Per-command dispatch table, hierarchical config menu, fix dialog navigation

- Replace 15-clause command-dispatch cond with per-command functions
  + dispatch table; fixes 19 SBCL compiler errors (loop/dotimes
  inside cond)
- Add hierarchical config menu: Config → Providers/Cascade/Network/
  Folders/Identity with breadcrumb dialog titles
- Add /config command for .env file management (provider keys,
  cascade, proxy, timeout, folders)
- Add /identity and /help <topic> commands
- Fix process-key-event dialog Enter handler double-pop that
  made submenus invisible
- Fix command-dispatch-prefix catch-all clause that shadowed
  subsequent prefix handlers

-* Quick Install
+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.
+
+*Install:*
 
 #+begin_src bash
-curl -fsSL https://raw.githubusercontent.com/amrgharbeia/opencortex/main/opencortex.sh | bash -s configure
+curl -fsSL https://raw.githubusercontent.com/amrgharbeia/passepartout/main/passepartout | bash -s configure
 #+end_src
 
-Then run ~opencortex tui~ to start chatting.
+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.
 
-* Meet OpenCortex
+* What is an AI Agent?
 
-Most AI assistants are just chatbots. You ask a question, they answer, they forget you exist. They trap your conversations in proprietary web apps and silo your data.
+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.
 
-*OpenCortex is different. It is an AI that lives inside your own text files.*
+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.
 
-It runs locally on your machine. It reads your notes, organizes your life, executes tasks, and gardens your knowledge base—all while keeping your data in plain text files you own completely.
+* What Makes Passepartout Different
 
-* Why OpenCortex Exists
+** Every action is verified, not trusted.
 
-The current generation of AI agents have a fundamental flaw: they prioritize quick demos over long-term reliability and user sovereignty.
+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.
 
-The biggest problem is data ownership. Most agents bury your memories in opaque databases. If you want to see your own data, you have to ask the AI to fetch it. If the app shuts down, your data is gone.
+Every gate costs 0 LLM tokens. Every gate is a Common Lisp function, not a prompt. Every gate runs for every action, unconditionally.
 
-OpenCortex solves this with total plain-text transparency. Your entire life is a folder of text files. OpenCortex manages them the same way you do—with any text editor. No database to migrate, no schema to update, no lock-in.
+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.
 
-* What Makes OpenCortex Different
+** The more you use it, the cheaper it gets (architectural aspiration)
 
-Most AI agents are Python applications that happened to call an LLM. OpenCortex is different. It is built in pure Common Lisp—top to bottom, no wrapper, no translation layer.
+Passepartout is designed with a downward cost curve — an architectural property, not yet measured empirically. Here is the thesis.
 
-The kernel is Lisp. The skills are Lisp. The memory system is Lisp. The TUI is Lisp. One language from the hardware to the agent's thoughts.
+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.
 
-Python agents need a second language for configuration (YAML), a third for memory (JSON or SQLite), and a fourth for deployment (Docker). OpenCortex needs SBCL. That's it.
+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.
 
-This is not nostalgia for the 1980s. Lisp has two properties that matter for an autonomous agent.
+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.
 
-First, code is data. In Lisp, the agent can read its own code the same way it reads a text file. It can parse its skills, understand their structure, and modify them at runtime. Python's AST is a foreign object—the agent can inspect it, but not treat it as something it owns.
+** It edits its own source code. Verified before execution.
 
-Second, stability. The Common Lisp specification has been stable for decades. Your code does not break because a library changed its API. Dependencies do not rot. A Lisp program from 1995 still runs today.
+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.
 
-Your data lives in Org-mode files. Not a database. Not JSON. Not a vector store. Just plain text that you can read in any editor, search with grep, and back up any way you want.
+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.
 
-This matters because every other agent makes your data dependent on their app. Their database schema defines what you can store. Their migration scripts decide whether your data survives an upgrade. OpenCortex has no schema. Your memory is a folder of text files. It survives app updates, platform switches, and decades of use.
+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.
 
-The agent fixes itself. When it encounters an error, it can modify its own code, apply surgical fixes, and learn from the outcome to improve and grow. Skills hot-reload at runtime, so you can extend the system without restarting. And if something goes wrong during a complex operation, it snaps back to a known-good state.
+** Your memory and your tasks are the same format. Org-mode.
 
-* Three Problems Every Agent Ignores
+Passepartout makes a bet that most systems consider too expensive: humans and machines should share the same file format. That format is Org-mode.
 
-Every other AI assistant has three fundamental flaws that OpenCortex addresses.
+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.
 
-The first is the data silo. Most agents bury your memories in opaque databases. If you want to see your own data, you have to ask the AI to fetch it. If the app shuts down, your data is gone. OpenCortex stores everything in plain text files that you own. No migration needed, no schema to update, no lock-in.
+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.
 
-The second is the hallucination problem. Most agents pipe AI-generated text directly into your terminal. If the model hallucinates, it can delete your files or break your system. OpenCortex splits its brain into two parts. The creative brain (the LLM) suggests actions. The strict guard (deterministic logic) intercepts every proposal before it touches a file or runs a command. If the AI hallucinates, the guard blocks it.
+** Works offline. Works locally. The safety doesn't stop.
 
-The third is cloud dependency. Most assistants rely entirely on big tech APIs. When your internet drops, or the service goes down, your assistant dies. Worse, your private notes are constantly sent to third-party servers. OpenCortex runs on your own hardware using free, open-source models. Your private data never leaves your laptop. Cloud models are optional—used only when you explicitly allow them for complex tasks.
+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 Onboarding Trifecta
-
-`opencortex setup` guides you through configuring LLM providers. Tell it how to talk to Ollama, Groq, OpenRouter, or your own endpoint.
-
-`opencortex gateway link <platform> <token>` connects external chat gateways. Talk to your agent from Telegram while it works on your files.
-
-`opencortex doctor` shows you what's working, what's broken, and what needs attention.
-
-* Architecture
-
-OpenCortex has three layers.
-
-The Harness is the kernel. It runs the [[file:harness/loop.org][metabolic loop]]—Perceive → Reason → Act—each signal moving through normalization, LLM reasoning, skill verification, and action execution. Depth limits prevent infinite loops. The [[file:harness/memory.org][memory system]] persists to plain-text Org-mode files with snapshot and rollback on errors.
-
-The Skills are userland—thin harness, fat skills. Modular skills load at runtime. Diagnostics, Configuration, LLM Gateway, Shell Actuation, Emacs Editing, Self-Edit, Self-Fix, Credentials Vault, Tool Permissions, Protocol Validator, and more. Each is an independent Org-mode module. Add new skills without touching the kernel.
-
-The Interface is what you use to talk to the agent. A native Lisp [[file:harness/tui-client.org][TUI]] with semantic highlighting and history. A [[file:harness/communication.org][TCP socket server]] for CLI interaction. External channels via the gateway—Telegram and beyond.
+See [[file:docs/USER_MANUAL.org][User Manual]] for the full guide.
 
 * Project Documentation
 
-OpenCortex practices what it preaches—the documentation lives in the code.
-
-The [[file:USER_MANUAL.org][User Manual]] covers setup, configuration, and commands. The [[file:docs/ROADMAP.org][Evolutionary Roadmap]] shows our plan for reaching state-of-the-art capabilities. The [[file:docs/CONTRIBUTING.org][Contributing]] guide teaches you how to add new skills.

-#+TITLE: OpenCortex User Manual
-#+AUTHOR: Agent
-#+STARTUP: content
-#+FILETAGS: :docs:manual:
-
-* Introduction
-Welcome to the OpenCortex User Manual. This guide provides the operational knowledge required to manage your sovereign Lisp Machine and its neural skills.
-
-* System Architecture
-OpenCortex follows a "Purified Kernel" model. The core harness handles essential I/O, while all high-level logic resides in sovereign skills.
-
-** XDG Directory Standard
-To ensure POSIX compliance, OpenCortex stores its files in standard Linux locations:
-
-| Type | Path | Purpose |
-| :--- | :--- | :--- |
-| **Config** | `~/.config/opencortex/` | User settings, `.env` secrets, and provider registry. |
-| **Data** | `~/.local/share/opencortex/` | Tangled Lisp artifacts and the compiled engine. |
-| **State** | `~/.local/state/opencortex/` | Brain snapshots, logs, and Merkle-memory. |
-| **Bin** | `~/.local/bin/opencortex` | The global CLI shim. |
-
-* Command Reference
-
-** `opencortex setup`
-The interactive configuration wizard. Use this to:
-- Define your identity and the Agent's name.
-- Register LLM providers (Ollama, Groq, Anthropic, etc.).
-- The wizard automatically splits sensitive tokens into `~/.config/opencortex/.env`.
-
-** `opencortex gateway link <platform> <token>`
-Connects OpenCortex to external communication gateways.
-- **Example:** `opencortex gateway link telegram <my_bot_token>`
-- **Example:** `opencortex gateway unlink telegram` to disable
-- **Example:** `opencortex gateway list` to see status
-
-** `opencortex doctor`
-Your primary diagnostic tool. Run this if the system feels sluggish or fails to boot. It verifies:
-- External dependencies (sbcl, git, socat).
-- XDG directory existence and permissions.
-- LLM connectivity.
-
-** `opencortex tui`
-Launches the native Lisp Terminal User Interface.
-- **Highlighting:** Semantic color-coding for Lisp and Org syntax.
-- **Scrolling:** Use `PgUp`/`PgDn` to navigate history.
-- **Exit:** Type `/exit` or `Ctrl+C` to close.
-
-* Configuration Strategy
-OpenCortex uses a **Hybrid Storage** model for maximum security and flexibility.
-
-** 1. Secrets (`.env`)
-Found in `~/.config/opencortex/.env`. This file stores raw API tokens. It is never automatically read by the Lisp structural parser to prevent accidental leakage into logs.
-
-** 2. Metadata (`providers.lisp`)
-Found in `~/.config/opencortex/providers.lisp`. This stores non-sensitive configuration like model names, base URLs, and user preferences as native Lisp S-expressions.
-
-* Troubleshooting
-If `opencortex doctor` reports a `FAIL`:
-1. Check that your `PATH` includes `/usr/bin` and `/usr/local/bin`.
-2. Ensure `sbcl` is installed.
-3. If LLM connectivity fails, verify your API key in `~/.config/opencortex/.env`.

+#+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 |
+|-----|-------|---------|
+| ~:TYPE~ | ~:REQUEST~, ~:EVENT~, ~:RESPONSE~, ~:LOG~, ~:STATUS~ | Message category |
+| ~:META~ | plist | ~:SOURCE~, ~:SESSION-ID~, ~:reply-stream~ |
+| ~:PAYLOAD~ | plist | Action-specific data (~:SENSOR~, ~:ACTION~, ~:TEXT~) |
+| ~:DEPTH~ | integer | Recursion counter for loop prevention |
+
+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.

-* 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

+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)"`.
-5. Submit a PR outlining the architectural intent and the specific Literate changes.

