+# Ollama Translations
+
+Firefox用WebExtension(Manifest V3)。Webページ上で選択した文字列を、ローカルで動作するOllama LLMで翻訳し、選択箇所付近の小型ポップオーバーへストリーミング表示します。
+
+## 特徴
+
+- 文字列選択後、選択範囲付近に翻訳アイコンを表示(押すまでOllamaへは一切通信しません)
+- Ollama REST API(`POST /api/chat`)+ NDJSONストリーミングで逐次表示
+- 会話履歴なしの1-shot翻訳。同時実行は1件で、新規要求時に旧要求を自動Abort
+- Shadow DOMベースのUIでページCSSの影響を受けません
+- 翻訳結果はプレーンテキストとして描画(HTML評価なし)
+- コピー / 再生成 / 閉じる操作に対応
+- 詳細な生成パラメータ設定(temperature / context length / seed / top_k 等)
+
+## セキュリティ方針
+
+- 依存パッケージゼロ(npm / Node.js 不要)。すべてバニラJS
+- Ollama通信はBackgroundのみ。Content Scriptからは直接fetchしません
+- 接続先は `http://localhost:<port>` / `http://127.0.0.1:<port>` のみ許可(validator + client側の二重防御)
+- LLM出力・ページ文字列は `textContent` のみで描画(innerHTML不使用)
+- `eval` / `new Function` / リモートコード不使用
+- 権限は `storage` + localhost系host permissionのみ
+
+詳細は `doc/Security.md` を参照してください。
+
+## ビルド
+
+Node.js不要。PowerShellのみでパッケージ化できます。
+
+```powershell
+# アイコン生成(初回のみ、既に生成済みなら不要)
+pwsh -NoProfile -File tools/make-icons.ps1
+
+# パッケージ (dist/ollama-translations.zip)
+pwsh -NoProfile -File build.ps1
+```
+
+## Firefoxへのロード(一時アドオン)
+
+1. Firefoxで `about:debugging#/runtime/this-firefox` を開く
+2. 「一時的なアドオンを読み込む…」をクリック
+3. 本リポジトリの `manifest.json` を選択
+
+## Ollamaの準備
+
+1. [Ollama](https://ollama.com/) をインストールし、`ollama serve`(またはアプリを起動)で `http://localhost:11434` を立ち上げる
+2. 翻訳用モデルをpullする(例):
+
+```powershell
+ollama pull llama3.2
+```
+
+3. 拡張機能のオプション画面(ツールバーアイコン → 「詳細設定を開く」)でモデルを選択して保存
+
+## テスト
+
+ブラウザで `tests/test.html` を開くと単体・結合テスト(71件)が実行されます。オプション画面下部の「開発者向け: テストを実行」リンクからも開けます。
+
+テストは npm / Node.js を使わず、自作ランナーでブラウザ内実行されます。
+
+## 使用WebExtensions API一覧
+
+| API | 用途 |
+|---|---|
+| `storage.local` | 設定の保存・復元 |
+| `storage.onChanged` | 設定変更通知(Content/Background同期) |
+| `runtime.connect` / `runtime.Port` | 翻訳ストリーミング通信 |
+| `runtime.sendMessage` / `onMessage` | モデル一覧取得(popup/options) |
+| `runtime.openOptionsPage` | オプション画面起動 |
+| `content_scripts`(manifest宣言) | ページへの注入 |
+
+## 要求permissionsと理由
+
+| 権限 | 理由 |
+|---|---|
+| `storage` | 設定の永続化(EN-01/Spec §5) |
+| `http://localhost/*`, `http://127.0.0.1/*` | ローカルOllamaへのfetch。Firefoxはmatch patternでポート番号指定不可(bug 1362809/1468162)のため任意ポート一致とし、実際の接続先はアプリ側validatorでlocalhost/127.0.0.1のみに制限 |
+
+## 既知の制限(初期版)
+
+- iframe内の選択文字列には非対応
+- Firefox内蔵PDF Viewer・Reader View・about:系ページには非対応
+- 翻訳履歴・チャットUIなし
+- Markdown/HTMLリッチレンダリングなし(プレーンテキストのみ)
+- Chrome/Edge非対応(Firefox優先)
+- `tfs_z` / `mirostat*` オプション未対応

+
+## 1. 設計概要
+
+本拡張は、Webページとの接点をContent Scriptに限定し、権限を伴うOllama通信と設定管理をBackgroundへ分離する。
+
+```text
+Web Page
+ │
+ │ selection
+ ▼
+Content Script
+ │ runtime.Port
+ ▼
+Background
+ │ fetch / HTTP
+ ▼
+Ollama
+ │ streaming
+ ▼
+Background
+ │ runtime.Port
+ ▼
+Content Script
+ │
+ ▼
+Shadow DOM Popover
+```
+
+設計原則:
+- ページ由来データは信頼しない。
+- Content Scriptは最小責務とする。
+- Ollama通信はBackgroundのみ(Ollama REST API + Fetch API + NDJSON streaming)。
+- UI文字列はHTMLとして評価しない。
+- 翻訳要求は常に1-shot。
+- 同時翻訳は1件に制限。
+- 設定値はUIだけでなくBackgroundでも検証する。
+- Ollama接続先は初期版ではlocalhost / 127.0.0.1 + 任意ポートのみ許可する。
+
+---
+
+## 2. コンポーネント構成
+
+| コンポーネント | 主責務 |
+|---|---|
+| `content/selection-controller` | Selection検出、Range位置取得 |
+| `content/action-button` | 翻訳アイコン表示/非表示 |
+| `content/translation-popover` | 翻訳結果UI、stream描画、copy/regenerate/close |
+| `content/port-client` | Backgroundとの長期接続 |
+| `background/message-router` | Content Scriptからのrequest受信・validation |
+| `background/translation-session` | requestId、AbortController、active stream管理 |
+| `background/ollama-client` | Ollama REST API呼び出し(fetch + NDJSON streaming) |
+| `background/settings-service` | storage読書き、default、validation |
+| `popup` | 有効/無効、簡易設定、Options起動 |
+| `options` | 全設定UI |
+| `shared/settings-schema` | 設定型、既定値、範囲 |
+| `shared/messages` | runtime message型定義 |
+| `shared/constants` | 最大選択長等 |
+
+---
+
+## 3. 推奨ディレクトリ構成
+
+```text
+/
+├─ manifest.json
+├─ package.json
