Frameworks

Proprietary frameworks for AI agent safety, AI governance, and AI-assisted development. Published by Dipankar Sarkar. Each framework is a battle-tested pattern from production work — not a thought experiment.

Substrate Pattern

A safety architecture for LLM-powered AI agents. The layer below the model that decides what the agent is allowed to do, and what it is not.

Defence in Depth

Kill-switch architecture and circuit breakers for AI agents. Multiple independent layers of safety, each one tested against the others.

Tiered Governance Model

A 4-tier AI governance model (T0-T3) for banks, insurers, and asset managers. Aligned to NIST AI RMF, ISO/IEC 42001, and the EU AI Act.

Vibes Inside Guardrails

A framework for production-ready AI-assisted development. The vibe-coding pattern, with the guardrails that make it safe to ship in regulated environments.
