v0.3.2: shell safety, :system :eval approval, skill sandbox

1. Shell actuator: remove double bash -c wrapping (format ~s produces
   S-expression-safe strings, not shell-safe). Now passes cmd directly
   to (timeout N bash -c cmd) via run-program arg list.

2. Dispatcher: extend high-impact approval gate to :system :eval.
   Previously only :shell, :tool "shell", and :emacs :eval triggered
   HITL. Now :system :eval also requires Flight Plan approval.

3. Skill sandbox: before promoting a skill from its jailed package to
   :passepartout, scan for restricted symbol references (uiop:run-program,
   uiop:shell, uiop:run-shell-command). Block promotion on violation.
   New skill-entry status :sandbox-blocked for blocked skills.

Test: 91 pass, 0 fail across 13 suites.

+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 nine 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 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: nine 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. 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.
+
+Passepartout has a downward cost curve. This runs counter to every other AI agent.
+
+Here is why. 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.
+
+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.
+
+Other agents grow more expensive over time (context histories accumulate, safety instructions grow). Passepartout's cost curve bends down.
+
+** 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 nine deterministic safety gates are pure Common Lisp — they run identically whether you are online or off. The Merkle-tree memory with snapshot rollback is in-process, 0 milliseconds, 0 network calls. Semantic retrieval runs on in-image vectors, 0 LLM tokens per query.
+
+Cloud providers (OpenRouter, OpenAI, Anthropic, Groq, Gemini, DeepSeek, NVIDIA NIM...) are optional add-ons. When you use them, the model-tier router automatically selects the cheapest provider that matches your task's complexity. Privacy-tagged content stays local even when cloud providers are configured.
+
+* How It Works
+
+Every signal — a chat message, a heartbeat tick, a file change notification — moves through three stages:
+
+#+begin_example
+Signal  →  Perceive  →  Reason  →  Act
+            normalize    LLM proposes  dispatch approved action
+                         gates verify  tool output feeds back
+#+end_example
+
+*Perceive* normalizes raw input from any gateway (TUI, CLI, Telegram, Signal) into a uniform signal plist. Buffer updates from Emacs ingest Org AST nodes into memory. Heartbeat ticks trigger background maintenance. HITL commands intercept before the LLM is invoked.
+
+*Reason* calls the LLM to generate a proposal, then runs the proposal through every registered deterministic gate — sorted by priority, highest first. If a gate rejects (shell command blocked, path protected, secret exposed), the rejection trace feeds back to the LLM for self-correction, up to three retries. If a gate requests human approval, the action becomes a Flight Plan awaiting your decision. If all gates pass, the action proceeds to Act.
+
+*Act* dispatches the approved action to the correct actuator: shell commands go to the shell actuator (with timeout and output limiting), tool invocations go to the cognitive tool registry, system commands trigger internal harness operations, and chat responses route to the TUI or messaging gateway. Each stage can feed back into Perceive — a tool output becomes the next perception.
+
+This pipeline is not a single-threaded bottleneck. The priority-queued signal processor (v0.5.0 roadmap) preempts background maintenance for user interactions. The Merkle-tree memory supports concurrent reads and writes through versioned snapshots — multiple signals can process simultaneously without corrupting shared state.

-* 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.

+Nodes that don't match any rule are rendered as title-only — a single Org headline with its :ID: property. This keeps active context between 2,000–4,000 tokens for typical memex sizes, versus 50,000–150,000 tokens for a full serialization. The embedding vectors that power semantic retrieval are computed at ingest time (~ingest-ast~ in core-memory.lisp) and can use local models (Ollama), cloud APIs (OpenAI embeddings), or a zero-dependency lexical fallback (trigram Jaccard similarity).
+
+For the rationale behind sparse-tree rendering and why this architecture outperforms "load everything" systems, see Design Decisions: Org-Mode as Unified AST.
+
+* Dispatcher Gate Stack
+
+Every action the LLM proposes passes through a stack of deterministic gates before execution. Gates are registered as skills with ~defskill~ and sorted by priority (highest first) in ~cognitive-verify~ (core-loop-reason.lisp).
+
+| Priority | Gate                      | What It Checks                                           |
+|----------+---------------------------+----------------------------------------------------------|
+| 600      | security-permissions      | Tool permission table (allow/ask/deny per tool)          |
+| 600      | security-vault            | Credential storage integrity                             |
+| 500      | security-policy           | Requires :explanation on every action                    |
+| 150      | security-dispatcher       | 9-vector safety: secrets, paths, shell, lisp, network,   |
+|          | (the Dispatcher)          | privacy, 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.

