autoUpgrade was silently failing daily on both hosts (legacy channel path,
no --flake set) without reaching the network — disabled outright since
rebuilds should only happen manually. Separately, nix-gc.timer's nightly
sweep was deleting eval-time-only flake input sources (not part of the
runtime closure), forcing the next evaluation to cold-refetch hermes-agent's
entire dependency tree from GitHub in one burst, which alone was enough to
hit the unauthenticated codeload rate limit. keep-outputs/keep-derivations
stop GC from evicting those sources.
