 #+TITLE: OpenCortex: The Conductor of your Life Stack
 
+#+CAPTION: A neurosymbolic AI agent framework for the 100-year Memex
+#+ATTR_HTML: :width 800
+
 *opencortex* is a minimalist, extensible AI agent framework designed to manage and continuously organize your personal knowledge base. It transforms a static collection of plaintext notes into a live, programmable [[https://en.wikipedia.org/wiki/Memex][Memex]]—an automated, personalized memory system where humans and AI collaborate in the exact same workspace.
 
 * The Problem with Current AI Agents
 
 The current ecosystem of AI agents (typically built in Python or TypeScript) is overwhelmingly built on architectural choices that prioritize rapid prototyping over long-term reliability, security, and self-modification:
 
-1. *The Format Trap (Markdown & JSON):* Most agents force a painful translation layer. Humans write in Markdown, which lacks a strict Abstract Syntax Tree (AST)—a rigorous, nested representation of data that machines need to parse context reliably. Machines, in turn, output JSON, which is hostile for human thought and note-taking. The result is a fractured workspace where the agent's memory and the human's memory are fundamentally incompatible.
-2. *The Language Trap (Python & TypeScript):* Python and TypeScript are fantastic for gluing together APIs, but they are poorly suited for an agent that needs to safely read, write, and execute its own code at runtime. Their underlying structures are complex and opaque, making autonomous self-editing incredibly brittle and dangerous.
-3. *The Probabilistic Trap:* Almost all modern agents rely entirely on /probabilistic/ reasoning. We ask an AI model to guess a shell command or write a Python script, and then blindly pipe that output to a terminal. Without a rigorous, /deterministic/ layer to formally verify the model's proposals before execution, these systems are fundamentally unsafe.

+
+The result is a fractured workspace where the agent's memory and the human's memory are fundamentally incompatible. You cannot see what the agent sees. The agent cannot naturally work with your notes.

+** 2. The Language Trap (Python & TypeScript)
+
+Python and TypeScript are fantastic for gluing together APIs, but they are poorly suited for an agent that needs to safely read, write, and execute its own code at runtime. Their underlying structures are complex and opaque, making autonomous self-editing incredibly brittle and dangerous.
+
+How do you trust an agent to modify its own Python code when Python's AST is so complex that even human programmers need IDEs to navigate it?

+** 3. The Probabilistic Trap

+Almost all modern agents rely entirely on /probabilistic/ reasoning. We ask an AI model to guess a shell command or write a Python script, and then blindly pipe that output to a terminal. Without a rigorous, /deterministic/ layer to formally verify the model's proposals before execution, these systems are fundamentally unsafe.
+
+The model might hallucinate a command. It might output valid syntax that still does something dangerous. Without a deterministic gate, there's nothing between the guess and the terminal.
 
 * The Vision: A Modern, Homoiconic Memex

-** 1. Org-mode: The Universal Language
-Instead of wrestling with Markdown parsers or hiding data in opaque databases, opencortex mandates that *Org-mode is the native AST for both humans and machines.* 
+** Org-mode: The Universal Language
 
-Org-mode is unique because it seamlessly brings together human-readable prose, structured metadata (properties and tags), lifecycle states (TODO/DONE), and executable code blocks into a single plain-text file. The code is the data, and the data is the interface. When the agent "remembers" a fact or schedules a task, it writes an Org headline. You read exactly what the agent reads.

-** 2. Common Lisp: The Engine of Self-Modification
-There is a beautiful irony to opencortex: Lisp was invented in 1958 specifically to achieve Artificial Intelligence, and it has been waiting nearly 70 years for /this exact moment/ in computing history. 
+Org-mode is unique because it seamlessly brings together:
+- Human-readable prose
+- Structured metadata (properties and tags)
+- Lifecycle states (TODO/DONE/PLAN)
+- Executable code blocks
 
-Lisp possesses a unique property called *Homoiconicity*: the primary representation of the program is also a data structure (nested lists) within the language itself. Because Lisp code /is/ Lisp data, it is trivially easy for an AI to generate, manipulate, and safely evaluate new tools at runtime. This makes Lisp the ultimate, un-brittle language for a "self-writing" agent.
+...all in a single plain-text file. The code is the data, and the data is the interface. When the agent "remembers" a fact or schedules a task, it writes an Org headline. You read exactly what the agent reads.
 
-** 3. The Probabilistic-Deterministic Loop
-opencortex does not let AI models touch your system directly. Instead, it splits cognition into two distinct engines:
-- *The Probabilistic Engine (Neural/Dynamic):* Provides semantic understanding and dynamic reasoning. It utilizes a **Dynamic LLM Cascade** (OpenRouter, Ollama, Anthropic) to ensure the agent always has a "brain," falling back to local models if cloud services are unavailable.
-- *The Deterministic Engine (Logic/Safety):* Intercepts LLM proposals and formally verifies them against your security rules (the "Bouncer" pattern) before execution.
+This is not a compromise—it's the design principle. The agent's memory and your memory are the same format, the same file, the same text.

 * Architecture: Thin Harness, Fat Skills
 
-To guarantee long-term stability, opencortex enforces a strict architectural boundary inspired by the "thin harness, fat skills" philosophy.
+To guarantee long-term stability, openCortex enforces a strict architectural boundary inspired by the "thin harness, fat skills" philosophy.
 
 ** The Minimalist Harness
+
 The Lisp microkernel is a thin, unbreakable harness strictly responsible for:
-1. *The Memory:* Maintaining the live graph of your Memex in RAM.
-2. *The Unified Envelope:* A protocol-agnostic communication layer that ensures TUI, CLI, and remote gateways (Signal, Telegram) are treated as equal citizens.
-3. *The Metabolic Cycle:* Moving signals through the Perceive -> Reason -> Act pipeline.
+
+| Layer | Responsibility | Examples |
+|-------|----------------|----------|
+| *Perceive* | Normalize sensory input | CLI parsing, Emacs events, heartbeats |
+| *Reason* | Bridge neural and deterministic | LLM dispatch, response parsing, skill routing |
+| *Act* | Execute approved actions | Shell commands, tool calls, UI output |
+| *Memory* | Live object store | Org-object graph, snapshots, rollback |
+
+What the harness does /not/ contain:
+- Policy rules (those are skills)
+- LLM integrations (those are skills)
+- Domain-specific functionality (those are skills)
 
 ** Literate, Single-File Skills
-In opencortex, a Skill is simply a *single .org file* containing everything: the documentation, the AI instructions, and the deterministic Lisp code. When the system boots, it compiles these skills directly into the live Lisp image.
 