+- Pure Common Lisp + Org-mode. No JSON. No YAML. No external databases.
+- Single-address-space memory (Lisp hash tables in RAM — the agent IS the memory).

+This is the foundational decision from which all other decisions derive. It is not negotiable. Every architectural choice below exists because this identity makes it possible — and in some cases, makes it the only viable path. The single memory space enables Merkle-tree integrity without serialization boundaries. Plists enable the cognitive pipeline to be transparent and inspectable at every stage. Org-mode as the universal format means the agent's memory, the user's notes, and the agent's own source code are the same structure. This identity is the constraint that produces the architecture.

-* The Probabilistic-Deterministic Split
-:PROPERTIES:
-:ID:       design-probabilistic-deterministic
-:END:
-
-The architecture divides cognition into two fundamentally different reasoning systems. This is not arbitrary engineering but a structural response to a fundamental truth: probabilistic systems will hallucinate, and you cannot build reliable autonomy on an unreliable foundation.
-
-An LLM is a statistical engine. It generates outputs based on patterns in training data. It is remarkable at translation, generation, pattern matching, and fuzzy reasoning. It can take messy human intent and produce structured queries. It can take structured results and produce natural language. It is, in the terminology of the system, the creative brain.
-
-But it cannot be trusted. Not because it is poorly designed or insufficiently trained, but because hallucination is a fundamental property of probabilistic inference. The model generates the most likely continuation, not the correct one. Given sufficient context, the most likely continuation is correct. Given novel context, it is often wrong in confident-sounding ways.
-
-The deterministic engine addresses this by being what the probabilistic engine is not: mathematically rigorous, formally verifiable, and incapable of hallucination by design. It operates on explicit symbolic representations - lists, property lists, knowledge graphs - not on floating-point activations. When it evaluates a path confinement check, it returns true or false, not a probability distribution.
-
-The division of labor is architectural. The LLM handles the fuzzy interface between human language and structured representation. It translates what the user wants into what the system can reason about. The deterministic engine receives those structured representations and evaluates them against formal invariants. It decides whether to execute, not whether the translation was semantically plausible.
-
-This separation is the source of Passepartout's safety guarantee. Other agents add "guardrails" as an afterthought - a layer of filtering around a dangerous core. Passepartout makes the division explicit: the LLM never touches the file system, never executes a command, never modifies memory. It generates proposals. The deterministic engine evaluates and executes. The dangerous operations are never in the probabilistic path.
-
-The split also explains why the system gets safer over time without the LLM improving. The deterministic engine accumulates rules. The LLM proposes actions, the engine evaluates them against a growing rule set. Early versions block obvious dangers. Later versions block sophisticated attacks that were previously unknown. The safety grows logarithmically with the number of interactions, not linearly with model capability.
-
-* Homoiconicity as Foundation
-:PROPERTIES:
-:ID:       design-homoiconicity
-:END:
-
-Common Lisp is homoiconic: code and data share the same representation. A Lisp program is a list, and a list is a Lisp program. This is usually presented as a curiosity, an interesting property that enables macros. In Passepartout, it is the foundational enabling property of the entire self-modification architecture.
-
-When code is data, the agent can read its own source the same way it reads a text file or an Org buffer. There is no AST parser required, no external tool to extract the function object from the running image. The agent evaluates (read-from-string source) and the result is executable Lisp. The representation it manipulates is the same representation that the runtime executes.
-
-This is not true of most languages. In Python, the agent can inspect an AST through the ast module, but that AST is a foreign object - a data structure that represents code but is not code itself. The agent can see that a function takes certain arguments and returns a certain type, but it cannot treat the AST as a live object it can modify and re-evaluate. In C, the agent cannot inspect its own compiled machine code at all.
-
-In Lisp, the distinction between code and data is a convention, not a barrier. The agent's skills are lists. The agent can take a skill, extract a function definition, modify the body, wrap it in a new list, and evaluate it. The modification is surgical: it changes exactly what it intends to change, with no risk of corrupting adjacent state, because the representation is a tree that the runtime understands natively.