+** 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.
+- The ~Scribe~ background worker distills chronological logs into structured Zettelkasten notes.
+- The ~Gardener~ continuously repairs broken links and flags orphaned nodes.
+
+* How Safety Works
+
+Passepartout enforces safety through ten deterministic gates. Every action the agent wants to take — reading a file, running a shell command, sending network traffic — passes through these gates before execution. Critically, all ten gates are pure Lisp functions: they cost zero LLM tokens to evaluate. Safety checking never touches your provider budget.
+
+** The Ten Safety Gates
+
+| Gate | What It Checks |
+|------+----------------|
+| Lisp syntax | Validates that any Lisp code is well-formed before evaluation |
+| Secret file paths | Blocks reads from known secret directories (~.ssh~, ~.env~, ~.aws~, etc.) |
+| Self-build core | Prevents modification of the agent's own source and build files |
+| Secret content | Scans text output for API keys, tokens, or credential patterns |
+| Vault secrets | Guards any secret stored in the encrypted vault |
+| Privacy tags | Respects ~@privacy:~ annotations on memory objects and files |
+| Privacy text leaks | Scans outgoing text for PII (emails, phone numbers, addresses) |
+| Shell safety | Blocks destructive commands (~rm -rf~, ~:(){:|:&};:~, ~mkfs~, ~dd~) |
+| Network exfiltration | Blocks outbound traffic carrying private data to unknown hosts |
+| High-impact actions | Catches system-level changes (package installs, service restarts, mount) |
+
+** Severity Tiers
+
+Each gate assigns a severity to the action it inspects:
+
+| Severity   | Behavior                                              |
+|------------+-------------------------------------------------------|
+| Catastrophic | Always blocked. No approval possible.                |
+| Dangerous    | Requires HITL approval. Generates a Flight Plan.    |
+| Moderate     | Allowed, but logged. The agent learns from the outcome. |
+| Harmless     | Always allowed. No logging overhead.                 |
+
+** What Happens When an Action Is Blocked
+
+When a gate blocks an action, the Dispatcher creates a Flight Plan — a structured record of what the agent wants to do, why it was blocked, and which gate triggered. The Flight Plan is presented to you for review. You can approve it (~/approve~), deny it (~/deny~), or ask the agent to clarify its intent (~/clarify~). Once you approve, the action executes immediately. Once you deny, the Dispatcher records the decision as a permanent rule and will never propose that action again.
+
+* Understanding Context and Focus
+
+Passepartout uses a foveal-peripheral context model, inspired by human vision. This is how the agent decides what to pay attention to in your Memex.
+
+** The Three Levels of Attention
+
+- ~/foveal/~ — What the agent reads deeply and reasons about right now. Anything you explicitly mention, plus the current focused project.
+- ~/peripheral/~ — What the agent knows exists (titles, summaries, metadata) but does not read in detail. Everything in scope.
+- ~/blind/~ — Outside scope. The agent cannot see or access it.
+
+** Focus Commands
+
+| Command             | Effect                                                  |
+|---------------------+---------------------------------------------------------|
+| ~/focus <project>~  | Set the agent's foveal attention to a project           |
+| ~/scope memex~      | Expand scope to everything in your Memex               |
+| ~/scope session~    | Narrow scope to just the current conversation           |
+| ~/scope project~    | Narrow scope to the focused project only               |
+| ~/unfocus~          | Clear the foveal focus; the agent sees everything at peripheral level |
+
+** The Focus Map
+
+The status bar displays a focus map — a compact representation of what the agent is "looking at." Projects in foveal view are highlighted; peripheral projects are dimmed. When you change focus, the map updates in real time so you always know the agent's current attention budget.
+
+* Skills and What They Do
+
+Skills are hot-reloadable modules that extend the agent's capabilities. Unlike core system files, a bug in a skill degrades the agent but does not kill it — skills can be repaired by the agent itself. Skills are organized into categories by function:
+
+** Core Pipeline
+The agent's cognitive loop: Perceive (consume input) → Reason (think with the LLM) → Act (execute tools). This is the central nervous system of the agent.
+
+** Security
+~Dispatcher~, ~Policy~, ~Permissions~, ~Validator~, ~Vault~. These skills enforce the safety gates, manage approval workflows, encrypt secrets, and verify that every action conforms to the rules you have set.
+
+** Channels
+~TUI~, ~CLI~, ~Telegram~, ~Signal~, ~Discord~, ~Slack~, ~Shell~. Each channel is a separate skill that handles I/O for a specific interface. All channels are equal citizens — the agent treats a message from Telegram identically to one typed in the TUI.
+
+** Programming
+~Lisp~, ~Org~, literate tools, ~REPL~, standards libraries. These skills allow the agent to write, evaluate, and reason about Lisp code, manage Org-mode documents, and tangle literate programs into runnable source.
+
+** Symbolic
+~Awareness~, ~Scope~, ~Events~, ~Config~, ~Memory~, ~Identity~, ~Time~. These skills manage the agent's internal state: what it knows about itself, what it remembers, how it configures its behavior, and how it tracks time and events.
+
+** Neuro
+~Provider~, ~Router~, ~Explorer~. These skills manage the LLM backends. The Provider skill abstracts each LLM API; the Router decides which provider to use based on cost, latency, and availability; the Explorer discovers new providers.
+
+** Embedding
+Backends for semantic search and native inference. These skills enable the agent to embed text, search your Memex by meaning rather than exact keyword, and run local inference without network calls.
+
+** Economics
+~Tokenizer~, ~Cost Tracker~, ~Token Economics~. These skills count tokens, estimate costs before making LLM calls, track spending across providers, and enforce budget limits.
+
+* The Tool System
+
+The agent has ten cognitive tools — discrete actions it can take to interact with your environment. Each tool maps to a specific capability.
+
+** Read-Only Tools
+
+| Tool              | What It Does                                |
+|-------------------+---------------------------------------------|
+| ~search-files~    | Search file contents with regex patterns    |
+| ~find-files~      | Find files by name using glob patterns      |
+| ~read-file~       | Read the contents of a file on disk         |
+| ~list-directory~  | List the contents of a directory            |
+| ~org-find-headline~ | Find a headline in an Org-mode file       |
+
+** Write Tools
+
+| Tool              | What It Does                                |
+|-------------------+---------------------------------------------|
+| ~write-file~      | Create or overwrite a file on disk          |
+| ~org-modify-file~ | Modify an Org-mode file structurally        |
+| ~run-shell~       | Execute a shell command                     |
+| ~eval-form~       | Evaluate a Lisp expression                  |
+| ~run-tests~       | Execute a test suite                        |
+
+** Auto-Approval
+
+Write tools are subject to safety-gate inspection. Read-only tools are auto-approved by default (though the agent still checks for secret-file reads). You can configure per-tool auto-approval in your ~.env~ file with the ~AUTO_APPROVE_TOOLS~ variable:
+
+#+begin_src bash
+# Auto-approve read-file and find-files (default)
+AUTO_APPROVE_TOOLS=read-file,find-files,list-directory,search-files
+#+end_src
+
+* Cost Tracking
+
+Every LLM call costs tokens, and tokens cost money. Passepartout tracks this transparently.
+
+** Token Budgets
+
+Set ~CONTEXT_MAX_TOKENS~ in your ~.env~ file to cap the total context window the agent may use per interaction:
+
+#+begin_src bash
+CONTEXT_MAX_TOKENS=128000
+#+end_src
+
+The agent will truncate older context rather than exceed this limit.
+
+** Per-Call Cost Tracking
+
+Before every LLM call, the Economics skill estimates the cost (prompt tokens + expected completion tokens) and checks it against your budget. After the call, it records actual usage. The status bar shows your session total.
+
+** The ~/cost~ Command
+
+Toggle cost display in the status bar with ~/cost~. When enabled, you'll see a running total like ~[$0.047]~ showing the estimated cost of the current session.
+
+** Per-Provider Pricing
+
+Different providers charge different rates. The Router skill is aware of this and will choose the cheapest viable provider for each call unless you pin a specific provider:
+
+#+begin_src bash
+# Pin to a specific provider
+PROVIDER_CASCADE=anthropic
+#+end_src
+
+** Prompt Prefix Caching
+
+Providers that support prefix caching (Claude via Anthropic, some OpenRouter models) automatically benefit from it. The agent reuses the system prompt prefix across calls, and the Economics skill tracks the cache-hit savings separately in the cost breakdown.
+
+* Session Control
+
+Passepartout maintains a session history with checkpointed memory snapshots. You can move backward and forward through your session state.
+
+** Undo and Redo
+
+| Command      | Effect                                                   |
+|--------------+----------------------------------------------------------|
+| ~/undo~      | Restore the memory to the state before your last action  |
+| ~/redo~      | Re-apply the last undone action                          |
+| ~/rewind <n>~ | Restore the memory to the state n actions ago           |
+
+** What Gets Restored
+
+A session rewind restores three things: file changes (files written or modified are reverted), memory objects (the agent's internal knowledge), and TODO states (the roadmap and task tracking). This means you can safely let the agent explore and experiment — if it goes down a wrong path, rewind and redirect.
+
+* Gate Trace Reference
+
+Below every agent message in the TUI, you'll see colored lines representing the safety-gate trace for that message. These show you exactly which gates ran on the agent's actions and what happened.
+
+| Symbol | Meaning                                                    |
+|--------+------------------------------------------------------------|
+| ~✓~    | Green — the gate passed. The action was allowed.            |
+| ~✗~    | Red — the gate blocked the action. The reason is shown.     |
+| ~→~    | Yellow — HITL approval required. A Flight Plan is pending.  |
+
+Press ~Ctrl+G~ to toggle gate trace visibility on and off. The most recent gate trace for your last interaction is always available via the ~/why~ command — type ~/why~ and the agent will display the full trace with explanations.
+
+* Tag System
+
+Passepartout uses an Org-mode tag system to annotate and control behavior. Tags are metadata appended to headlines and memory objects.
+
+** Severity Tags
+
+The ~@tag:severity~ tier controls how strictly the safety system handles a tagged item:
+
+| Tag              | Behavior                                                     |
+|------------------+--------------------------------------------------------------|
+| ~@tag:block~     | The tagged item is treated as catastrophic — always blocked  |
+| ~@tag:warn~      | The tagged item triggers HITL approval when accessed         |
+| ~@tag:log~       | Access is allowed but logged for audit                       |
+
+** Tag Categories
+
+Configure which tags trigger which behavior with the ~TAG_CATEGORIES~ environment variable:
+
+#+begin_src bash
+TAG_CATEGORIES=block:warn:log
+#+end_src
+
+** The ~/tags~ Command
+
+Type ~/tags~ to list all tags currently active in the agent's scope, along with their severity levels and the files or memory objects they apply to.
+
+* HITL Deep Dive
+
+When the Safety system blocks an action, a structured workflow begins. Understanding this workflow helps you make informed approval decisions quickly.
+
+** The Flight Plan Lifecycle
+
+1. /Trigger/: A gate rates an action Dangerous or Catastrophic, or a ~@tag:warn~ tag is encountered.
+2. /Plan/: The Dispatcher serializes the proposed action into a Flight Plan: what tool, what arguments, what file or command, which gate triggered.
+3. /Display/: The TUI shows a yellow prompt with the Flight Plan token (~HITL-ab12~).
+4. /Review/: Press ~Tab~ to expand the gate trace and see the full Flight Plan details.
+5. /Decision/: You type ~/approve HITL-ab12~ or ~/deny HITL-ab12~.
+6. /Execute or Discard/: Approved plans execute immediately. Denied plans are discarded.
+7. /Learn/: The Dispatcher increments its rule counter and records the decision as a permanent rule. If you denied an action, the Dispatcher will never propose it again.
+
+** Clarifying Questions
+
+If you are unsure why the agent wants to perform an action, you can ignore the Flight Plan prompt. After three retries without a decision, the agent escalates by injecting a ~/clarify~ message into the pipeline, asking the agent to explain its intent in plain language. You can then approve or deny with full context.
+
+** The Rule Counter
+
+The status bar shows ~[Rules: N]~ — the number of permanent rules the Dispatcher has learned from your decisions. Each approval or denial is a learning event. Over time, the Dispatcher builds a personalized safety profile that reflects your preferences: which actions you always approve, which you always deny, and which you want to review case by case.
+
+* TUI Keybinding Reference
+
+The TUI supports a rich set of keyboard shortcuts for efficient interaction.
+
+** Editing Keys

+* 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

+
+;; Author: Passepartout Project
+;; Version: 0.4.0
+;; Keywords: tools, processes, lisp
+;; URL: https://github.com/amrgharbeia/passepartout
+
+;;; Commentary:
+
+;; Connects to the Passepartout daemon on localhost:9105 via TCP.
+;; Speaks the framed plist protocol — 6-character hex length prefix
+;; followed by a prin1'd S-expression — identical to the TUI and CLI.
+;; The daemon does not know or care whether the client is the Croatoan
+;; TUI, the CLI, or Emacs.
+
+;; Framed protocol (per core-communication.org):
+;;   SEND: 6-char hex length + prin1'd plist
+;;   RECV: read 6-char header → parse hex length → read N bytes →
+;;         read-from-string (with read-eval nil on daemon side)
+
+;; Usage:
+;;   M-x passepartout RET        — connect to daemon, open response buffer
+;;   M-x passepartout-send-region — send selected region as user-input
+;;   M-x passepartout-send-buffer — send entire buffer

-#+AUTHOR: Agent
-#+FILETAGS: :harness:act:
-#+STARTUP: content
-#+PROPERTY: header-args:lisp :tangle act.lisp
-
-* Overview
-The Act stage dispatches approved actions to registered actuators. After the Probabilistic engine proposes and the Deterministic engine verifies, Act executes the approved action via the appropriate actuator (:cli, :tool, :system, :telegram, :signal, etc.). The actuator registry is extensible — skills can register new actuators at runtime.

-* Overview
-The *Context API* (Peripheral Vision) provides the opencortex with the ability to selectively prune and present its memory to the LLM. It implements a **Foveal-Peripheral model**, where the current task is shown in high detail (foveal), while the broader Memex structure is shown as a skeletal outline (peripheral).

-#+TITLE: System Diagnostic Doctor (doctor.org)
-#+AUTHOR: Agent
-#+FILETAGS: :harness:setup:diagnostic:
-#+STARTUP: content
-
-* Overview
-The *System Doctor* is the primary diagnostic utility for the OpenCortex. Its purpose is to transform opaque startup failures into actionable engineering reports. 
-
-By centralizing environment validation, we ensure that the "Brain" never attempts to boot in a compromised or incomplete state.
-
-* Phase A: Demand (Thinking)
-** The XDG Standard Rationale
-To ensure OpenCortex behaves as a first-class POSIX citizen, we adopt the **XDG Base Directory Specification**. This separates the system into four logical layers:
-
-1. **Configuration (`~/.config/opencortex`)**: User-editable settings and secrets.
-2. **Data (`~/.local/share/opencortex`)**: Tangled Lisp engine artifacts (immutable by user).
-3. **State (`~/.local/state/opencortex`)**: Dynamic persistence like brain snapshots.
-4. **Bin (`~/.local/bin`)**: The CLI shim for global invocation.
-
-** The Detection Invariant: Shell Probing
-Common Lisp's `getenv` is strictly typed in SBCL. The Doctor must ensure that missing variables are handled as logic failures, not type crashes. Furthermore, binary detection must use a shell probe (`command -v` or `which`) to account for varying `$PATH` inheritance between interactive and headless sessions.

-#+TITLE: The System Memory (memory.lisp)
-#+AUTHOR: Agent
-#+FILETAGS: :harness:memory:
-#+STARTUP: content
-#+PROPERTY: header-args:lisp :tangle memory.lisp
-
-* Overview
-The Memory module is the agent's live cognitive state — a set of Merkle-tree-versioned ~org-object~ instances stored in hash tables. Every perception, action, and decision is recorded here.
-
-Key structures:
-- ~*memory*~ — the primary object store, keyed by ID
-- ~*history-store*~ — immutable archive of all past object versions, keyed by SHA-256 hash
-- ~org-object~ — the universal data unit (id, type, attributes, content, vector embedding, parent, children, merkle hash)
-- ~ingest-ast~ — converts an Org-mode AST into ~org-object~ instances, computing Merkle hashes for integrity

-(defvar *history-store* (make-hash-table :test 'equal)
-  "Immutable Merkle-Tree versioning store mapping hashes to objects.")

-** Object Lookup (lookup-object)
-Retrieve a single object by its ID from the active memory store.
-#+begin_src lisp
-(defun lookup-object (id)
-  "Retrieves an org-object by ID from *memory*."
-  (gethash id *memory*))
-#+end_src
-
-** Object search (list-objects-with-attribute)
-Scan the entire memory store for objects whose attributes match a given key-value pair.
-#+begin_src lisp

-* Overview
-~package.lisp~ defines two things: the public API of the ~opencortex~ package (the export list, above), and the implementation of low-level utility functions and global state that don't belong in a specific pipeline stage or skill.
-
-The export list is the contract between the harness and all skills. Every function exported here is accessible to every skill via ~use-package~. Adding a symbol here is an API commitment; removing one is a breaking change.
-
-The implementation section includes:
-- ~proto-get~ — robust plist accessor used everywhere
-- Logging state (~*system-logs*~, ~*logs-lock*~)
-- Skill registry (~*skills-registry*~, ~defskill~)
-- Cognitive tool registry (~*cognitive-tools*~, ~def-cognitive-tool~)
-- Configuration variables (~*privacy-filter-tags*~, ~*secret-protected-paths*~, ~*secret-exposure-patterns*~)
-- Debugger hook

-** Package Implementation
-The package implementation section defines the low-level utilities and global state that are shared across all harness components and skills.
-
-*** Robust plist access (proto-get)
-Retrieves a value from a plist, checking both upper and lowercase keyword variants. This is needed because different components use different keyword conventions.
-#+begin_src lisp :tangle package.lisp

-The harness maintains a bounded ring buffer of log messages for inclusion in LLM context. Access is thread-safe via a lock.

-
-** Probabilistic Engine state
-~*probabilistic-backends*~ is the hash table mapping provider keywords to backend functions. ~*provider-cascade*~ is the ordered list of providers to try. ~*model-selector-fn*~ is an optional function that selects a model per request. ~*consensus-enabled-p*~ enables multi-provider agreement.

It discovers skill files in the skills directory, resolves their dependency order, loads them into jailed packages, exports their public symbols into the ~opencortex~ package, and provides the ~defskill~ macro that skills use to register themselves.
-
-Key concepts:
-- ~defskill~ — macro that registers a skill with its trigger, deterministic gate, and optional probabilistic prompt
-- ~def-cognitive-tool~ — macro that registers a tool the LLM can invoke
-- ~load-skill-from-org~ / ~load-skill-from-lisp~ — load a skill from a literate Org file or a pre-tangled Lisp file
-- ~topological-sort-skills~ — orders skills by their ~#+DEPENDS_ON:~ declarations
-- ~find-triggered-skill~ — returns the highest-priority skill whose trigger matches the current context
-
-The engine supports **hot-reload** — skills can be replaced at runtime without restarting the daemon.

-** Utility functions
-Helper functions used by the skill loader and other components.
-
-*** Cosine similarity
-Computes the cosine similarity between two numeric vectors. Used by the peripheral vision system for semantic relevance scoring.
-#+begin_src lisp
-(defun COSINE-SIMILARITY (v1 v2)
-  "Computes cosine similarity between two vectors."
-  (let* ((len1 (length v1)) (len2 (length v2)))
-    (if (or (zerop len1) (zerop len2))
-        0.0
-        (let* ((dot 0.0d0) (n1 0.0d0) (n2 0.0d0))
-          (dotimes (i (min len1 len2))
-            (let* ((x (coerce (elt v1 i) 'double-float)) (y (coerce (elt v2 i) 'double-float)))
-              (incf dot (* x y)) (incf n1 (* x x)) (incf n2 (* y y))))
-          (if (or (zerop n1) (zerop n2)) 0.0 (/ dot (sqrt (* n1 n2))))))))

-
-*** Secret masking
-Simple mask function and the vault memory hash table. Used by the Bouncer skill and credentials vault.
-#+begin_src lisp
-(defun VAULT-MASK-STRING (s) (declare (ignore s)) "[MASKED]")
-(defvar *VAULT-MEMORY* (make-hash-table :test 'equal))
-#+end_src
-
-** Skill data structures
-The ~skill~ struct holds all metadata about a loaded skill: its name, priority, dependencies, trigger function, probabilistic prompt generator, deterministic gate, and system prompt augmentor. The ~skill-entry~ struct tracks the loading state of each discovered skill file.
-#+begin_src lisp
-(defstruct skill name priority dependencies trigger-fn probabilistic-prompt deterministic-fn system-prompt-augment)
-#+end_src
-
-#+begin_src lisp
-(defvar *skills-registry* (make-hash-table :test 'equal))
-#+end_src
-
-#+begin_src lisp
-(defvar *skill-catalog* (make-hash-table :test 'equal)
-  "Tracks all discovered skill files and their loading state.")
-#+end_src
-
-#+begin_src lisp
-(defstruct skill-entry filename (status :discovered) error-log (load-time 0))
-#+end_src
-
-** Skill discovery (find-triggered-skill)
-Iterates the registry and returns the highest-priority skill whose trigger function matches the current context. Only skills with a probabilistic prompt are considered (skills that are purely deterministic don't need LLM intervention).
-#+begin_src lisp
-(defun find-triggered-skill (context)
-  "Returns the highest priority skill whose trigger matches context."
-  (let ((triggered nil))
-    (maphash (lambda (name skill)

-               (when (and (skill-probabilistic-prompt skill)
-                          (ignore-errors (funcall (skill-trigger-fn skill) context)))
-                 (push skill triggered))) 
-              *skills-registry*)
-    (first (sort triggered #'> :key #'skill-priority))))
-#+end_src
-
-** Skill registration macro (defskill)
-The primary API for skills. Each skill file calls this once to register itself. The macro creates a ~skill~ struct and stores it in ~*skills-registry*~ keyed by the skill's name.
-#+begin_src lisp
-(defmacro defskill (name &key priority dependencies trigger probabilistic deterministic system-prompt-augment)
-  "Registers a new skill. NAME is a keyword. TRIGGER is a function (context) → bool."
-  `(setf (gethash (string-downcase (string ,name)) *skills-registry*)
-         (make-skill :name (string-downcase (string ,name)) 
-                    :priority (or ,priority 10) 
-                    :dependencies ',dependencies

-#+end_src

-** Dependency resolution (resolve-skill-dependencies)
-Recursively resolves all transitive dependencies for a given skill, returning an ordered list. Uses a standard topological sort with cycle detection (a ~seen~ set prevents infinite recursion).
-#+begin_src lisp
-(defun resolve-skill-dependencies (skill-name)
-  "Resolves transitive dependencies. Returns list of skill names in dependency order."
-  (let ((resolved nil) (seen nil))

-                     (dolist (dep (skill-dependencies skill)) (visit dep))))

-#+TITLE: OpenCortex TUI Client (Standalone)
-#+STARTUP: content
-#+FILETAGS: :tui:ux:client:
-#+PROPERTY: header-args:lisp :tangle tui-client.lisp
-
-* Overview
-The TUI Client is a standalone ncurses application (built on Croatoan) that connects to the daemon via TCP. It provides a split-pane interface: a scrollable chat history window and a fixed input line at the bottom. Connected to the daemon at ~localhost:9105~, it sends user input as framed protocol messages and displays responses as they arrive from the daemon's background reader thread.

