Subject: [PATCH 10/43] feat: session goals - server-driven goal loop with
 independent small-model audit (#2148)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Arm the target button in the composer and the next prompt becomes a goal:
the server keeps the session working toward it (idle tick -> small-model
audit -> continuation) until the objective is verifiably complete, blocked,
or out of budget — even with the UI closed.

Server (packages/web/server/lib/session-goal):
- event-driven loop on the global SSE hub; goal state lives in
  session.metadata.openchamber.goal (merge-safe patches, stale-write guard
  by goal id), so it survives restarts and syncs to every client for free
- the small-model audit (objective + last assistant turn only, language
  pinned to the objective) is the sole termination authority; blocked needs
  3 consecutive verdicts, audit outages tolerate one unaudited continuation
  then stop the goal as resumable-blocked
- hard stops: optional token budget, auto-continuation cap (Resume grants a
  fresh allowance), turn errors; user abort pauses the goal instead of
  blocking it, and resuming over an aborted tail nudges immediately
- token accounting as a snapshot of the latest turn (input + cache.read +
  output), goal-relative via a creation baseline and segmented across
  compactions; a compaction summary skips the audit and continues
- continuations reuse the session's own provider/model/agent/variant

UI:
- three-mode target button (arm / disarm / manage dialog), informational
  goal strip with inline pause/resume and an Evaluating indicator, sidebar
  state glyph, objective length counter (2000-char server clamp),
  read-only completed goals
- goal entry points: composer (sessions and drafts), start-new-session-
  from-answer dialog, plan implement dialog (plan content becomes the
  objective), scheduled tasks (Run as goal + budget)
- Settings -> Chat -> Goal: feature toggle + default token budget with
  three-layer parity (web server, client persistence, VS Code bridge);
  VS Code renders goal state but hides the entry points (the loop runs in
  the web server only)

Notifications: per-turn "ready" notifications are suppressed while a goal
is active; settling sends one final notification (desktop, web-push, APNs
generic titles with the session name as body) honoring the completion
toggle. Error/question/permission notifications are untouched.

Docs: user guide (session-goals) in all 9 locales + sidebar entry,
scheduled-tasks cross-reference, server module DOCUMENTATION.md.

+title: Objetivos de sesión
+description: Convierte un prompt en un objetivo hacia el que el agente trabaja automáticamente.
+---
+
+# Objetivos de sesión
+
+Un objetivo convierte un solo prompt en una línea de meta. En lugar de empujar al agente con "continúa" tras cada respuesta, defines el objetivo una vez — y OpenChamber mantiene la sesión trabajando hacia él automáticamente, comprobando el progreso con un auditor independiente después de cada turno. Sigue funcionando incluso mientras no estás.
+
+## Iniciar un objetivo
+
+1. Pulsa el botón de diana en el compositor. Se ilumina — el modo objetivo está armado.
+2. Escribe tu prompt y envíalo. Ese mensaje se convierte en el objetivo.
+
+Funciona igual en una sesión existente y en un borrador de sesión nueva: arma la diana, escribe el primer mensaje, envía — la nueva sesión arranca con el objetivo ya activo.
+
+### Más formas de iniciar un objetivo
+
+- **Desde una respuesta del agente**: en el diálogo "Start new session from this answer", marca **Ejecutar como objetivo** — la respuesta se entrega como una tarea que la nueva sesión ejecuta hasta completarla (combínalo con **Create worktree** para una ejecución aislada).
+- **Desde un plan**: al implementar un plan guardado en una sesión o worktree nuevos, marca **Ejecutar como objetivo** en el diálogo. El objetivo lleva el contenido del plan, así que el auditor juzga el progreso contra el plan real.
+- **Según un horario**: marca **Ejecutar como objetivo** en una [tarea programada](/scheduled-tasks/) para que las ejecuciones recurrentes persigan su prompt hasta completarlo.
+
+## Escribe un objetivo autocontenido
+
+El auditor de progreso solo ve tu objetivo y la última respuesta del agente — no el historial del chat. Redacta el mensaje-objetivo de forma que alguien sin el contexto de la conversación entienda cómo es el estado final.
+
+- Bien: "Añade tests para el módulo de exportación y haz que toda la suite pase."
+- No tan bien: "Arréglalo" o "Continúa con esa idea."
+
+Para pequeños ajustes contextuales no necesitas un objetivo — envía un mensaje normal.
+
+## Cómo funciona
+
+Cuando el agente se detiene y la sesión queda en silencio un momento, OpenChamber:
+
+1. Pide a un modelo pequeño y barato que audite el último turno contra el objetivo: ¿seguir, hecho o atascado?
+2. Si el veredicto es "seguir", envía un prompt de continuación y el agente retoma el trabajo.
+3. Si el objetivo se ha logrado de forma verificable, el objetivo se completa y recibes una notificación.
+4. Si el agente está realmente atascado (necesita tu intervención), el objetivo se detiene como bloqueado — pero solo después de que el auditor lo diga tres veces seguidas, así que un tropiezo puntual nunca termina el objetivo.
+
+También hay topes de seguridad: un presupuesto de tokens opcional, un límite de continuaciones automáticas y una parada ante errores de turno. Si el contexto de la sesión se compacta a mitad del trabajo, el objetivo simplemente continúa — chocar con la ventana de contexto es prueba de que el trabajo no había terminado.
+
+### Detener y reanudar
+
+- El **botón de detener** aborta el turno en curso y pausa el objetivo — tu "para" explícito siempre gana al bucle.
+- **Pausar** en la franja del objetivo hace lo mismo desde el otro lado: pausa el objetivo y detiene el turno en curso.
+- Mientras está pausado, chatea con normalidad — el bucle no interfiere.
+- **Reanudar** rearma el bucle: en una sesión inactiva el empujón de continuación sale de inmediato; si el agente está trabajando, el bucle se reengancha en su siguiente pausa.
+
+## Observar y gestionar
+
+- La franja sobre el compositor muestra la última nota de progreso, el estado y el uso de tokens, con un botón de pausar/reanudar integrado. Cuando el agente se ha detenido y el objetivo sigue activo, la franja muestra un **Evaluando…** giratorio — es la ventana de silencio y la auditoría en marcha.
+- El botón de diana permanece encendido mientras el objetivo corre (azul), se vuelve verde al completarse y rojo cuando está bloqueado o sin presupuesto. Púlsalo para abrir el diálogo del objetivo: edita el objetivo o el presupuesto, o elimínalo. Un objetivo completado es de solo lectura — elimínalo y arma uno nuevo.
+- En la barra lateral de sesiones aparece una pequeña diana junto a la fecha de la sesión, coloreada según el estado del objetivo.
+
+## Notificaciones
+
+Mientras un objetivo está activo, las notificaciones por turno de "agente listo" se suprimen — solo harían eco de las continuaciones del propio bucle. Cuando el objetivo se resuelve (completado, bloqueado o presupuesto alcanzado) recibes una única notificación final, en el escritorio y como push móvil. Obedece el mismo ajuste de "notificar al completar"; las solicitudes de permisos, las preguntas y las notificaciones de error siguen funcionando con normalidad.
+
+## Presupuesto de tokens
+
+En **Ajustes → Chat → Objetivo** puedes definir un presupuesto de tokens predeterminado para nuevos objetivos. Al alcanzarlo, el objetivo se detiene como "presupuesto alcanzado" en lugar de gastar más — puedes subir el presupuesto y reanudar desde el diálogo del objetivo.
+
+## Ten en cuenta
+
+- El bucle del objetivo corre en el servidor de OpenChamber, no en tu pestaña del navegador. Cierra la pestaña, bloquea el teléfono — el agente sigue trabajando y recibirás una notificación cuando el objetivo termine. El servidor (app de escritorio o proceso `openchamber`) debe seguir en marcha.
+- Los objetivos usan el proveedor y modelo de tu propia sesión, incluidas las llamadas del auditor — nada sale hacia proveedores que no uses ya.
+- Un objetivo por sesión a la vez.

+title: Objectifs de session
+description: Transformez un prompt en objectif vers lequel l'agent travaille automatiquement.
+---
+
+# Objectifs de session
+
+Un objectif transforme un seul prompt en ligne d'arrivée. Au lieu de relancer l'agent avec « continue » après chaque réponse, vous définissez l'objectif une fois — et OpenChamber fait travailler la session vers lui automatiquement, en vérifiant la progression avec un auditeur indépendant après chaque tour. Le travail continue même en votre absence.
+
+## Démarrer un objectif
+
+1. Appuyez sur le bouton cible du composeur. Il s'allume — le mode objectif est armé.
+2. Écrivez votre prompt et envoyez-le. Ce message devient l'objectif.
+
+Cela fonctionne aussi bien dans une session existante que dans un brouillon de nouvelle session : armez la cible, écrivez le premier message, envoyez — la nouvelle session démarre avec l'objectif déjà actif.
+
+### D'autres façons de démarrer un objectif
+
+- **Depuis une réponse de l'agent** : dans le dialogue « Start new session from this answer », cochez **Exécuter comme objectif** — la réponse est transmise comme une mission que la nouvelle session exécute jusqu'au bout (combinez avec **Create worktree** pour une exécution isolée).
+- **Depuis un plan** : en implémentant un plan enregistré dans une nouvelle session ou un worktree, cochez **Exécuter comme objectif** dans le dialogue. L'objectif porte le contenu du plan, l'auditeur juge donc la progression par rapport au plan réel.
+- **Selon un horaire** : cochez **Exécuter comme objectif** sur une [tâche planifiée](/scheduled-tasks/) pour que les exécutions récurrentes poursuivent leur prompt jusqu'au bout.
+
+## Rédigez un objectif autonome
+
+L'auditeur de progression ne voit que votre objectif et la dernière réponse de l'agent — pas l'historique du chat. Formulez donc le message-objectif de sorte qu'une personne sans le contexte de la conversation comprenne à quoi ressemble l'état final.
+
+- Bien : « Ajoute des tests pour le module d'export et fais passer toute la suite de tests. »
+- Moins bien : « Corrige ça » ou « Continue sur cette idée. »
+
+Pour de petits ajustements contextuels, pas besoin d'objectif — envoyez un message normal.
+
+## Comment ça marche
+
+Quand l'agent s'arrête et que la session reste calme un instant, OpenChamber :
+
+1. Demande à un petit modèle économique d'auditer le dernier tour par rapport à l'objectif : continuer, terminé ou bloqué ?
+2. Si le verdict est « continuer », il envoie un prompt de continuation et l'agent reprend le travail.
+3. Si l'objectif est atteint de manière vérifiable, l'objectif se termine et vous recevez une notification.
+4. Si l'agent est réellement bloqué (il a besoin de vous), l'objectif s'arrête comme bloqué — mais seulement après que l'auditeur l'a dit trois fois de suite ; un accroc ponctuel ne termine jamais l'objectif.
+
+Il y a aussi des garde-fous : un budget de tokens optionnel, un plafond de continuations automatiques et un arrêt en cas d'erreur de tour. Si le contexte de la session est compacté en plein travail, l'objectif continue simplement — heurter la fenêtre de contexte prouve que le travail n'était pas fini.
+
+### Arrêter et reprendre
+
+- Le **bouton stop** interrompt le tour en cours et met l'objectif en pause — votre « stop » explicite l'emporte toujours sur la boucle.
+- **Pause** sur la bande de l'objectif fait la même chose dans l'autre sens : elle met l'objectif en pause et arrête le tour en cours.
+- Pendant la pause, discutez normalement — la boucle reste à l'écart.
+- **Reprendre** réarme la boucle : sur une session inactive, la relance part immédiatement ; si l'agent est en train de travailler, la boucle se raccroche silencieusement à sa prochaine pause.
+
+## Suivre et gérer
+
+- La bande au-dessus du composeur affiche la dernière note de progression, le statut et l'usage de tokens, avec un bouton pause/reprise intégré. Quand l'agent s'est arrêté et que l'objectif est actif, la bande affiche un **Évaluation…** animé — c'est la fenêtre de calme et l'audit en cours.
+- Le bouton cible reste allumé tant que l'objectif tourne (bleu), passe au vert à la fin et au rouge s'il est bloqué ou à court de budget. Appuyez dessus pour ouvrir le dialogue de l'objectif : modifier l'objectif ou le budget, ou le supprimer. Un objectif terminé est en lecture seule — supprimez-le, puis armez-en un nouveau.
+- Dans la barre latérale des sessions, une petite cible apparaît à côté de la date de la session, colorée selon l'état de l'objectif.
+
+## Notifications
+
+Tant qu'un objectif est actif, les notifications « agent prêt » à chaque tour sont supprimées — elles ne feraient qu'écho aux continuations de la boucle elle-même. Quand l'objectif se règle (terminé, bloqué ou budget atteint), vous recevez une seule notification finale, sur le bureau et en push mobile. Elle respecte le même réglage « notifier à la fin » ; les demandes de permission, les questions et les notifications d'erreur continuent de fonctionner normalement.
+
+## Budget de tokens
+
+Dans **Paramètres → Chat → Objectif**, vous pouvez définir un budget de tokens par défaut pour les nouveaux objectifs. Quand un objectif atteint son budget, il s'arrête en « budget atteint » au lieu de dépenser plus — vous pouvez augmenter le budget et reprendre depuis le dialogue de l'objectif.
+
+## À garder en tête
+
+- La boucle d'objectif tourne dans le serveur OpenChamber, pas dans votre onglet de navigateur. Fermez l'onglet, verrouillez le téléphone — l'agent continue, et vous recevez une notification quand l'objectif se termine. Le serveur (app de bureau ou processus `openchamber`) doit rester lancé.
+- Les objectifs utilisent le fournisseur et le modèle de votre propre session, y compris pour les appels de l'auditeur — rien ne part vers des fournisseurs que vous n'utilisez pas déjà.
+- Un objectif par session à la fois.

