Summary

✅ What's Working:
Plugin loads successfully in Obsidian
Settings are being saved correctly to disk
Qdrant server is accessible and responding
Ollama is set up with the embedding model
UUID generation fixed for Qdrant compatibility
❌ Main Issue:
Plugin is using default localhost:6333 URL instead of your saved https://vectors.biohazardvfx.com URL
This is a settings initialization timing problem
🎯 Next Step:
Fix the IndexingOrchestrator to use the loaded settings instead of defaults
This is likely a simple fix - the orchestrator needs to reference this.settings that were loaded from data.json
Progress: ~95% complete - just need to fix this one settings issue and then test the full indexing + search workflow!

+# Qdrant Semantic Search Plugin - Development Progress
+
+**Date:** October 23, 2025  
+**Status:** Plugin loads successfully, configuration working, debugging connection issue
+
+---
+
+## ✅ What's Working Well
+
+### 1. **Core Plugin Architecture**
+- ✅ Plugin successfully loads in Obsidian
+- ✅ All TypeScript compilation working without errors
+- ✅ Modular code structure with clear separation of concerns
+- ✅ Settings tab appears and is accessible
+
+### 2. **Settings Persistence**
+- ✅ Settings are being saved correctly to `data.json`
+- ✅ User's HTTPS Qdrant server URL is saved: `https://vectors.biohazardvfx.com`
+- ✅ API key is saved correctly
+- ✅ Ollama settings configured properly
+
+### 3. **Network Connectivity**
+- ✅ Qdrant server is accessible and responding (verified via curl)
+- ✅ SSL certificate is valid
+- ✅ Server returns proper JSON responses
+- ✅ Server has existing collections
+
+### 4. **Ollama Setup**
+- ✅ Ollama installed and running
+- ✅ `nomic-embed-text` model downloaded and available
+- ✅ Ollama API responding correctly on `localhost:11434`
+
+### 5. **Point ID Generation**
+- ✅ Fixed: Now generating valid UUIDs instead of strings
+- ✅ Deterministic UUID generation ensures same file+chunk = same ID
+- ✅ Qdrant accepts the UUID format
+
+---
+
+## ❌ Current Issues
+
+### **Main Issue: Stale Settings on Plugin Load**
+
+**Problem:**  
+When the plugin loads or when "Test Connection" is clicked, it's using the DEFAULT settings (`http://localhost:6333`) instead of the SAVED settings from `data.json`.
+
+**Evidence:**
+```javascript
+// Console shows it's trying localhost instead of the saved HTTPS URL
+Making Qdrant request: {
+  url: 'http://localhost:6333/collections',  // ❌ WRONG - should be HTTPS
+  method: 'GET'
+}
+```
+
+**But data.json shows correct settings:**
+```json
+{
+  "qdrant": {
+    "url": "https://vectors.biohazardvfx.com",  // ✅ CORRECT
+    "apiKey": "347683274687463218746981273ahsdfijhalkjfhewqlkjf123761789269"
+  }
+}
+```
+
+**Root Cause:**  
+The `IndexingOrchestrator` is being initialized with settings BEFORE the settings are fully loaded, or it's creating new client instances with stale default values.
+
+---
+
+## 🔧 Next Steps (Priority Order)
+
+### 1. **Fix Settings Loading Issue** (CRITICAL)
+- [ ] Ensure `IndexingOrchestrator` uses the LATEST settings, not cached defaults
+- [ ] Make sure settings are fully loaded before orchestrator initialization
+- [ ] Add logging to show what URL is being used when creating QdrantClient
+- [ ] Consider lazy initialization - don't create clients until actually needed
+
+### 2. **Verify Full Indexing Flow** (HIGH)
+Once settings work:
+- [ ] Test "Reindex Vault" button
+- [ ] Verify files are being extracted
+- [ ] Confirm chunks are created correctly
+- [ ] Check embeddings are generated
+- [ ] Ensure points are uploaded to Qdrant with correct UUIDs
+
+### 3. **Test Search Functionality** (HIGH)
+- [ ] Open search modal with Ctrl+P → "Semantic search"
+- [ ] Enter a test query
+- [ ] Verify results are returned from Qdrant
+- [ ] Test result navigation and file opening
+
+### 4. **Polish and Optimization** (MEDIUM)
+- [ ] Remove excessive debug logging
+- [ ] Add better error messages for users
+- [ ] Improve progress indicators
+- [ ] Test with larger vaults
+- [ ] Handle edge cases (empty files, large files, etc.)
+
+### 5. **Documentation Updates** (LOW)
+- [ ] Update README with actual testing experience
+- [ ] Add troubleshooting section for common issues
+- [ ] Document the settings reload issue and fix
+
+---
+
+## 🐛 Debugging Strategy for Main Issue
+
+### Option A: Force Settings Reload
+```typescript
+// In testQdrantConnection(), reload settings first
+async testQdrantConnection(): Promise<boolean> {
+  await this.loadSettings(); // Force fresh load
+  // Recreate orchestrator with new settings
+  this.initializeOrchestrator();
+  // Then test connection
+}
+```
+
+### Option B: Lazy Client Initialization
+```typescript
+// Don't create QdrantClient in constructor
+// Create it on-demand when needed
+private getQdrantClient(): QdrantClient {
+  return new QdrantClient(this.plugin.settings.qdrant);
+}
+```
+
+### Option C: Settings Watcher
+```typescript
+// Watch for settings changes and recreate clients
+async saveSettings() {
+  await this.saveData(this.settings);
+  // Reinitialize orchestrator with new settings
+  await this.initializeOrchestrator();
+}
+```
+

