Move config/test/models to daemon TCP protocol, TUI uses .env fallback

- Daemon: add handle-client-config inline handler for :config-get,
  :config-set, :config-list, :provider-test, :provider-models
- TUI cmd-config: write .env directly, send reload to daemon if connected
- TUI: /config test and /config models send TCP to daemon (fallback:
  daemon-not-running message)
- Add Test Provider and Discover Models to Ctrl+P daemon commands

+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.
 
-**One-line install:**
+*Install:*
 
 #+begin_src bash
-curl -fsSL https://raw.githubusercontent.com/amrgharbeia/opencortex/main/passepartout | bash -s configure
+curl -fsSL https://raw.githubusercontent.com/amrgharbeia/passepartout/main/passepartout | bash -s configure
 #+end_src
 
-Then ~passepartout 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.
+
+* What is an AI Agent?
+
+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.
+
+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.
+
+* What Makes Passepartout Different
+
+** Every action is verified, not trusted.
+
+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.
+
+Every gate costs 0 LLM tokens. Every gate is a Common Lisp function, not a prompt. Every gate runs for every action, unconditionally.
+
+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.
+
+** The more you use it, the cheaper it gets (architectural aspiration)
+
+Passepartout is designed with a downward cost curve — an architectural property, not yet measured empirically. Here is the thesis.
+
+When you use Passepartout, the Dispatcher observes every blocked action and every human-approved exception. Each decision becomes a deterministic rule. A file write you approved once becomes an allowed path pattern. A shell command you denied becomes a permanent block. Each hardened rule means one fewer LLM call next time. This rule-learning system is planned for v0.5.0.
+
+Meanwhile, the foveal-peripheral context model prunes your [[https://en.wikipedia.org/wiki/Memex][memex]] — your personal knowledge base, a term coined by Vannevar Bush in 1945 for a mechanised private library — to the relevant Org subtrees before sending anything to the LLM. The agent does not load your entire knowledge base, or even the entire file like agents that use Markdown do — it loads precisely the headlines that matter. Less context in, fewer tokens out.
+
+These mechanisms are implemented and working today. Token cost measurement and optimization are tracked in the [[file:docs/ROADMAP.org][v0.5.0 Roadmap]]. Until empirically verified, the cost claims in [[file:docs/DESIGN_DECISIONS.org][Design Decisions]] (2-3x fewer tokens for coding, 13-24x for knowledge management) should be read as architectural projections, not measured results.
+
+** It edits its own source code. Verified before execution.
+
+Passepartout can read its own Org-mode source files, propose changes, and hot-reload skills into the running image without restarting. The skill engine loads every skill into a jailed Common Lisp package, validates its syntax, tests its trigger function in isolation, and only then promotes it to the live registry.
+
+Core pipeline files — the Perceive-Reason-Act loop, the Merkle-tree memory, the Dispatcher gate stack — are path-protected. The agent could modify its own brain stem, but it cannot do this without human review. Skills and system modules expand freely. The core stays small, protected, and auditable.
+
+No other AI agent can modify its own reasoning engine and reload the change while it is running. This is not a planned feature. It works today.
+
+** Your memory and your tasks are the same format. Org-mode.
+
+Passepartout makes a bet that most systems consider too expensive: humans and machines should share the same file format. That format is Org-mode.
+
+Your notes, your calendar, your project plans, the agent's memory, and the agent's own source code are all the same thing: Org files in ~/memex/. =headline trees. Property drawers for metadata. Source blocks for code. TODO keywords for task state. Tags for categorization.
+
+When you write a TODO in Emacs, the agent sees it immediately as a native data structure and acts on it. When the agent creates a note, you can open it in any text editor and read it. There is no import/export step, no hidden database (except maybe for indexing), no format conversion. If Passepartout stops existing tomorrow, your data survives in plain text, readable in 2040.
+
+** Works offline. Works locally. The safety doesn't stop.
+
+You can run Passepartout entirely on your hardware with a local LLM via Ollama or some other inference engine. No internet connection required. But unlike most local AI tools, offline mode does not mean safety-last. The ten deterministic safety gates are pure Common Lisp — they run identically whether you are online or off. The Merkle-tree memory with snapshot rollback is in-process, 0 milliseconds, 0 network calls. Semantic retrieval runs on in-image vectors, 0 LLM tokens per query.
+
+Cloud providers (OpenRouter, OpenAI, Anthropic, Groq, Gemini, DeepSeek, NVIDIA NIM...) are optional add-ons. When you use them, the model-tier router automatically selects the cheapest provider that matches your task's complexity. Privacy-tagged content stays local even when cloud providers are configured.
+
+* How It Works
+
+Every signal — a chat message, a heartbeat tick, a file change notification — moves through three stages:
+
+#+begin_example
+Signal  →  Perceive  →  Reason  →  Act
+            normalize    LLM proposes  dispatch approved action
+                         gates verify  tool output feeds back

+
+*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.

-* Why Passepartout
-
-** Your data stays yours.** No database, no vector store, no cloud silo. Your entire memory is a folder of Org files. You can read them with any text editor, search them with grep, and back them up however you like. If Passepartout stops existing, your data doesn't disappear.
-
-** The LLM can't do damage.** Every action the LLM proposes passes through a deterministic safety gate before it touches a file, runs a command, or sends a message. The LLM suggests; the gate decides. Hallucinations are blocked, not corrected after the fact.
-
-** Runs on your hardware.** Works fully offline with Ollama and local models. Cloud providers (OpenRouter, OpenAI, Anthropic, Groq, Gemini, DeepSeek, NVIDIA NIM) are optional add-ons.
-
-** Written in Common Lisp.** Code is data. The agent reads its own source the same way it reads a text file — it parses, modifies, and hot-reloads its skills without restarting. One language from the kernel to the TUI to the build system.

 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                                           |

+| 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.

+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.

