gstack-review-packet build --audit docs --candidate <snapshot> writes one packet:
the auditor prompt from the documentation section, the candidate's doc surfaces,
doc lines naming a changed code path, and the docs-plus-code diff. The reader
proposes edits as findings; gstack-docs-candidate apply makes each unique-match
edit outside protected and generated files and prints the audit result line the
section already validates. On Capy the section dispatches the packet reader;
other hosts keep the /document-release subagent.
