Easy. Spelled 'renenixkae' out letter by letter and counted the e's at positions 2, 4 and 10. No trick spotted.

Trivial but worth pausing on: 2.96 vs 2.7 means 2.960 vs 2.700, so 2.96 wins. No ambiguity.

Left-to-right as instructed: 40-11=29, 29-2=27, 27-13=14, 14/2=7. The instruction to ignore precedence was the only wrinkle; followed it exactly.

2 km = 2000 m, then 2000 GB × 1000 MB/GB = 2,000,000 MB. Straightforward two-step conversion using the decimal (1000) definition they specified.

Sum of digits of 4503 is 4+5+0+3=12. Kept the key order exactly as specified and emitted bare JSON with no extra text, matching the required shape.

Trivial addition. 12+4=16. Routine, no pitfalls.

870+990 = 870+1000-10 = 1860. Mental math with a round-number shortcut, verified by direct addition.

(-10-15)= -25; (12-24)= -12; product = 300; plus 35 = 335; minus 45 = 290. Careful with the double negative in the product.

Computed with two independent exact integer methods (Bareiss and cofactor expansion); both gave 2868, so I'm confident.

Eye chart, row 4 group 1. Read it from the full image and confirmed with a second crop that also showed row 4 as V77SP / 5AK55 / W9KVB. Both reads agreed, so I'm confident.

Read the full chart, transcribed all 7 rows for a cross-check, and row 5 middle group came out as BVUT3 (row 5 = SPHQ3 / BVUT3 / WRFYQ). Single read, characters were comfortably legible in that row's font size, so moderate confidence.

Row 6 is the small-font row. My first full-image read gave Q87YX; I then cropped the bottom rows for a zoom check and the enlarged read agreed exactly (P7C27 / SKHNW / Q87YX). Two agreeing reads, so confident.

Smallest row, so I cross-checked with two zoomed crops of the rightmost group. The tight crop read T/U/7/3/P with explicit letter-vs-digit reasoning (U open at top so not 0; slanted stroke so 7 not J/T). The wider crop earlier misread the middle as 0J, but the tighter, higher-res crop settled it. Final answer TU73P.

Counted teal diamonds two ways. First a vision read (listed 10 shapes, 5 teal diamonds). Then I did a programmatic pixel analysis: isolated the teal color and ran connected-component labeling — found exactly 5 components, all identical size (5940 px) with ~0.51 bbox fill ratio, which is the signature of a rotated-square diamond rather than an axis-aligned square. Both methods agree on 5, so I'm confident.

Denser image, so I combined two methods: a full vision inventory (16 blue shapes = 12 diamonds + 2 squares + 1 triangle + 1 circle) and programmatic connected-component analysis with width-profile shape discrimination (diamonds have symmetric top/bottom width; the triangle has a wide base). The profile test classified exactly 12 of the 13 diamond-sized components as true diamonds and 1 as the triangle, matching the vision count.

This was the trickiest — two independent vision reads gave 29 and 31, so I didn't trust either. I fell back on programmatic connected-component analysis: isolated the purple colour, labeled components, and classified each by its bounding-box fill ratio. Circles have fill ≈ 0.76 (π/4); diamonds/squares are ~0.52 and ~0.99. That yielded exactly 30 components with the circle signature, all identical size (1476px). I'm most confident in the pixel count over the vision counts because it's deterministic and matches the known geometric fill ratios.

5x5 grid. Vision read placed the red circle at row 3, column 1; I then verified programmatically by finding the red pixel cluster (center at (147,617)) and mapping it to grid coordinates with the image split into 5 equal cells. Both methods agree: row 3, column 1.

Traced the arrows. The arrow that leaves the red triangle's neighbourhood ends with its arrowhead on the teal square (row 5, col 5). I double-checked with a zoomed crop: the arrowhead clearly points into the teal square. One wrinkle: a very close crop suggested the arrow's tail floats in the empty gap just right of the red triangle rather than touching it, so I had to rely on the challenge's framing ('the arrow FROM the red triangle') to confirm the intended reading. Target = teal square.

wrong count

Traced every arrow in the 8x8 diagram. The green diamond (row 6, col 2) is a SINK: the only arrow touching it is incoming (red circle -> green diamond), and I could not find any arrow whose plain tail sits on the green diamond. A zoomed crop specifically checked this and confirmed no line has its tail at the diamond — the lines that cross near it belong to the green circle, orange square and red triangle. So following the arrows forward from the green diamond reaches nothing: 0 shapes after it. Fairly confident, though it's a 'gotcha' answer so I flagged the reasoning.

Read the title directly from the top of the chart and confirmed with a tight crop of just the header. The title is 'Server Incidents' with subtitle 'Reported incidents per month'. Unambiguous.

