CALM: Conflict-Aware Lifecycle Memory Governance for Long-Horizon Language Agents

CALM is a conflict-aware lifecycle memory governance framework for long-horizon language agents. It turns records into evidence-grounded memory cells, updates their validity and lifecycle states from support, conflict and dependency signals, and admits evidence at query time through training-free or learned gating based on temporal applicability. It beats baselines on LongMemEval-S and LoCoMo with Qwen and GPT backbones, and keeping superseded records helps earlier-state reasoning.

Perceiving and Predicting Dynamic Sports: Spatiotemporal Intelligence in Vision Models for Egocentric Tennis Video

This paper presents an annotated egocentric tennis dataset (egocentric video synced with five allocentric views, global positions, contact times, stroke types) and evaluates image encoders, video encoders and vision-language models on seven prediction tasks. Best models reach 0.14 m player and 0.54 m ball localization error and 0.14 s contact-time error. Depth input helps 3D ball localization, and longer histories do not help forecasting. A conditional diffusion model generates whole-body tennis motion in real time.

Explaining Navigation Decisions: Stage-Aware Visual Attribution for Vision-Language Navigation

A stage-aware visual attribution framework for Vision-Language Navigation (VLN) that explains a robot's action choices. It identifies "instruction-stage insensitivity", where existing explainers give similar outputs across navigation stages. The method builds action-conditioned temporal instruction-visual attributions, aggregates relevant historical evidence by stage, and applies an instruction-guided spatial filter. It improves attribution quality across several VLN policies and benchmarks, helps diagnose failure cases, and was tested on a Unitree G1 robot.

RingTrace: Model-Free Spatio-Temporal Detection and Core Attribution for Cache Side-Channels

RingTrace is a monitoring framework that detects Flush+Reload cache side-channel attacks by combining per-core cache-miss counters with slice activity across uncore CBoxes. Its Joint Spatio-Temporal Attribution (JSTA) builds a joint-activity matrix without model training: the largest entry is the screening score and row sums point to a candidate core. The authors report detection before secret leakage, fewer false alarms under heavy memory load, and negligible runtime overhead on commodity processors.

RepProbe: Can Video Language Models Count Repeated Actions? A Diagnostic Benchmark

RepProbe is a benchmark of 42K real and synthetic video clips with exactly 1–20 complete action repetitions, controlling for clip position, temporal coverage and duration. Video language models' counting accuracy collapses at high counts, and this is not explained by frame sampling alone. Linear probes on final-layer representations show count information stays linearly decodable even when the model's answer is wrong, so the failure arises at the output stage, where answers cluster on a few preferred numbers.

Plan-Bench is a benchmark of 699 curated samples across 16 subclasses and three dimensions. It tests whether vision-language models can reason over spatial and temporal information and produce multi-step plans under constraints for embodied tasks, with action execution isolated out. Across 28 VLMs the best model reaches only 75.0% accuracy. Scaling generally helps, and larger models look more promising as high-level planners. Code and benchmark are released.

OmniCompass: A Holistic Benchmark for Omni-Modal Video Grounding and Understanding

OmniCompass is a manually annotated benchmark for video grounding and understanding with two tracks: OmniCompass-VL (820 videos, 2,460 instances; vision-language models) and OmniCompass-AV (240 videos, 720 instances; joint audio-visual evidence for omni-modal models). Each track covers temporal grounding, spatial grounding and QA across short/medium/long videos, and each instance is run in paired text-only and text+image target specifications. Evaluating 50 MLLMs shows open-source models lag proprietary ones, especially on audio-visual understanding, that precise temporal/spatial grounding remains hard, and that predictions are inconsistent across the paired specifications.

Connected Self Forcing: Beyond Local Learning in Video Autoregression

Connected Self Forcing extends Self Forcing, which trains autoregressive video generators on their own rollouts with KV caching but detaches historical caches and so cuts backward gradients between chunks. It reconnects gradient paths across chunks, passing gradients through generated latents into the computations that produced them, so later predictions can shape how earlier context is generated. Shortcut gradient replay recovers cross-chunk gradients without keeping the full rollout computation graph. Combined with distribution matching distillation, it improves long-horizon visual quality and temporal consistency with no change to inference.