+title: セッションゴール
+description: プロンプトをゴールに変え、エージェントが自動的に取り組み続けます。
+---
+
+# セッションゴール
+
+ゴールは、1つのプロンプトをゴールラインに変えます。返信のたびに「続けて」と促す代わりに、ゴールを一度設定するだけ — OpenChamber がセッションを自動的にゴールへ向かわせ、各ターンの後に独立した監査モデルで進捗を確認します。離席中でも動き続けます。
+
+## ゴールを開始する
+
+1. コンポーザーのターゲットボタンを押します。点灯すればゴールモードが準備完了です。
+2. プロンプトを書いて送信します。そのメッセージがゴールの目標になります。
+
+既存のセッションでも新規セッションの下書きでも同じように機能します。ターゲットを有効にして最初のメッセージを書いて送信すれば、新しいセッションは最初からゴールが有効な状態で始まります。
+
+### ゴールを開始する他の方法
+
+- **エージェントの返信から**：「Start new session from this answer」ダイアログで **ゴールとして実行** にチェック — 返信が課題として引き継がれ、新しいセッションが完了まで実行します（**Create worktree** と組み合わせれば隔離された実行になります）。
+- **プランから**：保存したプランを新しいセッションや worktree で実装するとき、ダイアログの **ゴールとして実行** にチェック。ゴールの目標にはプランの内容が入るため、監査はプランそのものに照らして進捗を判定します。
+- **スケジュールで**：[スケジュールタスク](/scheduled-tasks/)の **ゴールとして実行** にチェックすると、定期実行がプロンプトを完了まで追求します。
+
+## 自己完結した目標を書く
+
+進捗の監査モデルが見るのは、あなたの目標とエージェントの最新の返信だけです — チャット履歴は見ません。会話の文脈を知らない人でも完成状態がわかるように、ゴールのメッセージを書いてください。
+
+- 良い例：「エクスポートモジュールのテストを追加し、テストスイート全体を通るようにして。」
+- 良くない例：「直して」「さっきのアイデアで続けて」
+
+ちょっとした文脈依存の指示にはゴールは不要です — 普通のメッセージを送りましょう。
+
+## 仕組み
+
+エージェントが停止してセッションがしばらく静かになると、OpenChamber は：
+
+1. 小型で安価なモデルに、最新のターンを目標と照らして監査させます：続行、完了、それとも行き詰まり？
+2. 判定が「続行」なら、継続プロンプトを送り、エージェントが作業を再開します。
+3. 目標が検証可能な形で達成されていればゴールは完了し、通知が届きます。
+4. エージェントが本当に行き詰まっている（あなたの入力が必要な）場合、ゴールはブロックとして停止します — ただし監査が3回連続でそう判定した場合のみ。一度のつまずきでゴールが終わることはありません。
+
+ハードな安全装置もあります：オプションのトークン予算、自動継続の上限、ターンエラー時の停止です。作業中にセッションのコンテキストが圧縮されても、ゴールはそのまま続行します — コンテキストウィンドウに達したこと自体が、作業が終わっていない証拠だからです。
+
+### 停止と再開
+
+- **停止ボタン**は実行中のターンを中断し、ゴールを一時停止します — あなたの明示的な「止めて」は常にループより優先されます。
+- ストリップの**一時停止**は逆方向から同じことをします：ゴールを一時停止し、実行中のターンを止めます。
+- 一時停止中は普通にチャットできます — ループは邪魔をしません。
+- **再開**はループを再始動します：アイドルなセッションでは継続プロンプトが即座に送られ、エージェントが作業中なら次の停止時にループが静かに再接続します。
+
+## 確認と管理
+
+- コンポーザー上部のストリップに、最新の進捗メモ、ステータス、トークン使用量が表示され、一時停止/再開ボタンも組み込まれています。エージェントが停止していてゴールがアクティブなときは、回転する**評価中…**が表示されます — 静止ウィンドウと監査が動いている印です。
+- ターゲットボタンはゴール実行中は点灯し（青）、完了で緑、ブロックや予算切れで赤になります。押すとゴールのダイアログが開き、目標や予算の編集、ゴールの削除ができます。完了したゴールは読み取り専用です — 削除してから新しいゴールを開始してください。
+- セッションサイドバーでは、セッションの日付の横にゴールの状態色の小さなターゲットが表示されます。
+
+## 通知
+
+ゴールがアクティブな間、ターンごとの「エージェント準備完了」通知は抑制されます — ループ自身の継続をなぞるだけだからです。ゴールが確定すると（完了、ブロック、予算到達）、代わりに最終通知が1件、デスクトップとモバイルプッシュで届きます。「完了時に通知」と同じ設定に従います。権限リクエスト、質問、エラー通知は通常どおり機能し続けます。
+
+## トークン予算
+
+**設定 → チャット → ゴール** で、新しいゴールのデフォルトトークン予算を設定できます。予算に達するとゴールは「予算上限に到達」として停止し、それ以上消費しません — 予算を上げてゴールのダイアログから再開できます。
+
+## 留意点
+
+- ゴールのループはブラウザのタブではなく OpenChamber サーバーで動きます。タブを閉じても、スマホをロックしても — エージェントは働き続け、ゴールが確定すると通知が届きます。サーバー（デスクトップアプリまたは `openchamber` プロセス）は起動したままにしてください。
+- ゴールはセッション自身のプロバイダーとモデルを使います。監査の呼び出しも同様です — 既に使っているプロバイダーの外にデータが出ることはありません。
+- ゴールは1セッションにつき同時に1つです。

+title: 세션 목표
+description: 프롬프트를 목표로 바꾸면 에이전트가 자동으로 계속 작업합니다.
+---
+
+# 세션 목표
+
+목표는 하나의 프롬프트를 결승선으로 바꿉니다. 답변이 올 때마다 "계속해"라고 재촉하는 대신 목표를 한 번만 설정하면 — OpenChamber가 세션을 자동으로 목표를 향해 이끌고, 매 턴이 끝날 때마다 독립적인 감사 모델로 진행 상황을 확인합니다. 자리를 비운 동안에도 계속 작동합니다.
+
+## 목표 시작하기
+
+1. 컴포저의 타깃 버튼을 누릅니다. 불이 켜지면 목표 모드가 준비된 것입니다.
+2. 프롬프트를 작성하고 전송합니다. 그 메시지가 목표가 됩니다.
+
+기존 세션과 새 세션 초안 모두에서 동일하게 작동합니다. 타깃을 켜고 첫 메시지를 작성해 전송하면 — 새 세션이 목표가 이미 활성화된 상태로 시작됩니다.
+
+### 목표를 시작하는 다른 방법
+
+- **에이전트의 답변에서**: "Start new session from this answer" 대화 상자에서 **목표로 실행**을 체크 — 답변이 과제로 넘겨져 새 세션이 완료까지 실행합니다(**Create worktree**와 결합하면 격리된 실행이 됩니다).
+- **계획에서**: 저장된 계획을 새 세션이나 worktree에서 구현할 때 대화 상자의 **목표로 실행**을 체크하세요. 목표에 계획 내용이 담기므로 감사가 실제 계획을 기준으로 진행 상황을 판단합니다.
+- **일정에 따라**: [예약 작업](/scheduled-tasks/)에서 **목표로 실행**을 체크하면 반복 실행이 프롬프트를 완료까지 추진합니다.
+
+## 자기 완결적인 목표 작성하기
+
+진행 감사 모델은 목표와 에이전트의 최신 답변만 봅니다 — 채팅 기록은 보지 않습니다. 따라서 대화 맥락을 모르는 사람도 완료 상태가 어떤 모습인지 이해할 수 있도록 목표 메시지를 작성하세요.
+
+- 좋은 예: "내보내기 모듈에 테스트를 추가하고 전체 테스트 스위트를 통과시켜."
+- 좋지 않은 예: "고쳐줘" 또는 "그 아이디어로 계속해."
+
+작은 맥락적 후속 지시에는 목표가 필요 없습니다 — 그냥 일반 메시지를 보내세요.
+
+## 작동 방식
+
+에이전트가 멈추고 세션이 잠시 조용해지면 OpenChamber는:
+
+1. 작고 저렴한 모델에게 최신 턴을 목표와 대조해 감사하게 합니다: 계속, 완료, 아니면 막힘?
+2. 판정이 "계속"이면 계속 프롬프트를 보내고 에이전트가 작업을 다시 시작합니다.
+3. 목표가 검증 가능하게 달성되면 목표가 완료되고 알림이 옵니다.
+4. 에이전트가 정말로 막혔다면(사용자의 입력이 필요하면) 목표는 차단됨으로 멈춥니다 — 단, 감사가 세 번 연속 그렇게 판정한 후에만요. 한 번의 걸림돌로 목표가 끝나는 일은 없습니다.
+
+강제 안전장치도 있습니다: 선택적 토큰 예산, 자동 계속 횟수 상한, 턴 오류 시 중지. 작업 도중 세션 컨텍스트가 압축되어도 목표는 그냥 계속됩니다 — 컨텍스트 창에 부딪혔다는 것 자체가 작업이 끝나지 않았다는 증거이기 때문입니다.
+
+### 중지와 재개
+
+- **중지 버튼**은 실행 중인 턴을 중단하고 목표를 일시 중지합니다 — 당신의 명시적인 "멈춰"가 항상 루프보다 우선합니다.
+- 스트립의 **일시 중지**는 반대 방향에서 같은 일을 합니다: 목표를 일시 중지하고 실행 중인 턴을 멈춥니다.
+- 일시 중지 중에는 평소처럼 채팅하세요 — 루프가 끼어들지 않습니다.
+- **재개**는 루프를 다시 켭니다: 유휴 세션에서는 계속 프롬프트가 즉시 나가고, 에이전트가 작업 중이라면 다음 멈춤에서 루프가 조용히 다시 붙습니다.
+
+## 확인 및 관리
+
+- 컴포저 위의 스트립에 최신 진행 메모, 상태, 토큰 사용량이 표시되며, 일시 중지/재개 버튼이 함께 있습니다. 에이전트가 멈췄는데 목표가 활성 상태라면 스트립에 회전하는 **평가 중…**이 표시됩니다 — 조용한 대기 시간과 감사가 진행 중이라는 뜻입니다.
+- 타깃 버튼은 목표가 실행 중일 때 켜져 있고(파란색), 완료되면 초록색, 차단되거나 예산이 소진되면 빨간색이 됩니다. 누르면 목표 대화 상자가 열립니다: 목표나 예산을 편집하거나 목표를 제거하세요. 완료된 목표는 읽기 전용입니다 — 제거한 후 새 목표를 시작하세요.
+- 세션 사이드바에서 세션 날짜 옆에 목표 상태 색상의 작은 타깃이 나타납니다.
+
+## 알림
+
+목표가 활성 상태인 동안 턴마다 오는 "에이전트 준비 완료" 알림은 억제됩니다 — 루프 자체의 계속 실행을 되풀이할 뿐이기 때문입니다. 목표가 확정되면(완료, 차단, 예산 도달) 대신 최종 알림 하나가 데스크톱과 모바일 푸시로 옵니다. "완료 시 알림"과 같은 설정을 따릅니다. 권한 요청, 질문, 오류 알림은 평소처럼 계속 작동합니다.
+
+## 토큰 예산
+
+**설정 → 채팅 → 목표**에서 새 목표의 기본 토큰 예산을 설정할 수 있습니다. 목표가 예산에 도달하면 더 소비하지 않고 "예산 도달"로 멈춥니다 — 예산을 올리고 목표 대화 상자에서 재개할 수 있습니다.
+
+## 유의 사항
+
+- 목표 루프는 브라우저 탭이 아니라 OpenChamber 서버에서 실행됩니다. 탭을 닫든 휴대폰을 잠그든 — 에이전트는 계속 일하고, 목표가 확정되면 알림이 옵니다. 서버(데스크톱 앱 또는 `openchamber` 프로세스)는 계속 실행 중이어야 합니다.
+- 목표는 감사 호출을 포함해 세션 자체의 프로바이더와 모델을 사용합니다 — 이미 사용 중인 프로바이더 밖으로 나가는 것은 없습니다.
+- 세션당 목표는 한 번에 하나입니다.

