+#+TITLE: PSF Core: Literate Implementation
+#+ID: psf-core-implementation
+#+PROPERTY: header-args :tangle psf-core.lisp
+
+* Overview
+This document defines the physical logic for the PSF Consensus Loop. It implements the interfaces defined in [[file:../PROTOCOL.org][PROTOCOL.org]].
+
+* Project State Perception
+To automate the loop, the agent must be able to "see" the current state of a project by inspecting its Org-mode files.

+#+begin_src lisp
+(in-package :org-agent)

+#+end_src
+
+* Chaos Gauntlet
+The Chaos Gauntlet is the Foundry's defensive layer. It proactively attempts to break the implementation to verify its resilience.