-** The Anatomy: Three Data Stores
-1. *The Linguistic Substrate (The Memex):* A collection of plain-text Org-mode files on your local disk. This is the ultimate Source of Truth. Because it is plaintext, it is human-editable, version-controllable, and platform-independent. In OpenCortex, your notes, tasks, and code aren't just "data"—they are the agent's actual configuration and memory.
-2. *The Lisp Memory (RAM):* A live, homoiconic graph of Lisp objects. Upon boot, OpenCortex ingests your Memex files and transforms them into a high-performance in-memory graph. 
-   - *Why RAM?* Traditional databases require expensive joins and context-switching to traverse complex associations. By keeping the entire graph in RAM, OpenCortex can perform semantic traversals and logical inferences at native Lisp speeds. 
-   - *Homoiconicity:* Since the program (Lisp) and the data (Lisp objects) share the same structure, the agent can manipulate its own memory as easily as it manipulates its own code.
-3. *The Telemetry Store (External):* A high-volume database for sub-deterministic sensory data (system metrics, sensor logs) that the agent monitors and distills into Org-mode "insights."
+In openCortex, a Skill is simply a *single .org file* containing everything:
+- The documentation (prose explaining the skill's purpose)
+- The AI instructions (how the LLM should use this skill)
+- The deterministic code (Lisp that verifies/proposes actions)
 
-** The Psychology: The 2x2 Cognitive Matrix
-|                      | Probabilistic (Neural/Intuitive)                                           | Deterministic (Deterministic/Logical)                                              |
-| Foreground (Active)  | *The Interface:* Fast AI models for conversation and multimodal ingestion. | *The Steward:* Lisp engine that safely retrieves data and enforces security rules. |
-| Background (Passive) | *The Editor:* Deep AI models finding patterns while you sleep.             | *The Librarian:* Lisp engine maintaining data integrity and filing notes.          |
+When the system boots, it compiles these skills directly into the live Lisp image. Skills are hot-reloadable without restarting the daemon.
 
-** The Physiology: Five Core Processes
-1. *Perception:* Automatically vectorizes your input and sets the "Foreground Focus."
-2. *Reasoning:* Uses Lisp-native logic to reconcile contradictions.
-3. *Distillation:* Background loop extracting concepts into permanent, evergreen notes (The Scribe).
-4. *Reflection:* Heartbeat-driven process maintaining structural health (The Gardener).
-5. *Sensation:* Monitors telemetry data and flags significant anomalies.

+* The Three Data Stores
+
+openCortex maintains three distinct representations of your knowledge:
+
+| Store | Format | Location | Purpose |
+|-------|--------|----------|---------|
+| *Source of Truth* | Plaintext .org files | `~/memex/` | Human-readable, version-controlled |
+| *Active Brain* | RAM (Lisp hash tables) | Memory | Fast, live, queryable |
+| *Snapshots* | Binary .snap files | `~/.opencortex/` | Crash recovery, rollback |
+
+The Active Brain is built from the Source of Truth on boot and kept in sync via:
+- Buffer updates from Emacs (when you edit)

 * The Evolutionary Roadmap
 
-** v0.1.0: The Autonomous Foundation (Current Release)
-The initial MVP establishing a secure, auditable Lisp kernel. Features a robust metabolic pipeline, mandatory skill enforcement, and background distillation (The Scribe).
+openCortex's roadmap is designed working backwards from SOTA parity (V 1.0.0), guided by a critical analysis of four reference systems: OpenCode, Claude Code (leaked source), GBrain, and OpenClaw/Hermes. Every borrowed concept is reimplemented in pure Lisp. Every rejected pattern is documented.
 
-** v0.2.0: Interactive Refinement & Self-Editing
-Elevating the user interface and granting the kernel the physical capability to edit its own source code.
-- *Autonomous Self-Editing:* Implementation of File I/O cognitive tools (`:read-file`, `:write-file`, `:replace-string`) and whitelisting `emacs` for autonomous `org-babel-tangle` operations.
-- *High-Fidelity TUI:* Transitioning to a rich, native Lisp TUI via `croatoan` with scrollable history and multi-line input.
-- *Skill Hot-Reloading:* A dedicated mechanism to safely swap compiled Lisp code into the live image without severing client connections.
-- *Automated PATH Handling:* Zero-config installation where the `opencortex` binary is automatically injected into the user's environment.
+** Non-Negotiable Identity
+- Pure Common Lisp + Org-mode. No JSON. No YAML. No external databases.
+- Single-address-space memory (Lisp hash tables in RAM — we *are* the memory).
+- "Thin harness, fat skills" — complexity lives at the edges, not the kernel.
+- One agent composed of many skills. No sub-agent topologies.
+- Plists everywhere — homoiconic communication between all components.
 
-** v1.0.0: The Verified Wrapper (Next Major Target)
-Achieving feature parity with SOTA autonomous agents but with Lisp-grade mathematical security. 
-- *The Tools are External:* Standard bash shell, headless browser (via Playwright), and standard file I/O.
-- *The Safety is Internal:* The Bouncer and Formal Verification gates mathematically prove actions are safe before they touch the OS.
+*** OpenCode: Borrowed / Rejected
 
-** v2.0.0: The Cannibalization
-Replacing string-based tool wrappers with native Lisp data structures to eliminate LLM fragility.
-- *Cannibalizing the Browser:* Ingesting the DOM as a native Lisp AST rather than fighting with Playwright scripts.
-- *Cannibalizing the Shell:* Moving from bash execution to native OS API bindings. Emacs becomes a viewport for the live AST, not a master.
+| Feature | Decision | Rationale |
+|---------|----------|-----------|
+| Permission filtering before LLM sees tools | BORROW | Hook into =generate-tool-belt-prompt= to exclude denied tools. We have =:guard= but no pre-filter. |
+| Hook system (session start/end) | BORROW | Already designing event-orchestrator. Expose via =#+HOOK:= properties. |
+| Skills with YAML frontmatter | REJECT | Our Org-mode =:PROPERTIES:= + =#+FILETAGS= already do this. |
 
