All store images are now digest-pinned and cosign-signed by the publish pipeline, so the warn-by-default training-wheels period is over: an unsigned or undigested image must not install unless the admin explicitly opts out. The service_composer fallback used when the config manager is unavailable or corrupt also flips to enforce — config corruption must fail closed rather than silently weaken verification.
