-## Overview
-
-Purple Team Code Workbench is an AI-assisted cybersecurity experimentation environment designed for defensive researchers, purple-team operators, and security engineers. The platform combines LLM-driven code generation, workflow prototyping, and adversarial simulation capabilities inside a lightweight Streamlit interface.
-
-The platform focuses on:
-
-- Authorized assessment workflows
-- Defensive and adversarial simulation support
-- Code generation for security operations
-- Evidence handling and finding management
-- Prompt-assisted workflow acceleration
-- Report artifact generation
-- Research and analysis augmentation
-
-The system is intentionally structured around controlled workflows rather than unrestricted autonomous execution.
-
----
-
-## Why Purple Team?
-
-Purple-team methodology combines offensive security simulation with defensive validation and detection engineering.
-
-This workbench is designed to support collaborative workflows between:
-
-- security researchers
-- defenders
-- detection engineers
-- SOC analysts
-- incident responders
-- application security teams
-
-The focus is operational learning, validation, and resilience improvement rather than isolated offensive capability.
-
----
-
-## Safety & Intended Use
-
-Purple Team Code Workbench is intended for:
-
-- Authorized security testing
-- Defensive security research
-- Secure software experimentation
-- Educational cybersecurity workflows
-- Purple-team simulation and analysis
-
-This project is not intended for unauthorized access, malware deployment, credential theft, persistence mechanisms, or destructive operations.
-
-Users are responsible for complying with applicable laws, organizational policies, and authorization requirements.
-
----
-
-## Non-Goals
-
-This project is not intended to provide:
-
-- autonomous offensive operations
-- malware automation
-- persistence tooling
-- uncontrolled exploitation workflows
-- credential harvesting systems
-
----
-
-## Model Roles
-
-| Model | Purpose |
-|---|---|
-| Gemma-4-E4B-Uncensored | Experimental reasoning and adversarial simulation support |
-| DeepHat-V1-7B | Security-oriented coding and workflow assistance |
-| Llama 3 8B Instruct | General reasoning and structured instruction following |
-
----
-
-## Runtime Environment
-
-- Python 3.11
-- Streamlit 1.57.0
-- Transformers-based inference stack
-- CPU-compatible deployment
-- Optional GPU acceleration
-
----
-
-## Core Design Principles
-
-### Scope-First Architecture
-
-Every workflow begins with explicit authorization and target definition.
-
-The system is designed to reduce:
-
-- accidental scope drift
-- unsafe automation
-- uncontrolled execution paths
-- ambiguous operational state
-
----
-
-### Human-in-the-Loop Control
-
-The workbench assists analysts and engineers rather than replacing operational judgment.
-
-Generation ≠ execution.
-
-All generated output should be reviewed before use.
-
----
-
-### Evidence-Centric Workflow
-
-Outputs are treated as operational artifacts:
-
-- findings
-- prompts
-- code snippets
-- reports
-- remediation notes
-- validation records
-
-The system emphasizes traceability and reproducibility over “magic AI behavior.”
-
-A tragically rare design choice in 2026.
-
----
-
-## Features
-
-### Current Capabilities
-
-- Streamlit-based UI
-- Scope-gated workflow controls
-- Security code generation surface
-- Passive recon helpers
-- Structured findings management
-- Markdown report export
-- Multi-model workflow support
-- Hugging Face Space deployment compatibility
-
----
-
-### Planned Capabilities
-
-- Workflow templates
-- Prompt chaining
-- Agent orchestration
-- Typed finding schemas
-- Multi-provider inference routing
-- Local LLM runtime support
-- Evidence graphing
-- Drift-aware execution state
-- Report diff/version tracking
-- LangGraph integration
-- MCP-compatible tool surfaces
-
----
-
-## Supported Models
-
-Current configured models:
-
-| Model | Purpose |
-|---|---|
-| HauhauCS/Gemma-4-E4B-Uncensored-HauhauCS-Aggressive | Experimental coding and reasoning |
-| DeepHat/DeepHat-V1-7B | Security-oriented generation workflows |
-| Meta-Llama-3-8B-Instruct | General-purpose assistant workflows |
-
-Model availability depends on provider access and deployment configuration.

+## Safety posture
 
-Inspired by structured operational engineering, purple-team methodology, and the stubborn belief that security tooling should behave like systems engineering rather than ritual magic.
+The app intentionally avoids autonomous offensive execution. It is a scope-gated workflow, findings, evidence, and report workspace for authorized defensive/purple-team work.