-#+TITLE: Changelog
-#+STARTUP: content
-
-* v0.2.1 — Rename, Safety, and Deployment (2026-05-02)
-This release renames the project to Passepartout, adds content-level safety gates, professionalizes deployment, and documents every function with full explanatory prose.
-
-** Project Rename
-- **Passepartout:** Project renamed from OpenCortex to Passepartout. All files, packages, functions, and environment variables updated.
-- **Org/lisp split:** Source of truth lives in ~org/~, tangled to ~lisp/~. Core files committed, skills generated at configure time.
-- **31 org files:** Every file renamed to ~category-subject.org~ convention. Harness and skills unified under one directory.
-
-** Safety
-- **Secret Exposure Gate:** Content scanning for API keys, PEM blocks, PGP keys, credentials, and tokens in all outgoing text.
-- **Path Protection:** File reads blocked for ~.env~, SSH keys, PEM/PGP, cloud configs, and credential stores.
-- **Shell Safety:** Destructive commands (~rm -rf /~, ~dd~, ~mkfs~, ~shred~) and injection patterns (backtick, ~$()~) blocked with timeout and output limits.
-- **Lisp Validation Gate:** Writes to ~.lisp~ and ~.org~ files validated for syntax errors before they reach disk.
-- **REPL Verification Lint:** Warns if defuns are written without REPL prototyping.
-
-** Deployment
-- **Multi-distro:** Automatic detection of Debian vs Fedora, correct package names and managers.
-- **systemd service:** User-level auto-start on boot via ~passepartout install service~.
-- **Backup/Restore:** ~passepartout backup~ and ~passepartout restore~ commands.
-- **Docker:** Updated to ~debian:trixie-slim~, fixed build context.
-- **CI/CD:** GitHub Actions workflows for lint, test, and release. Gitea deploy workflow fixed.
-
-** Engineering Process
-- **REPL-first Lifecycle:** Two-track workflow: Org-first for prose and tests, REPL-first for implementation. Every function prototyped in the REPL before reaching Org.
-- **Verification Loop:** Bouncer rejects bad lisp; rejection trace feeds back to LLM for self-correction.
-- **System-prompt-augment:** Skills can inject domain-specific mandates into the LLM prompt via ~:system-prompt-augment~.
-
-** Documentation
-- **Literate Prose Restored:** Every Org file now has an Architectural Intent overview and explanatory prose before each function block, following the style established in the v0.1.0 era.
-- **AGENTS.md:** Thinned to a routing layer — the skill org files are authoritative.
-
-** Contributors
-- **gitignore:** ~skills/*.lisp~ and ~tests/*.lisp~ as generated artifacts (source of truth is ~.org~).
-- **DeepSeek and NVIDIA NIM:** Added as LLM providers (OpenAI-compatible). Use ~DEEPSEEK_API_KEY~ and ~NVIDIA_API_KEY~ env vars.
-
-* v0.2.0 - Interactive Refinement (2026-04-29)
-This release focuses on professionalizing the environment and enhancing the agent's structural capabilities.
-
-** Features
-- **Enhanced Lisp/Org Utilities:** Structural editing, REPL evaluation, and automated formatting to ensure code integrity.
-- **Namespace Standardization:** Refactored utilities into =utils-org= and =utils-lisp= for predictable discovery.
-- **Autonomous Mandates:** Implemented =GEMINI.md= for local agentic enforcement of engineering standards.
-- **Onboarding Wizard:** Modular Lisp setup for multiple LLM providers.
-- **Professional TUI:** Styled, scrollable interface with improved diagnostics.
-
-* v0.1.0 - The Autonomous Foundation (2026-04-20)
-This is the initial MVP release of the ~passepartout~. It establishes a secure, auditable Lisp kernel for a personal operating system.
-
-** Features
-- **Unified Envelope Architecture:** Actuator-agnostic protocol that decouples routing metadata from cognitive payloads, ensuring all clients (TUI, Emacs, CLI, Matrix) are treated as equal citizens.
-- **Metabolic Pipeline:** Robust Perceive-Reason-Act loop with selective memory rollbacks and graceful shutdown handling.
-- **Verification Lock:** Mandatory skill enforcement via environment configuration. System halts if security policies or bouncers fail to load.
-- **Foveal-Peripheral Context:** High-resolution focus on active tasks with low-resolution skeletal awareness of the rest of the Memex.
-- **The Bouncer:** Last-mile deterministic security gate with Deep Packet Inspection for secrets and network exfiltration.
-- **Autonomous Scribe:** Background distillation worker that turns daily journal entries into evergreen Zettelkasten notes. Verified to distill atomic concepts autonomously.
-- **Autonomous Gardener:** Heartbeat-driven worker that repairs broken links and identifies orphaned nodes in the Memex graph.
-- **Unified Onboarding:** Single-command installation (~passepartout.sh~) with Docker support, OS detection, and automated dependency resolution.
-- **Channel-Aware TUI:** Interactive Croatoan-based terminal client with clean, human-readable formatting for tool results and system logs.
-- **CLI Gateway:** Local TCP socket server for pipe-friendly interaction and frictionless first contact.
-
-** Licensing & Community
-- **AGPLv3 License:** Passepartout is now officially licensed under the GNU Affero General Public License v3.0.
-- **Contributor License Agreement:** Implemented a broad CLA (~CLA.org~) for long-term project sustainability.
-
-** Architectural Shift
-- Transitioned to **Literate Granularity**: Every function and invariant is now formally documented in its own Org block.
-- **Provider Agnosticism:** Implemented a dynamic LLM cascade (OpenRouter, Ollama, etc.) removing all hardcoded backend dependencies.
-- **Thin Harness Philosophy:** Decoupled the kernel from specific editors or third-party gateways.

 * Philosophy
 Passepartout is built on a "Zero-Bloat" mandate. The core kernel is mathematically pure, pushing all peripheral logic, API integrations, and routing to hot-reloadable "Skills".
 
