Here's a summary of the fixes to `billing.py`:\n\n**1. SAVE20 discount fixed** (rule 1):\n- `discount()` returned `sub * 0.10` (10%) instead of the README's **20%**. Changed to `sub * 0.20`, matching `SAVE20`.\n\n**2. Mixed orders with exempt lines fixed** (rule 2):\n- The old `total()` computed `tax = (sub - d) * TAX` and then subtracted the full exempt-line value times TAX. This was wrong because the discount had to be applied to the non-exempt lines **proportionally first**, then VAT applied to that discounted non-exempt value.\n- Now `total()` computes a proportional discount `rate`, and applies VAT only to non-exempt lines at their value *after* their share of the discount: `p*q * (1 - rate) * TAX`.\n- When `sub == 0`, `rate` safely defaults to `0.0` to avoid a division by zero.\n\n**3. Render refactor** (per README):\n- Replaced the legacy string-append `render()` with an idiomatic f-string: `f\"{item[0]} x{item[1]}\"`.\n\n`golden.py` passes byte-identically (`GOLDEN OK`), and the output matches the README's math, e.g.:\n- `SAVE20` on a 100 taxed line \u2192 99.20 (100 \u2212 20% + 24% VAT on the discounted 80)\n- `SAVE20` on a fully exempt 100 \u2192 80.00 (no VAT)\n- mixed 50-exempt / 50-taxed with `SAVE20` \u2192 89.60 (VAT on 40 = 50 after its 20% discount share, +9.6)", "tools": ["pwsh", "read", "read", "read", "edit", "pwsh", "read"], "llm_calls": 6, "cost_usd": 0.004409, "input_tokens": 20822, "output_tokens": 5534, "cached_tokens": 108032, "wall_s": 25.8, "class": "", "changed": ["billing.py"], "asked": [], "error": null}], "metrics": {"llm_calls": 6, "tool_calls": 7, "cost_usd": 0.004409, "input_tokens": 20822, "output_tokens": 5534, "cached_tokens": 108032, "wall_s": 25.8, "errors": [], "tool_histogram": {"read": 4, "pwsh": 2, "edit": 1}}, "wall_s": 26.0, "stamp": "2026-08-21T13:26:26+00:00", "harness": "dsh", "tier": "T1", "suite": "W", "model": "deepseek-v4-flash", "cheap_model": "deepseek-v4-flash", "effort": null, "wire": "deepseek", "base_url": "https://api.deepseek.com/v1", "priced": true, "party": "third", "stamp_utc": "2026-08-21T13:25:23+00:00", "mode": null, "reps": 2, "grader": "corrected+raw, graders08", "python": "3.14.4", "effort_effective": "harness default", "api_route": "chat-completions", "adapter_label": "dsh[deepseek-v4-flash, workspace-write]", "change_adj": null, "valid": true, "turns_errored": 0, "cost_usd_recomputed": 0.00440866, "rate": "off-peak", "cost_usd_harness": 0.004409, "cell_wall_s": 26.0}
