 All notable changes to Reasonix. The format follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/);
 this project uses [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

+## [0.53.1] — 2026-05-27
+
+**Install fix — `npx reasonix` no longer crashes on `EUNSUPPORTEDPROTOCOL`.**
+The 0.52.0 refactor that inlined Ink as a workspace package (#1947)
+left `"ink": "workspace:*"` in runtime `dependencies`. tsup already
+bundles ink into `dist/`, so the runtime never resolves it — but npm
+on consumer machines parses the declaration and rejects the
+unresolvable `workspace:` protocol. Removed from runtime deps; the
+bundled ink in `dist/` is the implementation. 0.53.0 is deprecated
+on npm.
+
+## [0.53.0] — 2026-05-27
+
+**Force-summary respects the active model.** Context-guard and stuck-state
+recovery were calling `client.chat({ model: "deepseek-v4-flash" })`
+regardless of the user's configured model (#1979). Third-party
+DeepSeek-compatible endpoints (mimo, self-hosted, Azure forks) that
+don't expose flash returned 400 on every recovery — the session looked
+like it lost context (the messages were still there) and the user had
+no way back without `/clear`. Force-summary now uses `this.model` with
+`thinking: "disabled"` to keep reasoning tokens off the bill even when
+the active model is pro.
+
+**Web search — Brave backend.** `web_search` now supports the Brave
+Search API as an alternative backend (#1916), alongside the existing
+Bing / Tavily / Ollama-cloud paths. Configurable per-instance.
+
+**Desktop — workspace switcher.** Sidebar exposes a workspace
+switcher (#1908) so multiple project roots can be juggled without
+restarting the app. Bundled-app version surfacing for desktop is
+unified through the same sync pipeline as the CLI.
+
+**Desktop — fixes.**
+- Per-tab hook firing for Pre/PostToolUse, UserPromptSubmit, Stop
+  (#1984) — hooks were leaking across tabs in multi-session windows
+- Clear the pending assistant on error so the spinner stops (#1985,
+  fixes #1660)
+- `/skill` and `/skills` slash commands wired through (#1978, fixes
+  #1969)
+- Context token meter refreshes after each turn (#1964)
+- Preserve session context across abort (#1938)
+- `\[ \]` and `\( \)` math delimiters now render in markdown (#1923)
+- Windows file opening normalizes path separators (#1914)
+- Settings allow clearing base URL and editor fields (#1905)
+
+**Dashboard / web.**
+- Dashboard session refresh no longer skips updates (#1917)
+- "New Chat" label stays on one line (#1924)
+- Server-snapshot helpers fully typed (#1961)
+
+**Config / auth.** `saveApiKey` now overrides a stale `DEEPSEEK_API_KEY`
+env var so the UI save takes effect immediately (#1982) — previously
+the env shadow won and the user had to relaunch.
+
+**QQ adapter.** `/qq` defaults to markdown replies (#1941); the
+previous plain-text default lost code blocks and lists.
+
+**Networking / fetch.** `web_fetch` falls back to DNS-over-HTTPS when
+the system resolver returns RFC1918 / link-local addresses (#1944) —
+some captive portals and split-horizon DNS configs hand back fake
+internal IPs and the fetch then connects to the wrong host. CLI
+`doctor` accepts a custom `/models` endpoint instead of hard-coding
+DeepSeek's (#1972).
+
+**Truncation / encoding.**
+- Slice boundaries align to UTF-16 codepoints so multi-code-unit
+  characters can't be split mid-surrogate (#1976, includes #1970)
+- Truncated-result-saver falls back to `~/.reasonix` when `rootDir`
+  resolves to the filesystem root (#1974)
+- Lone surrogates are sanitized in chat payloads before serialization
+  (#1939)
+
+**TUI — CardStream measure loop.** Break the
+measure→render→measure feedback loop that could pin CPU on resize
+(#1958).
+
+**Errors / ACP.** Structured `errorDetail` propagates through loop,
+transcript, and ACP wire format (#1965 + follow-up) so external
+clients see the same fault classification the CLI does.
+
+**Internals.** Inline the ink runtime as a workspace package (#1947) —
+last step of the `@esengine/ink` in-tree work started in 0.52.0.
