Retire offline node claims with equal network-wide cleanup rights
Offline devices reserved names and IPv4 addresses indefinitely, leaving stale members in the device history. Give every authenticated network participant the same right to retire another device's observed signed claim without an owner, quorum, permanent identity ban or secret change. Add a separately signed retirement containing the target's original signed claim as proof. Verify both signatures and network scopes, retain the strongest proved cutoff per target with deterministic ties, and suppress claim versions at or below it in membership, hostname ownership and IPv4 allocation. Keep the old signed records and range agreement, and retain markers after a newer claim returns so old replicas cannot resurrect obsolete reservations. A returning device signs a newer claim, allocates against current holders and resets its previous hostname priority rather than taking a reused name with an old time. Commit local retirement and the requester's author counter atomically before announcing it; receivers persist proofs before applying them. Bound history to 1024 targets by default, reject additional targets without evicting protection, and treat corrupt or over-limit mandatory storage as an explicit error. Repeat bounded marker batches with a per-session rotating cursor so queue pressure cannot indefinitely starve later markers. Exclude retired claims and cached hints from history-derived discovery without preventing a fresh authenticated device from returning. Expose Agent::forget_node through the shared local control API. CLI command tsng network forget-node accepts exact network names, full ids or unique id prefixes, and exact node hostnames, ids, prefixes or overlay IPv4 addresses. Ambiguous selections change nothing. Recheck the observed version and refuse self, online nodes, the selected exit node and absent or changed claims. Add Forget with an identity confirmation to offline tray device rows. Widen Show devices to 1440x640 with an 800x400 minimum to fit its contents. Control ALPN/version advances to tsunagi/ctrl/7 and local IPC to 21; upgrade all peers and restart the agent with matching CLI/tray clients. Data ALPN 5, network identity derivation, handshake encoding and existing record signing bytes remain unchanged. SQLite schema 9 adds retirement storage while retaining identity, secrets, settings and signed claims. Document behavior and limits. Validation on Linux through nix develop: - cargo fmt --all -- --check - cargo clippy --locked --workspace --all-targets -- -D warnings - cargo test --locked --workspace --all-targets: 519 passed, 2 existing ignored tests; inherited TSUNAGI_CONTROL_SOCKET and TSUNAGI_CONTROL_GROUP were unset - git diff --check and the built CLI forget-node help Tests use real iroh authentication and SQLite. Cover restart, stale-replica recovery, equal rights and network isolation, hostname reuse and return, twelve marker batches through a two-message queue, malformed signatures and proofs, invented future cutoffs, deterministic merge, capacity, migration and injected counter-write rollback, selectors and cleanup through two real CLI processes. Earlier iterations caught a private test API, a collapsible tray conditional and a crash-based CLI test waiting for QUIC's idle timeout; corrected before the final successful suite. Manual tray rendering, macOS/Windows, privileged TUNs and public-network traversal were not run. The requested RC tag is v0.1.0-rc.31; no push was requested. |

Change network protocol selections at runtime
Protocol selection previously belonged to tsng up and therefore to the service command line. A blocked or degraded carrier could only be removed by editing the service and restarting the whole agent. Make the ordered selection a local per-network setting instead. Add Agent::set_protocols and a local control request shared by CLI and tray. Keep tsng protocols without arguments as the protocol catalog; naming a network shows its selection and supplying a comma-separated list replaces it. Accept exact names, full ids and unique prefixes using shared selector rules; ambiguous selectors and invalid lists change nothing. An explicit none selects control-only operation. Offline edits take the directory lock and apply on the next start; live edits never write behind the daemon. Register every built-in plugin and transport in the CLI. Treat up --protocol as ordered initial defaults for networks without an override, allowing a protocol absent from the unit to be enabled later. Retain the targeting of unqualified startup options and allow explicitly scoped options to configure initially disabled protocols. Persist NULL for inherited preferences and an empty selection distinctly in SQLite schema 8; migration preserves existing identities, secrets, signed records and counters. Serialize changes with network lifecycle operations and commit preferences before applying or announcing them. Retire only the affected network's data links and E2E channels, cancel pending opens, and reject obsolete completion results by attempt id. Clear peer data channels when authenticated protocol capabilities change while retaining control sessions and topology. Replay allocations and peer identities after asynchronously prepared plugins become ready. A control-only start defers creation of the agent's single interface until data is enabled; plugins receive a sink that can use it later. Automatic carrier fallback continues to preserve E2E state; explicit policy changes renegotiate it. Identity derivation and peer wire formats are unchanged. Add a collapsible protocols row to each tray network tile, with a catalog provided by the daemon, descriptions, immediately applied checkboxes and preference-order buttons. Keep editing disabled until the worker refreshes status so a second click cannot overwrite an edit using a stale snapshot. Local IPC wire version is 20 for the new request and report fields; upgrade and restart agent, CLI and tray together. Crate release versions remain unchanged; the requested RC tag is v0.1.0-rc.30. Validation on Linux through nix develop: - cargo fmt --all -- --check - cargo clippy --locked --workspace --all-targets -- -D warnings - cargo test --locked --workspace --all-targets: 509 passed, 2 existing ignored tests, with inherited TSUNAGI_CONTROL_SOCKET and TSUNAGI_CONTROL_GROUP removed Tests use real iroh membership, SQLite, UDP, AWG and WireGuard encryption, QUIC carriers and memory TUNs. Cover either endpoint-id role, full-size packet delivery after switching, an unaffected second active network, saved selection after restart, empty/invalid selections, first enablement without restart, rapid changes racing old opens, live and offline CLI changes, startup-absent protocols and preservation of signed state through migration. Earlier compile and focused-test iterations caught initializer mistakes, a short test secret, asynchronous plugin allocation readiness, and an inherited system socket path; corrected before the successful final checks. Plain cargo was unavailable in the host shell, so validation used the Nix toolchain. Manual tray interaction, macOS/Windows, privileged host TUNs and public-network traversal were not run. |

