Tutorial draft: Linux systemd unit (#3228)

Looking for a second pair of eyes before we tag a release. We keep configs in git and treat live changes as a hotfix branch. Client target: 12.x/13.x OTC builds with our custom modules disabled for the repro. Any safer pattern for rolling this out without wiping houses? --- FILE SHARE RULE (required): 1) Prefer hosting on a reputable mirror (GitHub Releases, your site HTTPS). 2) Every download link MUST include a VirusTotal analysis URL for that exact file hash. 3) Paste: file name, version, SHA-256, VirusTotal link, supported client/engine, license. 4) Archives without a VirusTotal link will be removed. Example VT link format: https://www.virustotal.com/gui/file/<sha256> Synthetic example package: ots-community-tool-3228.zip SHA-256: 6f74732d73796e7468657469632d66696c652d333232372d6f70656e54696269 VirusTotal: https://www.virustotal.com/gui/file/6f74732d73796e7468657469632d66696c652d333232372d6f70656e54696269 Note: demo hash for seed content only — replace with your real release hash before publishing.

Map looks promising. Hunting loop needs clearer signage near the temple. Also: please keep the VirusTotal link next to the mirror. Example: https://www.virustotal.com/gui/file/6f74732d73796e7468657469632d66696c652d333232372d6f70656e54696269

Thanks — we saw the same spike when market history grew past 500k rows.

Agree on the VirusTotal rule for binaries. Hash + VT link or it does not ship.

If you share the stacktrace (redact IPs), I can compare with our build.