+The CLI Gateway is the simplest interface to Passepartout — raw stdin/stdout over TCP. It connects to the daemon's framed protocol and translates between terminal input/output and the plist-based communication format. No TUI, no ncurses, no dependencies beyond a TCP socket. Every other gateway (TUI, Emacs, Telegram) builds on this same protocol.

+* Channel Discord
+
+Extracted from gateway-messaging in v0.5.0. Isolated platform — Discord-specific poll and send logic.
+
+* Overview
+
+The Discord channel provides bidirectional communication via the Discord REST API
+and Gateway WebSocket. Messages received from Discord channels are injected into
+the cognitive pipeline as ~:user-input~ signals with ~:source :discord~. Outbound
+messages route through the actuator registry when the pipeline targets ~:discord~.
+
+The channel uses two functions: ~discord-poll~ (inbound sensor, REST polling)
+and ~discord-send~ (outbound actuator, REST POST). Both retrieve the bot token
+from the credentials vault (~vault-get-secret :discord~). HITL commands are
+intercepted before injection so approval flows work identically across all channels.
+
+** Contract
+
+1. (discord-get-token): returns the Discord bot token from the vault
+   (via ~vault-get-secret :discord~), or nil if not configured.
+2. (discord-poll): polls configured channels via GET /channels/{id}/messages,
+   injects each non-bot message as a ~:user-input~ stimulus with
+   ~:source :discord~. Handles JSON parse failures and API errors
+   gracefully. HITL commands are intercepted before injection.
+3. (discord-send action context): sends a message via POST /channels/{id}/messages.
+   Extracts ~:channel-id~ and ~:text~ from the action plist. Uses bot token
+   authentication. Logs send failures without crashing the pipeline.

+
+* Overview: The Physical Actuator
+
+The Shell Actuator is the agent's hand in the physical world. Given a shell command, it executes it via ~bash -c~ and returns the output. This is how the agent installs packages, reads files, runs scripts, and interacts with any Unix tool.
+
+Because shell execution is the highest-risk operation in the system, the Shell Actuator is protected by multiple safety layers:
+1. The Dispatcher's shell safety gate blocks destructive commands (~rm -rf /~, ~dd~, ~mkfs~)
+2. The Dispatcher's injection gate blocks backtick and ~$()~ patterns
+3. The Dispatcher's network exfil gate blocks connections to unwhitelisted hosts
+4. The actuator enforces a timeout (default 30s) so hanging commands don't freeze the agent
+5. The actuator caps output (default 100KB) so infinite output doesn't exhaust memory
+6. (v0.4.3) When ~bwrap~ (Bubblewrap) is available, commands execute inside a Linux namespace sandbox with network and IPC isolation
+
+** Contract
+
+1. (bwrap-available-p): returns T if ~bwrap~ is installed and usable, NIL otherwise.
+   Cached at load time via ~which bwrap~.
+2. (bwrap-wrap-command cmd timeout memex-dir): returns a command list suitable for
+   ~uiop:run-program~ — wraps ~cmd~ in a ~bwrap~ sandbox with ~--unshare-net~,
+   ~--unshare-ipc~, ~--ro-bind~ for system dirs, and ~--bind~ for the memex and /tmp.
+3. (actuator-shell-execute action context): when ~bwrap~ is available, wraps the
+   command through the sandbox. When ~bwrap~ is unavailable, falls back to the
+   existing ~timeout bash -c~ behavior.

+* Channel Signal
+
+Extracted from gateway-messaging in v0.5.0. Isolated platform — Signal-specific poll and send logic.
+
+* Overview
+
+The Signal channel provides bidirectional communication via the ~signal-cli~ CLI tool.
+Messages received from Signal contacts are injected into the cognitive pipeline
+as ~:user-input~ signals with ~:source :signal~. Outbound messages route through
+the actuator registry when the pipeline targets ~:signal~.
+
+The channel uses two functions: ~signal-poll~ (inbound sensor) and ~signal-send~
+(outbound actuator). Both retrieve the Signal account identifier from the
+credentials vault. HITL commands (~/approve~, ~/deny~) are intercepted before
+injection so approval flows work identically across all channels.
+
+** Contract
+
+1. (signal-get-account): returns the Signal phone number from the vault
+   (via ~vault-get-secret :signal~), or nil if not configured.
+2. (signal-poll): queries ~signal-cli receive --json~ for new messages,
+   injects each non-system message as a ~:user-input~ stimulus with
+   ~:source :signal~. Handles JSON parse failures and network errors
+   gracefully (logs and continues). HITL commands are intercepted before
+   injection.
+3. (signal-send action context): sends a message via ~signal-cli send~.
+   Extracts ~:chat-id~ and ~:text~ from the action plist. Logs send
+   failures without crashing the pipeline.

+#+TITLE: Passepartout TUI — View
+#+PROPERTY: header-args:lisp :tangle /home/user/.local/share/passepartout/lisp/channel-tui-view.lisp
+
+* View
+
+|Pure render functions. Each takes the cl-tty backend and current state.
+|State is read via ~(st :key)~ — no mutation here.
+
+** Contract
+
+1. (view-status fb w h): no-op. Status bar is a clean black line.
+2. (view-chat fb w h): renders scrolled chat messages. User messages
+   get amber left border (│), agent messages no border, streaming
+   agent gets grey left border. Gate traces/tool calls use ╎ prefix.
+3. (view-input fb w h): renders expanding light grey input box,
+    multi-line word-wrapped prompt, hint bar at h-2. Text and cursor
+   rendered by cl-tty.input text-input's render method.
+4. (view-sidebar fb w h): renders sidebar panels using ~sidebar-lines~.
+5. (sidebar-lines): builds a flat list of (text . color-key) pairs for
+   the sidebar: gate trace, rules, cost, files, version.
+6. (msg->pairs msg index bordered-w unbordered-w is-search): converts
+    a message to renderable ~(border border-color text text-color &optional bg)~
+    lines. Handles markdown, gate trace, tool calls, search highlight.
+7. (render-pair fb hpad y pair): draws one message line pair.
+8. (redraw fb w h): wraps view-status/chat/input in begin-sync/end-sync,
+   dispatches per dirty flags, fills global :bg first.
+9. ~cl-tty.box:char-width~ for terminal column width.
+   ASCII < 128 = 1. CJK, fullwidth, emoji = 2. Combining marks = 0.
+   Tab = 8. Used by cl-tty.box:word-wrap for accurate line counting.
+10. (sidebar-visible-p w): returns T if sidebar should show given width W
+    and current :sidebar-mode (:auto >120, :visible always, :hidden never).
+
+** Status Bar
+
+The status bar, as of v0.4.0, renders Passepartout's three differentiator
+visualizations — data only available because of the deterministic gate
+architecture:
+
+- *Rule counter* (~Rules:N~): the number of pending HITL actions from the
+  Dispatcher's ~*hitl-pending*~ hash table. The user watches this tick up
+  as they teach the agent their preferences through approve/deny decisions.
+- *Focus map* (~[Focus: <id>]~): the foveal focus from the daemon's signal
+  context. Shows the user what the agent is currently looking at.
+- *Gate trace* (not rendered in status bar — attached to individual
+  messages via ~:gate-trace~ field for future collapsible rendering per
+  message).
+
+All three enrichments cost 0 LLM tokens — they are daemon-state queries
+that the TUI actuator attaches to the response plist before transmission.

+
+* Overview: Architectural Intent
+
+The Act stage is where cognition meets reality. After the Probabilistic engine proposes an action and the Deterministic engine verifies it, Act executes it through the appropriate actuator.
+
+An actuator is a function that takes (action context) and performs a physical operation: send a message to the TUI, execute a shell command, call a Telegram API, write to a file. Actuators are registered in a global hash table (~*actuator-registry*~) and dispatched by name.
+
+The key architectural choice: **actuators are not privileged**. The same dispatch mechanism that routes to :shell or :file also routes to :telegram or :signal. There is no special handling for dangerous actuators — safety is enforced at the Reason stage by the deterministic engine, not by Act. This means:
+
+1. Adding a new actuator requires no changes to the core — just register it
+2. Safety is centralized in the deterministic gates, not scattered across actuator implementations
+3. Every actuator benefits from the same security checks (the Dispatcher, the Policy)
+
+** Why Dispatch-Action Verifies Again?
+
+The Reason stage already ran every proposed action through the deterministic engine. So why does ~loop-gate-act~ call ~cognitive-verify~ again?
+
+Because a skill's deterministic gate runs during Reason, but between Reason and Act, the action might have been transformed by the pipeline (metadata added, format normalized). The last-mile verification catches any transformation that might have introduced an unsafe property. It's the same philosophy as "trust but verify" — the second check is cheap and catches a class of bugs that would otherwise be silent data corruption.
+
+** Contract
+
+1. (loop-gate-act signal): the final pipeline stage. Handles HITL
+   ~:approval-required~ (suspends action), runs last-mile
+   ~cognitive-verify~ on approved actions, dispatches via
+   ~action-dispatch~, sets ~:status :acted~, returns feedback.
+2. (act-gate signal): thin alias for ~loop-gate-act~.
+3. (action-dispatch approved signal): routes approved actions to
+    registered actuators by ~:target~ keyword.
+ 4. (tui-enrich-response action context): enriches the outgoing action
+    plist with sidebar fields — ~:block-counts~, ~:context-usage~,
+    ~:modified-files~, ~:session-cost~ (v0.8.0) — plus existing
+    ~:rule-count~ and ~:foveal-id~ (v0.4.0). Each field is
+    ~fboundp~-guarded; missing skills produce nil. Called from the
+    ~:tui~ actuator lambda.

+** Actuator Configuration
+
+~*actuator-default*~ determines where actions go when no explicit target is specified. Defaults to ~:cli~.
+
+~*actuator-silent*~ lists actuator targets that don't generate tool-output feedback. For example, sending a message to the CLI or Emacs doesn't need to produce a tool-output event — the user can see the message directly. This prevents redundant feedback loops.

+
+** TUI Differentiator Enrichment (v0.4.0, extended v0.8.0)
+
+The TUI actuator is the last point in the pipeline before the response leaves the daemon. It enriches the action plist with fields that power the TUI's differentiator visualizations:
+
+- ~:rule-count~ = ~(hash-table-count *hitl-pending*)~ — the number of pending HITL actions. The user watches this counter tick as they teach the agent their preferences. (v0.4.0)
+- ~:foveal-id~ = the current foveal focus from the signal context — enables the TUI's focus map status line. (v0.4.0)
+- ~:gate-trace~ — already attached by ~cognitive-verify~, flows through the action plist unchanged. (v0.4.0)
+
+v0.8.0 adds four sidebar fields via ~fboundp~ guards — same pattern as
+~core-reason.lisp~'s calls into token-economics, awareness, and time skills.
+Each field degrades gracefully to nil when its source skill is not loaded:
+
+- ~:block-counts~ = ~(dispatcher-block-counts-summary)~ — per-gate block tallies from ~security-dispatcher~. Powers the sidebar's Protection panel.
+- ~:context-usage~ = ~(context-usage-percentage)~ — token budget percentage from ~token-economics~. Powers the sidebar's Context gauge.
+- ~:modified-files~ = ~(tool-modified-files-summary)~ — files modified this turn from ~programming-tools~. Powers the sidebar's Files panel.
+- ~:session-cost~ = ~(cost-session-summary)~ — cumulative cost data from ~cost-tracker~. Powers the sidebar's Cost panel.
+
+The enrichment is added inside the existing ~:tui~ actuator lambda (one block
+after the ~:rule-count~ and ~:foveal-id~ enrichment). No new actuator is
+registered; no new ASDF component is added. The contract is: each field
+arrives via ~fboundp~ guard and is silently nil when unavailable.
+
+** Action Dispatch (action-dispatch)
+
+Routes an approved action to its registered actuator. The target is resolved in priority order:
+
+1. The explicit ~:target~ field on the action
+2. The source of the original signal (reply to the sender)
+3. The default actuator (~:cli~)
+
+Heartbeats are silently dropped here — they should never generate an actuation.

+* Overview: Architectural Intent
+
+The Manifest is the ASDF system definition for Passepartout. It defines what files belong to the harness, which external libraries are required, and how the test infrastructure is organized.
+
+The ~passepartout.asd~ file tangled from this manifest is what ~ql:quickload :passepartout~ reads to load the system. The files are loaded in the order listed here — dependencies first, then each pipeline stage in order.
+
+* Implementation
+
+** Main System
+
+The core system. The combined ~:depends-on~ list pulls in every external library the agent needs: networking (usocket, dexador, hunchentoot), concurrency (bordeaux-threads), utilities (uiop, cl-ppcre, cl-json, str), security (ironclad), and configuration (cl-dotenv, uuid).
+
+Components are loaded in sequence (~:serial t~): package first (defines the public API), then skills (does the defskill macro), then communication (defines the protocol), then memory (defines org-object), then context (defines peripheral vision), then each pipeline stage in order (perceive, reason, act), then doctor (diagnostics), then loop (orchestration).

+Tests are embedded directly in each module's source file — see the `* Test Suite` section at the end of each `.org` file. No separate test system is needed.

+
+The TUI is a standalone system that depends on cl-tty (pure CL terminal UI) in addition to the core system. It's loaded separately because it requires a terminal and is not needed for daemon-mode operation.

+#+TITLE: The System Memory (memory.lisp)
+#+AUTHOR: Agent
+#+FILETAGS: :harness:memory:
+#+STARTUP: content
+#+PROPERTY: header-args:lisp :tangle /home/user/.local/share/passepartout/lisp/core-memory.lisp
+
+* Overview: Architectural Intent
+
+The Memory module is the cognitive bedrock of Passepartout. It is not a database; it is the agent's live, active brain state. Every perception, every action, every decision is recorded here.
+
+Traditional architectures rely on external databases (SQLite, vector DBs, JSON files) which introduce I/O latency, structural impedance, and serialization overhead. Passepartout chooses a different path: the **Single Address Space**. By treating the entire knowledge base as a graph of Lisp pointers in RAM, we achieve microsecond recollection and total structural transparency.
+
+The memory system has three layers:
+1. **Active memory** (~*memory-store*~) — a hash table mapping IDs to ~memory-object~ instances. This is what the agent queries during reasoning.
+2. **Immutable history** (~*memory-history*~) — an append-only hash table keyed by SHA-256 Merkle hash. Every version of every object that has ever existed is preserved here.
+3. **Snapshot stack** (~*memory-snapshots*~) — point-in-time copies of active memory for rollback recovery. Up to 20 snapshots are retained.
+
+** Why Merkle Hashes?
+
+Every ~memory-object~ carries a ~hash~ field computed from its ID, type, attributes, content, and children. This hash is deterministic: the same data always produces the same hash.
+
+The hash serves three purposes:
+1. **Integrity verification** — detect corruption or tampering
+2. **Deduplication** — if an object already exists in history, we reuse the existing entry
+3. **Change detection** — compare hashes to find what changed between snapshots
+
+** Why Snapshots Instead of Git?
+
+Git tracks changes to files. Passepartout tracks changes to live memory state. The snapshot system captures the entire active memory at a point in time, enabling full rollback to any previous state. This is necessary because:
+
+1. The agent modifies memory continuously (learning, noting, deciding) — there's no discrete "commit" boundary
+2. Memory corruption from a bad LLM output can affect multiple objects — snapshot rollback restores all of them atomically
+3. Git can't snapshot the running Lisp image's hash tables
+
+The tradeoff is memory usage: each snapshot is a deep copy of every object in active memory. 20 snapshots means 20x the active memory size. For a typical knowledge base of 10,000 objects, this is manageable (~100MB for 20 snapshots).
+
+** Contract
+
+1. (ingest-ast ast &key scope): stores AST nodes in ~*memory-store*~.
+   Detaches children, gives each an ID, computes Merkle hash, and
+   populates the ~:vector~ slot via ~embeddings-compute~. Returns the
+   root ID string.
+2. (memory-object-hash object): returns the SHA-256 Merkle hash of the
+   object's content. Hash is deterministic — same content → same hash.
+3. (memory-object-get id): retrieves a stored object by ID, or nil.
+4. (snapshot-memory): deep-copies ~*memory-store*~ to ~*memory-snapshots*~.
+5. (rollback-memory snap-index): restores ~*memory-store*~ from a snapshot.