-** v3.0.0: True Symbolic Determinism
-The great inversion. The Lisp engine takes the wheel, and the LLM is relegated to a mere semantic translation layer for the messy outside world.
-- *Deterministic Planning:* The core reasoning engine uses formal logic and graph traversal to plan and execute workflows.
-- *Self-Correcting Syntax:* The Lisp engine catches and repairs hallucinated syntax errors without consulting the LLM.
+*** Claude Code: Borrowed / Rejected
+
+| Feature | Decision | Rationale |
+|---------|----------|-----------|
+| ULTRAPLAN / structured task decomposition | BORROW (reimplement) | LLM already generates plist actions. Add task-tree skill that decomposes into Org-mode headline DAGs with terminal states. |
+| 43 integrated tools | BORROW (approach) | Start with ~3. Build more as skills. Keep =def-cognitive-tool= pattern. |
+| 4-tier permission chain (ask/allow/deny) | BORROW (concept) | Three-tier per-tool permission: ask/allow/deny stored in org-objects. |
+| Multi-agent hub-and-spoke topology | REJECT | We have one agent. Concurrency via bordeaux-threads (shared memory). Skills ARE the specialization — intra-process, not inter-process. |
+| Mailbox pattern for dangerous ops | REJECT | Jailed skill packages + Policy skill already provide isolation. Bouncer gate satisfies "worker can't self-approve". |
+
+*** GBrain: Borrowed / Rejected
+
+| Feature | Decision | Rationale |
+|---------|----------|-----------|
+| RESOLVER.md intent routing | BORROW (concept) | =find-triggered-skill= already does this. Enhance with multi-skill triggers for complex intents. |
+| Three search modes (keyword, hybrid, direct) | BORROW | Keep keyword + direct. Hybrid/vector via local Ollama embeddings — no external DBs. |
+| Memory segmentation (brain/agent/session) | BORROW (concept) | Extend org-object with =:scope= property: =:memex= (permanent), =:session= (ephemeral), =:project= (scoped). |
+| 20+ cron jobs for background work | BORROW (concept) | Heartbeat already does this. Enhance with Event Orchestrator's cron registry — pure Lisp. |
+| Sub-agent model routing for cost | BORROW (concept) | Our =*model-selector-fn*= already selects models. Extend to route by complexity tier. |
+| Postgres + pgvector | REJECT | Single-address-space hash tables. No external databases. |
+
+*** opencortex-contrib: Integrate / Reject
+
+| Skill | Decision | Rationale |
+|-------|----------|-----------|
+| self-fix + lisp-repair | INTEGRATE | Merge into =org-skill-self-edit=. Our memory has snapshot/rollback. Add =repair-file= as cognitive tool. |
+| event-orchestrator | INTEGRATE | Merge hooks + cron + routing into ONE skill. Our loop has no unified orchestration. |
+| formal-verification | INTEGRATE | =def-invariant= macro + =verify-action-formally= belong in =org-skill-policy.org= as additional checks. |
+| engineering-standards | INTEGRATE | Git-clean-p gate + "Commit Before Modify" belong in Policy. |
+| sub-agent-manager | REJECT | Redundant with BT threads. Our =defskill= pattern (trigger + probabilistic + deterministic) is intra-process specialization — same goal, zero process overhead. |
+| embedding-generator | BORROW | Ollama embeddings for semantic search — no external vector DB. |

+
+** Design Principles
+
+** 1. Radical Transparency
+
+If you can't explain it, you can't do it. Every action must be auditable. Hidden reasoning is forbidden.
+
+** 2. Autonomy First
+
+Dependency on proprietary systems is debt. Prefer local, offline-capable solutions.
+
+** 3. Zero Bloat
+
+Complexity must be earned, not anticipated. The harness must remain minimal.
+
+** 4. Modularity
+
+The kernel must survive even if all skills fail. Complexity belongs at the edges.
+
+** 5. Mentorship
+
+Teaching is the highest form of assistance. Every action should increase capability.
+
+** 6. Sustainability
+
+Build for the 100-year horizon. Design for offline operation, local inference.

 * Introduction
 Welcome to OpenCortex v0.1.0 (The Autonomous Foundation). OpenCortex is a neurosymbolic AI agent and a Lisp Machine operating system designed to autonomously maintain your Memex (knowledge base) and interact with you via multiple, equal-citizen interfaces.
 
-* Quick Start Installation
-OpenCortex can be installed and booted with a single command:
+* Installation
+OpenCortex is bootstrapped via a single shell script.
 
 #+begin_src bash
-curl -sSL https://raw.githubusercontent.com/gharbeia/opencortex/main/opencortex.sh | bash -s -- setup
+git clone ssh://git@10.10.10.201:2222/amr/opencortex.git
+cd opencortex
+./opencortex.sh setup
 #+end_src
 
-This command will:
-1. Bootstrap the OpenCortex repository into \`~/.opencortex\`.
-2. Install system dependencies (SBCL, Quicklisp, etc.).
-3. Interactively guide you through the initial configuration.
-4. Tangle the literate source code.
-5. Awaken the background daemon.
+This process will install SBCL, Quicklisp, and prompt you to create a `.env` file for your API keys.
 
 * Configuration
-The system is configured via a \`.env\` file in the project root. Key variables include:
+The system is configured via a `.env` file in the project root. Essential variables include:
 
-- \`LLM_API_KEY\`: Your provider key (e.g., \`OPENROUTER_API_KEY\`, \`OPENAI_API_KEY\`).
-- \`PROVIDER_CASCADE\`: The fallback order for LLM providers (e.g., \`openrouter,ollama,anthropic\`).
-- \`MEMEX_DIR\`: The absolute path to your knowledge base (defaults to \`~/memex\`).
+- `OPENROUTER_API_KEY`: Your LLM provider key.
+- `PROVIDER_CASCADE`: The fallback order for LLM providers (e.g., `openrouter,ollama,anthropic`).
+- `MEMEX_DIR`: The absolute path to your knowledge base (defaults to `~/memex`).
 
 * Interacting with OpenCortex
-Once the daemon is running, you can connect via any supported client.
+Because of the Unified Envelope Architecture, the kernel treats all clients as interchangeable. You must first boot the background daemon:
+
+#+begin_src bash
+./opencortex.sh --boot &
+#+end_src
 
 ** Terminal User Interface (TUI)
-For a rich terminal experience with history and background worker status:
+For a rich, split-pane terminal experience:
 #+begin_src bash
-opencortex tui
+./opencortex.sh tui
 #+end_src
 
 ** Command Line Interface (CLI)
 For raw, pipe-friendly interaction:
 #+begin_src bash
-opencortex cli
+./opencortex.sh cli
 #+end_src
 
+** Emacs Integration
+OpenCortex functions as your "foveal vision" inside Emacs.
+1. Ensure `org-agent.el` is loaded.
+2. Run `M-x opencortex-connect`.
+3. Interact via the `*opencortex-chat*` buffer.
+
 * The Memex Structure
-OpenCortex manages a local folder structure representing your "Memex".
-- *Nodes:* Every Org-mode headline is a "node" in the agent's memory graph.
-- *Source of Truth:* Plaintext files are the definitive state.
-- *Autonomous Workers:*
-  - The \`Scribe\` distills chronological logs into structured Zettelkasten notes.
-  - The \`Gardener\` repairs links and flags orphaned nodes.
+OpenCortex assumes a local folder structure representing your "Memex".

