That sounds stressful.

But perhaps Claude Code could detect that you're actively working on this stuff (like typing a prompt or accessing the files modified by the session), and send keep-cache-alive pings based on that? Presumably these pings could be pretty cheap, as the kv-cache wouldn't need to be loaded back into VRAM for this. If that would work reliably, cache expiry timeouts could be more aggressive (5 min instead of an hour).