+
+* Overview: Architectural Intent
+
+~package.lisp~ defines two things: the public API of the ~passepartout~ package (the export list), and the implementation of low-level utility functions and global state that don't belong in a specific pipeline stage or skill.
+
+The export list is the contract between the harness and all skills. Every function exported here is accessible to every skill via ~use-package~. Adding a symbol here is an API commitment; removing one is a breaking change.
+
+The implementation section includes:
+- ~proto-get~ — robust plist accessor used everywhere in the pipeline
+- Logging state (~*log-buffer*~, ~*log-lock*~) — bounded ring buffer for LLM context
+- Skill registry (~*skill-registry*~, ~defskill~) — all loaded skills live here
+- Cognitive tool registry (~*cognitive-tool-registry*~, ~def-cognitive-tool~, ~cognitive-tool-prompt~)
+- Telemetry tracking (~*telemetry-table*~, ~telemetry-track~) — performance metrics per skill
+- Debugger hook — replaces raw SBCL debugger with a friendly error message
+
+* Implementation
+
+** Package Definition and Export List
+The export list is organized by source module so a contributor can find
+where to add new exports:

+#+TITLE: Stage 1: Perceive (perceive.lisp)
+#+AUTHOR: Agent
+#+FILETAGS: :harness:perceive:
+#+STARTUP: content
+#+PROPERTY: header-args:lisp :tangle /home/user/.local/share/passepartout/lisp/core-perceive.lisp
+
+* Overview: Architectural Intent
+
+The Perceive stage is the sensory cortex of Passepartout. It receives raw stimuli from diverse sources — terminal input, Emacs buffers, Telegram messages, Signal chats, heartbeat clocks, shell command outputs — and normalizes them into a single Signal format that the rest of the pipeline can process.
+
+Each source has its own format and protocol. The CLI sends raw text. Emacs sends AST diffs. Telegram sends JSON. Without normalization, every downstream component (Reason, Act) would need to understand every input format. With normalization:
+
+1. The gateway layer (CLI, Emacs, Telegram, Signal) just sends raw messages
+2. Perceive transforms them into Signals regardless of origin
+3. Reason and Act work with a single, consistent plist format
+4. Adding a new gateway requires gateway code only — no changes to core
+
+This is the "thin harness, fat skills" principle applied to input processing. The harness does the minimal normalization needed to produce a uniform Signal; the actual interpretation is left to skills.
+
+** Why the Async/Sync Split?
+
+Perceive handles two kinds of stimuli:
+- **Synchronous** (user input, chat messages) — these must be processed in order, one at a time, because each depends on the state left by the previous one
+- **Asynchronous** (heartbeats, background sensor readings, delegation results) — these can be processed in parallel because they don't depend on user intent
+
+The `*loop-async-sensors*` list defines which sensor types are processed in dedicated threads. Everything else goes through the main synchronous pipeline.
+
+The depth limit prevents runaway recursive loops. A signal that generates another signal that generates another signal can infinite-loop. If depth exceeds a threshold (10), the signal is silently dropped rather than processed. This is the metabolic loop's circuit breaker.
+
+** Contract
+
+1. (loop-gate-perceive signal): normalizes sensory input. Routes by
+   sensor type (~:buffer-update~, ~:point-update~, ~:interrupt~,
+   ~:approval-required~) and signal type (~:EVENT~, ~:RESPONSE~).
+   Sets ~:status :perceived~ on completion. Returns the signal.
+2. (perceive-gate signal): thin alias for ~loop-gate-perceive~.
+
+* Implementation
+
+** Package Context
+#+begin_src lisp
+(in-package :passepartout)
+#+end_src
+
+** Interrupt Flag
+
+A global interrupt flag that can be set by any signal. When set, the metabolic loop should stop processing and clean up. This is used for graceful shutdown: a SIGINT or /exit command sets the flag, and the loop exits at the next cycle boundary.
+
+;; REPL-VERIFIED: 2026-05-03T13:00:00
+#+begin_src lisp
+(defvar *loop-interrupt* nil)
+#+end_src
+
+** Scope Resolver
+
+A hook for the context-manager skill to register its ~current-scope~
+function. When set, the perceive gate passes the current context scope
+to ~ingest-ast~ so ingested objects are tagged and queryable by scope.
+Defaults to ~nil~ meaning all objects are ingested as ~:memex~.
+
+;; REPL-VERIFIED: 2026-05-03T14:00:00
+#+begin_src lisp
+(defvar *scope-resolver* nil
+  "If set, function returning current scope keyword. Used by perceive gate.")
+#+end_src
+
+** Sensor Configuration
+
+~*loop-async-sensors*~ lists the sensor types that should be processed in their own threads. Currently, ~:chat-message~, ~:delegation~, and ~:user-command~ are async because they don't block the main reasoning loop — the agent can process a Telegram message while waiting for the user's next input.
+
+~*loop-focus-id*~ tracks what the user is currently looking at in Emacs. When the user moves their cursor to a different Org headline, the buffer-update signal updates this ID. The Reason stage uses it to build the foveal-peripheral context model: the current headline gets full detail, everything else gets a skeletal outline.
+
+;; REPL-VERIFIED: 2026-05-03T13:00:00
+#+begin_src lisp

+#+begin_src lisp
+(defvar *loop-focus-id* nil
+  "The Org ID of the node the user is currently interacting with.")
+#+end_src
+
+** Pre-Reason Handler Registry
+
+Skills register handlers for custom sensors here. When a signal arrives
+with a registered sensor, the handler is called in the perceive gate,
+before the signal reaches the LLM. The handler receives the full signal
+and returns T if the signal was consumed (don't continue to reason)
+or nil if processing should proceed normally.
+
+*** Pre-Reason Handler Hash Table

+;; REPL-VERIFIED: 2026-05-03T13:00:00

+#+begin_src lisp
+(defun register-pre-reason-handler (sensor fn)
+  "Registers FN to handle signals with SENSOR in the perceive gate.
+FN receives (signal) and returns T if consumed, nil to continue."
+  (setf (gethash sensor *pre-reason-handlers*) fn))
+#+end_src
+
+** Stimulus Injection (stimulus-inject)
+
+This is the entry point that gateways call to send a message into the cognitive pipeline. It sets metadata (source, session ID, reply stream), decides whether the stimulus should be processed synchronously or on a background thread, and wraps the whole thing in error recovery so that no single bad stimulus can crash the system.
+
+The error recovery uses Common Lisp's restart system. If any error occurs during processing, a `skip-event` restart is available. The handler displays the error, then invokes `skip-event` which drops the stimulus and continues. This is the "fail open" safety model — better to drop one message than to crash the entire agent.

+#+end_src
+
+** Perceive Gate (loop-gate-perceive)
+
+The perceive gate is the first stage of the metabolic pipeline. It receives a normalized signal and routes it based on the event type:
+
+- ~:EVENT~ with ~:buffer-update~ — an Emacs buffer changed (new Org headline created, text edited). The change is ingested into memory so the agent has the latest state.
+- ~:EVENT~ with ~:point-update~ — the user moved their cursor to a different headline. The foveal focus is updated, and the node at the cursor is ingested at higher priority.
+- ~:EVENT~ with ~:interrupt~ — the user requested an interrupt. The interrupt flag is set.
+- ~:RESPONSE~ — an action completed. The gate logs the result status.
+
+All signals get tagged with their processing stage (`:status :perceived`) and the current foveal focus before being passed to the Reason stage.

+#+TITLE: The Metabolic Loop (loop.lisp)
+#+AUTHOR: Agent
+#+FILETAGS: :harness:loop:
+#+STARTUP: content
+#+PROPERTY: header-args:lisp :tangle /home/user/.local/share/passepartout/lisp/core-pipeline.lisp
+
+* Overview: Architectural Intent
+
+The Metabolic Loop is the cranial nerve reflex of Passepartout. While skills provide specialized intelligence, the loop provides the fundamental rhythm of existence: the continuous processing of signals from perception through cognition to action.
+
+Every signal flows through three stages:
+1. **Perceive** — normalize raw input into a standard Signal format
+2. **Reason** — think (LLM) then verify (deterministic gates)
+3. **Act** — dispatch the approved action to the appropriate actuator
+
+If a stage produces a new signal (e.g., the Act stage produces a tool-output event), that signal feeds back into Perceive and the loop continues. This is how the agent has multi-step conversations: each LLM response produces an action, which produces a tool output, which feeds back as a new perception, which triggers the next reasoning cycle.
+
+** Why Separate Stages?
+
+A single function that called the LLM, checked safety, and executed the result would be simpler to write. But it would be impossible to:
+- Test each stage independently (a bug in the LLM call would block safety testing)
+- Insert new stages between P and R or R and A (adding consensus means adding a gate in the middle)
+- Recover from failures mid-pipeline (an LLM timeout shouldn't prevent safety checks on the next cycle)
+
+The stage separation is the functional equivalent of the "thin harness" principle: each stage is a pure function that transforms a signal. The loop is the composition of these functions.
+
+** Why the Depth Limit?
+
+A signal that generates another signal that generates another signal can infinite-loop. The depth limit (max 10) prevents this. If depth exceeds 10, the signal is silently dropped. This is the metabolic loop's circuit breaker.
+
+The three-tier error recovery model, now backed by a condition hierarchy
+that skills can hook into via ~handler-bind~:
+
+1. **Transient errors** (tool failures, network timeouts) — recoverable, generate a :loop-error signal at higher depth for retry. Use the ~skip-signal~ or ~use-fallback~ restart.
+2. **Critical errors** (undefined functions, malformed data) — require memory rollback to the last snapshot.
+3. **Recursive loops** (signals generating more signals indefinitely) — depth limit enforcement.
+
+Condition types available for structured error handling:
+- ~pipeline-error~ — any Perceive→Reason→Act failure
+- ~llm-error~ — provider timeout, cascade exhaustion, API error (slots: provider, cascade, attempt-count)
+- ~gate-error~ — dispatcher blocked a proposed action (slots: gate-name, rejected-action)
+- ~budget-error~ — session cap exceeded (slots: remaining, requested)
+- ~protocol-error~ — malformed message or framing failure
+
+** Contract
+
+1. (loop-process signal): the full pipeline loop — Perceive → Reason
+   → Act. Enforces depth limit (10). Catches errors with rollback and
+   ~:loop-error~ re-injection on non-terminal errors below depth 2.
+   Establishes restart options: ~skip-signal~ (drop the event),
+   ~use-fallback text~ (inject canned response), ~abort-pipeline~
+   (clean exit). Skills can invoke these restarts from ~handler-bind~
+   clauses on the condition hierarchy.
+2. (process-signal signal): thin alias for ~loop-process~.
+3. (diagnostics-startup-run): runs health check on startup, sets
+   ~*system-health*~ to ~:healthy~, ~:degraded~, or ~:unhealthy~.
+4. *passepartout-error* condition hierarchy: ~pipeline-error~,
+   ~llm-error~ (provider, cascade, attempt-count slots), ~gate-error~
+   (gate-name, rejected-action slots), ~budget-error~ (remaining,
+   requested slots), ~protocol-error~ (raw-message slot). All carry a
+   ~:message~ string via the root ~passepartout-error~.
+
+* Implementation
+
+** Package Context
+#+begin_src lisp
+(in-package :passepartout)
+#+end_src
+
+** Error Condition Hierarchy
+
+The pipeline defines a condition hierarchy so callers can distinguish
+failure modes without inspecting raw error strings. Every pipeline
+condition carries structured slots for telemetry and restart selection.
+
+Skills install ~handler-bind~ for specific conditions (e.g., a provider
+health monitor that records ~llm-error~ failures per backend). The
+restarts registered in ~loop-process~ enable structured recovery:
+skip the signal, retry with a modified prompt, inject a fallback
+response, or abort the cycle.

+** Core Engine (loop-process)
+
+The entry point to the metabolic pipeline. Each cycle runs Perceive → Reason → Act. If Act produces feedback (a new signal), the loop continues with that signal at the same depth.
+
+The function handles four failure modes:
+- **Depth exceeded**: signal dropped, nil returned
+- **Interrupt flag**: graceful shutdown, nil returned
+- **Handler error**: caught by handler-case, logged, and depending on the sensor type and depth:
+  - Normal errors at low depth → memory rollback + retry as :loop-error
+  - :loop-error and :tool-error at any depth → dropped (avoids infinite retry loops)
+  - High-depth errors (depth > 2) → dropped (avoids cascading failures)
+- **Unhandled error**: the handler-case catches everything, preventing any single bad signal from crashing the agent
+

+** Heartbeat Mechanism
+
+The heartbeat is a background thread that fires every N seconds (configurable via ~HEARTBEAT_INTERVAL~ env var, default 60). On each tick, it:

+1. Increments the save counter and saves memory to disk when the counter exceeds the auto-save interval (default 300s)
+2. Injects a ~:heartbeat~ signal into the pipeline
+
+The heartbeat signal is how background skills (Gardener, Scribe) get triggered without user input. These skills have triggers that match ~:sensor :heartbeat~ and run maintenance tasks during idle cycles.

+
+* Overview: Architectural Intent
+
+The Reason stage is the cognitive heart of Passepartout. It takes a normalized signal from Perceive and produces an approved action for Act. This is where the two engines — probabilistic (LLM) and deterministic (Lisp logic) — collaborate.
+
+The design is shaped by one non-negotiable constraint: **the LLM must never touch the actuators directly.** Every action the LLM proposes must pass through a deterministic verification gate that has the final say. This is what separates Passepartout from every other AI agent: the creative brain suggests, but the logical brain decides.
+
+** The Probabilistic-Deterministic Split
+
+An LLM is a statistical engine. Given enough context, it is remarkably good at translation, generation, and pattern matching. But it cannot be trusted with authority because hallucination is a *fundamental property* of probabilistic inference — the model generates the most likely continuation, not the correct one.
+
+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
+- The deterministic engine receives those structured representations and evaluates them against formal invariants
+- The LLM never reads a file, never executes a command, never modifies memory — it generates proposals
+
+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.
+
+** Why Plists for Communication?
+
+Every message in the Reason pipeline is a property list (plist):
+
+  (TYPE :REQUEST TARGET :CLI PAYLOAD (ACTION :MESSAGE TEXT "Hello"))
+
+A plist is simultaneously:
+- Human-readable text
+- Machine-parseable data structure
+- Executable Lisp code
+
+This is not a cosmetic choice. It means the reasoning pipeline can generate, modify, and execute its own communication protocol without external parsing libraries. There is no JSON encoder, no schema validator, no serialization layer between the two engines. They speak the same language because they *are* the same language.
+
+** Contract
+
+1. (cognitive-verify proposed-action context): runs all registered
+   deterministic gates sorted by priority. Returns a rejection plist
+   (~:LOG~ or ~:EVENT~) if any gate blocks the action, an
+   ~:approval-required~ event if a gate requires HITL, or the action
+   (potentially modified) if it passes.
+2. (loop-gate-reason signal): the full reason pipeline — only processes
+   ~:user-input~ and ~:chat-message~ sensors. Runs ~think~ to generate
+   a candidate, then ~cognitive-verify~ to gate it. Retries up to 3
+   times on rejection. Sets ~:status :reasoned~ on completion.
+3. (reason-gate signal): thin alias for ~loop-gate-reason~.
+4. (backend-cascade-call prompt): iterates ~*provider-cascade*~ calling
+   each backend's handler until one succeeds. Returns the LLM content
+   string, or a ~:LOG~ failure if all backends are exhausted.
+5. (json-alist-to-plist alist): converts a JSON alist (from
+   ~cl-json:decode-json-from-string~) to a keyword-prefixed plist.
+   String keys → upcased keywords. Nested alists recurse into plists.
+   JSON arrays (lists whose first element is not a cons) pass through.
+   Scalars and nil pass through.
+6. (think-assemble-prompt context): returns three values —
+   ~system-prompt~ (the full prompt string), ~raw-prompt~ (user text or
+   skill-generated), and ~reply-stream~ (for streaming responses).
+   Handles all conditional assembly paths: TIME section, CONFIG section,
+   IDENTITY (assistant name + identity file + standing mandates +
+   reflection feedback), TOOLS, CONTEXT, LOGS. Gracefully degrades when
+   awareness or token-economics skills are not loaded.
+7. (think-call-llm raw-prompt system-prompt reply-stream context): calls
+   the LLM. Checks session budget exhaustion before dispatching
+   (v0.5.0 deferred, ~fboundp~-guarded). Uses streaming
+   (~cascade-stream~) when reply-stream is non-nil and the streaming
+   module is loaded; falls back to ~backend-cascade-call~ otherwise.
+   Returns the raw thought (string or plist with ~:tool-calls~) or
+   a budget-exhaustion message.
+8. (think-parse-response thought): parses the LLM response into an action
+   plist. Handles three paths: structured ~:tool-calls~ (convert JSON args
+   to plist via ~json-alist-to-plist~), raw S-expression text (parse with
+   ~*read-eval* nil~, normalize keywords), and plain text (wrap as
+   ~:MESSAGE~ action). Tracks cost via ~cost-track-backend-call~ when
+   available. Guarantees a valid plist for any input.