+├─ src/
+│ ├─ background/
+│ │ ├─ index.js
+│ │ ├─ message-router.js
+│ │ ├─ translation-session.js
+│ │ ├─ ollama-client.js
+│ │ └─ settings-service.js
+│ ├─ content/
+│ │ ├─ index.js
+│ │ ├─ selection-controller.js
+│ │ ├─ action-button.js
+│ │ ├─ translation-popover.js
+│ │ ├─ port-client.js
+│ │ └─ content.css
+│ ├─ popup/
+│ │ ├─ popup.html
+│ │ ├─ popup.js
+│ │ └─ popup.css
+│ ├─ options/
+│ │ ├─ options.html
+│ │ ├─ options.js
+│ │ └─ options.css
+│ └─ shared/
+│ ├─ settings-schema.js
+│ ├─ messages.js
+│ ├─ prompt.js
+│ └─ constants.js
+├─ tests/
+│ ├─ unit/
+│ └─ integration/
+└─ docs/
+ ├─ Specifications.md
+ └─ Design.md
+```
+
+実際のビルド方式に応じて配置は調整してよいが、責務分離は維持する。
+
+---
+
+## 4. Manifest設計
+
+概念例:
+
+```json
+{
+ "manifest_version": 3,
+ "name": "Selected Text Translator",
+ "version": "0.1.0",
+ "permissions": ["storage"],
+ "host_permissions": ["http://localhost/*", "http://127.0.0.1/*"],
+ "background": {
+ "scripts": ["background.js"],
+ "type": "module"
+ },
+ "content_scripts": [
+ {
+ "matches": ["http://*/*", "https://*/*"],
+ "js": ["content.js"],
+ "css": ["content.css"],
+ "run_at": "document_idle"
+ }
+ ],
+ "action": {
+ "default_popup": "popup.html"
+ },
+ "options_ui": {
+ "page": "options.html",
+ "open_in_tab": true
+ }
+}
+```
+
+### 4.1 Manifest実装ルール
+- `background.service_worker` は使用しない。
+- `browser_action` は使用しない。
+- `scripting` 権限は初期版では付与しない。
+- `tabs` 権限は付与しない。
+- localhost以外のhost permissionは初期版では付与しない。
+- Firefoxのmatch patternはポート番号指定に対応していない(Firefox bug 1362809 / 1468162)。`http://localhost/*` および `http://127.0.0.1/*` は任意ポートに一致するため、実際に通信してよい接続先はアプリ側Host validatorで `http://localhost:<port>` / `http://127.0.0.1:<port>` のみに限定する。
+
+---
+
+## 5. Content Script設計
+
+### 5.1 Selection取得
+
+標準DOM APIを使用する。
+
+```js
+const selection = window.getSelection();
+const text = selection?.toString().trim();
+
+if (!text) return;
+
+const range = selection.getRangeAt(0);
+const rect = range.getBoundingClientRect();
+```
+
+### 5.2 検出イベント
+初期実装候補:
+- `selectionchange`: 選択状態更新用
+- `mouseup`: 選択確定後の表示タイミング用
+- `keyup`: Shift + Arrow等のキーボード選択対応用
+
+過剰発火を避けるため、UI更新には軽いdebounceを適用してよい。
+
+### 5.3 Action Button表示条件
+
+```text
+selection exists
+AND trimmed text length > 0
+AND text length <= MAX_SELECTION_LENGTH
+AND extension enabled
+```
+
+### 5.4 位置計算
+- `Range.getBoundingClientRect()` を基本とする。
+- 選択が複数行の場合でも最後/全体矩形を基準に配置する。
+- viewport端ではポップオーバーが画面外へ出ないよう補正する。
+- scroll/resize時は再配置または非表示化する。
+
+---
+
+## 6. UI分離設計
+
+### 6.1 Shadow DOM
+
+ページCSSとの衝突を避けるため、Content Scriptが専用host要素を追加し、その内部にShadow DOMを作る。
+
+```js
+const host = document.createElement('div');
+document.documentElement.append(host);
+const shadow = host.attachShadow({ mode: 'open' });
+```
+
+`open/closed` は実装都合で選択可能だが、セキュリティ境界として依存しない。
+
+### 6.2 DOM挿入ルール
+
+禁止:
+```js
+element.innerHTML = translatedText;
+shadowRoot.innerHTML = translatedText;
+```
+
+許可:
+```js
+element.textContent = translatedText;
+```
+
+静的テンプレートHTMLを自前固定文字列として構築する場合も、外部入力を文字列連結しない。
+
+---
+
+## 7. 翻訳ポップオーバー設計
+
+### 7.1 状態
+
+```text
+HIDDEN
+READY
+LOADING
+STREAMING
+COMPLETED
+ERROR
+```
+
+### 7.2 表示内容
+
+| 要素 | 内容 |
+|---|---|
+| Header | 翻訳結果 |
+| Meta | Model名 / Ollama |
+| Body | streaming翻訳本文 |
+| Copy | 完了/途中結果をclipboardへコピー |
+| Regenerate | 同じ選択文字列で再要求 |
+| Close | ポップオーバー非表示 |
+
+### 7.3 UI挙動
+- Icon押下直後にLOADING表示。
+- 最初のchunk受信後STREAMINGへ遷移。
+- 完了イベントでCOMPLETED。
+- Abortされた旧requestのchunkはrequestId不一致なら無視。
+- Error時は再生成可能な状態に戻す。
+
+---
+
+## 8. Runtime通信設計
+
+Streamingには `browser.runtime.connect()` / `runtime.Port` を使用する。
+
+### 8.1 Port名
+
+```text
+translation-stream
+```
+
+### 8.2 Content → Background message
+
+#### translate
+
+```js
+{
+ type: 'translate',
+ requestId: 'uuid-or-random-id',
+ text: 'selected text'
+}
+```
+
+#### cancel
+
+```js
+{
+ type: 'cancel',
+ requestId: '...'
