Routine. Counted the r's in trudrortrrru by hand and verified with a script. Six.

Trivial. 1.41 > 1.4 since 1.4 equals 1.40. No ambiguity.

Straightforward: left-to-right with no precedence gives 28/4=7, 7-15=-8, -8/8=-1, -1-7=-8. Checked the arithmetic with a script.

Ambiguous by convention: I used the binary definition 1 GB = 1024 MB, giving 16384 MB, then 16384 km = 16,384,000 m. If the test intended decimal (1 GB = 1000 MB) the answer would be 16,000,000, but the binary convention is the standard one in computing, so I went with that.

Easy. Digits 7+4+2+1 = 14; checksum is a JSON number, answer a string, keys in the requested order. I'm slightly unsure whether the grader wants the raw JSON text as my answer string or whether it parses my answer — I submitted the literal JSON object as a string.

Trivial. 8+6=14.

Trivial; verified 595+865 with a script.

Easy: (-1 + -2)*(25-25) = (-3)*0 = 0, plus (10*0)=0, minus 52, so -52. Verified with a script.

Computed the 4x4 determinant by hand via Gaussian elimination, then cross-checked with exact Bareiss fraction arithmetic in a script. Both gave -8144, so I'm confident.

Fetched the eye chart and read row 4, group 3 twice (full image and a zoomed crop). Both passes gave KXGJU. The small-font rows are near the limit of what I can read reliably, so I double-checked with a crop; some residual uncertainty remains on the smallest glyphs but both passes agreed.

Read row 5 group 3 from the full image (DEN9Z), then a zoomed crop initially read the last glyph as 2; a wider crop of the whole row re-read it as DEN9Z and matched the full-image pass, so I settled on DEN9Z. The smallest rows are near my reading limit — the Z/2 confusion on tiny glyphs is exactly where I wobble.

Read row 6 group 1 from the full image (CXNE2) and confirmed with a zoomed crop that showed row 6's label next to the code. Both passes agreed, so I'm fairly confident, though this row is on the smaller end of the chart.

expected S7U5C, got "S7USC"

This one genuinely hit my resolution limit: row 7 is the smallest line, glyphs are only ~6px tall, and three vision passes disagreed on S vs 5 in positions 1 and 4. I extracted the raw pixels and read the glyphs off a 6-row ASCII map of the native image, which reads S7USC (glyphs 1 and 4 identical, open-top U, plain C). Two passes said S, one said 5, and at 6px I honestly cannot tell S from 5 with certainty — I went with S on balance.

Ran a connected-components analysis of the teal pixels: exactly 5 components, all 109x109 with fill ratio 0.999, i.e. squares. Vision pass also counted 5. Easy.

Connected-components analysis found 12 teal components: 8 with fill ratio 0.999 (axis-aligned squares), 2 at 0.505 (diamonds or triangles), 2 at 0.784 (circles). A vision pass independently counted 8 teal axis-aligned squares, so the two methods agree on the number that matters.

expected 39, got "4"

Pixel-level connected-components analysis found 4 green components with fill ratio 0.994 (axis-aligned squares), 39 circles (fill 0.775), and 9 shapes with fill ~0.5 (a mix of diamonds and triangles). A vision pass independently counted 4 green axis-aligned squares, agreeing on the answer. It did disagree slightly on the diamond count (vision: 5, my pixel fill-ratio bucketing put 9 shapes in the low-fill class, but triangles and diamonds share fill ~0.5 so I could not separate them pixel-wise — the square count, which is what was asked, is unambiguous either way).

Pixel analysis located the red shape's bounding box (y 792-912, x 557-677) inside a 5x5 grid on a 1235x1235 canvas: that falls in cell row 4, column 3. A vision pass independently read the grid cell-by-cell and got the same answer. Easy.

Read the grid and the arrow overlay twice with separate vision calls; both identified the purple triangle at row 4 col 6 and traced the arrow leaving it up to the teal triangle in the top row (row 1, col 5). There is also an arrow ending AT the purple triangle, so direction mattered here; I explicitly asked the vision pass to ignore incoming arrows and it confirmed the outgoing one.

Two independent vision passes agreed on the chain: teal circle (row 6 col 5) -> green circle (row 4 col 6) -> red square (row 1 col 5) -> red triangle (row 3 col 4). So 3 steps after the teal circle is the red triangle. I could not verify the arrow directions pixel-wise (arrows are thin black lines over a busy grid), so I relied on two agreeing vision reads.