-
-Runtime introspection is therefore native. The agent does not need a debugger API or a reflection protocol. It operates on its own code as data because its own code is data. (describe 'function-name) returns the function's documentation. (function-lambda-list 'function-name) returns its parameters. (macroexpand-1 '(defskill ...)) shows what the macro produces. There is no impedance mismatch between the agent's reasoning and the system's representation.
-
-Self-modification is the practical consequence. The agent can detect an error, locate the erroneous function, generate a corrected version, and hot-reload it into the running image. The correction is not applied to a file that requires a restart - it is applied to the live object that the system is currently executing. This is what makes the self-editing skill viable: the agent can fix itself without stopping.
-
-In v3.0.0, when the symbolic engine takes over the reasoning core, homoiconicity becomes the bridge between the neural and symbolic layers. The neural engine generates proposals as s-expressions. The symbolic engine evaluates them against formal constraints. The result is a modification that is simultaneously a data structure the symbolic engine can analyze and code the runtime can execute. The two representations are identical by construction.
-
-This is the technical meaning of "Lisp as Governor": not just that Lisp orchestrates the other components, but that the representation of the system is uniform and inspectable at every level. There is no hidden state, no opaque machine code, no representation that the agent cannot reach into and modify. The system is legible to itself by design.
-
-*Self-Modification Without Boundaries*
-
-Other systems that support self-editing draw a line between the core and the skills. Hermes can modify its skills at runtime, but the core harness is protected - editing it requires a restart because the core is treated as privileged code that cannot be safely modified while running.
-
-Passepartout has no such boundary. The "thin harness, fat skills" distinction describes where complexity lives, not where authority flows. The harness is small by design, but it is not privileged. The agent can read and write any part of the system - including the very code that is currently executing - without restarting.
-
-This is only possible because Lisp code is mutable data at runtime. In a compiled language, the machine code for a running function is locked in memory, protected by the call stack, impossible to modify safely. In Lisp, the function object is a list you can modify with =setf=. When the agent changes a harness function, the running image immediately reflects the change. The next invocation uses the new code. There is no restart, no special boot mode, no distinction between development and production.
-
-The implications extend beyond convenience. A system that cannot modify its own core is a system that has limits on its own adaptability. It can learn skills but not improve its own structure. It can grow but not evolve. Passepartout's lack of a core boundary means the system can improve its own reasoning engine, fix bugs in its own cognition, and evolve its own architecture - all while continuing to operate.
-
-This is the final expression of homoiconicity: not just that code is readable as data, or that skills are modifiable, but that the entire system - including the parts that other systems protect - is open to modification. There is no ceiling on self-improvement. The agent can rewrite the very code that rewrites itself.
-
-*Lisp and the AI Dream*
-
-Lisp was invented in 1958 by John McCarthy with artificial intelligence explicitly in mind. Its design - code as data, runtime mutation, symbols and lists as first-class constructs - was shaped by the belief that a truly intelligent machine would need to reason about and modify its own reasoning. For decades, Lisp machines were the closest thing to thinking machines that existed.
-
-Then the AI winter came. Symbolic AI fell out of favor. Statistical learning and neural networks dominated. Lisp was relegated to niche applications and academic curiosity. The machine that was designed for AI was never used for the task it was designed for.
-
-Six decades later, neural networks have arrived at the problem from a different direction. They can learn and generalize, but they hallucinate, cannot explain their reasoning, and cannot safely modify themselves. The neuro-symbolic synthesis - combining neural pattern recognition with symbolic reasoning - is recognized as the path toward AI that is both powerful and trustworthy.
-
-Lisp's time may finally have come. Not as a replacement for neural networks, but as the governor that makes them safe - the symbolic engine that verifies what the neural engine proposes, the homoiconic substrate that allows the system to inspect, modify, and improve its own reasoning. The machine that was designed for AI in 1958 may be the exact machine needed for AI in 2026 and beyond.

