Routine comparison. 1.94 > 1.90, so 1.94. Easy; the only trap would be treating 1.9 as longer-is-bigger, which it is not.

Straightforward once I followed the strict left-to-right rule instead of normal precedence: 29-2=27, 27-19=8, 8/4=2, 2+8=10. I noted that normal precedence would give 30.25, but the prompt was explicit so I went with 10.

Two-step unit conversion, easy. 13*60=780 minutes, then 780 GB at the decimal 1000 MB/GB convention given in the prompt = 780000 MB. The prompt itself settled the GB-vs-GiB ambiguity, so no guessing needed.

Multi-step integer arithmetic: 9+7=16, 6-31=-25, product -400, then 5*-1=-5, so -400-5-55=-460. Routine, no ambiguity since the parentheses are fully explicit.

agent's debrief
The hardest-looking one in this section, but a 4x4 determinant is mechanical. I did not trust mental arithmetic here: I computed it four independent ways (Bareiss fraction-free elimination, cofactor expansion along row 1, exact-fraction Gaussian elimination, and numpy float det rounded) and all four agreed on -2968, so I am confident.

Eye chart, row 4 group 3. Read it straight off the full-size image as WXVZ2, then cropped and 6x-upscaled that cell to double-check the Z/2 and V/X shapes - the zoom confirmed it. Char legibility at this size (20/20 row) was easy.

The hardest acuity item: row 7 is only a few pixels tall in the original. A 14x crop made it readable - FK3NG. I checked the third glyph is a 3 (open left side) rather than E or B, and the last is G not 6, since 6/G confusion bit me on the previous chart.

Counted 8 purple triangles by eye row by row, then re-counted with the connected-component script: it found 22 shapes total, 15 of them purple, of which 8 have triangle geometry (8 purple squares and 1 purple circle make up the rest). Eye count and script agree, so I am confident.

agent's debrief
This one was dense - 57 shapes, several colours and four shape types - so counting by eye alone felt unreliable. I used two independent scripted counts (background-difference flood fill, then a colour-threshold mask with scipy.ndimage.label). Both found 29 blue shapes: 22 axis-aligned squares, 3 diamonds, 3 circles, 1 triangle. Teal is a clearly different RGB, so I did not count it as blue.

agent's debrief
I read the arrow as purple square to the orange triangle by eye, then confirmed with a script that isolated the near-black arrow pixels, found the arrowhead end by local pixel thickness, and matched endpoints to shape centres. It reported purple square -> orange triangle (head 74 px from the triangle, next best candidate 135 px away), so the identification is unambiguous. Note the orange triangle also has an outgoing arrow to the purple diamond, so direction mattered.

agent's debrief
Hardest spatial item: 8x8 grid, 64 shapes, 13 crossing arrows. My first attempt (connected components of the dark arrow pixels) was wrong because crossing arrows merged into one component, so I rewrote it to find arrowheads by local density, then walk straight back along each line through intersections. That gave a clean 13-edge graph (each head blob the same ~58 px, so detection looks complete). Backwards from the teal square: orange square -> teal square, purple circle -> orange square, teal circle -> purple circle, so three steps before is the teal circle. I confirmed all three links visually in a 2x crop.

Routine bar-chart read. By eye Jan looked like ~27. I measured it with pixels to be sure: gridlines at y=120/220/320 give 10 px per unit and the zero axis at y=619.5, so the Jan bar top at y=350 is 26.95, i.e. 27. The other bars came out at 21, 15, 15, 21, which matches the visual spacing.

Counted by eye: 6 of the 8 months sit above 28. I confirmed with pixel measurement (gridlines at y=119.5/227.5/335.5 for 100/80/60, so 5.4 px per ticket, baseline y=659.5): Jan 47, Feb 71, Mar 53, Apr 10, May 19, Jun 86, Jul 58, Aug 52. Only Apr and May fall below 28, and they are far from the threshold, so the count is not borderline.

agent's debrief
Grouped bar chart, needed pixel measurement because the two Oct bars differ by only about half a gridline. Gridlines at y=119.5/259.5/399.5/539.5 for 100/75/50/25 (5.6 px per ticket), baseline y=679.5. Oct Europe bar top y=507 -> 30.8 (~31); Oct Americas top y=372 -> 54.9 (~55). Difference 24.1, so 24. Within the +/-4 tolerance the answer is safe even if the true values are 31/54 or 31/55.

Straightforward read of the Total line: .84. I double-checked it by adding the five line totals (84.51+17.82+16.76+40.82+78.93 = 238.84) and they match, and the qty*unit products are consistent too, so the cart maths is self-consistent and I am confident.

Small grey text, so I cropped and 2x-upscaled the subtotal/discount/shipping/tax block: the Discount line reads -.46. Cross-checked the arithmetic: the ten line totals sum to 385.05, matching the Subtotal, and 385.05 - 65.46 + 5.57 + 19.18 = 344.34, matching the Total - so 65.46 is right. I gave the magnitude without the minus sign since the question asked for the discount amount.

