Handle orphan Chapter.novelId values before the table copy.
initializeDatabase enables foreign-key enforcement before calling the migrate function from drizzle-orm/op-sqlite/migrator. The OP-SQLite migrator runs migration statements in a transaction, and SQLite ignores PRAGMA foreign_keys=OFF inside that transaction. Therefore, the INSERT ... SELECT at line 32 enforces the new foreign key. If any existing Chapter row has no matching Novel, the migration can fail with FOREIGN KEY constraint failed, preventing startup.
Add explicit orphan-row repair or retention handling before the copy. Do not delete rows unconditionally without an approved data-retention policy.

Reject ZIP entries that resolve outside distDirPath (zip slip).
This PR touches the extraction path, but the unchecked entry names already existed before it. unzip and remoteUnzip build File(distDirPath, zipEntry.name) without checking the name. ensureParentDirectory then creates whatever parent directories the entry needs. The user chooses the restore archive, or it comes from a remote host. An entry such as ../../Plugins/x/index.js can therefore overwrite app files, including plugin code that the app later runs.
Check that each canonical output path stays inside the canonical destination.
Proposed fix
private fun resolveZipEntry(distDirPath: String, entryName: String): File {
val root = File(distDirPath).canonicalFile
val target = File(root, entryName).canonicalFile
require(target.path == root.path || target.path.startsWith(root.path + File.separator)) {

Flush reactive queries after executeBatch.
The old batch() path called flushPendingReactiveQueries() after executeBatch. The new batch() delegates to executeBatch(), which does not flush. write() still flushes on Line 141. As a result, insertChapters() and every restore write in NovelRestoreQueries.ts no longer notify reactive queries. The UI can show stale chapter lists and novel statistics until another write() runs.
Proposed fix
return await this.queue.enqueue({
id: 'write',

Insert parent Novel rows before inserting chapters.
Chapter.novelId now references Novel(id) in the test schema. createTestDb sets PRAGMA foreign_keys = ON. The raw inserts for novels 10 and 20 on Lines 191-199 now fail with FOREIGN KEY constraint failed. The unchanged test on Lines 158-170 fails for the same reason, because it uses orphan novelId = 123456. Its comment on Lines 156-157 is now wrong.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win
Make the encoder and the decoder accept the same records.
encodeNovelBatch writes records without validation. isCompactChapter rejects a chapter when its name (index 2) is empty. decodeNovelBatch then throws for the whole payload. getNovelFileRecordCount counts every novel in that file as failed. One chapter with an empty name therefore makes up to 100 novels in that batch file impossible to restore. The same applies to other field shapes that the database accepts but the decoder rejects.
Chapter.name is NOT NULL, but the schema allows ''. The codec already accepts an empty novel name because legacy data contains it. Apply the same rule to chapter names. Also validate each novel in prepareBackupData before encoding. Then an invalid novel counts as one backup failure instead of corrupting a batch.
Proposed fix
isId(value[0]) &&
nonEmptyString(value[1]) &&
- nonEmptyString(value[2]) &&
+ isString(value[2]) &&Apply the same change to normalizeLegacyChapter (!nonEmptyString(chapter.name) → !isString(chapter.name)).

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Call updateRestoreProgress directly.
setTimeout(..., 0) delays the validation progress update to a later macrotask. The loop keeps running meanwhile. A delayed "Validating novels (x/y)" text can therefore overwrite newer text, such as backupScreen.restoringNovels on Line 644. The timer serves no purpose. The code is also misformatted: the setTimeout call has no semicolon, and the if block's closing } is misplaced.
Proposed fix
if (index % 100 === 0) {
- setTimeout(async () => {
- updateRestoreProgress(
- setMeta,
- getString('backupScreen.validatingNovelsProgress', {
- current: index + 1,

- );
- }, 0)

Keep cover failures local to each novel.
When manifest.sections.downloadedFiles is false and a cover exists, a rejection from NativeFile.mkdir or NativeFile.copyFile rejects Promise.all before the batch mappings are recorded. This exits the novel-restore loop, so later novel files and batches are skipped. The database-restored novels in that batch are absent from novelIdMap, so their categories are omitted.
This does not prevent downloaded-file restoration. The cover-copy branch runs only when downloadedFiles is false, while downloaded files are restored only when that section is enabled. The base revision also caught cover failures per novel after recording each mapping.
Suggested fix
const coverBackupPath = coversDirPath + '/' + backupNovel.id;
- if (await NativeFile.exists(coverBackupPath)) {
- const coverPath = `${NOVEL_STORAGE}/${backupNovel.pluginId}/${novelMapping.restoredNovelId}/cover.png`;
- await NativeFile.mkdir(parentDirectory(coverPath));