-The decision to use Org-mode as the source of truth for code, not just documentation, is not a ceremonial preference. It is a constraint mechanism that enforces better engineering habits at the cost of convenience.
+Common Lisp is homoiconic: code and data share the same representation. A Lisp program is a list, and a list is a Lisp program. This is usually presented as a curiosity, an interesting property that enables macros. In Passepartout, it is the foundational enabling property of the entire self-modification architecture.
 
-The traditional development workflow is: write code, write comments, commit. The literate programming workflow is: write prose, write code, commit the Org. The order matters. The prose must come first not because of style guidelines but because the act of explaining what a function does before writing it forces clarity of thought that editing code directly does not.
+When code is data, the agent can read its own source the same way it reads a text file or an Org buffer. There is no AST parser required, no external tool to extract the function object from the running image. The agent evaluates (read-from-string source) and the result is executable Lisp. The representation it manipulates is the same representation that the runtime executes.
 
-When you must write a paragraph describing what a function does before you write the function, you discover the cases you have not considered. You find the edge conditions that are ambiguous. You realize that the function's name does not match its behavior, or that its behavior does not match your intent. The friction is not a bug - it is the mechanism by which thinking is enforced.
+This is not true of most languages. In Python, the agent can inspect an AST through the ast module, but that AST is a foreign object - a data structure that represents code but is not code itself. The agent can see that a function takes certain arguments and returns a certain type, but it cannot treat the AST as a live object it can modify and re-evaluate. In C, the agent cannot inspect its own compiled machine code at all.
 
-The one-function-per-block rule enforces granularity. A function that cannot be explained in a paragraph is a function that is doing too much. The block boundary is not aesthetic - it is architectural. It prevents the drift toward monolithic functions that accumulate responsibilities over time and become untestable, unmaintainable, and incomprehensible.
+In Lisp, the distinction between code and data is a convention, not a barrier. The agent's skills are lists. The agent can take a skill, extract a function definition, modify the body, wrap it in a new list, and evaluate it. The modification is surgical: it changes exactly what it intends to change, with no risk of corrupting adjacent state, because the representation is a tree that the runtime understands natively.
 
-The tangle step enforces source-of-truth discipline. The .lisp file is generated from the Org file. This means the Org file cannot drift from the implementation. If the implementation changes, the Org must be updated to match. If the Org describes behavior that the implementation does not perform, the tangle produces code that does not match the Org description. Either way, inconsistency is visible and recoverable.
+Runtime introspection is therefore native. The agent does not need a debugger API or a reflection protocol. It operates on its own code as data because its own code is data. (describe 'function-name) returns the function's documentation. (function-lambda-list 'function-name) returns its parameters. (macroexpand-1 '(defskill ...)) shows what the macro produces. There is no impedance mismatch between the agent's reasoning and the system's representation.
 
-The evaluation gate enforces correctness. Every block can be evaluated independently in a running Lisp image. This means syntax errors are caught at authorship time, not at integration time. The function that compiles in isolation but fails in context is the function whose context dependencies were never made explicit. The evaluation gate forces those dependencies to surface.
+Self-modification is the practical consequence. The agent can detect an error, locate the erroneous function, generate a corrected version, and hot-reload it into the running image. The correction is not applied to a file that requires a restart - it is applied to the live object that the system is currently executing. This is what makes the self-editing skill viable: the agent can fix itself without stopping.
 
