// ── tests/test_bell_safety.el ─────────────────────────────────────────────────
//
// Unit tests for the Hard Bell safety layer added in feat/connectors-soul.
// Covers the public API exposed by safety.el:
//   - safety_detect_bell_level:  'none' / 'soft' / 'hard'
//   - safety_classify_hard_bell: 'self_harm' / 'abuse'
//   - safety_normalize:          smart-quote -> ASCII apostrophe normalisation
//   - safety_augment_system:     system prompt passthrough / augmentation
//   - handle_safety_contact_post: validation + read-back
//
// El test convention: mutable pass_count / fail_count globals, assert_* helpers,
// println for each result.  Mirrors the style in existing safety tests.