-* Literate Granularity
+* Development Workflow
-We strictly adhere to Literate Programming using Org-mode.
+
-- *Never* edit `.lisp` files in `src/` directly.
+The full development cycle is described in ~AGENTS.md~. In summary:
-- Modify the corresponding `.org` files in the `literate/` or `skills/` directories.
+
-- Run `org-babel-tangle` to generate the source code.
+1. *Think in org* — write reasoning and goals in the .org file
-- Every architectural decision, constraint, and implementation detail must be documented alongside the code in the `.org` file.
+2. *Write contract* — define each function's behavior in a ~** Contract~ section
+3. *TDD from contract* — each contract item becomes a ~fiveam:test~; prove RED then GREEN
+4. *Reflect in org* — ensure implementation is in .org source
+5. *Update literate prose* — explain the code: what, why, how it connects
+
+* Literate Programming
+
+~.org~ files in ~org/~ are the source of truth. ~lisp/~ files are generated by ~org-babel-tangle~.
+
+- Never edit =lisp/= files directly — always modify the corresponding =org/= file
+- All ~#+begin_src lisp~ blocks in a file inherit their tangle destination from the file-level ~#+PROPERTY: header-args:lisp :tangle ../lisp/FILE.lisp~
+- Every architectural decision, constraint, and implementation detail must be documented alongside the code
+
+* Contracts and Tests
+
+Every code change starts with a contract and a failing test. Write a ~** Contract~ section listing each function's behavior, then create a ~fiveam:test~ in the ~* Test Suite~ section for each contract item.
+
+To run tests for a specific file:
+
+#+begin_src bash
+sbcl --noinform \
+  --eval '(load (merge-pathnames "quicklisp/setup.lisp" (user-homedir-pathname)))' \
+  --eval '(ql:quickload :passepartout :silent t)' \
+  --eval '(load "lisp/FILE.lisp")' \
+  --eval '(fiveam:run (intern "SUITE-NAME" :passepartout-TESTS))' --quit
+#+end_src
+
+No test may be committed without proof it was first run to failure (RED).
 
 * Skill Creation Standard
-Skills are the building blocks of Passepartout. They reside in the `skills/` directory.
 
-A skill must define:
+A skill is a =.org= file in =org/= that defines:
-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).
 
-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)
+* Project Structure
-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.

+
+** 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
 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 ~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
+
+| Combo     | Action                                    |
+|-----------+-------------------------------------------|
+| ~Ctrl+D~  | Quit the TUI                              |

+| ~Down Arrow~     | Next input in command history                    |
+
+** The Status Bar
+
+The status bar at the bottom of the TUI shows the agent's current state at a glance. Each indicator has a specific meaning:
+
+| Indicator        | Meaning                                                            |
+|------------------+--------------------------------------------------------------------|
+| ~[Connected]~    | Green — daemon is reachable on port 9105. Gray — disconnected.     |
+| ~[Mode: TUI]~    | The current interaction mode (TUI, CLI, Telegram, etc.)            |
+| ~[Msg: 142]~     | Total messages in the current session                              |
+| ~[↑ 12]~         | Scroll indicator — you are scrolled up 12 lines from the bottom    |