-Together, these constraints create a development experience that is slower in the small and faster in the large. Writing a new function takes longer because you must explain it. But debugging, maintaining, and extending the codebase is faster because every function has a human-readable explanation of its intent, every function is testable in isolation, and every function's source is always synchronized with its documentation.
+In v3.0.0, when the symbolic engine takes over the reasoning core, homoiconicity becomes the bridge between the neural and symbolic layers. The neural engine generates proposals as s-expressions. The symbolic engine evaluates them against formal constraints. The result is a modification that is simultaneously a data structure the symbolic engine can analyze and code the runtime can execute. The two representations are identical by construction.
 
-The literate programming discipline is not about producing documentation. It is about producing code whose correctness has been verified by the act of explaining it.
+This is the technical meaning of "Lisp as Governor": not just that Lisp orchestrates the other components, but that the representation of the system is uniform and inspectable at every level. There is no hidden state, no opaque machine code, no representation that the agent cannot reach into and modify. The system is legible to itself by design.
 
-* The Dispatcher as Learning System
+*Self-Modification Without Boundaries*
+
+Other systems that support self-editing draw a line between the core and the skills. Hermes can modify its skills at runtime, but the core harness is protected - editing it requires a restart because the core is treated as privileged code that cannot be safely modified while running.
+
+Passepartout has no such boundary. The "thin harness, fat skills" distinction describes where complexity lives, not where authority flows. The harness is small by design, but it is not privileged. The agent can read and write any part of the system - including the very code that is currently executing - without restarting.
+
+This is only possible because Lisp code is mutable data at runtime. In a compiled language, the machine code for a running function is locked in memory, protected by the call stack, impossible to modify safely. In Lisp, the function object is a list you can modify with =setf=. When the agent changes a harness function, the running image immediately reflects the change. The next invocation uses the new code. There is no restart, no special boot mode, no distinction between development and production.
+
+The implications extend beyond convenience. A system that cannot modify its own core is a system that has limits on its own adaptability. It can learn skills but not improve its own structure. It can grow but not evolve. Passepartout's lack of a core boundary means the system can improve its own reasoning engine, fix bugs in its own cognition, and evolve its own architecture - all while continuing to operate.
+
+This is the final expression of homoiconicity: not just that code is readable as data, or that skills are modifiable, but that the entire system - including the parts that other systems protect - is open to modification. There is no ceiling on self-improvement. The agent can rewrite the very code that rewrites itself.

+** The Probabilistic-Deterministic Split
+:PROPERTIES:
+:ID:       design-probabilistic-deterministic
+:CREATED:  [2026-05-07 Wed]
+:END:
+
+The architecture divides cognition into two fundamentally different reasoning systems. This is not arbitrary engineering but a structural response to a fundamental truth: probabilistic systems will hallucinate, and you cannot build reliable autonomy on an unreliable foundation.
+
+An LLM is a statistical engine. It generates outputs based on patterns in training data. It is remarkable at translation, generation, pattern matching, and fuzzy reasoning. It can take messy human intent and produce structured queries. It can take structured results and produce natural language. It is, in the terminology of the system, the creative brain.
+
+But it cannot be trusted. Not because it is poorly designed or insufficiently trained, but because hallucination is a fundamental property of probabilistic inference. The model generates the most likely continuation, not the correct one. Given sufficient context, the most likely continuation is correct. Given novel context, it is often wrong in confident-sounding ways.
+
+The deterministic engine addresses this by being what the probabilistic engine is not: mathematically rigorous, formally verifiable, and incapable of hallucination by design. It operates on explicit symbolic representations - lists, property lists, knowledge graphs - not on floating-point activations. When it evaluates a path confinement check, it returns true or false, not a probability distribution.
+
+The division of labor is architectural. The LLM handles the fuzzy interface between human language and structured representation. It translates what the user wants into what the system can reason about. The deterministic engine receives those structured representations and evaluates them against formal invariants. It decides whether to execute, not whether the translation was semantically plausible.
+
+This separation is the source of Passepartout's safety guarantee. Other agents add "guardrails" as an afterthought - a layer of filtering around a dangerous core. Passepartout makes the division explicit: the LLM never touches the file system, never executes a command, never modifies memory. It generates proposals. The deterministic engine evaluates and executes. The dangerous operations are never in the probabilistic path.
+
+The split also explains why the system gets safer over time without the LLM improving. The deterministic engine accumulates rules. The LLM proposes actions, the engine evaluates them against a growing rule set. Early versions block obvious dangers. Later versions block sophisticated attacks that were previously unknown. The safety grows logarithmically with the number of interactions, not linearly with model capability.