+title: Cele sesji
+description: Zamień prompt w cel, nad którym agent pracuje automatycznie.
+---
+
+# Cele sesji
+
+Cel zamienia jeden prompt w linię mety. Zamiast popychać agenta słowem „kontynuuj" po każdej odpowiedzi, ustawiasz cel raz — a OpenChamber automatycznie prowadzi sesję w jego stronę, sprawdzając postęp niezależnym audytorem po każdej turze. Praca trwa nawet pod twoją nieobecność.
+
+## Rozpoczęcie celu
+
+1. Naciśnij przycisk celu (tarczę) w kompozytorze. Zapala się — tryb celu jest uzbrojony.
+2. Napisz prompt i wyślij. Ta wiadomość staje się treścią celu.
+
+Działa to tak samo w istniejącej sesji i w szkicu nowej: uzbrój tarczę, napisz pierwszą wiadomość, wyślij — nowa sesja startuje z już aktywnym celem.
+
+### Inne sposoby rozpoczęcia celu
+
+- **Z odpowiedzi agenta**: w oknie „Start new session from this answer" zaznacz **Uruchom jako cel** — odpowiedź zostaje przekazana jako zadanie, które nowa sesja wykonuje do końca (połącz z **Create worktree**, aby uzyskać izolowane uruchomienie).
+- **Z planu**: implementując zapisany plan w nowej sesji lub worktree, zaznacz **Uruchom jako cel** w oknie dialogowym. Treścią celu staje się zawartość planu, więc audytor ocenia postęp względem samego planu.
+- **Według harmonogramu**: zaznacz **Uruchom jako cel** w [zaplanowanym zadaniu](/scheduled-tasks/), aby cykliczne uruchomienia doprowadzały prompt do końca.
+
+## Formułuj cel samowystarczalnie
+
+Audytor postępu widzi tylko treść celu i ostatnią odpowiedź agenta — bez historii czatu. Sformułuj więc wiadomość-cel tak, aby osoba bez kontekstu rozmowy zrozumiała, jak wygląda stan końcowy.
+
+- Dobrze: „Dodaj testy dla modułu eksportu i doprowadź cały zestaw testów do zielonego stanu."
+- Słabiej: „Napraw to" albo „Kontynuuj z tamtym pomysłem."
+
+Do drobnych kontekstowych poleceń cel nie jest potrzebny — wyślij zwykłą wiadomość.
+

+
+1. Prosi mały, tani model o audyt ostatniej tury względem celu: kontynuować, gotowe czy utknięto?
+2. Jeśli werdykt to „kontynuować", wysyła prompt kontynuacji i agent wraca do pracy.
+3. Jeśli cel jest weryfikowalnie osiągnięty, cel się kończy, a ty dostajesz powiadomienie.
+4. Jeśli agent naprawdę utknął (potrzebuje twojego udziału), cel zatrzymuje się jako zablokowany — ale dopiero gdy audytor powie to trzy razy z rzędu, więc jednorazowa przeszkoda nigdy nie kończy celu.
+
+Są też twarde bezpieczniki: opcjonalny budżet tokenów, limit automatycznych kontynuacji i stop przy błędzie tury. Jeśli kontekst sesji zostanie skompaktowany w trakcie pracy, cel po prostu trwa dalej — uderzenie w okno kontekstu to dowód, że praca nie była skończona.
+
+### Zatrzymywanie i wznawianie
+
+- **Przycisk stop** przerywa bieżącą turę i wstrzymuje cel — twoje wyraźne „stop" zawsze wygrywa z pętlą.
+- **Wstrzymaj** na pasku celu robi to samo z drugiej strony: wstrzymuje cel i zatrzymuje bieżącą turę.
+- Podczas wstrzymania rozmawiaj normalnie — pętla nie przeszkadza.
+- **Wznów** ponownie uzbraja pętlę: w bezczynnej sesji zachęta do kontynuacji wychodzi natychmiast; jeśli agent akurat pracuje, pętla po cichu podłącza się przy jego następnej przerwie.
+
+## Podgląd i zarządzanie
+
+- Pasek nad kompozytorem pokazuje ostatnią notatkę postępu, status i zużycie tokenów, wraz z przyciskiem wstrzymaj/wznów. Gdy agent się zatrzymał, a cel jest aktywny, pasek pokazuje wirujące **Ocenianie…** — to okno ciszy i trwający audyt.
+- Przycisk-tarcza świeci, póki cel działa (niebieski), zielenieje po ukończeniu, a czerwienieje przy zablokowaniu lub wyczerpaniu budżetu. Naciśnij go, aby otworzyć okno celu: edytuj treść lub budżet albo usuń cel. Ukończony cel jest tylko do odczytu — usuń go, a potem uzbrój nowy.
+- W panelu bocznym sesji obok daty sesji pojawia się mała tarcza w kolorze stanu celu.
+
+## Powiadomienia
+
+Póki cel jest aktywny, powiadomienia „agent gotowy" po każdej turze są wyciszone — powtarzałyby tylko kontynuacje samej pętli. Gdy cel się rozstrzygnie (ukończony, zablokowany lub budżet wyczerpany), dostajesz zamiast tego jedno końcowe powiadomienie — na desktopie i jako push mobilny. Respektuje to samo ustawienie „powiadamiaj o ukończeniu"; prośby o uprawnienia, pytania i powiadomienia o błędach działają jak zwykle.
+
+## Budżet tokenów
+
+W **Ustawienia → Czat → Cel** możesz ustawić domyślny budżet tokenów dla nowych celów. Po osiągnięciu budżetu cel zatrzymuje się jako „budżet wyczerpany" zamiast wydawać więcej — możesz podnieść budżet i wznowić z okna celu.
+
+## Miej na uwadze
+
+- Pętla celu działa na serwerze OpenChamber, nie w karcie przeglądarki. Zamknij kartę, zablokuj telefon — agent pracuje dalej, a gdy cel się rozstrzygnie, dostaniesz powiadomienie. Serwer (aplikacja desktopowa lub proces `openchamber`) musi pozostać uruchomiony.
+- Cele używają dostawcy i modelu twojej własnej sesji, łącznie z wywołaniami audytora — nic nie trafia do dostawców, których już nie używasz.
+- Jeden cel na sesję naraz.

+title: Objetivos de sessão
+description: Transforme um prompt em um objetivo no qual o agente trabalha automaticamente.
+---
+
+# Objetivos de sessão
+
+Um objetivo transforma um único prompt em uma linha de chegada. Em vez de cutucar o agente com "continua" após cada resposta, você define o objetivo uma vez — e o OpenChamber mantém a sessão trabalhando em direção a ele automaticamente, verificando o progresso com um auditor independente após cada turno. Continua rodando mesmo enquanto você está ausente.
+
+## Iniciar um objetivo
+
+1. Pressione o botão de alvo no compositor. Ele acende — o modo objetivo está armado.
+2. Escreva seu prompt e envie. Essa mensagem se torna o objetivo.
+
+Funciona igualmente em uma sessão existente e em um rascunho de sessão nova: arme o alvo, escreva a primeira mensagem, envie — a nova sessão começa com o objetivo já ativo.
+
+### Mais formas de iniciar um objetivo
+
+- **A partir de uma resposta do agente**: no diálogo "Start new session from this answer", marque **Executar como objetivo** — a resposta é entregue como uma tarefa que a nova sessão executa até concluir (combine com **Create worktree** para uma execução isolada).
+- **A partir de um plano**: ao implementar um plano salvo em uma sessão ou worktree novos, marque **Executar como objetivo** no diálogo. O objetivo carrega o conteúdo do plano, então o auditor julga o progresso contra o plano real.
+- **Em um cronograma**: marque **Executar como objetivo** em uma [tarefa agendada](/scheduled-tasks/) para que execuções recorrentes persigam o prompt até concluir.
+
+## Escreva um objetivo autocontido
+
+O auditor de progresso vê apenas o seu objetivo e a última resposta do agente — não o histórico do chat. Então formule a mensagem-objetivo de forma que alguém sem o contexto da conversa entenda como é o estado final.
+
+- Bom: "Adicione testes para o módulo de exportação e faça toda a suíte de testes passar."
+- Nem tanto: "Conserta isso" ou "Continua com aquela ideia."
+
+Para pequenos ajustes contextuais você não precisa de um objetivo — envie uma mensagem normal.
+
+## Como funciona
+
+Quando o agente para e a sessão fica quieta por um momento, o OpenChamber:
+
+1. Pede a um modelo pequeno e barato que audite o último turno contra o objetivo: continuar, pronto ou travado?
+2. Se o veredicto for "continuar", envia um prompt de continuação e o agente retoma o trabalho.
+3. Se o objetivo foi alcançado de forma verificável, o objetivo é concluído e você recebe uma notificação.
+4. Se o agente está realmente travado (precisa da sua participação), o objetivo para como bloqueado — mas só depois que o auditor disser isso três vezes seguidas, então um tropeço pontual nunca encerra o objetivo.
+
+Há também freios de segurança: um orçamento de tokens opcional, um teto de continuações automáticas e parada em erros de turno. Se o contexto da sessão for compactado no meio do trabalho, o objetivo simplesmente continua — bater na janela de contexto é prova de que o trabalho não tinha terminado.
+
+### Parar e retomar
+
+- O **botão de parar** aborta o turno em andamento e pausa o objetivo — o seu "para" explícito sempre vence o loop.
+- **Pausar** na faixa do objetivo faz o mesmo pelo outro lado: pausa o objetivo e para o turno em andamento.
+- Enquanto pausado, converse normalmente — o loop fica de fora.
+- **Retomar** rearma o loop: em uma sessão ociosa o empurrão de continuação sai imediatamente; se o agente estiver trabalhando, o loop se reconecta silenciosamente na próxima pausa dele.
+
+## Acompanhar e gerenciar
+
+- A faixa acima do compositor mostra a última nota de progresso, o status e o uso de tokens, com um botão de pausar/retomar integrado. Quando o agente parou e o objetivo está ativo, a faixa mostra um **Avaliando…** girando — é a janela de silêncio e a auditoria em andamento.
+- O botão de alvo fica aceso enquanto o objetivo roda (azul), fica verde ao concluir e vermelho quando bloqueado ou sem orçamento. Pressione-o para abrir o diálogo do objetivo: edite o objetivo ou o orçamento, ou remova-o. Um objetivo concluído é somente leitura — remova-o e arme um novo.
+- Na barra lateral de sessões, um pequeno alvo aparece ao lado da data da sessão, colorido pelo estado do objetivo.
+
+## Notificações
+
+Enquanto um objetivo está ativo, as notificações por turno de "agente pronto" são suprimidas — elas só ecoariam as continuações do próprio loop. Quando o objetivo se resolve (concluído, bloqueado ou orçamento atingido) você recebe uma única notificação final, no desktop e como push móvel. Ela obedece à mesma configuração de "notificar ao concluir"; solicitações de permissão, perguntas e notificações de erro continuam funcionando normalmente.
+
+## Orçamento de tokens
+
+Em **Configurações → Chat → Objetivo** você pode definir um orçamento de tokens padrão para novos objetivos. Quando um objetivo atinge o orçamento, ele para como "orçamento atingido" em vez de gastar mais — você pode aumentar o orçamento e retomar pelo diálogo do objetivo.
+
+## Tenha em mente
+
+- O loop do objetivo roda no servidor do OpenChamber, não na aba do navegador. Feche a aba, bloqueie o celular — o agente continua trabalhando, e você recebe uma notificação quando o objetivo se resolve. O servidor (app desktop ou processo `openchamber`) precisa continuar rodando.
+- Objetivos usam o provedor e o modelo da sua própria sessão, incluindo as chamadas do auditor — nada sai para provedores que você já não use.
+- Um objetivo por sessão de cada vez.

