Character-Name Concentration in LLM Fiction: Measuring Displacement and Mitigating RepetitionSpeculative naming is a fine-tuning-free method that cuts character-name repetition in LLM fiction. It adapts draft-verify-reject from speculative decoding to names, using verbalized sampling and a SlopTracker that combines a per-model fingerprint with a runtime counter. Across 20 LLMs and 44,782 stories in four languages, it cut Slop Ratio by 95% and mean collision probability from 7.3% to 0.4%. Static banlists only displaced the concentration to emergent names.

StripWake is a projector-only backdoor attack on large vision-language models. It stays dormant under full-token inference and activates when visual-token compression prunes the context around a trigger (context stripping). On LLaVA-1.5-7B across nine unseen compressors, it reaches 0.4% full-token attack success rate and 94.0%-99.7% compressed ASR on five primary compressors, with no CIDEr loss. Training aligns early visual attention with a frozen benign teacher.

Vision-Language Models Are Joint Denoisers in Robotic Action GenerationJADE (Joint Action DEnoiser) is a diffusion-based vision-language-action architecture in which the VLM reads the current noisy action latents together with images and instructions at every denoising step, and guides the action expert through gated cross-attention. The VLM is also trained to recover clean action latents, and an adaptive step-size schedule cuts sampling steps. On RoboDojo it averages 12.67% success, the highest among Ο0.5-based methods, and it adds 20.8 points over Ο0.5 on four real bimanual tasks.

TRIAGE: Reliability- and Load-Conditioned Escalation for Two-Tier LLM Serving with a Semantic Evidence JudgeTRIAGE is a two-tier LLM serving scheme that escalates requests from a small model to a large one based on a post-generation reliability state and a load-dependent GPU price. On one A40 serving Qwen2.5-7B and 32B (AWQ) under vLLM, escalation cost rose 21.9x from 1 to 10 requests/s. A pre-registered claim that the reliability state detects corrupted evidence (AUROC 0.70 or higher) failed at 0.571. A semantic evidence judge raised detection to 0.846. The 7B to 32B pair showed only a +2.88 pp held-out gap, so the allocator declined to escalate.

CivicBench: A Benchmark and Memory Framework for Web-Based Civic Data AnalyticsCivicBench is a 400-task benchmark over four cities and two years that freezes civic Web data (service requests, boundaries, weather, demographics) into reproducible bundles. Executable contracts score computation, source linkage, coverage, scope, qualified answers and refusal. The paper also proposes Task-State Memory (TSM), which compiles tool observations into typed assertions and reconciles records only within compatible scopes. Eight of nine model pairs show positive mean-score gains with bootstrap intervals excluding zero.

Constraint Dependency Graph Retrieval for Compliance Detection on Long SKILL DocumentsSkillCDG is a compliance detection framework that turns each long SKILL document (an enterprise SOP followed by LLM agents) into a constraint dependency graph. Atomic rules are nodes tied to source text spans, and mandatory prerequisites are the only edges. Policy-generated keywords seed rules, and their dependency closure fills the small auditor's context budget. Retrieval is trained with GRPO and selective on-policy distillation. It beats full-document and retrieval baselines on three enterprise datasets and two public benchmarks.

It projects retrieval alignments into continuous soft tokens so the generator receives retriever-side signals, and adds a soft orthogonality objective against rank collapse in decoder-only models. The abstract reports gains in retrieval and question answering over state-of-the-art baselines, without numbers.

On the Fundamental Limits of Prefill-Based Decoding Length PredictionThis paper derives bounds on predicting an LLM's decode length from prefill-phase hidden states, a primitive for inference scheduling. It models decoding as a stopped stochastic process, giving per-prompt normality and an affine variance law Ο=Ξ±ΞΌ+b. Predictors (MLP, EGTP, FiLM, soft-label, Mixture-of-Experts) converge near the bound, so system error dominates model error. It proposes fixing model, data and sampling in benchmarks and reporting relative-error metrics.

Efficient Scalable Oversight via RewindingRewindable interactive proofs (RIPs) are a new model of relativizing interactive proofs for scalable oversight, in which a weak verifier can rewind an AI prover to an earlier saved state. The paper builds an RIP for computations robust to changes in a small fraction of oracle answers. The honest prover runs in linear time, the verifier runs in nearly linear time in the input length after one-time preprocessing, and no cryptography is used. A preliminary MNIST experiment shows an RIP can be faster than a deployed proof system.
