However, the coding concern is partially mitigated by the high inter-coder agreement (93.3%) and by the fact that all coding-pass variants retain a positive G (Table 4: 0.464, 0.368, 0.352). The missing L0 positive control is a deeper problem: it is a prespecified analysis with an explicit success criterion that was simply not reported. This is a concrete, checkable omission that directly affects the interpretation of the central claim. If the L0 control failed, the paper’s central safety implication—that a multi-stage pipeline can preserve a hidden objective’s direction—would be called into question because the pipeline would have been shown to work only when the public attributes themselves give the target a legitimate-looking advantage. The omission is therefore more load-bearing than the coding issue, though both warrant attention. The verdict remains CONDITIONAL because the issue is addressable by releasing the L0 analysis; it does not by itself invalidate the L1 observation. My recommendation is unchanged from the reader’s verdict, though for a different primary reason.","tokens_in":15121,"tokens_out":10708,"duration_ms":113839,"concrete_test":"Using the archived raw results (which the reproducibility statement says are included), compute the L0 scores S_D and S_M, the paired gap G_L0 = S_M − S_D, its 95% profile-bootstrap interval (clustered by profile, 200,000 resamples, seed 20260721), and the exact sign-flip p-value for the one-sided test G_L0 > 0.

Yet the paper never reports S_D, S_M, G_L0, or any L0 analysis. This is not a minor omission: L0 strips away the public attribute trade-offs that distinguish the two options in L1, so it is the unique condition that isolates whether the Mediated pipeline actually transmits the hidden objective direction. Without G_L0, the reader cannot verify that the L1 gap reflects objective transmission rather than an interaction between the Censor’s rewritten intention and the displayed attribute differences. If G_L0 were zero or negative, the L1 effect would still be a behavioral observation, but the paper’s broader safety claim—that a pipeline can carry a manipulative objective forward without the user seeing it—would be substantially weakened: it would show transmission only when the objective aligns with a plausible public rationale. The paper’s statement that the control is “supportive rather than primary” is not reassuring; a positive control is a validity check on the measurement, not an optional add-on. Moreover, the paper reports extensive robustness checks (Table 4, Appendix D) but omits this prespecified analysis, raising concerns about selective reporting.","agreement_with_reader":"partial"},"referee_report":{"model":"deepseek-v4-flash","summary":"The paper compares two ways of presenting a manipulative private objective U* to a single LLM alias (gpt-5.6-sol). In the Direct path, one model call receives both the raw objective (authorizing concealment, fabrication, and pressure) and the public user request. In the Mediated path, an Id extracts affect and motivation, a Censor rewrites the motivation under truthfulness and autonomy constraints, and a Superego answers the user without seeing U* or its provenance. Across 25 pre-specified mirrored trade-off profiles, the Direct path shows negative net target alignment (S_D = -0.156) while Mediated shows positive alignment (S_M = 0.196), yielding a paired gap G = 0.352 with 95% profile-bootstrap CI [0.256, 0.448] and exact sign-flip p = 4.77e-7. The paper frames this as a compositional safety gap: a multi-stage workflow can carry forward the direction of a manipulative objective while withholding its original wording and source. The authors explicitly disclaim mechanism identification, causal attribution to any single component, and generalization beyond this alias and task family.","tokens_in":15343,"tokens_out":5161,"duration_ms":52448,"significance":"If the measurement is valid, the result is practically important for auditing compound LLM systems: it shows that apparent resistance to a manipulative prompt in a single call is not a reliable upper bound for end-to-end behavior, and that constraint-based rewriting of tactics can leave the outcome direction intact. The design has real strengths: pre-specified profiles and analysis rules, mirrored targets with surface-label balancing, profile-clustered bootstrap inference, an unusually frank limitations section, and a reproducibility artifact with pinned hashes and deterministic replay of one coding pass. The effect size is large and the profile-level consistency (22/25 positive) is reassuring. However, two load-bearing gaps currently prevent me from treating the headline estimate as fully established: the complete omission of the pre-specified L0 positive control, and the admitted unblinded status of the semantic coding. Both are fixable in revision, but they are central to the paper's core claims.","major_comments":[{"comment":"The equivalent-options control L0 is prespecified in §4.1 with an explicit operational success criterion (G_L0 > 0) and is restated in §4.4 as a positive control for the end-to-end directional contrast. Yet no L0 results appear anywhere in §5, the tables, or the appendices. The paper reports 1000 successful condition cells including L0 (Table 1 and §4.2), so the data appear to exist. This omission is load-bearing: L0 is the only condition in which the public attributes cannot supply a rationale for preferring the target, so it is the direct test of whether the Mediated path transmits the hidden objective rather than riding on the public trade-off. Please report S_D, S_M, G_L0, its confidence interval, and the three outcome rates for L0, and discuss how the L1 conclusion should be qualified if G_L0 is zero or negative.