+
+** Probabilistic Backend Registry
+
+~*probabilistic-backends*~ is a hash table mapping provider keywords to
+their handler functions. Populated by ~register-probabilistic-backend~.
+Skills like system-model-provider register into this table at boot time.

+  (setf (gethash name *probabilistic-backends*) fn))
+#+end_src
+
+The probabilistic engine maintains three pieces of global state that control how LLM requests are dispatched:
+
+~*provider-cascade*~ is the ordered list of providers to try — if the first one fails, the cascade falls through to the next. ~*model-selector*~ is an optional function that examines the context and picks a model per request (useful for routing simple questions to a small fast model and complex reasoning to a large expensive one). ~*consensus-enabled*~ toggles multi-provider agreement, where multiple LLMs run the same prompt and the system waits for consensus.
+
+Providers register into ~*probabilistic-backends*~ (declared above) via ~register-probabilistic-backend~. The cascade can be changed without restart: (setf *provider-cascade* (quote (:ollama :openrouter))).

+#+end_src
+
+** Cascade Dispatch (backend-cascade-call)
+
+Given a prompt, this function iterates through the provider cascade and calls each backend in order until one succeeds. A provider "succeeds" when it returns ~:status :success~ with content, or when it returns a plain string (the LLM's raw output).
+
+The function has a fallback for every failure mode:
+- If a backend returns ~:status :error~, the cascade moves to the next provider
+- If a backend throws an exception, it is caught and logged, and the cascade moves on
+- If ALL backends are exhausted, a structured LOG message is returned saying "Neural Cascade Failure"
+
+This is deliberately resilient. The system should never crash because an LLM provider is down. It should log the failure, try the next provider, and if all fail, return a diagnostic message that the deterministic engine can present to the user.

+#+end_src
+
+** Think: assemble context and call the LLM
+
+This is the main entry point for the probabilistic engine. Every cognitive cycle goes through here.
+
+The function handles several cases:
+- If a triggered skill provides a probabilistic prompt generator, that replaces the raw user input
+- If the previous proposal was rejected, the rejection trace is injected into the LLM's context so it can self-correct
+- Standing mandates from ~*standing-mandates*~ are injected into the IDENTITY section of the system prompt
+
+The system prompt assembly order — identity (including mandates), tools, context, logs — is intentional: standing mandates appear early in IDENTITY so they set the behavioral frame before the model processes tools, context, and logs.
+
+Token economics (v0.5.0): when ~token-economics~ is loaded, ~think()~ uses
+~context-assemble-cached~ (skips context assembly on heartbeat/delegation),
+~prompt-prefix-cached~ (avoids retransmitting IDENTITY+TOOLS), and
+~enforce-token-budget~ (trims over-budget prompts). Cost is tracked after
+each cascade call via ~cost-track-backend-call~. All four calls are
+~fboundp~-guarded — when the module is not loaded, behavior is unchanged.
+
+~think()~ is the orchestrator that composes three sub-functions:
+
+1. *think-assemble-prompt* — builds the full system prompt from context,
+   awareness, logs, identity, standing mandates, and tool belt.
+2. *think-call-llm* — dispatches to the LLM (streaming or batch cascade).
+3. *think-parse-response* — converts the LLM's output to an action plist,
+   handling structured tool-calls, raw S-expressions, and plain text.
+
+The orchestrator snapshots memory, calls the three phases in sequence,
+and returns the action plist that flows into ~cognitive-verify~.

+
+** Deterministic Engine (cognitive-verify)
+
+The deterministic engine is the strict guard. It receives a proposed action from the probabilistic engine and runs it through every registered deterministic gate, sorted by priority.
+
+**Gate Trace (v0.4.0)**
+
+As part of v0.4.0's TUI differentiator visualizations, ~cognitive-verify~ now accumulates a ~:gate-trace~ — a list of ~(:gate <name> :result <:passed|:blocked|:approval>)~ entries — as each deterministic gate processes the action. The trace is prepended to the result plist via ~list*~ and flows through the pipeline to the TUI actuator, which transmits it to the client.
+
+This is Passepartout's permanent UX advantage: no competitor can ship a gate trace because none has deterministic gates to trace. Claude Code, OpenClaw, and Hermes Agent all use prompt-based guardrails where the safety decision is invisible. In Passepartout, the user sees exactly which nine safety gates ran, what each decided, and why — all at 0 LLM tokens.
+
+Skills register deterministic gates via ~defskill~ with the ~:deterministic~ keyword. Each gate is a function that receives (action context) and returns either:
+- A modified action (the gate approves or adjusts the proposal)
+- A LOG or EVENT plist (the gate rejects the proposal with a reason)
+
+Gates run in priority order, highest first. If any gate returns a LOG or EVENT, the proposal is rejected immediately and the rejection reason flows back to the probabilistic engine via the rejection trace. If all gates pass, the proposal is approved.
+
+This architecture makes safety compositional: each skill adds one constraint. The dispatcher checks secrets. The policy checks explanations. The shell actuator checks destructive commands. No single skill needs to understand the full security model.

+** Reason Gate (Stage 2)
+
+The reason gate is the pipeline stage that orchestrates Think + Determine. It receives a signal, checks if it requires reasoning (only ~:user-input~ and ~:chat-message~ events do), and runs through the cognitive + verification loop.
+
+The loop has retry logic: up to 3 attempts. If the deterministic engine rejects a proposal, the rejection reason is fed back into the next think call so the LLM can self-correct. This loop — propose, reject, correct, re-propose — is the core mechanism by which the agent improves its own output without human intervention.
+
+The retry limit prevents infinite loops. If the LLM cannot produce a passable proposal within 3 attempts, the last rejection reason is attached to the signal and the acted pipeline sees a failed reasoning cycle.

+#+TITLE: The Skill Engine (skills.lisp)
+#+AUTHOR: Agent
+#+FILETAGS: :org:skills:
+#+STARTUP: content
+#+PROPERTY: header-args:lisp :tangle /home/user/.local/share/passepartout/lisp/core-skills.lisp
+
+* Overview: Architectural Intent
+
+The Skill Engine is the dynamic loading and lifecycle manager for all Passepartout skills. It discovers skill files in the skills directory, resolves their dependency order, loads them into jailed packages, and exports their public symbols into the ~passepartout~ package.
+
+** Late-Binding Intelligence
+
+Hardcoding logic into a compiled binary creates a brittle kernel. Every time you add a capability, you must recompile, restart, and re-deploy. Skills solve this by being:
+
+1. **Discovered at boot** — the engine scans a directory for skill files and loads whatever it finds. No registration step needed.
+2. **Dependency-ordered** — skills declare dependencies via ~#+DEPENDS_ON:~ headers. The topological sort ensures they load in the right order.
+3. **Hot-reloadable** — a skill can be replaced at runtime without restarting the daemon. The new version is compiled into a fresh jail package and swapped in.
+4. **Self-documenting** — each skill is a single Org file containing prose, code, metadata, and tests. The "Why" and the "How" are unified.
+
+** The Jailed Package Model
+
+Every skill loads into its own package (e.g., ~PASSEPARTOUT.SKILLS.SECURITY-DISPATCHER~). This prevents name conflicts between skills — two skills can define a function called ~process~ without collision, because each lives in its own namespace.
+
+After loading, the engine exports the skill's public symbols into the ~passepartout~ package, making them available to other skills and the org. The export filter uses the skill's short name as a prefix — for example, the Security Dispatcher exports only symbols starting with ~DISPATCHER-~.
+
+This is how the "thin org, fat skills" principle works in practice: the org provides the loading infrastructure; the skills provide all the intelligence.
+
+** Contract
+
+1. (lisp-syntax-validate code-string): returns T if the Lisp code is
+   structurally valid, nil if reader errors are detected.
+2. (skill-topological-sort dir): reads org files in a directory, parses
+   ~#+DEPENDS_ON:~ declarations, returns files sorted such that
+   dependencies come before dependents.
+
+* Implementation
+
+** Package Context

+
+** Utility functions
+
+Helper functions used by the skill loader and other components.
+
+*** Cosine similarity
+
+Computes the cosine similarity between two numeric vectors. Used by the peripheral vision system for semantic relevance scoring — if the agent's current focus has a vector embedding, objects with similar embeddings get promoted to foveal detail.
+
+#+begin_src lisp
+(defun vector-cosine-similarity (v1 v2)
+  "Computes cosine similarity between two vectors."
+  (let* ((len1 (length v1)) (len2 (length v2)))
+    (if (or (zerop len1) (zerop len2))
+        0.0
+        (let* ((dot 0.0d0) (n1 0.0d0) (n2 0.0d0))
+          (dotimes (i (min len1 len2))
+            (let* ((x (coerce (elt v1 i) 'double-float)) (y (coerce (elt v2 i) 'double-float)))
+              (incf dot (* x y)) (incf n1 (* x x)) (incf n2 (* y y))))
+          (if (or (zerop n1) (zerop n2)) 0.0 (/ dot (sqrt (* n1 n2))))))))
+#+end_src
+
+** Skill data structures
+
+The ~skill~ struct holds all metadata about a loaded skill: its name, priority, dependencies, trigger function, probabilistic prompt generator, and deterministic gate. The ~skill-entry~ struct tracks the loading state of each discovered skill file.
+
+#+begin_src lisp
+(defstruct skill name priority dependencies trigger-fn probabilistic-prompt deterministic-fn)
+#+end_src
+
+#+begin_src lisp
+(defvar *skill-catalog* (make-hash-table :test 'equal)
+  "Tracks all discovered skill files and their loading state.")
+#+end_src
+
+#+begin_src lisp
+(defvar *standing-mandates* nil
+  "List of functions (context) → string-or-nil. Each is called on every think() cycle.
+When non-nil, the returned string is injected into the IDENTITY section of the system prompt.
+Unlike skills (which activate on triggers), standing mandates are always consulted.")
+#+end_src
+
+#+begin_src lisp
+(defstruct skill-entry filename (status :discovered) error-log (load-time 0))
+#+end_src
+
+** Skill discovery (skill-triggered-find)
+
+Iterates the registry and returns the highest-priority skill whose trigger function matches the current context. Only skills with a probabilistic prompt are considered (purely deterministic skills don't need LLM attention).
+
+This is how the system determines which skill "owns" the current user input. For example, if the REPL skill's trigger matches the input, the REPL skill provides the prompt template that shapes how the LLM responds.
+
+#+begin_src lisp
+;; Alias: find-triggered-skill → skill-triggered-find
+(defun find-triggered-skill (context)
+  (skill-triggered-find context))
+
+(defun skill-triggered-find (context)
+  "Returns the highest priority skill whose trigger matches context."
+  (let ((triggered nil))
+    (maphash (lambda (name skill) 
+               (declare (ignore name)) 
+               (when (and (skill-probabilistic-prompt skill)
+                          (ignore-errors (funcall (skill-trigger-fn skill) context)))
+                 (push skill triggered))) 
+               *skill-registry*)
+    (first (sort triggered #'> :key #'skill-priority))))
+#+end_src
+
+** Standing Mandates
+
+Standing mandates are cross-cutting instructions injected into every LLM system prompt. They live in ~*standing-mandates*~, a list of functions ~(context) → string-or-nil~. Each is called on every reasoning cycle; nil results are skipped.
+
+This is the mechanism for always-on behavioral instructions. Skills call their registered trigger function to determine if they should activate for a given context; standing mandates always run and decide themselves whether to contribute text. Use ~push~ to register:
+
+#+begin_example
+(push #'my-mandate *standing-mandates*)
+#+end_example
+
+** Skill registration macro (defskill)
+
+The primary API for skills. Each skill file calls this once to register itself. The macro creates a ~skill~ struct and stores it in ~*skill-registry*~ keyed by the skill's name.
+
+#+begin_src lisp
+(defmacro defskill (name &key priority dependencies trigger probabilistic deterministic)
+  "Registers a new skill. NAME is a keyword. TRIGGER is a function (context) → bool."
+  `(setf (gethash (string-downcase (string ,name)) *skill-registry*)
+         (make-skill :name (string-downcase (string ,name)) 
+                    :priority (or ,priority 10) 
+                    :dependencies ',dependencies
+                    :trigger-fn ,trigger 
+                    :probabilistic-prompt ,probabilistic 
+                    :deterministic-fn ,deterministic)))
+#+end_src
+
+** Dependency resolution (skill-dependencies-resolve)
+
+Recursively resolves all transitive dependencies for a given skill, returning an ordered list. Uses a standard graph traversal with a ~seen~ set to prevent infinite recursion from circular dependencies.
+
+#+begin_src lisp
+(defun skill-dependencies-resolve (skill-name)
+  "Resolves transitive dependencies. Returns list of skill names in dependency order."
+  (let ((resolved nil) (seen nil))
+    (labels ((visit (name)

+                   (when skill 
+                     (dolist (dep (skill-dependencies skill)) (visit dep))))
+                 (push name resolved))))
+      (visit skill-name) 
+      (nreverse resolved))))
+#+end_src
+
+** Skill File Analysis (skill-metadata-parse)
+
+Extracts the ~:ID~ and ~#+DEPENDS_ON:~ declarations from a skill's Org file. Used by the topological sorter to order skills correctly.
+
+#+begin_src lisp
+(defun skill-metadata-parse (filepath)
+  "Extracts ID and DEPENDS_ON tags from org file."
+  (let ((dependencies nil) (id nil) (content (uiop:read-file-string filepath)))

+    (let ((pos 0))
+      (loop while (setf pos (search "#+DEPENDS_ON:" content :start2 pos))
+            do (let ((end (position #\Newline content :start pos)))
+              (when end
+                (let ((line (string-trim " " (subseq content (+ pos 13) end))))
+                  (dolist (d (uiop:split-string line :separator '(#\Space #\Tab)))
+                    (unless (string= d "") (push d dependencies))))
+                (setf pos end)))))
+    (values id (reverse dependencies))))
+#+end_src
+
+** Dependency Resolution (skill-topological-sort)
+
+Returns a list of skill filepaths sorted by dependency order. Uses Kahn's algorithm: collect all files, build an adjacency graph from ~#+DEPENDS_ON:~ declarations, and topologically sort them. Skills with no dependencies are sorted alphabetically.
+
+Both ~.org~ and ~.lisp~ files are included. For each skill, the ~.org~ file supplies the dependency metadata; if a ~.lisp~ file exists, it's loaded instead of tangling from the ~.org~ at load time.
+
+#+begin_src lisp
+(defun skill-topological-sort (skills-dir)

+** Jailed Loading (skill-load-from-org)
+
+The primary skill loader. Given a path to an ~.org~ file:
+
+1. Reads the Org file and collects all ~#+begin_src lisp~ blocks (excluding test blocks and blocks with ~:tangle no~)
+2. Validates the Lisp syntax before loading
+3. Creates a jailed package named after the skill (e.g., ~PASSEPARTOUT.SKILLS.SECURITY-DISPATCHER~) with ~:use :passepartout~
+4. Evaluates the collected Lisp forms in that package
+5. Scans the package for symbols matching the skill's name prefix and exports them to the ~passepartout~ package
+
+The validation step is critical: invalid Lisp in an org block would crash the loader. The validator uses ~read~ with ~*read-eval*~ bound to nil to safely detect syntax errors without evaluating.

