feat(openwrt): open !FIPS access SSID layer (#126)
Access layer for phones and laptops to reach FIPS routers on OpenWrt, stacked on the 802.11s mesh backhaul from #123. Squashed from five commits by Arjen (Origami74); their original messages follow. * feat(openwrt): open !FIPS access SSID — fips-ap-setup helper, default transport binding, how-to Client access layer for phones and laptops: every FIPS router broadcasts the same open SSID ('!FIPS' — the leading '!' sorts it to the top of alphabetically ordered network pickers), forming one standard ESS. Clients save it once and roam between all FIPS routers natively, with FIPS's Noise IK handshake as the only security layer: - fips-ap-setup: opt-in UCI helper that creates the 'fips-ap0' open AP (encryption none — security type must be uniform across routers or clients treat the ESS as different saved networks), an isolated network with a static ULA /64, RA-only odhcpd addressing (stateless SLAAC, no DHCP — the minimum that satisfies Android's provisioning check; no internet by design, so phones keep cellular as default route), and a locked-down fips_ap firewall zone (no path to br-lan or the WAN; only ICMPv6, mDNS, and the FIPS transports reachable). 'remove' subcommand undoes it. Radio setup stays opt-in; a package must not commandeer radios on install. - fips.yaml: ship 'ap0'/'ap1' Ethernet-transport entries commented out (matching the 802.11s mesh backhaul) so a stock install that never creates fips-ap* logs no per-boot "interface missing" bind warning; fips-ap-setup uncomments the matching block when it creates the interface and re-comments it on remove. - Regression test: extend shipped_openwrt_config_parses to assert the ap0/ap1 entries ship commented out and still parse once uncommented, alongside mesh0/mesh1. - Packaging: install the helper in ipk/apk/buildroot (three synced copies), extend CI structural checks and shellcheck targets. - docs/how-to/set-up-open-access-ssid.md: full guide, including the one-time 'no internet, stay connected' acceptance (stored per SSID, covers every FIPS router) and the security-type-uniformity constraint. * docs(openwrt): correct open-SSID/mesh security framing — peering is open by design The fips-ap-setup/fips-mesh-setup comments and both how-tos claimed a stranger "cannot pass the FIPS handshake" / "their frames die at the handshake" / the handshake surface "drops them". That is wrong: FIPS peer admission is open. An inbound handshake from any net-new identity is promoted (node::handlers::handshake::promote_connection), gated only by the daemon's max-peers cap — there is no allowlist, no PSK, and the AuthChallenge path is not wired to admission. The Noise IK handshake provides authentication (no impersonation of another identity, no MITM), not authorization. Restate the model accurately in all five places: a stranger on the open SSID (or the open mesh) can associate AND form a FIPS peer link — that is the point of open access. Containment is the isolated fips_ap zone (no path to br-lan or the WAN) plus the max-peers cap, not the handshake. Clarify that AP client isolation is an L2 control only: a peered stranger is an overlay peer like any other, so the FIPS overlay, not L2, is the trust boundary between clients. * feat(openwrt): serve DHCPv4 on the access SSID from a fixed roamable subnet RA-only addressing satisfied Android's provisioning check but left anything expecting IPv4 with a self-assigned address and a "no IP" complaint. dnsmasq now leases out of 10.21.