Mind::init() now handles channel daemons, observation socket, and
scoring startup. event_loop::run() creates its own idle state and
channel polling — UI concerns owned by the UI.
Startup run() is now: create agent, create Mind, init, spawn Mind,
run event_loop. Seven parameters on event_loop::run() instead of
twelve.
Remove observe_input_rx from event loop (being replaced by channel).

Mind::init() restores conversation from log and starts scoring.
No UiMessages sent. The UI event loop reads Mind's state after
init and displays startup info (model, restored conversation)
by reading the agent directly.
mind/mod.rs has zero UiMessage imports or sends. Complete
separation between cognitive state machine and user interface.

UserInput display moved to UI diff — when MindState.input goes from
populated to empty (consumed by a turn), the UI displays it. Mind
no longer sends any UiMessage from its event loop.
Remaining UiMessages are only in the startup function (one-time
init info).

dmn_sleep/dmn_wake/dmn_pause/cycle_autonomy were just setting two
fields each. Inline the assignments at call sites. cycle_autonomy
moves to event_loop since it's UI state machine logic (deciding
which label to show).

Compaction is CPU-only on in-memory data — no reason to spawn a
task. Inline it in run_commands as a synchronous agent lock + compact.
Co-Authored-By: Kent Overstreet <kent.overstreet@linux.dev>
CycleAutonomy just flips DMN state — handled directly in event_loop
by locking shared MindState. MindCommand::Hotkey replaced with
MindCommand::Interrupt — the only command that needs Mind's async
context (abort handles, kill processes).
Remove dmn_interval() wrapper — inline self.dmn.interval().
MindCommand is now: Turn, Compact, Score, Interrupt, NewSession, None.

These were called from handle_turn_result before the refactor but
got lost during the MindState migration. Re-add them in the turn
completion path. Delete the trivial refresh_context_state wrapper.

MindCommand replaces both Action and MindMessage — one type for
everything: turns, compaction, scoring, hotkeys, new session.
State methods return MindCommand values. The run loop collects
commands into a Vec, then drains them through run_commands().
Compact and Score now flow through the same command path as
everything else.
Removes execute(), MindMessage from event_loop. Mind's run loop
is now: select! → collect commands → run_commands().
mind/mod.rs: 957 → 516 lines.

UI event loop clones MindState on each render tick, diffs against
the previous copy, and generates status updates from changes. Mind
no longer sends UiMessage::StatusUpdate — state changes are detected
automatically by the UI.
Removes update_status from both Mind and event_loop. DMN state
changes, turn tracking, scoring status all flow through the diff.
Zero UiMessage sends from Mind's run loop for state changes.

Both are pure UI operations that read config/shared state and format
display messages. No Mind state mutation involved.

/dmn, /sleep, /wake, /pause now lock MindState directly from the
UI event loop. No MindMessage roundtrip needed — they're just
state transitions + info display.
MindMessage reduced to: Hotkey (Interrupt, CycleAutonomy),
NewSession, Score. Everything else handled directly by UI.

MindState (behind Arc<Mutex<>>) holds all cognitive state: DMN,
turn tracking, pending input, scoring, error counters. Pure state
transition methods (take_pending_input, complete_turn, dmn_tick)
return Action values instead of directly spawning turns.
Mind is now just the event loop: lock MindState, call state methods,
execute returned actions (spawn turns, send UiMessages). No state
of its own except agent handle, turn handle, and watch channel.
mind/mod.rs: 957 → 586 lines.

Add MindState behind Arc<Mutex<>> for state shared between Mind
and UI. Pending user input goes through shared state instead of
MindMessage::UserInput — UI pushes, Mind consumes.
Mind checks for pending input after every event (message received,
turn completed, DMN tick). User input is prioritized over DMN ticks.
This enables the UI to display/edit/cancel queued messages, and
removes the last MindMessage variant that carried data.

cycle_reasoning, kill_processes, and AdjustSampling only need the
Agent lock — they're pure Agent operations. Handle them directly
in the UI event loop instead of routing through Mind.
Mind now only receives Interrupt and CycleAutonomy as hotkeys,
which genuinely need Mind state (turn handles, DMN state).
mind/mod.rs: 957 → 688 lines across the session.

All slash command routing now lives in user/event_loop.rs. Mind
receives typed messages (NewSession, Score, DmnSleep, etc.) and
handles them as named methods. No more handle_command() dispatch
table or Command enum.
Commands that only need Agent state (/model, /retry) run directly
in the UI task. Commands that need Mind state (/new, /score, /dmn,
/sleep, /wake, /pause) send a MindMessage.
Mind is now purely: turn lifecycle, DMN state machine, and the
named handlers for each message type.

Add tokio::sync::watch for turn_in_progress state. Commands in the
UI event loop can wait for turns to complete via wait_for() instead
of checking-and-bailing.
Move /retry to event_loop: waits for turn completion, pops agent
history, sends retried text as MindMessage::UserInput. Mind doesn't
need to know about retry — it just sees a new input message.
Make agent field pub on Mind for UI access.

/quit, /help, /save handled directly in the UI event loop.
/model and /model <name> moved to event_loop as cmd_switch_model().
Mind no longer needs tui::App for any command handling.
Mind's handle_command now only has commands that genuinely need
Mind state: /new, /retry, /score (turn_in_progress, DMN, scoring).