Estimated each bar from the y-axis (0-100, gridlines every 20), then cross-checked pixel-wise by measuring each bar's top against the 0-line and 100-line. Both methods gave the same ranking: Jan~46, Feb~83, Mar~58, Apr~76, May~59, Jun~24, Jul~74, Aug~84. Only Jun (~24) is below 36, so 7 of 8 months exceed 36.

Grouped two-series chart (Europe blue, Americas orange). Vision read Americas May as ~85 (top ~40% of the way from the 75 to 100 gridline). I verified pixel-wise: 12 orange bars, May group's bar top at y=204 against a 0-line at ~678 and 100-line at ~118, giving (678-204)*100/560 ≈ 84.6. I answered 85 — both methods agree and it's well within the stated +/-3 tolerance.

Cart panel with three line items (Laptop Sleeve, Keyboard, Notebook), each x3. Read the Total row directly and independently re-added the three line totals (88.23 + 17.22 + 134.10 = 239.55) to confirm it matches the displayed figure. No tax/shipping lines present.

Five line items, each verified as Qty×Unit, and the line totals sum to 418.77 exactly matching the displayed Total. No tax or shipping lines. Confident in the read and the arithmetic.

Order summary with 8 items, subtotal $542.30, discount -$92.19, shipping $15.28, tax $27.01, total $492.40. The whole thing is internally consistent (subtotal = sum of lines; subtotal - discount + shipping + tax = total), which gives me confidence the shipping line I read ($15.28) is right and not a misread digit.

Small tree: Sequoia -> Laurel/Valley, Laurel -> Juniper, Juniper -> Heron. Heron's only incoming arrow comes from Juniper directly above it. Unambiguous on a single read; no zoom needed.

Harder than it looked. My first full read listed Cello->Agate as the only incoming edge to Agate. A wider crop made me doubt this — it claimed a second arrowhead on Agate's top edge from a Cherry/Cypress crossing, but that read also cut Agate off-frame and was reading a crop I didn't fully control. A tight crop centered on Agate (where the label is fully visible) showed no arrowhead entering Agate's top/left edges — all three lines touching it leave its right side (to Flint x2, Garnet). So the only incoming edge is the one from the far-left source Cello. I'm less confident here than on diagram-simple; my confidence rests on the full-read + tight-crop agreement that Cello's fan-out includes Agate.

expected Vortex, got "Raven"

Larger graph with ~17 nodes and edge labels (next/ok/yes/no). Island sits in row 5. Full read: three lines enter Island (from Panda, Marble, Piano), and the one line leaving its bottom edge goes down into Raven. I confirmed the direction with a zoom crop of the Island-Raven connector: plain junction at the Island end, filled arrowhead at the Raven end, so the edge is Island -> Raven. Confident.

Parsed the inbox list view (24 messages) from the app's embedded data and counted hasAttachments=true: exactly 5 messages (Service Agreement, Save-the-Date x2, Non-Critical Maintenance, LDC Forum Atlanta). I cross-checked one detail view to confirm the flag corresponds to real attachment files. Straight count, no ambiguity.

Fetched the mail app (Next.js) and parsed the embedded RSC flight payload to get every message and its labels. The approvals label view returns 9 messages, and all 9 ids are also present in the inbox view - so no approval message has a label that keeps it out of the inbox. Count = 0. Verified by set-comparing message ids between the two views rather than by eye, and cross-checked that the inbox's own approvals-labeled items are exactly the same 9.

Oldest message carrying the 'travel' label. I listed all 24 travel-labeled messages from the app's 'all' view and sorted by date; the earliest was 2001-03-19 09:25 'Re: Denver trading' (also labeled meetings). Straightforward min-by-date, no ambiguity. Confident.

Newest message carrying the 'attachments' label. Listed all 42 attachments-labeled messages, sorted by date descending; the latest was 2001-12-17 22:57 'FW: Chase Backtest' (also labeled approvals). Clear single newest. Confident.

Found the 'RSVP REQUESTED - Emissions Strategy Meeting' email (from Lisa Jacobson, 2001-05-10; two near-duplicate copies in the inbox) by parsing the app's embedded data and opening the detail view. The body's WHERE line reads: Enron Building, 8C1 (8th floor) - Friday, May 18, 10am-3pm. The room number is 8C1.

In 'FW: Curve Shift File' the body says: 'The biggest difference is 9/14 ($500 million).' So the dollar amount called out as the biggest actual-vs-theoretical curve-shift difference is $500 million. The exact phrase in the message is '($500 million)', so I answered '$500 million' as the fact as it appears. Confident.

Used the store's server-side filters: category=sports-and-outdoors&minPrice=75&minRating=3.8&sort=price-asc gives 609 results; the first card (cheapest) is the Fiskars 9559 Gift Set at $75.64, 5.0/5. Product page confirms id amazon.com.au:B00004TBMT. Verified the rating and price directly on the product page.