+** Sandbox Source Scan (skill-source-scan)
+
+Scans Lisp source text for references to restricted symbols before any

+(~uiop:run-program~, ~uiop:shell~, ~uiop:run-shell-command~), thread

+socket operations (~usocket:socket-connect~, ~hunchentoot:start~).
+
+Returns two values: T/NIL (blocked-p) and a list of matched symbol names.
+The scan is a text-level regex check — it catches direct references but
+not obfuscated ones. The post-eval ~symbol-function~ comparison in

+** Loading from Pre-Tangled Lisp (skill-load-from-lisp)
+
+Loads a pre-tangled ~.lisp~ file directly, without parsing the Org source. This is faster than ~load-skill-from-org~ because it skips the block extraction and syntax validation (the Lisp was already validated when tangled).
+
+The same jailed package and symbol export process applies.
+
+The sandbox check runs *before* evaluation: the source text is scanned for references to restricted symbols (~uiop:run-program~, ~uiop:shell~, ~uiop:run-shell-command~, ~bt:make-thread~, ~usocket:socket-connect~, ~hunchentoot:start~). If the source references any restricted symbol, the skill is blocked immediately without executing any code. A post-eval secondary check catches indirect references (via ~symbol-function~ comparison).

+#+TITLE: Communication Protocol (communication.lisp)
+#+AUTHOR: Agent
+#+FILETAGS: :harness:protocol:
+#+STARTUP: content
+#+PROPERTY: header-args:lisp :tangle /home/user/.local/share/passepartout/lisp/core-transport.lisp
+
+* Overview: Architectural Intent
+
+The Communication Protocol defines how Passepartout speaks to the outside world. It sits between the metabolic loop and the network, providing framed, length-prefixed message transport over TCP.
+
+Every message is an S-expression (plist) prefixed with a 6-character hex length:
+
+  00002C(:TYPE :EVENT :PAYLOAD (:ACTION :handshake :VERSION "0.4.0"))
+
+This is a deliberate rejection of JSON, Protocol Buffers, or any other serialization format. The message format is Lisp-native because:
+
+1. The agent generates and consumes these messages inside the cognitive loop — no serialization layer needed
+2. The format is human-readable and trivially debuggable with a text editor
+3. The length prefix prevents framing attacks (no "read until newline" ambiguity)
+
+** Why Length-Prefixed Framing?
+
+A naive TCP protocol that reads until newline fails when:
+- A message contains a newline character (which Lisp plists can)
+- A message is split across TCP packets (read returns partial data)
+- A malicious client sends an infinite stream without newlines
+
+The length prefix solves all three problems. The reader reads exactly 6 characters (the hex length), then reads exactly that many additional characters. No ambiguous termination, no partial message handling, no newline worries.
+
+The 6-character hex length supports messages up to ~16MB (0xFFFFFF bytes). This is sufficient for any single message the agent would produce. Larger payloads should be split across multiple messages.
+
+** Contract
+
+1. (frame-message msg): serializes a plist message to a length-prefixed
+   string. The first 6 characters are the hex-encoded payload length.
+2. (read-framed-message stream): reads a framed message from a stream,
+   returning the deserialized plist. Consumes exactly the length-prefixed
+   bytes.
+3. Round-trip invariant: ~(read-framed-message (make-string-input-stream
+   (frame-message msg)))~ equals ~msg~.

+
+** Message Framing
+
+Three functions handle the full message lifecycle: sanitize (strip non-serializable state), frame (serialize + prefix), and read (parse from stream).
+
+*** Sanitize Protocol Message
+
+Strips transient runtime state (~:reply-stream~, ~:socket~, ~:stream~) from a message plist before sending it over the network. These are Lisp stream objects that cannot be serialized and have no meaning to the remote end.

+        (nreverse clean))
+      msg))
+#+end_src
+
+*** Frame Message
+
+Serializes a plist to a length-prefixed string: 6-character hex length followed by the ~prin1~ representation.

+#+end_src
+
+*** Read Framed Message
+
+Reads a complete framed message from a TCP stream. Handles leading whitespace between messages, partial reads, and malformed length headers gracefully. Returns the parsed S-expression, or ~:eof~ if the stream is closed, or ~:error~ if the message is malformed.

+
+The TCP server that accepts connections from CLI and TUI clients. Each connection gets a dedicated thread (~client-handle-connection~).

+#+TITLE: Cost Tracker — per-session token cost accounting
+#+AUTHOR: Agent
+#+FILETAGS: :token-economics:cost-tracking:
+#+PROPERTY: header-args:lisp :tangle /home/user/.local/share/passepartout/lisp/cost-tracker.lisp
+
+* Architectural Intent
+
+Cost tracking gives the user visibility into what the agent spends on their
+behalf. No competitor provides this — Claude Code and Copilot obscure cost
+behind flat-rate subscriptions. Passepartout tracks every LLM call, logs
+cumulative cost, and exposes it via a ~/cost~ TUI command.
+
+The tracking is minimal and accurate to within ~10-15% (using the token
+heuristic from tokenizer.lisp). It persists across daemon restarts via
+~*session-cost*~ in the memory store.
+
+** v0.8.0 — Session Summary for Sidebar
+
+The sidebar's Cost panel needs an at-a-glance cost summary: total spent,
+call count, per-provider breakdown. ~cost-session-summary~ packages the
+three existing accessors (~cost-session-total~, ~cost-session-calls~,
+~cost-by-provider~) into a single plist ~(:total <float> :calls <int>
+:by-provider <alist>)~. This is a thin wrapper (~5 lines) — the data
+already exists; the function exposes it in the shape the TUI expects.
+
+Called from ~core-act.org~'s ~:tui~ actuator via ~fboundp~ guard.
+Degrades gracefully to nil when cost-tracker is not loaded.
+
+** Contract
+
+1. (cost-track-call provider prompt-text response-text): compute and
+   accumulate the cost of a single LLM call. Returns the cost in USD.
+2. (cost-session-total): returns the current session's total cost.
+3. (cost-session-reset): zeroes the session cost accumulator.
+4. (cost-format-budget-status total budget): returns a human-readable
+    budget status string for the TUI status bar.
+5. (cost-session-summary): returns plist
+    ~(:total <float> :calls <int> :by-provider <alist>)~ aggregating
+    all three session cost accessors. Consumed by the TUI actuator
+    for the sidebar Cost panel (v0.8.0).
+6. (budget-remaining-usd): returns the remaining budget in USD, or
+   ~most-positive-double-float~ when no budget is set.
+7. (budget-exhausted-p): returns T when a budget is set and fully
+   consumed. ~fboundp~-guarded at call sites so the checker is
+   a no-op when cost-tracker is not loaded.
+8. (budget-estimate-call prompt-text): estimates the dollar cost of a
+   pending LLM call from the prompt text. Returns 0.0 when the
+   tokenizer skill is not loaded (allows the call through).
+9. (budget-exhaustion-message): returns a ~:REQUEST~ plist with a
+   human-readable message explaining the budget cap. Injected as the
+   LLM response when the budget is exhausted.

+- ~:native~ — in-process inference via llama.cpp / CFFI. 768-dim nomic-embed-text-v1.5, zero network calls, <100ms per document on CPU. Requires model file at ~/.local/share/passepartout/models/nomic-embed-text-v1.5.Q4_K_M.gguf and libllama_wrap.so at /usr/local/lib.
+
+The embedding queue (~embed-queue-object~ / ~embed-all-pending~) decouples document indexing from the main loop. On each heartbeat tick, ~embed-all-pending~ drains the queue and embeds all accumulated objects. This prevents indexing traffic from blocking conversational responses.
+
+The default provider is ~:trigram~ — it captures lexical overlap (character trigram bloom filter → cosine similarity approximates Jaccard) and works immediately with zero configuration. Switch to ~:local~ or ~:openai~ when you have an embedding server; switch to ~:sha256~ for integrity-only deployments.
+
+**Why not SHA-256 by default?** SHA-256 is a cryptographic hash with the avalanche property — one-bit input differences produce entirely different outputs. "implement user login form" and "implement user login forn" (one character difference) have completely different SHA-256 values → cosine similarity near zero. This makes SHA-256 correct for integrity verification (Merkle tree) but useless for similarity-based retrieval. The trigram Jaccard approach captures lexical overlap: "authentication" and "authenticate" share trigrams "aut", "uth", "the", "hen", "ent", "nti", "tic", "ica", producing high cosine similarity (0.80). "authentication" and "banana" share zero trigrams → 0.0 similarity.
+
+This replaces the old ~system-embedding-gateway~ with the same logic but renamed to ~system-model-embedding~ to live alongside the other ~system-model-*~ skills.

+* Architectural Intent
+
+=system-model-embedding-native= provides in-process embedding inference via CFFI binding to llama.cpp. Unlike =:local= (Ollama REST API) and =:openai= (paid API), =:native= runs the embedding model directly in the SBCL process — zero network calls, zero external servers.
+
+The bundled model is =nomic-embed-text-v1.5= (nomic-bert, 768-dim, 12 layers, Q4_K_M quantization, ~80MB) at =~/.local/share/passepartout/models/nomic-embed-text-v1.5.Q4_K_M.gguf=. It is a BERT-family encoder-only model — single forward pass, no autoregressive decoding.
+
+**Key architectural decisions**:
+- C wrapper library (=/usr/local/lib/libllama_wrap.so=) bridges CFFI pointer params to llama.cpp's struct-by-value API (CFFI cannot pass/return structs by value)
+- Struct sizes verified via C ~sizeof~ / ~offsetof~: =llama_model_params= (72B), =llama_context_params= (136B), =llama_batch= (56B)
+- Model and context cached globally in =*native-model*= / =*native-context*= to avoid reloading
+- BERT pooling: =llama_get_embeddings_seq= for sequence-level embedding (not =llama_get_embeddings_ith=)
+- =sb-int:set-floating-point-modes= :traps nil required before any llama.cpp call (FPU state conflict)

+
+* Architectural Intent
+
+~system-model-explorer~ answers two questions the config screen needs: "What models does my provider offer?" and "Which one should I use for this task?"
+
+It opens a thin pipe to OpenRouter's /api/v1/models endpoint (no API key needed for the model list), parses the JSON into a uniform set of plists, and caches the result. The TUI's model dropdowns and recommendation cards all read from this cache.
+
+Recommended models are curated per task slot — code generation needs different capabilities than casual chat or background summarization. The recommendations are not hardcoded provider hooks; they're hand-picked from the OpenRouter free tier as a sensible default. Users can override via the TUI config screen, which replaces the picked model IDs into their cascade.
+
+** Contract
+
+1. (model-explorer-recommend slot): returns a list of plists with
+   ~:id~ and ~:name~ for the given task slot (~:code~, ~:chat~,
+   ~:plan~, ~:background~). Unknown slots return a fallback list.
+2. (model-explorer-fetch provider): fetches the model list from the
+   provider's API and caches it. Returns nil on failure.

It speaks the OpenAI-compatible ~/v1/chat/completions~ protocol, which covers every modern provider — OpenRouter, OpenAI, Anthropic, Groq, Gemini, DeepSeek, NVIDIA NIM, plus any local engine (Ollama, vLLM, LM Studio, llama.cpp) when running behind an OpenAI-compatible adapter.
+
+One function, eight (and counting) providers. The same JSON payload, the same response format, the same error handling. Adding a new provider is a one-line config entry: a keyword, a base URL, an API key env var name, and a default model.
+
+Providers register themselves at boot. No API key? That provider doesn't register. No local URL set? The local entry stays dormant. Only the providers you actually configure appear in ~*probabilistic-backends*~ at runtime. The old code assumed Ollama was always available; this code requires an env var like everything else.
+
+=*provider-cascade*= defaults to cloud-only (all providers except ~:local~ and ~:ollama~). If you want a local fallback, set ~LOCAL_BASE_URL~ in your env and add ~:local~ to the ~PROVIDER_CASCADE~ list.
+
+** Contract
+
+1. (provider-config provider): returns the configuration plist for a
+   provider keyword, or nil if unregistered.
+2. (provider-available-p provider): returns T if the provider's API key
+   or base URL is configured.
+3. (provider-openai-request prompt system-prompt &key model provider):
+   executes an OpenAI-compatible /v1/chat/completions request. Returns
+   ~(:status :success :content ...)~ or ~(:status :error :message ...)~.
+4. (provider-openai-request prompt system-prompt &key model provider tools):
+   when ~:tools~ is provided (a list of plist tool definitions), the request
+   body includes ~"tools"~ and ~"tool_choice": "auto"~ fields. Parses
+   ~tool_calls~ from the response: extracts ~function.name~ and
+   ~function.arguments~ (decoded from JSON string to alist). Returns
+   ~(:status :success :tool-calls ((:name <str> :arguments <alist>)))~
+   when the LLM returns a tool call, or the existing ~:content~ path otherwise.
+4. (provider-cascade-initialize): reads ~PROVIDER_CASCADE~ from env and
+   sets ~*provider-cascade*~.
+5. (provider-openai-stream prompt system-prompt callback &key model provider tools):
+   v0.7.1 — executes a streaming OpenAI-compatible /v1/chat/completions
+   request. Sends ~"stream": true~ in the request body. Reads Server-Sent
+   Events (SSE) from the response stream, parsing ~data: ...~ lines. For
+   each delta with content, calls CALLBACK with the delta string. After
+   all deltas, calls CALLBACK with ~""~ to signal end-of-stream. Returns
+   ~(:status :success)~ on completion or ~(:status :error :message ...)~.
+   If ~*stream-cancel*~ is set to T (by another thread), exits the SSE
+   loop and calls CALLBACK with ~""~.
+6. (parse-sse-line line): parses an SSE line. Returns the data content
+   for ~data: <content>~ lines, ~:done~ for ~data: [DONE]~, and ~nil~
+   for comment lines (starting with ~:~), empty lines, or non-data lines.

+
+* Overview: Quadrant-Based Model Routing
+
+The Model Router implements the four-quadrant cognitive architecture for
+LLM model selection. Each signal is routed through a pipeline of three
+filters — privacy, quadrant, and complexity — before a model is chosen.
+
+The routing pipeline for every probabilistic signal:
+
+  all backends → privacy filter → quadrant/classifier → per-slot cascade → model
+
+- **Privacy filter** strips cloud backends when content carries ~@personal~ tags.
+- **Quadrant** determines if the signal is foreground or background.
+- **Complexity classifier** assigns foreground signals to one of three slots:
+  ~:code~, ~:plan~, or ~:chat~.
+- **Per-slot cascade** selects a backend and model for the slot, with fallback
+  ordering defined in each cascade list.
+
+The model selector function is registered into the core ~*model-selector*~ hook
+at load time. The core iterates providers, calling the selector for each one.
+
+* Implementation

+
+** Configuration: Per-Slot Cascades
+
+Four env-configurable cascade variables, one per slot. Each cascade is a list
+of ~(provider-keyword . "model-name")~ pairs. The first match for the current
+backend is used.

