# Invoice a plumbing firm's jobs with a call-out hour, labour in started quarter hours, emergency rates and banded parts markup Inputs: `jobs.csv` (job_id, customer_id, arrive, depart, emergency), `parts.csv` (line_id, job_id, part, qty, unit_cost), `customers.csv` (customer_id, name, service_plan) and `rates.json` (callout_fee, labour_per_hour, emergency_multiplier, markup_bands, tax_pct). All customers and jobs are synthetic; amounts are in dollars and times are local. These rules are the firm's policy; where `office-note.txt` disagrees, the rules win. Rules: - Labour: the first 60 minutes on site (depart − arrive) are covered by callout_fee, charged even for a shorter visit; time beyond 60 minutes is billed in started 15-minute blocks at labour_per_hour ÷ 4 per block; customers whose service_plan is 'yes' pay no callout_fee (their blocks are still charged); an emergency job ('yes') has its whole labour charge multiplied by emergency_multiplier, rounded half-up to the cent. - Parts: each part line is marked up by the first band in markup_bands whose max_unit_cost is at least the line's unit_cost (null = no limit); line price = qty × unit_cost × (100 + pct) / 100, rounded half-up to the cent. - Tax: tax_pct of the job's parts total, rounded half-up to the cent per job; labour is not taxed. Job total = labour + parts + tax. - Write `out/invoices.json`: `{"parts": {"<line_id>": <dollars>, ...}, "jobs": {"<job_id>": {"labour": <dollars>, "parts": <dollars>, "tax": <dollars>, "total": <dollars>}, ...}, "customers": {"<customer_id>": <sum of the customer's job totals>, ...}}`. `parts` has one entry per row of parts.csv and `jobs` one entry per row of jobs.csv (a job with no parts has parts 0 and tax 0). - Roll-ups: Customers in customers.csv with no jobs are left out. ## 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.

Invoice a synthetic plumbing firm's jobs. A call-out fee covers the first hour (waived for service-plan customers), later time is billed in started quarter hours, emergencies multiply the labour, parts are marked up by cost bands with unit costs exactly on a band limit, and tax applies to parts only. The prompt says customers with no jobs are left out of the roll-up. An office note gets the rounding, call-out and roll-up 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: labour parts_markup tax job_totals customer_totals

Setup notes: Batch 39 case tk02-plumbing-job-invoicing (offline, synthetic inputs, seed 193167591). 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 0.27 (8 cores). Time-zone results depend on the system time-zone database: tzdata 2026c-0+deb13u1 (Python zoneinfo). Claude Code's own reported cost for claude-haiku-5.5: $0.004436. 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.
