#  - GOSUMDB=off: verify module hashes against the committed go.sum ONLY, not
#    sum.golang.org. Some first-party modules are freshly published or were
#    re-tagged, so the public sumdb lags; go.sum is the source of truth.
#  - Everything else uses the default proxy (proxy.golang.org,direct): public
#    modules the proxy has cached resolve there; a proxy miss falls back to
#    direct git (public tag exists) — NOT forced direct (which broke on
#    luxfi/geth, whose proxy-cached version has no live git tag).
