+## 🔄 The New Fleet Topology (Hub & Spoke)
+
+As defined in the `OpenSIN-overview` SSOT, the OpenSIN A2A fleet uses a strict **Hub & Spoke** model to prevent N^2 communication chaos.

+    User[Operator / Telegram] -->|Task| TeamManager[Team-SIN-* Orchestrator];
+    Hermes[SIN-Hermes Global Router] -->|Payload| TeamManager;
+    
+    TeamManager -->|Consults| Lexicon[(Team Lexicon / RAG)];
+    TeamManager -->|Delegate| Workers[A2A-SIN-* Worker Agents];
+    Workers -->|Result| TeamManager;
+    
+    TeamManager -->|Aggregate & Respond| Hermes;
+    TeamManager -->|Aggregate & Respond| User;
+```
+
+**Key Rules:**
+1. **Workers are Silent:** `A2A-SIN-*` worker agents NEVER communicate with workers from other teams. They only accept tasks from their designated `Team-SIN-*` manager.
+2. **Team Managers Orchestrate:** Only `Team-SIN-*` agents possess the `TELEGRAM_BOT_TOKEN` to communicate with humans.

+## 🚫 Technology Sovereignty Mandate (Browser Automation)
+
+**STRICTLY ENFORCED:**
+- **Playwright**, **Puppeteer**, **Selenium**, and **Camoufox** are **PERMANENTLY BANNED** across the entire OpenSIN-AI organization.
+- They are easily detected by Cloudflare, trigger massive bot-detection red flags, and lack true native stealth.
+
+**THE OPENSIN STANDARD:**
+All A2A Agents MUST use the **OpenSIN-Bridge Chrome Extension** via the MCP WebSocket Server. 
+Alternatively, if OS-level isolation is absolutely necessary, use `webauto-nodriver-mcp` (which wraps `nodriver`).

+# 🏷️ Naming Conventions & SSOT
+
+## The Ultimate SSOT
+Before modifying any code or reading further, you must be aware of the **[OpenSIN-overview](https://github.com/OpenSIN-AI/OpenSIN-overview)** repository. It is the Single Source of Truth for the entire organization.
+
+## Strict Naming Schema
+To prevent architectural chaos, every repository in the OpenSIN-AI organization **MUST** follow this strict naming schema:
+
+`[Type]-SIN-[Name]`
+
+### Valid Types:
+- `Team-SIN-*` (Orchestrators, Hubs, Managers. E.g., `Team-SIN-Legal`)
+- `A2A-SIN-*` (Worker Agents that execute tasks. E.g., `A2A-SIN-ClaimWriter`)
+- `MCP-SIN-*` (Model Context Protocol Servers / Tools. E.g., `MCP-SIN-Browser`)
+- `CLI-SIN-*` (Command Line Interfaces / Terminals. E.g., `CLI-SIN-Code`)
+- `Template-SIN-*` (Blueprints for the forge scripts)
