 **LOGAR** is an enterprise-grade log aggregation, normalization, and centralized provisioning system built for heterogeneous server fleets (Windows & Linux). It pairs ultra-lightweight, zero-state edge forwarders with a secure centralized server hub that enforces mutual TLS 1.3 (**mTLS**) authentication, dynamic PKI fleet licensing with cryptographic seat leasing, 12-hour temporal persistence tracking, and direct anomaly pass-through—delivering clean, structured, verified log telemetry directly to **Hermes AI** for autonomous deep reasoning, contextual root-cause analysis, and operational decision-making.

-# LOGAR Release v0.3.2
+# LOGAR Release Notes
 
-### 🪟 Windows Installer Fixes
+## [v0.3.5.1] - 2026-09-30
-- **Standalone Windows Binaries & Python Runtime**: Resolved issues with standalone Windows executable execution and bundled runtime paths.
+
-- **Data Directory Selection & Permissions**: Added custom data directory selection during setup and fixed permissions for background Windows services.
+### 🗄️ Multi-Engine Storage Architecture
-- **Service Lifecycle & Clean Uninstallation**: Resolved service startup issues and ensured complete cleanup of state files upon uninstallation.
+- **Dynamic Backend Switching**: LOGAR Server Hub supports runtime switching between lightweight Local SQLite (WAL Mode) and Enterprise SQL servers (PostgreSQL and MySQL / MariaDB) via SQLAlchemy.
+- **Automated Schema Provisioning**: Database switching automatically verifies connectivity, provisions normalized tables (`telemetry_events`, `client_seats`, `license_config`, `admin_users`), and generates optimized query indices.
+- **Config Isolation**: Runtime backend parameters are stored persistently in `server_config.json` under `db_engine` and safely isolated from ephemeral test runs.
+
+### ⚡ Ingestion Ring Buffer & Burst Protection
+- **In-Memory Queue Buffering**: Built-in ring buffer with an asynchronous background flusher decoupled from mTLS socket I/O.
+- **Cache Mode**: High-velocity log spikes are absorbed in memory without blocking incoming mTLS 1.3 frame streams.
+- **Configurable Batching**: Configurable flush interval (`buffer_flush_interval_sec`, default 2.0s) and batch size (`buffer_batch_size`, default 100).
+- **Graceful Shutdown**: Unflushed queue items are flushed and committed cleanly during server shutdown.
+- **Opt-In Security Policy**: Buffering remains an explicit administrative choice and is not auto-enabled upon license activation.
+
+### 🔐 Zero-Knowledge OpenPGP Data Encryption at Rest
+- **Public-Key Envelope Encryption**: External SQL payloads (`event_data`) can be encrypted at rest using the server's X.509 RSA-2048 / OpenPGP public key with AES-256-GCM symmetric session keys.
+- **Zero-Knowledge on Database Host**: External DBAs or compromised database hosts cannot read plaintext telemetry without the server's private key.
+- **Opt-In Security Policy**: Payload encryption is strictly opt-in and configurable per compliance requirements.
+
+### 📜 Dynamic Licensing Introspection & Clean Dashboard WebUI
+- **Modular Capability Introspection**: PKI X.509 extension OID `1.3.6.1.4.1.58888.1.3` and persistent license records are dynamically parsed to display active modules (`enterprise_db`, etc.) in a dedicated card on the **📜 Sub-CA & Licensing** tab.
+- **Distraction-Free Tab Navigation**: Cleaned all dashboard tab headers to remove redundant item counts and visual badges for a streamlined administrative interface.
+- **Graceful Feature Locking**: Unlicensed enterprise controls remain visible but gracefully disabled in the WebUI and rejected by backend API validation.
+
+### 🛠️ Dynamic Installer Context Versioning & Streamlined CI/CD
+- **Context-Aware Installer Builds**: NSIS and Inno Setup compiler scripts dynamically derive version information directly from build context/tags (`v0.3.5.1`) without hardcoded version strings.
+- **Pre-Integrated Builder Runner**: Streamlined CI/CD workflows to rely directly on pre-installed container tools and libraries without runtime `apt`/`pip` overhead.
+
+### 📖 WebUI Administrator Guide & 51 Automated Tests
+- **WebUI Administrator Guide**: Published comprehensive WebUI management guide on the [Gitea Wiki](https://gitea.eibl.tech/me0nline/LOGAR/wiki/Admin-Guide) covering console access, telemetry filtering, seat management, licensing, database switching, queue tuning, zero-knowledge crypto, Hermes AI, and 2FA.
+- **Expanded Test Suite**: 51 automated unit and integration tests passing with 100% test coverage.