+The decision to use Org-mode as the source of truth for code, not just documentation, is not a ceremonial preference. It is a constraint mechanism that enforces better engineering habits at the cost of convenience.
+
+The traditional development workflow is: write code, write comments, commit. The literate programming workflow is: write prose, write code, commit the Org. The order matters. The prose must come first not because of style guidelines but because the act of explaining what a function does before writing it forces clarity of thought that editing code directly does not.
+
+When you must write a paragraph describing what a function does before you write the function, you discover the cases you have not considered. You find the edge conditions that are ambiguous. You realize that the function's name does not match its behavior, or that its behavior does not match your intent. The friction is not a bug - it is the mechanism by which thinking is enforced.
+
+The one-function-per-block rule enforces granularity. A function that cannot be explained in a paragraph is a function that is doing too much. The block boundary is not aesthetic - it is architectural. It prevents the drift toward monolithic functions that accumulate responsibilities over time and become untestable, unmaintainable, and incomprehensible.
+
+The tangle step enforces source-of-truth discipline. The .lisp file is generated from the Org file. This means the Org file cannot drift from the implementation. If the implementation changes, the Org must be updated to match. If the Org describes behavior that the implementation does not perform, the tangle produces code that does not match the Org description. Either way, inconsistency is visible and recoverable.

-The simplest deployment is one that requires no installation steps. The user downloads one file, runs it, and the system works. Passepartout approximates this through SBCL's ability to produce standalone executables via save-lisp-and-die. The executable contains the Lisp runtime, the compiled system, and Quicklisp libraries - everything bundled into one binary.
-
-The practical reality is more nuanced. Building a truly standalone executable requires resolving all library dependencies at build time and embedding them in the binary. SBCL supports this, but the resulting binary is large (tens of megabytes), and updating any component requires a full rebuild. The current deployment model uses a Docker container that maps the user's memex directory as a volume. The container starts, loads the system, and is ready. No compilation on the user's machine, no dependency installation, no platform-specific quirks.
-
-The long-term goal is a single =passepartout= binary that the user runs. It starts a local web server on a Unix domain socket. The TUI connects through the socket. The user's Org files are in =~/memex/=. The binary is the only thing that needs to be installed.
-
-This stands in stark contrast to most AI agent systems, which require managing Python environments, npm packages, API keys, environment variables, and configuration files. OpenAI's agents SDK requires pip install, a Python environment, and external API access. OpenClaw requires Node.js, npm, and a plugin ecosystem that must be individually installed. LangChain requires a Python environment with dozens of dependencies that must be kept compatible.
-
-Passepartout's dependency model is SBCL plus Quicklisp. Quicklisp loads libraries on demand from the internet, but caches them locally. A system with internet access can fetch any library it needs. A system without internet access uses only the libraries it has already loaded - and those are preserved in the cache. The agent does not require internet access to function after initial setup.
+*On live images and binaries.* Passepartout's primary delivery path is source code running in a live SBCL process. The REPL is available. Skills hot-reload. The cognitive loop runs in an image that is mutable, inspectable, and homeiconic — the user can connect with SLIME, trace functions, inspect memory objects, and modify the system while it runs. A ~save-lisp-and-die~ binary is provided as a convenience for platforms where SBCL cannot be installed (corporate laptops, shared hosts). The binary is the same image saved to disk with Swank pre-loaded — it is not a sealed container. The REPL works. Skills hot-reload. The binary is a packaging format, not an architectural decision.