+
+**Misc.**
+- Generated-script shell `cwd` guidance fixed (#1937)
+- AtomGit star badge in README (#1954)
+

-> [!TIP]
-> **キャッシュの安定性はオンにする「機能」ではなく、ループそのものが前提として設計された不変条件です。** これこそが Reasonix が DeepSeek 専用である理由であり、すべてのレイヤーがバイト単位で安定したプレフィックスキャッシュの仕組みに合わせて調整されています。
-
-> [!NOTE]
-> **実ユーザーの1日（2026-05-01）:** 入力トークン 4億3,500万、**キャッシュヒット率 99.82%**、同じワークロードを `v4-flash` でキャッシュなしに実行した場合の約 \$61 に対して、わずか約 \$12 で済んでいます — 詳しくは[ケーススタディ](./benchmarks/real-world-cache/README.md)を参照。キャッシュ可能なバイト列を提供するのは DeepSeek ですが、それを長時間のセッションにわたってキャッシュ可能に保つのが [Pillar 1](./docs/ARCHITECTURE.md#pillar-1--cache-first-loop) の4つの仕組みです。

-## インストール
-
-Node ≥ 22 が必要です。macOS · Linux · Windows（PowerShell · Git Bash · Windows Terminal）で動作します。
-
-`reasonix` コマンドを `PATH` 上で使えるようにしたい場合は、Reasonix をグローバルにインストールします:
-
-~~~bash
-npm install -g reasonix
-reasonix code my-project   # 初回実行時に DeepSeek API キーを貼り付け。以降は保存される
-~~~
-
-または、グローバルインストールせずに一度だけ実行することもできます:
-
-~~~bash
-cd my-project
-npx reasonix code          # デフォルトでは常に最新のパッケージを使用
-~~~
-
-[DeepSeek API キーを取得 →](https://platform.deepseek.com/api_keys) · フラグは `reasonix code --help` を参照。
-
-Reasonix を毎日使うなら、グローバルインストールが最もシンプルな方法です。とりあえず試してみたいだけなら `npx` を使ってください。
-
-**キー入力を減らしたい？** より短い `dsnix` エイリアスが同じ CLI を指します:
-
-~~~bash
-npm install -g dsnix       # PATH 上に `dsnix` を公開。reasonix に依存
-npx dsnix@latest code      # より短いコマンドで一度だけ実行
-~~~
-
-`npm install -g reasonix` でグローバルインストールすると `dsnix` のシムも PATH 上に配置されるため、2つは相互に置き換え可能です。
-
-サブコマンドなしの `reasonix`（裸の `reasonix`）はカレントディレクトリで `code` を起動します — `reasonix` と入力するのは `reasonix code` と等価です。
-
-| コマンド | 用途 |
-|---|---|
-| `reasonix` / `reasonix code [dir]` | コーディングエージェント。**ここから始めてください。** |
-| `reasonix chat` | プレーンなチャット — ファイルシステムやシェルのツールなし。 |
-| `reasonix run "task"` | 一度だけ実行し、stdout にストリーミング。パイプ向き。 |
-| `reasonix doctor` | ヘルスチェック: Node、API キー、MCP の配線。 |
-| `reasonix update` | Reasonix 自体をアップグレード。 |
-
-その他のサブコマンド（`replay` · `diff` · `events` · `stats` · `index` · `mcp` · `prune-sessions`）は `reasonix --help` と [CLI リファレンス](https://esengine.github.io/DeepSeek-Reasonix/#cli)にあります。
-
-### QQ チャンネル
-
-QQ は既存の `chat`、`code`、またはデスクトップのセッションをリモートチャンネルとして拡張できます。これは独立したランタイムモードではなく、現在のセッションフローの一部です。
-
- CLI: セッションを開始し、`/qq connect` を実行
- デスクトップ: `Settings -> General -> QQ Channel` を開く
-
-接続すると、QQ のメッセージを現在のセッションに取り込み、アシスタントの返信を QQ に転送し、その後のやり取りをリモートで継続できます。
-
-詳しいセットアップ、デスクトップのクイックスタート、トラブルシューティングは [QQ チャンネルのセットアップ](./docs/qq-connect.md)を参照してください。
-
-### デスクトップクライアント（プレリリース）
-
-同じループの GUI が欲しいユーザー向けのネイティブ Tauri クライアント。マルチタブ対応で、右パネルにはこのセッションでエージェントが読み取り・編集したファイルが表示され、下部には同じコスト / キャッシュ / トークンのメーターがリアルタイムで表示されます。同じ DeepSeek API キー、同じ `~/.reasonix` 設定を使い、デスクトップ版は独自の Node ランタイムを同梱するため、別途 `npm install` する必要はありません。
-
