Module session 

Session actor surface (Phase 2 daemon mode).

One SessionActor (A1) owns THE Runtime + ConversationState for a conversation and runs its turn machine; clients talk to it through a ClientTransport — LocalTransport in-process (same StreamEvent values, never serialised = byte-identical), SocketTransport (B2) over the daemon UDS. agent-tui must never be a dependency of anything here.

Modules

actor

SessionActor — owns THE Runtime + ConversationState for one conversation and runs its turn machine (PLAN-phase2 §2.5).

actor_cmds

SessionActor — command bodies that belong to the TUI port (A3): engine_command (structured reply), submit_prepared, plugin_command, resume, session_name, emit_subagent_rows. Kept apart from actor.rs so the turn machine (B) and the command surface (A) never touch the same file.

budgets

Teardown budgets shared by every session host (values copied from agent-tui/src/tui/signals.rs; signals.rs re-exports these on day 2).

cache_keepwarm

Prompt-cache keep-warm policy (task #444), owned by the session actor.

client_args

Client-side resolution of path-like SessionConfig arguments (T4, F26).

display

Daemon-side display projection of api_messages (PLAN-phase4 §2.3).

driver

Actor-side session driver state machine (E §2).

handle

SessionHandle — the in-process address of a session (PLAN-phase2 §2.6).

socket_transport

SocketTransport — the client side of the daemon UDS (PLAN-phase2 §2.10).

transport

ClientTransport + LocalTransport (PLAN-phase2 §2.7).

types

Identity, configuration, commands, events and the envelope — the entire client↔session contract (PLAN-phase2 §2.1–§2.4). Everything a client can send is serde-able from day one; SessionEventWire::Stream deliberately is not (it carries the un-serialised StreamEvent in-process).

view

RuntimeView + RuntimeRead (PLAN-phase2 §2.8).

wire

Wire frames for the daemon UDS (PLAN-phase2 §2.9, S289 D-2 amended).
