configuring the runtime from a fresh SessionCreateRequest. ProtocolSessionContext Narrow wrapper around Session that protocol plugins use to
initialize, restore, and extend their per-session state. ProtocolSessionMaterialization Read-only descriptor of a session materialization handed to

Membership is the
execution gate, so the only override a contribution can express is removal
of a member (authority hiding, plan-mode gating). Adding members happens by
a [crate::ToolProvider] including them in its manifest list.

PluginCommand PluginFactory Registers a plugin with the runtime and produces a per-session
SessionPlugin instance for each new session. PluginOperation PluginQuery PluginTask ProcessReadService ProtocolDriverPlugin Singleton kernel extension slot that owns the ProtocolDriverHandle and
associated preamble (prompt text, tool catalog, sync/async flag) for this
session. ProtocolSessionPlugin Session-scoped plugin that initializes, restores, and extends protocol
state across a session’s lifecycle. External protocol crates implement
this via context wrappers (ProtocolSessionContextProtocolRuntimeContextSession/LashRuntime internals — the context narrows what a
plugin can poke at to the capabilities any protocol reasonably needs.
