  "changes": [
    "Added gated connection open, selected-command, EOF, per-subscription detach, and post-cleanup close markers in handle_conn.",
    "Added gated controller-install marker after the new ControllerSink is installed, classifying source, intent, and local/remote ownership without logging the `by` value or any frame/payload bytes.",
    "Made detach_if return an observation-only DetachDiagnostic while preserving controller/viewer removal and stamp behavior. Cleanup emits a detach marker for every my_subs entry, including already-reaped sessions.",
    "All new marker emissions are directly guarded by rca_pty_trace_enabled(), which is backed by SPT_RCA_PTY_TRACE=1."

  "signature_changes": [
    "OutputLog::become_controller now takes final `install: ControllerInstall`; spawn passes `ControllerInstall::Spawn`, subscribe resolution passes `ControllerInstall::Subscribe(intent)`.",
    "OutputLog::detach_if now returns `DetachDiagnostic { arc_matched, cleared }`; dispatch_unsubscribe intentionally discards it, while handle_conn cleanup logs it.",
    "Used the conn_id parameters already propagated through dispatch_spawn, dispatch_subscribe, resolve_subscribe, and controller_writer by the preceding RCA instrumentation work."