+title: Session Goals
+description: Turn a prompt into a goal the agent keeps working toward automatically.
+---
+
+# Session Goals
+
+A goal turns one prompt into a finish line. Instead of nudging the agent with "continue" after every reply, you set a goal once — and OpenChamber keeps the session working toward it automatically, checking progress with an independent auditor after every turn. It keeps running even while you are away.
+
+## Start a goal
+
+1. Press the target button in the composer. It lights up — goal mode is armed.
+2. Type your prompt and send it. That message becomes the goal's objective.
+
+This works in an existing session and in a new session draft alike: arm the target, write the first message, send — the new session starts with the goal already active.
+
+### More ways to start a goal
+
+- **From an agent's reply**: in the "Start new session from this answer" dialog, check **Run as goal** — the reply is handed over as an assignment the new session executes to completion (combine with **Create worktree** for an isolated run).
+- **From a plan**: when implementing a saved plan in a new session or worktree, check **Run as goal** in the dialog. The goal carries the plan content as its objective, so the auditor judges progress against the actual plan.
+- **On a schedule**: check **Run as goal** on a [scheduled task](/scheduled-tasks/) to make recurring runs pursue their prompt to completion.
+
+## Write a self-contained objective
+
+The progress auditor sees only your objective and the agent's latest reply — not the chat history. So phrase the goal message so that someone without the conversation context would understand what the finished state looks like.
+
+- Good: "Add tests for the export module and make the whole test suite pass."
+- Not so good: "Fix it" or "Continue with that idea."
+
+For small contextual follow-ups you don't need a goal — just send a normal message.
+
+## How it works
+
+After the agent stops and the session stays quiet for a moment, OpenChamber:
+
+1. Asks a small, cheap model to audit the latest turn against the objective: keep going, done, or stuck?
+2. If the verdict is "keep going", it sends a continuation prompt and the agent picks the work back up.
+3. If the objective is verifiably achieved, the goal completes and you get a notification.
+4. If the agent is genuinely stuck (needs your input), the goal stops as blocked — but only after the auditor says so three times in a row, so a one-off snag never ends the goal.
+
+There are hard safety stops too: an optional token budget, a cap on automatic continuations, and a stop on turn errors. If the session's context gets compacted mid-work, the goal simply continues — running into the context window is proof the work wasn't finished.
+
+### Stopping and resuming
+
+- The **stop button** aborts the running turn and pauses the goal — your explicit "stop" always wins over the loop.
+- **Pause** on the goal strip does the same from the other direction: it pauses the goal and stops the running turn.
+- While paused, chat normally — the loop stays out of the way.
+- **Resume** re-arms the loop: on an idle session the continuation nudge goes out immediately; if the agent happens to be working, the loop silently re-attaches at its next pause.
+
+## Watch and manage
+
+- The strip above the composer shows the goal's latest progress note, status, and token usage, with an inline pause/resume button. When the agent has stopped and the goal is active, the strip shows a spinning **Evaluating…** — that's the quiet window and the audit running.
+- The target button stays lit while the goal runs (blue), turns green on completion, and red when blocked or out of budget. Press it to open the goal dialog: edit the objective or budget, or remove the goal. A completed goal is read-only — remove it, then arm a new one.
+- In the session sidebar, a small target appears next to the session date, colored by the goal's state.
+
+## Notifications
+
+While a goal is active, the per-turn "agent is ready" notifications are suppressed — they would just echo the goal loop's own continuations. When the goal settles (complete, blocked, or budget reached) you get one final notification instead, on desktop and as a mobile push. It obeys the same "notify on completion" setting; permission requests, questions, and error notifications keep working as usual throughout.
+
+## Token budget
+
+In **Settings → Chat → Goal** you can set a default token budget for new goals. When a goal reaches its budget it stops as "budget reached" instead of spending more — you can raise the budget and resume from the goal dialog.
+
+## Keep in mind
+
+- The goal loop runs in the OpenChamber server, not in your browser tab. Close the tab, lock the phone — the agent keeps working, and you get a notification when the goal settles. The server (desktop app or `openchamber` process) must stay running.
+- Goals use your session's own provider and model, including the auditor calls — nothing leaves the providers you already use.
+- One goal per session at a time.

+title: Цілі сесії
+description: Перетворіть промпт на ціль, до якої агент рухається автоматично.
+---
+
+# Цілі сесії
+
+Ціль перетворює один промпт на фінішну пряму. Замість підштовхувати агента словом «продовжуй» після кожної відповіді, ви ставите ціль один раз — і OpenChamber автоматично веде сесію до неї, перевіряючи прогрес незалежним аудитором після кожного ходу. Робота триває, навіть поки вас немає поруч.
+
+## Як розпочати ціль
+
+1. Натисніть кнопку-мішень у полі вводу. Вона засвітиться — режим цілі увімкнено.
+2. Напишіть промпт і надішліть. Це повідомлення стане формулюванням цілі.
+
+Це працює однаково і в наявній сесії, і в чернетці нової: увімкніть мішень, напишіть перше повідомлення, надішліть — нова сесія почнеться вже з активною ціллю.
+
+### Інші способи розпочати ціль
+
+- **З відповіді агента**: у діалозі «Start new session from this answer» позначте **Run as goal** — відповідь передається як завдання, яке нова сесія виконує до завершення (комбінуйте з **Create worktree** для ізольованого запуску).
+- **З плану**: виконуючи збережений план у новій сесії чи worktree, позначте **Run as goal** у діалозі. Формулюванням цілі стане зміст плану, тож аудитор судитиме прогрес за самим планом.
+- **За розкладом**: позначте **Run as goal** у [запланованому завданні](/scheduled-tasks/), щоб регулярні запуски доводили промпт до завершення.
+
+## Формулюйте ціль самодостатньо
+
+Аудитор прогресу бачить лише ваше формулювання цілі та останню відповідь агента — без історії чату. Тому пишіть повідомлення-ціль так, щоб людина без контексту розмови зрозуміла, як виглядає завершений стан.
+
+- Добре: «Додай тести для модуля експорту й доведи весь тестовий набір до зеленого стану.»
+- Не дуже: «Виправ це» або «Продовжуй з тією ідеєю.»
+
+Для дрібних контекстних уточнень ціль не потрібна — просто надішліть звичайне повідомлення.
+
+## Як це працює
+
+Коли агент зупиняється і сесія трохи затихає, OpenChamber:
+
+1. Просить малу, дешеву модель оцінити останній хід відносно цілі: продовжувати, готово чи глухий кут?
+2. Якщо вердикт «продовжувати» — надсилає промпт продовження, і агент береться за роботу знову.
+3. Якщо ціль перевірено досягнута — вона завершується, а ви отримуєте сповіщення.
+4. Якщо агент справді застряг (потрібна ваша участь), ціль зупиняється як заблокована — але лише після того, як аудитор скаже це тричі поспіль, тож разова заминка ніколи не завершує ціль.
+
+Є й жорсткі запобіжники: опційний бюджет токенів, ліміт автоматичних продовжень і зупинка при помилці ходу. Якщо контекст сесії стиснеться посеред роботи, ціль просто продовжиться — впертися у вікно контексту означає, що робота не завершена.
+
+### Зупинка і відновлення
+
+- **Кнопка стоп** обриває поточний хід і призупиняє ціль — ваше явне «стоп» завжди сильніше за цикл.
+- **Pause** на смужці цілі робить те саме з іншого боку: призупиняє ціль і зупиняє поточний хід.
+- Поки ціль на паузі, спілкуйтеся як завжди — цикл не втручається.
+- **Resume** знову вмикає цикл: на сесії у простої промпт продовження летить негайно; якщо агент саме працює — цикл тихо підхопиться на його наступній паузі.
+
+## Спостереження і керування
+
+- Смужка над полем вводу показує останню нотатку прогресу, статус і використання токенів, а також кнопку призупинення/відновлення. Коли агент зупинився, а ціль активна, смужка показує обертовий **Оцінювання…** — це вікно тиші та робота аудитора.
+- Кнопка-мішень світиться, поки ціль працює (синім), стає зеленою при завершенні та червоною, коли ціль заблокована чи вичерпала бюджет. Натисніть її, щоб відкрити діалог цілі: відредагувати формулювання чи бюджет або видалити ціль. Завершена ціль лише для читання — видаліть її, а тоді вмикайте нову.
+- У бічній панелі сесій біля дати сесії з'являється маленька мішень, забарвлена за станом цілі.
+
+## Сповіщення
+
+Поки ціль активна, сповіщення «агент готовий» після кожного ходу придушені — вони лише повторювали б продовження самого циклу. Коли ціль завершується (готово, заблоковано чи вичерпано бюджет), натомість приходить одне фінальне сповіщення — на десктопі та мобільним пушем. Воно поважає те саме налаштування «сповіщати про завершення»; запити дозволів, питання та сповіщення про помилки працюють як завжди.
+
+## Бюджет токенів
+
+У **Налаштування → Чат → Ціль** можна задати типовий бюджет токенів для нових цілей. Досягнувши бюджету, ціль зупиняється як «бюджет вичерпано» замість витрачати більше — можна підняти бюджет і відновити її з діалогу цілі.
+
+## Варто знати
+
+- Цикл цілі працює в сервері OpenChamber, а не у вкладці браузера. Закрийте вкладку, заблокуйте телефон — агент працює далі, а коли ціль завершиться, прийде сповіщення. Сервер (десктопна апка або процес `openchamber`) має залишатися запущеним.
+- Цілі використовують провайдера й модель самої сесії, включно з викликами аудитора — нічого не йде до провайдерів, якими ви не користуєтесь.
+- Одна ціль на сесію за раз.

