kevinveenbirkenbachandClaude Opus 4.7 16bdbf03d7 docs: fix repo-wide drift against documentation.md style rules
Three classes of drift cleaned up across 85 .md files:

- Em-dashes: replaced ` — ` with the contextually correct separator
  (colon for `term: explanation`, period to split clauses across
  sentences/source lines, parentheses for asides, semicolon for
  tight-linked continuations). Two intentional exceptions remain
  in `docs/contributing/documentation.md` (the rule literal) and
  inside a fenced ```sh block in `docs/contributing/actions/debugging/ci.md`.
- SPOT self-labels: rewrote "This is the SPOT for X" to describe
  the subject directly ("This directory holds X" / "This file
  describes X"). Cross-references to other artefacts' canonical
  role remain unchanged.
- Heading-emoji position: moved leading-emoji headings (`# 🧩 Title`)
  to trailing position (`# Title 🧩`) per the headline rule that
  emojis MUST come after the title text.

DNS Setup Scripts 🌐

This directory contains platform-specific scripts for setting up local DNS resolution for the infinito.example domain (and subdomains) on the development machine.

All scripts map *.infinito.example → 127.0.0.1 so that local deployments are reachable via their expected hostnames.


Scripts 📄

linux.sh 🐧

General-purpose DNS setup for Linux systems. Supports multiple strategies depending on the environment:

  • NetworkManager + dnsmasq. preferred path when NetworkManager is active; configures the NM dnsmasq plugin with a wildcard zone entry.
  • System dnsmasq. fallback when NetworkManager is not running; configures a standalone dnsmasq service.
  • /etc/hosts fallback. used in non-systemd environments (e.g. Docker containers, LXC) where service management is unavailable; writes a managed block of host entries directly into the hosts file.

Shared helper functions are sourced from ../common.sh.

wsl.sh 🪟

WSL2-specific DNS setup. Only executes when running inside a WSL2 environment (detected via /proc/version). Configures:

  • dnsmasq with the discovered WSL2 upstream DNS gateway as forwarder.
  • systemd-resolved stub listener disabled to avoid port conflicts.
  • /etc/resolv.conf pointed at the local dnsmasq instance (127.0.0.1).
  • /etc/wsl.conf set to generateResolvConf=false to prevent WSL from overwriting the resolver config on restart.
