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).

In Passepartout, context is stored once in the Lisp image. A 10-turn session pays for ~10 turns of context. This is an ~82% reduction on protocol overhead alone, before any foveal-peripheral pruning. This argument is testable: send the same multi-turn session through both architectures and count tokens.
 
+5. *Temporal filtering* — time-scoped memory queries (what happened today? what's due in the next hour?) return only nodes matching the time window. The temporal filter is a pure-Lisp hash-table walk with a numeric comparison on ~memory-object-version~. Sub-millisecond. 0 LLM tokens. Competitors without time-indexed memory must serialize all nodes and let the LLM scan for temporal relevance — 5,000–50,000 tokens per temporal query. This is the same principle as the foveal-peripheral model applied to the time dimension.

 ** The Compounding Cost Curve — Unique Among Agents
 
 Every AI agent grows more expensive over time. Context histories accumulate. Safety instructions grow more elaborate. Guardrails become longer prompt paragraphs. The user's data grows. The only way to reduce cost in a standard agent is to cap context — sacrificing capability.
@@ -343,6 +345,24 @@ Passepartout has a downward cost curve. Four mechanisms compound:
 
 After 12 months of daily use, Passepartout's per-session costs are expected to be 40–60% of baseline, while competitors' costs rise to 125–140% of baseline. The crossover point is estimated at 3–6 months. This is not a model quality claim — it is a structural property of the architecture.
 
+** Time Awareness as a Structural Advantage
+:PROPERTIES:
+:ID:       design-time-awareness
+:CREATED:  [2026-05-07 Thu]
+:END:
+
+Passepartout's architecture provides three layers of time awareness, each enabled by infrastructure that competitors lack:
+
+*Level 1 — Present Awareness.* The LLM knows the current time, date, and session duration because a single ~format-time-for-llm~ call injects it into the system prompt. Most agents know the date from the OS. None know the time or session duration. The cost is ~8 incremental tokens per call (trivially prefix-cached). The saving is eliminating "I don't know the current time" preamble tokens, time-check tool calls, and incorrect temporal reasoning from a model guessing the time.
+
+*Level 2 — Temporal Memory.* Memory queries accept ~:since~ and ~:until~ parameters. "What did I work on in the last hour?" filters 500 nodes to 12 in sub-millisecond Lisp rather than serializing 500 nodes to the LLM at ~5,000 tokens for it to scan. Every memory node carries a ~memory-object-version~ timestamp (a monotonic ~get-universal-time~ value set at ingest since v0.1.0). The temporal filter is a hash-table walk with numeric comparison. 0 LLM tokens. >90% token reduction on time-scoped queries.
+
+*Level 3 — Proactive Triggers.* The heartbeat tick (existing infrastructure since v0.3.0) scans for approaching deadlines every 60 seconds. When a deadline is within the warning window (~DEADLINE_WARNING_MINUTES~, default 60), a temporal context note is injected into the awareness assembly. The LLM sees "3 deadlines today: Submit report (45min)" in its context without a triggering call. A "what should I work on today?" query is answered from pre-loaded context — 0 LLM tokens versus 1,500–4,000 for an unassisted agent.
+
+None of these three layers require new infrastructure. Time awareness is not a feature Passepartout builds — it is a feature Passepartout *unlocks* by having timestamped memory (v0.1.0), heartbeat+cron (v0.3.0), and the foveal-peripheral context pruning model (v0.2.0) already in place. Adding time awareness costs ~175 lines of Lisp. Building it in competitors would require building the heartbeat, the time-indexed memory, and the proactive context injection — 800+ lines each — and would still cost LLM tokens because their safety verification is prompt-based.
+
+The structural principle generalizes: Passepartout's infrastructure investments compound. Each new subsystem (Merkle memory, heartbeat, skill engine, embedding pipeline) lowers the cost of the next feature. Time awareness is the first demonstration of this compounding — three layers unlocked by infrastructure already built for other purposes.
+
 ** Tiered Pricing: Cheap Models for Simple Tasks, Free for Learned Patterns
 
 The model-tier router (v0.3.0) classifies every task by complexity and routes it to the cheapest capable model. Simple lookups go to tiny local models or deterministic hash table scans (0 LLM tokens). Text processing goes to mid-tier models. Complex planning and code generation go to the premium model. The consensus loop (v0.10.0) only fires for high-impact actions.

 *** Token Economics (foundation complete — now build features)
 
 **Design insight: why token economics is the structural differentiator.** Passepartout's sparse-tree rendering and deterministic safety gates should produce 2–3x fewer tokens than competitors for equivalent coding tasks, and 13–24x fewer for knowledge management. But without caching and budget enforcement, the fixed overhead per call eats these savings. A coding session that touches 30 files with competent context management costs ~72K tokens (Passepartout) versus ~185K (Claude Code). Without caching, the Passepartout number climbs toward ~150K because every call retransmits the static prefix. The architectural advantage exists in theory but requires operational plumbing to materialize.

 The minimum viable local model advantage is structural: at 2,000–4,000 effective tokens (foveal-peripheral + caching), a 7–8B parameter model on consumer hardware is a daily driver. Competitors at 32K+ effective tokens require 70B+ parameter models and 16–32 GB VRAM. Passepartout runs on a laptop GPU where competitors need a data center card or cloud API.

 ** v0.6.0: Signal Pipeline, Concurrency & Streaming
 
 The current pipeline is strictly sequential — one signal traverses Perceive → Reason → Act before the next signal begins. Background tasks (heartbeat, embedding cron, gardener scans) compete with foreground interactions. A heartbeat that fires during a long tool chain is queued. A Telegram message during a multi-step planning cycle is queued. The system feels sluggish under concurrent load even though the symbolic operations are near-instant (SBCL hash table lookups are microseconds) — the bottleneck is the single-pipeline architecture, not the hardware.

-* 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.

-* 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~.

-#+AUTHOR: Agent
-#+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~.

-#+AUTHOR: Agent

-#+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)

-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
-

-#+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*
-
-The cascade for ~:code~ tasks (code generation, refactoring, bug fixing).

-
-* 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.

-(unbalanced parentheses). Other error types return a diagnosis without