-各プラットフォームのインストーラーは [GitHub Releases](https://github.com/esengine/DeepSeek-Reasonix/releases) からダウンロードできます。デスクトップ版は **プレリリース** として提供されます: ループとプロトコルは CLI と同じですが、UI はまだ磨き込み中で、インストーラーはまだコード署名されていません。
-
- **macOS** — 初回起動時に Gatekeeper に引っかかります。一度きりの対処: `xattr -dr com.apple.quarantine /Applications/Reasonix.app`（または右クリック → 開く → 確認）。
- **Windows** — SmartScreen が「不明な発行元」と警告します。**詳細情報 → 実行** をクリックしてください。
- **Linux** — `.deb` と `.AppImage` はそのまま起動でき、追加の手順は不要です。
-
-CLI が引き続き正規のインターフェースです。CLI に入った機能はすべてデスクトップのコンポーザーからも利用できます。
-
-<details>
-<summary><strong>別のフォルダで作業する · chat と code の違い · スキルを書く</strong></summary>
-
-**別のフォルダで作業する。** Reasonix はファイルシステムツールを起動ディレクトリにスコープします。対象を変えるには `--dir` を渡してください。セッション途中での切り替えは設計上サポートされていません（メモリのパスが古いルートと絡まってしまうため）— 一度終了して再起動してください。
-
-~~~bash
-npx reasonix code --dir /path/to/project
-~~~
-
-**`chat` と `code` の選び方。** `code` がデフォルトであり、ファイルシステム / シェルツールと SEARCH/REPLACE レビューを備えた唯一のモードです。`chat` はより軽量でツールをオフにしたシェルです — MCP は接続しつつディスクアクセスのない思考のパートナーが欲しいときに使ってください。
-
-| 得られるもの | `code` | `chat` |
-|---|---|---|
-| ファイルシステムツール + `edit_file` | ✓ | — |
-| SEARCH/REPLACE → `/apply` レビュー | ✓ | — |
-| シェルツール（ゲート付き） | ✓ | — |
-| プランモード · `/todo` · `/skill new` · `/mcp add` | ✓ | — |
-| メモリ（`remember` / `recall_memory`） | プロジェクト + グローバル | グローバルのみ |
-| 設定からの MCP サーバー · ウェブ検索 · `ask_choice` | ✓ | ✓ |
-| コーディング用システムプロンプト | ✓ | 汎用 |
-| セッションのスコープ | ディレクトリごと | 共有デフォルト |
-
-**最初のスキルを書く。** リモートレジストリはありません — 直接書きます。ファイル（`description:` フロントマター + 本文）を編集し、`/skill list` を実行します。本文をインライン展開する代わりに分離したサブエージェントループを生成するには `runAs: subagent` を追加します。
-
-~~~bash
-/skill new my-skill              # <project>/.reasonix/skills/my-skill.md
-/skill new my-skill --global     # プロジェクト横断で使うなら ~/.reasonix/skills
-~~~
-
-**Claude 形式のスキルも読み込まれます。** `<project>/.claude/skills/<name>/SKILL.md` と `~/.claude/skills/` が Reasonix のネイティブパスと並んで読み込まれるため、Claude 形式のスキルを出力するツールはそのまま動きます。例 — 上流アダプターなしで OpenSpec ワークフローを投入する:
-
-~~~bash
-npx openspec init --tools claude    # .claude/skills/openspec-*/SKILL.md を書き出す
-/skill openspec-propose <task>      # その後 Reasonix から呼び出す
-~~~
-

-| [フック](https://esengine.github.io/DeepSeek-Reasonix/configuration.html#hooks) | ライフサイクルイベント時のシェルコマンド。`PreToolUse`（ゲート） · `PostToolUse` · `UserPromptSubmit` · `Stop`。 |
-| [権限](https://esengine.github.io/DeepSeek-Reasonix/configuration.html#permissions) | ワークスペースごとのシェル許可リスト。完全な前方一致。 |
-| [ウェブ検索](https://esengine.github.io/DeepSeek-Reasonix/configuration.html#search) | デフォルトは Mojeek。`/search-engine` でセルフホストの SearXNG や Metaso に切り替え可能。 |
-| [セマンティックインデックス](https://esengine.github.io/DeepSeek-Reasonix/configuration.html#index) | `reasonix index` — ローカルの Ollama または任意の OpenAI 互換の埋め込みエンドポイント。 |

-## Reasonix の何が違うのか
-
-ループは3つの柱を中心に構成されています。それぞれが、汎用的なエージェントフレームワークには見えてすらいない問題を解決します — それらは別のキャッシュの仕組み向けに設計されているからです。

-## 非目標
-
-> [!IMPORTANT]
