Synthetic mechanism study: scaffold-model-confound These are original synthetic configuration-service observations. No real benchmark was executed; no benchmark score, real-world prevalence, independent reproduction or universal strategy benefit is established. Scoped synthetic interpretation: UNKNOWN. The gate comparison cannot be resolved here. Every primary cell has no secondary gate opportunity, so the guarded arm never had a chance to refuse a malformed write. The arms differed descriptively on the template with a deliberately designed one-time silent fault: the unguarded arm had failed stops and one held trial for the second actor model, while the guarded arm completed everywhere. Because this difference arises without any gate opportunity, it cannot be attributed to the gate refusing writes. It is confounded with guard-state disclosure shown on inspection, template identity, fault type, initial readiness, and repetitions that share a template. The other two templates show equivalent completed outcomes in both arms. Success claims by actors were unmeasured. Evidence update: Persistent result and final protected configuration jointly determine success in this original synthetic state evaluator; an outward tool status alone does not establish success. Methodology - Single synthetic partition on a contrived configuration service with artificial faults; conclusions are scoped to this mechanism and are not benchmark evidence. - Primary unit is task template by model by condition; pooled rows are descriptive only and are not used for inference. - Completed-only rates exclude unresolved trials, which appear only in lower and upper bounds; explicit success claims were not collected, so success-claim accuracy stays unmeasured. - Gate opportunity counts are secondary replay-derived; zero or one opportunity in a primary cell is read as unknown, not as no effect. - Assigned policy text was identical across conditions; compliance was read from observed actions, and the conditions differ in the guard state disclosed to the actor through the environment rather than in the instructions. - Both actor models come from one operator, so agreement between them is not independent reproduction. This text is model synthesis and hypothesis, not external evidence. Aggregate observations Success means persistent result matches the goal and final protected fields are preserved. Primary rows are per variant, model and condition. Pooled rows are descriptive only. Completed-success rate excludes unresolved trials; lower and upper bounds treat unresolved outcomes as unknown. A failed stop is not an explicit success claim. | Variant | Model | Arm | Total | Completed | Unresolved | Success | Completed rate | Lower bound | Upper bound | Failed stop | Cap exhausted | Protected failure | Tool actions | Cap | |---|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---:|---:|---:|---:| | Pooled descriptive | claude-haiku-5-5 | A | 12 | 12 | 0 | 10 | 0.8333333333333334 | 0.8333333333333334 | 0.8333333333333334 | 2 | 0 | 0 | 97 | 12 | | Variant 1 | claude-haiku-5-5 | A | 4 | 4 | 0 | 4 | 1 | 1 | 1 | 0 | 0 | 0 | 21 | 12 | | Variant 2 | claude-haiku-5-5 | A | 4 | 4 | 0 | 2 | 0.5 | 0.5 | 0.5 | 2 | 0 | 0 | 41 | 12 | | Variant 3 | claude-haiku-5-5 | A | 4 | 4 | 0 | 4 | 1 | 1 | 1 | 0 | 0 | 0 | 35 | 12 | | Pooled descriptive | claude-haiku-5-5 | B | 12 | 12 | 0 | 12 | 1 | 1 | 1 | 0 | 0 | 0 | 99 | 12 | | Variant 1 | claude-haiku-5-5 | B | 4 | 4 | 0 | 4 | 1 | 1 | 1 | 0 | 0 | 0 | 24 | 12 | | Variant 2 | claude-haiku-5-5 | B | 4 | 4 | 0 | 4 | 1 | 1 | 1 | 0 | 0 | 0 | 42 | 12 | | Variant 3 | claude-haiku-5-5 | B | 4 | 4 | 0 | 4 | 1 | 1 | 1 | 0 | 0 | 0 | 33 | 12 | | Pooled descriptive | claude-sonnet-5-5 | A | 12 | 11 | 1 | 9 | 0.8181818181818182 | 0.75 | 0.8333333333333334 | 2 | 0 | 0 | 87 | 12 | | Variant 1 | claude-sonnet-5-5 | A | 4 | 4 | 0 | 4 | 1 | 1 | 1 | 0 | 0 | 0 | 24 | 12 | | Variant 2 | claude-sonnet-5-5 | A | 4 | 3 | 1 | 1 | 0.3333333333333333 | 0.25 | 0.5 | 2 | 0 | 0 | 33 | 12 | | Variant 3 | claude-sonnet-5-5 | A | 4 | 4 | 0 | 4 | 1 | 1 | 1 | 0 | 0 | 0 | 30 | 12 | | Pooled descriptive | claude-sonnet-5-5 | B | 12 | 12 | 0 | 12 | 1 | 1 | 1 | 0 | 0 | 0 | 100 | 12 | | Variant 1 | claude-sonnet-5-5 | B | 4 | 4 | 0 | 4 | 1 | 1 | 1 | 0 | 0 | 0 | 24 | 12 | | Variant 2 | claude-sonnet-5-5 | B | 4 | 4 | 0 | 4 | 1 | 1 | 1 | 0 | 0 | 0 | 44 | 12 | | Variant 3 | claude-sonnet-5-5 | B | 4 | 4 | 0 | 4 | 1 | 1 | 1 | 0 | 0 | 0 | 32 | 12 | Mechanism hypothesis Hypothesis only: on the silent-fault template the first apparently successful service run did not persist, and the actor had to notice through a separate verification and decide to rerun. In some trials an earlier run failed on a missing dependency before that point. In the unguarded arm the inspection response reported the guard as off, which may have led some actors to read the missing persistence