- OpenBucket validates public_url (absolute http/https, host, no user info, query
or fragment; the error names the key) and records it next to public_path_prefix
- a set public_url logs one start-up line: the bucket behind it must hold only
public files, since it bypasses the is_public check
- attach.PublicURLBase; PublicURL, File.URL and thumbnail URLs use the base when
set and keep the public_path_prefix proxy URLs otherwise
- TestPublicURLSmoke; storage Public URL base section, attachments, configuration
and lagoon README
- Manifest.Tags from build.tags (^[a-z0-9_]+$, duplicates dropped), round-tripped by SaveManifest
- summer build passes -tags=<list> through goBuildArgs and prints the build tags line
- attach: s3blob imported only by s3_on.go (//go:build summercms_s3); an untagged binary
refuses an s3:// bucket_url naming the tag, build.tags and -tags
- go mod tidy adds the AWS SDK v2 modules as indirect requirements
- storage, modules, scaffolding, configuration and scaling docs plus the lagoon README
