Serialize replay reads with event appends, acquire the live receiver under that lock, and drain the event pump during shutdown. Recovery now removes its FIFO when opening the log fails.
Resume a stored ACP session through session/load and discard the history replayed during the load handshake so the durable event log remains the single transcript source.
New crate wrapping agent-client-protocol 2.1 in the client role. spawn()
resolves claude-code-acp on the PATH the child would run with, starts it
in the session cwd with the session env, runs initialize + session/new,
and returns an AcpSession holding the connection, the ACP session id,
and an unbounded channel of raw session/update notifications for #135.
initialize declares fs.readTextFile, fs.writeTextFile and terminal as
false so the adapter uses Claude Code's own tools. request_permission is
a stub that declines until #139.
terminate() sends session/cancel, waits, SIGTERMs, then SIGKILLs. The
child stays in the daemon's process group and gets SIGTERM on daemon
death via PR_SET_PDEATHSIG. CLAUDECODE is stripped from the child env:
the adapter refuses to start when it believes it is nested in another
Claude Code session, which is how a daemon launched from one behaves.
Tests run against tests/fake_acp_agent.py, a JSON-RPC-over-stdio stand-in
that logs what it receives; real_adapter_handshake is #[ignore]d.
