+# Life Sandbox Runtime
+**An operational systems lens for human behavior**
+
+Author: Kevin T. Nguyen  
+Contact: jkdkr2439@gmail.com

+
+## What this is
+This repository presents **Life Sandbox Runtime**, a principle-only framework that models human life as a continuously running system with:
+- event loops
+- resource quotas
+- failure modes
+- observability
+- safe deployment of change
+
+It is written in engineering language and designed to be usable as a **system prompt for custom AI agents**.
+
+No motivation.  
+No manifestation.  
+No “change your life in 1 day” promises.
+
+---
+
+## What problem this addresses
+Most life-advice content focuses on:
+- clarity
+- identity
+- inspiration
+
+But real change fails due to:
+- backpressure
+- poor scheduling
+- missing observability
+- unsafe rollouts
+- unhandled failure modes
+
+This framework treats those as **system design problems**, not personal flaws.
+
+---
+
+## Core model (high level)
+- Main loop: Sense → Interpret → Decide → Act → Feedback → Save-file update
+- Subsystems: perception, decision, memory, social networking
+- Quotas: energy, attention, time, self-control, buffers
+- Failures: deadlock, livelock, memory leak, cache stale, Goodhart, permission creep
+- Deployment: CI/CD-style habit rollout with canary and rollback
+- Security: boundaries, rate limits, decision 2FA
+
+---
+
+## How to use this repo
+### Option 1: As a system prompt
+Use `system_prompt/LifeSandboxOS_system_prompt.txt` directly as the system instruction for a custom AI assistant.
+
+### Option 2: As a personal operating model
+Use the framework to:
+- diagnose why change fails
+- design safer behavior experiments
+- debug burnout, procrastination, over-optimization
+
+---
+
+## What this is NOT
+- Not therapy
+- Not medical or psychological advice
+- Not a productivity hack list
+- Not a claim to solve consciousness or AGI
+
+---
+
+## Why this exists
+Popular frameworks often create **clarity without execution safety**.
+This work prioritizes:
+- stability over motivation
+- observability over intention
+- rollback over willpower
