Johnathan Corgan 784e22ab1f Merge branch 'master' into next
Forward-merge the v0.4.0 pre-release content (dependency refresh, CI
deb-install + AUR-build legs, docs refresh, doc-comment fixes, and the
Phase 4 source-content squash: CHANGELOG, release notes, README,
fips.yaml, Cargo.toml metadata, reference docs) up the one-way flow.

Conflict fixups (keep next's identity, fold in master's improvements):
- Version: keep next's 0.5.0-dev (Cargo.toml/lock).
- README status: keep next's v0.5.0-dev / wire-format-breaking framing
  and the Breaking-section pointer; fold in the Nym transport and the
  "global, public test mesh of thousands of nodes" description.
- docs/reference/cli-fips.md: keep next's 0.5.0-dev version example.
- CHANGELOG: keep next's XX-handshake admission entry (no early cap gate
  on XX) and drop master's IK early-cap-at-handle_msg1 entry, which
  describes IK-only behavior that does not apply on next; take master's
  OR-union mesh-size rewrite (next carries the OR-union code); restore
  the Tor connect_refused and MMP receiver-report entries that the
  Fixed-section consolidation would otherwise have dropped.
- lifecycle.rs: keep the mDNS/LAN handshake doc-comment as Noise XX
  (next unifies on XX), not master's XX-to-IK correction.

Quartet green on the merged tree: fmt, build, clippy -D warnings, and
cargo test --lib (1434 passed).

How-To Guides

Task-oriented, step-by-step recipes for operators with a specific goal in mind. Each guide assumes the reader already knows what FIPS is and wants to get a particular thing done — enable a feature, deploy a component, troubleshoot a class of problem.

How-to guides do not teach concepts (that is the role of design/) and do not enumerate options (that is the role of reference/). They take the reader along the shortest correct path from "I want to do X" to "X is done".

Available Guides

Guide Goal
enable-mesh-firewall.md Activate the default-deny nftables baseline on fips0
enable-nostr-discovery.md Turn on Nostr-mediated discovery (3 capabilities — resolve, advertise, open — across 5 scenarios)
deploy-tor-onion.md Run a Tor onion service for inbound FIPS connections
tune-udp-buffers.md Set host sysctls so FIPS UDP sockets don't get clamped
tune-file-descriptors.md Raise RLIMIT_NOFILE so a busy node doesn't exhaust file descriptors (EMFILE) as peer count grows
run-as-unprivileged-user.md Run the daemon under a dedicated unprivileged service account (drops the default-root posture)
deploy-gateway.md Manually deploy fips-gateway on a non-OpenWrt Linux host (LAN-to-mesh outbound + mesh-to-LAN inbound port-forwards). For the OpenWrt path, see the gateway tutorial.
troubleshoot-gateway.md Diagnostic recipes for the gateway, organised by half (outbound, inbound, common)
persistent-identity.md Provision a stable Nostr keypair so the node keeps the same npub across restarts
host-aliases.md Use shortnames (test-us01.fips, my-laptop.fips) instead of full npubs by editing /etc/fips/hosts or setting peer aliases
set-up-bluetooth-peer.md Configure a Bluetooth Low Energy peer link
diagnose-mtu-issues.md Triage MTU-shaped failures and rule out their imposters (bufferbloat, transport saturation)
