Opening — Why this matters now Retrieval-Augmented Generation has reached an awkward adolescence. Vector search is fast, scalable, and confidently wrong when questions require structure, multi-hop reasoning, or global context. GraphRAG promised salvation by injecting topology into retrieval — and promptly ran into its own identity crisis: global search is thorough but slow, local search is precise but blind, and most systems oscillate between the two without ever resolving the tension. ...

Opening — Why this matters now Public-sector AI has a credibility problem. Not because it cannot optimize—but because it optimizes too cleanly. In health system planning, decisions are rarely about pure efficiency. They are negotiated compromises shaped by terrain, politics, institutional memory, and hard-earned intuition. Classic optimization methods politely ignore all that. This paper tackles a question many planners quietly ask but rarely formalize: Can we let algorithms optimize without silencing human judgment—and still keep mathematical guarantees intact? ...

Opening — Why this matters now The AI industry has developed an unhealthy obsession with thinking longer. More tokens, deeper chains, bigger context windows—surely that must mean better reasoning. Except, increasingly, it doesn’t. Large Reasoning Models (LRMs) often reason past the point of usefulness, slipping into self-validation loops or overwriting correct answers with unnecessary exploration. This paper proposes a heretical idea in the age of scaling: maybe the model doesn’t need to think more—it needs to know when to stop. ...

Opening — Why this matters now Multi-agent LLM systems are having a moment. Software engineering agents argue with each other, math solvers debate proofs, and code reviewers nitpick outputs like caffeinated interns. The results are often impressive—and painfully expensive. Token budgets explode, latency compounds, and the coordination logic starts to look like an over-managed meeting that should have been an email. ...

Opening — Why this matters now Functional dependency (FD) discovery has quietly become a victim of its own success. Modern algorithms can enumerate everything—and that is precisely the problem. On realistic schemas, exhaustive FD discovery produces hundreds of thousands of valid dependencies, most of which are technically correct and practically useless. Computationally expensive. Cognitively overwhelming. Operationally irrelevant. ...

Opening — Why this matters now Multimodal models have become unnervingly confident readers of documents. Hand them a PDF, a scanned exam paper, or a photographed worksheet, and they will happily extract text, diagrams, and even implied structure. The problem is not what they can read. It is what they refuse to unread. In real classrooms, mathematics exam papers are not pristine artifacts. They are scribbled on, folded, stained, partially photographed, and occasionally vandalized by enthusiastic graders. Yet most document benchmarks still assume a polite world where inputs are complete and legible. This gap matters. An AI system that confidently invents missing math questions is not merely wrong—it is operationally dangerous. ...

Opening — Why this matters now LLMs are increasingly trusted to recommend what we watch, buy, or read. But trust breaks down the moment a regulator, auditor, or policy team asks a simple question: prove that this recommendation followed the rules. Most LLM-driven recommenders cannot answer that question. They can explain themselves fluently, but explanation is not enforcement. In regulated or policy-heavy environments—media platforms, marketplaces, cultural quotas, fairness mandates—that gap is no longer tolerable. ...

Opening — Why this matters now Everyone is chasing longer context windows. Million-token prompts. Endless chat logs. The assumption is simple: if the model can see everything, it will remember correctly. This paper shows why that assumption fails. In long-horizon, goal-driven interactions, errors rarely come from missing information. They come from retrieving the wrong information—facts that are semantically similar but contextually incompatible. Bigger windows amplify the problem. Noise scales faster than relevance. ...

Opening — Why this matters now Architectural studios are quietly changing. Not with robotic arms or parametric scripts, but with prompts. Text-to-image models now sit beside sketchbooks, offering instant massing ideas, stylistic variations, and visual shortcuts that once took hours. The promise is obvious: faster ideation, lower friction, fewer blank pages. The risk is less visible. When creativity is partially outsourced, what happens to confidence, authorship, and cognitive effort? ...

Opening — Why this matters now Genomics QA is no longer a toy problem for language models. It sits at the uncomfortable intersection of messy biological databases, evolving schemas, and questions that cannot be answered from static training data. GeneGPT proved that LLMs could survive here—barely. This paper shows why surviving is not the same as scaling. ...