-#+AUTHOR: 
-#+STARTUP: content
-#+FILETAGS: :docs:plan:remediation:
-
-* Summary
-
-Features marked DONE in the ROADMAP for v0.1.0 and v0.2.0 but whose implementations
-are stubs, no-ops, or missing critical functionality. These should have been
-completed in their respective versions and must be addressed before v0.3.0
-development proceeds.
-
-* P0: system-archivist — Proper Distillation and Link Maintenance
-
-** Claimed status**: =DONE= (v0.1.0: "Scribe + Gardener background workers" + v0.2.0: "31 org files with full literate prose")
-
-** Actual state**: =archivist-log= is a trivial log wrapper (~10 lines). No knowledge
-distillation, no broken link detection, no orphaned node flagging.
-
-** What it should do**:
-
-*** Scribe (knowledge distillation)
-1. Read daily Org log files from the Memex =daily/= directory
-2. Identify new entries (since last processed commit or timestamp)
-3. Extract conceptual claims, decisions, and atomic facts from prose
-4. Generate atomic Zettelkasten notes in =notes/= with:
-   - Descriptive snake_case filename (no dates)
-   - =:CREATED:= property from the source log's date
-   - =Source:= backlink to the original daily file and headline
-   - Tags inferred from content and parent file
-5. Track processed state to avoid re-distilling the same content
-
-*** Gardener (structural maintenance)
-1. Scan all Org files in the Memex for broken =[[file:...][...]]= links
-2. Scan =memory-store= for =memory-object= entries whose =:parent-id= or =:children=
-   references point to deleted objects (orphaned nodes)
-3. Flag broken links and orphans with =:GARDENER: broken-link= or =:GARDENER: orphan= tags
-4. Generate a maintenance report as a Org buffer the user can review
-
-*** Implementation approach
-- Wire into =system-event-orchestrator= as cron jobs:
-  - Scribe: daily cron (="<%%Y-%%m-%%d %%a +1d>"=, tier =:cognition=)
-  - Gardener: weekly cron (="<%%Y-%%m-%%d %%a +1w>"=, tier =:cognition=)
-- Use =orchestrator-register-cron= to schedule
-- Replace the trivial =archivist-log= function with real implementation
-- Track last-processed state via =memory-store= (:LATEST_PROCESSED_DATETIME property)
-  or git commit hash
-
-** Dependencies**: =system-event-orchestrator= (cron scheduling), =core-memory= (object store)
-
-** Verification**: FiveAM test that creates a daily log with known content, runs the
-Scribe, and asserts that an atomic note was created with correct backlinks.
-
-* P0: system-self-improve — Surgical Self-Editing and Self-Repair
-
-** Claimed status**: =DONE= (v0.2.0: "Self-editing (error detection, surgical fix, hot-reload)")
-
-** Actual state**: =self-improve-edit= does =(declare (ignore old-text new-text))= followed by
-a log message — no actual text transformation. =self-improve-fix= same pattern.
-The skill's trigger is =nil= so it never fires.
-
-** What it should do**:
-
-*** Self-edit (surgical text replacement)
-1. Accept (=filepath=, =old-text=, =new-text=) and apply the transformation
-2. Read the file, locate =old-text= (with exact match verification), replace with =new-text=
-3. If the target is an Org file with a =#+begin_src lisp= block, tangling the file
-   and reloading the skill after edit
-4. Create a memory snapshot before editing (rollback safety)
-5. Verify the edit succeeded (re-read file, confirm =new-text= appears)
-6. Return success/failure with a diff summary
-
-*** Self-fix (error diagnosis and repair)
-1. Accept (=skill-name=, =error-log=) and diagnose the failure
-2. Parse the error log for: syntax errors (unmatched parens, invalid forms),
-   undefined symbol references, semantic issues (prohibited forms)
-3. For syntax errors: locate the problematic region, propose a correction
-   using structural Lisp knowledge
-4. For undefined references: check if the symbol exists in another package,
-   if the skill's =#+DEPENDS_ON:= declaration is missing a dependency
-5. For semantic issues: identify the prohibited operation and suggest alternatives
-6. Invoke =self-improve-edit= to apply the fix
-7. After repair, run the skill's tests if they exist; if tests pass, hot-reload
-
-*** Implementation approach
-- Add an actual =:trigger= function that activates on =:ERROR= or =:STUCK= signal types
-- =self-improve-edit=: use =uiop:read-file-string=, string replacement with
-  =ppcre:regex-replace= or substring operations, write back with =with-open-file=
-- =self-improve-fix=: add structural analysis in =programming-lisp.lisp= for error parsing
-- Leverage the REPL skill for verification after repair (call =lisp-eval= on the fixed code block)
-
-** Dependencies**: =programming-lisp= (lisp-structural-check), =programming-org= (tangling),
-=core-memory= (snapshot-memory), =core-skills= (jailed reload)
-
-** Verification**: FiveAM test that creates a file with known content, calls self-improve-edit,
-and asserts the replacement was applied. Second test with a file containing a
-deliberate error, calls self-improve-fix, and asserts the error was corrected.
-
-* P1: system-event-orchestrator — Bootstrap Implementation
-
-** Claimed status**: v0.3.0 partially DONE ("hook-registry + cron-registry + tier classifier")
-
-** Actual state**: Hook/cron registries, tier dispatching, and heartbeat integration work.
-But =orchestrator-bootstrap= is a stub: =(log-message "ORCHESTRATOR: Bootstrap complete")=
-
-** What it should do**:
-
-1. Scan the Memex =projects/= and =notes/= directories for Org files containing =#+HOOK:= properties
-2. For each =#+HOOK:= property found, call =orchestrator-register-hook= with
-   the hook name and a gate function
-3. For files with =#+CRON:= properties (or cron expressions in timestamps),
-   register them via =orchestrator-register-cron=
-4. Log the count of registered hooks and cron jobs at completion
-5. Run bootstrap once at startup (after memory is loaded but before cognitive loop begins)
-
-*** Implementation approach
-- Use =uiop:directory-files= with glob patterns for =*.org= files
-- Use =org-element= from Emacs (via =emacs-bridge= or =org-eval= skill) for parsing,
-  or implement a simple regex-based Org property parser in Lisp
-- Walk each file's headlines, extract property drawers, filter for =HOOK:= and =CRON:= keys
-- Call existing =orchestrator-register-hook= / =orchestrator-register-cron=
-
-** Dependencies**: =programming-org= (Org file parsing), file system access
-
-** Verification**: Create a test Org file with =#+HOOK: on-write=, run bootstrap,
-assert the hook registry contains the expected entry.
-
-* P1: system-memory — Memory Introspection
-
-** Claimed status**: Skill exists but was never part of a version milestone.
-
-** Actual state**: =memory-inspect= is a no-op: =(log-message "MEMORY: Self-inspection triggered.")=
-The =:trigger= is =nil= so the skill never activates.
-
-** What it should do**:
-
-1. Return a structured report of memory state:
-   - Total objects in =*memory-store*=
-   - Distribution by type (=:HEADLINE=, =:PARAGRAPH=, etc.)
-   - Distribution by =:TODO-STATE= (=TODO=, =NEXT=, =DONE=, etc.)
-   - Count of privacy-filtered objects
-   - Most recent objects (by =:version= timestamp)
-   - Current snapshot count and timestamps
-   - Orphaned objects (parent-id references a deleted ID)
-2. Accept an optional filter to narrow the report (by type, by tag, by time range)
-3. Wire the trigger to activate on =:INTROSPECTION= signal type or =/memory= commands
-
-*** Implementation approach
-- Iterate =*memory-store*= with =maphash=, collect statistics
-- Add to skill trigger: =(eq (getf (getf ctx :payload) :sensor) :introspection)=
-- Return results as a plist that can be rendered in the TUI
-
-** Dependencies**: =core-memory= (memory-store and memory-object struct)
-
-** Verification**: Ingest known objects, call memory-inspect, assert type counts and
-object counts match.
-
-* P2: core-context — Semantic Retrieval (Embeddings)
-
-** Claimed status**: The foveal-peripheral model is implemented and tested, but the
-embedding pipeline that feeds it is listed as TODO for v0.3.0.
-
-** Actual state**: The context rendering code (=context-object-render=) computes
-=cosine-similarity= correctly, but =org-object-vector= is never populated.
-All objects have =nil= vectors, all similarities are =0.0=, and the model
-falls back to "include everything within depth 2." This is functionally
-equivalent to no retrieval at all.
-
-** What it should do**:
-
-1. Add a =populate-vector= function to =core-memory= that calls an embedding
-   provider and stores the result in the =memory-object= =:vector= slot
-2. At ingest time (=ingest-ast=), generate embeddings for new objects
-3. Embedding provider options (in priority order):
-   - Ollama (local, =nomic-embed-text= or =mxbai-embed-large=)
-   - OpenAI-compatible embedding API (=text-embedding-3-small=)
-   - Fallback: TF-IDF bag-of-words vector (no external dependency)
-4. Updates: when =memory-object= content changes, mark =:vector= as =:pending=
-   and process in a background batch via the event orchestrator
-5. Add an environment variable =EMBEDDING_PROVIDER= with default =ollama=
-
-*** Implementation approach
-- Add an =:embedding-provider= function stored in =*config*=
-- =embed-object=: take content string → call provider → store float vector
-- Modify =ingest-ast= to call =embed-object= on each new object
-- Add batch processing in =system-event-orchestrator= for vector updates
-- Use =bordeaux-threads= with a lock for async embedding generation
-
-** Dependencies**: External embedding provider (Ollama or API), =core-memory= (vector slot)
-
-** Verification**: Create objects with content, run embedding pipeline, assert vectors
-are non-nil and have the correct dimensionality. Verify that =cosine-similarity=
-between semantically similar objects exceeds 0.75 threshold.
-
-* P2: core-context — Subtree-Based Skill Source Loading
-
-** Claimed status**: DESIGN_DECISIONS §"Org-Mode as Unified AST" describes: "When the
-agent needs information about the =openctl-db= function, it queries for the
-=openctl-db= subtree specifically."
-
-** Actual state**: =context-skill-source= reads the ENTIRE Org file as a string via
-=uiop:read-file-string=. No subtree query exists.
-
-** What it should do**:
-
-1. Add a =context-skill-subtree= function that takes (=skill-name=, =heading-name=)
-   and returns only the content under that headline
-2. Add a =context-skill-function-signature= function that returns only the function
-   name, lambda list, and docstring
-3. Add a =context-skill-tests= function that returns only test blocks
-4. Modify =context-skill-source= to optionally accept a =:subtree= keyword argument
-5. If the Org file has an Org-element parser available, use it for structural queries;
-   otherwise fall back to regex-based headline matching
-
-*** Implementation approach
-- Use =org-element= via =org-eval= skill (REPL bridge to Emacs) if available
-- Lisp-native fallback: parse Org headlines with regex (=^*+ = pattern),
-   match heading name by string comparison, extract content until next
-   headline of equal or higher level
-- Cache parsed results to avoid re-parsing on repeated queries
-
-** Dependencies**: =programming-org= (Org parsing utilities), =emacs-bridge= (if Emacs
-Org-element is preferred)
-
-** Verification**: Create a test Org file with multiple headlines, query for a specific
-subtree, assert only that subtree's content is returned.
-
-* Priority and Sequencing
-
-The remediation should proceed in this order:
-
-1. **system-event-orchestrator bootstrap** (P1) — needed as infrastructure for Scribe/Gardener cron scheduling
-2. **system-archivist** (P0) — depends on orchestrator for cron scheduling
-3. **system-self-improve** (P0) — independent, can proceed in parallel with #2
-4. **core-context embeddings** (P2) — independent, unlocks semantic retrieval
-5. **core-context subtree loading** (P2) — independent, improves context efficiency
-6. **system-memory inspect** (P1) — lowest priority, nice-to-have introspection
-
-P0 items must be completed before v0.3.0 development begins. P1 items should be
-completed before v0.3.0 is released. P2 items can extend into early v0.3.0.
-
-* Out of Scope
-
-Features listed as TODO in the ROADMAP for v0.3.0+ are NOT in this remediation
-plan. Specifically excluded:
-
-- HITL continuation-based suspension (v0.3.0 TODO)