Mind::run() owns the cognitive event loop: user input, turn results,
DMN ticks, hotkey actions. The UI event loop (user/event_loop.rs) owns
the terminal: key events, render ticks, channel status display.
They communicate through channels: UI sends MindMessage (user input,
hotkey actions) to Mind. Mind sends UiMessage (status, info) to UI.
UI reads shared state (active tools, context) directly for rendering.
Removes direct coupling between Mind and App:
- cycle_reasoning no longer takes &mut App
- AdjustSampling updates agent only, UI reads from shared state
- /quit handled by UI directly, not routed through Mind

The cognitive state machine is a Mind, not a Session. This is the
struct that AgentCycle will hang off of when we add subagent forking.

Memory scoring now uses the graph as source of truth:
- last_scored timestamp on each node (new capnp field @22)
- Nodes scored when older than scoring_interval_secs (default 1hr)
- Oldest-scored-first ordering
- Window: scoring_response_window assistant responses (default 100)
- First-quarter memories scored even without full window
- Per-response normalization (raw divergence / response count)
- Asymmetric weight update: alpha=0.5 up, alpha=0.1 down
(responds fast to importance, decays slowly — memories stay
surfaced even if only useful 1/4 of the time)
Graph writes disabled pending normalization calibration.
Also: configurable scoring_interval_secs and scoring_response_window.

Reject tool calls with malformed JSON arguments early, returning
a clear error to the model instead of silently defaulting to null
and dispatching anyway. Prevents cascading failures when the model
generates truncated tool call arguments.

Disables memory scoring, surface, and observe agents when set.
Useful for testing with external backends (e.g. OpenRouter) where
background agent traffic would be slow and unnecessary.

consciousness-channel-socat listens on a unix socket for incoming
connections, turning each into a bidirectional text channel. Also
supports outbound connections via the open RPC (tcp: or unix:).
Two sockets:
socat.sock — capnp RPC (channel protocol)
socat.stream.sock — data (incoming connections become channels)
No config file needed. The simplest possible channel daemon.

find_daemon() replaces daemon_sock() — walks the dot-delimited channel
path from most-specific to least looking for a daemon socket, and
auto-starts via the supervisor if none is found. All channel tools
(recv, send, open, close) use the same resolution path.
Fix tmux daemon to use pane_id consistently for both pipe-pane and
send-keys (send-keys -t <label> doesn't work, needs the %N pane id).
Store label→pane_id mapping in State instead of bare label vec.
Gracefully handle missing tmux.json5 — start with empty pane list
since panes are added dynamically via the open RPC.
Co-Authored-By: Proof of Concept <poc@bcachefs.org>
Add open/close to the channel capnp schema. The tmux daemon implements
open by finding a pane by name (pane title or window name) and
attaching pipe-pane; close detaches and removes from state.
Tool handlers channel_open and channel_close added to the tool
registry.

Move the entire stream event processing loop (content accumulation,
leaked tool call detection/dispatch, ToolCallDelta assembly, UI
forwarding, display buffering) into api::collect_stream(). The turn
loop now calls collect_stream() and processes the StreamResult.
Also move FunctionCall, ToolCall, ToolCallDelta to api/types.rs where
they belong (API wire format, not tool definitions). Move parsing.rs
to api/parsing.rs.

run_one_agent is meant to run within a long-running process (daemon,

journal_tools() was only in memory_and_journal_tools() for
subconscious agents — not in the main tools() registry. Added

dispatch_shared was a legacy wrapper — replaced by dispatch() which
goes through the unified Tool registry. One dispatch path for all
callers (interactive agent, subconscious agents, MCP server).

ToolDef and FunctionDef are gone. Tool definitions are static strings
on the Tool struct. The API layer builds JSON from Tool::to_json().
- ChatRequest.tools is now Option<serde_json::Value>
- start_stream takes &[Tool] instead of Option<&[ToolDef]>
- openai::stream_events takes &serde_json::Value for tools
- memory_and_journal_tools() returns Vec<Tool> for subconscious agents
- Subconscious agents filter by t.name instead of t.function.name
No more runtime JSON construction for tool definitions.
No more ToolDef::new(). No more FunctionDef.

Tool derives Copy (all fields are Copy: &'static str + fn pointer).
dispatch_with_agent copies the Tool out of the agent lock guard,
drops the guard, then calls the handler. No Arc cloning needed.

working_stack now uses the Tool format with an Agent handle —
it locks the agent and modifies the stack directly. The special-case
interception in the turn loop is removed. All tools go through
the unified registry dispatch.
Also passes agent handle to all spawned tool tasks so any tool
that needs Agent access can use it.

Control tools (pause, switch_model, yield_to_user) now use the
Arc<Mutex<Agent>> handle to set pending_yield, pending_model_switch,
pending_dmn_pause directly. The turn loop drains these flags into
TurnResult at completion.
ToolOutput simplified to just { text: String } — no more is_yield,
images, model_switch, dmn_pause fields. Vision returns plain strings.

Tool definitions are now &'static str (name, description,
parameters_json) instead of runtime-constructed serde_json::Value.
No more json!() macro, no more ToolDef::new() for tool definitions.
The JSON schema strings are written directly as string literals.
When sent to the API, they can be interpolated without
serialization/deserialization.
Multi-tool modules return fixed-size arrays instead of Vecs:
- memory: [Tool; 12], journal: [Tool; 3]
- channels: [Tool; 4]
- control: [Tool; 3]
- web: [Tool; 2]
ToolDef/FunctionDef remain for backward compat (API wire format,
summarize_args) but are no longer used in tool definitions.
