A repo with a sealed key in .gstack/pregate.json (base branch union the
pushed commit, so a push can tighten but never relax) refuses publishing
sealed paths, transcripts, quoted answers, seeds or local home paths to a
public or unknown destination (SEALED_OUTPUT_REFUSED); private warns.
Path rules see every added, renamed or copied path in each published
commit (git rev-list <local> --not --remotes=<remote>), text rules each
commit's added lines; waivers only from the base branch allow file; a
malformed policy fails closed; visibility caches public 24 h, private 1 h.