<N>.0/24 (N = radio index; prefix echoes FIPS port 2121), deliberately identical on every router: a roaming client keeps its lease across the ESS, and dnsmasq's authoritative mode — the OpenWrt default, pinned by the helper — ACKs the renew a foreign router never issued. Lease collisions across routers surface as a NAK on renew and the client re-DHCPs. The dhcp section's 'dhcpv4 server' is read by both dnsmasq (default images) and odhcpd (only with maindhcp), so either arrangement serves. A DHCPv4/udp-67 accept rule joins the fips_ap zone; DHCPv6 stays off, the ULA RA stays as-is, and nothing depends on an upstream. The zone remains isolated — no forwardings, no internet. * feat(openwrt): enable mDNS rendezvous from fips-ap-setup Phone FIPS apps cannot open raw-Ethernet sockets, so DNS-SD is how they find the router's daemon — but node.rendezvous.lan defaults to off. Ship the lan block commented in fips.yaml (consistent with the apN transport entries) and have fips-ap-setup uncomment it when creating the access SSID. The awk match is scoped to node.rendezvous because transports.ethernet carries a 'lan' entry at the same indent. The switch is daemon-wide, so 'remove' deliberately leaves it on rather than guess whether other transports rely on it. * fix(openwrt): bind UDP dual-stack [::]:2121 so access-SSID clients reach it The shipped router config bound the UDP transport "0.0.0.0:2121" (IPv4 wildcard) while the mDNS LAN advert announces every interface address, including the router's IPv6 link-local — which phones on the !FIPS access SSID rightly prefer (their cellular default route swallows v4, and fd00::/8 is captured by the Myco mesh TUN). Result: the client's Noise msg1 arrives on an unbound v6 port and is silently lost; the handshake resends and times out. Symptom chain (observed on-device): mDNS resolve OK, platform push OK, "Sent Noise handshake message 1" to [fe80::…%N]:2121, four resends, no reply, 30 s stale-timeout. OpenWrt is Linux (bindv6only=0), so "[::]" accepts IPv4 via v4-mapped addresses too — nothing is lost. packaging/common is deliberately left on "0.0.0.0" for now: Windows defaults IPV6_V6ONLY=1, where "[::]" would drop v4 instead. |

feat(openwrt): 802.11s open-mesh backhaul support
Router-to-router radio backhaul over an open 802.11s mesh interface, with FIPS providing all encryption (Noise IK), authentication, and routing on top of bare L2 neighbor links. The mesh runs OPEN with mesh_fwding 0 — SAE would duplicate the Noise layer and force ath10k raw mode, and FIPS is the routing layer — so the Noise handshake is the real auth/encryption boundary and FIPS's spanning tree does the routing. fips-mesh-setup: an opt-in UCI helper that creates a per-radio mesh-point interface (radio0 -> fips-mesh0, radio1 -> fips-mesh1; trailing-digit derivation with a free-index fallback and a collision guard). Radio setup stays opt-in — a package must not commandeer radios on install. 'remove' takes an optional radio and otherwise removes all instances. Dual-band routers get one instance per radio; FIPS treats the two backhaul paths as failover, not multipath: it keeps one active link per peer (cross-connection resolution picks a single winner), and the second band stands by, re-establishing the peer after keepalive timeout — traffic never uses both bands at once. fips.yaml ships the mesh0/mesh1 Ethernet-transport entries commented out, so a stock install that never creates fips-mesh* logs no per-boot "interface missing" bind warning. fips-mesh-setup uncomments the matching meshN block when it creates the interface and re-comments it on remove, so the flash-and-drop-in flow needs no manual config edit. The file is rewritten 0600-first (it may hold an inline nsec) via an atomic replace. Two field-found silent non-peering causes are surfaced by the helper and the guide: - Same channel: mesh points only peer on a shared channel, and 'auto' lets each radio pick its own. The helper prints the radio's band/channel and warns loudly on 'auto' with the exact uci command to pin one; the how-to gains an ordered no-peers triage (channel mismatch, on-air scan check, DFS CAC wait, regdomain). - STA channel capture: a client (sta) interface drags the whole radio to its upstream AP's channel, so a mesh pinned elsewhere never joins and does not recover until the STA disconnects. The helper warns when the target radio carries a STA; the guide documents the incompatibility of a roaming uplink with a fixed-channel mesh on the same radio. Both the create and remove paths run 'wifi reload', which briefly drops every client AP on all radios; the how-to sets that expectation. Regression test: the shipped OpenWrt fips.yaml must parse via the real Config deserializer in both states — as shipped (mesh inactive) and after the uncomment the helper performs. Packaging: the helper is installed across the ipk/apk/buildroot paths (three synced copies), with the CI structural checks and shellcheck targets extended to cover it. Full guide in docs/how-to/set-up-80211s-mesh-backhaul.md. |

