<h4>DocSign Document Visibility Fix</h4><ul><li><strong>Fixed:</strong> Document not visible when viewing docs (e.g. docs=55) — a4/docs.php used inner_join on AuthorID to users table, but the author user (uid 207) was deleted. Inner join returned null result, extract(null) crashed, and the entire document was invisible. Changed to left_join so documents display even when the author user no longer exists.</li><li><strong>Fixed:</strong> Added null guards on extract($legalDocsData) in both a4/docs.php and legal_docs.php to prevent crashes when document data is null.</li><li><strong>Fixed:</strong> Added $signed_at ?? null fallback in a4/docs.php to prevent undefined variable warning.</li></ul>