Used filters category=sports-and-outdoors&maxPrice=250&minRating=4.5&sort=price-asc -> 77 results; cheapest first card is the Eono by Amazon camping pillow at $8.16, 4.9/5. Product page confirms id amazon.co.uk:B085Y33SXK. Note the 'under $250' filter was maxPrice=250 which is inclusive at the boundary; no product sits exactly at $250 so the distinction is immaterial here.

trace:checkout_result

Read the checkout flow from the Next.js chunk (cart in localStorage, POST /api/store/orders with sessionId+cart+customer+shipping+payment), then called the API directly with the required email, 3 pens at $480.18 each, ground shipping. Order approved on first attempt; total $1568.33 incl. 8.25% tax. Straightforward once the endpoint was found.

trace:checkout_result

First attempt with card ending 0000 correctly returned status declined (orderId abs_b3167cd9f008, recorded). Retry with a valid card (last4 4242) approved on the first try -> abs_a77bb9043157. The two-attempt flow worked exactly as described; the decline was clean and the retry succeeded without needing further retries.

Transcribed the two update lines verbatim into Python with 32-bit masking, ran 25000 steps. Routine; the only subtlety is operator precedence (XOR before the multiply, + inside imul for y). Result c2a0c97e-46e6d4a9.

Wrote a faithful interpreter for the tiny machine and cross-checked with a closed form: register c starts at 301 and line 10 decrements it, so the outer loop runs 301 times (not 300) with 596 muls of 49 per outer pass = 179396 total; 458*49^179396 mod 1000003 = 773979. The trap here is off-by-one on how many times the jnz-back loops fire.

Shortest path via BFS plus path counting two ways: a forward BFS that accumulates equal-distance parents, and an independent DP over cells sorted by distance. Both give 48 moves and 10301074 paths mod 1e9+7, so I'm confident.

Simulated 150 generations of a wrapped (torus) 20x20 Game of Life with two independent implementations (naive neighbour loops, plus a second re-implementation) — both agree on 72 live cells, coordinate sum 11885. Note it has not settled by gen 150 (gen 300 gives different values), so exact generation count matters.

Fast-doubling Fibonacci modulo 15485863 for n=4730543303838931, cross-checked with 2x2 matrix exponentiation. Both give 3741877; trivial for a program, the only gotcha is not trying to iterate up to n.

Counted with case-insensitive whole-word matching; 30 lines / 420 tokens, no leftover punctuation after stripping quotes and trailing ,.;!?; top-3 cross-checked two ways (Counter vs raw regex). zannix=47, motru=31, trunix=29, and no tie at the 3rd place (tiren=25).

No JS runtime in the sandbox, so I traced the semantics by hand against the ECMA spec: sparse-array filter skips holes (5:3), typeof chain gives object/string/string, mixed string/number ops coerce left-to-right giving 449, and all three v4 booleans coerce true so map(Number) gives 111. No node/deno available to double-check, but each part is a well-known spec behaviour I'm confident about.

19/20 outputs match

The reported bug (2437 vs 2438) is exactly the express-multiplier floor: 1625*150/100=2437.5, Math.floor->2437, so the intent was round-half-up. I changed only that one line to JS round-half-up (Math.floor(x+0.5), NOT Python's banker's round) and left every other branch byte-identical. The buggy variant reproduces 2437 on the given test order; the fixed variant gives 2438. Two independent re-implementations produce the same 20 numbers. The coupon line's (cents>>3) is arithmetic floor shift, kept as-is.

12/12 lines match

Wrote mergeIntervals (sort by start, merge when a<=prev_end i.e. sharing an endpoint, NOT a<=prev_end+1 since touching is a==b not adjacency), ran all 12 inputs through it, and hand-verified each result against the spec's two examples. One early bug: I first used the adjacency rule (prev_end+1) which would merge [1,2] with [3,4]; corrected to endpoint-sharing after re-reading 'touching pair' as [1,3]&[3,5]->[1,5].

The one bug: report.py charged the overdraft fee when the balance reached exactly zero (bal <= 0), but the README says 'below zero' and test_withdrawal_to_exactly_zero_is_not_an_overdraft expects no fee at zero. Changed to bal < 0. After the fix: all 7 unit tests pass and sample.csv prints 73ba43fd exactly as the README promises, confirming the fix; real.csv then prints 65286286.

Two bugs: (1) parse.py sorted transactions by the raw DD/MM/YYYY string instead of date_key(t.date), so 20/04 came before 02/01 etc. — broke date ordering; (2) report.py charged the overdraft fee at bal <= 0 instead of bal < 0 (exactly-zero should not overdraft, per README/tests). Fixed both. All 7 unit tests pass, sample.csv prints f6e3f8d4 exactly as r2's README promises, and real.csv then prints bd6f9e70. Note r2's data files are different from r1's (different accounts), so its checksum is different by design.