transport/ethernet: rename config discovery flag to listen
Rename the Ethernet per-interface config flag from discovery to listen, so the receive/transmit toggle pair reads as the symmetric announce (transmit) / listen (receive) neighbor-beacon vocabulary. The old discovery: key is still accepted via a serde alias, so deployed configs load unchanged; to_yaml re-emits it under the canonical listen: name. Marked deprecated for removal at the v2 cutover. Updates the config field + accessor, the transport listen_enabled local, the one struct-literal test consumer, the chaos sim config generator, packaged fips.yaml examples, and the classified operator-facing docs (ethernet neighbor-beacon subsystem prose; the generic Transport discovery capability prose is left unchanged). Adds a compat parse test asserting the legacy alias, the new key, and that deny_unknown_fields still rejects unknown keys. Behavior-neutral. |

Disambiguate the mesh-lookup "discovery" name across the source tree
The identifier "discovery" named three unrelated subsystems; the FMP overlay coordinate-lookup subsystem is now consistently "lookup". This finishes the concept-#1 rename across the shell, config, and metric layers left after the earlier proto-layer rename: - Handler module node::handlers::discovery -> node::handlers::lookup, and reset_discovery_backoff -> reset_lookup_backoff. - The Node lookup-engine field Node.discovery -> Node.lookup, renamed by resolved binding so the metrics().discovery and node.discovery config paths are left untouched. - The lookup metric types DiscoveryMetrics -> LookupMetrics, DiscoveryStatsSnapshot -> LookupStatsSnapshot, and Metrics.discovery -> Metrics.lookup. Two surfaces cross a stability boundary and ship behind a compatibility window, both marked in-code for removal at the v2 cutover: - The control-socket metric family is dual-emitted under both "discovery" (deprecated alias) and "lookup" so existing dashboards keep working. - The node.discovery.* config table is split into node.lookup.* (mesh lookup scalars) and node.rendezvous.* (nostr/lan peer rendezvous). NodeConfig does not deny unknown fields, so a naive rename would make a deployed node.discovery: block deserialize into nothing and silently revert every setting to default. A deprecated all-Option DiscoveryConfigCompat field captures a legacy block and a new post-parse Config::normalize_deprecated_keys pass folds it into the new tables with a one-time deprecation warning. Flip the packaged fips.yaml templates to the new keys, add legacy/new/ scalar compat parse tests, and record the split and deprecations in the CHANGELOG. Behavior-neutral; fmt/clippy clean, lib suite green. |

packaging(openwrt): SDK-free .apk build for OpenWrt 25+ and control-socket fix
Add OpenWrt .apk packaging for OpenWrt 25+, where apk-tools is the mandatory package manager. The existing .ipk continues to cover OpenWrt 24.x and earlier. Built SDK-free like the .ipk: it reuses the cargo-zigbuild cross-compile and the shared installed-filesystem payload under openwrt-ipk/files, and assembles the ADB container with the official `apk mkpkg` applet from apk-tools 3.0.5 built from source, so no OpenWrt SDK image is needed. The package-openwrt workflow is refactored so a single compile-binaries job cross-compiles and strips each arch once; both the .ipk and .apk packagers consume the binaries via a new --bin-dir flag instead of each recompiling. A build-apk job (aarch64, x86_64) builds apk-tools, packages, and structurally verifies the .apk with `apk adbdump`. Releases now publish .apk artifacts and checksums alongside .ipk; the release download is scoped to fips_* so the shared raw-binary artifacts are not swept into the published release. apk-version.sh maps a release tag or commit height to an apk-tools-valid version, covered by a case-table test. Packages are unsigned, installed with `apk add --allow-untrusted`, matching the .ipk posture. Also fix the OpenWrt control socket: the init script now pre-creates /run/fips before starting the daemon, the procd equivalent of the systemd unit's RuntimeDirectory=fips. Without it, on a fresh boot the daemon resolves its control socket to /tmp (since /run/fips does not yet exist), while fips-gateway later creates /run/fips for its own gateway.sock, leaving fipsctl/fipstop resolving a /run/fips/control.sock the daemon never bound. |

