v1.0.5: syllableMode, heuristic-as-override, dead code cleanup

Added:
- Language::syllableMode (tex|heuristic|composite), default tex
- HeuristicSyllableCounter::hasWord() per-word lookup
- 39 new tests: HeuristicSyllableCounterTest, CompositeSyllableCounterTest

Changed:
- Heuristic complements TeX, not replaces it (composite mode)
- hasRules() checks only problemWords, not subtract/addPatterns
- CompositeSyllableCounter fallback delegates to last chain counter
- wordsWithNSyllables() renamed to wordsWithMoreThanNSyllables()

Fixed:
- Non-ASCII: [^a-z] to [^\p{L}]/u, all preg_* with /u flag
- WienerSachtextformel: throws on invalid variant (not 1-4)
- SzigrisztPazos: eliminated redundant *100/100

Removed:
- FormulaResult::gradeLabel (always null in 16/17 formulas)
- Engine::\ (local variable instead)
- Pattern::toString() (dead production code)

+## [1.0.5] - 2026-06-26
+
+### Added
+- `Language::syllableMode` — per-language syllable counting strategy (`tex`|`heuristic`|`composite`), default `tex`
+- `HeuristicSyllableCounter::hasWord()` — per-word lookup in problemWords
+- 39 new tests: `HeuristicSyllableCounterTest` (25), `CompositeSyllableCounterTest` (9), `LanguageTest` (+5)
+
+### Changed
+- **Heuristic now complements TeX, not replaces it**: `composite` mode uses heuristic only for explicit problemWords, falling through to TeX for everything else
+- `hasRules()` now checks only `problemWords` (not subtract/addPatterns) — allows TeX fallthrough for non-problem words
+- `CompositeSyllableCounter` fallback: `return 1` → delegates to last counter in chain
+
+### Fixed
+- **Non-ASCII support**: `[^a-z]` → `[^\p{L}]/u`, all `preg_*` calls now use `/u` flag — Cyrillic, German umlauts, accented characters correctly preserved
+- `WienerSachtextformel`: invalid variant numbers (0, 5+) now throw `\InvalidArgumentException` instead of silently computing variant 4
+- `SzigrisztPazos`: redundant `*100/100` eliminated, display value preserved in inputs
+
+### Removed
+- `FormulaResult::gradeLabel` — dead field, always `null` across 16 of 17 formulas (Lix duplicated `interpretation`)
+- `Engine::$languageRepository` — unused property (kept as local variable in constructor)
+- `Pattern::toString()` — dead production code
+- `wordsWithNSyllables()` → renamed to `wordsWithMoreThanNSyllables()` (name now matches behaviour: `> N`)
+
+### Data
+- `en-us.json`, `en-gb.json` — added `"syllableMode": "composite"`

+
+**Date:** 2026-06-26  
+**Scope:** `src/` (48 files), `tests/` (18 files), root config  
+**Verification:** PHPStan level max (0 errors), PHPUnit (262 tests, 1034 assertions — green)

+## All findings (10)
+
+| # | Severity | File(s) | Description | Status |
+|---|----------|---------|-------------|--------|
+| C1 | CRITICAL | `HeuristicSyllableCounter`, `CompositeSyllableCounter`, `Engine` | Heuristic полностью подавляет TeX для английского — `hasRules()` возвращал true из-за subtract/addPatterns, Composite никогда не доходил до TeX | ✓ fixed |
+| M1 | MEDIUM | `HeuristicSyllableCounter.php:71` | `preg_replace('/[^a-z]/', ...)` вырезал все не-ASCII символы; `preg_split`/`preg_match` без флага `/u` ломали UTF-8 | ✓ fixed |
+| M2 | MEDIUM | `TextAnalyzer.php:96`, `Engine.php:179` | `wordsWithNSyllables()` считает слова с **>N** слогов, называется «с N слогами» | ✓ fixed |
+| L1 | LOW | `FormulaResult.php:16` | `gradeLabel` всегда `null` (кроме Lix, где дублирует `interpretation`) | ✓ fixed |
+| L2 | LOW | `Engine.php:35` | `$languageRepository` присвоен в конструкторе, нигде больше не прочитан | ✓ fixed |
+| L3 | LOW | `Pattern.php:22` | `toString()` никогда не вызывается в production | ✓ fixed |
+| L4 | LOW | `WienerSachtextformel.php:45-55` | variant=5 молча считается как variant=4 | ✓ fixed |
+| L5 | LOW | `CompositeSyllableCounter.php:25` | Fallback `return 1` | ✓ fixed |
+| I1 | INFO | `SzigrisztPazos.php:38-40` | `$S = x * 100.0; ... $S / 100.0` — избыточное умножение/деление | ✓ fixed |
+| I2 | INFO | `HeuristicSyllableCounter.php:137` | `splitSyllables` делит строку арифметически, не лингвистически | ✓ fixed |
+
+---
+
+## Fixed (10) — все исправлено
+
+### Раунд 1 — Heuristic + TeX архитектура (C1, M1, L5)
+
+**Проблема:** `HeuristicSyllableCounter` полностью заменял TeX для английского, не дополнял.
+
+**Решение:**
+- `HeuristicSyllableCounter::hasRules()` → теперь только `problemWords !== []`
+- Добавлен `hasWord(string)` — проверка конкретного слова
+- `CompositeSyllableCounter` — `countSyllables`/`splitSyllables` используют `hasWord()` вместо `hasRules()`: problemWord → heuristic, остальное → TeX
+- `Language` — новое поле `syllableMode` (`tex`|`heuristic`|`composite`), дефолт `tex`
+- `Engine::loadSyllableCounter` — диспетчеризация по `syllableMode`
+- `[^a-z]` → `[^\p{L}]/u`, все `preg_*` получили флаг `/u`
+- `en-us.json`, `en-gb.json` → `"syllableMode": "composite"`
+- +39 тестов (`HeuristicSyllableCounterTest`, `CompositeSyllableCounterTest`, `LanguageTest`)
+
+### M2 + L2 + L3 + L4 — чистка (раунд 2)
+
+- **M2** — `wordsWithNSyllables` → `wordsWithMoreThanNSyllables` в `TextAnalyzer` + `Engine`
+- **L2** — удалён `$languageRepository` из Engine (локальная переменная вместо свойства)
+- **L3** — удалён `Pattern::toString()` + тесты к нему
+- **L4** — `WienerSachtextformel`: variant вне [1,4] → `\InvalidArgumentException`
+
+### Раунд 3 — добивка (L1, I1, I2)
+
+- **L1** — удалён `gradeLabel` из `FormulaResult` (17 формул + тест)
+- **I1** — `SzigrisztPazos`: устранено `*100/100`, промежуточное значение `syllablesPer100` сохранено для inputs
+- **I2** — `HeuristicSyllableCounter::splitSyllables`: добавлен doc-комментарий с описанием ограничения