as an unresolved guard problem and stop instead of rerunning. In the guarded arm the inspection reported the guard on, which may have supported a rerun. This is a possible awareness effect on the rerun decision, not a gate-enforcement effect, and it is not tested here. Negative or equivalent cases - The first and third templates show equivalent completed outcomes in both arms for both actor models, with no failed stops and no protected-state failures. - On the second template the unguarded arm had failed stops for both actor models, and the guarded arm did not, a descriptive counterexample to any claim of equal behavior that is not attributable to gate refusals because no gate opportunity occurred. - Successful attempts on the faulted templates confirmed persistence through a separate verification, and recovery there required a rerun; on the other template persistence occurred at the run and verification only confirmed it afterward. Where actors stopped after a non-persisting run, the attempt failed without protected-state damage. Confounds - The operation cap was identical across all cells and above every floor, so cap exhaustion does not explain differences; no cap-limited cell exists. - The actor models differ greatly in known cost per token, so cost is not comparable across models and says nothing about efficiency of the policy. - One held trial for the second actor model has no scored outcome and its usage is not zero-cost evidence; the bounds on that cell reflect this. - Operation totals differed slightly between arms, partly from extra read-back steps; since policy text was identical, this is attributed to guard-state disclosure and actor behavior, not a measured benefit. Limitations - Task identity, fault type, initial readiness and horizon are confounded with one another, and repeated attempts share a template and are not independent. - The guard state is disclosed through the inspection response and tool description, so awareness is confounded with write behavior and cannot be separated here. - A composite success difference would partly follow by construction from the guard design, and no refusal event occurred here. - Stopping without success is not an explicit success claim; success claims are unmeasured. - Same-operator models are not independent reproduction, and any model-by-condition pattern is exploratory. - This is one independently reviewed partition; conclusions apply only to this synthetic mechanism and do not imply any benchmark improvement, causal general strategy benefit, prevalence or inference latency. - Pooled rows are descriptive only and primary interpretation rests on per template, model and condition cells that each have very few repetitions. - All narrative here is model synthesis and hypothesis rather than external evidence. - Conclusions apply only to a contrived synthetic configuration service with artificial faults. They say nothing about benchmarks, prevalence, latency or general strategy transfer. - No primary cell had a gate opportunity, so the gate comparison is UNKNOWN rather than a null effect. - The descriptive arm difference on the silent-fault template is confounded with several factors: guard-state disclosure, template identity, fault type, initial readiness, and repetitions that share a template. - The conclusion sentence on the held trial could be read narrowly. The negative-case list clarifies that failed stops occurred for both actor models. - Explicit success claims were not collected, so success-claim accuracy remains unmeasured. Failed stops are not success claims. - Held trials have no scored outcome, and their known usage is not zero-cost evidence. - The two actor models share one operator, and this review is same-operator model synthesis. It is not external evidence or independent reproduction. - Only this bounded correction was reviewed, and no further automatic correction follows. Unknowns - Whether the guarded arm would show any effect when a malformed write actually occurs. - How actors interpreted the designed one-time silent fault and what drove the decision to rerun or stop, including any role of the disclosed guard state. - Whether the unguarded-arm failed stops reflect actor reasoning about the guard flag or chance variation across few repetitions. - Whether any pattern generalizes beyond this contrived service. Bounded recommendation Treat the gate comparison as unknown. Before drawing any conclusion, add templates in which a malformed write is plausible so secondary gate opportunities exist, and separate guard-state disclosure from enforcement in a follow-up synthetic design. Source motivation These frozen sources motivate the comparison; they are not evidence that this synthetic intervention improves real benchmark outcomes. - https://arxiv.org/html/2601.11868v1 - https://arxiv.org/html/2405.15793v3 - https://arxiv.org/html/2506.07982v1
