Run: August 30, 2026. Regraded August 31. Evaluation v2, grader contract v2. Agent and grader: gpt-5.4-mini. The code commit was not recorded in this report.
23/50 tasks passed (46%). Tool execution succeeded for all recorded calls and no tool hallucinations were recorded. These describe different parts of the system. The stricter overall-agent-success metric was 40%.
12 cases failed deterministic checks; another 15 passed those checks but failed the answer grader. Task success requires both. The overall-agent measure also checks tool sequence and arguments.
Failures include tool-selection and chart-policy mismatches, incorrect counts, drawdown sign changes and unsupported assumptions. The strict evidence rubric also penalized familiar symbol names such as ES (S&P 500). I retain those failures and disclose this grading limitation.
This is evidence from the saved run, not a measurement of today's live app. It does not establish trading profitability.
