-## Primitives
+## Core concepts
 
-**`agent.Core`** — the central interface for a running agent session:
+**`session.Session`** — the public interface. A session is the runtime environment that hosts an agent. It provides identity, working directory, event bus, environment, and lifecycle management.
 
-- `Submit` — send a prompt, stream events via the bus
-- `Interrupt` — cancel the current turn
-- `Inject` — append a user interruption to the next tool result
-- `Queue`/`PopQueue` — buffered prompt FIFO
-- `Bus` — session event bus (pubsub)
-- `State` — current state: `idle`, `thinking`, or `calling: <tool>`
-- `Reply` — assistant text from the last completed turn
-- `WaitChange` — block until a field changes (state, usage, ctxsz, cwd)
-- `Detach`/`ListDetached`/`SignalDetached`/`GetDetachedOutput` — background process management
+**`session.Agent`** — the reasoning entity within a session. Owns the conversation history, LLM backend, tools, hooks, and system prompt. Swappable via `/agent` command.
 
-**`backend.Backend`** — the LLM interface: `ChatStream`, `Models`, `ContextLength`, `Name`, `Model`/`SetModel`, `DefaultModel`.
+**`session.harness`** (unexported) — implements Session. Wires the agent to the session environment and drives turn execution.
 
-**`tools.Server`** — interface for a tool provider: `ListTools`, `CallTool`. The primary implementation is `execute.Server` (local) with `execute.RemoteServer` for SSH-transparent execution.
+**`backend.Backend`** — the LLM interface: `ChatStream`, `Models`, `ContextLength`, `Name`, `Model`/`SetModel`.
 
-**`tools.Dispatcher`** — routes tool calls to the correct server by name. Built via `NewDispatcher` or `NewDispatcherFunc`.
+**`tools.Server`** — interface for a tool provider: `ListTools`, `CallTool`. Implementations: `execute.Server` (local) and `execute.RemoteServer` (SSH).
 
-**`tools.Registry`** — per-session dynamic tool loading. Discovers tool scripts from `OLLIE_TOOLS_PATH`, parses their schemas and metadata, and promotes them to native callable functions on demand.

 The 9P server (`olliesrv`) is the session manager. It instantiates the execute server, elevation broker, and tool/skill registries at daemon level. Sessions are created, queried, and controlled via the 9P filesystem — all agent interaction uses the `ollie-9p` client internally.
