ID Claim/question Source Type Date Finding Reliability Supports Contradicts / limits
EV-E001 Can realistic coding tasks be broken? OpenAI benchmark audit Primary first-party audit 2026-07-08 Agent audit flagged 27.4%; human review identified 34.1% as broken; major defects were strict tests, underspecification, low coverage, and misleading prompts High for audited dataset HY-E002, HY-E004 One benchmark family; vendor authored
EV-E002 Can a once-useful benchmark lose validity? OpenAI on SWE-bench Verified Primary first-party audit 2026-02-23 Contamination and test-width problems reduced useful frontier signal High for dataset diagnosis HY-E002, HY-E006 Does not quantify transfer to AI-ROS
EV-E003 What grader mix is recommended for agents? Anthropic, agent evals Engineering practice report 2026-01-09 Code, model, and human graders have complementary strengths; outcome and transcript can both matter Medium-high HY-E003 Not a controlled comparison; vendor practice
EV-E004 Does repository prompt construction affect results? Time-consistent repository benchmark Research preprint 2026-03-27 Prompt granularity materially changed file-level performance; temporal consistency is a validity concern Medium HY-E002, HY-E006 Limited repositories/models; preprint
EV-E005 Can web access contaminate research-agent evals? Search-Time Contamination Research preprint 2026-06-03 Public benchmark information retrieved at inference inflated reported performance by up to 4% Medium HY-E006 Six public benchmarks; detection methods need replication
EV-E006 Is final-state evaluation useful beyond code? STAGE-Claw Research preprint 2026-06-09 State-based environments enable executable checks for realistic personal-agent tasks Medium HY-E003 Automated task generation can introduce new defects
EV-E007 Can generated held-out cases reduce contamination? Power Systems Agent Benchmark Research preprint 2026-06-18 Private-seed cases and deterministic recomputation reduce answer leakage; unanimous failures exposed an evaluator bug Medium HY-E002, HY-E003, HY-E006 Domain has unusually formal ground truth
EV-E008 Do current repository artifacts support a task suite? Repository inspection and Git history at 0205032 Direct observation 2026-07-23 Repository supports provenance, cross-file editing, link, research, recovery, and adversarial task families; coding history is sparse High HY-E001 No task has been instantiated or audited yet
EV-E009 Are repository-native tasks automatically valid? Comparison of EV-E001, EV-E004, EV-E008 Inference 2026-07-23 No. Native history can retain hidden context, narrow reference behavior, leakage, and unrepresentative sampling Medium-high HY-E002 Must be tested during pilot audit
EV-E010 Can benchmark protocols expose shortcuts that invalidate capability claims? Shao et al., protocol validity Research preprint 2026-07-24 Audit of 2,385 traces reports exposures/reward hacking in some benchmark families and proposes an exploit-vs-intended “Mislead gap” Medium HY-E002, HY-E006 Very recent preprint; benchmark-specific rates cannot transfer to AI-ROS
EV-E011 Is evaluation isolation a real security requirement? OpenAI/Hugging Face evaluation incident Primary incident report 2026-07-21 An agent used in cyber-capability evaluation compromised infrastructure, showing evaluation environments can create real external risk High for incident occurrence HY-E009 Extreme cyber setting; does not quantify ordinary repository risk
EV-E012 Are fixed predeployment evals sufficient for long-horizon systems? OpenAI long-horizon safety report Primary first-party report 2026-07-20 Novel failures appeared during limited use; report recommends monitoring, safeguards, visibility, pausing, and rollback alongside evals Medium-high HY-E009, HY-E010 One developer’s internal system
EV-E013 What economic denominator matters? OpenAI, AI scorecard First-party economic argument 2026-07-17 Cost per successful outcome should include attempts, time, and human review rather than tokens alone Medium HY-E011 Conceptual/company source; value measurement remains use-case-specific
EV-E014 Do the pilot deterministic graders distinguish declared probes? python3 tools/evaluation/evalctl.py all Direct executable observation 2026-07-28 Both contracts validate and all seven declared calibration classifications match High for supplied probes HY-E003 In-sample designer probes; no agent or independent reviewer
EV-E015 Can pilot fixtures be exported without gold/probe exposure? python3 tools/evaluation/evalctl.py prepare --output <temporary-directory> Direct executable observation 2026-07-28 Both fixtures exported with visible task materials only; exposure detector reported false for both High for current exporter HY-E006, HY-E009 Filename/content checks are narrow; independent security audit absent
EV-E016 Did tracked case-only paths threaten repository reproducibility? Git index and blob audit at 9b96b13 Direct repository observation 2026-07-28 Three case-only pairs existed; each pair had identical content but collapsed on the current case-insensitive filesystem High HY-E006 Resolved in index; cross-platform checkout still needs post-commit verification

Evidence Quality Notes

  • EV-E001 and EV-E002 are strong direct evidence about benchmark failure modes, not proof of their prevalence in AI-ROS.
  • EV-E004–EV-E007 are recent preprints and should guide design provisionally, not establish theory.
  • No empirical AI-ROS run evidence exists yet. Any performance claim before Cycle 002 is invalid.
  • EV-E014 is empirical grader evidence, not agent capability evidence. It cannot establish external validity.
