passepartout: v0.5.0 hotfix 2 — daemon stable

- Restore (in-package :passepartout) to core-reason
- Move *VAULT-MEMORY* back to core-skills
- Fix ASDF and defstruct/defpackage ordering
- Increase daemon timeout to 120s
- Handshake: 0.5.0

Verified: daemon processes messages, TUI clean, gate trace works

-* 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.

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

-#+PROPERTY: header-args:lisp :tangle ../lisp/system-context-manager.lisp
-
-* Overview
-
-The Context Manager provides stack-based project focusing. When the agent
-"focuses" on a project, file paths resolve relative to it and memory queries
-auto-filter by scope. This enables the agent to work within a bounded context
-without being distracted by unrelated memory.
-
-The core provides the mechanism (=memory-object-scope=, =context-query= with
-scope parameter). This skill provides the policy — what to focus on, what
-scope means for each project, and how the stack is managed.
-

-* Why a Doctor?
-
-The Diagnostics skill is the self-knowledge of Passepartout. It answers "Is everything working?" by checking dependencies, environment variables, and LLM connectivity. Unlike the harness-level Doctor (which runs at boot and on CLI demand), this skill provides the Lisp-level diagnostic functions — defining what "healthy" means: which binaries must be present, which directories must exist, which API keys should be configured.
-
-* Phase A: Demand (Thinking)
-** Why a Doctor?
-The Doctor transforms opaque startup failures into actionable engineering reports. It ensures the Brain never attempts to boot in a compromised state.
-
-** Detection Invariant
-Binary detection must use shell probing (`which`) to account for varying `$PATH` inheritance between interactive and headless sessions.
-
-* Phase B: Contract
-
-1. (diagnostics-dependencies-check): probes PATH for every binary in
-   ~*diagnostics-binaries*~. Returns T if all found, NIL if any missing.
-   Side-effect: populates ~*doctor-missing-deps*~.
-2. (diagnostics-env-check): validates XDG directories exist. Returns T
-   if all critical dirs present, NIL otherwise.
-3. (diagnostics-run-all &key auto-install): orchestrates 1-3. Returns
-   a plist with ~:deps~, ~:env~, ~:llm~ keys. Respects ~:auto-install nil~.

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

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

+#+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~.

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

-* 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)

-** Embedding inference
-
-Computes a 768-dim single-float vector for the given text via llama.cpp.
-
-Pipeline:
-1. Load/cache model + context
-2. Tokenize text via =llama_tokenize= (takes =vocab*= not =model*= since v0.4.1)
-3. Initialize batch via C wrapper (=llama_batch_init= returns struct-by-value)
-4. Fill batch: set =tokens=, =pos=, =n_seq_id=, =seq_id[0]=, =logits= for each position
-5. CRITICAL: set =batch.n_tokens= explicitly — =llama_batch_init= initializes it to 0
-6. Encode via C wrapper (=llama_encode= takes struct-by-value batch)
-7. Extract pooled embedding via =llama_get_embeddings_seq= (BERT CLS pooling)
-   — falls back to =llama_get_embeddings_ith= if =pooling_type == NONE=
-8. Free batch memory via wrapper (=llama_batch_free= takes struct-by-value)
-
-NOTE: we write =seq_id= values directly into the arrays allocated by
-=llama_batch_init= (not foreign-alloc'd separately) to avoid double-free.

-* 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.

-* 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*~.

-* 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

-#+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*

-
-* 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.