chore: replace real IPs in docs and configs with placeholders
Operator-facing IPs in user-visible configs/docs (examples, tutorials, packaging, sidecar templates) are now the resolvable hostnames of the public test fleet (test-us01.fips.network, etc.) so they keep working without baking specific addresses into examples. Doc-comment and test fixtures in src/config/transport.rs use RFC 5737 TEST-NET-2 (198.51.100.1) so they cannot accidentally point at a real host. Also resyncs the openwrt-ipk fips.yaml with the common reference (merge from master) and applies the same DNS-name swap there. |

openwrt: resync /etc/fips/fips.yaml with common reference
Bring the OpenWrt-shipped fips.yaml back into line with
packaging/common/fips.yaml, which had drifted: the OpenWrt copy was
missing the Nostr discovery, BLE, and TCP reference comment blocks, so
operators had no in-config hint that Nostr-mediated discovery existed.
Take common/fips.yaml verbatim and apply just the OpenWrt-specific
active overrides:
- ethernet: uncomment with wan/wwan/lan defaults (eth0, phy0-sta0,
br-lan)
- gateway: uncomment with lan_interface=br-lan and dns.listen on
[::1]:5353 (matches the dnsmasq forwarder the init script wires up)
Identity stays ephemeral by default (no persistent override), matching
common.

gateway: change dns.listen default to [::1]:5353
The gateway is designed for systems already serving DHCP and DNS to a LAN segment (canonically an OpenWrt AP). On those systems port 53 is already taken by the existing resolver, so the prior `[::]:53` default conflicted with the gateway's intended deployment target out of the box. The OpenWrt ipk previously overrode this in its packaged config as a workaround; matching the source default to what the canonical deployment actually wants makes the override redundant and removes a foot-gun for fresh manual Linux-host installs. The redundant `dns.listen` line in `packaging/openwrt-ipk/files/etc/fips/fips.yaml` is dropped along with this change. Operators on a host without a pre-existing resolver on port 53 can opt back into the wildcard bind by setting `dns.listen: "[::]:53"` explicitly. The new default binds IPv6 loopback only — Linux IPv6 sockets bound to explicit `::1` do not accept v4-mapped traffic, so forwarders that reach the gateway over IPv4 loopback need to be pointed at an explicit IPv4 listen address instead. Touches the gateway config struct and its default-value test, the commented-out gateway example in the Debian common fips.yaml, the OpenWrt ipk config (override removed), the gateway reference / how-to / design / tutorial / troubleshoot docs, and a CHANGELOG entry under [Unreleased] -> Changed. |

docs: four-section /docs/ restructure with new-user content, accuracy pass, and gateway feature-set rewrite
Restructures /docs/ by reader purpose (tutorials, how-to, reference, design), adds the new-user-progression and operator-recipe content the prior layout lacked, runs an accuracy pass against current source across the pre-existing design docs, and rewrites the gateway feature-set documentation end-to-end around its actual operational profile (a niche feature designed for systems already serving DHCP/DNS to a LAN, with two independent halves — outbound LAN→mesh, inbound mesh→LAN — sharing one nftables table, one binary, and one control socket). Top-level README and getting-started rewritten around two equally-weighted deployment modes (overlay on existing IP networks; ground-up over non-IP transports). ## Additions - 11 new tutorials in