Land v0.4.0 pre-release source content: docs, changelog, packaging
Bring the source tree to its finished v0.4.0 content state ahead of the release candidate. Documentation, changelog, release notes, and packaging metadata only; no code or version-string changes. CHANGELOG.md: backfill the operator-visible changes that landed since v0.3.0 (the show_metrics scraper query and fipsctl stats metrics, the discovery dedup-cache-full counter, the off-rx_loop control read surface and its new daemon-resolved fields, the fipstop TUI overhaul, the TCP inbound cap now honoring max_connections, host-map hot-reload, log-noise demotions, and the net bug fixes), topic-grouped rather than replayed per commit; intra-cycle fixes folded into their feature entries; the duplicate Unreleased Fixed section merged into one. Release notes: author docs/releases/release-notes-v0.4.0.md to the operator-upgrade bar and mirror it byte-for-byte into the root RELEASE-NOTES.md. Attribute each feature to its author in Contributors (Nym transport and the mixnet demo to @oleksky, opt-in mDNS LAN discovery to @mmalmi). README.md: add the Nym transport to the support matrix (Linux, macOS, Windows; OpenWrt pending verification), the multi-transport bullet, and the "What works today" list; fold mDNS LAN discovery into the existing Nostr-discovery bullets; refresh the status narrative to v0.4.0 over a global, public test mesh. packaging/common/fips.yaml: add commented Nym transport and mDNS LAN discovery example stanzas with verified field names and defaults. Cargo.toml: add homepage, keywords, and categories crate metadata. docs/reference: update the cli-fips version example to the released form; document the new control-socket output fields and the typed RejectReason families in control-socket.md; sync cli-fipstop.md with the overhauled TUI keybindings. |

docs: refresh tutorials, how-to, design, reference, and examples for v0.4.0
Pre-cut documentation pass for the 0.4.0 release, verified against current source. Corrections: - fipsctl: stale 'show identities'/'show node' -> 'show status' (host-a-service, run-as-unprivileged-user) - mesh address derivation: first 16 bytes of SHA-256(pubkey) with the leading byte set to 0xfd, not a fixed fd97: prefix (reach-mesh-services, ipv6-adapter-walkthrough) - gateway control socket mode 0660 -> 0770 (troubleshoot-gateway) - Tor example: add advertised_port: 8443 so the published port matches the prose (enable-nostr-discovery) - bloom mesh-size estimate rewritten to the OR-union-of-peer-filters algorithm; plus mtu deep-link, gateway pool wording, and a NAT failure-mode line - examples: delete orphaned nostr-rs-relay config, accept inbound to the local 8443 TCP listener, fix fd::/8 -> fd00::/8 typos, dotless wireguard alias Additions: - new Nym mixnet transport section (fips-transport-layer) and the architecture transport list - new LAN/mDNS discovery section (fips-nostr-discovery) - reference docs: Nym transport, LAN discovery, and new control/stats surfaces; drop ble from the connect transport list |

fipstop: add "Listening on fips0" panel to Node tab
Surfaces local services reachable from the mesh, paired with their
current `inet fips` baseline filter classification. Lands to the
right of the existing TUN section in the Traffic block.
A new daemon control query `show_listening_sockets` returns IPv6
listeners bound to either `::` (wildcard) or the node's fd00::/8
address, each classified as Accept / Drop / Unknown / NoFirewall
against the running inbound chain. fipstop renders the result as a
table beside the Traffic counters: Accept rows in default White,
Drop / Unknown in DarkGray, a yellow banner above the table when
`fips-firewall.service` is inactive, and a trailing `*` on
wildcard binds to remind the operator the bind is not
fips0-specific.
Daemon side:
- `src/control/listening.rs` walks `/proc/net/tcp6` and
`/proc/net/udp6` via the procfs crate (LISTEN state for TCP,
wildcard remote for UDP), filters to fips0-reachable binds, and
resolves inodes to PID / comm via `/proc/<pid>/fd`.
- `src/control/firewall_state.rs` shells out to
`nft -j list table inet fips` and walks the inbound chain.
Recognises canonical accepts (`tcp/udp dport N accept`,
`dport { ... } accept`, `dport A-B accept`), the iifname-scoping
line, conntrack and icmpv6 lines (skipped). Any rule with
unrecognised matchers (saddr filters, jumps, daddr filters) or
non-terminal verdicts forces Unknown classification for the
ports it references. Eleven unit tests cover the classification
logic; the listening enumerator carries a /proc-parsing test of
its own.
- `show_listening_sockets` emits
`{fips0_addr, firewall_active, sockets[]}` with per-row
`{proto, local_addr, port, pid, process, filter, wildcard_bind}`.
fipstop side:
- `src/bin/fipstop/ui/dashboard.rs` splits the Traffic block into
a 50/50 horizontal layout; the existing TUN + Forwarded panel
occupies the left half.
- `src/bin/fipstop/ui/listening.rs` renders the right half.
- `main.rs` fetches the new query each tick when the Node tab is
active. Errors are non-fatal: an old daemon without the query
leaves the payload at None and the panel renders "loading...".
`Cargo.toml` gains `procfs = "0.18"` on the Linux target. IPv4
listeners are not enumerated — fips0 is IPv6-only.
Folded in: revert the default-socket lookup from writability-probe
back to existence-based selection. The previous tempfile-probe on
`/run/fips` silently steered fipstop / fipsctl onto an XDG path
the daemon never bound for any user in the `fips` group whose
shell session had not yet picked up the supplementary group (no
re-login after `usermod -aG`). `XDG_RUNTIME_DIR` is set on every
modern systemd-managed user session, so this hit the common case.
The kernel checks actual group membership at `connect(2)`, so a
user who genuinely cannot connect now gets a clear `EACCES`
rather than a silent path mismatch. Drops the now-unused
`is_writable_dir` helper. `XDG_RUNTIME_DIR` existence validation
is preserved.
Documentation:
- `docs/reference/cli-fipstop.md` — Node-tab row updated, new
"Listening on fips0 panel" section.
- `docs/reference/control-socket.md` — `show_listening_sockets`
added to the read-only queries table.
- `docs/how-to/enable-mesh-firewall.md` — new "Verify with
fipstop" section.
- `docs/tutorials/host-a-service.md` — fipstop callouts at
Steps 3, 5, 6 + Troubleshooting bullet + wildcard-bind reminder
under "What you've learned".
- `CHANGELOG.md` — new bullet under `Added / Operator Tooling`,
resolver `Fixed` entry rewritten to describe the
existence-based final shape.

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. |
