+
+## Current Focus
+
+hypothesis: confirmada — transcript leakage escapa por proteção incompleta e falta de sanitização; a exportação de debug em dev agora foi adicionada para inspecionar chats completos com metadados
+test: aguardar validação humana no fluxo real com pnpm tauri dev
+expecting: o botão flutuante apareça em chats no ambiente dev, copie o transcript completo, e a resposta não exiba mais blocos repetidos System/User/Assistant
+next_action: usuário validar no app real e confirmar se o bug sumiu
+
+## Symptoms
+
+expected: existir um botão flutuante de debug em todo chat, visível apenas em dev (pnpm tauri dev), capaz de copiar o chat completo com detalhes de mensagens do usuário e do modelo sem poluir a resposta do modelo
+actual: a resposta do modelo passa a incluir System/User/Assistant repetidos e trechos de histórico anterior; o sistema de debug desejado ainda não está disponível
+errors: saída do modelo contendo System/User/Assistant repetidos e histórico anterior indevido
+reproduction: abrir qualquer chat e enviar uma mensagem; a resposta exibida passa a incluir System/User/Assistant repetidos e trechos de histórico anterior
+started: começou após mudanças recentes no frontend de chat

+## Eliminated
+
+## Evidence
+
+- timestamp: 2026-04-02T00:05:00Z
+  checked: informações complementares do usuário
+  found: o problema reproduz em qualquer chat aberto ao enviar uma mensagem e começou após mudanças recentes no frontend de chat
+  implication: a regressão provavelmente está no frontend, não em dados específicos de um chat
+
+- timestamp: 2026-04-02T00:05:00Z
+  checked: exemplo de resposta da API
+  found: a API retorna message.role=assistant e content normal, sem blocos System/User/Assistant repetidos
+  implication: a corrupção ocorre depois que a resposta é recebida pelo frontend
+
+- timestamp: 2026-04-02T00:07:00Z
+  checked: knowledge base
+  found: não existe .planning/debug/knowledge-base.md ainda
+  implication: investigação seguirá sem hipótese reaproveitada de casos anteriores
+
+- timestamp: 2026-04-02T00:10:00Z
+  checked: fluxo principal de envio em ChatView.tsx e parser em lib/chat.ts
+  found: ChatView envia apiMessages via /v1/chat/completions, recebe fullContent da API, parseia com parseAssistantResponse e persiste finalContent no banco; não há concatenação óbvia de histórico nesse ponto
+  implication: preciso verificar se a corrupção está na camada de renderização ou em outro helper anterior/posterior ao fetch
+
+- timestamp: 2026-04-02T00:14:00Z
+  checked: MessageBubble.tsx, lib/markdown.ts e useMemoryExtractor.ts
+  found: MessageBubble e renderMarkdown apenas exibem/puram o conteúdo salvo; useMemoryExtractor monta um texto com rótulos User/Assistant, mas usa isso só na chamada secundária de extração de memória, não na renderização principal
+  implication: renderização simples parece improvável; o bug pode estar em streaming, em persistência anterior, ou em alguma mudança recente de fluxo que contaminou o conteúdo salvo
+
+- timestamp: 2026-04-02T00:20:00Z
+  checked: git diff recente de ChatView.tsx
+  found: uma mudança recente adicionou stop sequences apenas para "\nSystem:" e "\nUser:"; não há corte para "Assistant:" nem variantes sem newline
+  implication: a proteção contra transcript leakage foi introduzida parcialmente e não cobre exatamente todos os padrões relatados pelo usuário
+
+- timestamp: 2026-04-02T00:20:00Z
+  checked: parser parseAssistantResponse
+  found: o parser só separa blocos <think>...</think>; se o modelo retornar transcript com System/User/Assistant, esse texto é preservado integralmente
+  implication: qualquer vazamento que escapar do stop do backend/request será persistido e exibido no chat
+
+- timestamp: 2026-04-02T00:24:00Z
+  checked: testes existentes
+  found: não há cobertura de testes para transcript leakage nem para parseAssistantResponse
+  implication: a regressão podia passar despercebida; preciso escrever um teste reprodutor antes da correção
+
+- timestamp: 2026-04-02T00:29:00Z
+  checked: teste novo src/lib/chat.test.ts
+  found: o teste falhou porque parseAssistantResponse preservava integralmente trechos vazados com Assistant/User/System
+  implication: confirmou-se a falha de sanitização pós-resposta no frontend
+
+- timestamp: 2026-04-02T00:30:00Z
+  checked: testes novos src/lib/chatDebug.test.ts e src/components/ChatView.debug.test.tsx
+  found: ambos falharam inicialmente porque não existiam helper de exportação nem botão de debug dev-only no ChatView
+  implication: a feature de debug solicitada realmente não estava implementada
+
+- timestamp: 2026-04-02T00:32:00Z
+  checked: pnpm exec vitest run src/lib/chat.test.ts src/lib/chatDebug.test.ts src/components/ChatView.debug.test.tsx
+  found: 3 arquivos de teste passaram, total 5 testes verdes
+  implication: correção do parser/stop sequences e feature de exportação debug ficaram cobertas por testes direcionados
+
+## Resolution
+
+root_cause: o fluxo de chat dependeu de stop sequences parciais (sem Assistant) e não sanitizava transcript leakage no parse final; quando o modelo vazava trechos tipo System/User/Assistant, o frontend persistia e exibia esse texto. Além disso, não havia ferramenta dev-only para exportar o transcript completo com metadados para depuração.
+fix: parseAssistantResponse agora corta transcript leakage com papéis System/User/Assistant; ChatView usa stop sequences centralizadas com Assistant incluído e salva apenas conteúdo sanitizado; foi adicionado botão flutuante dev-only para copiar o chat completo com metadados de mensagens