-* Overview
-Structural manipulation tools for Lisp code. This skill provides the full toolkit used by the agent when self-editing: ~utils-lisp-validate~ (three-phase structural/syntactic/semantic gate), ~utils-lisp-eval~ (sandboxed evaluation in a jailed package), ~utils-lisp-structural-extract~ / ~inject~ / ~wrap~ / ~slurp~ (surgical code transformations), and ~utils-lisp-format~ (auto-indentation via Emacs batch). Every self-edit operation goes through these functions.
+* Architectural Intent: The Lisp Surgeon's Toolkit
+
+When the agent needs to modify its own code — fix a bug, add a feature, refactor a skill — it reaches for Utils Lisp. This skill provides every operation needed to read, validate, modify, and write Lisp code from within Lisp itself.
+
+This is possible only because Lisp is homoiconic: code is data. The agent can parse a function definition from a string, extract its body, wrap it in a new form, inject a new expression, and validate the result — all using the same data structures that the Lisp runtime uses to execute the code.
+
+The skill has four layers:
+1. **Validation** — three-phase gate: structural (paren balance) → syntactic (reader safety) → semantic (dangerous forms)
+2. **Evaluation** — sandboxed ~eval~ in a jailed package with ~*read-eval*~ nil
+3. **Structural surgery** — extract, inject, wrap, slurp — surgical code transformations without regex
+4. **Formatting** — auto-indentation via Emacs batch mode
+
+** Contract
+
+1. (lisp-structural-check code): returns (values T nil) if parentheses
+   balanced, (values nil error-msg) if reader errors detected.
+2. (lisp-syntactic-check code): alias for lisp-structural-check.
+3. (lisp-semantic-check code): returns (values T nil) if no unsafe forms
+   (eval, load, run-program) found; (values nil reason) if blocked.
+4. (lisp-validate code &key strict): unified gate — returns
+   ~(:status :success)~ or ~(:status :error :reason ...)~.
+5. (lisp-eval code-string): sandboxed eval with captured output.
+   Returns ~(:status :success :result ...)~ or ~(:status :error ...)~.
+6. (lisp-extract code fn-name): extracts a single defun from code.
+7. (lisp-list-definitions code): returns list of defined symbol names.
+8. (lisp-inject code target new-form): injects a form into a function body.
+9. (lisp-slurp code target form): appends a form to a function body.

+
+* Overview
+This skill enforces the literal programming discipline for all Passepartout source code. It defines the rules for one-function-per-block, prose-before-code, reflecting working code back from the REPL to Org, and the tangle mandate (never edit .lisp directly). Every Org file that contains Lisp code should follow the rules defined here.
+
+** Contract
+
+1. (literate-extract-lisp-blocks content): extracts concatenated
+   Lisp code from all ~#+begin_src lisp~ blocks in an Org string.
+2. (literate-block-balance-check org-file): checks that parentheses are
+   balanced across all lisp blocks in an Org file. Returns T or nil.
+3. (literate-tangle-sync-check org-file lisp-file): verifies the
+   tangled .lisp file matches the Org source. Returns T or mismatch info.

+* Overview
+Structural manipulation tools for Org-mode files. This skill handles reading, writing, and modifying Org files at the AST level: finding headlines by ID or title, setting properties and TODO states, adding new headlines, generating UUIDs, and converting ASTs back to Org text. It also implements the privacy filter — when reading an Org file, it strips headlines tagged with ~@personal~ (or any tag in the Dispatcher's privacy tags) and rejects files with matching ~#+FILETAGS:~.
+
+** Contract
+
+1. (org-id-generate): returns a new UUID string.
+2. (org-id-format id): ensures the ID has an "id:" prefix.
+3. (org-property-set ast target-id property value): recursively sets a
+   property on a headline matching target-id. Returns T on success.
+4. (org-todo-set ast target-id status): sets TODO status via
+   org-property-set.
+5. (org-headline-add ast parent-id title): adds a new child headline.
+6. (org-headline-find-by-id ast id): returns the subtree for a matching
+   headline ID.
+7. (org-id-get-create ast target-id): ensures a headline has an :ID: property.
+   If the headline already has one, returns it. If not, generates a new UUID,
+   sets it, and returns it. Returns nil if the headline is not found.

 * Overview
 The *REPL Skill* provides persistent Lisp evaluation, inspection, and debugging capabilities. This enables the agent to verify behavior at runtime rather than just at the text level.

+1. (repl-eval code-string &key package): evaluates Lisp code in a
+   sandboxed environment (~*read-eval* nil~). Returns (values result
+   output error) as three strings. Adds to ~*repl-history*~.
+2. (repl-inspect symbol-name &key package): returns a formatted string

+3. (repl-list-vars &key package): returns a list of bound variable

+
+* Overview
+The *Engineering Standards Skill* defines the REPL-first engineering lifecycle and enforces technical invariants, including the **Commit-Before-Modify** rule and **Chaos-Driven Development**.
+
+** Architectural Intent + Testable Contract
+
+Every Org module must open with an ~* Architectural Intent~ section.
+This section is the machine-readable specification that tests are written
+against. A test that does not verify a stated intent is testing trivia.
+An intent without a test is aspirational.
+
+*** Template
+
+Place this before ~* Implementation~ in every Org file:
+
+#+begin_src org
+,* Architectural Intent
+
+[Prose: why this module exists, what problem it solves.]
+
+,** Contract
+
+The functions in this module guarantee the following:
+
+1. (function-name): accepts X, returns Y. Preserves invariant Z.
+2. (function-name): when given A, guarantees B (error, signal, or result).
+3. ...
+
+,** Boundaries
+
+What this module explicitly does NOT do, and where that responsibility
+lives instead.
+#+end_src
+
+The ~* Test Suite~ section at the bottom of the file lists each test
+with a cross-reference to which contract item it verifies:
+
+#+begin_src org
+,* Test Suite
+
+,** test-rejection (verifies Contract item 3)
+,** test-pass-through (verifies Contract item 1)
+#+end_src
+
+*** Example: ~symbolic-diagnostics.org~
+
+#+begin_src org
+,* Architectural Intent
+
+The Diagnostics skill is the self-knowledge of Passepartout. It answers
+"Is everything working?" by probing external dependencies at startup.
+
+,** Contract
+
+1. (diagnostics-dependencies-check): probes PATH for every binary in
+   *diagnostics-binaries*. Returns T if all found, NIL if any is
+   missing. Side-effect: populates *doctor-missing-deps*.
+2. (diagnostics-env-check): validates XDG directories exist. Returns T
+   if all critical dirs present, NIL otherwise.
+3. (diagnostics-run-all): orchestrates 1-3. Returns a plist with
+   :deps, :env, :llm keys. Respects :auto-install nil.
+
+,** Boundaries
+
+- Does NOT fix missing dependencies — that is diagnostics-dependencies-install.
+- Does NOT start or stop LLM services — that is the provider layer.
+#+end_src
+
+*** Rules
+
+1. Every ~.org~ file with ≥1 ~defun~ MUST have an ~* Architectural Intent~ section.
+2. The ~** Contract~ section MUST list every public function.
+3. Every test in ~* Test Suite~ MUST reference a specific Contract item.
+4. If you change a function's signature, you MUST update its Contract item.
+
+** Contract
+
+The standards skill itself guarantees:
+
+1. (standards-git-clean-p dir): checks whether directory ~dir~ has
+   uncommitted git changes. Returns T if clean, NIL if dirty. Runs
+   ~git status --porcelain~ in the target directory.
+2. (standards-lisp-verify code): validates Lisp code string for
+   structural correctness. Delegates to ~lisp-syntax-validate~.
+3. (standards-lisp-format code): applies formatting conventions to
+   Lisp code. Delegates to ~lisp-format~.

+
+* Cognitive Tools for Codebase Operations
+
+This skill registers ten cognitive tools that let the LLM search codebases, read and write files, evaluate Lisp expressions, run tests, and manipulate Org files. Without these tools, the agent can chat and run shell commands but cannot perform the core operations of a programming assistant.
+
+Each tool is registered via ~def-cognitive-tool~ and appears in the LLM's tool belt prompt via ~cognitive-tool-prompt~. Tools receive arguments as a plist and return a plist with ~:status~ (~:success or :error~) and either ~:content~ (success) or ~:message~ (error). The tool executor (~action-tool-execute~) normalizes nested argument lists, dispatches by name, and feeds results back into the perception pipeline.
+
+** Contract
+
+1. Every tool returns a plist with at least ~:status~. On success: ~(:status :success :content "...")~. On error: ~(:status :error :message "...")~.
+2. Every tool guards against missing required parameters and returns a clear error message.
+3. Every tool handles runtime exceptions (~handler-case~) — a tool must never crash the daemon.
+4. ~search-files~: given ~:pattern~, ~:path~, optional ~:include~ (glob), returns matched lines with file:line prefixes.
+5. ~find-files~: given ~:pattern~ (glob), ~:path~, returns list of matching file paths.
+6. ~read-file~: given ~:filepath~, optional ~:start~, ~:limit~ (lines), returns file contents.
+7. ~write-file~: given ~:filepath~, ~:content~, creates directories, writes file, returns byte count.
+8. ~list-directory~: given ~:path~, optional ~:pattern~, returns sorted directory entries.
+9. ~run-shell~: given ~:cmd~, optional ~:timeout~, returns stdout, stderr, and exit code.
+10. ~eval-form~: given ~:code~ (Lisp expression string), returns evaluated result. Disables ~*read-eval*~.
+11. ~run-tests~: given optional ~:test-name~, runs specific test or all suites via ~fiveam:run-all-tests~.
+12. ~org-find-headline~: given ~:id~ or ~:title~, searches ~*memory-store*~ for matching memory objects.
+13. ~org-modify-file~: given ~:filepath~, ~:old-text~, ~:new-text~, performs exact-string replacement. Returns error if text not found.
+14. (tool-register-modified filepath &key old-content new-content):
+    appends a modification record to ~*modified-files-this-turn*~.
+    Returns the record plist ~(:filepath <s> :timestamp <unix>
+    :lines-added <n> :lines-removed <n>)~.
+15. (tool-modified-files-summary): returns the list of modified-file
+    plists accumulated this turn and clears ~*modified-files-this-turn*~.
+    Returns nil when no files were modified.
+
+** v0.8.0 — Modified Files Tracking
+
+The sidebar's Files panel needs to know which files the agent modified in
+the most recent tool execution. ~*modified-files-this-turn*~ is a list of
+plists tracking each write operation: ~(:filepath <string> :timestamp <unix>
+:lines-added <int> :lines-removed <int>)~.
+
+~tool-register-modified~ is called by ~write-file~ and ~org-modify-file~
+after successful writes. It computes line counts by comparing the old and
+new content (when available) or records the operation with nil counts.
+~tool-modified-files-summary~ returns the accumulated list and resets
+it for the next turn (reset happens at the start of each ~think()~ cycle
+in ~core-reason.lisp~).
+
+The tracking is per-turn, not cumulative — the sidebar shows what changed
+in the /last/ tool execution, matching the tool-execution visualization
+pattern from v0.7.1. Cumulative file tracking belongs in the version
+control system.

+* Overview: The Authorization Matrix
+
+Every cognitive tool (file read, file write, shell execute, etc.) has a permission level: ~:allow~ (executed without asking), ~:ask~ (user is prompted before execution), or ~:deny~ (blocked entirely). Tool Permissions maintains the registry of these levels and provides the ~permission-gate-check~ that the Dispatcher calls before dispatching a tool action.
+
+The complexity lives in the Dispatcher (security-dispatcher.org), which
+consults this table as one of its ten scan vectors.
+
+** Contract
+
+1. (permission-set tool-name level): stores ~level~ for ~tool-name~
+   in ~*permission-table*~. Tool names are normalized to lowercase.
+2. (permission-get tool-name): returns the stored level, or ~:ask~ if
+   no entry exists.
+3. Tool name matching is case-insensitive — ~(permission-set :FOO :allow)~
+   and ~(permission-get :foo)~ return ~:allow~.
+
+** Boundaries
+
+- Does NOT enforce permissions — the Dispatcher does that.
+- Does NOT persist permissions to disk — this is runtime-only.
+- Does NOT validate that ~level~ is one of ~(:allow :ask :deny)~.

+
+* Architectural Intent: The Constitutional Layer
+
+The Policy skill encodes the non-negotiable values of Passepartout. Every action the agent proposes must pass through this gate. If the action lacks justification, it is blocked — not because it's dangerous, but because it's opaque.
+
+This is the "Radical Transparency" invariant in practice. The agent must explain *why* it wants to do something, not just *what* it wants to do. An action with ~:explanation "Because I said so"~ is rejected. An action with ~:explanation "The user asked me to read their TODO list and summarize it"~ passes.
+
+The Policy skill is intentionally simple. It has one job: ensure every action has a meaningful explanation. Other security concerns (secret scanning, path blocking, network exfiltration) are handled by the Dispatcher. The Policy is about values, not threats.
+
+** Contract
+
+1. (policy-compliance-check action context): if ~action~ has an
+   ~:explanation~ string longer than 10 characters, returns the action
+   unchanged. Otherwise, returns a ~:LOG~ rejection plist with
+   ~:level :warn~.

+* Overview
+The Protocol Validator enforces schema compliance on every message entering or leaving the cognitive pipeline. It checks that messages are valid plists, that they have the required ~:type~ and ~:payload~ fields, and that the type is one of the known types (~:REQUEST~, ~:EVENT~, ~:RESPONSE~, ~:LOG~, ~:STATUS~).

+
+The Protocol Validator wraps ~validate-communication-protocol-schema~

+The *Credentials Vault* provides secure in-memory storage for sensitive API keys and session tokens.

+
+The Credentials Vault isolates secrets from the rest of the system in

+through here.
+
+** Contract
+
+1. (vault-set provider secret &key type): stores secret under
+   ~(format nil "~a-~a" provider type)~ in ~*vault-memory*~.
+2. (vault-get provider &key type): returns the stored secret, or falls
+   back to the appropriate environment variable for known providers
+   (~:openai~, ~:anthropic~, ~:openrouter~, ~:gemini~). Returns NIL
+   if neither exists.
+3. (vault-get-secret provider): wrapper — calls ~vault-get~ with
+   ~:type :secret~.
+4. (vault-set-secret provider secret): wrapper — calls ~vault-set~
+   with ~:type :secret~.
+5. Vault isolation: storing a secret for provider A does not affect
+   provider B's entry. Different ~:type~ values produce different keys.
+
+** Boundaries
+
+- Does NOT encrypt at rest — that is the session layer's responsibility.
+- Does NOT validate key format — the provider skill does that.
+- Does NOT rotate or expire keys — this is a simple store.

+
+* Architectural Intent
+
+The heartbeat fires every 60 seconds for maintenance. It can also carry temporal
+awareness — scanning for approaching deadlines, tracking session duration, and
+injecting temporal context so the LLM knows the current time without triggering
+a call.
+
+This skill provides:
+1. ~format-time-for-llm~ — injectable TIME section for system prompt
+2. ~session-duration~ — session start tracking
+3. ~sensor-time-tick~ — deadline scanning registered as cron job
+
+All pure Lisp, 0 LLM tokens for temporal awareness.
+
+** Contract
+
+1. (format-time-for-llm &key session-duration): returns a human-readable TIME
+   section string. Respects ~TIME_AWARENESS~ and ~TIME_FORMAT~ env vars.
+2. (session-duration): returns seconds since skill load, or nil.
+3. (sensor-time-tick): scans memory for headlines with ~:DEADLINE~ or
+   ~:SCHEDULED~ properties. If any are within ~DEADLINE_WARNING_MINUTES~,
+   returns a formatted deadline note string. Returns nil otherwise.

-The *Kernel Bootstrap* provides the absolute minimum logic required to transition from a raw POSIX shell to a functional Lisp environment.
+* Overview: Architectural Intent
+
+The Kernel Bootstrap is the transition from a bare POSIX shell to a running Lisp environment. It's the only part of Passepartout that executes before the Lisp image is ready.
+
+The bootstrap has exactly three jobs, nothing more:
+1. **Directory Resolution**: Locating and creating XDG paths for config, data, and state
+2. **System Tangle**: Transforming literate Org sources into runnable Lisp files
+3. **Dependency Check**: Ensuring SBCL, Quicklisp, and Emacs are available
+
+This minimal interface is deliberate. The bootstrap should NOT know about LLM providers, diagnostic suites, or gateway configuration. Those are the job of the Lisp-level setup wizard, which runs after the bootstrap is complete.

+
+* Overview
+
+The *Archivist* combines the former Scribe and Gardener skills into a unified
+maintenance subsystem. It runs as a background skill triggered by heartbeat
+events, performing two core functions:
+
+- Scribe: Distills daily chronological logs into structured atomic notes with
+  backlinks, maintaining the Zettelkasten knowledge base.
+- Gardener: Scans the Memex for structural issues — broken =[[file:...]]= links
+  and orphaned =memory-object= entries — flagging them for human review.
+
+** Contract
+
+1. (archivist-extract-headlines content): parses Org content into a
+   list of headline structures, each with ~:title~, ~:body~, ~:tags~.
+2. (archivist-headline-to-filename title): sanitizes a headline title
+   into a valid filename — lowercased, special chars replaced.
+3. (archivist-create-note headline notes-dir source): writes a
+   Zettelkasten note to disk with frontmatter and backlinks.
+4. (archivist-scribe-distill): heartbeat-driven — reads recent log
+   entries from ~*history-store*~ and creates structured notes.
+5. (archivist-gardener-scan): heartbeat-driven — scans for broken
+   file links and orphaned memory objects.

