Internal refactor of artifact-publish permission checks and result assembly, no visible behavior change
The code behind publishing artifacts was reworked internally in two areas: the read-permission checks that guard against reading from under a symlinked or redirected base path, and the assembly of deploy results (warnings, embedded content, manifest and live file paths, and lists of newly-live or reseeded files). The visible messages, such as 'root: reading from under ... is blocked by a Read permission rule' and 'plus N file(s) copied server side from ...', are unchanged.
This appears to be a behind-the-scenes cleanup, largely variable renaming from code minification, rather than a change to how artifact publishing behaves or what you see.