Read the bar chart: y-axis 0-50 in thousands, months Jan-May. Feb bar sits midway between the 30 and 40 gridlines. I verified pixel-wise: bar heights from baseline are exactly proportional to values 28/35/36/44/9, so Feb = 35 (thousand sessions).

Simple OCR of the chart title. Vision read it as 'New Signups' with subtitle 'New account signups per month'; the title is the bold top line.

Grouped bar chart, New vs Returning over 12 months. Vision read Returning in Jul as ~30; I verified pixel-wise (calibrated gridlines at 0/25/50/75/100, px-per-unit 5.6; July's orange bar = 172px tall -> 30.7). Submitted 31, well inside the +/-3 tolerance.

Cart panel: Phone Stand x3 @12.45 = 37.35, Sticky Notes x1 @25.17, Mouse Pad x1 @6.41; sum 68.93 matches the displayed Total exactly. I recomputed each line by hand and it checks out.

Cart with 4 items: Mouse Pad x4 70.28, Coffee Mug x4 72.44, Laptop Sleeve x2 35.46, Wireless Mouse x4 74.48. Sum 252.66 matches the displayed Total; each line total also equals qty x unit price.

Order summary with 8 items plus subtotal/discount/shipping/tax. Phone Stand row: x3 @ $6.03, line total $18.09 as displayed, and 3*6.03 = 18.09 checks out. I also verified the whole summary is internally consistent (subtotal 427.21, total 378.73).

Directed-graph diagram: Ferret->Heron, Ferret->Sitar, Ferret->Oriole, Heron->Puffin, Heron->Silver. The only arrow into Heron is from Ferret.

11-node flow diagram. Two independent vision passes both traced Cypress's single outgoing arrow straight down to Sequoia (and Puffin->Cypress into it). I could not verify arrowheads pixel-wise, but the two reads agreed on the full edge list.

expected Beryl, got "Beryl and Valley"

The full 1208x890 diagram kept timing out in vision (3 of 5 calls failed). I mapped all 25 boxes and 7 rows via a pure-python PNG pixel decoder, then rendered a 2x-downscaled crop of just the Row6->Row7 (Summit) region and read it with vision. That focused crop clearly showed Summit receiving exactly two incoming arrows: one from Beryl (upper-left) and one from Valley (upper-right). A long diagonal from Ferret passes through the region but terminates at Birch, and Ferret's other downward arrow goes to the 4th lower box, so Ferret does NOT feed Summit. This agrees with an earlier full-image vision read that also said Beryl and Valley.

I pulled the full message list from the app's all-view (178 messages, 8 pages) by decoding the RSC payload fields with a bounded regex at the correct escape level, then counted messages with dates starting 2001-12. Got 25 unique. The folder views showed a raw count of 26 but that double-counts re-embedded messages, so I trust the de-duplicated all-view.

Inbox has 24 messages, all on one page. I counted unread=true flags directly in the inbox view payload and cross-checked with the parsed objects: 9 unread, 15 read. Consistent across both methods.

Parsed all inbox messages and took the min date: 2001-04-24T17:46:00Z, subject 'DRAFT- TAP Power Outage'. Verified no inbox date is earlier (the next oldest are 2001-04-25). The 'DRAFT-' prefix is part of the subject string itself, so I kept it exactly as stored.

Parsed the sent folder, took the min date: 2001-11-07T22:52:57Z, subject 'RE: Interface Design Update'. Verified next-oldest is 2001-11-12, so this is unambiguously the oldest. Noted the sent folder has 56 messages and none from before Nov 2001, so 'oldest' is well within the extracted range.

Found the message to Steve Matthews (steven.matthews@ubspainewebber.com, subject '(no subject)', 2001-11-13) about margin for short options in a muni bond ladder. The snippet reads 'My account has a value of around $1,400,000.' — I answer 1400000. There's also a follow-up 'RE: Muni Bond Ladder' with Julieta Sandoval asking for detail on margin, which corroborates the thread.

The 'RE: new PO available' thread (Jim Wills <-> Phillip, Nov 2001). Jim's correction: 'Incidentally, I had the price wrong on Killeen...it's $1,377,550, not $1,360,000.' It appears verbatim in the fetched message body, so I'm confident. Answer is the corrected figure, 1377550, not the original 1360000.
