-🎯 What: Add a comprehensive test file for `sync_gemini_token.py`.
-📊 Coverage: Added tests covering the happy path (successful retrieval and parsing of credentials with nanosecond/offset handling), error conditions (secret-tool failure, empty output), edge cases for bad JSON (missing token key, missing access token), and exception handling (date parsing fallback, general exceptions).
-✨ Result: `sync_gemini_token.py` is now fully covered by tests, ensuring its logic handles all expected scenarios correctly.
+🎯 **What:** The `_memory_entry` helper function in `router/memory_mcp.py` was previously completely untested. This function is responsible for converting a raw dictionary representation of a memory entry from LiteLLM into a structured dictionary used by the MCP.
+
+📊 **Coverage:** The new `test_memory_mcp.py` file covers several scenarios for the `_memory_entry` dictionary translation helper:
+- **Happy Path:** Tests that valid and complete memory dictionaries are properly parsed, mapped, and typed.
+- **Invalid Key:** Verifies that if a memory has a key that does not start with `"memory:"`, the function properly returns `None`.
+- **Malformed/String Value:** Tests the graceful fallback when a memory value is a raw string instead of the expected JSON payload, ensuring it still parses the string into the `data` field and initializes an empty `tags` array without throwing a JSON decode error.
+- **Missing Fields:** Tests dictionary inputs that are missing either `"key"` or `"value"` or both to ensure graceful behavior, fallback values, and early exits without `KeyError`s.
+
+✨ **Result:** Increased code reliability and coverage for the core memory data transformation logic with pure, isolated dictionary tests ensuring zero runtime side effects.

 ## 2026-06-24 - Async Offloading for SQLite I/O
 **Learning:** Synchronous blocking I/O (like SQLite queries) inside an async event loop handler can cause significant latency spikes and block other requests.
 **Action:** Use `asyncio.to_thread()` to offload synchronous database interactions to a worker thread, ensuring the main event loop remains responsive.
+## 2026-06-24 - [Performance Improvement] Offload synchronous file I/O in async functions
+
+**Learning:** When making code optimizations within async functions, avoid creating standalone tasks (`asyncio.create_task()`) for synchronous functions that execute blocking I/O if the return isn't needed, as this can trigger Task destruction errors, swallow exceptions, or throw RuntimeErrors if called outside of the main event loop context.
+
+**Action:** Always prefer wrapping the blocking function call directly using `await asyncio.to_thread(func, args)` at the caller site within the async context rather than wrapping the synchronous function definition itself. This maintains safe concurrent behavior while avoiding task lifecycle/GC issues and event loop errors.

-## 2024-06-16 - Synchronous I/O in Async API Handlers
-**Learning:** `save_persisted_stats()` was being called synchronously on every API request, cache hit, and tool usage log, triggering blocking disk I/O in the main event loop.
-**Action:** Always throttle or batch background telemetry writes in async Python applications to prevent blocking the event loop under load.
-
-## 2026-06-24 - Async Offloading for SQLite I/O
-**Learning:** Synchronous blocking I/O (like SQLite queries) inside an async event loop handler can cause significant latency spikes and block other requests.
-**Action:** Use `asyncio.to_thread()` to offload synchronous database interactions to a worker thread, ensuring the main event loop remains responsive.
-## 2026-06-24 - [Performance Improvement] Offload synchronous file I/O in async functions
-
-**Learning:** When making code optimizations within async functions, avoid creating standalone tasks (`asyncio.create_task()`) for synchronous functions that execute blocking I/O if the return isn't needed, as this can trigger Task destruction errors, swallow exceptions, or throw RuntimeErrors if called outside of the main event loop context.
-
-**Action:** Always prefer wrapping the blocking function call directly using `await asyncio.to_thread(func, args)` at the caller site within the async context rather than wrapping the synchronous function definition itself. This maintains safe concurrent behavior while avoiding task lifecycle/GC issues and event loop errors.

-🎯 **What:** The `_memory_entry` helper function in `router/memory_mcp.py` was previously completely untested. This function is responsible for converting a raw dictionary representation of a memory entry from LiteLLM into a structured dictionary used by the MCP.
+🎯 **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:** The new `test_memory_mcp.py` file covers several scenarios for the `_memory_entry` dictionary translation helper:
-- **Happy Path:** Tests that valid and complete memory dictionaries are properly parsed, mapped, and typed.
-- **Invalid Key:** Verifies that if a memory has a key that does not start with `"memory:"`, the function properly returns `None`.
-- **Malformed/String Value:** Tests the graceful fallback when a memory value is a raw string instead of the expected JSON payload, ensuring it still parses the string into the `data` field and initializes an empty `tags` array without throwing a JSON decode error.
-- **Missing Fields:** Tests dictionary inputs that are missing either `"key"` or `"value"` or both to ensure graceful behavior, fallback values, and early exits without `KeyError`s.
+📊 **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:** Increased code reliability and coverage for the core memory data transformation logic with pure, isolated dictionary tests ensuring zero runtime side effects.
+✨ **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.