-> Reasonix には明確な方針があります。あえて *やらない* ことがいくつかあります — あなたの作業に合ったツールを選べるよう、ここに挙げておきます。
-
- **マルチプロバイダーの柔軟性。** あえて DeepSeek 専用にしています。1つのバックエンドに密結合していることは制限ではなく機能です。
- **IDE 統合。** ターミナルファースト。差分は `git diff` に、ファイルツリーは `ls` にあります。ダッシュボードはあくまで補助であり、Cursor の代替ではありません。
- **最難関リーダーボードの推論。** Claude Opus はいまだに一部のベンチマークで勝っています。DeepSeek はコーディングで競争力がありますが、もしあなたの作業が「この認証バグを直す」ではなく「この博士課程レベルの証明を解く」ものなら、Claude から始めてください。
- **エアギャップ / 完全無料。** Reasonix には有料の DeepSeek API キーが必要です。エアギャップ環境やゼロコストでの実行には Aider + Ollama または [Continue](https://continue.dev) を参照してください。

-# Telegram channel setup
-
-Reasonix can attach Telegram to an existing `chat` or `code` session as a remote channel. Telegram is not a third runtime mode.
-
-Once connected, Telegram can:
-
- send normal user messages into the active session
- receive follow-up assistant replies with Telegram Markdown rendering
- continue confirmation, choice, checkpoint, and plan-style follow-up interactions with inline buttons
- expose Reasonix slash commands through the Telegram bot command menu
-
-## Before you start
-
-Prepare these first:
-
- a recent Reasonix release that already includes Telegram support
- a Telegram account
- a Telegram bot token from BotFather
- the numeric Telegram user id that should be allowed to drive Reasonix
-
-Important:
-
- Telegram is fail-closed: the channel refuses to start until `telegram.ownerUserId` or `telegram.allowlist` is configured
- keep the bot token private
- only allow Telegram users you trust to run a code-driving bot
-
-## Get your Telegram bot token
-
-The BotFather UI may change, but the flow is usually:
-
-1. Open Telegram and start a chat with `@BotFather`.
-2. Send `/newbot`.
-3. Follow the prompts for bot name and username.
-4. Copy the bot token BotFather returns.
-
-## Get your Telegram user id
-
-Reasonix access control uses Telegram's numeric user id, not the `@username`.
-
-Common ways to get it:
-
- send a message to a helper bot such as `@userinfobot`
- use Telegram's `getUpdates` API after messaging your bot once
- read it from your own trusted bot tooling
-
-Save this value as `telegram.ownerUserId` or include it in `telegram.allowlist`.
-
-## Connect from the CLI
-
-Start a session first:
-
-~~~bash
-reasonix code
-# or
-reasonix chat
-~~~
-
-Configure access control before connecting. For example, edit `~/.reasonix/config.json`:
-
-~~~json
-{
-  "telegram": {
-    "ownerUserId": "123456789"
-  }
-}
-~~~
-
-Then run:
-
-~~~text
-/telegram connect
-~~~
-
-First-time behavior:
-
-1. Reasonix asks for the Telegram bot token in the current TUI.
-2. Enter `/cancel` to abort.
-3. Reasonix saves the token and enables Telegram auto-start after a successful connection.
-
-If a token is already saved, `/telegram connect` reuses it directly.
