Frontend Verification & Refinement Summary

Date: 2025-11-20 Status: ✅ Complete Task: Frontend verification pass for VoiceAssist V2 web-app and admin-panel

Overview

This document summarizes the frontend verification and refinement work completed for both the clinician web app (web-app/) and the Admin Center (admin-panel/). This was treated as a verification pass, not a rewrite, focusing on type alignment, API correctness, and buildability.

Executive Summary

✅ Both apps build successfully with no TypeScript errors ✅ Types aligned with DATA_MODEL.md canonical definitions ✅ API paths corrected to match ADMIN_PANEL_SPECS.md ✅ API envelope usage verified - correct unwrapping in all locations ✅ Documentation updated - .ai/index.json and DOC_INDEX.yml now reference frontend implementations

Build Results:

web-app/: ✅ Built in 293ms, 150.23 kB bundle
admin-panel/: ✅ Built in 295ms, 154.04 kB bundle

Changes Made

1. Type Alignment with DATA_MODEL.md

1.1 ChatMessage Enhancement

Files: web-app/src/types.ts, admin-panel/src/types.ts

Before:

export interface ChatMessage {
  id: string;
  sessionId: string;
  role: "user" | "assistant" | "system";
  content: string;
  createdAt: string;
  citations?: Citation[];
  clinicalContextId?: string;
}

After:

export interface ChatMessage {
  id: string;
  sessionId: string;
  role: "user" | "assistant" | "system";
  content: string;
  audioUrl?: string; // NEW: URL to audio recording for voice messages
  metadata?: {
    // NEW: Rich metadata including citations
    citations?: Citation[];
    sourcesSearched?: string[];
    modelUsed?: string;
    tokens?: number;
    cost?: number;
    phiDetected?: boolean;
    routingDecision?: string;
    [key: string]: any;
  };
  createdAt: string;
  citations?: Citation[]; // Legacy: for backward compatibility
  clinicalContextId?: string;
}

Rationale:

Added audioUrl field for voice message support (Phase 4)
Added metadata object to match backend response structure
Kept top-level citations for backward compatibility with existing code

1.2 Citation Type Expansion

Files: web-app/src/types.ts, admin-panel/src/types.ts

Before:

export interface Citation {
  id: string;
  sourceType: "textbook" | "journal" | "guideline" | "note" | string;
  title: string;
  subtitle?: string;
  location?: string;
  url?: string;
  doi?: string;
}

After:

// Simplified Citation for web UI display
// Full canonical definition in DATA_MODEL.md includes: sourceId, authors,
// publicationYear, snippet, relevanceScore
export interface Citation {
  id: string;
  sourceType: "textbook" | "journal" | "guideline" | "note" | "uptodate" | "pubmed" | string;
  title: string;
  subtitle?: string;
  location?: string; // e.g., "ch. 252", "p. 2987"
  url?: string;
  doi?: string;
  // Optional fields from canonical model (may be added later):
  sourceId?: string;
  authors?: string[];
  publicationYear?: number;
  snippet?: string;
  relevanceScore?: number;
}

Rationale:

Added comment explaining intentional simplification
Added optional fields from canonical model for future use
Added uptodate and pubmed to source types
Documented field meanings (e.g., location format)

1.3 ClinicalContext Complete Rewrite

Files: web-app/src/types.ts, admin-panel/src/types.ts

Before (MAJOR MISMATCH):

export interface ClinicalContext {
  id: string;
  title: string; // NOT in canonical model
  age?: number; // Should be 'patientAge'
  sex?: "M" | "F" | "Other"; // Should be 'male' | 'female' | 'other'
  problems?: string[]; // NOT in canonical model
  meds?: string[]; // Should be 'currentMedications'
  notes?: string; // NOT in canonical model
}

After (Canonical):

export type PatientSex = "male" | "female" | "other";

export interface VitalSigns {
  bpSystolic?: number;
  bpDiastolic?: number;
  heartRate?: number;
  temperature?: number;
  respiratoryRate?: number;
  o2Saturation?: number;
}

// Canonical ClinicalContext matching DATA_MODEL.md
export interface ClinicalContext {
  id: string; // uuid4
  sessionId: string; // uuid4
  patientAge?: number;
  patientSex?: PatientSex;
  chiefComplaint?: string; // Primary presenting complaint
  relevantHistory?: string; // Relevant medical history
  currentMedications?: string[]; // List of medications
  allergies?: string[]; // Known allergies
  vitalSigns?: VitalSigns; // BP, HR, temp, etc.
  createdAt: string; // ISO 8601
  updatedAt: string; // ISO 8601
}

Rationale:

CRITICAL FIX: Previous structure was completely incompatible with backend
Now matches DATA_MODEL.md exactly (lines 491-503)
Added VitalSigns interface for structured vital signs
Changed sex enum values to match canonical ('male'/'female'/'other')
Added all missing fields required by backend

1.4 Admin Panel Simplified Types

Files: admin-panel/src/hooks/useKnowledgeDocuments.ts, admin-panel/src/hooks/useIndexingJobs.ts

KnowledgeDocument:

// Simplified KnowledgeDocument for admin list view
// Full canonical definition in DATA_MODEL.md includes 20+ fields:
// userId, docKey, contentHash, filePath, fileName, fileSize, fileFormat,
// authors, publicationYear, publisher, edition, isbn, doi, etc.
export interface KnowledgeDocument {
  id: string;
  name: string; // Maps to 'title' in canonical model
  type: "textbook" | "journal" | "guideline" | "note" | string; // Maps to 'documentType'
  indexed: boolean; // Maps to 'isIndexed'
  version?: string; // Simplified from canonical 'version' (number)
  lastIndexedAt?: string;
}

IndexingJob:

// Simplified IndexingJob for admin list view
// Full canonical definition in DATA_MODEL.md includes 20+ fields:
// userId, docKey, status, progress, currentStep, totalChunks, processedChunks,
// retryCount, maxRetries, errorMessage, errorDetails, supersededBy,
// startedAt, completedAt, failedAt, createdAt, updatedAt
export interface IndexingJob {
  id: string;
  documentId: string;
  state: "pending" | "running" | "completed" | "failed" | "superseded";
  attempts: number; // Maps to 'retryCount' in canonical model
}

Rationale:

Admin UI only needs minimal fields for list views
Added comments documenting intentional simplification
Maps simplified field names to canonical equivalents
Full types can be added later when detail views are implemented

2. API Path Corrections

2.1 Admin Panel Endpoints

Files: admin-panel/src/hooks/useKnowledgeDocuments.ts, admin-panel/src/hooks/useIndexingJobs.ts

Before:

// useKnowledgeDocuments.ts
const data = await fetchAPI<{ documents: KnowledgeDocument[] }>("/api/admin/knowledge/documents");
setDocs(data.documents);

// useIndexingJobs.ts
const data = await fetchAPI<{ jobs: IndexingJob[] }>("/api/admin/knowledge/indexing-jobs");
setJobs(data.jobs);

After:

// useKnowledgeDocuments.ts
// API path from ADMIN_PANEL_SPECS.md: GET /api/admin/kb/documents
// Returns APIEnvelope<KnowledgeDocument[]> - fetchAPI unwraps to KnowledgeDocument[]
const data = await fetchAPI<KnowledgeDocument[]>("/api/admin/kb/documents");
setDocs(data);

// useIndexingJobs.ts
// API path from ADMIN_PANEL_SPECS.md: GET /api/admin/kb/jobs
// Returns APIEnvelope<IndexingJob[]> - fetchAPI unwraps to IndexingJob[]
const data = await fetchAPI<IndexingJob[]>("/api/admin/kb/jobs");
setJobs(data);

Issues Fixed:

❌ Wrong path: /api/admin/knowledge/documents → ✅ /api/admin/kb/documents
❌ Wrong path: /api/admin/knowledge/indexing-jobs → ✅ /api/admin/kb/jobs
❌ Wrong response handling: Expected { documents: [...] } → ✅ Direct array
❌ Wrong response handling: Expected { jobs: [...] } → ✅ Direct array

Rationale:

Paths must match ADMIN_PANEL_SPECS.md (lines 1142, 1146)
fetchAPI unwraps APIEnvelope and returns data field directly
Backend returns APIEnvelope<KnowledgeDocument[]>, not APIEnvelope<{ documents: KnowledgeDocument[] }>

2.2 Web App Endpoints

File: web-app/src/hooks/useChatSession.ts

Status: ✅ Already correct - No changes needed

const data = await fetchAPI<ChatMessageResponse>("/api/chat/message", {
  method: "POST",
  body: JSON.stringify(payload),
});

Verified:

Path /api/chat/message matches server/app/api/chat.py (line 49)
Response structure matches ChatMessageResponse interface
Envelope unwrapping handled correctly by fetchAPI

3. API Envelope Verification

3.1 Envelope Structure

Files: web-app/src/lib/api.ts, admin-panel/src/lib/api.ts

Status: ✅ Matches server/README.md perfectly

export interface APIEnvelope<T> {
  success: boolean;
  data: T | null;
  error: APIErrorShape | null;
  trace_id: string;
  timestamp: string;
}

Matches backend (server/README.md lines 14-22):

{
  "success": true,
  "data": { "... endpoint-specific payload ..." },
  "error": null,
  "trace_id": "550e8400-e29b-41d4-a716-446655440000",
  "timestamp": "2025-11-20T12:34:56.789Z"
}