-# LOGAR Linux Edge Forwarder
-
-Standalone compiled binary and automated systemd service distribution for Linux edge servers.
-
----
-
-## Overview
-`Linux_Client.bin` is a self-contained, pre-compiled executable that queries `systemd-journald` via `journalctl`, filters logs directly at the source, auto-enrolls with the central LOGAR hub, and streams candidate events over mutual TLS 1.3 (**mTLS**) to the central hub.
-
-### Key Capabilities
-- **Pre-compiled & Dependency-Free**: Ships as a standalone native binary (`Linux_Client.bin`). No Python environment, 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 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 `/etc/logar/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` (`journalctl -p warning`). Drops debug noise and skips events older than 24 hours.
-- **State Tracking & Deduplication**: Maintains persistent client state in `client_state.json` (tracking systemd journalctl cursors and microsecond timestamps) so every log record is forwarded exactly once without duplicates.
-- **Fleet Seat Accounting & License Revocation**: Each enrolled client consumes 1 seat from the hub's master license. If revoked by an administrator via the hub WebUI, socket connections are immediately dropped and blocked until reactivated.
-- **Dynamic Seat Expansion & Automatic Hub Synchronization**: The forwarder benefits from the hub's dynamic seat quota expansion; as the hub's license seats are increased and synced with the master authority (`logar.eibl.tech`), edge capacity expands automatically without requiring forwarder configuration changes.
-- **Master Authority High Availability (Portainer GitOps)**: The authoritative license server at `logar.eibl.tech` runs containerized via Portainer GitOps with automated pipeline builds, ensuring high availability for client seat verification and renewals.
-
----
-
-## 1. Automated Installation via Script (Recommended)
-
-Run the automated installer script:
-```bash
-sudo ./compilation/install_linux_client.sh "http://<HUB_HOST>:8443" "<ENROLLMENT_SECRET>"
-```
-This script:
-1. Installs the binary to `/opt/logar-client/Linux_Client`.
-2. Creates `/etc/logar/certs` with strict permissions.
-3. Automatically queries `/etc/machine-id` and enrolls with the hub via `curl`.
-4. Deploys, enables, and starts the systemd service unit `/etc/systemd/system/logar-client.service`.
-
----
-
-## 2. Generating & Deploying the Configuration File
-
-### Step 1: Generate `client_config.json` on the Server
-Run the following command on your central LOGAR server:
-```bash
-python src/Server.py --create-client-config --server-host <SERVER_IP_OR_DNS> --server-port 9443 --client-out client_config.json
-```
-- Replace `<SERVER_IP_OR_DNS>` with the reachable IP address or FQDN of your central LOGAR server hub.
-- Default mTLS socket port is `9443`; Hermes REST API port is `8443`.
-
-### Step 2: Configuration Structure
-The generated `client_config.json` contains:
-```json
-{
-  "server_host": "192.168.1.100",
-  "server_port": 9443,
-  "hermes_host": "192.168.1.100",
-  "hermes_port": 8443,
-  "enrollment_secret": "a1b2c3d4e5f6...",
-  "cert_dir": "certs",
-  "server_fingerprint": "375388960531264EA0648EC0D2C4E4ABC6F22AC2",
-  "server_public_key": "-----BEGIN PGP PUBLIC KEY BLOCK-----\n...",
-  "auth_token": "a1b2c3d4e5f6..."
-}
-```
-
-> [!NOTE]
-> The configuration contains **no host-specific names or site names** to ensure client anonymity and easy redistribution.
-
-### Step 3: Copy to Edge Node
-Place `Linux_Client.bin` and `client_config.json` into the target directory (e.g. `/opt/logar/`):
-```bash
-sudo mkdir -p /opt/logar
-sudo cp Linux_Client.bin client_config.json /opt/logar/
-sudo chmod +x /opt/logar/Linux_Client.bin
-```
-
----
-
-## 3. Running Manually
-
-Test the forwarder interactively:
-```bash
-cd /opt/logar
-./Linux_Client.bin --hours 24
-```
-On first run, the client contacts `http://<hermes_host>:<hermes_port>/api/client/enroll`, downloads `ca.crt`, `client.crt`, and `client.key` into `certs/`, and streams logs over mTLS.
-
-### Command-Line Arguments
-| Argument | Default | Description |
-| :--- | :--- | :--- |
-| `--config` | `client_config.json` | Path to client configuration file |
-| `--hours` | `24` | Lookback window in hours for journal logs |
-| `--state-file` | `client_state.json` | Path to persistent state file |
-| `--no-state` | `False` | Disable state tracking and send all events matching lookback window |
-
----
-
-## 4. Manual Systemd Service & Timer Setup
-
-### Step 1: Create the Systemd Service Unit
-Create `/etc/systemd/system/logar-client.service`:
-```ini
-[Unit]
-Description=LOGAR Edge Log Forwarder
-After=network-online.target
-Wants=network-online.target
-
-[Service]
-Type=simple
-WorkingDirectory=/opt/logar
-ExecStart=/opt/logar/Linux_Client.bin --hours 24
-Restart=always
-RestartSec=5s
-User=root
-StandardOutput=journal
-StandardError=journal
-
-[Install]
-WantedBy=multi-user.target
-```
-
-### Step 2: Enable and Start the Service
-```bash
-sudo systemctl daemon-reload
-sudo systemctl enable --now logar-client.service
-```
-
-### Step 3: Check Logs
-```bash
-sudo journalctl -u logar-client.service -n 50 -f
-```
-
----
-
-## 5. Uninstallation & Removal
-
-```bash
-sudo systemctl disable --now logar-client.service
-sudo rm -f /etc/systemd/system/logar-client.service
-sudo systemctl daemon-reload
-sudo rm -rf /opt/logar-client /opt/logar /etc/logar

