Why Is do-calculus Not Enough? New Progress in Research on Universal Identifiability of Causal Effects
New progress in causal inference research: the paper rigorously formalizes the definition of do-calculus completeness, proving that it remains complete for classical ID and gID problems but is no longer complete for universal identifiability (uID), revealing a possible reason why uID has long remained unsolved.
ResQAdam: A Residual-Preserving Adaptive Optimizer That Substantially Cuts QAT Memory Overhead
By preserving the sign of QAT momentum residuals, ResQAdam achieves near-AdamW accuracy in a low-rank framework while cutting optimizer state memory by 71%–74%, with under 2% throughput loss.
From Procedures to Permissions: How Agent Skills Teach Subagents Precise Authorization
In multi-agent collaboration, which tools and workspace permissions should subagents receive? Research extracts authorization supervision signals from Agent Skills' procedural knowledge, significantly improving permission precision and task success rate on ClawArena-Team.
Language Models Under Self-Training: Richer Vocabulary, Yet Lower Entropy?
A nine-generation GPT-2 self-training experiment reveals: word types drop 24% while collision entropy rises 0.91 bits, with ordered Renyi crossings robust, challenging single-metric model-collapse assessment.
Domain Fine-Tuning Erodes AI Safety Guardrails: A Paired Audit of Biomedical LLMs
A paired audit comparing 25 biomedical domain fine-tuned LLMs with 11 base checkpoints finds knowledge-centric abstention dropped from 8.3% to 4.2%, with 21 of 25 pairs declining, revealing that domain fine-tuning may erode AI safety guardrails.
SteerGR: Sparse Autoencoders Enable Controllable Game Recommendations
SteerGR uses sparse autoencoders to enable concept-level control in generative recommendation, steering results toward or away from target concepts via a three-stage framework without model retraining, validated on a real game dataset.
JCMC: Reshaping Persistent Memory Systems with Jacobian-Causal Control
The paper proposes Jacobian-causal memory control (JCMC), using Jacobian impact signatures to control persistent memory interventions, screening target effects and side-effect budgets in a behavioral measurement space, and supporting a predict-observe-rollback loop. The article reviews its mechanism, theoretical guarantees, and falsifiable evaluation protocol.

Vercel AI SDK Sandbox Tool Releases 1.0.177 Patch Update
Vercel AI SDK releases @ai-sdk/sandbox-vercel@1.0.177 patch, updating @ai-sdk/harness in sync. We analyze what this patch signals, the sandbox's role in the AI SDK architecture, and how developers should handle such small version upgrades.
The LLM Verbosity Problem: Beyond Truncation, Where Are the Limits of Semantic Preservation?
How to solve LLM output verbosity? This article interprets new research: entropy-gating processors are actually truncation; ELIDE outperforms truncation but 59% of deletions are harmful, revealing the limits of semantic preservation and training-free methods.
Phantom Consensus in Multi-Agent LLMs: How Social Reasoning Leads to Collective Decision Failures
Multi-agent LLM systems can exhibit "phantom consensus": models change public decisions under ambiguous social signals and misjudge others' private judgments. PHANTOM-Bench reveals public accuracy drops by up to 47.8 points, and transparency can repair most failures.
