🔧 Key Enhancements by Section

Section 1: Architecture & Infrastructure

What Was Enhanced:

• ARCHITECTURE_V2.md: Added Docker Compose-first strategy, separate Nextcloud stack details
• LOCAL_DEVELOPMENT.md: Comprehensive local setup with two separate stacks
• INFRASTRUCTURE_SETUP.md: Production deployment for both stacks
• COMPOSE_TO_K8S_MIGRATION.md: Created migration path to Kubernetes

Key Decisions Documented:

• Docker Compose First: Build and deploy with Compose, migrate to K8s only when scaling needs arise
• Separate Nextcloud Stack: Independent docker-compose.yml for PHI isolation and compliance
• Integrated but Decoupled: HTTP APIs (OIDC, WebDAV) for integration without tight coupling

Section 2: Application Specifications

What Was Enhanced:

WEB_APP_SPECS.md:

• Added complete Clinical UX Workflows section (Quick Consult, Case Workspace, DDx Assistant, Drug Reference)
• Added detailed Voice Interface specifications (modes, VAD, noise suppression)
• Added API Integration section with complete endpoint documentation
• Added Frontend Architecture (Next.js, React Query, Zustand)

ADMIN_PANEL_SPECS.md:

• Added Dashboard & Analytics section (metrics, cost tracking)
• Added Knowledge Base Management interface
• Added User Management & RBAC specifications
• Added Audit Logs interface

SEMANTIC_SEARCH_DESIGN.md (Created):

• Document Ingestion Pipeline (PDF/DOCX parsing, chunking strategies)
• Vector Search Architecture (Qdrant integration, hybrid search)
• RAG Pipeline (query rewriting, reranking, response generation)

Section 3: Settings Model (User vs System)

What Was Enhanced:

WEB_APP_SPECS.md - User Settings:

• Complete UserSettings TypeScript interface with 8 categories:
  • General (language, timezone, theme, date/time format)
  • Voice (input device, activation mode, TTS settings)
  • Citations (display style, format, priority sources)
  • Display (font size, spacing, animations)
  • Clinical Context (specialty, practice type)
  • Privacy (query logging, PHI detection, telemetry)
  • Notifications (email, in-app, digest frequency)
  • Shortcuts (keyboard shortcuts)
  • Advanced (experimental features, debug mode)
• Backend API implementations (Python/FastAPI)
• Frontend hooks and UI components (TypeScript/React)
• Storage: PostgreSQL with Redis caching

ADMIN_PANEL_SPECS.md - System Settings:

• Complete SystemSettings TypeScript interface with 9 categories:
  • General (system name, maintenance mode)
  • Data Retention (log retention policies, auto-cleanup)
  • Backup (schedule, retention, encryption)
  • AI Configuration (model selection, routing strategy, rate limits, cost limits)
  • Logging (level, destinations, PHI redaction)
  • Security (MFA enforcement, session timeout, IP restrictions)
  • Email (SMTP configuration)
  • Feature Flags (enable/disable features)
  • Resource Limits (per-user quotas)
• Backend API with validation and audit logging

Key Components

Frontend:

• Web App (Vite + React): Clinical interface with voice support
• Admin Panel (Vite + React): System management and KB control
• Docs Site (Next.js 14): Technical documentation

Backend:

• FastAPI Server: REST APIs, WebSocket, voice transcription
• RAG Engine: LangChain-based semantic search and response generation
• PHI Detection: Presidio integration for HIPAA compliance
• AI Router: Local Llama 3.1 8B for PHI, OpenAI GPT-4 for general queries

Data Layer:

• PostgreSQL: Users, sessions, audit logs, settings
• Qdrant: Vector embeddings for semantic search
• Redis: Session caching, rate limiting
• Nextcloud: PHI document storage (separate stack)

Integrations:

• Nextcloud (OIDC, WebDAV)
• PubMed API
• UpToDate API
• External guidelines (CDC, WHO)

🔑 Key Decisions

1. Docker Compose-First Development Strategy

Decision: Build with Docker Compose for Phases 0-14, offer optional Kubernetes migration

Rationale:

• Faster development and debugging
• Lower operational complexity
• Production-ready after Phase 10
• Easy migration path to K8s when scaling needs arise
• Suitable for small-to-medium medical practices (< 100 users)

2. Separate Nextcloud Stack

Decision: Run Nextcloud in a separate Docker Compose stack with independent database

Rationale:

• PHI Isolation: Separate audit logs, backups, encryption keys for compliance
• Independent Maintenance: Update Nextcloud without affecting VoiceAssist
• Clear Security Boundary: Easier to audit and secure
• Scalability: Can scale or replace Nextcloud independently

3. HIPAA Compliance from Day 1

Decision: Build HIPAA controls into architecture from the beginning

Rationale:

• Retrofitting compliance is expensive and risky
• PHI detection must be core to AI routing logic
• Audit logging easier to implement from start
• Encryption and access controls simpler to add early

4. Hybrid AI Model (Local + Cloud)

Decision: Use local Llama 3.1 8B for PHI-containing queries, cloud GPT-4 for general queries

Rationale:

• Compliance: PHI never leaves the local server
• Quality: Leverage GPT-4's superior performance when safe
• Cost Optimization: Route to cheaper local model when possible
• Redundancy: Fallback options if one model fails

5. Phase-Based Development (15 Phases: 0-14)

Decision: Break project into 15 sequential phases (Phase 0 through Phase 14) with clear deliverables

Rationale:

• Each phase independently completable
• Clear entry and exit criteria
• Easy progress tracking
• Suitable for AI-assisted development (Claude Code)
• Estimated 90-110 hours total (Docker Compose-first approach)
• Phases 0-10: Docker Compose development
• Phases 11-14: Kubernetes migration and production deployment

📊 Development Timeline
