-🎯 **What:**
-The testing gap addressed is the lack of unit tests for the `get_pie_chart_gradient` visualization utility in `router/main.py`. This utility generates a CSS conic gradient based on global state (`stats["tool_tokens"]`).
+🎯 **What:** The `src_badge` string formatting function in `router/main.py` lacked direct unit testing. Because it dynamically generates UI-facing HTML based on label and color strings, tests are critical for protecting its styling against silent regressions.
 
-📊 **Coverage:**
-What scenarios are now tested:
-- Generation of an empty gradient when all tool counts are zero.
-- Proper fallback assignment of an unknown tool fallback color `#94a3b8`.
-- 100% boundary scenarios for single tool distributions.
-- Variable percentage tracking across multiple distinct concurrent tools.
-
-✨ **Result:**
-The improvement in test coverage isolates the gradient calculation logic via global state monkeypatching using pytest features, providing a safety net to visualize token distributions correctly within the UI dashboards.
+📊 **Coverage:** A new test suite (`test_src_badge.py`) was created, verifying:
+- Happy path output formatting.
+- Empty label injection handling.
+- Special character inclusion logic.
+- Exact full string match of generated HTML (verifying structural rules and styling components).
 
+✨ **Result:** Enhanced test coverage around the UI string generating utility. The function's deterministic string output is now thoroughly protected by test cases. No regressions were introduced into the remaining suite.
