Architecture: Idea Vault (Gen 7)

Architecture: Idea Vault (Gen 7)

## Overview
The Idea Vault is a local-first mobile extension for the Trajectory ecosystem. It focuses on rapid capture and reliable sync.

## Core Components
1. Local Store (Vault):
- Uses SQLite (via Expo SQLite or similar) for offline-first persistence.
- Schema: `ideas (id, content, audio_uri, transcription, created_at, synced_status, metadata)`

2. Sync Engine:
- Background sync service.
- Conflict resolution: Last-write-wins (for Gen 7).

3. Quick Capture Widget:
- Minimalist UI for one-tap text entry.
- Voice trigger button.

4. Voice-to-Idea:
- Audio recording module.
- Whisper or Device-native STT integration.

## Tech Stack (Proposed for Gen 7 Prototype)
- Framework: React Native (Expo)
- Storage: `expo-sqlite`
- Voice: `expo-av` + `expo-speech-recognition` (or similar)
- Sync: REST/WebSockets

## Generation 7 Goals
- [ ] Scaffold React Native project structure.
- [ ] Define SQLite Schema.
- [ ] Implement local "Add Idea" logic.
- [ ] Implement "Voice Record" stub.
- [ ] Basic Sync status UI.