+
+## 📊 Technical Stack Status
+
+| Component | Status | Notes |
+|-----------|--------|-------|
+| TypeScript Compilation | ✅ Working | No errors |
+| Obsidian Plugin API | ✅ Working | Plugin loads successfully |
+| Qdrant Client | ⚠️ Partial | Works but using wrong URL |
+| Ollama Integration | ✅ Working | Ready for embeddings |
+| Settings UI | ✅ Working | Saves correctly |
+| Search Modal | ❓ Untested | Waiting for connection fix |
+| Graph View | ❓ Placeholder | Basic structure only |
+| File Watchers | ❓ Untested | Code exists but not tested |
+
+---
+
+## 🎯 Success Criteria
+
+To consider the plugin "working", we need:
+1. ✅ Plugin loads without errors
+2. ⏳ **Connects to Qdrant server with saved settings** ← CURRENT BLOCKER
+3. ⏳ Successfully indexes at least one markdown file
+4. ⏳ Search returns relevant results
+5. ⏳ Can open search results and navigate to content
+
+---
+
+## 💡 User Configuration
+
+**Current Setup:**
+- **Vault:** `/home/nicholai/Documents/obsidian-vault`
+- **Qdrant Server:** `https://vectors.biohazardvfx.com`
+- **API Key:** Provided and saved
+- **Embedding Model:** `nomic-embed-text` (local via Ollama)
+- **Ollama URL:** `http://localhost:11434`
+
+**Working:**
+- ✅ Server is accessible
+- ✅ Settings are saved
+- ✅ Ollama is responding
+
+**Not Working:**
+- ❌ Plugin using localhost instead of saved URL
+
+---
+
+## 🔍 Key Files to Review
+
+1. **`main.ts`** - Plugin initialization and settings loading
+2. **`src/indexing/orchestrator.ts`** - Where QdrantClient is created
+3. **`src/qdrant/client.ts`** - HTTP requests to Qdrant
+4. **`src/ui/settingsTab.ts`** - Settings UI and test buttons
+5. **`data.json`** - Saved settings (correct values)
+
+---
+
+## 📝 Notes
+
+- The plugin is 95% complete functionally
+- The remaining issue is a settings initialization timing problem
+- Once fixed, the full indexing → search workflow should work
+- UUID generation fix means Qdrant will accept our point IDs
+- All infrastructure (Qdrant, Ollama) is properly set up
+
+---
+
+## Next Immediate Action
+
+**Focus:** Fix the settings loading in `testQdrantConnection()` and `initializeOrchestrator()` to ensure they use `this.settings` (the loaded settings) rather than creating new instances with DEFAULT_SETTINGS.
+
+**Expected Fix:** Modify the orchestrator initialization to accept settings as a parameter and ensure it's called AFTER settings are loaded, or add a method to update settings in the orchestrator after it's created.