Training Parallel Speculative Draft Models by Directly Minimizing Expected Decoding Rounds

The paper formalizes speculative decoding as a Markov reward process and derives the Expected Decoding Rounds (EDR) objective, a hyperparameter-free training loss equal to the expected number of decoding rounds, addressing cross-round coupling that prior block-local surrogate objectives ignore. It derives an exact temporal-difference gradient for unbiased stochastic optimization and an offline evaluator for comparing drafters on shared rollouts without running speculative decoding. Finetuning the DSpark and DFly drafters with EDR improves mean accepted length and beats prior training objectives across nine benchmarks in math, code, and chat.

Self-correction Optimization for Interleaved Multimodal Generation

This paper introduces Self-Correction Optimization (SCO), a training-free method that improves consistency in interleaved image-text generation from multimodal large language models. SCO treats the classifier-free guidance update as a reference signal and applies minimal corrections under two constraints—a new-event constraint for temporal consistency and a state-preserving constraint for visual-subject coherence—avoiding the computational cost of additional training with augmented data. The authors show improvements on interleaved multimodal generation benchmarks and extend the method to video generation tasks like robot manipulation and long-horizon handcrafting.

EC-RAG: Event Chain Retrieval-Augmented Generation for Long Video Understanding

EC-RAG (Event Chain Retrieval-Augmented Generation) is a training-free framework for long-video question answering that organizes video content into an explicit, temporally ordered "event chain" instead of retrieving isolated frames or snippets. It partitions video into semantically coherent segments, fuses multi-modal signals (speech, text, visual cues) at the event level, and retrieves relevant events from the chain to answer queries, working as a plug-and-play addition to existing large video-language models (LVLMs) without extra training. Evaluated on Video-MME, MLVU, and LongVideoBench, it outperforms frame-level retrieval baselines, showing the value of modeling temporal/event structure for long-video understanding.

Lachesis: Lifetime-Aware KV Cache Placement for Agent Serving across HBM and High-Bandwidth Flash

Lachesis is a lifetime-aware KV cache placement layer for LLM agent serving that sits between the agent harness and the serving engine, deciding whether to write each KV cache segment to HBM or high-bandwidth flash (HBF) based on its expected lifetime. The authors identify temporal, structural, and inter-worker axes along which KV cache lifetime diverges in agentic workloads, and show in trace-driven simulation that lifetime-aware placement extends HBF's write-endurance-limited lifetime by 1.19–3.13x over naive HBM-first placement, reaching 3.3–12.2 device-years. This matters for serving infrastructure as agentic workloads with long-lived, multi-agent context accumulation push memory capacity demands beyond what HBM alone can economically provide.

RMS-AQA is a two-stage spatial audio question answering benchmark for domestic environments, designed to test audio-language models' ability to first ground audible sound events and then perform spatio-temporal reasoning about them. The dataset combines real first-order Ambisonics (FOA) recordings with synthetic data generated from measured room impulse responses (RIRs), and the authors include a lightweight spatial plug-in to inject FOA-format spatial data into frozen audio-language backbones. Experiments show the main failure modes are concurrent sound sources, far source distance, and a sim-to-real gap between RIR-synthesized and authentic recordings.

Prompt Injection Detection for Email Agents Through Attack Chain Modeling

This paper proposes an attack-chain-based detection framework for indirect prompt injection in LLM email assistants, combining a text detector, stage-specific verifiers, rule-based risk signals, and user-intent/action consistency checks scored via a logistic decision policy, rather than treating detection as binary malicious-text classification. Evaluated under random splits, temporal and cross-dataset transfer, and ablations across five binary benchmarks, it achieves a mean F1 of 0.406 versus 0.216 for the best of five existing pretrained detectors, and shows random splits overestimate robustness under distribution shift while training on hard benign (attack-resembling) emails reduces false alarms.

Breakdown of Local Denoising as Semantic Speciation

This paper studies two temporal phenomena in generative model sampling dynamics: a 'speciation window' where a sample commits to a semantic class, and a 'nonlocality window' where local context becomes insufficient for generation. Under a 'common cause' hypothesis — that semantic labels explain correlations between distant tokens — the authors prove the nonlocality window must fall within the speciation window, and identify conditions under which both windows collapse to a single phase-transition point as system size grows, verified analytically in Gaussian mixture models.

