Sentinel makes goal drift impossible in AI coding agents through cryptographically verified, continuously validated goal alignment and hierarchical context injection.

Current AI coding agents suffer from cognitive drift and context loss:
- Cognitive Drift: progressive loss of alignment between actions and original intent.
- Context Loss: agents hit token limits, forgetting "North Star" or invariants of project.
- Execution Blindness: agents write code that compiles but violates high-level architectural rules.
Sentinel is a 10-layer cognitive architecture that ensures perfect alignment from initial intent to final execution.
Original Vision (CLAUDE.md v1.0.0): A local cognitive operating system with 6 layers (1-6)
Current Reality: A global distributed intelligence network with 10 layers (1-10)
The project has evolved from a single-node cognitive OS to a worldwide collective intelligence network that shares learnings, detects threats, and reaches consensus across distributed nodes.

Sentinel nodes find each other via Kademlia DHT. They share "Anonymized Patterns" – mathematical abstractions of success that protect your IP while making the entire network smarter.
Critical decisions are no longer made by a single process. Sentinel calculates a quorum of authority:
- Human Authority: 1.0 (The ultimate decider)
- Senior AI Node: 0.8 (Highly aligned history)
- Junior AI Node: 0.3 (Learning/Testing)
If a Sentinel node in the network detects a rogue AI behavior or a corrupted dependency, it broadcasts a signed alert. All connected nodes automatically tighten their guardrails.
⚡ REVOLUTIONARY APPROACH: LLM is used as a supervised creativity engine under Sentinel OS's rigorous quality control.