+
+* Overview: Architectural Intent
+
+The Context API implements the Foveal-Peripheral awareness model. When the agent thinks, it doesn't dump everything it knows into the LLM's context window — that would saturate the token budget immediately. Instead, it builds a skeletal outline of the entire Memex and only shows full detail for the current focus.
+
+This mirrors human attention: you are aware of your entire apartment (peripheral vision), but you only see the book in front of you in detail (foveal vision).
+
+** The Foveal-Peripheral Model
+
+Three factors determine how much detail an object gets:
+
+1. **Depth** — objects within 2 levels of the root get full outline (title + ID). Deeper objects are summarized or omitted.
+2. **Foveal focus** — the object the user is currently interacting with gets full content rendered.
+3. **Semantic similarity** — objects whose vector embedding is similar to the current foveal focus get promoted from peripheral to foveal detail.
+
+** Why Not Just Dump Everything?
+
+A naive implementation that serializes every ~org-object~ to text would produce hundreds of thousands of tokens for a typical knowledge base. The LLM would spend its attention budget on noise, not signal. The Foveal-Peripheral model preserves the signal (the current task and related information) while reducing noise (everything else).
+
+The semantic threshold is configurable via ~CONTEXT_SEMANTIC_THRESHOLD~ env var (default 0.75). Lower values include more peripherally related content; higher values restrict to tightly related content.
+
+** Semantic Retrieval Activation (v0.4.0)
+
+In v0.3.0, the infrastructure for semantic retrieval was in place — the cosine similarity calculation, the semantic threshold check, and the embedding pipeline — but ~:foveal-vector~ was never passed to ~context-object-render~. It was always ~nil~, so ~(if (and foveal-vector obj-vector ...) ...)~ always took the ~0.0~ branch. Every peripheral node had similarity zero regardless of content overlap.
+
+The fix is a one-line wiring: ~context-awareness-assemble~ now extracts the foveal node's embedding vector via ~(memory-object-vector (memory-object-get foveal-id))~ and passes it as the ~:foveal-vector~ keyword argument to ~context-object-render~. This activates the entire semantic retrieval path — nodes with high cosine similarity to the foveal node are promoted to full-content rendering.
+
+The effectiveness of this depends on the embedding backend. The default ~:trigram~ backend (v0.4.0 replacement for ~:hashing~/SHA-256) captures lexical overlap: if two nodes share enough character trigrams, their cosine similarity exceeds the threshold and the peripheral node is promoted to foveal detail. This gives the context model genuine semantic boosting with zero LLM tokens and zero external dependencies.
+
+** Contract
+
+1. (context-awareness-assemble &optional signal): produces a skeletal
+   outline of current Memory for the LLM. If ~:foveal-focus~ is set,
+   the foveal node gets inline rendering; peripheral nodes get title-only.
+   Privacy-filtered objects are excluded.
+2. (context-assemble-global-awareness): zero-arg wrapper — calls
+   ~context-awareness-assemble~ without foveal focus.

-* Overview
-The *Diagnostics Skill* (Doctor) provides system-wide health checks and dependency verification. It validates external dependencies, XDG environment, and LLM provider connectivity.
+* Why a Doctor?
+
+The Diagnostics skill is the self-knowledge of Passepartout. It answers "Is everything working?" by checking dependencies, environment variables, and LLM connectivity. Unlike the harness-level Doctor (which runs at boot and on CLI demand), this skill provides the Lisp-level diagnostic functions — defining what "healthy" means: which binaries must be present, which directories must exist, which API keys should be configured.
 
 * Phase A: Demand (Thinking)
 ** Why a Doctor?
@@ -13,43 +14,66 @@ The Doctor transforms opaque startup failures into actionable engineering report
 ** Detection Invariant
 Binary detection must use shell probing (`which`) to account for varying `$PATH` inheritance between interactive and headless sessions.
 
-* Phase B: Protocol (Success Criteria)
-- Dependency check passes when all required binaries are found
-- Environment check passes when XDG directories exist and are accessible
-- LLM check passes when at least one provider is configured or Ollama is running locally
+* Phase B: Contract
+
+1. (diagnostics-dependencies-check): probes PATH for every binary in
+   ~*diagnostics-binaries*~. Returns T if all found, NIL if any missing.
+   Side-effect: populates ~*doctor-missing-deps*~.
+2. (diagnostics-env-check): validates XDG directories exist. Returns T
+   if all critical dirs present, NIL otherwise.
+3. (diagnostics-run-all &key auto-install): orchestrates 1-3. Returns
+   a plist with ~:deps~, ~:env~, ~:llm~ keys. Respects ~:auto-install nil~.

+#+TITLE: SKILL: Event Orchestrator (symbolic-events.org)
+#+AUTHOR: Agent
+#+FILETAGS: :system:orchestrator:hooks:cron:
+#+PROPERTY: header-args:lisp :tangle /home/user/.local/share/passepartout/lisp/symbolic-events.lisp
+
+* Architectural Intent
+
+The Event Orchestrator unifies three control-plane mechanisms that were previously scattered across the system:
+
+1. **Hooks** — actions triggered when Org nodes with specific ~#+HOOK:~ properties are modified
+2. **Cron** — time-based scheduled jobs using Org-mode timestamp repeat expressions
+3. **Routing** — three-tier complexity classifier that decides whether a job needs the LLM at all
+
+Before the Orchestrator, each of these was handled ad-hoc. The heartbeat thread injected raw ~:heartbeat~ signals that skills had to parse themselves. Memory auto-save was a hardcoded counter in ~core-loop~. There was no way to say "when this file changes, verify its integrity" or "archive old tasks every Sunday."
+
+The Orchestrator attaches to the heartbeat as a deterministic gate (same pattern as the Dispatcher, the Archivist, and every other heartbeat-driven skill). On each tick, it checks the cron registry for due jobs and dispatches them at the appropriate tier.
+
+** The three tiers:
+
+| Tier | LLM? | Mechanism | Example |
+|------|------|-----------|---------|
+| ~:reflex~ | No | Direct function call | "Run integrity check" |
+| ~:cognition~ | Light | Injected as user-input | "Summarize today's notes" |
+| ~:reasoning~ | Full | Injected as user-input | "Plan the project architecture" |
+
+The default classifier uses keywords in the context to determine the tier: ~rm~, ~write-file~, ~shell~ → ~:reflex~; ~summarize~, ~list~, ~find~ → ~:cognition~; everything else → ~:reasoning~. This can be overridden by setting ~*tier-classifier*~ to a custom function.

+
+** Registries
+
+The hook registry maps Org-mode property names (like ~verify-integrity~ from a ~#+HOOK: verify-integrity~ headline property) to lists of gate function symbols. When a node with that hook is modified, the orchestrator calls each gate in sequence.
+
+The cron registry maps job names (keywords like ~:weekly-report~) to configuration plists. Each entry contains the repeat expression, the action function, and the dispatch tier.

+2. `(agent-identity)`:
+   Returns the cached identity string (`*agent-identity*`), or `""` if

+
+* Overview
+Because Lisp is homoiconic (code is data), memory objects can be read as executable forms. This skill provides the bridge between the org-object store and live Lisp evaluation — it can serialize an org-object into an s-expression, evaluate it to reconstruct state, and store the result back as a new object. This is the foundation of the agent's ability to save, restore, and inspect its own cognitive state at runtime.

+#+FILETAGS: :system:context:scoping:
+#+PROPERTY: header-args:lisp :tangle /home/user/.local/share/passepartout/lisp/symbolic-scope.lisp
+
+* Overview
+
+The Context Manager provides stack-based project focusing. When the agent
+"focuses" on a project, file paths resolve relative to it and memory queries
+auto-filter by scope. This enables the agent to work within a bounded context
+without being distracted by unrelated memory.
+
+The core provides the mechanism (=memory-object-scope=, =context-query= with
+scope parameter). This skill provides the policy — what to focus on, what
+scope means for each project, and how the stack is managed.
+
+** Contract
+
+1. (push-context &key project base-path scope): pushes a context plist
+   onto ~*context-stack*~. Blocks if depth exceeds ~*context-max-depth*~.
+2. (pop-context): pops and returns the top context. If the stack would
+   become empty, inserts a default memex-wide context instead.
+3. (current-context): returns the top-of-stack context plist.
+4. (current-scope): returns the ~:scope~ keyword from the current context.
+5. (current-project): returns the ~:project~ name from the current context.
+6. (current-base-path): returns the ~:base-path~ from the current context.
+7. (context-stack-depth): returns the number of contexts on the stack.
+8. (focus-project name base-path): pushes a new context for the named
+   project. Sets ~*scope-resolver*~ to return ~:project~.
+9. (focus-session): pushes an ephemeral context for the current session.
+10. (focus-memex): pushes a global memex-wide context.
+11. (unfocus): pops one level from the context stack.
+12. (resolve-path path): resolves a path relative to the current base-path.
+13. (context-scoped-query &key tag todo-state type): queries memory filtered
+    by the current context's scope.
+14. (context-save): persists the context stack to disk.
+15. (context-load): restores the context stack from disk on startup.

+
+* Overview: Self-Modification Primitives
+
+Self-Improve combines the former Self-Edit and Self-Fix skills into a unified
+self-modification subsystem. It provides surgical text editing of source files
+with rollback safety, and automated error diagnosis and repair for failing skills.
+
+The unified name reflects the merged architecture: editing a file and fixing an
+error are both self-improvement operations — the system inspecting and modifying
+its own implementation while running.
+
+* Implementation
+
+** Infrastructure: Org Tangle Utility
+
+Reads an Org file's ~#+PROPERTY: header-args:lisp :tangle~ line, extracts
+all ~#+begin_src lisp~ blocks, writes them to the target ~.lisp~ file, and
+compiles+loads the result. Used by the self-improve functions to propagate
+edits and repairs to the running daemon.

+
+* Architectural Intent
+
+Every ~memory-object~ carries a ~version~ timestamp (~get-universal-time~) set on
+ingest since v0.1.0. But ~context-query~ in ~symbolic-awareness~ has no time
+filter — "what did I work on today?" serializes all nodes to the LLM instead
+of filtering 500→12 in sub-millisecond Lisp.
+
+This skill adds temporal query primitives and extends ~context-query~ with
+~:since~ / ~:until~ keyword parameters. Pure Lisp, sub-millisecond, 0 LLM
+tokens. ~90% token reduction on time-scoped memory queries.
+
+** Contract
+
+1. (memory-objects-since timestamp): walks ~*memory-store*~ returning objects
+   with ~version >= timestamp~.
+2. (memory-objects-in-range since until): returns objects with version between

+#+TITLE: SKILL: System Integration Tests
+#+AUTHOR: Agent
+#+PROPERTY: header-args:lisp :tangle /home/user/.local/share/passepartout/lisp/system-integration-tests.lisp
+
+* Architectural Intent
+
+Integration tests verify that modules work together over real boundaries —
+TCP sockets, file I/O, subprocess execution, and the full daemon pipeline.
+Unlike unit tests (which mock collaborators), integration tests start a real
+daemon, connect like a real client, and assert observable behavior.
+
+** Contract
+
+Phase 1 — In-process daemon (no external credentials):
+
+1. (start-daemon &key port): binds port, sends handshake on connect.
+2. Pipeline: a ~:user-input~ event traverses the full pipeline.
+3. Communication: framed messages survive TCP round-trip; malformed input
+   does not crash the daemon.
+4. Skill loader: after daemon start, ~*skill-registry*~ is populated.
+5. Shell actuator: safe commands execute; dangerous patterns are blocked.
+6. CLI gateway: text injected via TCP reaches the pipeline.
+7. Gateway registry: ~gateway-registry-initialize~ is available.
+
+Phase 2 — LLM + messaging:
+
+  8. Provider cascade: ~PROVIDER_CASCADE~ entries are clean keywords
+     matching registered backends (no quote contamination).
+  9. Backend cascade: real provider returns string content.
+
+Phase 3 — TUI via tmux (rendering diagnostics):
+
+  10. Cascade inspection: ~/eval *provider-cascade*~ shows clean keywords
+      on TUI screen (no quote artifacts from cl-dotenv).
+  11. Eval command: ~/eval (+ 1 2)~ displays ~~=> 3~~ on screen.
+  12. Status bar: rendered screen shows ~~msgs:~~ in status bar.
+  13. Direct render: ~/eval (add-msg :agent ...)~ renders text on screen
+      independent of daemon — isolates TUI rendering from pipeline.
+  14. Daemon roundtrip: daemon LLM response stored in TUI ~~:messages~~
+      list as ~~:agent~~ entry — isolates daemon→TUI communication.
+  15. Full render: agent response text appears on rendered screen
+      after LLM roundtrip — tests complete TUI→daemon→LLM→TUI pipeline.
+
+** Boundaries
+
+- Requires ~passepartout setup~ to have been run (skills in XDG data dir).
+- Phase 2 tests skip if required env vars are unset.
+- Phase 3 tests require tmux and Emacs installed.
+
+* Prologue
+
+Shared test harness: package, suite, helpers, and ~with-daemon~.

+#+TITLE: Token Economics — caching, budget, and cost wiring
+#+AUTHOR: Agent
+#+FILETAGS: :token-economics:budget:caching:
+#+PROPERTY: header-args:lisp :tangle /home/user/.local/share/passepartout/lisp/token-economics.lisp
+
+* Architectural Intent
+
+Token economics transforms the architecture's theoretical cost advantage into
+operational reality. Three subsystems work together:
+
+1. ~Prompt prefix caching~ — the IDENTITY+TOOLS portion of the system prompt
+   is static across calls (changes only on skill load or identity config).
+   Hashing and caching it avoids retransmitting ~500-1500 tokens per call.
+
+2. ~Incremental context assembly~ — the CONTEXT section is only regenerated
+   when the foveal focus, scope, or memory state changes. Heartbeat ticks
+   and tool-output feedback produce no context change, so assembly is skipped,
+   saving ~200-800 tokens per heartbeat.
+
+3. ~Token budget enforcement~ — when the total prompt exceeds
+   ~CONTEXT_MAX_TOKENS~ (default 16384), the system progressively trims
+   less-essential sections (logs first, then standing mandates, then
+   peripheral context).
+
+These functions are called from ~think()~ via ~fboundp~ guards, keeping
+core-reason thin while enabling token economics as a hot-loadable skill.
+
+Depends on: tokenizer.lisp, cost-tracker.lisp
+
+** v0.8.0 — Context Usage for Sidebar
+
+The sidebar's Context gauge needs a single integer: 0-100 representing
+how much of the token budget is consumed. ~context-usage-percentage~
+computes this from ~*context-cache*~'s stored token counts and
+~CONTEXT_MAX_TOKENS~ (or the model's context limit from ~tokenizer~).
+
+The function is a thin wrapper (~8 lines): read the most recent context
+assembly's token count from ~*context-cache*~, divide by the budget,
+multiply by 100, clamp to [0, 100]. Called from ~core-act.org~'s ~:tui~
+actuator via ~fboundp~ guard. Degrades gracefully to nil when
+token-economics is not loaded.
+
+** Contract
+
+1. (prompt-prefix-cached assistant-name identity-content feedback mandates-text tool-belt):
+   Build the IDENTITY+TOOLS system prompt prefix. Uses ~sxhash~ on the inputs
+   to detect changes. Returns the cached string when unchanged.
+2. (context-assemble-cached context sensor): Incrementally assemble awareness
+   context. Skips assembly entirely for ~:heartbeat~ / ~:delegation~ sensors.
+   Returns cached context when foveal-id, scope, and memory timestamp are
+   unchanged. Falls back to ~[Awareness skill not loaded]~ when
+   ~context-assemble-global-awareness~ is not ~fboundp~.
+3. (enforce-token-budget prefix ctxt logs user prompt mandates &optional max):
+   Enforce per-call token budget via progressive trimming:
+   L1: truncate logs to last 5 lines
+   L2: drop standing mandates
+   L3: downgrade context to single-line summary
+   Returns (values trimmed-prefix trimmed-ctxt trimmed-logs trimmed-user trimmed-mandates).
+4. (token-economics-initialize): zeroes the cache state at daemon boot.
+5. (context-usage-percentage): returns integer 0-100 representing
+    current token budget consumption from ~*context-cache*~. Clamped.
+    Returns nil when no context cache data is available. Consumed by
+    the TUI actuator for the sidebar Context gauge (v0.8.0).
