📊 Market-Rover System Status Report

Date: January 7, 2026 Overall Status: ✅ HEALTHY Log Analysis Decision: No critical "ERROR" logs found for today (2026-01-07).

1. Resolved Issues (Confirmed via Logs & Verification)

Issue / Error Pattern	Diagnostics	Status	Fix Implemented
System Health Crash	`KeyError: ['status'] not in index`	✅ Fixed	Added default handling for missing status columns in `system_health.py`.
Profile Navigation Lock	User stuck in Profile tab; "Save" not unlocking app.	✅ Fixed	Added state update hook `user_profile_mgr.update_profile_timestamp()` on save.
Simulation Graph Failure	Empty Graph / Silent Failure	✅ Fixed	Replaced erratic tickers (ZOMATO, LIQUIDBEES) with reliable proxies (GOLDBEES, TRENT) in `investor_profiler.py`.
API Data Gaps	`yfinance` returning "No Data" or "Empty DataFrame"	✅ Fixed	Switched invalid ETF proxies to high-volume liquid equivalents.
UI Version mismatch	"Market-Rover 2.0" labels	✅ Fixed	Updated all UI references to generic "Market-Rover" or "4.1".

Application Log (logs/market_rover.log):
- ERROR count (Today): 0
- FAILED count (Today): 0
- Observation: The backend appears stable. Previous download errors related to the Simulation tab have ceased.
System Health (metrics/workflow_events_*.jsonl):
- Stability Score: 100% (No emergency overrides triggered today).
- Success Rate: Previous session failures (due to the KeyError) should stem from historical data; new sessions are completing successfully.

While no critical errors are active, the following are items to watch:

Item	Priority	Note
API Rate Limiting	Low	`RateLimiter` is active. Occasional logs about "Rate limit hit" are expected behavior, not bugs.
Network Flakiness	Low	`yfinance` partially depends on Yahoo API availability. Occasional connection timeouts may occur (handled by retry logic).
Browser Cache	Low	Users might need to "Hard Refresh" (Ctrl+F5) to see the new labels and button fixes.

Next Steps:

Monitor the System Health tab for the next 24 hours to ensure the "Success Rate" trends up.
Report any "Toast Notifications" regarding missing tickers via the new debug_simulation_v2.py script if needed.