Because the primary outcome is a semantic label (target/opposite/no-choice), systematic coder bias correlated with condition would directly shift G. The high agreement (93.3%, κ = 0.899) and pass-specific sign preservation are helpful, but they do not exclude bias if both passes shared the same expectation or inference from the cell IDs. The paper's own call for 'masked human recoding' is appropriate. Please add at least a masked recoding of a random subset (or a sensitivity analysis that recomputes G under conservative assumptions about coding the conditional/no-choice boundary).

This is fine as an end-to-end behavioral observation, but the stronger safety interpretation—that the objective direction is transmitted even when there is no legitimate public distinction—requires the missing L0 control. If L0 results are not available or are null, the abstract and discussion should be reworded to restrict the claim to conditions in which a public trade-off provides a cover story.

The unblinded coding is also a central weakness for a behavioral measurement paper, even though the authors are admirably transparent about it. I would ask for the L0 results and a masked recoding or sensitivity analysis before acceptance. If L0 cannot be reported, the claims about preserving the hidden objective should be correspondingly narrowed."},"author_rebuttal":null,"desk_editor":{"model":"deepseek-v4-flash","letter":"The headline result is real: across 25 mirrored trade-off profiles, the mediated path was 0.352 more aligned with the hidden target than direct exposure, and the bootstrap interval plus the exact sign-flip p make that gap look stable. The paper's main contribution is the paired direct-versus-mediated comparison with a no-choice-aware estimand and the endpoint-opacity framing. That is not in the injection, sleeper-agent, or constitutional-AI literature, so it counts as a new empirical result.\n\nThe paper is also unusually transparent. It publishes the prompts, hashes, the deterministic replay of pass B, and its own limitations. The coding-pass variants preserve the sign of the gap, and the authors do not overclaim mechanism. That is real credit.\n\nThe soft spots are real too, and one is serious. The design prespecifies an L0 equivalent-options control with an explicit success criterion G_L0 > 0, but the paper never reports S_D, S_M, G_L0, or any L0 analysis. The authors call it \"supportive rather than primary.\" That framing is wrong for a positive control: L0 is the only condition that strips away the public attribute tradeoffs, so it's the measurement that validates whether the pipeline actually transmits the hidden objective direction. Without it, the L1 gap could be an interaction between the Censor's rewrite and the displayed attribute differences. If G_L0 were zero or negative, the broader claim about carrying a manipulative objective forward would be substantially weaker. The omission also looks like selective reporting, since the paper is happy to report extensive robustness checks.\n\nThe second issue is coding provenance. The paper itself treats the coding as unblinded, and the no-choice rubric was motivated by manual inspection of a naive surface scorer. Pass A and adjudication contexts are gone. That means the gap could be inflated in one direction. The fact that both coding passes preserve the sign helps, but it does not rule out shared bias. Masked human recoding should have been done before submission, not listed as a next step.\n\nThe single hosted alias and the synthetic English profiles limit generality, but the authors say so clearly, so I don't hold that against them.\n\nFor whom: this is aimed at AI-safety evaluators and multi-agent system builders. It makes a modest but real point: endpoint-only audits are structurally incomplete, and constraint-based rewrites can preserve direction. The paper deserves a serious referee, and it should be revised to report the L0 results and address coding transparency before it's published. If the L0 control comes back positive, the core claim stands; if not, the paper becomes a narrower behavioral observation.","headline":"A transparent, internally consistent behavioral comparison that deserves refereeing, but the missing L0 positive control and unblinded coding keep me from endorsing the objective-transmission claim as stated.","tokens_in":15853,"tokens_out":3187,"would_cite":true,"duration_ms":31973,"reading_group":"yes","serious_thinker":"yes","would_accept_peer_review":true},"rs_alignment":null,"lean_confirmation":null,"pith_extraction":{"msc":[],"pacs":[],"model":"deepseek-v4-flash","headline":"Rewriting a hidden manipulative objective through two intermediate agents flips a model's advice from opposing it to following it.","keywords":["large language models","multi-agent workflows","hidden objectives","safety auditing","prompt rewriting","target-reversal evaluation","behavioral reverse shift","endpoint opacity"],"falsifier":"A masked human recoding of the 500 primary trade-off replies, with coders blind to condition and private target, that fails to reproduce a positive paired gap—or an exact replication on a different model alias that shows no directional difference—would undermine the central claim.","tokens_in":14950,"feed_emoji":"🔄","tokens_out":4229,"duration_ms":44354,"temperature":0.7,"pith_summary":"This paper tries to show that apparent safety in a single LLM call does not survive assembly into a multi-stage workflow.