-# LOGAR Linux Server Hub
-
-Standalone compiled binary and automated systemd service distribution for Linux server environments (`Server.bin`).
-
----
-
-## Overview
-
-`Server.bin` is a self-contained, pre-compiled Linux ELF executable that operates as the central coordination, log analysis, dynamic PKI, and reporting hub of the LOGAR telemetry architecture.
-
-### Key Architecture & Capabilities
-- **Pre-compiled & Dependency-Free**: Ships as a standalone native Linux ELF binary (`Server.bin`). No Python runtime, pip dependencies, or GnuPG binaries are required on the host system.
-- **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 Subordinate CA and verifies active licensing in SQLite.
-- **Master License Authority (`logar.eibl.tech`) & Seat-Bearing CA**: Integrates with the upstream authority. Subordinate CA certificates embed exact seat quotas via custom enterprise X.509 OID `1.3.6.1.4.1.59999.1.1`.
-- **Zero-Touch mTLS Renewals**: Once initial signed CA cert is imported, the server hub automatically executes in-flight mTLS renewals with `https://logar.eibl.tech/api/license/renew` when nearing expiration (< 30 days).
-- **Fleet Management & WebUI Dashboard (Port 8443)**: Modern browser WebUI accessible at `http://localhost:8443/webui` to monitor seat quotas, export `.lic` request files, copy CA CSRs, activate signed CA certs, and revoke/reactivate forwarder seats with immediate socket enforcement.
-- **Direct Hermes Intelligence & Temporal Telemetry**: All ingested actionable anomalies (`WARNING`, `ERROR`, `INFO`) are immediately promoted to `VERIFIED` and surfaced directly to Hermes with rich temporal metadata (run counts, timestamps) across a rolling 12-hour evaluation window, allowing Hermes AI to perform all contextual reasoning and decisions.
-- **Embedded Hermes Reporting 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`).
-
----
-
-## 1. Automated Installation via Script (Recommended)
-
-Deploy using the automated installer:
-```bash
-sudo ./compilation/install_linux_server.sh
-```
-This script:
-1. Installs the server binary to `/opt/logar-server/Server`.
-2. Creates `/etc/logar` and `/var/log/logar`.
-3. Deploys, enables, and starts the systemd service unit `/etc/systemd/system/logar-server.service` with `LimitNOFILE=65536`.
-
----
-
-## 2. Initializing & Generating Server Configuration
-
-### Step 1: Automatic First-Run Generation
-When launched without an existing `server_config.json`, `Server.bin` automatically generates:
-1. An internal Root CA (`certs/ca.crt` and `certs/ca.key`).
-2. A server TLS certificate (`certs/server.crt` and `certs/server.key`) with SANs.
-3. An OpenPGP RSA-2048 keypair (`private_key` and `public_key`).
-4. Cryptographically random authentication tokens and enrollment secrets.
-5. Default network socket coordinates (mTLS 9443, Hermes API 8443).
-
-Run `Server.bin` once to initialize:
-```bash
-./Server.bin
-```
-Output:
-```
-[!] Config 'server_config.json' not found. Initializing first-run configuration...

