 - **Pre-compiled & Dependency-Free**: Ships as a standalone native Windows executable (`Win_Client.exe`) or full installer (`LOGAR-Client-Setup.exe`). No Python installation, pip packages, or GnuPG binaries are required on the host.
 - **Mutual TLS 1.3 (mTLS) Ingestion**: Streams directly over hardware-authenticated TLS 1.3 sockets with hardware/machine-bound client certificates.
 - **Automated Client Enrollment**: On first run with an `enrollment_secret`, the client automatically calls `POST /api/client/enroll` on the hub, saves its certificates into `certs/`, and establishes secure mTLS streaming.
+- **Proactive Expiry Check & Reactive Self-Healing**: Before each run, the client evaluates `client.crt` validity. If within 30 days of expiry, it automatically contacts the hub to renew certificates. If the server Root CA rotates or a TLS handshake error occurs, the client catch-heals by re-enrolling immediately and re-establishing connection without human intervention.
 - **Source-Level Filtering**: Retains events spanning `INFO`, `WARNING`, and `ERROR`. Strips audit events and debug noise, skipping events older than 24 hours.
 - **State Tracking & Deduplication**: Maintains persistent client state in `client_state.json` (tracking event record numbers and timestamp signatures) so every log record is forwarded exactly once without duplicates.
 - **Fail-Safe State Commit**: State is committed only when the server returns a verified `success` response. In the event of a network outage, state remains unchanged and unsent events are retried automatically on the next run.