 * Stage 3: Act (act.lisp)
 
-** Architectural Intent: Actuation
-The Act stage performs the final physical side-effects of the metabolic pipeline. It takes an approved **Action** (the result of the Reasoning stage) and routes it to the correct physical **Actuator**.
+** Architectural Intent: The Last Mile
 
-Actuators are the "hands" of the OpenCortex. They can be local (printing to a terminal), virtual (executing a shell command), or remote (sending a Matrix message). Crucially, the core microharness does not know *how* to talk to these services; it only knows how to *dispatch* to the registered actuator functions.
+The Act stage is where cognition meets reality. After the Probabilistic engine proposes and the Deterministic engine verifies, Act executes the approved action.
+
+The key insight of the Act stage is that *execution is the point of no return*. Once a command is sent to the shell or a file is written, side effects have occurred. Therefore, Act implements a "last-mile" safety check - even after skills have verified the action, there's a final validation before dispatch.
+
+** Why Separate Actuators?
+
+The actuator pattern decouples /what to do/ from /how to do it/:
+
+- The reasoning engine generates action plists like `(:TYPE :REQUEST :TARGET :SHELL :PAYLOAD ...)`
+- The actuator interprets the target and executes appropriately
+- Adding a new actuator (Telegram, Matrix, etc.) doesn't require changing the reasoning code
+
+This follows the Open/Closed principle: open for extension, closed for modification.
+
+** The Feedback Loop
+
+Act is unique in the pipeline because it can generate new signals. When a tool executes and returns data, that data becomes a new signal that feeds back into Perceive → Reason → Act.
+
+Example feedback chain:
+1. User asks "What files changed today?"
+2. Reason generates shell command action
+3. Act executes shell, gets file list
+4. Act returns file list as feedback signal
+5. Reason processes file list, generates human-readable response
+6. Act displays response

 * Communication Protocol (communication.lisp)
+** Architectural Intent: Secure Inter-Process Communication & Deterministic Framing
 
-** Architectural Intent: Secure Inter-Process Communication
-The Communication Protocol is the bridge between the OpenCortex microharness and the outside world. To maintain the "Zero-Bloat" mandate, the protocol must be:
-1. **Lightweight:** Minimal overhead for low-latency terminal interaction.
-2. **Deterministic:** Strict S-expression framing to prevent injection attacks.
-3. **Transport-Agnostic:** Capable of running over TCP, Unix Sockets, or Standard I/O.
+The ~communication.lisp~ module defines the low-level transport and framing logic for OpenCortex stimuli. 
 
-By utilizing a length-prefixed S-expression format (the "Unified Envelope"), we ensure that both human-readable text and complex Lisp data structures can be transmitted securely without the fragility of JSON or the overhead of Protobuf.

 * Peripheral Vision (context.lisp)
+** Architectural Intent: Context Optimization & The Foveal-Peripheral Hybrid
 
-** Architectural Intent: Contextual Awareness
-The Context stage (often referred to as "Peripheral Vision") is responsible for assembling the situational awareness that the Probabilistic Engine needs to make informed decisions.
+A common failure mode for Large Language Models (LLMs) is the "Lost in the Middle" phenomenon, where the model's reasoning accuracy degrades as its context window becomes saturated with irrelevant data. Naive approaches to context management—such as simple character-count truncation or sliding windows—often sever the structural relationships that define an Org-mode Memex.
 
-In most agent frameworks, context is provided as a massive, unstructured text dump of recent chat history. OpenCortex takes a more sophisticated approach:
-1. **Foveal Focus:** The data immediately relevant to the current task (e.g., the specific Org headline being edited).
-2. **Peripheral Awareness:** Low-resolution metadata about the rest of the Memex (e.g., list of active projects, recent system logs, current time/location).
-3. **Semantic Retrieval:** Utilizing vector embeddings to pull in semantically related nodes from the long-term memory.
+The ~opencortex~ harness implements a deterministic, tree-aware solution: the **Foveal-Peripheral Hybrid Model**.
 
-By balancing these three layers, we provide the agent with a "Wide Angle" view of the user's life without overflowing the LLM's context window.
+*** 1. The Foveal Focus (High Resolution)
+When the harness prepares a prompt for the Probabilistic Engine, it identifies a "Foveal Focus"—typically the specific Org headline or task the user is currently interacting with. This node, along with its immediate children and semantically relevant neighbors, is rendered at "High Resolution," meaning its full body text, properties, and metadata are included in the prompt.
+
+*** 2. The Peripheral Vision (Low Resolution)
+To maintain global awareness without bloating the context window, the rest of the Memex is rendered at "Low Resolution." The harness recursively walks the Memory and generates a skeletal outline consisting only of titles and IDs. This gives the LLM a "mental map" of the entire system, allowing it to reference other projects or skills without needing to see their full content until they are explicitly brought into focus.
+
+*** 3. Deterministic Tree-Walking
+By leveraging Common Lisp's strengths in recursive tree manipulation, the harness can surgically prune the AST before it ever reaches the LLM. This ensures that the structural hierarchy of the Memex is preserved perfectly, even when the content is compressed.

 * The Metabolic Loop (loop.lisp)
+** Architectural Intent
 
-** Architectural Intent: The Heartbeat
-The Metabolic Loop is the high-level coordinator of the OpenCortex. It orchestrates the flow of energy (information) through the system by recursively calling the metabolic stages: Perceive, Reason, and Act.
+The Metabolic Loop is the /cranial nerve reflex/ of OpenCortex. While skills provide specialized intelligence, the loop provides the fundamental rhythm of existence: the continuous processing of signals from perception through cognition to action.
 
-Inspired by biological metabolism, the loop ensures that every stimulus is processed until it reaches "stasis" (no further actions required) or an error occurs. This recursive design allows the agent to chain multiple thoughts and tool calls together into a single cohesive cognitive session.
+Unlike a simple event loop, the Metabolic Loop implements a sophisticated error recovery model. When the system encounters an error, it distinguishes between:
+
+1. *Transient errors* (tool failures, network timeouts) - recoverable, no state rollback
+2. *Critical errors* (undefined functions, malformed data structures) - require memory rollback
+3. *Recursive loops* (signals generating more signals indefinitely) - depth limit enforcement
+
+This design ensures the agent remains stable under adverse conditions while preserving the ability to recover from genuine system failures.
+
+** Why Separate Perceive-Reason-Act?
+
+The three-stage pipeline mirrors the classical sense-think-act paradigm but with a crucial difference: each stage is a pure function that transforms a signal. This allows:
+
+- *Perceive* to normalize raw input into a standardized signal format
+- *Reason* to transform the perceived signal into an approved action (or reject it)
+- *Act* to execute the approved action and potentially generate a feedback signal
+
+The feedback loop (Act returning a signal that feeds back into Perceive) enables complex multi-step operations where each action can trigger subsequent reasoning.
+
+** Thread Safety
+
+The loop operates in a multi-threaded environment:
+- The main thread runs the heartbeat and idle loop
+- Async sensors spawn threads for non-blocking I/O
+- Interrupt handling requires mutex protection to prevent race conditions

 * The Metabolic Pipeline
 
-** Signal Processor (process-signal)
-The primary cognitive processor. It takes a normalized signal and pushes it through the gates. If a gate generates "Feedback" (e.g., a tool result), the function recursively processes that feedback as a new stimulus.
+** process-signal: The Core Engine
+
+This function implements the Perceive-Reason-Act pipeline. It processes a signal through all three stages and handles the feedback loop where Actions can generate new signals.
+
+The depth counter prevents infinite recursion—a signal that generates another signal that generates another, etc. By limiting to depth 10, we ensure the system eventually converges or gracefully terminates.

