From 09d35da0a4cdee382bf3c8cebc9a79296da6eb9f Mon Sep 17 00:00:00 2001 From: jedarden Date: Sun, 5 Jul 2026 16:08:34 -0400 Subject: [PATCH] docs(bf-2nl4x): verify encryption test infrastructure completion All necessary imports and test infrastructure are already in place: - Standard library imports (fs, path, process) - pdftract CLI imports (exit codes) - pdftract Core imports (diagnostics, decryption errors) - Test helpers (pdftract_bin, encrypted_fixture, assertion functions) - Test modules (unsupported_handlers, exit_codes, password_handling, consistency) File compiles successfully and all imports match actual crate structure. Infrastructure was implemented in previous commit as part of bf-5for4.