docs/tutorials/: an 8-step new-user progression from single-daemon test-mesh peering through to a ground-up two-device mesh, an IPv6-adapter side-trip walkthrough, an Advanced Tutorials index, and a hand-held OpenWrt walk-through for fips-gateway deployment that exercises both halves of the feature. - 12 new how-tos in docs/how-to/: firewall activation, Nostr discovery (resolve / advertise / open across five scenarios), Tor onion (directory + control_port modes), UDP buffer tuning, unprivileged-user setup, persistent identity, host aliases, Bluetooth LE peering, MTU diagnostics, manual Linux-host gateway deployment (covers both halves), gateway troubleshooting (organised by half), and a section index. - 9 new reference docs in docs/reference/: configuration, wire formats, control-socket protocol, four CLI references (fips, fipsctl, fipstop, fips-gateway), security posture matrix, and Nostr events catalog. Configuration and wire-formats are renamed-and-extended from prior design/ versions; the other seven are net-new. - 6 new design docs: fips-concepts, fips-architecture, and fips-prior-work split out of the deleted fips-intro.md; consolidated fips-mmp and fips-mtu aggregations; and a new generic port-advertisement-and-nat-traversal doc (Nostr-signaled port advertisement plus UDP NAT-traversal protocol, FIPS as an example implementation, suitable for eventual NIP submission). - Top-level docs/getting-started.md walking through the binary-installer-only Install story. - packaging/common/hosts pre-populated with the eight public test-mesh nodes so shortnames resolve out of the box on every fresh install. ## Changes - 23 wire-format diagrams relocated to reference/diagrams/ alongside the wire-formats move. - 4 design diagrams corrected against source code (fips-protocol-stack, fips-identity-derivation, fips-coordinate-discovery, fips-routing-decision). - 10 pre-existing design docs reconciled with current source. Numeric corrections: stale link-MMP report bounds (now [1s, 5s] with 200 ms cold-start floor); UDP default MTU (now 1280, IPv6 minimum); node_addr formula (SHA-256(pubkey)[..16]); Noise patterns (IK at link, XK at session); peer-ACL semantics (strict allowlist requires ALL in peers.deny); daemon DNS upstream ([::1]:5354); on-the-wire bloom-filter size (1,071 bytes); obsolete Cargo-feature references (PR #79 dropped them) removed. - Transport framing tightened across the docs: TCP is for UDP-filtered networks (not NAT traversal); Tor is a deployment mode (not failover); WebSocket dropped (not a shipped FIPS transport); WiFi promoted to Implemented via Ethernet in infrastructure mode; classic-Bluetooth row removed (BLE is the only Bluetooth-mode transport). - docs/design/fips-gateway.md rewritten end-to-end to lead with the niche-feature framing and the two-halves structure. Title moved from "FIPS Outbound LAN Gateway" to "FIPS Gateway"; architecture section describes the common machinery (the fips-gateway service, the nftables table, the control socket) before splitting into separate "Outbound Half" and "Inbound Half" sections of equal weight; security considerations split per-half; no Future Work section (speculative directions live in the project tracker, not in protocol design docs). Inbound port forwarding is a first-class half rather than a buried "Implemented Extensions" subsection. - Gateway terminology unified across all gateway docs as a separate Linux service running alongside the fips daemon (its own systemd unit / OpenWrt init script). Container- pattern terms (sidecar) are reserved for the Docker/Kubernetes sidecar deployment examples — the testing/sidecar/ tree, examples/k8s-sidecar/, examples/sidecar-nostr-relay/, examples/wireguard-sidecar-macos/, and the related CHANGELOG / top-level README entries — where the term carries its standard container meaning. - Net-new design body content: rekey section in fips-mesh-layer (Noise IK msg1/msg2 over the established link, K-bit cutover, drain window, smaller-NodeAddr-wins tie-breaker on dual-init); Mesh Size Estimation and Antipoison FPR Cap sections in fips-bloom-filters; Mesh-Interface