-* Autonomous Reflection
+** The Feedback Loop Explained
 
-** Heartbeat Mechanism (start-heartbeat)
-The heartbeat ensures the agent remains "alive" even in the absence of external stimuli. It allows background workers like the Scribe and Gardener to trigger periodically.
+The pipeline implements a feedback loop where Act can return a new signal:
+
+1. User input arrives → Perceive normalizes it
+2. Reason generates an action → Act executes it
+3. If the action was a tool call that returned new information → Act returns a feedback signal
+4. Feedback signal feeds back into step 1 for further reasoning
+
+This enables multi-step workflows where each action can trigger additional analysis.
+
+* Heartbeat Mechanism
+
+The heartbeat thread ensures the agent remains alive even without external input. It drives two critical functions:
+
+1. **Latent reflection** - the agent can think without external prompting
+2. **Periodic maintenance** - memory auto-save, orphan detection, etc.

 * Manifest (opencortex.asd)
 
-** Architectural Intent: The ASDF Skeleton
-The ~opencortex.asd~ file is the physical blueprint of the Lisp Machine. It uses **Another System Definition Facility (ASDF)** to orchestrate the compilation, dependency resolution, and loading of all harness modules.
+** Architectural Intent: The Thin Harness Philosophy
 
-In standard Common Lisp projects, dependency graphs can be complex and non-linear. However, the OpenCortex harness mandates a strict, linear bootstrap sequence.
+The ~opencortex.asd~ file is the physical blueprint of the Lisp Machine. It uses **ASDF** (Another System Definition Facility) to orchestrate compilation and loading of all harness modules.
 
-*** Strict Serial Loading (:serial t)
-The harness uses the ~:serial t~ flag. This is a critical design choice that ensures every file is compiled and loaded in the exact order it appears in the ~:components~ list. 
-- *Why?* This eliminates "macro-not-found" errors by guaranteeing that the ~package.lisp~ (where the core namespace is defined) and ~skills.lisp~ (where core macros are defined) are always established before any behavioral logic or dynamic skills are loaded.
+The core design principle is *Thin Harness, Fat Skills*:
 
-*** Separation of Concerns
-The manifest defines three distinct systems to minimize runtime bloat and maximize portability.
+- **Harness** = The minimal, unbreakable core (protocol, signal processing, memory)
+- **Skills** = The intelligence layer (policy, validation, actuation, LLM integration)
+
+This separation means:
+- The harness rarely changes (immune system)
+- Skills can be hot-loaded, modified, and swapped without touching the core
+- Bugs in skills don't crash the system
+
+** Why ASDF?**
+
+ASDF is the de facto standard for Common Lisp project management. It:
+1. Handles dependency resolution and loading order
+2. Compiles files in the right order (preventing "undefined function" errors)
+3. Supports system building for deployment
+4. Integrates with Quicklisp for dependency management

-** Core Harness System
-This system defines the "Thin Harness"—the minimalist microkernel responsible for the protocol and the metabolic loop.
+* Design Decisions
+
+** Strict Serial Loading
+
+The harness uses ~:serial t~ in the ASDF definition. This means:
+
+1. Files are loaded in order: package → skills → communication → memory → context → perceive → reason → act → loop
+2. ~package.lisp~ is always loaded before any code that uses its symbols
+3. ~skills.lisp~ (defining macros like ~defskill~, ~def-cognitive-tool~) loads before skills
+
+This eliminates "macro not found" errors that plague non-linear loading systems.
+
+** Why Not Module Dependencies?**
+
+Traditional ASDF uses ~:depends-on~ to declare dependencies. We use ~:serial t~ because:
+
+1. *Explicit is better than implicit* - the loading order is visible in one place
+2. *Prevents circular dependencies* - skills are loaded after the harness, never before
+3. *Simpler debugging* - when something fails, the loading order is always clear
+
+** Isolation of Tests
+
+The testing system (~:opencortex/tests~) is separate from the production system (~:opencortex~). This means:
+
+- Production deployments don't load FiveAM (saves memory, reduces attack surface)
+- Tests can be run independently: ~(ql:quickload :opencortex/tests)~
+- Test data doesn't pollute the production image

+* The Harness Boundary Contract
+
+** Why a Boundary Contract?
+
+The harness is the immune system of OpenCortex. If it grows fat (accumulating features, dependencies, complexity), it becomes harder to:
+- Verify for security
+- Debug when things go wrong
+- Maintain across versions
+
+The Boundary Contract defines what IS the harness vs. what belongs in skills.
+
+** Primary Boundary Files
+
+| File | Purpose | Modification |
+|------|---------|--------------|
+| ~harness/*.org~ | Literate source of truth | Only via Org edits + tangle |
+| ~opencortex.asd~ | System manifest | Only via Org edits + tangle |
+| ~library/*.lisp~ | Tangled from .org | NEVER edit directly |
+
+** Generated Artifacts (NOT Primary)
+
+The ~library/*.lisp~ files are tangles from the ~harness/*.org~ files. They are derivative artifacts. Direct modification violates the Literate Granularity standard.
+
+** Protected Paths
+
+The Policy skill guards these paths by default:
+
+#+begin_src lisp
+(defvar *modularity-protected-paths*
+  '("harness/"
+    "opencortex.asd"
+    "library/package.lisp"
+    "library/communication.lisp"

+    "library/perceive.lisp"
+    "library/reason.lisp"
+    "library/act.lisp"
+    "library/loop.lisp"))
+#+end_src
+
+Any agent action proposing to modify these files must include a ~:modularity-justification~ field explaining why the change cannot be implemented as a skill.
+
+** Enforcement Chain
+
+1. *Policy Skill* (priority 500) - Checks for missing justifications
+2. *Bouncer Skill* (priority 100) - Intercepts unauthorized modifications
+3. *Git Hooks* (optional) - Prevents direct .lisp commits

 #+STARTUP: content
 
-* Homoiconic Memory (memory.lisp)
+* The System Memory (memory.lisp)
+** Architectural Intent: The Single Address Space (Live Memory)
 
-** Architectural Intent: The Live Graph
-The Memory module is the "conscious mind" of the OpenCortex. Unlike traditional agents that rely on slow, external databases (SQL or Vector), OpenCortex maintains your entire Memex as a live, homoiconic graph of Lisp objects in RAM.
+Yes, the Memory module is the cognitive bedrock of the opencortex. It is not a database; it is the agent's live, active "brain" state.
 
