The greeter kf6 recipes were bumped to 6.28.0 (url/version/pin) but their committed source.tar is still 6.27.0 -- the version the greeter actually built against. Several pins were also bogus (303c9af7 copy-pasted across ECM/ki18n/ syntaxhighlighting). make-live re-fetch/validation failed: "downloaded tar blake3 ... is not equal to blake3 in recipe.toml" (kf6-extra-cmake-modules). Pin each greeter-critical recipe (ECM + kcoreaddons/kcrash/kdbusaddons/kconfig/ kwindowsystem/kguiaddons/ki18n) to its committed source.tar so offline builds validate against the real, working sources. ECM is genuinely 6.28.0; the rest 6.27.0. Build offline so the 6.28.0 URLs are not re-fetched. (Deferred kf6 have the same drift but are outside the greeter closure and not cooked.)