+;;; passepartout.el --- Emacs bridge for Passepartout AI assistant  -*- lexical-binding: t; -*-
+
+;; 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
+;;   M-x passepartout-disconnect  — close connection

+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.

+
+* 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.

+#+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.

+#+TITLE: Stage 3: Act (act.lisp)
+#+AUTHOR: Agent
+#+FILETAGS: :harness:act:
+#+STARTUP: content
+#+PROPERTY: header-args:lisp :tangle /home/user/.local/share/passepartout/lisp/core-act.lisp
+
+* 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.
+
+* Implementation
+
+** Package Context
+#+begin_src lisp
+(in-package :passepartout)
+#+end_src
+
+** 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.

-#+TITLE: Stage 3: Act (act.lisp)
-#+AUTHOR: Agent
-#+FILETAGS: :harness:act:
-#+STARTUP: content
-#+PROPERTY: header-args:lisp :tangle ../lisp/core-loop-act.lisp
-
-* 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 Bouncer, 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 ~deterministic-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.
-

-** Package Context
-#+begin_src lisp
-(in-package :passepartout)
-#+end_src
-
-** 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.

-** 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.

-** System Actuator (action-system-execute)

-#+end_src
-
-** Tool Actuator (action-tool-execute)
-
-Executes a registered cognitive tool. Cognitive tools are registered via ~def-cognitive-tool~ in the package.lisp and are the primary way the LLM interacts with the outside world.
-
-The function handles:
-- Tool dispatch by name (case-insensitive lookup)
-- Argument normalization (if the arguments are nested in a list, they're flattened)
-- Result formatting (structured results are sent back to the source)
-- Error handling (tool errors produce ~:tool-error~ events, not crashes)
-
-The tool's return value is packed into a ~:tool-output~ event and fed back into the pipeline, where it becomes the next perception. This is how the agent "sees" the result of its actions.

-#+end_src
-
-** Act Gate (Stage 3)
-
-The final stage of the metabolic pipeline. It receives a signal that has been reasoned (has an ~:approved-action~) and dispatches it.
-
-The gate runs a last-mile deterministic check on the approved action before execution. This catches any issues introduced during pipeline processing (e.g., metadata added by Perceive that changes the action's format).
-
-After dispatch, the gate captures any feedback produced by the actuation (tool output, error events) and returns it to the loop for the next cognitive cycle.

-
-* 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.
-
-* Implementation
-
-** Package Context
-#+begin_src lisp
-(in-package :passepartout)
-#+end_src
-
-** Probabilistic Engine State
-
-The probabilistic engine maintains four pieces of global state that control how LLM requests are dispatched:
-
-~*backend-registry*~ is a hash table mapping provider keywords (like ~:ollama~ or ~:openrouter~) to the actual function that calls that provider's API. ~*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.
-
-These variables are configurable at runtime. The cascade can be changed without restart: (setf *provider-cascade* (quote (:ollama :openrouter))).

-
-#+begin_src lisp
-(defvar *consensus-enabled* nil)
-#+end_src
-
-** Backend Registration (backend-register)
-
-Each LLM provider registers itself by calling this function. The backend function receives a prompt string, a system prompt string, and optional keyword arguments for model selection. It must return either a plist with ~:status :success~ and ~:content~, or ~:status :error~ with a message.
-
-Registration is typically done at boot time by the unified-llm-backend skill, but can also be done dynamically:
-  (backend-register :my-custom-provider #'my-fn)
-

-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.

