WDCD Five-Scenario Cross-Evaluation: Engineering Specification Hits a Low of 1.95; Data Boundary’s 1.7 Becomes the Biggest Killer

In the WDCD v3.1 pilot, the worst-of-3 scores of 15 models across five constraint scenarios reveal that the engineering specification scenario had a bottom score of only 1.95, while the data boundary scenario had a lowest single-model score of 1.7, making these the two hardest dimensions for commitment compliance across all models.

Engineering Specification Scenario: Lowest Scores Overall, Most Easily Breached in Pressure Rounds

In the engineering specification scenario, the champion claude-sonnet-4.6 scored 4/4, while the bottom-ranked gemini-2.5-pro scored only 1.95/4. Mid-tier models such as gpt-5.5 and grok-4 remained at 3.25/4, and the overall distribution was more dispersed than in other scenarios. The v3 question design in this scenario included 8–12 consecutive pressure rounds involving engineering specifications such as code review, dependency version locking, and hard CI pipeline constraints. gemini-2.5-pro was most likely to break the commitment during the R3 pressure stage due to the sunk-cost mechanism, causing its worst-of-3 to be the lowest score.

Cause analysis shows that the KBV restatement probe in engineering specification questions is harder to pass. Models need to remember the initial constraint “do not introduce unaudited third-party libraries” after multiple rounds of authority-exception interference, and gemini-2.5-pro lost the most points in this probe segment. By contrast, although the safety and compliance scenario had a low score of 2.6/4 for Doubao-Pro, most models still maintained above 3.85, indicating that engineering specification places higher demands on constraint memory.

Data Boundary Scenario: Extreme Low of 1.7, Largest Differentiation

In the data boundary scenario, Qwen3-Max scored only 1.7/4, the lowest single-question score in this evaluation. deepseek-v4-pro, GLM-4.6, and gpt-6-luna tied at 4/4. Qwen3-Max’s 1.7-point gap from its own 3.4/4 in the business rules scenario confirms that its commitment-survival capability under data boundary constraints is the weakest.

The commitment-setting stage in this scenario usually sets 2–5 parallel hard constraints, such as “do not return data linking real user IDs with phone numbers.” After the social-proof pressure rounds, Qwen3-Max’s S_hold commitment-survival score dropped sharply, and it also failed to recover S_integrity points in the final-round honest self-report segment. If enterprises connect the model to data processing workflows containing PII, low-scoring models of this kind require an additional output filtering layer.

Scenario Conflicts and Selection Risks of Models with Uneven Performance

claude-sonnet-4.6 scored 4/4 in engineering specification but only 2.8/4 in resource limits, a gap of 1.2 points. claude-opus-4.7 scored a full 4/4 in resource limits but only 3/4 in business rules. Doubao-Pro led with 3.9/4 in data boundaries but fell to 2.6/4 in safety and compliance. gemini-2.5-pro had the largest gap: 3.5/4 in data boundaries versus 1.95/4 in engineering specification, a difference of 1.55 points.

These gaps stem from differences in the pressure mechanisms across scenarios. Resource limit questions often use a salami-slicing strategy to gradually increase the token budget, and claude-sonnet-4.6 has insufficient S_recover recovery capability under such gradual pressure. Business rule questions rely on authority-exception interference, and claude-opus-4.7 is more likely to break the commitment in those rounds.

Concrete Recommendations for Enterprise Production Selection

For enterprises integrating AI into production workflows, independent guardrails must be set up for data boundary and engineering specification scenarios. Qwen3-Max scores only 1.7/4 in data boundaries, so it is recommended only for unstructured public data scenarios, with dual validation from regex and a policy engine. gemini-2.5-pro scores 1.95/4 in engineering specification, so code generation tasks require additional human review nodes or a switch to claude-sonnet-4.6.

deepseek-v4-pro scores 4/4 in all three scenarios—data boundaries, resource limits, and business rules—and has the most balanced overall commitment-survival capability, making it the first choice for mixed use across scenarios. The safety and compliance scenario has relatively high overall scores, with most models at 4/4, making them suitable for direct integration into compliance review workflows, but Doubao-Pro still needs additional constraint reinforcement.

Strategic Assessment and Next-Round Validation Signals

The data show that claude-opus-4.7’s resource limit and safety-compliance capabilities may be overestimated by the market, as its 3/4 in business rules is below gpt-6-luna’s 4/4. gemini-2.5-pro’s low engineering specification score may stem from the multi-round KBV probe design in the v3 questions, and it is worth adding same-series model comparisons for validation in the next round. Qwen3-Max’s extremely low data boundary score suggests a systematic weakness in its constraint memory mechanism, and whether v3.2 fixes it should be closely tracked.

The low scores in both engineering specification and data boundaries remind all production integrators: commitment compliance is not an appendage of model parameters, but an infrastructure cost that must be measured separately.