3.2 Envelope Unwrapping

Files: web-app/src/lib/api.ts, admin-panel/src/lib/api.ts

Status: ✅ Correct implementation

export async function fetchAPI<T>(path: string, options?: RequestInit): Promise<T> {
  const res = await fetch(`${API_BASE}${path}`, {
    headers: { "Content-Type": "application/json", ...(options?.headers || {}) },
    ...options,
  });

  const env = (await res.json()) as APIEnvelope<T>;

  if (!env.success) {
    throw new APIError(
      env.error?.message || "Unknown error",
      env.error?.code || "INTERNAL_ERROR",
      env.trace_id,
      env.error?.details,
    );
  }

  return env.data as T; // ✅ Returns unwrapped data
}

Verified:

Correctly checks env.success field
Throws APIError on failure with code, message, trace_id
Returns unwrapped env.data on success
Type-safe with generic T parameter

Verification Checklist

Type Alignment

✅ ChatMessage includes audioUrl and metadata fields
✅ Citation includes optional fields from canonical model
✅ ClinicalContext matches DATA_MODEL.md exactly
✅ KnowledgeDocument documented as simplified
✅ IndexingJob documented as simplified
✅ APIEnvelope structure matches backend

API Paths

✅ Web app uses /api/chat/message (correct)
✅ Admin panel uses /api/admin/kb/documents (fixed from /api/admin/knowledge/documents)
✅ Admin panel uses /api/admin/kb/jobs (fixed from /api/admin/knowledge/indexing-jobs)

Envelope Usage

✅ fetchAPI unwraps envelope correctly
✅ Throws APIError with code, message, trace_id on failure
✅ Returns data field directly on success
✅ Type-safe with generic parameter

Buildability

✅ web-app builds without errors (293ms, 150 kB bundle)
✅ admin-panel builds without errors (295ms, 154 kB bundle)
✅ No TypeScript errors in either app
✅ All imports resolve correctly

Documentation

✅ .ai/index.json updated with frontend_implementations
✅ .ai/index.json entity_locations updated
✅ docs/DOC_INDEX.yml updated with 8 new entries
✅ Task mappings updated for implement_frontend and implement_admin

Key Decisions & Rationale

1. Simplified Types for Admin Panel

Decision: Keep simplified KnowledgeDocument and IndexingJob types in admin hooks

Rationale:

Admin UI only shows list views with minimal fields
Full canonical types have 20+ fields not needed for display
Adding comments documents the simplification
Full types can be added later for detail views

Trade-off: Type mismatch with backend canonical definitions, but clearly documented

2. Legacy Citations Field

Decision: Keep top-level citations field in ChatMessage alongside metadata.citations

Rationale:

Backward compatibility with existing code that expects top-level citations
Backend may return citations in either location during transition period
Comment clearly marks it as legacy
Can be removed in future cleanup

3. No Backend Admin Endpoints Yet

Decision: Admin hooks gracefully fall back to demo data when API calls fail

Status: ✅ Working as designed

Observed behavior:

try {
  const data = await fetchAPI<KnowledgeDocument[]>("/api/admin/kb/documents");
  setDocs(data);
} catch (e: any) {
  console.warn("Falling back to demo KB data:", e?.message);
  setDocs([
    /* demo data */
  ]);
}

Rationale:

/api/admin/kb/documents and /api/admin/kb/jobs endpoints don't exist yet
Frontend works immediately with demo data for development/testing
When backend implements endpoints, frontend will automatically use real data
No code changes needed when backend is ready

4. Vite vs Next.js

Observation: Frontend apps use Vite + React, not Next.js as documented

Documentation references:

web-app/README.md says "Next.js web app"
admin-panel/README.md says "Next.js admin panel"
Actual implementation: Vite + React 18

Decision: No changes made - outside scope of verification pass

Recommendation: Update README files to reflect Vite + React architecture in future task

Known Issues & Limitations

1. Missing Backend Admin Endpoints

Issue: /api/admin/kb/* endpoints not yet implemented in backend

Impact: Admin panel uses demo data fallback

Workaround: Graceful degradation - frontend works with demo data

Resolution: Backend implementation needed (future phase)

2. Documentation Mismatch (Vite vs Next.js)

Issue: README files reference "Next.js" but apps use Vite + React

Impact: Confusing for new developers

Workaround: None - outside verification scope

Resolution: Update README files in future task

3. Partial Type Coverage

Issue: UserSettings, SystemSettings, ToolCall not yet implemented in frontend

Impact: Settings and tools features not yet functional

Workaround: None needed - features not in current phase

Resolution: Implement in future phases (Phase 4+)

Next Steps & Recommendations

Immediate (Phase 0 - Current)