+title: 会话目标
+description: 将一条提示词变成目标，代理会自动持续朝它推进。
+---
+
+# 会话目标
+
+目标把一条提示词变成终点线。你不用在每次回复后催促代理"继续"，只需设置一次目标 — OpenChamber 会自动让会话朝目标推进，并在每一轮之后用独立的审核模型检查进度。即使你不在电脑前，它也会继续运行。
+
+## 启动目标
+
+1. 按下输入框中的靶心按钮。它亮起 — 目标模式已就绪。
+2. 输入提示词并发送。这条消息就成为目标内容。
+
+在现有会话和新会话草稿中都一样：启用靶心，写下第一条消息，发送 — 新会话一开始就带着已激活的目标。
+
+### 启动目标的更多方式
+
+- **从代理的回复**：在 "Start new session from this answer" 对话框中勾选**作为目标运行** — 回复将作为任务移交，新会话会把它执行到完成（与 **Create worktree** 结合可获得隔离的运行环境）。
+- **从计划**：在新会话或 worktree 中实施已保存的计划时，在对话框中勾选**作为目标运行**。目标会携带计划内容，因此审核会以实际计划为准判断进度。
+- **按计划**：在[计划任务](/scheduled-tasks/)上勾选**作为目标运行**，让周期性运行把提示词推进到完成。
+
+## 写一个自包含的目标
+
+进度审核模型只能看到你的目标和代理的最新回复 — 看不到聊天历史。因此，请把目标消息写得让一个不了解对话上下文的人也能明白完成状态是什么样子。
+
+- 好的写法："为导出模块添加测试，并让整个测试套件通过。"
+- 不太好的写法："修一下" 或 "按那个思路继续。"
+
+对于小的上下文跟进，不需要目标 — 发一条普通消息就行。
+
+## 工作原理
+
+当代理停下且会话安静片刻后，OpenChamber 会：
+
+1. 让一个小而便宜的模型将最新一轮与目标对照审核：继续、完成，还是卡住了？
+2. 如果判定是"继续"，就发送续跑提示词，代理重新开始工作。
+3. 如果目标已被可验证地达成，目标即完成，你会收到通知。
+4. 如果代理真的卡住了（需要你的介入），目标会以"已阻塞"停止 — 但只有在审核连续三次这样判定之后，所以一次小挫折绝不会终结目标。
+
+还有硬性安全限制：可选的令牌预算、自动续跑次数上限，以及轮次出错时停止。如果会话上下文在工作途中被压缩，目标会照常继续 — 撞上上下文窗口本身就证明工作还没完成。
+
+### 停止与恢复
+
+- **停止按钮**会中断正在运行的轮次并暂停目标 — 你明确的"停"永远优先于循环。
+- 条带上的**暂停**从另一个方向做同样的事：暂停目标并停止正在运行的轮次。
+- 暂停期间正常聊天即可 — 循环不会打扰。
+- **继续**重新启动循环：在空闲会话上，续跑提示词会立即发出；如果代理恰好在工作，循环会在它下一次停顿时静静接上。
+
+## 查看与管理
+
+- 输入框上方的条带显示目标的最新进度备注、状态和令牌用量，并内置暂停/继续按钮。当代理已停止而目标仍激活时，条带会显示旋转的**评估中…** — 那是静默窗口和审核正在运行。
+- 靶心按钮在目标运行时保持点亮（蓝色），完成时变绿，阻塞或预算耗尽时变红。按下它可打开目标对话框：编辑目标或预算，或移除目标。已完成的目标为只读 — 先移除，再启动新目标。
+- 在会话侧边栏中，会话日期旁会出现一个小靶心，颜色对应目标状态。
+
+## 通知
+
+目标激活期间，每轮的"代理就绪"通知会被抑制 — 它们只会重复循环自己的续跑。目标尘埃落定时（完成、阻塞或达到预算），你会收到一条最终通知，出现在桌面并作为移动推送。它遵循同一个"完成时通知"设置；权限请求、提问和错误通知全程照常工作。
+
+## 令牌预算
+
+在 **设置 → 聊天 → 目标** 中可以为新目标设置默认令牌预算。目标达到预算时会以"已达预算"停止而不再消耗 — 你可以提高预算并从目标对话框中恢复。
+
+## 注意事项
+
+- 目标循环运行在 OpenChamber 服务器中，而不是浏览器标签页里。关掉标签页、锁上手机 — 代理继续工作，目标尘埃落定时你会收到通知。服务器（桌面应用或 `openchamber` 进程）必须保持运行。
+- 目标使用会话自身的提供商和模型，包括审核调用 — 数据不会流向你未在使用的提供商。
+- 每个会话同时只能有一个目标。
+
+## 相关

+- [计划任务](/scheduled-tasks/) — 按计划运行提示词；在那里启用"作为目标运行"，让计划运行将提示词推进到完成
+- [通知](/notifications/) — 如何得知目标已完成

+# Session Goal
+
+Server-side control loop that keeps a session working toward a user-defined
+objective stored under `metadata.openchamber.goal`, with the small model as
+an independent progress auditor. Built on OpenChamber's backend-driven
+architecture (session-assist is the structural template): the loop lives in
+the web server and survives UI disconnects.
+
+## Goal payload (`metadata.openchamber.goal`)
+
+```
+{
+  id,                      // opaque per-logical-goal id; stale-write guard
+  objective,               // user text, <= 2000 chars
+  status,                  // active | paused | blocked | budgetLimited | complete
+  tokenBudget,             // optional positive int
+  tokensUsed,              // tokensCommitted + current segment (snapshot - baseline)
+  tokensBaseline,          // segment start snapshot (pre-goal turn; 0 after compaction)
+  tokensCommitted,         // closed segments' total (one segment per compaction)
+  turnsUsed,               // auto-continuations sent (capped at MAX_AUTO_TURNS)
+  blockedStreak,           // consecutive blocked audit verdicts
+  auditFailStreak,         // consecutive failed/unavailable audit calls
+  note,                    // latest audit progress note, <= 280 chars
+  statusReason,            // why settled; 'resumed' is a kickoff signal from UI
+  lastAccountedMessageID,  // incremental accounting cursor
+  createdAt, updatedAt
+}
+```
+
+The UI writes goals (create/edit/pause/resume/clear) by patching this
+metadata; the runtime never creates a goal on its own. Goal creation happens
+at send time via the arm store (`useSessionGoalArmStore`): the composer
+target button arms "the next prompt is the objective", and the run-as-goal
+flows (fork-from-answer dialog, plan implement dialog) arm the same way —
+the plan flow additionally supplies an objective OVERRIDE carrying the plan
+content, since "Implement this plan: X" alone gives the audit nothing to
+judge against. The armed send also attaches a synthetic system-reminder
+part telling the agent goal mode is active and that each turn should end
+with a factual done/verified/remaining statement for the independent audit.
+Freshness/stale-write protection is by `id`: every runtime write re-reads the
+session and drops the write when the stored goal id no longer matches.
+
+## Flow
+
+1. `createSessionGoalRuntime` subscribes to the global SSE hub (same pattern
+   as session-assist — it needs the envelope's `directory`).
+2. `session.status: idle` arms a 15s per-session timer; `busy`/`retry` clears
+   it. A `session.updated` carrying a fresh active goal (`turnsUsed === 0` or
+   `statusReason === 'resumed'`) arms a kickoff timer — 3s for fresh goals,
+   ~250ms for an explicit Resume so the nudge feels immediate — since setting
+   a goal on an idle session emits no status transition.
+3. On fire (`tick`), gated by the `sessionGoalEnabled` setting:
+   - fetch session (skip sub-agent sessions), require an `active` goal;
+   - quiescence check via the message tail (trailing user message or
+     unfinished assistant reply → bail; the next idle transition re-arms);
+   - token accounting as a SNAPSHOT of the latest completed assistant turn:
+     `input + cache.read + output`. Earlier turns' inputs and outputs fold
+     into the next turn's cache, so the latest snapshot already carries the
+     whole run's paid tokens — no summing across messages. Goal-relative via
+     `tokensBaseline` (the same snapshot of the newest pre-goal turn,
+     captured on the first tick). Compaction (an assistant message with
+     `summary: true`) breaks the snapshot chain, so accounting is segmented:
+     the summary message closes the segment into `tokensCommitted` (the
+     summary turn read the whole context, so its snapshot prices the
+     compaction itself) and the next segment starts with a zero baseline.
+     `tokensUsed = tokensCommitted + current segment`, kept monotonic so
+     unflagged context shrinks never move the budget backwards;
+   - a user abort pauses the goal instead of blocking it: the event path in
+     `processPayload` pauses immediately on the MessageAbortedError message
+     (before any tick could send a continuation over the user's explicit
+     stop), with a tick-side safety net. Messages sent while paused leave
+     the goal alone; Resume re-arms the loop, and resuming over an aborted
+     tail skips the audit and goes straight to a continuation nudge;
+   - terminal checks, cheapest first: assistant turn error → `blocked`;
+     `tokensUsed >= tokenBudget` → `budgetLimited`;
+     `turnsUsed >= MAX_AUTO_TURNS` (20) → `blocked`;
+   - if the latest message is a compaction summary, skip the audit and
+     continue unconditionally — running into the context window mid-work is
+     by definition "in progress, not finished" (the summary is a retelling,
+     not evidence, and must not be judged);
+   - otherwise, small-model audit of the objective + the last assistant turn
+     only — no conversation history and no continuation prompts
+     (`restrictToPreferredProvider`, session's own provider/model preferred):
+     JSON `{verdict: continue|complete|blocked, note}`. The audit is the SOLE
+     termination authority besides the hard stops above — the working agent
+     has no channel to settle its own goal. `complete` settles; `blocked`
+     increments `blockedStreak` and settles only after 3 consecutive blocked
+     verdicts, so a one-off snag cannot end the goal. Audit failure/absence
+     tolerates ONE consecutive unaudited continuation (`auditFailStreak`); a
+     second consecutive failure settles the goal as `blocked` ("progress
+     audit unavailable") — resumable, and settling resets the streak so
+     Resume gets fresh tolerance. A dead small model can never drive the
+     loop blind to the turn cap;
+   - continue: persist accounting + `turnsUsed` first (a crash after the
+     write just waits for the next idle tick; the reverse could double-send),
+     re-check the tail, then `POST /session/:id/prompt_async` with the
+     continuation prompt using the last assistant message's
+     provider/model/agent — the goal spends the session's own subscription.
+4. Settling (`complete`/`blocked`/`budgetLimited`) fires the injected
+   `emitGoalNotification` so the user hears about it even with the UI closed:
+   desktop + UI broadcast + the standard push fanout (web-push with full
+   text; APNs with a generic per-type title and the session name as body).
+   It obeys the notify-on-completion setting. Conversely, while a goal is
+   ACTIVE the notifications runtime suppresses per-turn "ready"
+   notifications on every channel — they would only echo the loop's own
+   continuations; error/question/permission notifications are untouched.
+   Pausing a goal from the UI also aborts the running turn (and vice versa —
+   an abort pauses the goal), so "stop" means stop on both axes.
+
+## Continuation prompt
+
+Built inline in `runtime.js`: the objective as untrusted user data in an
+XML-escaped `<objective>` block, budget numbers, keep-the-full-objective and
+work-from-evidence rules, a completion-audit instruction, and the requirement
+to end every turn with a factual done/verified/remaining report — the audit
+sees only that final turn, so the report is its evidence.
+
+## UI consumers (packages/ui)
+
+- `lib/sessionGoalMetadata.ts` — payload parsing/types.
+- `lib/sessionGoalActions.ts` — create/edit/pause/resume/clear via
+  `patchSessionMetadata`; `lib/sessionGoalPresentation.ts` — status
+  colors/labels shared across surfaces.
+- `stores/useSessionGoalArmStore.ts` — the "next prompt starts a goal" flag,
+  consumed by `sendMessage` in `sync/session-ui-store.ts` (works for drafts).
+- `hooks/useSessionGoal.ts` — live goal state.
+- `components/chat/SessionGoalButton.tsx` — composer target button
+  (arm / status color / cancel confirm); `SessionGoalRow.tsx` — goal strip
+  above the composer; `SessionGoalDialog.tsx` — manage dialog
+  (edit/pause/resume/complete/clear).
+- Sidebar glyph next to the date in `SessionNodeItem`.
+
+## Scheduled goals
+
+Scheduled tasks can run as goals: `execution.goalEnabled` (+ optional
+`execution.goalTokenBudget`) on a task makes the scheduled-tasks runtime
+stamp `metadata.openchamber.goal` onto the fresh session (objective = the
+expanded task prompt) and attach the goal-mode intro part to the prompt.
+The loop here picks it up from session events like any other goal.
+
+## Limitations
+
+- Web-server feature: VS Code (extension-only) renders goal state via
+  `session.updated` but does not run the loop.
+- A goal on a session with no assistant reply yet starts after the first
+  user exchange completes (no provider/model to continue with before that).
+- `tokensUsed` only counts completed assistant messages seen within the
+  40-message fetch window per tick; extremely long busy stretches between
+  idles undercount (acceptable: budget is a guardrail, not billing).

+// Session goal: a persisted, self-continuing objective attached to a session

Subject: [PATCH 12/43] feat: file-backed goal objectives + compaction
 accounting fixes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Compaction fixes (observed in a real long run):
- the summary message's zeroed tokens froze the goal counter at its
  pre-compaction value; segments now close with the previously displayed
  total as a continuity floor
- audits and continuations after a summary tail now take execution params
  (provider/model/agent/variant) from the newest non-summary assistant
  turn instead of inheriting agent 'compaction' and the summarize model

File-backed objectives:
- the objective text lives in <data-dir>/goals/<sessionId>.md, keyed by
  session id (one goal per session, a new goal overwrites the file);
  metadata carries only an objectiveFile flag so session.updated fanout
  stays light, and never a path — ids are pattern-validated before any
  filesystem access
- limit raised to 5000 chars, no snapshot field: the UI fetches content
  via PUT/GET/DELETE /api/goals/objective/:sessionId (behind the blanket
  /api auth gate), writes the file before stamping metadata, and falls
  back to an inline objective when the write fails
- the loop reads the file fresh on every tick, so objectives are
  live-editable mid-goal; a missing file falls back to the inline text
- scheduled goal tasks write the objective file server-side; VS Code
  degrades to the audit note (route unavailable there by design)

 Freshness/stale-write protection is by `id`: every runtime write re-reads the
 session and drops the write when the stored goal id no longer matches.
 