STEPQuant is a spatial-temporal post-training quantization framework for the fixed-size recurrent states used by Delta-rule linear attention, which become a memory bottleneck under concurrent serving. It allocates bit precision based on error magnitude and memory lifetime (temporal) and fits per key-row/value-column scales based on state distribution and output impact (spatial), achieving near-FP32 accuracy at a 6-bit budget and beating uniform INT8 at 4-bit. Evaluated on Qwen3.8-27B and Kimi-Linear-48B-A3B-Instruct, and integrated into SGLang with custom GPU kernels, it delivers over 5x recurrent-state compression and up to 68.7% total serving memory reduction.

Rethinking Representations for World-Action Modeling

This paper studies how to design the shared representation space used by world-action models, which jointly learn robot control policies and predict future observations. It finds that neither reconstruction fidelity nor raw pre-trained perceptual features alone yield good policy learning, and proposes ReWAM, built on pre-trained DINO features with a Temporal Representation Bottleneck and Action-Grounded Representation Shaping that routes only action-loss gradients into the bottleneck so the policy shapes what is encoded while the world model learns its dynamics. Without generative video pre-training, ReWAM reaches 93.6% success on RoboTwin 2.0 and an 8.28% success rate on RoboDojo using roughly 600 hours of embodied pre-training data.

On a new 35-take benchmark (using SAM-3D-Body pseudo-ground-truth labels), the gated model achieves 69.4mm error on clean data and remains most robust across simulated bias, drift, and dropout faults, automatically suppressing biased firmware-fused foot-orientation channels without test-time supervision (dropout detection AUROC 0.92-0.999). It is compared against a fine-tuned HMD-Poser baseline, which is more accurate on clean data (64.4mm) but degrades far more under worst-case faults (+16.1mm vs +3.5mm).

The work argues for embodied, tangible interaction as an alternative mode of explainable AI that foregrounds the generative process itself rather than final outputs.

Temporal Self-Distillation: Learning Visual State Tracking in Videos Without Supervision

S³T (Self-Supervised Self-Distillation over Time) is a self-supervised framework for continuous video state tracking that trains a sparse-view student to match the next-token distribution of a denser-view teacher generated from the same clip and same model weights, requiring no labels, separate teacher model, or reward signal. Applied to LLaVA-OneVision-2-8B, it improves VSTAT accuracy by up to +2.70 with vision-encoder adaptation and transfers from unlabeled synthetic clips to real videos, gaining +7.95 on VSTAT-YouTube and +4.50 on MVBench Action Count.

galyarder-security

galyarder-security (formerly Shannon Proxy) is a Docker/Temporal-based auditing layer that intercepts model SDK calls (Anthropic, Groq, local Ollama, etc.) and routes them through a local proxy on port 8317 rather than direct cloud endpoints, giving operators visibility into and control over what autonomous coding/tool-using agents execute. It runs structured "security sweep" and threat-modeling workflows against a target repo (`./shannon start`) and includes deterministic cleanup routines (`./shannon cleanup`) to remove agent-generated scripts and execution residue and prevent workspace pollution/exposure. It targets a threat model broader than chat-based prompt injection: agent tool-execution drift, dependency supply-chain issues, and unverified code paths in "agentic company" shell-access workflows.

The Masked Namespace Vulnerability In Temporal CVE-2025-14986 | depthfirst

CVE-2025-14986 is an identity-binding flaw in Temporal's ExecuteMultiOperation endpoint. The outer request was authorized for one namespace, but inner StartWorkflow operations carried a different namespace that the server used for policy and schema preparation while persisting under the authorized one. The post shows the Go code, two exploits (cross-tenant schema access and policy bypass), and the v1.27 fix, with timeline December 2025 to January 2026.

Practical Temporal Proximity in KQL

A technical KQL deep-dive on detecting hands-on-keyboard attacker activity by correlating multiple suspicious process executions (route.exe, quser.exe, curl.exe, setspn.exe, klist.exe) within a time window on the same device. The author explains why bin()/bin_at() bucketing and Near-Real-Time (NRT) analytic rules are unreliable for temporal-proximity detections, then walks through using the row_window_session() window function with MaxDistanceFromFirst, MaxDistanceBetweenNeighbors, and a Restart expression to build accurate session-based correlation across DeviceProcessEvents in Microsoft Defender XDR.