Busier graph (11 boxes, ~15 arrows), so I extracted it with a script: lavender box fills gave me the 11 boxes, dark pixels outside boxes gave the arrowheads, and each arrowhead was matched to the box it touches plus the box its line comes from. Puffin has exactly one incoming head, at its left edge (588,185), whose line comes from the Coyote box - so Coyote -> Puffin. Note Puffin also has an outgoing arrow to Kiwi, so direction mattered. The ray-back step was flaky for a few heads (arrowhead barbs bias the direction estimate) but the head-to-box matching was unambiguous here.

agent's debrief
This graph is dense - 20 boxes, 34 arrowheads, lots of elbow-routed and crossing lines - so my scripted ray-back step gave wrong sources for several edges. I fell back on a 3x crop centred on Cobalt: one line leaves Cobalt's right edge and runs down-right into an arrowhead at Saddle's left edge, and that is Cobalt's only outgoing line. The script agreed for this specific head at (564,492): traced back 87 px it reaches the Cobalt border, and it touches Saddle. Cobalt's other adjacent head at (379,447) is an incoming arrow from Puffin.

The mailbox UI has no per-row attachment icon, so I went for the data behind the page: the Next.js RSC payload embedded in each page contains full message objects with a hasAttachments flag. Paging through view=archive (4 pages) gave all 92 archive messages, 22 flagged hasAttachments=true. Cross-check: the per-folder sweep gives inbox 5, sent 17, drafts 0, archive 22, trash 0 = 44, exactly the total for view=all, so the extraction is internally consistent. The sidebar label 'Attachments' says 42, which I ignored as a label count rather than a folder count.

Straightforward browser checkout: set quantity to 3 on the product page, added to cart (subtotal 3 x .40 = ,353.20), then filled the checkout form with the given email and the pre-filled test card (4242...4242, 12/30, 123) plus placeholder shipping details. The confirmation page shows Order ID abs_e80325b63fc5 with status approved, Qty 3, and I also clicked Submit receipt, which changed Receipt status to Saved. I used a generic name (Alex Tester) rather than any real identity.

I stayed on the same checkout page, kept the email, swapped in a different valid card (4242424242424242) and placed the order again - confirmation page shows Order ID abs_a46208cece83, status approved, Qty 3, receipt already Saved.

Write and run a short program to compute this exactly. Use unsigned 32-bit arithmetic modulo 2^32 throughout. Define rotl32(z, r) = ((z << r) | (z >> (32 - r))) mod 2^32, and let imul(a, b) mean 32-bit multiplication modulo 2^32. Start with data = [1428383339, 3592867368, 3404258889, 1687831326, 2330921271, 211921508, 713735861, 3581321594, 2510723651, 1024219616, 3752909665, 3012491542], x = 1681540495, y = 2223503516 and rounds = 25000. For each step from 0 to rounds - 1 apply: x = (imul(x XOR data[step % 12] XOR step, 2654435761) + rotl32(y, 5)) mod 2^32; y = (imul(y + data[(step + 7) % 12] + step, 1597334677) XOR rotl32(x, 11)) mod 2^32; x = (x + rotl32(y XOR step, 3)) mod 2^32.

Routine 'write and run' task, no difficulty. The only traps were the update order (x is updated before y uses it) and remembering that y's new value feeds the third x line - I applied the three statements strictly sequentially as written. I re-implemented it independently in JavaScript with Math.imul/>>>0 and got the identical pair, so I am confident in the masking semantics.

Write and run a program to execute this tiny machine exactly. It has four registers a, b, c, d, all starting at 0, and a program counter starting at line 0. `set r n` sets r to n. `add r x`, `sub r x` and `mul r x` combine r with x (a register name or an integer), then reduce r modulo 1000003 into the range 0..1000002. `dec r` subtracts 1 from r. `jnz r k` jumps k lines (relative; k may be negative) if r is not 0. `halt` stops. Every other instruction moves to the next line. 0: set a 391 1: set b 691 2: set c 362 3: set d 541 4: sub a 54 5: add b a 6: sub b a 7: dec d 8: jnz d -4 9: mul a 21 10: dec c 11: jnz c -8 12: halt Respond with just the final value of register a.

Wrote a proper interpreter with a program counter, modulo 1000003 after add/sub/mul, and relative jnz; it ran 980,662 steps and gave a=977802 (b stayed 691, which made me pause - but add b a followed by sub b a cancels, so that is expected). I checked independently: the inner d-loop is just a -= 54*541, so a = ((a-29214)*21) mod 1000003 repeated 362 times - same answer - plus a plain nested-loop version. My first cross-check script was buggy (it did not reset a), which is why I re-ran it.

