Jev System One vs Specialized Sovereign RAG. An Empirical Benchmark
Across 20 measured trials on Apple Silicon MPS, a cloud-hosted decision primitive averaged 457.19ms P50 (381.0ms upstream cloud floor) and consumed 453 tokens before retrieval began. A co-hosted sovereign classifier completed the same routing in 0.23ms with zero tokens.
Why Telling an LLM Not to Look Guarantees It Will
Vals AI's BioMysteryBench audit confirms what the attention mechanism already predicts: instructing a model to ignore data forces it to attend to that data. The fix is physical, not linguistic.
The 51.4% Problem: Why Post-Hoc Validation Fails Legal RAG Governance
Why post-hoc validation causes a 51.4% abstention rate in legal RAG governance, and how in-flight sentence-level NLI verification solves the hallucination tax.
legal-rag-router: Deterministic Citation Routing for UK Legal RAG, Measured Against Gemini, Jev and Laya
An open-source router that binds a legal RAG query to the cited UK provision before vector search. Blind sealed run, 29 September 2026: 0 of 1,897 real citations bound to the wrong instrument. Gemini 3.8 Flash (high) routing on its own, 1 October 2026: 102 of 1,897.
The EU AI Act & Legal RAG: Why 'Approve' Buttons Fail Compliance Audits and How to Build Deterministic Human Oversight
From Article 14 Human Oversight to Entity Masking Engines: Architectural blueprints for engineering auditable, deterministic legal AI under strict EU/UK regulatory regimes.
Decoupling POSIX from Object Storage: The JuiceFS Architecture
Object storage is flat, but applications expect directories. A teardown of how JuiceFS splits the storage path, mitigates single-thread page fault traps in Redis, and implements 4MB chunk retrieval without local cache bloat.
When Safari Becomes the Silent Enemy
Spent days implementing video sessions. AWS failed. LiveKit crashed. Every major solution worked everywhere—except iOS Safari. The problem wasn't the code. It was the platform's own interpretation of the standards. One architecture handled it; the others did not.
Context Engineering: The Hidden Art of Building with AI
Communication shapes better code than syntax ever could. On specification design, AI orchestration, and the emerging role that synthesizes systems rather than writes them.