+- Agentic mode shows a dedicated thinking/plan card immediately after the user prompt.
+- Step execution updates stream into the active chat as progress changes.
+- Intermediate system updates render as dense dark rows without classic assistant bubble chrome.
+- Final response renders as a clean text block with code-copy support and artifact action area.
+- Normal chat mode remains unchanged for non-agentic replies.
+- New behavior is covered by focused tests for formatting/render gating.
+</acceptance_criteria>
+
+<implementation_plan>
+1. Create chat-native agentic UI blocks (`AgentThinkingCard`, `AgentStepList`, `AgentSystemMessage`, `AgentFinalResponse`) and refactor `ForgeAgentBubble` to compose them.
+2. Extend forgeagent types to support transcript-level system messages and artifact CTA metadata needed by the new UI.
+3. Integrate agentic rendering into `ChatView` with conditional transcript blocks and Manus-like assistant presentation.
+4. Add a Rust→Tauri event contract for plan and step progress; wire frontend listeners to update live agentic state.
+5. Add targeted tests and update `.planning/STATE.md` / summary files after verification.

+## Completed
+
+- Added chat-native agentic UI blocks:
+  - `AgentThinkingCard`
+  - `AgentStepList`
+  - `AgentSystemMessage`
+  - `AgentFinalResponse`
+- Refactored `ForgeAgentBubble` to compose the new Manus-style sections instead of the older heavy card layout.
+- Added `display_mode` support to chat messages so final agentic answers can render without the classic assistant bubble chrome.
+- Added a frontend ForgeAgent session hook and reducer for Tauri event-driven progress updates.
+- Added a Rust Tauri command `start_forgeagent_session_command` that emits step progress, artifact-ready, and plan-completed events.
+- Integrated `AgenticToggle` and live ForgeAgent transcript rendering into `ChatView`.

+
+## Notes
+
+- The new Tauri ForgeAgent flow is an event-driven scaffold that enables the Manus-like transcript experience in the current chat UI.
+- Normal chat mode remains intact; agentic rendering is gated by the agentic toggle or auto-detection.

+# Phase 6: Chat UI Redesign - Context
+
+**Gathered:** 2026-04-02
+**Status:** Ready for planning
+
+## Phase Boundary
+
+The existing milestone already moved ForgeLM toward Manus-inspired colors and input composition, but the key agentic transcript experience is still missing. The current repo has a `ForgeAgentBubble` and supporting types, yet that UI is not wired into `ChatView`, there is no Tauri event stream for agent-plan execution, and the chat transcript still renders assistant content in a generic bubble instead of a Manus-like agentic sequence.
+
+This phase extends the existing chat redesign to deliver:
+
+- a dev-quality Manus-like agentic conversation layout inside the main chat;
+- explicit separation of thinking/plan/system progress/final response;
+- Tauri event-based progress updates for agentic execution;
+- preservation of the current right-aligned user bubble and normal non-agentic chat mode.
+
+## Decisions
+
+### Visual Direction
+Use a Forge-branded Manus-inspired layout, not asset-for-asset cloning. Preserve hierarchy, density, spacing, and interaction style.
+
+### Technical Direction
+Reuse existing `types/forgeagent.ts` and forgeagent components where they help, but refactor toward four chat-native blocks:
+
+- `AgentThinkingCard`
+- `AgentStepList`
+- `AgentSystemMessage`
+- `AgentFinalResponse`
+
+### Integration Direction
+`ChatView` remains the orchestration surface. Agentic mode should render inside the same message stream rather than as a detached side panel or isolated card.
+
+## Existing Code Insights
+
+- `ChatView.tsx` owns message rendering, streaming state, and persistence.
+- `ForgeAgentBubble.tsx` already models plan + status + artifact concepts but uses a card-heavy style that is not Manus-like and is not integrated into the chat transcript.
+- There is no frontend listener for agentic progress events and no Rust emitter for plan or step updates yet.
+- `types/forgeagent.ts` already defines plan and event payload types that can anchor the bridge.
+
+## Specific Ideas
+
+1. Add a fourth plan (`06-04`) rather than rewriting the earlier phase docs.
+2. Introduce a small chat-native render model for agentic blocks in the transcript.
+3. Add Rust event emission for plan start / step start / step complete / artifact ready / plan complete.
+4. Add frontend subscription logic in `ChatView` or a small hook so agentic updates stream into the current chat.
+5. Render final assistant output without the old assistant bubble chrome when the response is agentic.
+
+## Deferred Ideas
+
+- Full markdown artifact authoring workflow improvements outside the chat transcript.
+- Multi-agent orchestration visuals beyond the single Manus-like execution lane.
