Phase 0 Frontend Investigation Status
Date: September 17, 2025
Time: 08:37 AM PDT
Agent: Cursor Agent
Issue: #172 CORE-UI Layer 3 Intent Processing Pipeline
Mission: Frontend differential analysis and UI symptom documentation
CURRENT STATUS: EXECUTION LIMITATION REACHED
✅ COMPLETED TASKS
1. Mandatory Context Verification
- CLAUDE.md methodology: Verified verification-first approach
- shared_types.py enums: All current enums documented
- GitHub issue #172: Verified and updated with investigation status
2. API-Level Differential Testing
- Working prompts:
"hello", "good morning" → 200 OK, <3s response
- Hanging prompts:
"help" → 500 error, "show standup" → timeout >10s
- Pattern confirmed: Simple greetings work, complex/help prompts fail
3. Browser Testing Framework
- Testing script:
web/browser_test_script.js with network monitoring
- Evidence template:
docs/development/phase0-browser-testing-template.md
- Manual protocol: Step-by-step instructions for user execution
⏸️ EXECUTION LIMITATION
CRITICAL CONSTRAINT: I cannot directly interact with the browser interface to execute the manual testing protocol. The framework is complete and ready for user execution.
LIMITATION IMPACT:
- Cannot capture screenshots of UI states
- Cannot interact with browser form elements
- Cannot collect real-time console errors during UI interaction
- Cannot document actual browser timing behavior
📋 EVIDENCE FRAMEWORK READY
Browser Testing Protocol
- Environment: http://localhost:8001 with Developer Tools
- Script: Automated network monitoring and error capture
- Test cases: Working prompts vs hanging prompts
- Evidence collection: Screenshots, console logs, network requests
Expected Evidence Patterns
- Working: UI responds quickly, 200 OK network requests
- Hanging: “Thinking…” state, 500/timeout network requests
🎯 NEXT STEPS REQUIRING USER ACTION
Manual Execution Required
# 1. Open browser at http://localhost:8001
# 2. Open Developer Tools (F12) → Console tab
# 3. Copy/paste web/browser_test_script.js into console
# 4. Follow testing protocol in phase0-browser-testing-template.md
# 5. Collect evidence and return findings
Evidence to Collect
🔄 COORDINATION STATUS
Multi-Agent Strategy
- Cursor Agent (Frontend): Framework ready, awaiting manual execution
- Claude Code (Backend): Separate backend investigation in progress
- Coordination point: Cross-reference UI symptoms with backend patterns
GitHub Issue Status
- Issue #172 updated with frontend investigation start
- Backend investigation by Claude Code documented
- Awaiting frontend evidence collection for final update
EVIDENCE FIRST PRINCIPLE MAINTAINED
Following the mandatory “Evidence First” approach:
- ✅ API-level evidence collected and documented
- ✅ Testing framework created for browser evidence collection
- ⏸️ Browser evidence collection requires user interaction
- ⏸️ Analysis and conclusions pending evidence
SUCCESS CRITERIA STATUS
Phase 0 Goals:
- ✅ Identify which prompts work vs hang
- ⏸️ Document browser errors (framework ready)
- ⏸️ Analyze request differences (framework ready)
- ⏸️ Capture UI symptoms (framework ready)
Deliverables Status:
- ✅ Working vs hanging pattern identified at API level
- ⏸️ Browser evidence pending manual collection
- ⏸️ Console error analysis pending execution
- ⏸️ Network request analysis pending execution
METHODOLOGY COMPLIANCE
✅ Verification First: Context checks completed before starting
✅ Evidence Based: API testing provided concrete evidence
✅ Session Documentation: Continuous log updates maintained
✅ Multi-Agent Coordination: GitHub issue updated for coordination
⏸️ Systematic Testing: Framework ready, execution limited
RECOMMENDATION
IMMEDIATE ACTION: User should execute the manual browser testing protocol to complete Phase 0 evidence collection. All tools and frameworks are prepared and ready for use.
ESTIMATED TIME: 10-15 minutes for manual execution and evidence collection.
NEXT PHASE: Once evidence is collected, I can immediately proceed with analysis, symptom matrix creation, and final GitHub issue update.
