  • Temporal Knowledge Graphs in Production RAG: Bitemporal Schemas, Dynamic Entity Resolution, and Point-in-Time Context Retrieval

    Temporal Knowledge Graphs in Production RAG: Bitemporal Schemas, Dynamic Entity Resolution, and Point-in-Time Context Retrieval Standard Retrieval-Augmented Generation (RAG) pipelines operate on a flat assumption: facts retrieved from a vector database or static knowledge graph are treated as timeless truths. When an enterprise corpus contains documents spanning multiple quarters or years, this timeless representation breaks down. Information changes: executives step down, compliance policies a

  • Ephemeral File Systems for AI Coding Agents: Git Worktrees, Rootless OverlayFS, and Copy-on-Write Isolation

    Autonomous AI coding agents frequently execute arbitrary shell commands, modify source code, install third-party dependencies, and run test suites. Granting an unconstrained agent direct write access to a developer's active working tree creates immediate operational hazards: accidental destruction of untracked files, workspace corruption from speculative refactoring, and state leaks across parallel tasks. Heavyweight virtualization solutions like full virtual machines or freshly initialized con