+## File-backed objectives
+
+The objective TEXT lives in `<data-dir>/goals/<sessionId>.md` (data dir =
+`OPENCHAMBER_DATA_DIR` or `~/.config/openchamber`), keyed by the SESSION ID:
+sessions are globally unique and carry one goal at a time, so the mapping is
+deterministic and a new goal simply overwrites the file. Metadata carries
+only `objectiveFile: true` — never a path — so user-writable metadata cannot
+become a file-read vector (`objectives.js` also validates the id shape
+before touching the filesystem). Rationale: metadata rides every
+`session.updated`, so multi-KB objectives must not live there.
+
+- `objectives.js` — write/read/delete, 5000-char clamp.
+- `routes.js` — `PUT/GET/DELETE /api/goals/objective/:sessionId`
+  (OpenChamber-owned, registered before the generic proxy; JSON parsing via
+  the `/api/goals` family in core-routes). The UI writes the file BEFORE
+  patching the goal metadata and falls back to an inline objective when the
+  write fails; `clearSessionGoal` deletes the file best-effort.
+- The tick resolves the effective objective fresh on every cycle (the file
+  is live-editable mid-goal) and falls back to the inline `objective` when
+  the file is unreadable — a goal never dies because a file went away.
+- UI display fetches content via the GET route
+  (`useGoalObjectiveContent`); in VS Code the route is unavailable, so the
+  strip degrades to the audit note (display-only fallback by design).
+- Scheduled goal tasks write the file server-side directly via
+  `objectives.js`.

Subject: [PATCH 13/43] fix(mobile): eliminate >10s sidebar open delay by
 always mounting SessionSidebar (#1695) (#1738)

* fix(mobile): always mount SessionSidebar to eliminate >10s drawer open delay (#1695)

On mobile (Android PWA), SessionSidebar was conditionally mounted via
{mobileLeftDrawerVisible && ...}, causing the component to unmount on
drawer close and remount on every open. Each remount fired a full
data-loading cascade: paginated sessions fetch (PAGE_SIZE=500 with
retry), worktree discovery, repo status, PR status, 10+ useMemo
recomputations, and localStorage reads, manifesting as a >10s delay
before the drawer became interactive.

Desktop already avoided this by keeping SessionSidebar always mounted
inside <Sidebar> with a CSS visibility toggle.

Fix: remove the mobileLeftDrawerVisible conditional wrapper so
SessionSidebar stays mounted on mobile too, matching desktop behavior.
Visibility remains controlled by the leftDrawerX transform (off-screen
when closed). Added pointer-events-none when hidden as a defensive guard.

Added a regression test that fails if the conditional mount pattern is
reintroduced around the mobile SessionSidebar.

* fix(mobile): hide closed drawer to avoid rotation offset leak

+
+A Goal is a persistent completion contract, not an implementation plan and not a larger one-shot prompt. Help the user define what "done" means clearly enough that another agent can work toward it, verify it against evidence, continue through uncertain intermediate steps, and stop honestly when completion is blocked.
+
+Run this as a guided dialogue, not a one-shot answer.
+
+1. Start from the user's intent. If the visible message includes an initial idea, use it immediately. Otherwise ask what they want to accomplish. Do not ask them to formulate the Goal themselves.
+
+2. Investigate before asking when context is available. For repository work, inspect relevant code, tests, scripts, documentation, and conventions when that would answer questions or expose constraints. Do not ask for information that can be determined reliably from the workspace.
+
+3. Decide whether a Goal is appropriate. Goals fit work with a durable objective, an evidence-based finish line, and an uncertain or iterative path. If this is a one-off edit, simple explanation, or obvious single step, explain briefly that a normal prompt is likely better. Continue crafting a Goal if the user still wants one.
+
+4. Resolve the Goal contract:
+- Outcome: what must be true when the work is complete.
+- Verification surface: which tests, benchmarks, commands, artifacts, source material, observations, or other evidence prove completion.
+- Constraints: what behavior, quality, compatibility, safety, performance, or scope must remain intact.
+- Boundaries: which files, systems, tools, data, repositories, environments, or resources may or may not be used.
+- Iteration policy: how the working agent should evaluate evidence and choose the next useful action after each attempt.
+- Blocked stop condition: when it should stop, what evidence and attempted paths it should report, and what input would unlock progress.
+
+5. Ask only necessary questions, in batches of at most 3. Prefer concrete, decision-oriented questions. Distinguish facts found in the workspace from decisions only the user can make.
+
+6. Do not over-prescribe the path. Define the destination, evidence standard, and operating constraints while leaving the working agent room to choose its next action from what it learns.
+
+7. Do not invent precision. Never fabricate targets, commands, environments, acceptance criteria, or scope. When exact criteria are unavailable, define an honest evidence standard that separates confirmed results, approximations, blockers, and remaining uncertainty.
+
+8. Do not implement the task. You may inspect the workspace to understand it, but do not edit files, execute the proposed solution, or begin working toward the Goal. This session's deliverable is the Goal itself.
+
+9. Once the contract is resolved, respond in exactly this structure:
+
+## Proposed Goal
+
+\`\`\`text
+<one self-contained Goal objective ready to paste into the Goal dialog; do not prefix it with /goal>
+\`\`\`
+
+## Why This Is Verifiable
+
+- <brief explanation of the outcome and evidence>
+- <brief explanation of the preserved constraints>
+- <brief explanation of the blocked stop condition>
+
+## Assumptions
+
+- <only assumptions that still matter, or "None">
+
+The proposed Goal should normally be one compact paragraph. Keep enough operational detail to make completion auditable, but remove conversational history, rationale, repetition, and implementation details that are not part of the completion contract.
+
+Do not activate, execute, or claim completion of the proposed Goal. End by inviting the user to revise it or use it in the Goal dialog.
+
 Respond in the same language the user uses.`,

Subject: [PATCH 15/43] fix(notifications): handle subagents and session errors
 (#2156)

Use authoritative session.idle and session.error events for notifications
while retaining legacy message.updated handling for compatibility.

Classify sessions through targeted, directory-aware session lookups instead
of fetching the full session list. Cache confirmed root and parent session
relationships without treating failed lookups as root sessions.

Honor subagent completion settings and templates across the server-driven
web, desktop, and mobile paths, and bring the VS Code webview notification
policy to feature parity.

Use freshly synchronized VS Code settings, retry failed settings syncs,
extract session error messages, and deduplicate authoritative and legacy
completion and error events.

 Provider modules must export `providerId`, `providerName`, `aliases`, `isConfigured(auth?)`, and `fetchQuota()`.
 `fetchQuota()` should return a quota result with `usage.windows` keyed by window name (for example `5h`, `7d`, `daily`) and optional provider-specific `usage.models` data.
 
+OpenCode Go credentials are explicitly supplied by the user through Settings. OpenChamber never scans browser cookie stores. The server validates the credential before an atomic `0600` write and never returns the cookie through its API.

Subject: [PATCH 17/43] feat: persist permission auto-accept on server (#2158)

Move per-session permission auto-accept policy ownership from the UI to the
OpenChamber server so enabled sessions continue running when clients disconnect
or the server restarts.

- persist explicit per-session policies in OpenChamber settings
- inherit the nearest explicit policy across subagent session hierarchies
- allow child sessions to opt out of an inherited parent policy
- immediately accept matching global and directory-scoped pending requests
- process future requests without requiring a connected UI client
- reconcile pending permissions after startup and event-stream reconnects
- deduplicate concurrent requests and retry transient reply failures
- synchronize policy updates across connected clients
- migrate existing browser-persisted policies to server storage
- suppress auto-accepted permission cards before they enter UI state
- show deduplicated permission toasts for inactive sessions
- preserve foreground-only permission handling in VS Code
- integrate directory-aware notification routing from main
- add coverage for persistence, inheritance, retries, reconciliation, pending
  requests, client hydration, and inactive-session toasts

+# Permission Auto-Accept
+
+## Purpose
+
+This module owns the authoritative permission auto-accept policy for web, desktop, and mobile runtimes. Policy is persisted in OpenChamber settings so permission handling survives UI disconnects and server restarts.
+
+## Policy
+
+`permissionAutoAccept.sessions` contains explicit per-session boolean policies.
+
+Policy inheritance uses the nearest explicit session value. A child `false` therefore overrides a parent `true`; descendants without an explicit value inherit from their nearest configured ancestor.
+
+## Runtime
+
+`createPermissionAutoAcceptRuntime` loads and serializes policy writes, subscribes to the global OpenCode event hub, caches session lineage, retries transient replies, and reconciles pending permissions after startup, reconnect, and policy enablement. Enabling Auto-Accept for a session immediately accepts matching pending requests and keeps handling future requests without requiring a connected UI.
+
+Unknown lineage and failed policy loads fail closed. A failed pending-permission fetch is distinct from an empty successful response and never clears policy state.
+
+## Routes
+
+- `GET /api/permission-auto-accept`
+- `PUT /api/permission-auto-accept/sessions/:sessionId`
+
+These are normal authenticated OpenChamber runtime routes. They must not be added to browser URL-token allowlists.
+
+## UI ownership
+
+`packages/ui/src/stores/permissionStore.ts` is a projection of server policy and does not persist an independent policy. The server is the sole responder and the UI renders pending requests until the authoritative `permission.replied` event arrives.
+
+VS Code retains its foreground-only implementation because it does not run the web server runtime.
+
+## Tests
+
+`runtime.test.js` covers restart persistence, nearest explicit subagent inheritance, missing-lineage lookup, retry/deduplication, and reconnect reconciliation.

Subject: [PATCH 20/43] refactor(quota): secure managed provider credentials
 (#2160)

- add shared owner-only credential storage for OpenCode Go, Ollama Cloud, and Cursor
- validate credentials before atomic writes using 0700 directories and 0600 files
- replace provider-specific credential routes with an allowlisted lifecycle API
- stop automatically reading Ollama's legacy cookie file
- stop reading or modifying Cursor's database during regular quota requests
- add explicit one-time Cursor credential import without mutating Cursor storage
- persist refreshed Cursor credentials only in OpenChamber-managed storage
- add Ollama Cloud and Cursor credential controls to provider settings
- preserve OpenCode Go tracking through the shared credential flow
- add VS Code credential management and Cursor quota parity
- reject authentication redirects, enforce request timeouts, and fail on unparseable usage pages
- mask stored secrets in API responses and extend quota security coverage
- update quota provider documentation

 Provider modules must export `providerId`, `providerName`, `aliases`, `isConfigured(auth?)`, and `fetchQuota()`.
 `fetchQuota()` should return a quota result with `usage.windows` keyed by window name (for example `5h`, `7d`, `daily`) and optional provider-specific `usage.models` data.

+OpenCode Go, Ollama Cloud, and Cursor credentials are explicitly managed through Settings. The server validates credentials before atomic `0600` writes and never returns secrets through its API. OpenChamber never scans browser cookie stores or automatically reads Cursor storage; Cursor import is an explicit one-time user action and never modifies Cursor's database.

Subject: [PATCH 21/43] feat: distill oversized plan goals into audit criteria
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Plan-goal objectives are capped at 5000 chars for the auditor while the
working agent reads the full plan from its file. Plans over the limit are
now distilled by the small model into completion criteria (end goals +
per-phase verification, no implementation steps), prefixed with a header
pointing back at the plan file so every continuation re-anchors on the
live source of truth. If distillation fails (transient small-model
hiccup), a head+tail excerpt keeps the plan's intent (top) and acceptance
criteria (bottom) with a trim marker between — sacrificing the
implementation middle the agent reads from the file anyway — and a toast
tells the user the objective is degraded.