-*** Why RAM-First?
-1. **Zero-Latency Inference:** Traversing complex associations between notes and tasks occurs at native Lisp speeds, without the overhead of context-switching to a database driver.
-2. **Unified Data Model:** Since the program (Lisp) and the data (the Memory) share the same structure, the agent can manipulate its own memory as naturally as it manipulates its own code.
-3. **Graph Sovereignty:** By keeping the graph in-process, we ensure that the user's private knowledge base never leaves the host machine unless explicitly requested by a gateway.
+Traditional architectures rely on external databases (SQLite, Vector DBs) which introduce I/O latency and structural impedance. The opencortex architecture chooses a different path: the **Single Address Space**. By treating the entire knowledge base as a graph of Lisp pointers, we achieve microsecond recollection and total structural transparency.
 
-** Pipeline Initialization
+- **Pointer-Based Reasoning:** By loading the entire knowledge graph into a live Common Lisp hash table, we achieve microsecond recollection. The harness doesn't "search a file"; it traverses a memory pointer.
+- **Memory Imaging:** The ability to snapshot the Lisp image allows the agent to resume its entire cognitive state instantly, solving the "Cold Start" problem.
+- **Merkle-Tree Integrity:** Every node in the Memory is cryptographically hashed. By recursively hashing content and children, the root hash provides a single, immutable fingerprint of the entire system state.

-* Integrity and Hashing
-
-** Merkle Hashing (compute-merkle-hash)
-To ensure data integrity and detect changes during external edits, we utilize Merkle-tree hashing. A node's hash is derived from its own content plus the hashes of its children.
+** Merkle Tree Integrity (compute-merkle-hash)
+The `compute-merkle-hash` function ensures the cryptographic integrity of the knowledge graph. A node's hash depends on its own properties and the hashes of all its children. This creates a recursive fingerprint where any change to a single note propagates up to the root hash.

 * Stage 1: Perceive (perceive.lisp)
 
-** Architectural Intent: Sensory Ingestion
-The Perceive stage is the "sensory cortex" of the OpenCortex. Its primary responsibility is to take raw, unstructured stimuli from the outside world—whether from a TCP socket, a system interrupt, or a background heartbeat—and normalize them into high-fidelity internal **Signals**.
+** Architectural Intent: Sensory Normalization
 
-Normalization is critical because it shields the subsequent reasoning and actuation stages from the messiness of different transport protocols. Whether a message arrives via a TUI, a Signal bot, or an internal timer, the core "Brain" perceives a consistent Lisp property list.
+The Perceive stage is the "sensory cortex" of OpenCortex. Its job is to take raw stimuli from the outside world and transform them into standardized Signals that the rest of the pipeline can process.
 
-** Pipeline Initialization
-Ensuring we are in the correct namespace for sensory processing.
+Raw stimuli come from diverse sources:
+- Terminal input (CLI)
+- Emacs org-mode buffers (via swank)
+- Telegram/Signal messages
+- Heartbeats (internal clock)
+- Shell command outputs
+
+Each source has its own format and protocol. Perceive normalizes all of them into the Signal format:
+
+: (TYPE :EVENT META (...) PAYLOAD (...))
+
+** Why Normalize?
+
+Without normalization, each downstream component (Reason, Act) would need to understand each input format. With normalization:
+
+1. The gateway layer (CLI, Emacs, Telegram) just sends raw messages
+2. Perceive transforms them into Signals
+3. Reason and Act work with a single, consistent format
+4. Adding new input sources only requires gateway code, not changes to the core
+
+** The Signal Format
+
+Signals are property lists with a consistent structure:
+
+| Key | Description |
+|-----|-------------|
+| :type | :EVENT, :REQUEST, :RESPONSE, :LOG |
+| :payload | The actual content (sensor data, actions, etc.) |
+| :meta | Metadata: source, session, reply stream |
+| :status | Processing status: :perceived, :reasoned, :acted |
+| :depth | Recursion depth for feedback loops |
+| :approved-action | Set by Reason, executed by Act |
+| :foveal-focus | ID of the node user is interacting with |
+
+** Async vs Sync Processing
+
+Some sensors (user input, chat messages) are processed asynchronously in dedicated threads. This prevents:
+- A slow API call from blocking the entire system
+- Race conditions when multiple inputs arrive simultaneously
+
+Other sensors (heartbeats, interrupts) are processed synchronously to maintain ordering guarantees.
+

 #+end_src
 
-** Sensory Concurrency (Async Sensors)
-To maintain the agent's responsiveness, we distinguish between "Fast" and "Slow" sensors. Sensors that require extensive processing or external API calls are routed to asynchronous threads to prevent blocking the main metabolic pipeline.

+  synchronously to maintain temporal ordering.")

 * Stage 2: Reason (reason.lisp)
 
-** Architectural Intent: Unified Cognition
-The Reason stage is the cognitive engine of the OpenCortex. Its primary responsibility is to bridge the gap between raw sensory data (Perceive) and physical side-effects (Act). 
+** Architectural Intent: The Dual-Engine Cognitive Architecture
 
-Cognition is split into two distinct modes:
-1. **Probabilistic Reasoning:** Utilizing LLMs to generate creative proposals and understand natural language intent.
-2. **Deterministic Verification:** Utilizing native Lisp logic to verify and constrain the neural proposals against security and physics invariants.
+The Reason stage implements the core innovation of OpenCortex: the separation of probabilistic reasoning (neural/LLM) from deterministic verification (logic/safety).
 
-This hybrid approach ensures the agent is both intelligent and mathematically safe.
+This dual-engine design solves a fundamental problem in AI safety:
+
+1. *Probabilistic Engine* - Uses LLMs for semantic understanding, natural language generation, and complex reasoning. It is powerful but can hallucinate, make syntax errors, or propose unsafe actions.
+
+2. *Deterministic Engine* - Uses formal verification (skills) to check LLM proposals before execution. It is slower but provably correct.
+
+The LLM proposes; the skills verify. This is the "Bouncer Pattern" - the deterministic engine is literally a bouncer that checks the LLM's proposals at the door before letting them through to execution.
+
+** Why Plists for Communication?
+
+The Reason stage communicates exclusively through property lists (plists). This design choice reflects the homoiconic nature of Lisp - plists are native data structures that can be read, written, and manipulated by the same code that processes them.
+
+A plist message like:
+: (TYPE :REQUEST TARGET :CLI PAYLOAD (ACTION :MESSAGE TEXT "Hello"))
+
+Is simultaneously:
+- Human-readable text
+- Machine-parseable data structure
+- Executable Lisp code
+
+This means the reasoning pipeline can generate, modify, and execute its own communication protocol without external parsing.

 * The Skill Engine (skills.lisp)
+** Architectural Intent: Late-Binding Intelligence
 
-** Architectural Intent: Hot-Reloadable Intelligence
-The Skill Engine is the modular heart of the OpenCortex. By separating cognitive and physical capabilities into discrete "Skills," we allow the system to evolve without modifying the core Lisp microharness.
+A static, hardcoded architecture is inherently fragile. The ~opencortex~ Skill Engine enables **Late-Binding Intelligence**, allowing the system to discover and integrate new cognitive capabilities (actuators, solvers, sensors) at runtime without a kernel restart.
 
