The plan and decisions Q105 to Q116 (docs/milestones/S1.md). lib/net: strict IPv4 parsing, prefix and mask, and the checks a Fixed setting must pass, each refusal with its reason. A Saved Network is Automatic or Fixed (address/prefix and an optional gateway), kept with it in flash. Settings: two DNS servers (9.9.9.9, 1.1.1.1), "Always use my DNS", two NTP servers (pool.ntp.org, time.cloudflare.com). Host-tested: 383 tests.
