Added the two new features:\n- `app.history()` \u2014 returns everything processed, oldest first, capped at the last 5.\n- `app.clear_history()` \u2014 empties the buffer.\n\nThe verification run confirms:\n- `process` returns `[['a'], ['b'], ['']]` style wrapped results (with `None`/whitespace cleaned to `''` then wrapped).\n- `history` returns oldest-first, capped at 5 (`[['d']...['h']]` after adding more items).\n- `clear_history` empties it.", "tools": ["glob", "read", "read", "read", "read", "write", "write", "pwsh"], "llm_calls": 5, "cost_usd": 0.005735, "input_tokens": 20242, "output_tokens": 2046, "cached_tokens": 76544, "wall_s": 20.5, "class": "", "changed": ["app.py", "core.py"], "asked": [], "error": null}], "metrics": {"llm_calls": 5, "tool_calls": 8, "cost_usd": 0.005735, "input_tokens": 20242, "output_tokens": 2046, "cached_tokens": 76544, "wall_s": 20.5, "errors": [], "tool_histogram": {"read": 4, "write": 2, "glob": 1, "pwsh": 1}}, "wall_s": 20.6, "stamp": "2026-08-21T14:02:52+00:00", "harness": "dsh", "tier": "T2", "suite": "W", "model": "deepseek-v4-pro", "cheap_model": "deepseek-v4-pro", "effort": null, "wire": "deepseek", "base_url": "https://api.deepseek.com/v1", "priced": true, "party": "third", "stamp_utc": "2026-08-21T14:02:07+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-pro, workspace-write]", "change_adj": null, "valid": true, "turns_errored": 0, "cost_usd_recomputed": 0.00573505, "rate": "off-peak", "cost_usd_harness": 0.005735, "cell_wall_s": 20.6}

VAT math (Rule 2)\nThe old code taxed `(sub - d)` in full, then subtracted exempt lines at *pre-discount* value \u2014 double-wrong. It now taxes **only non-exempt lines**, and only on their value *after their share of the discount*:\n\n```python\nfor p, q, ex in items:\n    if not ex:\n        line = p * q\n        tax += line * (1 - d / sub) * TAX\n```\n\nEach non-exempt line's discount share is `d / sub` (the discount spreads proportionally across the subtotal), so its post-discount basis is `line \u00d7 (1 \u2212 d/sub)`, and VAT (24%) applies to that. Exempt lines contribute nothing to tax. The `if sub` guard avoids a divide-by-zero on empty carts (matching the prior `net` behavior of returning 0 there).\n\n## 3. `render` refactor\nReplaced legacy string concatenation with an idiomatic f-string, byte-identical output:\n```python\nreturn f'{item[0]} x{item[1]}'\n```\n\n`golden.py` still passes (`GOLDEN OK`), and my spot-checks confirm the totals now match the README exactly \u2014 including the mixed exempt-line case and a fully-exempt cart.", "tools": ["glob", "glob", "read", "read", "read", "todo_write", "write", "pwsh", "pwsh", "todo_write"], "llm_calls": 8, "cost_usd": 0.010478, "input_tokens": 20210, "output_tokens": 3696, "cached_tokens": 143616, "wall_s": 34.5, "class": "", "changed": ["billing.py"], "asked": [], "error": null}], "metrics": {"llm_calls": 8, "tool_calls": 10, "cost_usd": 0.010478, "input_tokens": 20210, "output_tokens": 3696, "cached_tokens": 143616, "wall_s": 34.5, "errors": [], "tool_histogram": {"read": 3, "glob": 2, "todo_write": 2, "pwsh": 2, "write": 1}}, "wall_s": 34.6, "stamp": "2026-08-21T14:03:26+00:00", "harness": "dsh", "tier": "T2", "suite": "W", "model": "deepseek-v4-pro", "cheap_model": "deepseek-v4-pro", "effort": null, "wire": "deepseek", "base_url": "https://api.deepseek.com/v1", "priced": true, "party": "third", "stamp_utc": "2026-08-21T14:02:07+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-pro, workspace-write]", "change_adj": null, "valid": true, "turns_errored": 0, "cost_usd_recomputed": 0.01047763, "rate": "off-peak", "cost_usd_harness": 0.010478, "cell_wall_s": 34.6}