-*** Core Principles
-1. **Isolation:** Every skill resides in its own Lisp package, preventing global namespace pollution and variable collisions.
-2. **Topological Bootstrapping:** Skills can declare dependencies on other skills. The harness automatically calculates the correct loading order.
-3. **Hot-Reloading:** Since Skills are defined as Literate Org files, the agent can edit, re-tangle, and re-load its own skills at runtime without a system restart.
-4. **The Bouncer Pattern:** Every skill must define a deterministic gate. This is the primary security layer where native Lisp logic verifies probabilistic AI proposals.

 #+STARTUP: content
+#+FILETAGS: :tui:ux:client:
 
-* OpenCortex TUI Client (tui-client.lisp)
+* Overview
+The OpenCortex TUI Client is a standalone Common Lisp application built on **Croatoan**. It provides a real-time, multi-window interface for interacting with the OpenCortex daemon.
 
-** Architectural Intent: High-Fidelity Interaction
-The TUI Client is a standalone consumer of the OpenCortex protocol. It uses the ~croatoan~ (ncurses) library to provide a split-pane, interactive terminal experience.
-
-*** Design Requirements
-1. **Concurrency:** The client must listen for incoming protocol events (heartbeats, status updates, thoughts) in a background thread to prevent the UI from freezing.
-2. **Buffer Safety:** User input must be captured in a thread-safe buffer and framed correctly before being sent to the daemon.
-3. **Transparency:** The status bar must provide real-time feedback on the state of background workers (Scribe and Gardener).
-
-** Package Context
+* Implementation

 #+FILETAGS: :system:bouncer:authorization:autonomy:
 
 * Overview
-The *Deterministic Engine Bouncer* is the authorization gate for high-risk actions. It serializes intercepted actions into Org nodes ("Flight Plans") and re-injects them once manually approved by the Autonomous.
+
+The *Bouncer Skill* is the physical security layer of OpenCortex. While the Policy skill enforces constitutional invariants (transparency, autonomy, modularity), the Bouncer enforces operational security checks.
+
+Think of Policy as the constitution and Bouncer as the bouncer at the door:
+- **Policy** asks: "Is this action aligned with our values?"
+- **Bouncer** asks: "Is this action safe to execute?"
+
+** The Flight Plan Pattern
+
+High-risk actions don't simply pass or fail—they can enter the "Flight Plan" approval workflow:
+
+1. Bouncer intercepts a risky action
+2. Creates an Org node ("Flight Plan") describing the action
+3. User manually approves the flight plan in Emacs
+4. Bouncer detects approval on next heartbeat
+5. Action is re-injected with `approved = t` flag, bypassing the gate
+
+This creates human-in-the-loop oversight for dangerous operations without blocking the system entirely.
+
+** Why a Separate Skill?**
+
+Security and policy are separated for clarity and auditability:
+- Policy decisions can be explained (they reference invariants)
+- Bouncer decisions are technical (they reference threat vectors)
+
+When something is blocked, the logs clearly show which layer blocked it and why.

-* Deep Packet Inspection (DPI)
-The Bouncer ensures the action is "safe" by inspecting the payload content via Deep Packet Inspection.
+* Security Vectors
 
-** Secret Exposure Check
-Retrieves all active secrets from the vault and scans the payload for potential leaks.
+The Bouncer implements the 5-Vector security model:
 
-#+begin_src lisp
+| Vector | Threat | Response |
+|--------|--------|----------|
+| Secret Exposure | API keys, passwords in output | Hard block |
+| Network Exfiltration | Data sent to unauthorized hosts | Approval required |
+| Shell Execution | Arbitrary command execution | Approval required |
+| File Modification | Writing/deleting files | Soft check |
+| Eval Execution | Arbitrary code evaluation | Approval required |
+
+** Secret Exposure Detection
+
+The vault stores sensitive credentials. This check scans action text for vault secrets to prevent accidental exposure.

+
+  This prevents the catastrophic failure mode where the agent
+  accidentally echoes an API key in its response or log output.

 * Overview
 The *Credentials Vault* is the high-security enclave for the OpenCortex. It centralizes the management of LLM API keys, OAuth sessions, and browser cookies. By consolidating these into a single vault, we ensure that sensitive tokens are handled with uniform masking, validation, and Merkle-integrated persistence.
 
-** Architectural Intent: The Secure Enclave
+* Phase A: Demand (PRD)
+:PROPERTIES:
+:STATUS: SIGNED
+:END:
+
+** 1. Purpose
+Securely manage all authentication tokens required for the opencortex to operate.
+
+** 2. User Needs
+- *Unified Storage:* Single interface for API keys and Session Cookies.
+- *Masked Logging:* Ensure credentials never appear in plaintext in `harness-log`.
+- *Guided Onboarding:* Retain and improve the Google/Gemini cookie handshake.
+- *Persistence:* Securely save credentials to the Memory via Merkle-Tree snapshots.
+
+* Phase B: Blueprint (PROTOCOL)
+:PROPERTIES:
+:STATUS: SIGNED
+:END:
+
+** 1. Architectural Intent
 The vault provides a secure lookup table in RAM, backed by the persistent Memory. Access is restricted to internal kernel requests and explicitly authorized deterministic gates.
 
-The primary goal of the vault is to prevent "Credential Bleed"—the accidental leaking of API keys into logs, terminal history, or neural contexts. It achieves this by providing a unified getter that automatically masks its output for diagnostic use.

 * Overview
 The *Autonomous Gardener* is the metabolic immune system of the Memex. It autonomously audits the knowledge graph for structural decay—broken links, orphaned nodes, and missing metadata—ensuring that the system remains coherent and navigatable over long horizons.
 
-** Architectural Intent: Graph Integrity
-In a self-evolving Memex, structural decay is inevitable. Links break as notes are renamed, and nodes become orphaned as projects are abandoned. The Gardener ensures that the "Vibe" of the Memex remains healthy by:
-1. **Auditing:** Identifying broken `id:` links.
-2. **Analysis:** Flagging nodes with zero inbound or outbound connections (Orphans).
-3. **Reporting:** Logging structural issues for user review or future autonomous repair.

+
+* Overview
+The *Lisp Validator* is the primary structural gate for the Probabilistic-Deterministic Lisp Machine. It eliminates the token-waste of probabilistic paren-balancing by providing a deterministic, three-phase validation pipeline: Structural, Syntactic, and Semantic. It is exposed as a cognitive tool so both the harness and the Probabilistic Engine can invoke it before declaring code complete.

+:END:
+
+** 1. Purpose
+Provide a deterministic, fast, and auditable validation gate for all Lisp code proposals.