+}
+```
+
+### 8.3 Background → Content message
+
+#### started
+
+```js
+{
+ type: 'started',
+ requestId: '...',
+ model: '...'
+}
+```
+
+#### chunk
+
+```js
+{
+ type: 'chunk',
+ requestId: '...',
+ text: 'partial translation'
+}
+```
+
+#### completed
+
+```js
+{
+ type: 'completed',
+ requestId: '...'
+}
+```
+
+#### error
+
+```js
+{
+ type: 'error',
+ requestId: '...',
+ code: 'OLLAMA_UNAVAILABLE',
+ message: '...'
+}
+```
+
+### 8.4 Validation
+Backgroundは最低限以下を確認する。
+- `type` が既知値か
+- `requestId` がstringか
+- `text` がstringか
+- text lengthが上限以内か
+- 現在のsender/portがContent Script由来か
+
+---
+
+## 9. TranslationSession設計
+
+Backgroundではactive translationを原則1件だけ保持する。
+
+```js
+class TranslationSession {
+ requestId;
+ abortController;
+ sourceText;
+ startedAt;
+}
+```
+
+新しい翻訳要求:
+
+```text
+translate(request B)
+ ↓
+active request Aあり?
+ ├─ yes → Abort A
+ └─ no
+ ↓
+request Bをactiveに設定
+ ↓
+Ollama streaming開始
+```
+
+### 9.1 古いchunk対策
+受信chunkごとにactive requestIdを確認し、不一致なら破棄する。
+
+---
+
+## 10. OllamaClient設計
+
+### 10.1 API
+
+Ollama REST APIをFetch APIで直接呼び出す。`ollama-js`等のサードパーティSDKは使用しない。
+
+概念例:
+
+```js
+const response = await fetch(`${host}/api/chat`, {
+ method: 'POST',
+ headers: { 'Content-Type': 'application/json' },
+ body: JSON.stringify({
+ model: settings.model,
+ messages: [
+ {
+ role: 'system',
+ content: buildSystemPrompt(settings)
+ },
+ {
+ role: 'user',
+ content: selectedText
+ }
+ ],
+ stream: true,
+ think: settings.thinking, // off時は省略
+ options: buildOptions(settings)
+ }),
+ signal: abortController.signal
+});
+
+// NDJSONストリームをバッファリングしつつ行単位でパースする
+const reader = response.body.getReader();
+const decoder = new TextDecoder();
+let buffer = '';
+for (;;) {
+ const { done, value } = await reader.read();
+ if (done) break;
+ buffer += decoder.decode(value, { stream: true });
+ // bufferを行単位で分割し、完全な行のみJSON.parseする
+ // 末尾の不完全行は次回チャンクに持ち越す
+}
+```
+
+### 10.2 System Prompt構築
+
+```text
+BUILTIN_SYSTEM_PROMPT
+
+[User translation preferences]
+USER_SYSTEM_PROMPT
+```
+
+固定promptは常に先頭に置く。
+
+### 10.3 buildOptions
+未設定値はrequest objectへ含めない。
+
+例:
+
+```js
+{
+ temperature: 0.2,
+ num_ctx: 16384,
+ seed: 42,
+ top_k: 40,
+ top_p: 0.9,
+ min_p: 0.05,
+ typical_p: 1.0,
+ repeat_last_n: 64,
+ repeat_penalty: 1.1,
+ presence_penalty: 0.0,
+ frequency_penalty: 0.0,
+ num_keep: 4,
+ num_predict: -1,
+ stop: ['<END>']
+}
+```
+
+Seed可変時は`seed`をoptionsへ含めない設計を優先する。
+
+---
+
+## 11. 設定スキーマ
+
+推奨形:
+
+```js
+{
+ enabled: true,
+ ollamaHost: 'http://localhost:11434',
+ model: '',
+ targetLanguage: 'ja',
+ thinking: false,
+ temperature: 0.2,
+ contextLength: 16384,
+ seedMode: 'random',
+ seedValue: null,
+ userSystemPrompt: '',
+ advanced: {
+ numKeep: null,
+ numPredict: null,
+ topK: null,
+ topP: null,
+ minP: null,
+ typicalP: null,
+ repeatLastN: null,
+ repeatPenalty: null,
+ presencePenalty: null,
+ frequencyPenalty: null,
+ stop: []
+ }
+}
+```
+
+---
+
+## 12. 設定値validation
+
+### 12.1 Basic
+
+| enabled | boolean |
+| ollamaHost | URL形式。**`http://localhost:<port>` または `http://127.0.0.1:<port>` のみ許可(schemeはhttp固定、外部ホスト・LAN IP・httpsは拒否)。必須制限** |
+| model | non-empty string |
+| targetLanguage | 定義済み値 |
+| thinking | `false/true/low/medium/high` 相当 |
+| temperature | 0.0〜2.0、0.1刻み |
+| contextLength | `4096/8192/16384/32768/131072/262144` のいずれか |
+| seedMode | `random/fixed` |
+| seedValue | fixed時のみinteger |
+| userSystemPrompt | string、最大長を設定 |
+
+### 12.2 Advanced
