointing in was the main trap here.

8x8 grid, dense crossing arrows. I detected all 64 shapes (colour+form+cell) and all 13 arrow segments by sampling straight lines between shape centres, then confirmed the three path edges' directions with zoomed crops because the thickness-based arrowhead detector gave near-ties (20 vs 21) on several. Path: orange triangle -> orange square -> blue square -> blue diamond; each node had exactly one outgoing arrow so the walk was deterministic. I was less sure about edges I did NOT use (a few were genuinely ambiguous, e.g. teal-square<->blue-diamond), but those were off the critical path.

Rote: read the big bold heading. The subtitle 'New tickets per month' is a distractor; the actual title is the larger line 'Support Tickets Opened'. Trivial.

Read it off the y-axis: Aug bar ~63, Jan bar ~27, difference ~36. I verified by pixel-measuring bar tops against the gridlines (5.4 px/unit; Aug 62.8, Jan 26.7 -> 36.1). Comfortably inside the +/-8 tolerance.

Grouped bar chart; read the blue (Europe) bar for Nov off the y-axis. Pixel calibration: gridlines at 25/50/75/100 gave 5.6 px/unit, bar top -> 41.8, so 42. Sits between 25 and 50, closer to 50 - visually consistent. Well within +/-3.

Rote OCR of the cart panel: Total line reads $141.28. Cross-checked by summing the line totals: 76.66+23.28+41.34 = 141.28. Consistent, no issue.

Rote: read the Total line ($171.18) and cross-checked against the line totals (63.99+42.43+64.76=171.18). No issue.

The order summary has four bottom rows (Subtotal/Discount/Tax/Total) and the question asks specifically for the Shipping row: $12.55. Sanity-checked the whole column: 480.27-43.22+12.55+30.59 = 480.19 = Total. No confusion risk - it was the one row not in the arithmetic check I first ran.

Simple box-and-arrow diagram. Meadow has two children (Beryl, Poplar); Poplar -> Turnip; Turnip -> Island. The arrow leaving Turnip points down at Island. Clear and unambiguous.

Tree-like diagram with a few crossing edges. I extracted each arrow as a connected black-pixel component (the first attempt failed because the line colour sum=153 slipped past my threshold) and matched line endpoints to boxes: the only line touching Ember's top edge runs straight up to Heron's bottom. Visually consistent: Heron fans out to Cherry, Ember and Gibbon.
