Merge Risk: 🔵 Low · up to 85938

The PR adds settings-profile synchronization. A success-path test may pass before synchronization finishes or persistence is confirmed, which could let regressions go undetected; the change is otherwise mergeable with owner awareness, and the unrelated locale entry should be split into a separate PR.

240-249: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

forceCloudBackup / forceCloudSync にエラーハンドリングがありません。

forceCloudSync(および同じパターンを持つ forceCloudBackup)は cloudBackup() / cloudSync()try/catch なしで呼び出しています。これらの関数がエラーを投げた場合(例えば、manager.tsmergeProfiles に関するコメントで挙げたスキーマ不一致によるクラッシュや、通信エラー)、os.success() が呼ばれないだけで、ユーザーには失敗したことが一切通知されません。

PreferencesManager.enableSync() では同様のクラウド操作の失敗時に os.alert でエラーを通知するパターンが既にあります。同様のエラーハンドリングをこの2つの関数にも追加することをおすすめします。

🛡️ 修正案
 async function forceCloudSync() {
-	await cloudSync();
-	os.success();
+	try {
+		await cloudSync();
+		os.success();
+	} catch (err) {
+		os.alert({
+			type: 'error',
+			title: i18n.ts.somethingHappened,

550-572: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

enableSynccommit() の戻り値が実際には使われていません。

Line 550 で commitedRecord を受け取っていますが、以降の Line 555 の cloudSet 呼び出しと Line 571 の record[2].sync = true は、いずれも Line 539 で取得した古い record をそのまま使い続けています。

この実装には2つの問題があります。

1つ目は、対象キーがアカウント依存・サーバー依存の設定で、まだアカウント・サーバー固有のスコープを持っていない場合です。この場合 commit()(Line 296-317)は新しいスコープのレコードを作成して返しますが、record は古い(より汎用的な)スコープのレコードのままです。そのため cloudSet は誤ったスコープと古い modifiedAt を送信し、Line 571 の record[2].sync = true も実際に値を保持している新しいレコードではなく、古いレコードに設定されてしまいます。結果として、UI 上は同期が有効に見えても、実際にはその後の commit() が正しいレコードの sync フラグを見つけられず、同期が機能しなくなります。

2つ目は、newValue が現在値と同じ場合です。この場合 commit()deepEqual により null を返す(Line 285-288)ため modifiedAt は更新されず、古い値または undefined のまま cloudSet に送られます。今後の mergeProfiles による比較で、このレコードは常に他の値に負けてしまう可能性があります。

commitedRecord を実際に使用するよう修正することをご検討ください。

🐛 修正案
-		const commitedRecord = this.commit(key, newValue);
+		const commitedRecord = this.commit(key, newValue) ?? this.getMatchedRecordOf(key);

 		const done = os.waiting();

 		try {
-			await this.io.cloudSet({ key, scope: record[0], value: newValue, meta: { modifiedAt: record[2].modifiedAt } });
+			await this.io.cloudSet({ key, scope: commitedRecord[0], value: newValue, meta: { modifiedAt: commitedRecord[2].modifiedAt ?? Date.now() } });
 		} catch (err) {
 			...
 		}

 		done({ success: true });

-		record[2].sync = true;
+		commitedRecord[2].sync = true;
 		this.save();

cloudBackupcloudRead/cloudSet 経由で同期値を消さないよう分岐してください。

cloudBackup() はバックアップキーを取得・マージして i/registry/set で保存しますが、ここから cloudSet() を呼ぶと同じキーの client.preferences.sync 配列全体が新規の更新対象で上書きされます。同期フラグ付き設定値や既存の sync スコープ値を消さないよう、cloudSet() の対象を同步設定の更新のみに絞るか、同期値を合成して書き戻す実装にしてください。

cloudSet() 自体も i/registry/get → 配列更新 → i/registry/set の非アトミックな read-modify-write なので、別のタブ・デバイスで同じキーの別スコープが更新されると後発の書き込みで先発の更新分を失う可能性があります。docs/preferences.md の「設定値が意図せず失われることが絶対にあってはならない」の設計要件に合わせて、サーバー側の更新条件や compare-and-swap を活用してください。

autoBackupautoSync でプロファイル全体を複数デバイス間で共有できますが、この手順の冒頭だけで非推奨の前提条件や、同期対象・競合時の動作が揃っておりません。指定したいのはプロファイル全体の共有であれば、同一プロファイル共有が非推奨であること、syncBetweenDevices を有効にする項目単位同期とは明確に区別すること、そして autoBackup にプロファイル名が必要なので youNeedToNameYourProfileToEnableAutoBackup もこの手順の前提として記述してください。推奨は項目単位の同期であれば、手順を別プロファイルと syncBetweenDevices の利用に変更してください。

クラウド tombstone の同期を回帰テストで検証してください。

この範囲は有効なレコードと metadata がない旧形式だけを検証しています。clearAccountOverridedeleted: true の tombstone を保存します。より新しい tombstone が、遅延して届いた古い有効レコードで上書きされると、解除したアカウント上書きが別デバイスで復活します。

新しいクラウド tombstone がローカルの有効レコードを無効化するケースと、新しいローカル tombstone をクラウドへ送信するケースを追加してください。