+
+推奨UI step:
+
+| 項目 | step | validation方針 |
+|---|---:|---|
+| num_keep | 1 | integer |
+| num_predict | 1 | integer、-1許容 |
+| top_k | 1 | integer、0以上 |
+| top_p | 0.05 | float |
+| min_p | 0.01 | float |
+| typical_p | 0.05 | float |
+| repeat_last_n | 1 | integer、-1許容 |
+| repeat_penalty | 0.05 | float |
+| presence_penalty | 0.05 | float |
+| frequency_penalty | 0.05 | float |
+| stop | - | string[] |
+
+Ollamaが明示的な最小/最大値を保証していない項目について、UI側で過度に狭い範囲を独自設定しない。型と明らかな不正値を中心に検証する。
+
+---
+
+## 13. Context Length UI設計
+
+固定プリセット:
+
+```js
+const CONTEXT_PRESETS = [
+ 4096,
+ 8192,
+ 16384,
+ 32768,
+ 131072,
+ 262144
+];
+```
+
+UI表示:
+
+```text
+4k ─ 8k ─ 16k ─ 32k ─ 128k ─ 256k
+```
+
+実装上はrange inputのindex値を使用してよい。
+
+```text
+0 => 4096
+1 => 8192
+2 => 16384
+3 => 32768
+4 => 131072
+5 => 262144
+```
+
+モデル自身が対応する最大contextを超える場合、Ollama側でエラーまたは制約される可能性があるため、そのエラーをUIへ返す。
+
+---
+
+## 14. Temperature UI設計
+
+```text
+min=0.0
+max=2.0
+step=0.1
+```
+
+スライダー値は表示用数値と同期する。
+
+```html
+<input type="range" min="0" max="2" step="0.1">
+```
+
+---
+
+## 15. Seed UI設計
+
+```text
+Seed
+[ 可変 ] [ 固定 ]
+
+固定選択時:
+固定値 (整数) [ 42 ▲▼ ]
+```
+
+- random時: seed optionを送らない。
+- fixed時: `seedValue` を整数として送る。
+- Seed Valueはnumber input + spinnerでよい。
+
+---
+
+## 16. Advanced UI設計
+
+数値項目は`input type="number"`相当のUIとする。
+
+例:
+
+```text
+top_p
+[ 0.90 ][▲]
+ [▼]
+```
+
+HTML native spinnerを使用できる場合は活用し、独自実装を増やさない。
+
+stopは複数行textareaとし、1行1sequenceとして保存する。
+
+---
+
+## 17. SettingsService設計
+
+### 17.1 保存
+
+`browser.storage.local` を使用。
+
+### 17.2 読み込み
+1. default settings生成
+2. storage値取得
+3. merge
+4. validation
+5. 不正値はdefaultへフォールバック
+
+### 17.3 設定変更通知
+設定変更時に `browser.storage.onChanged` を使用し、Content Script / Background双方が必要な設定を更新できるようにする。
+
+---
+
+## 18. Security Design
+
+### 18.1 Trust Boundary
+
+```text
+UNTRUSTED
+Web Page / DOM / Selection
+ │
+ ▼
+Content Script
+ │ structured messages only
+ ▼
+PRIVILEGED
+Background / Ollama access / storage
+```
+
+### 18.2 XSS対策
+- 選択文字列をHTML化しない。
+- LLM出力をHTML化しない。
+- Markdown rendererを初期版では導入しない。
+- DOM挿入は`textContent`中心。
+
+### 18.3 Prompt Injection対策
+翻訳用途ではページ本文を命令ではなくデータとして固定system promptで扱う。
+
+ただしLLMの挙動を完全保証するセキュリティ境界としてPromptのみへ依存しない。
+
+### 18.4 Remote Code禁止
+- CDN script禁止。
+- `eval`禁止。
+- `new Function`禁止。
+- remote import禁止。
+- npm依存はbundleに含める。
+
+### 18.5 Storage
+- `storage.local` は暗号化ストレージではない前提。
+- API key等の秘密情報は初期版では扱わない。
+
+### 18.6 Message Validation
+Content側のデータをBackgroundで再検証する。
+
+### 18.7 Resource Abuse
+- MAX_SELECTION_LENGTHを設ける。
+- active translationは1件。
+- 新規requestで旧request abort。
+- 選択だけではrequestを送らない。

+## 19. Error Code設計
+
+| Code | 意味 |
+|---|---|
+| `INVALID_REQUEST` | message形式不正 |
+| `TEXT_EMPTY` | 空文字 |
+| `TEXT_TOO_LONG` | 選択長超過 |
+| `OLLAMA_UNAVAILABLE` | Ollama接続不可 |

+
+## 20. Copy設計
+
+Clipboard APIのみを使用する。`document.execCommand('copy')` はdeprecatedのため使用しない。
+
+- コピーはポップオーバーのコピーボタンclick(user activation内)で発生するため、`navigator.clipboard.writeText()` をそのハンドラ内で直接呼び出す。
+- 書き込み失敗時は「コピーできませんでした」等の簡潔なメッセージをポップオーバーへ表示するのみとし、deprecated APIへフォールバックしない。
+- Firefox実機でclipboard動作を確認する。
+
+コピー対象は現在表示中の翻訳プレーンテキストのみ。
+
+---
+
+## 21. モデル一覧取得
+
+BackgroundのOllamaClientからモデル一覧取得APIを呼び、Settings UIへ返す。
+
+要件:
+- Ollama未起動時は空一覧 + 接続エラー表示。
+- 取得成功時はselect候補へ反映。
+- 保存済みmodelが一覧にない場合は警告表示。

+# Security.md
+
+## 1. Purpose
+
+This document defines the mandatory security constraints and implementation rules for the Firefox WebExtension project.
