 - **Pre-compiled & Dependency-Free**: Ships as a standalone Windows executable (`Server.exe`) or full installer (`LOGAR-Server-Setup.exe`). No Python installation, pip packages, or GnuPG binaries are required on Windows Server.
 - **Mutual TLS 1.3 (mTLS) Ingestion (Port 9443)**: Enforces mutual TLS 1.3 authentication for all incoming edge connections. Validates client certificates against an internal Root CA and verifies active licensing in SQLite.
 - **Dynamic PKI & License Accounting**: Built-in Root CA generates server TLS certificates with SANs and dynamically signs client certificates via `POST /api/client/enroll` while enforcing seat limits (`max_seats`).
+- **In-Flight Certificate Watchdog & Dynamic Reloading**: Continuously monitors Root CA (`ca.crt`) and Server TLS certificate (`server.crt`) validity in the background (every 12 hours). When nearing expiration (< 30 days), certificates are automatically regenerated with timestamped backups, and active `ssl.SSLContext` structures are reloaded dynamically without dropping socket connections or restarting the Windows service.
 - **Warning Persistence & Immediate Error Routing**: High-severity `ERROR`, `CRITICAL`, and `FATAL` events are promoted to `VERIFIED` immediately on their first occurrence. Operational `WARNING` and `INFO` events require persistence across at least 4 distinct transmission cycles within a rolling 12-hour evaluation window.
 - **Embedded Hermes Reporting & Management API (Port 8443)**: Integrated REST API exposing `/api/hermes/report`, `/api/clients`, and `/api/client/enroll`.
 - **State Database**: Stores issue lifecycle records, client telemetry, and licensing quotas in a local SQLite database (`logar_state.db`).
