controls
32-byte keys per message (AES-256-GCM); key rate is log₁₀ bit/s while the link is up. Starting buffer from
required_buffer_bytes at today's range. With the defaults, a two-week conjunction drains the capped buffer and the messenger refuses to send; switch on the relays and the refusals stop.