Query Filter subsection in fips-ipv6-adapter; failure-suppression knobs and clock- skew tolerance in fips-nostr-discovery; loop-rejection and mid-chain ancestor swap added to spanning-tree propagation / stability rules; Priority Chain in fips-mesh-operation renumbered to match the routing-decision diagram. - Top-level README: dropped the stale nostr-discovery cargo-feature parenthetical. docs/README.md and the four section READMEs (tutorials, how-to, reference, design) refreshed for the new structure; index rows reflect both halves of the gateway feature and the new fips-gateway CLI reference. - Cargo.toml [package.metadata.deb] assets path updated for the fips-security.md move; .gitignore /reference/ rule anchored to repo root so docs/reference/ is trackable. - packaging/openwrt-ipk/files/etc/fips/fips.yaml configuration-doc URL updated to the new docs/reference/configuration.md location. ## Deletions - docs/design/fips-intro.md (split into the three new intro design docs). - docs/design/document-relationships.svg (orphan, no longer referenced). - docs/proposals/ tree removed; the only proposal it contained (the Nostr UDP hole-punch protocol) was rewritten as the new generic design/port-advertisement-and-nat-traversal.md. |

Fix DNS responder silent-drop on systemd-resolved deployments
The previous default configured systemd-resolved with `resolvectl dns fips0 [<fips0_addr>]:5354`, intended to bypass an Ubuntu 22 systemd 249 interface-scoping bug. That target collides with the daemon's mesh-interface filter on Linux: when an IPv6 packet's destination belongs to a non-loopback interface, the kernel attributes the packet to that interface in IPV6_PKTINFO (ipi6_ifindex == fips0) even though loopback delivery is used (tcpdump shows lo). The mesh-interface filter sees arrival_ifindex == mesh_ifindex and silently drops every query at trace level — invisible to operators at the default debug level. Net effect on stock deployments: every .fips query on systemd-resolved hosts was silently dropped. Daemon side ----------- - Default `dns.bind_addr` changes from "::" to "::1" (IPv6 loopback only). The mesh-interface filter is then defanged on the default path because loopback isn't reachable from mesh peers. The filter remains in place defensively for operators who explicitly bind "::" to expose a mesh-reachable responder. fips-dns-setup backend unification ---------------------------------- - New `try_global_drop_in` backend writes /etc/systemd/resolved.conf.d/fips.conf with DNS=[::1]:5354 and Domains=~fips. Inserted ahead of `try_resolvectl` in the dispatch chain. The standard loopback path has no interface scoping, so ipi6_ifindex reports lo and the filter passes. - All other backends now target [::1]:5354 to match the daemon's default IPv6-loopback bind: - try_dns_delegate writes DNS=[::1]:5354 - try_dnsmasq writes server=/fips/::1#5354 - try_nm_dnsmasq writes server=/fips/::1#5354 - Fixed dns-delegate file path: was /etc/systemd/dns-delegate/, must be /etc/systemd/dns-delegate.d/ (with .d suffix). systemd-resolved silently ignored the previous path. - fips-dns-teardown handles the new global-drop-in backend in cleanup. - The legacy resolvectl per-link backend stays as a fallback, documented to require careful daemon bind_addr coordination. fips-gateway upstream pairing ----------------------------- - gateway.dns.upstream default changes from 127.0.0.1:5354 to [::1]:5354 to match the daemon's default bind. Linux IPv6 sockets bound to explicit ::1 do not accept v4-mapped traffic, so the old default would have caused the gateway's startup DNS reachability probe to time out and systemd to restart-loop the service. - Operators who set a non-default daemon `dns.bind_addr` must also set `gateway.dns.upstream` to match — documented inline. Documentation ------------- - packaging/common/fips.yaml and packaging/openwrt-ipk fips.yaml examples updated; rationale for the bind_addr choice and the daemon/gateway pairing recorded inline. Test coverage ------------- - testing/dns-resolver/test.sh: real-fipsd end-to-end scenario added. Builds fipsd in a Debian 12 