 - **Removed Client Filter Logic**: Removed restrictive source-level noise filtering on edge forwarders. Clients now collect and stream all candidate events from `INFO` up to `ERROR` over the lookback window instead of discarding them at the source.
 - **State Tracking & Deduplication**: Added persistent client state tracking (`client_state.json`) with journalctl cursors and Windows Event Log record numbers to guarantee that previously transmitted events are never resent.
 - **24-Hour Lookback Window**: Forwarders now scan and upload events from the last 24 hours (default `--hours 24`), skipping older entries.
+- **Warning Persistence & Immediate Error Routing**: Restructured temporal verification on the central hub so the 4-run persistence rule across the 12-hour evaluation window strictly governs `WARNING` and `INFO` events to suppress transient blips. High-severity `ERROR`, `CRITICAL`, and `FATAL` events are now promoted to `VERIFIED` immediately on their first occurrence and reported to Hermes without waiting for consecutive runs.
 - **Lightweight Distribution Structure**: Cleaned `out/` to strictly contain deployment documentation and sample configurations.
 - **Automated Gitea CI/CD**: Integrated push testing workflow (`ci.yml`) and multi-platform release asset packaging.
