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. RewriteContext Context passed to a history rewriter.

SessionAppendNode Plugin-owned payloads carried on a SessionCreateRequest. SessionParam SessionPluginSource SessionRelation SessionStartPoint AssistantProseProjectorPlugin CodeExecutorPlugin HistoryRewriter Performs a permanent transform on persisted history (compaction,
overflow recovery, manual /compact, …). PluginAction PluginFactory Registers a plugin with the runtime and produces a per-session
SessionPlugin instance for each new session. ProtocolDriverPlugin Singleton plugin slot that owns the ProtocolDriverHandle and
associated preamble (prompt text, tool surface, sync/async flag)
for this session. Plugin stack construction must install exactly one
implementation. 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.
