Let's use SL_CRITICAL. It flushes all collected buffers after add log message

if constexpr (false) would be better - selective compilation with checking both branches.

No, if constexpr (false) doesn't compile here (requires template).
std::chrono::seconds wait{1};
[&](auto &io) {
boost::system::error_code ec;
auto wait_us = std::chrono::duration_cast<std::chrono::microseconds>(wait);
if constexpr (requires { io->impl_.wait_one(wait_us.count(), ec); }) {
io->impl_.wait_one(wait_us.count(), ec);
ping();
io->poll_one();
} else {
io->run_one_for(wait);
}
}(io);

Description of the Change
An implementation of in-process watchdog based on timing out boost asio loops.
Default timeout is set to be 15 min.
Benefits
Not an over-complicated implementation.
Possible Drawbacks
The watchdog would not track the whole process state.
