# Daily AI Operator Briefing — 2026-03-21## Executive Summary- ByteDance's OpenViking is a filesystem-based context database for AI agents — L0/L1/L2 tiered retrieval, observable trajectory, session self-iteration; strong fit for PIBP, Ted Dashboard, and OpenClaw agent builds- Cursor Composer 2.0 is built on Kimi K2.5 with no attribution — signals a growing transparency problem in commercial AI tooling; operators should audit model provenance in tools they depend on- Qwen 3.5 397B is now runnable locally via Apple's LLM in a Flash technique at 5.5 tokens/sec — the ceiling on local model size has shifted materially- Prompt injection via retrieval is now confirmed as a real attack vector (Snowflake Cortex); trust boundaries around agent retrieval steps need explicit design attention- Ollama 0.18.2 is out — patches stale model selection and stabilises web search/fetch plugin registration; worth updating if running local search with OpenClaw
