VPSMaster Known Limitations — 1.0 public Beta

• Targets: Ubuntu22.04+ / Python3.10+. Available labs: existing Ubuntu22 Desktop with fresh HOME, Ubuntu24 Server. No new Ubuntu22 Server, overseas VPS or ARM acceptance implied.
• Kernel text consoles default to English. Explicit Chinese needs suitable fonts.
• Missing commands, permissions, quotas, certificates or filtering can yield unknown/partial.
• One response per TTL is router-response evidence, not forwarding loss. IP geography is an estimate. ASN/operator can be unavailable; trace enrichment caps at 12 public lookups.
• No proof of dedicated hardware, complete reputation, mail deliverability, playback, full China routes, commercial BGP relationships or line capacity.
• China bandwidth candidates are optional, not a validated complete mainland set. Hong Kong never substitutes for mainland Mobile. No remote scripts execute.
• Default checks do not change SSH, firewall, DNS or routes. Installation creates a user venv; reports create local files; opt-in bandwidth sends bounded test payloads.
• Sharing redacts known patterns, not arbitrary text. Review exports; raw journals, inventories, credentials, snapshots and backups must remain private.
• Reports do not expire automatically. Third-party data retention/sharing terms remain applicable; see docs/DATA_SERVICES.md, including IP2Location cache limits.
• The manifest detects file changes, not publisher authenticity. Verify the ZIP digest through a trusted independent channel before installation.
• Media checks cover public-page reachability only, not unlock or paid playback.
• Mainland three-carrier speed testing is experimental and disabled by default.
• Public IPv6 and complete public ICMP/TCP routes are not comprehensively accepted.
• Beta is not production stability or an independent security certification.
• No Web UI, automatic proxy deployment or full management panel is provided.
• Bandwidth attempted counts scheduled sample slots, including automatically skipped slots; it is not an actual network-request counter. Inspect sample errors.

当前不具备一键安全加固或自动修复。未来遵循检测→解释→预览→确认→备份→执行→验证→回滚；回滚不能覆盖所有断网/重启/云安全组/宿主机故障。本轮只更新路线与私有发布准备。
