+Act as a Senior Technical Program Manager. I need to update the `README.md` for my 'Workday-MCP' project to serve as a high-visibility Status Page. 
+
+**CONTEXT:**
+- We just moved from a single-file script to a modular architecture (`server.py` + `lib/data.py`).
+- We have 3 operational tools: `get_worker_status`, `get_worker_manager`, and `scan_manager_mismatches`.
+- Current Goal: WIS-017 (Manager Mismatch Detection) is prototyped and functional with 9 mock records.
+- Next Milestone: WIS-008 (Transitioning from Mock to Real Workday API).
+
+**REQUIREMENTS:**
+1. **Visual Status:** Use a "Traffic Light" system for project components:
+   - 🟢 Green: Functional/Production-Ready
+   - 🟡 Yellow: In Progress/Development
+   - 🔴 Red: Blocked/Not Started
+2. **Standardization:** Ensure the README reflects our "Discipline Drives Quality" pillar (e.g., mention Type Hinting, Pylance-zero-error status, and modular structure).
+3. **Sprint Alignment:** Reference the WIS (Workday Integration Suite) IDs to maintain traceability to our 2026 roadmap.
+4. **Readability:** Use clean Markdown tables and bold headers for scannability.