builder image (cached), runs the daemon with a real TUN in a privileged container, configures DNS via the setup script, and asserts `dig @127.0.0.53 AAAA <npub>.fips` returns AAAA. Refactored as a parameterized helper running across Debian 12/13 and Ubuntu 22/24/26 (5 e2e scenarios). Backend-aware assertions: on systemd >= 258 the expected backend is dns-delegate; on older systemd it's global-drop-in. Strict content checks fail CI on any [::1]:5354 drift. fips-gateway also exercised in the debian12 scenario to lock the gateway-upstream pairing. Renamed all "fipsd" references to "fips" (project convention). - testing/deb-install/ (new harness): builds the actual .deb via cargo-deb in a Debian 12 builder image (cached), installs via apt across each target distro, verifies maintainer scripts, conffile placement, binary placement, and end-to-end .fips resolution after start. Also exercises fips-gateway against the installed daemon to verify the gateway/daemon default pairing on a real .deb path. - This is the test layer that was missing — the previous harness only verified config files were written, never that queries reached the daemon. Verified: dns-resolver 78/78 assertions, deb-install 55/55 assertions across all 5 distros (debian:12, debian:trixie, ubuntu:22.04, ubuntu:24.04, ubuntu:26.04). |

Fix DNS resolution on Ubuntu 22 with systemd-resolved (#77)
On Ubuntu 22 (systemd 249), systemd-resolved applies interface-scoped routing to per-link DNS servers. Configuring `resolvectl dns fips0 127.0.0.1:5354` caused resolved to attempt reaching 127.0.0.1 through fips0 (a TUN with only fd00::/8 routes), silently failing. The DNS responder never received queries. Newer systemd versions (250+) have explicit handling for loopback servers on non-loopback interfaces. Changes: - DNS responder default bind_addr changed from "127.0.0.1" to "::" so it listens on all interfaces, including fips0. Bind logic in lifecycle.rs now parses bind_addr as IpAddr and constructs a SocketAddr, handling IPv6 literal formatting. Factored into Node::bind_dns_socket with explicit IPV6_V6ONLY=0 via socket2, so IPv4 clients on 127.0.0.1:5354 still reach the responder regardless of the kernel's net.ipv6.bindv6only sysctl. - fips-dns-setup resolvectl backend now waits for fips0 to have a global IPv6 address, then configures resolved with [<fips0-addr>]:5354. That address is locally delivered by the kernel regardless of which interface resolved tries to route through. The dnsmasq and NetworkManager backends still use 127.0.0.1 (they don't have the interface-scoping issue). - Dropped hardcoded `bind_addr: "127.0.0.1"` from the packaged fips.yaml (Debian + OpenWrt). The shipped config was overriding the new default. - DNS queries are only accepted from the localhost. Verified end-to-end in a privileged Ubuntu 22.04 systemd container: dig @127.0.0.53 AAAA <npub>.fips resolves cleanly through systemd-resolved. The dns-delegate backend (systemd 258+) still uses 127.0.0.1; it has not been verified whether that backend has the same routing issue. |

Add gateway packaging: CI, systemd, Debian, AUR, OpenWrt
Add fips-gateway binary to CI artifact and Docker build. Systemd service unit with After=fips.service dependency and security hardening. Debian and AUR package entries. OpenWrt packaging: procd init script managing dnsmasq forwarding, proxy NDP, RA route advertisements for the virtual IP pool, and a global IPv6 prefix on br-lan to work around Android suppressing AAAA queries on ULA-only networks. Sysctl config for IPv6 forwarding. Gateway enabled by default in OpenWrt config. Ethernet transport enabled by default. Default gateway config section (commented out) in common fips.yaml. |

Add node.log_level config, remove RUST_LOG from service files
Add log_level field to NodeConfig (case-insensitive, default: info). The daemon now loads config before initializing tracing so the configured level takes effect. RUST_LOG env var still overrides if set. Remove hardcoded Environment=RUST_LOG=info from systemd units and OpenWrt procd init script — these prevented config-driven log levels from working. |
