VoiceAssist V2 - Final Documentation Pass Summary

Date: 2025-11-20 Purpose: Comprehensive summary of the final documentation enhancement pass Status: Complete

Note: This is a historical summary from the 2025-11-20 documentation pass. For current documentation architecture and status:

Current Status: IMPLEMENTATION_STATUS.md

Docs System Architecture: INTERNAL_DOCS_SYSTEM.md (includes AI-Docs/Qdrant integration)

AI Agent API: AGENT_API_REFERENCE.md (machine-readable endpoints)

The DOC_INDEX.yml approach mentioned below has been superseded by the new agent/index.json, agent/docs.json, and Qdrant-based AI-Docs semantic search pipeline.

Overview

This document summarizes the final comprehensive documentation pass for VoiceAssist V2, which focused on:

Frontend Integration Details - Complete chat and admin UI patterns with React hooks
Observability Patterns - Metrics, logging, and alerting specifications
Machine-Readable Indexing - AI agent navigation with DOC_INDEX.yml
Complete Consistency - Ensuring all documentation references are valid

3. Key Design Decisions Documented

A. API Envelope Pattern

Standard: All API endpoints return:

{
  "success": boolean,
  "data": T | null,
  "error": {
    "code": string,
    "message": string,
    "details": object
  } | null,
  "trace_id": string,
  "timestamp": string
}

12 Standard Error Codes:

AUTH_FAILED, AUTH_REQUIRED, FORBIDDEN
VALIDATION_ERROR, RATE_LIMITED
PHI_DETECTED, PHI_REDACTED
KB_TIMEOUT, TOOL_ERROR, LLM_ERROR
INTERNAL_ERROR, NOT_FOUND, CONFLICT

Benefits:

Consistent error handling across frontend
trace_id for debugging
Machine-readable error codes

B. Idempotency Pattern

For Documents:

doc_key: Stable identifier (e.g., "textbook-harrisons-21e-ch252")
content_hash: SHA-256 hash of content
version: Integer version number
superseded_by: Reference to newer version

For Jobs:

Check for existing job with same doc_key before creating
Mark old jobs as superseded when new version uploaded
Prevents duplicate indexing

Benefits:

Safe retries
Version tracking
Document lifecycle management

C. IndexingJob State Machine

5 States:

pending - Job created, not yet started
running - Worker processing document
completed - Successfully indexed
failed - Error occurred, can retry
superseded - Newer version created

Progress Tracking:

total_chunks: Total chunks to process (nullable initially)
processed_chunks: Chunks processed so far
retry_count: Number of retry attempts
max_retries: Maximum allowed retries (default: 3)

Transitions:

pending → running (worker picks up)
running → completed (success)
running → failed (error)
failed → pending (retry)
Any → superseded (new version uploaded)

D. Observability with /health, /ready, /metrics

Three Standard Endpoints:

/health - Liveness probe
- Is the service process running?
- Returns 200 OK with service name and version
- Used by Kubernetes liveness probe
/ready - Readiness probe
- Are dependencies (DB, Redis, Qdrant) healthy?
- Returns 200 if all healthy, 503 if degraded
- Used by Kubernetes readiness probe
/metrics - Prometheus metrics
- Exports metrics in Prometheus format
- Scraped every 15 seconds
- Powers Grafana dashboards

Benefits:

Automatic health monitoring
Dependency failure detection
Historical metrics for debugging

E. Chat Data Flow with WebSocket Streaming

Pattern:

User sends message via REST POST /api/chat/message
Backend returns message ID and session ID
WebSocket /ws/chat/{session_id} streams deltas
Frontend appends deltas incrementally
Citations sent separately as assembled
Stream completes with "done" message

Fallback:

If WebSocket fails, use non-streaming REST
Complete message returned in single response

Benefits:

Better UX with streaming
Graceful degradation
Early feedback to user

F. Rounds Mode and Note Draft UX

Design Philosophy:

Clinician-centric workflows
PHI protection by default (local LLM)
Temporary storage with auto-expiration
Audit logging for compliance
Manual PHI redaction required before export

Rounds Mode:

Pin context for multiple questions
4-hour auto-expire
All queries use local LLM
Badge showing "Rounds Mode Active"

Note Draft Export:

Structured A/P format
Editable before export
Export events logged
Warning: "Review carefully and remove all PHI"

4. Data Model Enhancements

All enhancements are documented in DATA_MODEL.md with three representations each (JSON Schema, Pydantic, TypeScript).

A. KnowledgeDocument

Added Fields:

doc_key (string, unique) - Stable idempotency key
content_hash (string) - SHA-256 hash for change detection
version (integer, default: 1) - Document version number
superseded_by (uuid4, optional) - Reference to newer version

Purpose:

Enable idempotent uploads
Track document versions
Handle document updates without duplication

B. IndexingJob

Added Fields:

state (enum) - Job state: pending, running, completed, failed, superseded
doc_key (string) - Document key reference
total_chunks (integer, optional) - Total chunks to process

retry_count (integer, default: 0) - Number of retries
max_retries (integer, default: 3) - Max retry attempts
superseded_by (string, optional) - ID of newer job
error_details (object, optional) - Additional error context

Deprecated Fields (marked for removal):

status → use state
progress → use processed_chunks / total_chunks
chunks_created → use processed_chunks

Purpose:

Complete state machine tracking
Better progress reporting
Retry management
Supersession handling

C. KBChunk

Added Fields:

superseded (boolean, default: false) - Whether chunk is from old version
embedding_model (string) - Model used for embedding

Purpose:

Mark old chunks when document updated

Fields:

id (uuid4)
clinician_id (uuid4)
clinical_context_id (uuid4) - Pinned context

status (enum) - active, expired, closed

Purpose:

Fields:

id (uuid4)
session_id (uuid4)
message_id (uuid4) - Source AI response