-  "public_key": "-----BEGIN PGP PUBLIC KEY BLOCK-----\n...",
-  "private_key": "-----BEGIN PGP PRIVATE KEY BLOCK-----\n..."
-}
-```
-
----
-
-## 3. Exporting Client Configurations
-
-Generate a client configuration bundle to deploy onto Windows or Linux forwarders:
-```bash
-./Server.bin --create-client-config --server-host 192.168.1.100 --server-port 9443 --client-out client_config.json
-```
-The output file contains the server coordinates, enrollment secret, and fingerprint, ready for client deployment.
-
----
-
-## 4. Fleet Licensing, .lic Files & WebUI Dashboard
-
-### Accessing the WebUI
-Open your browser and navigate to:
-```
-http://<SERVER_IP>:8443/webui
-```
-The WebUI provides:
-1. **Real-time Seat Quota Meter**: Visual meter displaying active clients against approved seat quota.
-2. **Export .lic Request**: 1-click download of `logar_server.lic` containing your Subordinate CA CSR and machine fingerprint for `logar.eibl.tech`.
-3. **Import License (.lic / ca.crt)**: Modal to paste or upload the activated `.lic` package or `ca.crt` issued by `logar.eibl.tech`. Activating updates your seat limit immediately and reloads mTLS context in-flight.
-4. **Sync & Renew via mTLS**: Button to test or trigger immediate mTLS renewal against `logar.eibl.tech` and pull seat quota increases without restart.
-5. **Client Seat Management**: View all enrolled nodes; click **Revoke Seat** to immediately drop and block an edge node at the socket layer, or **Reactivate** to restore access.
-
-### CLI Licensing Utilities
-Export a `.lic` request file via CLI:
-```bash
-./Server.bin --export-lic server.lic
-```
-Import an activated `.lic` license package or signed CA certificate via CLI:
-```bash
-./Server.bin --import-lic activated.lic
-# Or alternatively with --import-ca:
-./Server.bin --import-ca ca.crt
-```
-Synchronize license and check for seat quota increases against the master authority:
-```bash
-./Server.bin --sync-license
-```
-
-### Upstream Authority Deployment (Portainer GitOps & Reverse Proxy)
-The upstream Master License Authority service (`logar.eibl.tech`) is compiled and deployed via Portainer GitOps from the [`LOGAR-LICENSING`](https://gitea.eibl.tech/me0nline/LOGAR-LICENSING.git) repository, running from `gitea.eibl.tech/me0nline/logar-licensing:latest` with automated pipeline compilation and persistent volume storage. Public traffic passes through a reverse proxy (e.g., Nginx Proxy Manager with **Websockets Support** enabled), handling WebSocket licensing handshakes (`wss://logar.eibl.tech/ws/license`), multi-tenant fleet isolation, user management, and authenticated WebUI dashboard access.
-
----
-
-## 5. Manual Systemd Service Management
-
-Check service status:
-```bash
-sudo systemctl status logar-server.service
-```
-
-Inspect live service logs:
-```bash
-sudo journalctl -u logar-server.service -f -n 50
-```
-
----
-
-## 6. Uninstallation & Removal

-# LOGAR Windows Edge Forwarder
-
-Standalone compiled executable and installer distribution for Windows Server and workstation environments.
-
----
-
-## Overview
-`Win_Client.exe` is a self-contained executable that queries the Windows Application Event Log, filters candidate events at the source, auto-enrolls with the central LOGAR hub to receive signed mTLS certificates, and streams records over mutual TLS 1.3 (**mTLS**) socket connection.
-
-### Key Capabilities
-- **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.