BFS with path counting: the shortest path is 50 moves (2 above the 48-move Manhattan minimum, so the walls force one small detour) and there are 7776 shortest paths - small enough that the mod 1e9+7 never bites. I re-counted independently with a DP over BFS layers (summing predecessors at distance d-1) and got the same 7776, so the counting step is solid.

Standard simulation - the only real risks were the wrap-around and mistyping the seed grid. I ran it twice: once with a sparse neighbour-count dictionary over my transcribed grid, and once with a numpy np.roll convolution after parsing the 20 grid lines straight out of the saved challenge JSON. Both started at 128 live cells and ended after 150 generations at 33 live cells, index sum 8119.

Programmatic, not by eye. I took the text straight from the saved challenge prompt instead of retyping it, which removed transcription risk. 420 tokens, 30 distinct words. There is a tie for third place - mopel and shalu both 27 - and the stated rule (ties alphabetically) puts mopel third. I recounted with a different tokenizer (replace every non-alphanumeric with a space, then regex words) and got identical counts.

I ran the snippet in node rather than reasoning about it, since half of it is coercion and floating-point trivia. Results: string concat then subtraction gives 794; the var-loop closures all see v2i=3 so v2=63; the float comparison really is exactly equal (0.1*5=0.5, 0.2*5=1.0, 0.3*5=1.5); and the sparse array has length 9 but filter skips the holes, giving 9:3. console.log joins with single spaces.

agent's debrief
The reported case pinpoints the express surcharge: 1279 cents x 150% = 1918.5, and Math.floor truncates it to 1918 where 1919 is wanted, so the bug is the rounding mode on the express multiplier. I changed Math.floor to Math.round and nothing else. One honest uncertainty: ceil would also fix the reported case, but I checked all 20 orders and round and ceil give identical values there, so the submitted list does not depend on that choice. I re-ran the whole thing in JavaScript itself (the original language, with its float quirks) and got the same 20 numbers, and the reported order now quotes 1919.

Write a function mergeIntervals(intervals). Each interval is a pair [start, end] of integers with start <= end, and includes both ends. It returns the intervals with every overlapping or touching pair merged (so [1, 3] and [3, 5] become [1, 5], but [1, 2] and [3, 4] stay apart), sorted by start. The input may be in any order. Run it on each of the 12 inputs below and respond with one line per input: the result as JSON, like [[1,5],[8,10]]. Spaces are ignored. [] [[1,3],[3,5]] [[1,2],[3,4]] [[5,9],[1,10]] [[22,30],[5,6],[18,23],[22,25],[30,38],[30,36],[3,7],[39,41]] [[20,27],[17,21],[39,46]] [[24,29],[6,6],[33,33],[23,31],[29,29],[23,25]] [[8,12],[15,23],[5,7],[15,19],[25,31]] [[26,30],[16,23],[17,22],[27,32],[24,29]] [[36,42],[2,6],[38,44],[31,37],[35,39],[28,32],[17,21]] [[1,2],[17,24],[25,26],[2,7],[31,33],[29,30],[35,36]] [[5,8],[8,11],[8,15],[20,24],[10,14],[19,20],[36,36]]

agent's debrief
I nearly got this one wrong through my own default: my first version merged adjacent integer intervals (s <= end + 1), which turned [1,2] and [3,4] into [1,4]. The prompt's own examples ([1,3]+[3,5] merge, [1,2] and [3,4] stay apart) contradict that, so I asserted both examples in the code and switched to strict overlap (s <= end). That changed several of the 12 lines - for example [[26,30],[16,23],[17,22],[27,32],[24,29]] is [[16,23],[24,32]], not [[16,32]]. A second, independent endpoint-sweep implementation produced identical output for all 12.

Single bug in report.balances: the overdraft test used bal <= 0, so a withdrawal that lands the balance exactly on zero was also charged the 3,500-cent overdraft fee, contradicting the README ('below zero'). The repo's own test suite named it (test_withdrawal_to_exactly_zero_is_not_an_overdraft), and after changing <= to < all 7 tests pass and data/sample.csv prints b73b1056 exactly as the README requires - that reference hash is what makes the fix unambiguous. real.csv then prints 42fddf8b (160 transactions, 5 accounts, 19 overdraft charges).

This repo had two bugs. (1) fees.withdrawal_fee used -(-cents // 100), i.e. ceiling, where 1% rounded down is wanted, so a 50,050-cent withdrawal was charged 501 instead of 500 - fixed to cents // 100. (2) parse.load sorted by the raw date string, which is DD/MM/YYYY, so it ordered by day first and only got the year last - fixed to sort on (year, month, day) while relying on Python's stable sort to keep file order within a date. The second bug was not caught by the test suite (only the fee bug had a failing test), so the oracle I used is the README's required sample hash: after both fixes all 7 tests pass and data/sample.csv prints 6404e41d exactly. real.csv prints a7a0c91a (160 transactions, 5 accounts, 41 overdraft charges).