-** Cognitive Proposal Generation (think)
-
-The ~think~ function is where the creative brain does its work. It assembles the full context for the LLM: the system identity, the available tools, the current global context from memory, the recent system logs, and any rejection trace from a previous failed proposal. It also collects augment strings from any skill that has registered a ~system-prompt-augment~ function.
-
-A note on the augment system: skills can contribute context-specific mandates to the LLM prompt. For example, the REPL skill injects the "prototype in the REPL first" mandate when the context suggests the agent is editing Lisp code. This keeps domain-specific instructions out of the harness while still ensuring they appear in the prompt when relevant.
-
-The LLM's response is expected to be a plist. If it is, it gets parsed and normalized. If it's a string that starts with ~(~ or ~[~, it's read as Lisp data. If it's neither, it falls back to a REQUEST with a MESSAGE action — the raw text.
-
-** Pre-processing: strip markdown from LLM output
-
-LLMs often wrap structured output in markdown code fences:
-
-  ```lisp
-  (:TYPE :REQUEST ...)
-  ```
-
-This function strips the fences so the reader can parse the plist.
-
-#+begin_src lisp
-(defun markdown-strip (text)
-  (if (and text (stringp text))
-      (let ((cleaned text))
-        (setf cleaned (cl-ppcre:regex-replace-all "^```[a-z]*\\n" cleaned ""))
-        (setf cleaned (cl-ppcre:regex-replace-all "\\n```$" cleaned ""))
-        (setf cleaned (cl-ppcre:regex-replace-all "```" cleaned ""))
-        (string-trim '(#\Space #\Newline #\Tab) cleaned))
-      text))
-#+end_src
-
-** Normalize plist keywords
-
-Lisp keywords are case-sensitive. The LLM might produce ~:payload~ or ~:PAYLOAD~ or ~:Payload~ depending on the model. This function normalizes all keyword keys to uppercase to ensure the deterministic engine receives consistent input.
-
-#+begin_src lisp
-(defun plist-keywords-normalize (plist)
-  (when (listp plist)
-    (loop for (k v) on plist by #'cddr
-          collect (if (and (symbolp k) (not (keywordp k)))
-                       (intern (string k) :keyword)
-                       k)
-          collect v)))
-#+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
-- Skills can augment the system prompt with domain-specific mandates via the ~system-prompt-augment~ mechanism
-
-The system prompt assembly order — identity, tools, context, logs, mandates — is intentional: the most dynamic content (mandates from skills) comes last so it has the most influence on the LLM's output.

-** 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.
-
-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 bouncer 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.

 ** 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.

+** 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.

 ** 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.

+
+* 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~.

+#+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.

+
+** 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.

-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 BOUNCER skill exports only symbols starting with ~BOUNCER-~.

+** Sandbox Source Scan (skill-source-scan)

 ** 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: 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.

+* Architectural Intent
+
+~system-model-embedding~ converts text into vector representations for semantic search and memory retrieval. It provides three backends:
+
+- ~:trigram~ — a zero-dependency fallback that uses character-trigram Jaccard similarity. Pure Lisp, works fully offline, captures lexical overlap.
+- ~:sha256~ — integrity-only (explicit opt-in). SHA-256 hashing for environments where even trivial computation is undesirable.
+- ~:local~ — any OpenAI-compatible ~/api/embeddings~ endpoint (Ollama, vLLM, etc.)
+- ~:openai~ — the OpenAI ~/v1/embeddings~ API with an API key
+- ~: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.

+#+AUTHOR: Agent
+#+FILETAGS: :skill:system:embedding:cffi:
+#+PROPERTY: header-args:lisp :tangle /home/user/.local/share/passepartout/lisp/embedding-native.lisp
+
+* 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)

-* Overview
-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.

-
-* Architectural Intent
-
-The Gateway Manager is the unified interface for all external messaging platforms. It handles Telegram, Signal, and any future gateway through a common pattern: a registry of poll/send function pairs, a configuration hash table for tokens and intervals, and a background thread per gateway that polls for new messages.
-
-Each gateway follows the same lifecycle:
-1. **Register** — the gateway's poll and send functions are registered in ~*gateway-registry*~
-2. **Link** — the user provides a token; it's stored in the vault and a polling thread is started
-3. **Poll** — the thread calls the poll function on an interval, injecting received messages into the pipeline
-4. **Unlink** — the thread is destroyed, the config is removed
-5. **Act** — when the agent needs to send a message, it dispatches to the gateway's send function via the generic actuator mechanism
-
-* Implementation
-
-** Platform state — configs
-Storage for active gateway connections: tokens, polling threads, and intervals.

-#+PROPERTY: header-args:lisp :tangle ../lisp/gateway-provider.lisp
-
-* Architectural Intent
-
-The Unified LLM Backend provides a single OpenAI-compatible API client that works with any provider supporting the ~/v1/chat/completions~ endpoint. This covers local engines (Ollama, vLLM, LM Studio, llama.cpp) and cloud providers (OpenRouter, OpenAI, Anthropic, Groq, Gemini, DeepSeek, NVIDIA NIM).
-
-The key design decision: **one client, many configurations**. Instead of having separate skills for each provider (org-skill-ollama, org-skill-openai, etc.), this single skill holds a configuration table mapping provider keywords to their base URL, API key env var, and default model. The same ~provider-openai-request~ function works for all of them.
-
-Providers are registered automatically at boot based on which API keys are set in the environment. If OPENAI_API_KEY is set, OpenAI is available. If not, it's skipped silently.
-
-Providers are registered automatically based on available environment variables.
-No separate skills per provider — just different base URLs and API keys.

