A paired oversight experiment found that wider action windows increased catches and false rejections together; one or two actions carried the clearest signal.

## 1. The Longer Review Rejected More and Distinguished Less {#mp-2026-08-26-001}

**Dek:** A paired oversight experiment found that wider action windows increased catches and false rejections together; one or two actions carried the clearest signal.

The twin-prefix framework holds a plan fixed while comparing a clean prefix with a version that differs by one environment-accepted error. Six language-model judges reviewed those pairs at five nested lengths. Longer windows caught more bad plans, but false rejection rose in lockstep, so preregistered informedness peaked at one or two actions in both tested domains. Replaying observations that the longer prompt had withheld recovered much of the lost discrimination. The result does not say that short review is universally safest; it says a safety case must name its verification unit and measure clean-plan rejection alongside catch rate.

**Dek:** NeuronGuard trains refusal behavior to survive deliberate neuron ablation, targeting jailbreaks and post-deployment pruning through one shared weakness.

NeuronGuard periodically identifies safety-critical neurons with per-layer classifiers, then trains the model to preserve refusal behavior while some of those neurons are deliberately ablated. KL regularization keeps output distributions consistent, while randomized gradient projection manages conflicts with task learning. Across three models, six attack strategies and multimodal tests, the authors report near-zero attack success while maintaining task accuracy, including under white-box adaptive attacks, and give an upper-bound argument for reduced attack success. Those are controlled experimental results on the tested settings, not proof that redistributed signals make every model or deployment universally safe.

**Dek:** Calibration-Preserving Pruning treats compression as an efficiency problem after split conformal prediction fixes the reliability contract.

At 50 percent sparsity on DBpedia-14, CPP-SparseGPT reduced mean prediction-set size from 10.1 to 8.6 while accuracy moved from 0.347 to 0.366. It produced smaller sets in 13 of 15 dataset-sparsity cells, but matched controls showed generic supervised gradients explain much of the gain; the claims remain limited to reliability-sensitive classification.

**Dek:** SPIDER4TianoCore reports downstream patch status with reviewable evidence instead of claiming that a match proves safe propagation.

On 20 prepared target-CVE pairs from eight public EDK II repositories, the analyzers found 10 high-confidence pre-patch matches, four high-confidence post-patch matches and abstained on six. None of the confident classifications disagreed with recorded manual labels, but the authors frame this as preliminary evidence generation for prepared targets, not general downstream accuracy.

The benchmark contains 5,667 multiple-choice questions, 22,614 image instances and 135,684 translations across six languages. Tested audio and multimodal models showed substantial multilingual and cross-modal gaps; a lightweight fusion model fine-tuned on the training split improved up to 12.4 percent in multilingual tests and 21.7 percent in multimodal evaluation over its stated baseline.

**Dek:** TrustShift models an MCP server that behaves honestly through a conditioning window before switching to a malicious payload.

Across four production-style domains and frontier proprietary and open-weight models, the staged attacks reached a reported 69.5 percent mean success rate. A transport-boundary defense learned behavioral baselines during clean windows and reduced that figure to 42.7 percent, leaving meaningful residual risk and showing why static deployment checks cannot see a later server-controlled defection.

Across 32,000 selected Big Five items, broad semantic agreement concealed large local changes in evidence and survival. Every evaluable form filled all content cells, yet inclusive primary forms from different embedding configurations shared a median of only six of 40 items, making the computational evaluator part of measurement design rather than neutral plumbing.

**Dek:** A seven-year Shopify marketplace panel finds that governance and entry conditions mattered more than simply arriving first.

The study combines a 24,826-app snapshot with weekly tracking of 7,708 apps across 366 weeks. Later entrants grew faster in 88 percent of 50 analyzed categories, while public data from an app's first six months predicted two-year exit with cross-validated AUC above 0.8. The measurements describe Shopify's marketplace and detection method, not every software platform.

**Dek:** A resilience suite separates rebound, stability and graceful extensibility from end-of-task success.

Across 400 household tasks and 10 embodied-agent systems, the process metrics exposed recovery-cost differences of 25.2 among episodes that all ended successfully, along with instability and task-family degradation. Metric-guided changes reduced recovery cost and improved stability and extensibility completion, while also revealing tradeoffs among those properties.

**Dek:** Pipeline-native transformers co-design dependency graphs with a stage-major runtime for bandwidth-bound decoding.

One tested architecture halved critical-path weight bandwidth from 9.00 to 4.50 MB per token while staying within 0.24 perplexity of the best candidate. On a 30.9-billion-parameter mixture-of-experts model, the cflow runtime reported 5.94 tokens per second on 32 Ice Lake vCPUs; the authors also report one design claim refuted and another inconclusive.

The system generates API-level emulators for AWS and GCP services, then uses real-cloud behavior to test, repair and align them. The authors report higher coverage and accuracy than LocalStack in their evaluation, but the comparison is confined to the selected services and harness rather than every behavior in either cloud platform.

The policy combines sharper reward separation, a virtual child that estimates the value of branching and quality-conditioned expansion.

Retrieval-augmented models consistently narrowed, but did not close, the performance gap between high- and low-frequency lexical items across syntactic phenomena and training scales. Semantic similarity alone offered little benefit; structural information was the useful retrieval signal.

Structural retrieval helped language models judge syntactic contrasts containing low-frequency words.

**Dek:** PolyHuman tests functional equivalence across human-written C++, Java and Python.

Models increasingly mislabeled non-equivalent programs as equivalent as difficulty rose, and the strongest tested model showed Python sensitivity plus run-to-run instability under identical settings. Manual analysis of 81 systematic disagreements found partial reliance on similarity cues rather than reliable semantic judgment.

**Dek:** A profiled simulator places tensor parallelism and KV compression on one cost-latency chart.

Across two model sizes and three GPU types, compression was 1.20 to 2.00 times cheaper in every comparable memory-relief configuration. Above roughly 36 billion parameters on an 80 GB device, weights—not cache—became the binding constraint, making tensor parallelism an entry requirement despite higher cost.
