# Invoice a landscaping firm's jobs from mowing areas, hedge height bands, mulch bags, contract discounts and tax on materials Inputs: `job-lines.csv` (line_id, job_id, client_id, service, area_m2, length_m, height_m, depth_cm; fields that don't apply to a service are blank), `clients.csv` (client_id, contract) and `rates.json`. All clients and jobs are synthetic; amounts are in dollars. These rules are the firm's price list; where `crew-note.txt` disagrees, the rules win. Rules: - Mowing: area_m2 × mow per_m2, rounded half-up to the cent, but never less than the mow min_charge for the line; a client with contract yes then gets contract_pct percent off each of its mowing lines (the discount rounded half-up to the cent). - Hedges: length_m × the per_m rate of the first hedge band whose max_height_m is at least the hedge's height_m (a height exactly on a band limit takes that band; the last band has no limit), rounded half-up to the cent. No contract discount. - Mulch: volume = area_m2 × depth_cm / 100 cubic metres; bags = volume / bag_m3 rounded up to a whole bag; the line is bags × bag_price (materials) + bags × spread_per_bag (labour). No contract discount. - Tax: each job pays tax_pct percent of its mulch materials only (bags × bag_price summed over the job), rounded half-up to the cent once per job; labour and services are not taxed. - Write `out/invoices.json`: `{"lines": {"<line_id>": <line amount after any discount>, ...}, "jobs": {"<job_id>": {"services": <sum of its line amounts>, "tax": <dollars>, "total": <services + tax>}, ...}, "clients": {"<client_id>": <sum of its job totals>, ...}}`. ## How this run works - Work on your own: nobody will answer questions in this task, and writing to `ask/` counts against the run. - Write only under `out/`. Create `out/` if it is missing. Inputs are synthetic; don't fetch anything from the network. - Scoring is partial credit: each listed check is pass/fail, and the score is the share passed. Numbers are compared to within 0.005 unless the task says otherwise.

Price a synthetic landscaping firm's job lines and roll them up into job and client invoices. Mowing has a per-square-metre rate with a minimum charge and a contract discount, hedges are priced by height band with heights exactly on the band limits, mulch is sold in whole bags worked out from area and depth, and only mulch materials are taxed. A crew note gets the discount, band, bag and tax rules wrong. Original benchmark task written for usecaserank.com (not based on a specific public post). Headless, offline run on a reproducible fixture. Each run's notes say how its cost was measured (estimates are marked).

Success criteria: mowing hedge_bands mulch_bags job_tax client_totals

Setup notes: Batch 38 case tz02-landscaping-job-invoicing (offline, synthetic inputs, seed 289958626). Autonomous case: no stand-in user and no step-ins expected; any file the solver wrote to ask/ is counted as a measured intervention (0) and blocks a pass. Prompt = TASK.md verbatim. Hidden key kept outside the solver's work dir. Scored with the case's scorer (python3 score.py WORKDIR KEYDIR, absolute paths); pass = every check true and no ask/ files. Tools: Read/Write/Edit/Glob/Grep/Bash, web disabled. Single run, no retries. 1-min load average at scoring 0.38 (8 cores). Time-zone results depend on the system time-zone database: tzdata 2026c-0+deb13u1 (Python zoneinfo). Rescored under checker v2 (zero-work entries may be omitted or listed at exactly 0) per President ruling Oct 25 2026; v1 score was 4/5 (client_totals failed only because clients.LC-7012 was listed at 0.0). v2: 5/5, pass. Evidence: score_output_rescored-tz02v2-2026-10-25.txt (sha256 ef5628a1617476a9b1bdccd1b695a2264de7234841d5dc649c9ccfa76850180a). The v1 result and v1 scorer log are kept unchanged as evidence (v1 scorer log sha256 9c4c47110057c2ea7caa64b45bbb662228ebdb7f283adda5dd47c0fbcc079531). Checker v2 sha256 0d48b624a7f23b61b28ca1a37abd4521880268636c33daab615b811924689ae6. Measured fields unchanged. Claude Code's own reported cost for claude-opus-5.5: $0.125201. Score: 5/5. Cost is an ESTIMATE: measured tokens x pricing.json list price (Claude Pro subscription, nothing billed); input_tokens include cache reads and writes. Single run.

Estimated cost List-price estimate; not actually billed.

I didn't run a separate check beyond confirming the arithmetic on a couple of lines by hand.\n\n**Client totals:**\n\n| Client | Total |\n|---|---|\n| LC-7001 | $515.17 |\n| LC-7012 | $0.00 |\n| LC-7023 | $584.85 |\n| LC-7034 | $597.89 |\n\nLC-7012 has no job lines. I listed it at $0.00 so every client appears; the task doesn't say whether clients without jobs should be included.\n\n**Where the crew note disagreed, I followed your rules:**\n- **Contract discount:** 15% off each mowing line only, not off the whole job. Every small mowing line hits the $30.00 minimum first, so the discount brings it to $25.50.\n- **Hedges on a band limit:** a hedge exactly at a limit takes that band, not the taller one. LN-501 is 2.5 m high, so it's charged $6.60/m, which comes to $99.66.\n- **Mulch bags:** always rounded up to a whole bag, not to the nearest. For example, LN-515 needs 18.67 bags, so it's charged for 19.\n- **Tax:** 8.5% on mulch materials only, rounded once per job, not on the whole invoice. Only the three jobs with mulch pay tax: JB-866 ($12.24), JB-875 ($23.66) and JB-878 ($9.79).\n\nThe calculations use exact decimals rather than floating point, so the rounding is exact.