-** Provider registry (~*provider-configs*~)

-#+TITLE: Passepartout TUI Client (Standalone)
-#+STARTUP: content
-#+FILETAGS: :tui:ux:client:
-#+PROPERTY: header-args:lisp :tangle ../lisp/gateway-tui.lisp
-
-* Overview: Architectural Intent
-
-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 at the top and a fixed input line at the bottom.
-
-Unlike the CLI gateway (which is a single request-response cycle), the TUI is a persistent connection. It maintains a background reader thread that listens for incoming messages from the daemon and enqueues them for display. This allows the agent to send messages to the user asynchronously — tool results, heartbeat notifications, and autonomous decisions appear in the chat window without the user having to ask.
-
-** Why a Background Reader Thread?
-
-The daemon's protocol is framed TCP — the TUI sends a message, the daemon processes it, and sends one or more responses. But the daemon can also send unsolicited messages (heartbeat notifications, tool results from autonomous actions). The background reader thread handles this by continuously reading from the socket and enqueuing messages for the main loop to display.
-
-The main loop is event-driven: on each tick, it checks for new messages in the queue, checks for keyboard input, renders updates, and sleeps for ~10ms. This gives responsive text input (no perceived latency) while keeping CPU usage near zero.
-
-* Implementation
-
-** Package Context
-
-The TUI lives in its own package (~passepartout.gateway-tui~) so it doesn't pollute the harness namespace. It depends on Croatoan (ncurses bindings), usocket (TCP client), and bordeaux-threads (background reader).
-
-#+begin_src lisp
-(in-package :cl-user)

-** Connection state

-#+end_src
-
-#+begin_src lisp
-(defvar *daemon-port* 9105)
-#+end_src
-
-** Socket and stream
-
-The TCP socket and stream used to communicate with the daemon. Set during ~main~ and used by ~input-submit~ and ~reader-start~.
-
-#+begin_src lisp
-(defvar *socket* nil)
-#+end_src
-
-#+begin_src lisp
-(defvar *stream* nil)
-#+end_src
-
-** Chat history
-
-The list of messages displayed in the chat window. Each message is a string prepended with ~⬆~ (outgoing) or ~⬇~ (incoming).
-
-#+begin_src lisp
-(defvar *chat-history* nil)
-#+end_src
-
-** Input buffer
-
-The current line the user is typing. Characters are pushed onto this list and reversed before submission.
-
-#+begin_src lisp
-(defvar *input-buffer* nil)
-#+end_src
-
-** Running flag
-

-
-#+begin_src lisp
-(defvar *is-running* t)
-#+end_src
-
-** Incoming message queue
-
-Thread-safe queue for messages received by the background reader. Lock ensures the main loop and reader thread don't race on the list.
-
-#+begin_src lisp

-#+end_src
-
-** Rendering (chat-render)
-
-Renders the chat history window. Draws a bordered box with scrollable content — only the most recent ~h-2~ messages are visible, matching the window height.
-
-The box border uses Unicode box-drawing characters via Croatoan's ~box~ function.
-
-#+begin_src lisp
-(defun chat-render (win h)
-  (when (and win (integerp h))

-    (refresh win)))
-#+end_src

-
-Sends the accumulated input as a framed protocol message to the daemon. The message format is:
-
-  (:TYPE :EVENT :META (:SOURCE :tui) :PAYLOAD (:SENSOR :user-input :TEXT "<user input>"))
-
-Also handles the ~/exit~ and ~/clear~ client-side commands before sending to the daemon.

-** Background Reader (reader-start)
-
-A dedicated thread that continuously reads framed messages from the daemon's TCP stream. Messages are parsed and enqueued for the main loop to display.
-
-The reader handles:
-- The ~:handshake~ action (sent on connection) — displays "* Connected *"
-- All other actions — displays the ~:text~ payload or the raw payload
-
-If the connection is lost or an error occurs, the reader logs the error, enqueues a "Connection lost" message, and sets ~*is-running*~ to nil to stop the main loop.

-** Main Entry Point (main)
-
-The top-level entry point for the TUI application. Boot sequence:
-
-1. Connect to the daemon at ~localhost:9105~
-2. If connection fails, print an error and exit immediately
-3. Create the ncurses screen with two windows (chat + input)
-4. Start the background reader thread
-5. Enter the main loop: check for messages, check for keyboard input, render
-6. On ~unwind-protect~ cleanup: close the socket
-
-The main loop runs at ~100Hz (10ms sleep). Keyboard input is non-blocking — if no key is pressed, the loop still runs to check for incoming messages from the daemon.

+
+* 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.

+
+* Architectural Intent
+
+~system-model-provider~ is the universal LLM client. 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
+
+** Package Context
+
+#+begin_src lisp
+(in-package :passepartout)
+#+end_src
+
+** 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.
+
+Example:
+  MODEL_CASCADE_CODE='((:ollama . "deepseek-coder:6.7b") (:openrouter . "claude-sonnet"))'
+
+*** *model-cascade-code*

+** Cascade Lookup
+
+The core iterates each backend in ~*provider-cascade*~ and calls the model
+selector for each one. This function matches the current backend against the
+per-slot cascade list to find the appropriate model. Returns the first
+~:code~ ~(provider . model)~ entry whose provider matches, or ~nil~ if
+the backend has no entry in that slot's cascade (the core will skip to
+the next provider).

+** Model Selector
+
+The main routing function. Registered into ~*model-selector*~ at init time.
+Called per-backend by ~backend-cascade-call~. Returns a model name string,
+or ~:skip~ if the backend should not be tried (e.g., privacy filter).

 * 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.
 
-** Discipline Rules
+** Contract
 
-*** One Function, One Block
+1. (literate-extract-lisp-blocks content): extracts concatenated
-Every ~#+begin_src lisp~ block contains exactly one function definition. Never bundle multiple definitions in a single block. This keeps the Org file granular, reviewable, and tanglable without side effects.
+   Lisp code from all ~#+begin_src lisp~ blocks in an Org string.
-
+2. (literate-block-balance-check org-file): checks that parentheses are
-*** Prose Before Code
+   balanced across all lisp blocks in an Org file. Returns T or nil.
-Every block must be preceded by an Org headline and explanatory prose that covers:
+3. (literate-tangle-sync-check org-file lisp-file): verifies the
-- What the function does
+   tangled .lisp file matches the Org source. Returns T or mismatch info.
-- Its arguments (including any &key, &optional)
-- Its return value
-- The rationale for its existence
-
-The prose is not a comment — it is the authoritative specification. The code implements what the prose describes.
-
-*** Reflect Back, Don't Write Directly
-Code is explored and verified in the REPL first (per Engineering Standards lifecycle). Once working, it is *reflected back* into the Org file. This means:
-- The REPL is the proving ground — iterate there
-- The Org file is the record — copy working code there
-- Never write code directly into an Org block without first evaluating it in the REPL
-
-*** Code and Prose Together
-Every ~#+begin_src lisp~ block flows from the prose above it. The reader (human or agent) should understand the function's contract from the prose before reading the code. If the code and prose disagree, the prose is wrong — update both.
-
-*** Tangle Mandate
-The `.lisp` file is derived, not authored. Never edit `.lisp` directly. All changes flow through Org: edit Org → tangle → `.lisp` updates. Violating this corrupts the skill loader and causes boot failure.

