CHECKPOINT - EVA-OS

Data: 2026-02-19

O QUE E O PROJETO

Sistema operacional AI-native visando Redox OS (microkernel Rust). Dois eixos:

  1. NPU Driver: driver userspace Intel NPU (Meteor Lake 0x7D1D) para Redox OS
  2. EVA Daemon: assistente voz IA com wake word, streaming audio, Time Machine AI

Tech Stack: Rust 100%, Tokio async, cpal audio, Gemini API, AES-256-GCM, ONNX Runtime, SQLite

O QUE FUNCIONA

NPU Driver (drive/)

  • PCI discovery Intel Meteor Lake NPU
  • MMIO read/write volatile
  • DMA contiguous memory
  • Firmware loading com validacao magic number
  • Boot 6 fases com hexspeak protocol
  • Command queue ring buffer 256 slots
  • Redox npu: scheme
  • Mock mode (Windows/Linux dev)
  • 5 testes passando

EVA Daemon (eva-daemon/)

  • Audio capture/playback real-time (cpal 16kHz PCM16)
  • Wake word "Hey EVA" (Energy/MFCC/ONNX)
  • VAD (RMS + zero-crossing)
  • EVA-Mind WebSocket (wss://eva-ia.org:8090)
  • Gemini API WebSocket (BidiGenerateContent)
  • Sessions encriptadas AES-256-GCM
  • Command parser + executor sandboxed
  • Time Machine AI (screenshot+OCR+embeddings+busca+encriptacao)
  • Terminal UI ANSI
  • Emotion detection (8 tipos)

C FFI (driver-c-api/) + ONNX API + OpenVINO

  • C FFI: 9 funcoes exportadas com cbindgen
  • DLLs OpenVINO pre-built presentes

O QUE FALTA

  1. Offline STT (Vosk) - codado mas nao integrado no main loop
  2. Local TTS (piper-rs) - nao iniciado
  3. Gemini client - codado mas main.rs usa EvaMindClient em vez
  4. Command pipeline - parser/executor nao conectados (sem STT -> sem texto)
  5. TimeMachine delete_today() - stub (retorna 0)
  6. SemanticIndex - HashMap simples (README diz FAISS mas nao existe)
  7. OCR ONNX - retorna "[ONNX OCR Output]" hardcoded
  8. Embedding ONNX - retorna vec![0.0; 384]
  9. Wake word ONNX - sempre retorna true sem parsear output
  10. OpenVINO build - CMake incompleto, fases 2-5 nao iniciadas

BUGS

  1. status_indicator.rs teste - assert Idle mas initial e Initializing (FALHA)
  2. sysinfo 0.29 API deprecated - usa traits removidos em 0.30
  3. eva_mind.rs - send_audio falha se session_created demora
  4. WebSocket receive() - println! debug em toda mensagem (flood)
  5. Salt fixo Argon2 - criptografia enfraquecida
  6. CPF hardcoded - "64525430249" no EvaMindConfig
  7. update_memory() a cada ~100ms - System::new_all() caro chamado excessivamente
  8. tls.rs, logging.rs, stt.rs - importados mas nunca usados

DEAD CODE

  • main_phase1.rs (main antigo)
  • Cargo_phase1.toml
  • test_inference.rs (solto na raiz)
  • gemini.rs (importado mas nunca usado)
  • tls.rs, logging.rs, stt.rs (modulos mortos)
  • search.rs (struct vazia)

.md PARA DELETAR

  • ONNX/projeto.md (0 bytes vazio)
  • STATUS_COMPILACAO.md (possivelmente obsoleto)
  • MD/Googolplex-Books.md (pertence a outro projeto)