-
-You can also pass the token inline:
-
-~~~text
-/telegram connect <botToken>
-~~~
-
-Other Telegram commands:
-
- `/telegram status`
- `/telegram disconnect`
-
-After the first successful connection, later `chat` and `code` sessions auto-start the Telegram channel while it stays enabled.
-
-## Environment variables
-
-You can also configure Telegram through environment variables:
-
-~~~bash
-TELEGRAM_BOT_TOKEN=123456:botfather-token
-TELEGRAM_OWNER_USER_ID=123456789
-TELEGRAM_ALLOWLIST=123456789,987654321
-~~~
-
-Environment values override the saved config for token and access checks. `TELEGRAM_ALLOWLIST` accepts comma- or whitespace-separated ids.
-
-## Typical usage
-
-1. Start `reasonix code` or `reasonix chat`.
-2. Configure `telegram.ownerUserId` or `telegram.allowlist`.
-3. Complete `/telegram connect` once.
-4. Send a message to your Telegram bot.
-5. Let the local Reasonix session keep running.
-6. Continue replies, approvals, and follow-up interactions from Telegram when needed.
-
-Telegram extends the current session. It does not replace `chat` or `code`.
-
-## Security notes
-
- Access is fail-closed. With no owner or allowlist, the channel does not start.
- Unauthorized senders and button presses are ignored.
- Confirmation buttons are bound to the current Telegram confirmation message, so stale buttons from older confirmations cannot approve newer requests.
- Authorized users are rate-limited before their messages reach the agent prompt path.
-
-## Troubleshooting
-
-### `/telegram connect` fails with an access control error
-
-Configure at least one allowed Telegram user:
-
-~~~json
-{
-  "telegram": {
-    "ownerUserId": "123456789"
-  }
-}
-~~~
-
-or:
-
-~~~json
-{
-  "telegram": {
-    "allowlist": ["123456789", "987654321"]
-  }
-}
-~~~
-
-Then reconnect:
-
-~~~text
-/telegram connect
-~~~
-
-### `/telegram connect` fails with a token error
-
-Check these first:
-
- the token was copied exactly from BotFather
- there are no extra spaces or shell quoting mistakes
- the bot has not been deleted or regenerated in BotFather
-
-If needed, reconnect with an explicit token:
-
-~~~text
-/telegram connect <botToken>
-~~~
-
-### Telegram receives the message, but no reply comes back
-
-Check that the local Reasonix session is still running and the channel is still connected:
-
-~~~text
-/telegram status
-~~~
-
-### Telegram says another poller is active
-
-Only one long-polling process can run for a Telegram bot at a time. Stop the other Reasonix process or any other bot process using the same token, then reconnect.
-
-### `/telegram` commands do not exist in your installed package
-
-Your installed npm version is too old. Upgrade to a release that already includes Telegram support, or use the current repository `main` branch.

-# Telegram 连接指南
-
-Reasonix 可以把现有的 `chat` 或 `code` 会话延伸到 Telegram 上，作为远程通道使用。Telegram 扩展的是当前会话，不是独立的新运行模式。
-
-连接成功后，Telegram 可以：
-
- 把普通消息送进当前会话
