<li><code>internal/mailconv/handlers.go</code> — <code>pdfHandler</code> сейчас = <code>ocr.PDFFile</code>.
Гибрид встаёт рядом: <code>pdfHandler → docpipe.Handle</code> (fast path отдаёт тот же
pdftotext-текст, что и сегодня), liteparse-ветка — только по требованию
(скан/структура), чтобы не добавить 120 ms каждому PDF-вложению.</li>
<li><code>internal/etl</code> Registry (<code>#96</code>) — handler по MIME; docpipe — кандидат на
обработчик <code>application/pdf</code>, где <code>Result</code> → typed <code>Meta</code> + <code>Text</code> +
lazy-<code>Children</code>, а <code>Tables</code> — гранулярные Item-узлы (#100): каждая ячейка —
узел с URL и <code>sha256</code> контента, ссылки между частями только по URL.</li>
<li>Разделение ответственности: <code>internal/ocr</code> (tesseract/gs-нормализация)
остаётся как fallback для экспорт-защищённых PDF; docpipe — структурный
путь. Решение о замене <code>ocr.PDFFile</code> — позже, за рамками PoC (#223).</li>

<p dir="auto"><strong>Handler готов к интеграции</strong> в mailconv/etl как опциональный структурный
путь: офлайн-тесты зелёные (<code>go test -race ./internal/docpipe/...</code>), live-прогон
распознаёт таблицу синтетического счёта через тёплый сервис, метрики в
ожидаемых рамках (#221: ~7-10 ms fast, ~110-130 ms warm liteparse). Ограничения
PoC: ячейка = один <code>text_item</code> (без склейки разорванных), порог — половина
медианного font_size (без адаптации к многошрифтовым страницам), выбор пути
не автоматизирован через вердикт (нужен аккуратный порог по #221-выводам).
Следующие шаги эпика #219: склейка разорванных items, прогон по реальному
корпусу, интеграция docpipe в etl registry.</p>