-- **Fleet Seat Accounting & License Revocation**: Each enrolled client consumes 1 seat from the hub's master license. If revoked by an administrator via the hub WebUI, socket connections are immediately dropped and blocked until reactivated.
-- **Dynamic Seat Expansion & Automatic Hub Synchronization**: The forwarder benefits from the hub's dynamic seat quota expansion; as the hub's license seats are increased and synced with the master authority (`logar.eibl.tech`), edge capacity expands automatically without requiring forwarder configuration changes.
-- **Master Authority High Availability (Portainer GitOps)**: The authoritative license server at `logar.eibl.tech` runs containerized via Portainer GitOps with automated pipeline builds, ensuring high availability for client seat verification and renewals.

-## 1. Automated Installation via Inno Setup (Recommended)
-
-Run the self-contained installer built from `compilation/installer_client.iss`:
-```powershell
-.\LOGAR-Client-Setup.exe
-```
-This installer:
-1. Installs `Win_Client.exe` and bundled `nssm.exe` to `C:\Program Files\LOGAR\`.
-2. Sets up directory permissions in `C:\ProgramData\LOGAR\`.
-3. Registers and starts the `LOGAR_Client` Windows service automatically via NSSM.
-4. Redirects stdout and stderr logs to `C:\ProgramData\LOGAR\client.log` and `client_err.log`.
-
----
-
-## 2. Generating & Deploying the Configuration File
-
-### Step 1: Generate `client_config.json` on the Server
-Run the following command on your central LOGAR server:
-```bash
-python src/Server.py --create-client-config --server-host <SERVER_IP_OR_DNS> --server-port 9443 --client-out client_config.json
-```
-- Replace `<SERVER_IP_OR_DNS>` with the reachable IP address or FQDN of your central LOGAR server hub.
-- Default mTLS socket port is `9443`; Hermes REST API port is `8443`.
-
-### Step 2: Configuration Structure
-The generated `client_config.json` contains:
-```json
-{
-  "server_host": "192.168.1.100",
-  "server_port": 9443,
-  "hermes_host": "192.168.1.100",
-  "hermes_port": 8443,
-  "enrollment_secret": "a1b2c3d4e5f6...",
-  "cert_dir": "certs",
-  "server_fingerprint": "375388960531264EA0648EC0D2C4E4ABC6F22AC2",
-  "server_public_key": "-----BEGIN PGP PUBLIC KEY BLOCK-----\n...",
-  "auth_token": "a1b2c3d4e5f6..."
-}
-```
-
-> [!NOTE]
-> The configuration contains **no host-specific names or site names** to ensure client anonymity and easy redistribution.
-
-### Step 3: Copy to Edge Node
-Place `client_config.json` next to `Win_Client.exe` (e.g. `C:\Program Files\LOGAR\` or `C:\LOGAR\`):
-```powershell
-New-Item -ItemType Directory -Path "C:\LOGAR" -Force
-Copy-Item "Win_Client.exe", "client_config.json" -Destination "C:\LOGAR\"
-```
-
----
-
-## 3. Running Manually
-
-Test the forwarder interactively from PowerShell or Command Prompt:
-```powershell
-cd C:\LOGAR
-.\Win_Client.exe --hours 24
-```
-On first run, the client contacts `http://<hermes_host>:<hermes_port>/api/client/enroll`, downloads `ca.crt`, `client.crt`, and `client.key` into `certs/`, and streams logs over mTLS.
-
-### Command-Line Arguments
-| Argument | Default | Description |
-| :--- | :--- | :--- |
-| `--config` | `client_config.json` | Path to client configuration file |
-| `--hours` | `24` | Lookback window in hours for event logs |
-| `--state-file` | `client_state.json` | Path to persistent state tracking file |
-| `--no-state` | `False` | Disable state tracking and send all events matching lookback window |
-

