Узел drawio для агента был непрозрачен: round-trip хранит узел, но содержимое
диаграммы недоступно. Стадия 1 даёт минимальный CRUD без рендеринга на беке.
Новые модули:
- drawio-xml.ts: decode-chain (content= base64 -> plain/entity-encoded XML или
compressed <diagram> через pako.inflateRaw raw-deflate + decodeURIComponent;
инфляция потоковая с капом 16 MiB — защита от decompression-bomb); encode
(plain uncompressed по контракту createDrawioSvg); линтер (все правила ->
структурированный tool-error с cellId; edge без дочернего mxGeometry — ошибка
№1); stable mxHash (sha256 по нормализованному XML) — ключ optimistic-lock.
- drawio-preview.ts: чистый TS schematic SVG (rect/ellipse/rhombus/edge/label,
контейнеры -> абсолютные координаты, unknown-стенсил -> подписанный rect),
без зависимостей и без бэкенд-рендера.
Инструменты (SHARED_TOOL_SPECS, deferred-тир):
- drawio_get(pageId, node, format?) -> XML/SVG + мета {attachmentId,title,w,h,
cellCount,hash}; читает человеческий compressed-экспорт losslessly.
- drawio_create(pageId, where, xml, title?) -> lint -> preview -> .drawio.svg ->
upload (тот же attachment-конвейер + validateDocUrls) -> insert drawio-узел;
возвращает адресуемый '#<index>'-хендл (у схемы drawio нет атрибута id).
- drawio_update(pageId, node, xml, baseHash) -> baseHash-конфликт до записи;
перепривязывает РОВНО адресованный узел (не все с общим attachmentId).
pako@2.0.3 — единственная новая зависимость (lockfile синхронизирован).

// Unit tests for the pure-TS schematic SVG preview (issue #423). Asserts that
|
|
// the preview emits well-formed SVG covering each primitive (rect/ellipse/
|
|
// rhombus/edge), resolves container-relative coordinates to absolute, and that
|
|
// the full `.drawio.svg` wrapper parses.