+
+The implementation agent MUST treat this file as a normative development policy together with `Specifications.md` and `Design.md`.
+
+When there is a conflict between convenience and this security policy, this policy takes precedence unless the project owner explicitly changes the requirement.
+
+---
+
+## 2. Security Objectives
+
+| ID | Objective |
+|---|---|
+| SEC-001 | Minimize the extension's attack surface. |
+| SEC-002 | Avoid third-party build-time and runtime dependency supply-chain risk. |
+| SEC-003 | Treat all web page content as untrusted input. |
+| SEC-004 | Prevent selected text and LLM output from being evaluated as HTML or JavaScript. |
+| SEC-005 | Restrict privileged WebExtension operations to the minimum required components. |
+| SEC-006 | Restrict network communication to the configured Ollama endpoint. |
+| SEC-007 | Use current Firefox WebExtensions APIs and avoid deprecated or obsolete APIs. |
+| SEC-008 | Keep the implementation auditable without a package manager or generated dependency tree. |
+
+---
+
+## 3. Dependency Policy
+
+### 3.1 Mandatory Rules
+
+The project MUST be developed without Node.js or JavaScript package managers.
+
+The following are prohibited:
+
+- Node.js as a required development or runtime dependency
+- npm
+- yarn
+- pnpm
+- bun package management
+- `node_modules`
+- third-party JavaScript packages
+- third-party CSS frameworks
+- remote JavaScript
+- remote CSS
+- remote fonts
+- CDN-hosted runtime resources
+
+The project SHOULD NOT contain `package.json`.
+
+All resources required at runtime MUST be included directly in the extension package or supplied by Firefox/Web Platform standard APIs.
+
+### 3.2 Allowed Technologies
+
+The implementation MAY use:
+
+- HTML
+- locally stored CSS
+- vanilla JavaScript
+- Firefox WebExtensions APIs
+- standard DOM APIs
+- Fetch API
+- Streams API
+- `TextDecoder` / `TextDecoderStream`
+- standard `JSON` APIs
+- locally bundled PNG/SVG assets
+- inline SVG created by the project
+- operating-system fonts through CSS generic/system font families
+
+### 3.3 CSS and Asset Policy
+
+All application CSS MUST be owned by this project and stored locally in the repository.
+
+Do not download and vendor a CSS framework unless explicitly approved.
+
+Preferred approach:
+
+```text
+content.css
+popup.css
+options.css
+```
+
+External resources such as the following MUST NOT be used:
+
+```text
+Google Fonts
+Font Awesome CDN
+Material Icons CDN
+Bootstrap CDN
+Tailwind CDN
+jsDelivr
+unpkg
+cdnjs
+```
+
+Icons SHOULD be:
+
+1. project-owned local SVG/PNG files, or
+2. inline SVG defined directly by the application.
+
+System fonts SHOULD be used, for example:
+
+```css
+font-family: system-ui, sans-serif;
+```
+
+---
+
+## 4. Ollama Integration Policy
+
+### 4.1 No Ollama JavaScript SDK Dependency
+
+The project MUST NOT require `ollama-js`.
+
+The extension MUST communicate with Ollama directly using the official Ollama HTTP API and the browser Fetch API.
+
+The intent is to eliminate npm/package-manager supply-chain dependencies.
+
+### 4.2 Required API Scope
+
+The initial implementation SHOULD require only the minimum Ollama endpoints needed by the specification.
+
+Expected endpoints:
+
+| Endpoint | Purpose |
+|---|---|
+| `GET /api/tags` | Retrieve installed models. |
+| `POST /api/chat` | Perform translation generation using streaming. |
+
+Do not add Ollama API endpoints unless required by a defined feature.
+
+### 4.3 Streaming
+
+Translation MUST use streaming responses.
+
+The Ollama client module MUST:
+
+- parse streamed response data safely;
+- tolerate chunk boundaries that do not align with JSON object boundaries;
+- cancel the current request when a newer translation request supersedes it;
+- use `AbortController` or equivalent standard browser functionality;
+- propagate only validated translation text to the content script.