-```
-
-### Method B: Windows Scheduled Task via PowerShell
-```powershell
-$Action = New-ScheduledTaskAction -Execute "C:\LOGAR\Win_Client.exe" -Argument "--hours 24" -WorkingDirectory "C:\LOGAR"
-$Trigger = New-ScheduledTaskTrigger -Once -At (Get-Date) -RepetitionInterval (New-TimeSpan -Hours 3)
-$Settings = New-ScheduledTaskSettingsSet -AllowStartIfOnBatteries -DontStopIfGoingOnBatteries -StartWhenAvailable -ExecutionTimeLimit (New-TimeSpan -Minutes 15)
-
-Register-ScheduledTask -TaskName "LOGAR_Forwarder" `
-                       -Action $Action `
-                       -Trigger $Trigger `
-                       -Settings $Settings `
-                       -User "NT AUTHORITY\SYSTEM" `
-                       -RunLevel Highest `
-                       -Description "LOGAR Windows Edge Log Forwarder Service"
-
-Start-ScheduledTask -TaskName "LOGAR_Forwarder"
-```
-
----

-# LOGAR Windows Server Hub
-
-Standalone compiled executable and installer distribution for Windows Server environments (`Server.exe`).
-
----
-
-## Overview
-
-`Server.exe` is a self-contained, pre-compiled native Windows PE executable that serves as the central log aggregation, temporal persistence analyzer, dynamic PKI certificate authority, and reporting hub of the LOGAR infrastructure.
-
-### Key Architecture & Capabilities
-- **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 Subordinate CA and verifies active licensing in SQLite.
-- **Master License Authority (`logar.eibl.tech`) & Seat-Bearing CA**: Integrates with the upstream authority. Subordinate CA certificates embed exact seat quotas via custom enterprise X.509 OID `1.3.6.1.4.1.59999.1.1`.
-- **Zero-Touch mTLS Renewals**: Once initial signed CA cert is imported, the server hub automatically executes in-flight mTLS renewals with `https://logar.eibl.tech/api/license/renew` when nearing expiration (< 30 days).
-- **Fleet Management & WebUI Dashboard (Port 8443)**: Modern browser WebUI accessible at `http://localhost:8443/webui` to monitor seat quotas, export `.lic` request files, copy CA CSRs, activate signed CA certs, and revoke/reactivate forwarder seats with immediate socket enforcement.
-- **Direct Hermes Intelligence & Temporal Telemetry**: All ingested actionable anomalies (`WARNING`, `ERROR`, `INFO`) are immediately promoted to `VERIFIED` and surfaced directly to Hermes with rich temporal metadata (run counts, timestamps) across a rolling 12-hour evaluation window, allowing Hermes AI to perform all contextual reasoning and decisions.
-- **Embedded Hermes Reporting 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`).

-## 1. Automated Installation via Inno Setup (Recommended)
-
-Run the self-contained installer built from `compilation/installer_server.iss`:
-```powershell
-.\LOGAR-Server-Setup.exe
-```
-This installer:
-1. Installs `Server.exe` and bundled `nssm.exe` to `C:\Program Files\LOGAR-Server\`.
-2. Registers and starts the `LOGAR_Server` Windows service automatically via NSSM.
-3. Redirects stdout and stderr logs to `C:\ProgramData\LOGAR-Server\server.log` and `server_err.log`.
-
----
-
-## 2. Initializing & Generating Server Configuration
-
-### Step 1: Automatic First-Run Generation
-When launched without an existing `server_config.json`, `Server.exe` automatically initializes:
-1. An internal Root CA (`certs/ca.crt` and `certs/ca.key`).
-2. A server TLS certificate (`certs/server.crt` and `certs/server.key`) with SANs.
-3. An OpenPGP RSA-2048 keypair (`private_key` and `public_key`).
-4. Cryptographically random authentication tokens and enrollment secrets.
-5. Default network socket coordinates (mTLS 9443, Hermes API 8443).
-
-Open PowerShell and run:
-```powershell
-.\Server.exe
-```
-Output:
-```
-[!] Config 'server_config.json' not found. Initializing first-run configuration...
-[+] Successfully generated new server config and OpenPGP keypair.
-[+] Server Encryption Fingerprint: 375388960531264EA0648EC0D2C4E4ABC6F22AC2