+When connected via the TUI, the following commands are available (type them in the input area and press Enter):
+
+| Command               | Action                                                 |

+For multi-line input, start the line with ~\~ then press Enter to insert a newline without sending.
+
+** Human-in-the-Loop Approval
+
+When the Dispatcher blocks a high-risk action (shell command, network call, core file modification), it creates a Flight Plan requiring your approval.
+
+1. The TUI displays a yellow message: ~→ HITL required: /approve HITL-ab12~
+2. Review the proposed action in the Dispatcher trace (expand with Tab)
+3. Type ~/approve HITL-ab12~ to approve, or ~/deny HITL-ab12~ to deny
+4. Approved actions are re-injected into the pipeline and executed
+5. Denied actions are discarded and the Dispatcher records the decision as a permanent rule
+
+Each approval or denial teaches the Dispatcher — the rule counter in the status bar (~[Rules: 47]~) increments with every decision.

-
-* 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)
-- Model-tier routing / cost optimization (v0.3.0 TODO)
-- Memory scope segmentation (v0.3.0 TODO)
-- Long-horizon planning / task trees (v0.4.0 TODO)
-- Shadow simulation mode (not on roadmap, aspirational)
-- Formal verification of dispatcher rules (not on roadmap, aspirational)
-- Bouncer rule learning from HITL decisions (not on roadmap, aspirational)

-* 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.
-
-* Implementation
-
-** Provider registry (~*provider-configs*~)
-The authoritative list of supported LLM providers and their configuration: base URL, env var for API key, and default model name.

-** 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.

 * 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.

-The LLM Gateway dispatches inference requests to the registered probabilistic backends.

 * 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.
+~gateway-messaging~ bridges Passepartout to external messaging platforms — Telegram, Signal, and any future service that speaks HTTP or has a CLI.
 
-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
+Each gateway follows the same pattern:
+1. **Registration** — a poll function and a send function are registered in ~*gateway-registry*~ by name ("telegram", "signal")
+2. **Linking** — the user provides a token (Telegram bot token) or account name (Signal CLI); it's stored in the vault and a polling thread starts
+3. **Polling** — the background thread calls the poll function every N seconds; inbound messages are injected into the daemon as ~:EVENT~ signals via ~stimulus-inject~
+4. **Sending** — when ~telegram-send~ or ~signal-send~ is invoked as an actuator (registered via ~register-actuator~), it formats the message and pushes it through the platform's API
+
+The gateway management functions (~messaging-link~, ~messaging-unlink~, ~messaging-list~, ~messaging-list-print~) are what the CLI's =passepartout gateway= subcommand calls. The old ~gateway-manager~ skill had ~gateway-link~/~gateway-unlink~/~gateway-list~ printed with the same signatures; the rename to ~messaging-*~ aligns the public API with the skill name while keeping the internal engine functions (~gateway-start~, ~gateway-stop~) as-is since they're implementation details.
+
+This replaces the old ~gateway-manager~ skill. The Telegram/Signal platform code is unchanged; only the management entry points and the defskill name changed.
+
+** Contract
+
+1. (gateway-registry-initialize): populates ~*gateway-registry*~ with
+   ~:configured~ key per platform (boolean, set when linked).
+2. (messaging-link platform &key token): stores the token in the vault
+   and starts the gateway's polling thread.
+3. (messaging-unlink platform): removes the token and stops the thread.
+4. (gateway-configured-p platform): returns T if platform is configured.
+5. (gateway-start platform): starts the background poll thread for a
+   named gateway platform.