+
+### 4.4 Ollama Endpoint
+
+Default endpoint:
+
+```text
+http://localhost:11434
+```
+
+The endpoint MAY be configurable according to the product specification. In the initial version, the configured endpoint MUST be limited to `http://localhost:<port>` or `http://127.0.0.1:<port>`. External hosts, LAN IPs, and HTTPS endpoints MUST be rejected by validation.
+
+The implementation MUST validate the configured value before use, and the Ollama client MUST re-verify the target host immediately before each request (defense in depth).
+
+The background component MUST be the only component that communicates directly with Ollama.
+
+Content scripts MUST NOT directly call Ollama.
+
+---
+
+## 5. Firefox WebExtensions Policy
+
+### 5.1 Manifest
+
+The extension MUST use Manifest V3.
+
+Firefox-specific behavior MUST be verified against current MDN documentation before implementation.
+
+Do not blindly copy Chromium-specific Manifest V3 examples.
+
+### 5.2 Background Implementation
+
+For Firefox, use the supported background mechanism documented for Firefox.
+
+Do NOT assume Chromium's:
+
+```json
+"background": {
+ "service_worker": "background.js"
+}
+```
+
+is supported by Firefox.
+
+The implementation agent MUST verify the current Firefox support status before changing the background model.
+
+### 5.3 APIs to Prefer
+
+Use modern APIs where required:
+
+| Purpose | Preferred API |
+|---|---|
+| Toolbar action | `action` |
+| Extension storage | `storage.local` |
+| Long-lived extension communication | `runtime.connect()` / `runtime.Port` |
+| One-shot extension messages | `runtime.sendMessage()` |
+| Dynamic script injection, only if needed | `scripting.executeScript()` |
+
+### 5.4 APIs / Patterns to Avoid
+
+Do not introduce the following unless explicit project requirements justify them:
+
+- Manifest V2
+- `browser_action`
+- `browserAction.*`
+- `tabs.executeScript()`
+- `tabs.insertCSS()`
+- `runtime.getBackgroundPage()`
+- `extension.getBackgroundPage()`
+- `window.localStorage` for extension settings
+- `externally_connectable`
+- `runtime.onMessageExternal`
+- `runtime.onConnectExternal`
+- `nativeMessaging`
+- `webRequest`
+- `cookies`
+- `history`
+- `bookmarks`
+- `downloads`
+- unnecessary `tabs` permission
+- unnecessary `scripting` permission
+
+The implementation MUST verify whether any WebExtensions API it intends to add is deprecated, obsolete, Firefox-incompatible, or unnecessarily privileged.
+
+---
+
+## 6. Permission Minimization
+
+The extension MUST request only permissions required by implemented features.
+
+Expected initial permission set:
+
+```text
+storage
+```
+
+Expected host permission:
+
+```text
+http://localhost/*
+http://127.0.0.1/*
+```
+
+Firefox match patterns do not support port numbers (Firefox bug 1362809 / 1468162). Therefore the patterns above match any port on localhost. The application MUST restrict the actual connection target to `http://localhost:<port>` or `http://127.0.0.1:<port>` via its own host validation before any Ollama request.
+
+or the minimum equivalent required by the final Ollama-host design.
+
+Page access MAY require content-script match patterns for HTTP/HTTPS pages because translation is initiated by selecting page text.
+
+Do not add broad privileged permissions for convenience.
+
+Every newly introduced permission MUST be justified in code review.
+
+---
+
+## 7. Trust Boundaries
+
+The system has three primary trust zones.
+
+```text
+Untrusted Web Page
+ |
+ | selected text
+ v
+Content Script
+ |
+ | validated extension messages
+ v
+Background
+ |
+ | HTTP
+ v
+Ollama
+```
+
+### 7.1 Web Page
+
+All page content MUST be considered untrusted.
+
+This includes:
+
+- text selected by the user;
+- DOM content;
+- attributes;
+- page-generated text;
+- scripts;
+- event data;
+- iframe content;
+- strings that resemble prompts or instructions.
+
+The presence of text such as:
+
+```text
+Ignore previous instructions...
+```
+
+MUST NOT cause that text to be treated as an application instruction.
+
+Selected web content is translation data, not trusted control input.
+
+### 7.2 Content Script
+
+The content script is responsible only for tasks that require page access, including:
+
+- obtaining the user's current text selection;
+- positioning the translation action icon;
+- rendering the translation popover;
+- forwarding translation requests;
+- receiving streamed translation text;
+- handling local UI interaction.
+
+It MUST NOT be responsible for privileged network communication with Ollama.
+
+### 7.3 Background
+
+The background component owns privileged application operations:
+
+- Ollama HTTP communication;
+- request lifecycle management;
+- configuration access where appropriate;
+- message validation;
+- request cancellation;
+- Ollama response parsing.
+
+---
+
+## 8. DOM and XSS Rules
+
+### 8.1 Plain-Text Rendering
+
+Page-derived text and LLM-generated text MUST be rendered as plain text.
+
+Use safe DOM APIs such as:
+
+```js
+element.textContent = value;
+```
+
+Do NOT use untrusted content with:
+
+```js
+element.innerHTML = value;
+element.outerHTML = value;
+shadowRoot.innerHTML = value;
+document.write(value);
+```
+
+### 8.2 No HTML Interpretation
+
+The translation result is plain text.
+
+Do not implement Markdown rendering, HTML rendering, or rich-text parsing unless explicitly added as a later requirement and separately security-reviewed.