- 接收支持 Telegram Markdown 渲染的助手回复
- 用内联按钮继续确认、选择、checkpoint、plan 这类二次交互
- 把 Reasonix slash 命令注册成 Telegram bot command
-
-## 开始前先准备
-
-请先确认：
-
- 使用的是已经包含 Telegram 支持的较新 Reasonix 版本
- 已经有 Telegram 账号
- 已经从 BotFather 拿到 Telegram bot token
- 已经知道允许驱动 Reasonix 的 Telegram 数字用户 id
-
-注意：
-
- Telegram 默认 fail-closed：没有配置 `telegram.ownerUserId` 或 `telegram.allowlist` 时，通道会拒绝启动
- bot token 要妥善保管，不要公开
- 只允许你信任的 Telegram 用户驱动这个代码执行 bot
-
-## 获取 Telegram bot token
-
-BotFather 的界面可能会变化，但通常流程是：
-
-1. 在 Telegram 中打开 `@BotFather`
-2. 发送 `/newbot`
-3. 按提示填写 bot 名称和 username
-4. 复制 BotFather 返回的 bot token
-
-## 获取 Telegram 用户 id
-
-Reasonix 的访问控制使用 Telegram 数字用户 id，不使用 `@username`。
-
-常见获取方式：
-
- 给 `@userinfobot` 这类辅助 bot 发消息查看
- 给自己的 bot 发一条消息后，通过 Telegram `getUpdates` API 查看
- 从你信任的自有 bot 工具里读取
-
-请把这个 id 保存为 `telegram.ownerUserId`，或加入 `telegram.allowlist`。
-
-## 在 CLI 里连接
-
-先启动一个会话：
-
-~~~bash
-reasonix code
-# 或
-reasonix chat
-~~~
-
-连接前先配置访问控制。例如编辑 `~/.reasonix/config.json`：
-
-~~~json
-{
-  "telegram": {
-    "ownerUserId": "123456789"
-  }
-}
-~~~
-
-然后运行：
-
-~~~text
-/telegram connect
-~~~
-
-首次连接时会这样引导：
-
-1. 在当前 TUI 里提示你输入 Telegram bot token
-2. 输入 `/cancel` 可以取消
-3. 连接成功后，Reasonix 会保存 token 并启用后续自动启动
-
-如果本地已经保存过 token，`/telegram connect` 会直接复用。
-
-也可以直接一次性传参：
-
-~~~text
-/telegram connect <botToken>
-~~~
-
-其他相关命令：
-
- `/telegram status`
- `/telegram disconnect`
-
-第一次连接成功后，只要 Telegram 保持启用，后续 `chat` 和 `code` 会话都会自动启动 Telegram 通道。
-
-## 环境变量
-
-也可以用环境变量配置 Telegram：
-
-~~~bash
-TELEGRAM_BOT_TOKEN=123456:botfather-token
-TELEGRAM_OWNER_USER_ID=123456789
-TELEGRAM_ALLOWLIST=123456789,987654321
-~~~
-
-环境变量会覆盖本地保存的 token 和访问控制配置。`TELEGRAM_ALLOWLIST` 支持用逗号或空白分隔多个 id。
-
-## 典型使用方式
-
-1. 启动 `reasonix code` 或 `reasonix chat`
-2. 配置 `telegram.ownerUserId` 或 `telegram.allowlist`
-3. 完成一次 `/telegram connect`
-4. 从 Telegram 给 bot 发一条消息
-5. 本地 Reasonix 会话继续运行
-6. 需要时直接在 Telegram 里继续回复、确认或选择
-
-Telegram 只是扩展当前会话，不替代 `chat` 或 `code`。
-
-## 安全说明
-
- 访问控制默认 fail-closed；没有 owner 或 allowlist 时通道不会启动。
- 未授权用户的消息和按钮点击都会被忽略。
- 确认按钮会绑定到当前 Telegram 确认消息，旧确认里的按钮不能批准新的请求。
- 授权用户的消息在进入 agent prompt 路径前会被限流。
-
-## 排障
-
-### `/telegram connect` 报访问控制错误
-
-至少配置一个允许访问的 Telegram 用户：
-
-~~~json
-{
-  "telegram": {
-    "ownerUserId": "123456789"
-  }
-}
-~~~
-
-或者：
-
-~~~json
-{
-  "telegram": {
-    "allowlist": ["123456789", "987654321"]
-  }
-}
-~~~
-
-然后重新连接：
-
-~~~text
-/telegram connect
-~~~
-
-### `/telegram connect` 报 token 错误
-
-优先检查：
-
- token 是否完整复制自 BotFather
- 是否多了空格或 shell 引号问题
- BotFather 里这个 bot 是否已删除或重新生成 token
-
-必要时可以直接显式传参重试：
-
-~~~text
-/telegram connect <botToken>
-~~~
-
-### Telegram 能收到消息，但没有后续回复
-
-先确认本地 Reasonix 会话还在运行，而且 Telegram 通道仍然在线：
-
-~~~text
-/telegram status
-~~~
-
-### Telegram 提示已有另一个 poller
-
-同一个 Telegram bot 同一时间只能有一个 long-polling 进程。请停止其他使用同一个 token 的 Reasonix 进程或 bot 进程，然后重新连接。
-
-### 已安装的 npm 版本里没有 `/telegram` 命令
-
-说明本地包版本太旧。请升级到已经包含 Telegram 支持的发行版，或者直接使用仓库最新 `main` 分支。