-[*] Client Enrollment API available at http://0.0.0.0:8443/api/client/enroll
-```
-
-### Step 2: Configuration Fields Reference
-The generated `server_config.json` contains:
-```json
-{
-  "server_name": "LOGAR-Windows-Hub",
-  "tcp_host": "0.0.0.0",
-  "tcp_port": 9443,
-  "hermes_host": "0.0.0.0",
-  "hermes_port": 8443,

-  "enrollment_secret": "e1f2a3b4c5d6...",
-  "max_seats": 10,
-  "cert_dir": "certs",
-  "tls_enabled": true,

-  "public_key": "-----BEGIN PGP PUBLIC KEY BLOCK-----\n...",
-  "private_key": "-----BEGIN PGP PRIVATE KEY BLOCK-----\n..."
-}
-```
-
----
-
-## 3. Exporting Client Configurations
-
-Generate a client configuration bundle to deploy onto Windows or Linux forwarders:
-```powershell
-.\Server.exe --create-client-config --server-host 192.168.1.100 --server-port 9443 --client-out client_config.json
-```
-The output file contains the server coordinates, enrollment secret, and fingerprint, ready for client deployment.
-
----
-
-## 4. Fleet Licensing, .lic Files & WebUI Dashboard
-
-### Accessing the WebUI
-Open your browser and navigate to:
-```
-http://localhost:8443/webui
-```
-The WebUI provides:
-1. **Real-time Seat Quota Meter**: Visual meter displaying active clients against approved seat quota.
-2. **Export .lic Request**: 1-click download of `logar_server.lic` containing your Subordinate CA CSR and machine fingerprint for `logar.eibl.tech`.
-3. **Import License (.lic / ca.crt)**: Modal to paste or upload the activated `.lic` package or `ca.crt` issued by `logar.eibl.tech`. Activating updates your seat limit immediately and reloads mTLS context in-flight.
-4. **Sync & Renew via mTLS**: Button to test or trigger immediate mTLS renewal against `logar.eibl.tech` and pull seat quota increases without restart.
-5. **Client Seat Management**: View all enrolled nodes; click **Revoke Seat** to immediately drop and block an edge node at the socket layer, or **Reactivate** to restore access.
-
-### CLI Licensing Utilities
-Export a `.lic` request file via CLI:
-```powershell
-.\Server.exe --export-lic C:\LOGAR-Server\server.lic
-```
-Import an activated `.lic` license package or signed CA certificate via CLI:
-```powershell
-.\Server.exe --import-lic C:\LOGAR-Server\activated.lic
-# Or alternatively with --import-ca:
-.\Server.exe --import-ca C:\LOGAR-Server\ca.crt
-```
-Synchronize license and check for seat quota increases against the master authority:
-```powershell
-.\Server.exe --sync-license
-```
-
-### Upstream Authority Deployment (Portainer GitOps & Reverse Proxy)
-The upstream Master License Authority service (`logar.eibl.tech`) is compiled and deployed via Portainer GitOps from the [`LOGAR-LICENSING`](https://gitea.eibl.tech/me0nline/LOGAR-LICENSING.git) repository, running from `gitea.eibl.tech/me0nline/logar-licensing:latest` with automated pipeline compilation and persistent volume storage. Public traffic passes through a reverse proxy (e.g., Nginx Proxy Manager with **Websockets Support** enabled), handling WebSocket licensing handshakes (`wss://logar.eibl.tech/ws/license`), multi-tenant fleet isolation, user management, and authenticated WebUI dashboard access.
-
----
-
-## 5. Manual Windows Service Setup (via NSSM)
-
-```powershell
-.\nssm.exe install LOGAR_Server "C:\LOGAR-Server\Server.exe"
-.\nssm.exe set LOGAR_Server AppDirectory "C:\LOGAR-Server"
-.\nssm.exe set LOGAR_Server AppStdout "C:\ProgramData\LOGAR-Server\server.log"
-.\nssm.exe set LOGAR_Server AppStderr "C:\ProgramData\LOGAR-Server\server_err.log"
-.\nssm.exe start LOGAR_Server
-```
-
----
-
-## 6. Uninstallation
-
-If installed via the Inno Setup installer, use **Windows Add/Remove Programs**.