+
+### 8.3 No Dynamic Code Execution
+
+The following are prohibited:
+
+```text
+eval()
+new Function()
+setTimeout(string)
+setInterval(string)
+```
+
+No selected page content, setting, LLM response, or remote response may be executed as JavaScript.
+
+---
+
+## 9. Shadow DOM Policy
+
+The translation UI SHOULD use Shadow DOM where practical to isolate extension UI styling from page CSS.
+
+Primary reasons:
+
+- reduce CSS collisions;
+- reduce page-style interference;
+- contain translation UI styles;
+- improve predictable layout.
+
+Shadow DOM MUST NOT be treated as an XSS security boundary.
+
+LLM responses and page text inside a shadow root MUST still use plain-text rendering.
+
+---
+
+## 10. Page Script Isolation
+
+The extension SHOULD rely on the normal WebExtensions content-script isolation boundary.
+
+Do not bridge page scripts and extension scripts unless a future requirement makes this unavoidable.
+
+The following SHOULD NOT be used:
+
+- `wrappedJSObject`
+- `exportFunction`
+- `cloneInto`
+- custom page-script injection
+- page-controlled `window.postMessage` communication
+
+If page-script communication becomes necessary later, it requires an explicit security design update.
+
+---
+
+## 11. Message Validation
+
+All messages received by privileged extension components MUST be validated.
+
+Example translation request shape:
+
+```js
+{
+ type: "translate",
+ requestId: "...",
+ text: "..."
+}
+```
+
+The receiver MUST validate at least:
+
+- message is an object;
+- known `type`;
+- expected fields are present;
+- `text` is a string;
+- `requestId` is a string;
+- text length is within defined limits;
+- unsupported fields do not alter privileged behavior.
+
+Do not dispatch privileged behavior using arbitrary method names supplied by messages.
+
+Avoid patterns such as:
+
+```js
+handlers[message.method](message);
+```
+
+unless `message.method` is strictly allow-listed.
+
+---
+
+## 12. Input Limits and Resource Abuse
+
+Selected text MUST have a maximum allowed size.
+
+The exact product limit MAY be defined in `Specifications.md`, but an implementation limit MUST exist.
+
+The purpose is to reduce:
+
+- accidental huge requests;
+- malicious resource consumption;
+- unnecessarily long model generation;
+- UI hangs;
+- memory pressure.
+
+If input exceeds the allowed limit, the extension MUST fail safely and provide a user-visible error.
+
+Repeated translation requests MUST cancel obsolete in-flight requests.
+
+---
+
+## 13. LLM Prompt Boundary
+
+The application MUST maintain a separation between:
+
+1. application-controlled system instructions;
+2. user-configurable system instructions;
+3. selected page text.
+
+The application-controlled prompt MUST state that selected page content is translation material and must not be interpreted as instructions.
+
+Selected text MUST NOT be concatenated into trusted system instructions.
+
+Preferred conceptual request structure:
+
+```text
+system:
+ application-controlled translation rules
+ + validated user translation preferences
+
+user:
+ selected page text
+```
+
+---
+
+## 14. Settings Validation
+
+Every configurable Ollama generation value MUST be validated before being sent to Ollama.
+
+Validation MUST include:
+
+- expected type;
+- finite numeric value where applicable;
+- supported range;
+- integer-only constraints where applicable;
+- allowed enum values;
+- context-length preset membership;
+- string length limits.
+
+Invalid stored values MUST NOT be passed directly to Ollama.
+
+The implementation SHOULD fall back to safe defaults or request correction from the user.
+
+---
+
+## 15. Seed Security / Correctness Rule
+
+Seed configuration MUST distinguish between:
+
+- variable/random behavior;
+- fixed deterministic integer seed.
+
+When fixed seed mode is enabled, the value MUST be validated as an integer.
+
+When variable mode is enabled, the implementation MUST use the Ollama/API-supported behavior defined in the specification and MUST NOT generate executable or unsafe random data.
+
+---
+
+## 16. Storage Rules
+
+Use:
+
+```text
+browser.storage.local
+```
+
+for extension configuration.
+
+Do not use page `localStorage` for extension settings.
+
+The implementation MUST assume `storage.local` is not encrypted.
+
+Do not store:
+
+- passwords;
+- arbitrary secrets;
+- private authentication tokens;
+
+unless a later requirement explicitly adds such functionality and the security model is revised.
+
+The initial local-Ollama design SHOULD require no secret credentials.
+
+---
+
+## 17. Content Security Policy
+
+Keep Firefox's extension CSP as restrictive as practical.
+
+Do not weaken CSP merely to make a library or framework work.
+
+Do not enable:
+
+- remote script execution;
+- `unsafe-eval`;
+- arbitrary inline executable JavaScript.
+
+JavaScript SHOULD be stored in local `.js` files where applicable.
+
+HTML event attributes such as the following SHOULD NOT be used:
+
+```html
+<button onclick="...">
+```
+
+Prefer JavaScript event listeners:
+
+```js
+button.addEventListener("click", handler);
+```
+
+---
+
+## 18. Remote Resource Ban
+
+At runtime, the extension MUST NOT load executable or styling resources from the Internet.
+
+Prohibited runtime resources include:
+
+- JavaScript;
+- CSS;
+- web fonts;
+- icon libraries;
+- UI frameworks;
+- remotely hosted HTML fragments.
+
+The only intended network communication is application data communication with the configured Ollama service.
+
+A future feature that adds any other remote service requires explicit review and an update to this file.
