Publication provenance

This branch is a constructed public projection. Its commit trailers identify the internal source commit and the policy used to admit the projected tree. Admission means the tree is eligible for disclosure; it neither authorizes nor implies external publication.

.publication/paths.txt is the exact path authority. Every file in a candidate must be listed, and every listed file must exist. Parent directories grant no recursive authority. .publication/surface_gate.py can also write the exact mode, blob ID, size, and path inventory for one immutable candidate with --inventory-out.

Path authority covers every reachable commit, including files deleted before the tip. Removing a path from disclosure therefore requires history that does not contain it; a deletion commit alone is insufficient. Shallow history fails closed. Internal development history is preserved separately.

Reproduce the tree digest from a checked-out public commit with:

LC_ALL=C git ls-tree -r --full-tree HEAD^{tree} | LC_ALL=C sort | sha256sum

The result must equal the commit's Tree-Digest trailer.
