- Add DEFAULT_THRESHOLDS['drop'] = -5 and DEFAULT_HARD_DROP_RULES const
- Add evaluate_hard_drop(): fires when no positive signals + short latin name OR ≥3 placeholder fields
- Wire into classify(): drop overrides all other labels; synthetic reason explains trigger
- Add drop_reason_label() and 'drop' => '⛔ авто-дроп' to MessageFormatter::LABEL_MAP
- Update ClassifierTest/MessageFormatterTest to extend Cf7stgTestCase (filter isolation)
- Adjust pre-existing assertions that now correctly yield 'drop' instead of 'spam'
Fixes issues from code review in commit 249f195:
1. Tighten fixture assertions to exact counts (assertSame instead of assertGreaterThanOrEqual):
- test_count_placeholder_fields_screenshot_1_exact_count: expect 5 placeholders
- test_count_placeholder_fields_screenshot_2_exact_count: expect 5 placeholders
- test_count_placeholder_fields_screenshot_3_exact_count: expect 1 placeholder
2. Document SERVICE_FIELD_KEYS prefix-matching semantics in comment:
clarify that keys starting with _wpcf7 are skipped via strpos prefix match,
so explicit enumeration of every _wpcf7_* variant is unnecessary.
Test results: 75/75 green.