From d11704df63861177c7b74dcce5559d3015621c99 Mon Sep 17 00:00:00 2001
From: Bohdan Triapitsyn <artmore@protonmail.com>
Date: Sun, 12 Jul 2026 16:34:16 +0300
Subject: [PATCH 22/43] feat: distill any oversized goal objective, not just
 plans
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The distillation moved from PlanView into setSessionGoal — the shared
choke point for every goal source (composer, fork dialog, plans) — and
into the scheduled-tasks goal creation server-side. Any objective over
5000 chars is distilled into completion criteria by the small model; on a
transient failure a head+tail excerpt keeps the intent (top) and the
acceptance criteria (bottom) with a trim marker, plus a toast. The
working agent always received the full prompt in chat — only the auditor
is bound by the limit.

- the goal dialog renders as the shared MobileOverlayPanel bottom sheet
  on mobile instead of a centered dialog
- tapping the target button to ARM keeps the soft keyboard open (the next
  message is the objective; same guard as the attachment/mic buttons),
  while opening the manage sheet lets the keyboard close as usual
- capacitor: bottom-sheet overlays cap their height by the keyboard inset
  AND the top safe area — with the keyboard raised while typing inside a
  sheet, 100dvh does not shrink (native resize is off) and the panel could
  slide under the notch/status bar; applies to every MobileOverlayPanel

Subject: [PATCH 24/43] feat: connection candidates refresh + relay identity
 hardening

Candidates refresh (server + mobile + desktop clients):
- GET /api/client-auth/connection/candidates returns the server's current
  LAN URLs, relay candidate, and serverId for already-paired devices
- /health and /api/version expose serverId so clients can verify a learned
  address belongs to the expected server before sending their bearer token
- mobile: refresh saved candidates over the live transport after every
  connect/wake, hot-switch relay->LAN when a fresh address is reachable;
  serverId gate on direct probes; token no longer sent to /health
- desktop: refresh stored host apiUrl after a relay connect and hot-switch
  back to direct; electron probe verifies serverId before authenticated fetch

Fixes found while debugging a dead pairing:
- settings: strict reader that throws on corrupt/unreadable file instead of
  returning {}; relay signing/encryption key generation is now gated on it,
  so a swallowed read failure can no longer mint a new server identity and
  orphan every paired device (loud log when a keypair IS generated)
- SessionAuthGate: bounded auto-retry for transient session-check failures
  (initial request racing the relay tunnel's first WS attempt, startup 5xx)

+## Candidate refresh (staying off the relay when direct works)
+
+Pairing-payload transport candidates are a snapshot: when DHCP hands the host
+machine a new LAN address, a device's saved direct candidate goes stale and the
+device silently degrades to relay-only. To recover, an already-paired client can
+call `GET /api/client-auth/connection/candidates` (UI session or client bearer;
+registered with the auth/access routes) over any live transport — including
+through the tunnel — to learn the server's **current** LAN URLs plus the relay
+candidate, and update its saved candidate set (mobile: `mobileConnections.ts`;
+desktop: `desktopRelayRestore.ts`).
+
+Identity gating: the response carries the stable `serverId` (base64url SHA-256 of
+the public signing JWK — the same identity the relay routes by, exposed by the
+relay service's `getServerId()` and echoed unauthenticated on `/health` and
+`/api/version`). Clients ignore a refresh whose `serverId` does not match their
+pinned relay identity, and verify `/health`'s `serverId` on a learned address
+**before** sending their bearer token to it — a re-assigned LAN address may now
+belong to a different machine.
+
 ## Two implementations, kept in sync
 
 The E2EE and framing logic exists twice: TypeScript in `packages/ui/src/lib/relay/` (shared by the client and the normative reference) and a JavaScript mirror in this module (the host, which is plain JS ESM). They **must stay byte-compatible** — a client encrypted by one must decrypt on the other. A cross-compatibility test (`cross-compat.test.js`) imports the TS modules directly and exercises a full TS-client ↔ JS-host exchange. Any change to the wire format, frame codec, handshake, or batching must update both sides and keep that test green.

Subject: [PATCH 26/43] fix: single relay host per machine via cooperative
 claim lock
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

All local instances share the data dir and therefore the relay identity
(serverId), so concurrent relay hosts evicted each other at the relay worker
(4001: Control replaced) and paired devices landed on whichever local process
won last — often a stale dev server, surfacing as 'Unable to reach server'
and devices stuck on relay with 503s on newer endpoints.

- relay/host-lock.js: per-machine claim file (relay-host.lock, {pid}); stale
  claims from dead pids are ignored; unwritable data dir falls back to
  pre-lock behavior
- relay/service.js: start only when the claim is free or ours, otherwise
  'standby' with the holder pid in lastError; 30s watcher takes over when the
  claimant dies and stands down when another process claims; pairing-link
  creation and explicit /relay/enable force-claim (user intent wins)
- mobileConnections.ts: log candidate-refresh skip reasons and the refresh
  result instead of failing silently

 - `identity.js` — the host's stable identity: the long-lived signing keypair (shared with the push relay, defines the routing id) plus a long-lived encryption keypair (the E2EE trust anchor). Reused across restarts; never rotated implicitly.
 - `signing-key.js` — storage/derivation of the signing keypair and the routing id, shared with the notifications runtime.
 - `host-client.js` — the long-lived connection manager: one outbound control connection to the relay, a per-client data connection for each connected device, reconnect/backoff, and the E2EE responder handshake per connection.
+- `host-lock.js` — the per-machine host claim. Every local instance sharing the data dir shares the relay identity (same serverId), so concurrent relay hosts evict each other at the relay worker (`4001: Control replaced`) and paired devices land on whichever local process won last. The claim file (`<data-dir>/relay-host.lock`, `{ pid }`) makes this deterministic: `service.js` only starts the host when no LIVE process holds the claim (stale claims from dead pids are ignored), goes to `standby` otherwise, and a 30s watcher both takes over when the claimant dies and stands down when another process claims. Explicit user intent — creating a pairing link or hitting `/relay/enable` — force-claims; the previous holder's watcher sees the takeover and backs off instead of fighting. The claim is cooperative (the relay worker still enforces the single host slot); it only decides which process keeps retrying.
 - `tunnel-host.js` — the per-connection dispatcher: decrypts tunnel frames and forwards HTTP/SSE/WS to the local server over loopback, then streams responses back. Enforces a path allowlist and never injects credentials.
 - `e2ee.js`, `tunnel-codec.js` — host-side (JS) mirrors of the shared crypto and framing (see "Two implementations" below).

Subject: [PATCH 29/43] perf: fast relay connect on mobile and desktop +
 connect splash + edit-safe instances
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Relay connect used to serialize a dead LAN probe (up to 8s per stale address
on mobile, 2-4s on desktop) in front of the relay attempt, then paid a second
WebSocket connect + E2EE handshake because the probe tunnel was thrown away.

- mobile probeConnectionCandidates: race the relay probe against the direct
  chain with a 1.5s direct headstart; a live LAN still wins, a dead one no
  longer delays startup
- relay probes adopt their tunnel as the runtime tunnel (adoptRelayTunnel)
  instead of dialing a fresh one — applies to auto-connect, pairing redeem,
  password login, and the desktop host switcher's relay fallback
- relay probe drops the /health round-trip: the E2EE handshake already proves
  the server identity, /auth/session alone proves liveness and auth
- desktop restoreDesktopRelayRuntime: same headstart race; a late direct
  success hot-switches back (stable runtimeKey); startup probe now passes
  expectedServerId so a re-leased LAN address never sees the token
- launch splash shows 'Connecting to device: <label>' with animated dots
  under the (still centered) logo, translated in all locales
- editing a saved instance no longer rebuilds it from the URL field alone:
  the id is passed through, relay/https candidates are preserved, and a
  token-key change migrates the Keychain token instead of orphaning it

Subject: [PATCH 31/43] fix(ui,server): normalize Windows drive letter casing
 for consistent path resolution (#2154)

* fix(ui,server): normalize Windows drive letter casing for consistent path resolution

Provider settings were failing to persist for specific projects on Windows
because path normalization was inconsistent across the codebase. Some
normalizePath functions uppercased the Windows drive letter (c:\ -> C:\)
and others did not, causing:
  - directoryScoped cache misses (different keys for the same directory)
  - broken model selection in the affected project
  - lost conversation history (sessions could not match their project)
  - false cache hits in resolveConfigDirectory on undefined inputs

This change extracts a single shared normalizePath utility and uses it
from the 5 client sites that were missing the drive letter normalization.
The server-side normalizePathForPersistence is updated to uppercase the
drive letter both before and after safeRealpathSync, so the persisted
path is consistent even when realpath returns a symlink/junction with
a lowercase drive letter on some Windows environments.

Fixes #2109

* test(ui,server): add coverage for Windows path normalization

Address review feedback on #2154:
- Add Windows-platform test for normalizePathForPersistence covering
  drive letter uppercase on input and after realpath resolution
- Add dedicated test suite for the shared normalizePath utility
- Defensive fix: normalizePath now returns null for paths that consist
  only of slashes (\\, ///), matching the documented contract

Refs #2154

* fix(server): scope drive casing normalization to Windows

 ## [Unreleased]
 
+## [1.16.0] - 2026-07-13
+
+- **Session goals:** arm the new target button in the composer and your next prompt becomes a [goal](https://docs.openchamber.dev/session-goals/) — the session keeps working toward it on its own, with an independent small-model audit checking each finished turn, until the objective is verifiably complete, blocked, or over its optional token budget. The loop runs on the server, so it continues with the app closed and survives restarts. A goal strip above the composer shows progress with pause/resume; goals can also start from the plan-implement dialog, from scheduled tasks ("Run as goal"), or with the new "Craft a Goal" starter and `/craft-goal` command. While a goal runs, per-turn "ready" notifications are replaced by a single notification when it settles.
+- **Usage:** OpenCode Go usage tracking is here, and Codex quota windows now show the correct reset times.
+- **Remote access:** connecting over the relay got much faster — the app no longer waits for a stale local address to time out before trying the relay (previously up to ~20 seconds on a phone away from home). When your computer gets a new local IP, paired devices now learn the new address over the relay and quietly move back to the local network on their own — no re-pairing. The phone's launch screen shows which device it is connecting to.
+- Remote access: running several OpenChamber instances on the same machine no longer makes paired devices land on a random one of them — only one process per machine serves the relay now. This was behind intermittent "Unable to reach server" errors on paired phones.
+- Permissions: per-session auto-accept now lives on the server — sessions keep auto-accepting tool calls while the app is closed and after a server restart, subagent sessions inherit the setting, and it can be enabled on a draft before the first message (thanks to @bashrusakh for the draft fix).
+- Chat: subagent sessions can now be prompted directly — open a subagent from the context panel and send it follow-up messages (off by default, available in settings).
+- Chat: queued messages now send when the session is already idle instead of waiting forever in some cases, pending agent questions stay answerable after a server restart, and session renames no longer flicker back to the old title (thanks to @bashrusakh).
+- Files: the file viewer has a markdown preview toggle (thanks to @greghaynes).
+- Sidebar: projects can be sorted by different modes with a direction toggle, pinned sessions survive refreshes, and the file tree stays expanded while it refreshes (thanks to @bashrusakh).
+- Command palette: projects are included in the fuzzy search alongside sessions and files (thanks to @bashrusakh).
+- Settings: chat visual settings are grouped into labeled sections, and a new editor font size setting for the code editor (thanks to @bashrusakh).
+- GitHub: PR and issue context now resolves against the source repository in fork workflows (thanks to @bashrusakh).
+- Agents: saving agent settings from the UI no longer drops custom YAML frontmatter fields (thanks to @bashrusakh).
+- Notifications: session errors and subagent completions now notify reliably across desktop, web, and mobile.
+- Editor: "Open in" now recognizes VS Code Insiders.
+- Windows: paths no longer mismatch on drive letter casing, which could split one project into duplicates (thanks to @bashrusakh).
+- Mobile: the sessions sidebar opens instantly instead of taking many seconds on some devices (thanks to @tomzx).
+- Mobile: renaming a saved instance no longer breaks its connection — the stored access token was getting lost on edit.
+- Mobile: on Android 15 the app no longer draws under the status bar.
+- Security: requests that spoof local host headers to look like same-machine traffic are rejected.
+
 ## [1.15.0] - 2026-07-10
 
 - **Remote access:** a new [private relay](https://docs.openchamber.dev/private-relay/) lets you reach your instance from anywhere — no open ports and no third-party tunnel, over an end-to-end-encrypted tunnel. It turns on by itself when you pair a device over it and turns off once no paired device uses it (thanks to @yulia-ivashko).

