 # ── Async RPC dispatch (#12546) ──────────────────────────────────────
 # A handful of handlers block the dispatcher loop in entry.py for seconds
 # to minutes (slash.exec, cli.exec, shell.exec, session.resume,
-# session.branch). While they're running, inbound RPCs — notably
-# approval.respond and session.interrupt — sit unread in the stdin pipe.
-# We route only those slow handlers onto a small thread pool; everything
-# else stays on the main thread so ordering stays sane for the fast path.
-# write_json is already _stdout_lock-guarded, so concurrent response
-# writes are safe.