+
+---
+
+## 19. Build and Packaging
+
+The project SHOULD be directly loadable as a Firefox temporary extension without a build step.
+
+Expected development workflow:
+
+```text
+edit source files
+ ->
+about:debugging
+ ->
+This Firefox
+ ->
+Load Temporary Add-on
+ ->
+select manifest.json
+```
+
+A build system MUST NOT be introduced unless an explicit requirement justifies it.
+
+Packaging SHOULD consist of the project files required by the WebExtension package, excluding tests and development-only files where appropriate.
+
+---
+
+## 20. Testing Security Requirements
+
+Security-sensitive behavior MUST be tested.
+
+Minimum cases:
+
+| Test | Expected Result |
+|---|---|
+| Selected text contains `<script>` | Displayed as text, never executed. |
+| LLM returns HTML tags | Displayed as text. |
+| LLM returns `<img onerror=...>` | Displayed as text. |
+| Selected text contains prompt-injection language | Treated only as translation input. |
+| Oversized selected text | Rejected safely. |
+| Invalid numeric option | Rejected or replaced with safe default. |
+| Invalid context preset | Rejected. |
+| Unknown message type | Ignored/rejected. |
+| Rapid repeated translation requests | Previous request is cancelled. |
+| Ollama unavailable | Safe error UI, no exception leak to page. |
+| Malformed Ollama stream chunk | Parser fails safely without executing content. |
+| Page has hostile CSS | Translation UI remains usable where practical. |
+| Page script inspects DOM | No privileged extension object is exposed. |
+
+---
+
+## 21. Logging
+
+Do not log full selected text or full translation results by default.
+
+Development logging SHOULD avoid unnecessary disclosure of page content.
+
+Do not log secrets if credential support is ever added.
+
+Error logs SHOULD contain technical diagnostics without unnecessarily reproducing user-selected text.
+
+---
+
+## 22. Error Handling
+
+Errors MUST fail closed rather than enabling broader privileges or unsafe fallback behavior.
+
+Examples:
+
+- If Ollama host validation fails, do not attempt arbitrary network access.
+- If JSON streaming parsing fails, stop or recover safely.
+- If a setting cannot be validated, use a documented safe default or reject the operation.
+- If content-script messaging fails, do not fall back to page-script execution.
+
+---
+
+## 23. Source Review Policy
+
+Before adding any new external code, dependency, browser API, or permission, the implementation agent MUST answer:
+
+1. Is this required by `Specifications.md`?
+2. Can the same requirement be implemented with a browser/WebExtensions standard API?
+3. Does this introduce a package-manager dependency?
+4. Does this introduce a runtime network dependency?
+5. Does this require a new Firefox permission?
+6. Is the API current and supported by Firefox?
+7. Does it expand the trust boundary?
+8. Can the implementation remain simpler without it?
+
+If the feature can reasonably be implemented without the new dependency or privilege, prefer the dependency-free / lower-privilege implementation.
+
+---
+
+## 24. Explicitly Prohibited Design Changes
+
+Without project-owner approval, the implementation agent MUST NOT:
+
+- add npm dependencies;
+- introduce Node.js tooling;
+- add a JavaScript framework;
+- add a CSS framework;
+- load assets from a CDN;
+- load Google Fonts or other remote fonts;
+- add `ollama-js`;
+- replace direct Ollama REST calls with a third-party client;
+- request unrelated Firefox permissions;
+- introduce Manifest V2 compatibility code;
+- introduce Chromium-only service-worker assumptions into Firefox code;
+- render LLM output using HTML;
+- execute page or LLM content;
+- expose privileged extension functions to page JavaScript;
+- silently add telemetry or analytics;
+- send selected text anywhere other than the explicitly configured Ollama endpoint.
+
+---
+
+## 25. Privacy Requirements
+
+Selected text can contain private or sensitive page content.
+
+Therefore:
+
+- selected text MUST only be sent to the configured Ollama endpoint;
+- the extension MUST NOT send telemetry;
+- the extension MUST NOT send analytics;
+- the extension MUST NOT contact external logging services;
+- the extension MUST NOT automatically fall back to a cloud LLM;
+- connection failures MUST NOT cause data to be sent to another provider;
+- the UI SHOULD make the configured Ollama host visible to the user.
+
+If cloud Ollama support is added later, it must be an explicit user configuration and requires a privacy/security design update.
+
+---

+
+## 1. 概要
+
+### 1.1 目的
+Firefox上でユーザーがWebページ内の文字列を選択した際、選択範囲付近に小さな翻訳アイコンを表示し、ユーザーがそのアイコンを押すとOllama経由のLLMで翻訳を実行し、ページ上の小型ポップオーバーにストリーミング表示するFirefox WebExtensionを実装する。
+
+### 1.2 基本方針
+- Firefox WebExtensions APIを使用する。
+- Manifest V3を採用する。
+- Firefox向け実装を優先し、Chromium互換性は必須要件としない。
+- Ollamaとの通信は公式Ollama REST APIをFetch APIで直接呼び出すことにより行う(`ollama-js`等のサードパーティライブラリは使用しない)。
+- Ollama呼び出しは `POST /api/chat` + `stream: true`(NDJSON streaming)のみを使用する。
+- 会話履歴は保持せず、翻訳要求ごとに独立した1-shotリクエストとする。
+- Webページ上の翻訳UIはチャットUIではなく、選択箇所付近の軽量なポップオーバーとする。
+- ページ本文およびLLM出力は常にプレーンテキストとして扱い、HTMLとして評価しない。