+** 2. User Needs
+- *Structural Validation:* Detect unbalanced parentheses, brackets, and unterminated strings without invoking the reader.
+- *Syntactic Validation:* Ensure the code can be read by SBCL with `*read-eval*` disabled.
+- *Semantic Validation:* Optionally enforce a whitelist of safe symbols for sandboxed execution.
+- *Tool Exposure:* The Probabilistic Engine must be able to call this as a cognitive tool.
+
+** 3. Success Criteria
+- [X] Structural check runs in O(n) and catches all paren/string defects.
+- [X] Syntactic check catches reader errors and malformed sexps.
+- [X] Semantic check blocks non-whitelisted symbols when strict mode is enabled.

 * Overview
 The *Unified LLM Gateway* is the single sensory and reasoning interface for all neural backends. It consolidates the previously fragmented provider skills into a high-integrity dispatch layer, standardizing credential management, error handling, and payload formatting.
 
-** Architectural Intent: The Neural Dispatch
-The gateway utilizes a functional dispatch pattern. A single entry point, ~execute-llm-request~, resolves the provider-specific nuances (URLs, headers, JSON structures) while exposing a uniform interface to the harness.
+* Phase B: Blueprint (PROTOCOL)
 
-By abstracting the provider details, we allow the agent to swap "brains" mid-thought based on cost, speed, or task complexity without any change to the core reasoning logic.

 #+TITLE: SKILL: System Policy
 #+STARTUP: content
 #+FILETAGS: :platform:policy:alignment:autonomy:
 
 * Overview
-The *opencortex* is a probabilistic-deterministic harness for a personal operating system. It uses Org-mode as its native memory and Common Lisp as its deterministic reasoning engine.
+
+The *Policy Skill* is the constitutional law of OpenCortex. It defines the non-negotiable constraints that every agentic action must satisfy before reaching the actuator layer.
+
+Unlike a passive manifesto, Policy is *enforced* by the Deterministic Engine. The LLM proposes; Policy verifies. If an action violates an invariant, Policy blocks it and returns an auditable explanation.
+
+** Why a Constitutional Approach?**
+
+AIs fail in two ways:
+1. *Underconstraint* - They do harmful things because no one told them not to
+2. *Overconstraint* - They refuse to act because every action triggers a warning
+
+OpenCortex solves this with a *hierarchy of invariants*:
+- Some invariants block absolutely (Transparency, Modularity)
+- Others warn but don't block (Autonomy debt, Sustainability debt)
+
+This allows the agent to be both *safe* and *usable*.
+
+** The Philosophical Foundation
+
+OpenCortex is not just software—it's a *personal operating system* designed for the 100-year horizon. The Memex must outlive:
+- Cloud services that get discontinued
+- Programming languages that fall out of fashion
+- Hardware platforms that become obsolete
+
+Therefore, Policy encodes not just rules, but *values*:
+- Radical Transparency → Auditability is non-negotiable
+- Autonomy → Dependency on proprietary systems is debt, not strength
+- Zero-Bloat → Complexity is cost, not feature
+- Modularity → The kernel must survive even if all skills fail
+- Mentorship → Teaching is the highest form of assistance
+- Sustainability → Offline capability is a feature, not a limitation
 
 * Package Context
-Every skill executes within its own jailed package namespace, while inheriting core harness symbols.

+* The Override Hierarchy
+
+When two invariants conflict, resolution follows a strict priority order. This prevents the agent from freezing on ethical edge cases.
+
+| Priority | Invariant | Philosophy |
+|----------|-----------|------------|
+| 500 | Transparency | If you can't explain it, you can't do it |
+| 400 | Autonomy | Independence from proprietary control is the primary goal |
+| 300 | Zero-Bloat | Complexity must be earned, not imported |
+| 250 | Modularity | Complexity belongs at the edges, not the core |
+| 200 | Mentorship | Teaching increases capability; doing removes it |
+| 100 | Sustainability | Offline capability today enables 100-year survival |

+even if it would be educational.")

 * The Core Invariants
-This document contains the *Core System Policy*. These are non-negotiable philosophical and technical constraints that every agentic action MUST satisfy. The Deterministic Engine uses these headlines as a "Moral Compass" during the decision stage.
 
-** 1. Autonomy Above All
-Every action must increase the user's independence from centralized, proprietary platforms. If a tool or library introduces a dependency on a non-autonomous entity, it must be flagged for replacement.
+** 1. Radical Transparency
+
+*The maxim: "If you can't explain it, you can't do it."*
+
+The agent's Thought Stream must be fully auditable. Hidden reasoning or obfuscated logic violates the system's core purpose: a transparent, comprehensible AI assistant.
+
+At the gate:
+- Every action must be a valid, inspectable data structure
+- Every user-facing action must carry an `:explanation`
+- Log messages must include the triggering invariant

-The agent's goal is not to "do it for the user," but to "empower the user." Every autonomous action must be explained at a level that increases the user's technical understanding of the Lisp Machine.
+** 2. Autonomy Above All

 * Overview
-The *Autonomous Scribe* is the background architect of the Memex. Its primary responsibility is the "Nightly Distillation": a process that scans chronological daily logs, extracts evergreen concepts, and formalizes them into atomic Zettelkasten notes.
+The *Autonomous Scribe* is the background architect of the Memex. It is responsible for the "Nightly Distillation": a process that scans chronological daily logs, extracts evergreen concepts, and formalizes them into atomic Zettelkasten notes.
 
-** Architectural Intent: Continuous Distillation
-The Scribe transforms the "Noise" of daily streams into the "Signal" of permanent knowledge. By operating in the background, it ensures that your knowledge graph grows autonomously, even when you aren't actively organizing it.
+* Phase A: Demand (PRD)
+:PROPERTIES:
+:STATUS: SIGNED
+:END:
 
-It utilizes a "Read-Reason-Write" pattern:
-1. **Read:** Identifies new thoughts in the ~daily/~ folder.
-2. **Reason:** Uses the Probabilistic Engine to extract atomic, evergreen concepts.
-3. **Write:** Commits the distilled notes to the ~notes/~ folder with proper back-links.
+** 1. Purpose
+Automate the conversion of ephemeral, time-stamped thoughts into a permanent, structured knowledge graph.
 
-* Implementation
+** 2. Success Criteria
+- [ ] *Capture:* Identify new headlines in the `daily/` directory that haven't been distilled yet.
+- [ ] *Privacy:* Strictly ignore any node tagged with `@personal`.
+- [ ] *Extraction:* Use neural reasoning to extract atomic concepts from raw logs.
+- [ ] *Formalization:* Create new `.org` files in the `notes/` directory with proper Org-ID and back-links to the source.

+** 1. Architectural Intent
+The Scribe reacts to the `:heartbeat` sensor. It maintains a state file (`scribe-state.lisp`) to track the last processed timestamp. It performs a "Read-Reason-Write" loop:
+1. **Read:** Scan `daily/*.org` for nodes updated after the last checkpoint.
+2. **Reason:** Ask the LLM to "Extract atomic notes from this text".
+3. **Write:** Commit the resulting nodes to the `notes/` directory.