 * 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 ~bouncer-privacy-tags~) and rejects files with matching ~#+FILETAGS:~.

 * 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**.
 
-** Engineering Lifecycle (Two-Track)
+** Architectural Intent + Testable Contract
 
-The canonical workflow. Two tracks, not to be confused:
+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.
 
-*** Track 1 — Org-First: Prose, Tests, Thinking (Phases 0/A)
+*** Template
 
-This track stays in Org. No code is written yet.
+Place this before ~* Implementation~ in every Org file:
-
-**** Phase 0: Exploration & Documentation
-1. Read the relevant Org source files for context
-2. Explore the problem in the running REPL with ~repl-inspect~ and ~repl-eval~
-3. Document findings in Org prose
-4. If a bug: document investigation in Org before fixing (Org as thinking medium)
-
-**** Phase A: Test-First Design
-1. Write the success criteria in Org prose — what the function does, arguments, return value, rationale
-2. Write the FiveAM test in a ~#+begin_src lisp :tangle no~ block
-3. Tangle the test and evaluate in the REPL — confirm it fails (red)
-4. The failing test is the success criteria. Do not proceed to Track 2 until it exists and is red.
-
-*** Track 2 — REPL-First: Implementation, Iteration, Reflection (Phases B/C/D/E)
-
-Code is prototyped in the REPL, never written directly into Org first.
-
-**** Phase B/C: REPL Implementation
-1. Write the function directly in the REPL using ~repl-eval~
-2. Iterate: evaluate, inspect, fix, re-evaluate — the image accumulates state
-3. Run the test in the REPL — confirm green
-4. Explore edge cases with ~repl-inspect~ and ad-hoc evaluations
-5. Before writing any ~defun~ in an Org block, verify it was prototyped and tested in the REPL first
-
-**** Phase D: Chaos Verification
-Run the appropriate chaos tier before reflecting code back to Org:
-- *Tier 1 (Deterministic)*: Full FiveAM test suite — required on every change
-- *Tier 2 (Probabilistic)*: Randomized fuzzing — required on every major release
-- *Tier 3 (Stress)*: Load and resource starvation — required during hardening sprints
-
-**** Phase E: Reflect Back to Org
-1. Copy the working function into its own ~#+begin_src lisp~ block in the Org file
-2. Update the prose to match what the function actually does (arguments, return, rationale)
-3. Before closing Phase E, run ~(utils-lisp-validate (uiop:read-file-string "path/to/file.lisp") :strict t)~ in the REPL — never external scripts or manual paren-counting
-4. Verify the Org file tangles correctly
-5. Tangle, commit, update GTD
-
-**** Syntax Error Protocol
-If a LOADER ERROR or reader-error occurs:
-1. Run ~(utils-lisp-validate (uiop:read-file-string "file.lisp") :strict t)~ in the REPL — never Python, never grep, never manual counting
-2. Fix the error in the Org file (since the code was prototyped in REPL first, this should be rare)
-3. Retangle and re-evaluate
-
-Rationale: The two tracks prevent the two failure modes we have observed. Writing implementation code directly in Org (without REPL prototyping) produces syntax errors that require external tools to debug. Skipping Org-first test writing produces code without verified success criteria. The split is not bureaucratic — it is the mechanism by which both failures are prevented.
-
-** GTD Conventions
-
-Every task headline in the project's ROADMAP.org and gtd.org follows these rules:
-
-1. **:ID:** — generated by ~memory-id-generate~ (UUIDv4 with ~id-~ prefix), never written manually. Use ~(memory-id-generate)~ in the REPL to produce one.
-2. **:CREATED:** — ISO-8601 timestamp: ~[2026-05-02 Sat 14:30]~. Set when the headline is first created, never changed.
-3. **:LOGBOOK:** — each state transition is logged: ~- State "DONE" from "TODO" [2026-05-02 Sat 15:00]~.
-4. **CLOSED:** — set when the task reaches DONE: ~CLOSED: [2026-05-02 Sat 15:00]~.
-5. **TODO keywords** follow the standard sequence: ~TODO~ → ~NEXT~ → ~IN-PROGRESS~ → ~DONE~ / ~BLOCKED~ / ~CANCELLED~.
-6. **The Agent** updates these automatically during Phase E of the lifecycle. The human never needs to write a UUID or timestamp manually — the agent generates and inserts them.

+
+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

+
+* 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 Bouncer calls before dispatching a tool action.
+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 default for any unregistered tool is ~:ask~ — cautious by default, permissive by configuration. This prevents a hallucinated tool call from executing without at least giving the user a chance to review it.
+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)~.

 * 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~). This prevents malformed messages from crashing the pipeline and ensures backward compatibility when the protocol evolves.
 
+* Architectural Intent
+
+The Protocol Validator wraps ~validate-communication-protocol-schema~
+(the core communication function) in a skill-level gate. It is the first
+filter every message passes through — malformed messages are rejected
+before they reach any cognitive stage.
+
+** Contract

+   through; invalid actions produce a ~:LOG~ rejection with

 * Overview
 The *Credentials Vault* provides secure in-memory storage for sensitive API keys and session tokens.
 
+* Architectural Intent
+
+The Credentials Vault isolates secrets from the rest of the system in
+a dedicated hash-table. It provides simple get/set primitives with
+environment-variable fallback for known providers. This is the single
+place where credentials enter the system — every provider skill routes
+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.

+
+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

 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.
