+# SHiNE ANS-104 `test5590` patch
+
+Этот архив содержит **только новые/изменённые файлы** плюс `DELETE_FILES.txt`.
+
+## Что меняется
+
+- Frame v1 без поддержки старого формата.
+- Один пользовательский block = готовый Ed25519 ANS-104 DataItem.
+- Test tag: `App=test5590`; channel tag: `c=<canonical slug>`.
+- SHiNE `prevHash` остаётся `SHA-256(FrameV1Bytes)` и не зависит от Arweave ID.
+- PostgreSQL — единственное локальное хранилище пользовательских blocks.
+- Старый custom SHINE-ARCHIVE и filesystem blockchain storage удаляются.
+- Каждые ~15 минут локальные pending DataItems собираются в standard ANS-104 bundle и идут через существующий native Arweave L1 transport.
+- Другие серверы находят `App=test5590`, импортируют и не публикуют повторно.
+- `ESP32/**` **не изменён**.
+
+## Состав
+
+- изменено/добавлено файлов: 46
+- удалить файлов: 41
+
+Применение и проверки: `docs/Blockchain/CODEX_APPLY_ANS104_TEST5590_PATCH.md`.
+
+## Проверки при сборке patch
+
+- `node --check` для изменённых production JS: OK.
+- `diff -qr` каталога `ESP32` относительно исходного архива: без изменений.
+- Active Java refs на удалённые SHINE-ARCHIVE/file-recovery classes: отсутствуют.
+- `./gradlew testClasses --offline --no-daemon`: не запущен до компиляции, потому что wrapper требует скачать Gradle 8.14 с `services.gradle.org`, а рабочая среда не имеет внешнего сетевого доступа. Полный Gradle test обязателен после применения patch в dev-среде.

- *
- * hash32 НЕ хранится в блоке.
- * hash32 вычисляется при парсинге:
- *   preimage = первые blockSize байт
- *   hash32   = SHA-256(preimage)
- *
- * Правила MVP-парсера (Frame v0):
- *  - frameCode должен быть строго 0x0000, иначе REJECT.
- *  - sigMarker должен быть строго 0x0100, иначе REJECT.
- *  - подпись обязана присутствовать всегда (sigMarker+signature64).
- *  - НИКАКИХ fallback-веток “если маркер другой, то подписи нет/другой хвост”.
- *
- * Важно по безопасности:
- *  - sigMarker в v0 не входит в подписываемые байты → его можно подменить,
- *    поэтому единственная безопасная логика: "если не 0x0100 — reject".
- * =========================================================================
+ * The user signature is NOT stored in this frame. It is the single Ed25519/Solana
+ * signature of the surrounding ANS-104 DataItem.