+   input buffer, pushes history, sends to daemon, clears buffer),
+   ~\\ + Enter~ inserts a literal newline (multi-line input),
+   ~/help~ lists all commands, ~/eval <expr>~ evaluates a Lisp
+   expression, ~/focus <proj>~ switches project context,
+   ~/scope <scope>~ changes context scope, ~/unfocus~ pops context,
+   Tab completes command names, Backspace deletes, arrows scroll
+   chat and history. Non-printable keys are ignored.
+2. (on-daemon-msg msg): processes inbound daemon messages. Routes
+   text responses to chat display (:agent), handshake to system
+   messages, routes errors to log via ~log-message~.
+3. (send-daemon msg): serializes and sends a message to the daemon
+   over the framed TCP protocol.
+4. (tui-main): the main loop — connects to daemon, initializes
+   Croatoan windows, optionally starts Swank REPL, runs
+   render/input event loop at ~30fps.

-#+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 three-pane interface: a status
-bar at top, scrollable chat history in the middle, 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.
-
-* 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).

 * 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
-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.
-
-*** Prose Before Code
-Every block must be preceded by an Org headline and explanatory prose that covers:
-- What the function does
-- 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.
+1. (literate-extract-lisp-blocks content): extracts concatenated

 * 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:~.
 
+** Contract
+
+1. (org-id-generate): returns a new UUID string.

-* Overview
-
-Provider-agnostic vector embedding gateway. Generates dense vectors for
-~memory-object~ entries via a pluggable backend, enabling semantic similarity
-search. Designed for thin harness: the core (core-context) knows how to USE
-vectors but not how to GENERATE them — that lives here.
-
-Backends are configured via ~EMBEDDING_PROVIDER~:
-- ~:hashing~ (default) — FNV-1a hashing trick, no external dependencies
-- ~:ollama~ — POST /api/embeddings to a local Ollama instance
-
-Newly ingested objects are queued for embedding via ~embed-queue-object~.
-The ~embed-all-pending~ function drains the queue on heartbeat ticks, with
-a store-wide scan as fallback for objects ingested before the skill loaded.

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

+
+* Architectural Intent
+
+~system-model-embedding~ converts text into vector representations for semantic search and memory retrieval. It provides three backends:
+
+- ~:local~ — any OpenAI-compatible ~/api/embeddings~ endpoint (Ollama, vLLM, etc.)
+- ~:openai~ — the OpenAI ~/v1/embeddings~ API with an API key
+- ~:hashing~ — a zero-dependency fallback that produces deterministic vectors from SHA-256 hashes. No server, no config, works offline.
+
+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 ~:hashing~ — useful for bootstrapping with zero configuration and for deployments where embedding quality isn't critical. Switch to ~:local~ or ~:openai~ when you have an embedding server available.
+
+This replaces the old ~system-embedding-gateway~ with the same logic but renamed to ~system-model-embedding~ to live alongside the other ~system-model-*~ skills.

+* Architectural Intent
+
+~system-model-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-cascade-initialize): reads ~PROVIDER_CASCADE~ from env and
+   sets ~*provider-cascade*~.

+#+AUTHOR: Agent
+#+FILETAGS: :skill:model:dispatch:
+#+PROPERTY: header-args:lisp :tangle ../lisp/system-model.lisp
+
+* Architectural Intent
+
+~system-model~ is the dispatcher. It sits between the reason pipeline and the provider backends registered in ~*probabilistic-backends*~. The reason pipeline calls ~model-request~ with a provider keyword and a model name; ~model-request~ looks up that provider's handler function, calls it, and returns the result.
+
+This is intentionally thin. All the provider-specific logic (URL construction, API key headers, JSON parsing) lives in ~system-model-provider~. All the routing logic (which model for which task) lives in ~system-model-router~. This skill is the seam — it decouples "who to call" from "how to call them" and "why to call them."
+
+When every provider fails (not registered, or all return errors), ~model-request~ returns an error plist with ~:status :error~. The reason pipeline's ~backend-cascade-call~ catches this and falls through to the next provider in the cascade. If no provider can serve the request, the cascade returns the "Neural Cascade Failure" signal.
+
+~model-request~ replaces the old ~gateway-llm-request~ with the same contract but renamed for consistency with the ~system-model-*~ family.
+
+* Implementation