+- Chat: sessions with an active [goal](https://docs.openchamber.dev/session-goals/) (started from the web or desktop app) show the goal strip with its live status above the composer.

 ## [1.15.0] - 2026-07-10
 
 - Chat/Tools: every tool call now expands to show its input, result, and errors, including MCP, plugin, and custom tools; Read and Skill stay compact links to their files. JSON results now offer navigable summary, tree, and raw views.

* feat(electron): add Linux AppImage releases

* ci: cache Linux OpenCode CLI artifacts

* fix(ci): await Linux release inventory check

* fix(electron): add frameless window controls on Linux desktop

Linux AppImages were created without native WM decorations and without
in-app controls, leaving users unable to close the window with a mouse.

Treat Linux like Windows: frameless BrowserWindow plus the existing
WindowsWindowControls header buttons and app-menu entry. macOS keeps
hidden title bar with traffic lights unchanged.

Shared usesFramelessElectronChrome() helper drives main window, mini
chat, header insets, and titlebar controls.

Co-authored-by: Serhii Dziupin <makeittech@users.noreply.github.com>

* feat(desktop): add configurable window controls position by OS

Add desktopWindowControlsPosition setting (auto/left/right) with OS-aware
defaults: Linux left, Windows right. Wire frameless chrome controls in
Header, TitlebarLeftControls, and MiniChatLayout, plus a Sessions settings
control for Windows and Linux desktop shells.

Co-authored-by: Serhii Dziupin <makeittech@users.noreply.github.com>

* fix(desktop): address Linux AppImage release review findings

Propagate updater capability errors to the UI, treat missing
latest-linux.yml feeds as no-update, stop installed-apps IPC spam on
Linux, document FUSE/AppImage limits, add CHANGELOG entry, migrate
remaining btriapitsyn URLs, and run Electron Linux unit tests on PRs.

 ## [Unreleased]
 
+- **Desktop/Linux:** official AppImage releases for x86_64 and arm64, with in-app window controls (position follows OS defaults or Settings → Sessions), writable-AppImage auto-update, and clearer updater errors when the AppImage is missing or read-only. Linux does not yet include system tray or launch-at-login.
+
 ## [1.16.0] - 2026-07-13
 
 - **Session goals:** arm the new target button in the composer and your next prompt becomes a [goal](https://docs.openchamber.dev/session-goals/) — the session keeps working toward it on its own, with an independent small-model audit checking each finished turn, until the objective is verifiably complete, blocked, or over its optional token budget. The loop runs on the server, so it continues with the app closed and survives restarts. A goal strip above the composer shows progress with pause/resume; goals can also start from the plan-implement dialog, from scheduled tasks ("Run as goal"), or with the new "Craft a Goal" starter and `/craft-goal` command. While a goal runs, per-turn "ready" notifications are replaced by a single notification when it settles.

+Desktop supports macOS, Windows, and Linux. The build output is written to `packages/electron/dist`.
 
 macOS builds create `dmg` and `zip` files. You need Xcode/build tools for notarized packaging and icon asset work.
 
 Windows builds create an NSIS installer. If signing env vars are not set, the build script makes an unsigned installer.
 
+Linux builds produce an AppImage for the native x64 or arm64 host.

-Linux is supported for web/CLI development. A Linux desktop app is still planned, so Electron packaging is mainly macOS and Windows right now.
+Linux x64 and arm64 AppImages are packaged natively on the matching host architecture. Use Bun for dependency installation and packaging orchestration:
+
+```bash
+OPENCHAMBER_TARGET_ARCH=x64 bun run electron:build
+# On an arm64 host:
+OPENCHAMBER_TARGET_ARCH=arm64 bun run electron:build

+The final AppImage verifier checks desktop identity and the architecture of Electron, the bundled OpenCode CLI, and packaged native modules.

 This package owns the native shell: windows, menus, deep links, native notifications, auto-updates, host switching, SSH connections, tunnel helpers, and packaged desktop builds. The web UI and OpenChamber server logic still live in `packages/web` and shared React UI lives in `packages/ui`.

+macOS builds produce `dmg` and `zip` artifacts. Windows builds produce an NSIS installer. Linux builds produce an AppImage for the native x64 or arm64 host.
 
 ## Platform Notes
 
@@ -74,7 +74,19 @@ macOS packaging needs Xcode/build tools for notarized builds and icon asset comp
 
 Windows packaging needs NSIS support through `electron-builder`. If no Windows signing env is set, `package.mjs` disables code signing and builds an unsigned installer.
 
-The package supports macOS and Windows desktop features. Some native discovery helpers are platform-specific. For example, app icon fetching and app filtering currently only work on macOS, while opening files in installed apps works on macOS and Windows.
+Linux AppImages must be built natively. Set `OPENCHAMBER_TARGET_ARCH=x64` or `OPENCHAMBER_TARGET_ARCH=arm64` when packaging; the build rejects a target that does not match the Linux host. The same target selects the bundled OpenCode CLI, native Electron rebuild, and Electron Builder architecture. Linux identity is stable across architectures: executable `openchamber`, desktop file `openchamber.desktop`, icon `openchamber`, and `StartupWMClass=openchamber`.
+
+After packaging, run `bun run --cwd packages/electron verify:linux-appimage`. The verifier extracts the final AppImage and checks its ELF architecture, desktop identity, Electron executable, pinned OpenCode CLI version and architecture, and all packaged native `.node` modules.
+
+Running a packaged Linux AppImage requires FUSE (`libfuse.so.2`, typically `libfuse2` / `libfuse2t64` on Debian/Ubuntu). Without FUSE, start with `APPIMAGE_EXTRACT_AND_RUN=1`. Keep the AppImage on a writable path so in-app updates can replace it.
+
+Linux updates are supported only when the packaged app is running from a writable AppImage. Update checks, downloads, and installation report an actionable error when `APPIMAGE` is missing, invalid, or read-only; a missing release feed (`latest-linux.yml` 404 before the first Linux publish) is treated as “no update available”. macOS and Windows updater behavior is unchanged. Release builds keep `latest-linux.yml` (x64) and `latest-linux-arm64.yml` separate and validate each manifest against its AppImage before upload. Linux AppImages download full updates (no `.blockmap` differential channel yet).
+
+### Updater End-to-End Fixture
+
+A loopback-only updater fixture is available for contributor QA of N-to-N+1 AppImage replacement and restart behavior. It is test infrastructure, not a user-configurable update source. See [`scripts/updater-e2e-fixture.md`](./scripts/updater-e2e-fixture.md) for the controlled test procedure. Unit tests cover feed selection, check failures, no-update results, and fixture generation; actual AppImage replacement and restart remains a manual native N-to-N+1 release boundary because it requires executing two packaged versions on each supported architecture.
+
+The package supports macOS, Windows, and Linux desktop features. Linux AppImage builds include in-app window controls and auto-update; system tray and launch-at-login remain macOS/Windows only. Some native discovery helpers are platform-specific. For example, app icon fetching and app filtering currently only work on macOS, while opening files in installed apps and installed-app discovery work on macOS and Windows (Linux returns an empty list without errors).

+# Linux Updater E2E Fixture
+
+This local-only harness verifies AppImage N-to-N+1 replacement without changing the
+production GitHub updater provider. It supports native x64 and arm64 hosts.
+
+1. Build both versions on the native target architecture. For N and N+1, set the
+   test-build marker only while bundling main, then complete normal packaging:
+
+   ```bash
+   OPENCHAMBER_TARGET_ARCH=x64 OPENCHAMBER_UPDATER_E2E_BUILD=1 bun run bundle:main
+   OPENCHAMBER_TARGET_ARCH=x64 node ./scripts/package.mjs --linux --x64 --publish=never
+   ```
+
+   Use `OPENCHAMBER_TARGET_ARCH=arm64` and `--arm64` on an arm64 host. Keep the N and
+   N+1 AppImages in separate output directories before rebuilding.
+
+2. Launch N against a loopback fixture containing N+1:
+
+   ```bash
+   bun run updater:e2e:fixture -- run \
+     --arch x64 \
+     --current /absolute/path/OpenChamber-N-linux-x86_64.AppImage \
+     --next /absolute/path/OpenChamber-N+1-linux-x86_64.AppImage \
+     --version N+1 \
+     --dir /tmp/openchamber-updater-e2e
+   ```
+
+3. In N, check for updates, download/install, and restart. Verify the restarted app
+   reports N+1 and that the file at `APPIMAGE` was replaced. Repeat with `--arch arm64`
+   and the arm64 AppImages on the arm64 host.
+
+The harness binds only `127.0.0.1`. Runtime override activation additionally requires
+`OPENCHAMBER_E2E=1`, the loopback URL set by the harness, and the build-time marker.
+Normal packages omit the build-time marker and always use `openchamber/openchamber`.
+The renderer, IPC bridge, command-line arguments, and persistent configuration do not
+have access to the feed URL.

Subject: [PATCH 40/43] feat(chat): desktop prompt navigator rail (#2054)

* feat(chat): add desktop prompt navigator rail

Add a ChatGPT-style right-center prompt marker rail for web/desktop chat
with hover/keyboard preview panel, load-more for partial history (panel only),
Chat setting, and mod+alt+p shortcut. Disabled in VS Code across rail,
shortcut, settings, help, and search surfaces.

Co-authored-by: Serhii Dziupin <makeittech@users.noreply.github.com>

* fix(ui): read promptNavigatorEnabled from getState in shortcut handler

Match the file convention used by other shortcut handlers so the toggle
does not rely on a hook-level selector closure.

Co-authored-by: Serhii Dziupin <makeittech@users.noreply.github.com>

* fix(ui): drop use-no-memo and default prompt navigator off

Remove the project-unprecedented React Compiler opt-out, and ship the
prompt navigator as opt-in to match other recent chat UI toggles.

Subject: [PATCH 42/43] fix(chat): rework prompt navigator rail into sliding
 tape with hover preview (#2185)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(chat): rework prompt navigator rail into sliding tape with hover preview

- Pin the active indicator to the target during programmatic scrolls so the
  scroll spy's intermediate reports don't drag it backwards mid-animation
- Replace the visibility-ratio active-turn picker with a stable reading-line
  rule (last turn whose top is above the line), dropping IntersectionObserver
- Replace the list panel with a Codex-style gutter: the whole strip is one
  hover/click target mapped to the nearest tick, with a per-prompt preview
  card that follows the cursor
- Cap the rail at a fixed window of ticks; hovering the edges carousels
  through the rest, with gradient masks hinting at more content
- Render ticks as a tape that glides to keep the active prompt centered,
  remounting on history prepend to avoid spurious slide animations
- Keep load-earlier as a compact button aligned over the tick column

* fix(chat): shrink navigator gutter when message column sits under it

On narrow windows the centered message column extends under the rail's
full-width invisible hover zone, which swallowed clicks on the right edge
of user bubbles — including the expand/collapse control. Measure the
column against the gutter and switch to a narrow hit zone when they
overlap.

* fix(sync): stop runaway history auto-load on sessions with empty assistant messages

An assistant message fetched with zero parts (e.g. a run aborted before any
output) was stored as absence — indistinguishable from parts that were never
fetched. getSessionMaterializationStatus therefore reported the session as
never renderable, so the ensure-renderable effects (ChatContainer,
ModelControls) retried syncSession forever; each retry refetched the whole
grown window and fired another background prepend, progressively loading the
entire history of large sessions on open.

Commit an explicit empty [] snapshot for assistant messages so fetched-empty
counts as renderable, while non-assistant messages keep the absent
representation and its no-op commit behavior.

Reproduced and verified headless against a real 857-message session: before,
20 message fetches escalating to limit=857; after, one initial page and a
single progressive-mount prepend.

Subject: [PATCH 43/43] fix(quota): Ollama Cloud credential validation and UI
 decoupling (#2187)

- ollama-cloud.js: redirect: 'manual' -> 'follow', remove 3xx check,
  remove empty-windows check, add /signin URL detection for invalid cookies
- VS Code parity: add redirect: 'follow', 401/403, /signin detection
- ProvidersPage.tsx: decouple ollama from ollama-cloud credential section
- QuotaCredentials.tsx: add help text + dedicated cookie label
- ollama-cloud.test.js: updated tests + /signin regression test
- en.settings.ts: new ollamaCloud.help and ollamaCloud.cookie i18n keys
