Motivation

• Improve code coverage for CLI reporting helpers and artifact classification logic used by bundle inspection and audit summaries to reduce the risk of silent regressions.
• Exercise branch outcomes for formatter helpers and scanner-safe/runtime classification predicates so summary rendering and posture checks remain correct.

Description

• Add helper_formatters_cover_all_branches unit test to exercise yes_no_unknown, yes_no, and count_or_unknown branch behaviors in crates/uselesskey-cli/src/main.rs.
• Add artifact_material_classifiers_follow_scanner_posture unit test to validate bundle_artifact_contains_private_key_material and bundle_artifact_contains_symmetric_secret_material behavior across scanner-safe and runtime artifact states.
• Update test initializers to populate BundleArtifactRecord fields required by the struct (profile and lanes) used in the new tests, without changing production logic.

Testing

• Ran cargo test -p uselesskey-cli which executed the unit and integration test suite for the CLI package and completed successfully with all tests passing.
• New tests are included in the crates/uselesskey-cli/src/main.rs test module and were validated as part of the test run.