Add ephemeral pairwise Amnezia transport and runtime fallback
Plain WG and QUIC can be blocked or severely degraded while the iroh control connection still works. Add an awg carrier with one independent UDP socket, WireGuard engine and randomized masking profile per network/peer attempt. The smaller endpoint id negotiates fresh outer keys, PSK, header protection, header ranges, padding and signature templates through private authenticated control messages. Restart or fallback reentry generates a new profile; ordinary rekeying preserves the current profile. No pair parameters enter signed state, capabilities, persistent storage or public message events. Private payloads and serialized control buffers redact and zeroize themselves. Adapt the bounded packet masking engine from RunaRoo/AmneziaWG-RS at commit 51579a7d6e8882d1d8d6d00822f09e18a9423b73, retaining its Apache license and provenance. Declare WTFPL AND Apache-2.0 in package metadata to cover both new glue and the adapted source. Reuse boringtun instead of upstream's Node/global executors and interface machinery. This is Tsunagi AWG wire version 1, with standard WG headers restored before authentication; external Amnezia server compatibility is not implemented. DNS/SIP signature generators vary fields instead of replaying captures. Each attempt closes independently, bounds allocation, queues, candidates and fragment assemblies, and supports the full 64 KiB carrier contract using UDP packets at most 1200 bytes. Yield between fragment batches so large messages do not starve local socket readers. Keep carrier encryption separate from end-to-end tunnels so multihop relays still forward opaque ciphertext. The system owns the sole interface, signed addresses and admission. Plugins receive neither network secrets nor paths. Expose a bounded opaque control sender at the transport boundary; core control messages remain outside protocol crates. Optional STUN on the pair's actual socket adds IPv4 public candidates in CLI direct/relay mode, with a finite query deadline and an off/alternate-server option. Local mode remains offline. Symmetric NAT, IPv6-only paths and arbitrary UDP blocking can still require fallback; no AWG-over-QUIC or hidden AWG relay is introduced. Default carrier order is wg, awg, wg-quic, tcp-tls. Advance the fallback cycle after setup failures and sustained runtime loss, even after earlier cooldowns expire. Authenticated delivery probes traverse the actual encrypted tunnel, fit the interface MTU and never enter the TUN. Retire after a 20-second warmup and at least 60% loss over at least 15 completed recent observations. Preserve logical tunnels and control sessions while explicitly closing physical links, including TCP reader/writer tasks. Retain the newest private probe settings across independently queued control negotiation and inbound installation. CLI/tray reports keep end-to-end protocol and actual carrier separate. Control ALPN/version becomes tsunagi/ctrl/6 for the new private message; upgrade all members together. Data ALPN/envelopes remain version 5. Network identity derivation, transcript encoding, device identities, signed records, saved network configuration and release versions are unchanged. Validation on Linux through nix develop: - cargo fmt --all -- --check - cargo clippy --locked --workspace --all-targets -- -D warnings - cargo test --locked --workspace --all-targets, with the inherited TSUNAGI_CONTROL_SOCKET override removed: 504 passed, 2 pre-existing ignored Tests use real iroh membership, SQLite, UDP sockets and WireGuard encryption with memory TUNs. Cover three independent pairs, full-size IP and carrier frames, restart freshness/socket release, 80% carrier datagram loss, fallback to real iroh, fresh retries with working delivery checks, unequal small MTUs, malformed negotiations/profiles, role and resource bounds, probe forgery and STUN parsing. Earlier compile/lint iterations and focused tests caught RNG API/initializer mistakes, a retry assertion racing path installation, and a large-fragment burst overflowing loopback buffers; corrected before these successful checks. Normalized upstream license line endings for diff checks. Public NAT/STUN connectivity, actual DPI effectiveness, WAN performance, per-pair memory measurement, macOS/Windows, privileged TUN operations and manual tray interaction were not exercised. |

Derive default network ranges and switch overlapping networks
Every first network previously proposed 10.13.37.0/24. Independently created networks therefore collided when a device joined more than one of them. Use the existing stable NetworkId-derived /24 in 10/8 for every new network, independent of activation order or peer availability. Legacy and explicit signed ranges outrank the derived default; remaining range disagreements still use author-id ordering. The derivation, identity labels, handshake and signed record encoding stay unchanged. There is no creator, timestamp or vote. Reserve ranges before starting network actors and serialise start, stop and switching through the agent lifecycle lock. Refuse equal or nested overlaps without changing a network's subnet locally. A late authenticated range that collides suspends only its network before updating plugins or the interface. Coalesced watch notifications let the agent clean up outside the network actor and reconsider suspended networks when ranges change. An explicit switch stops every blocker before activating the chosen network. Suspended networks retain their startup request and resume whenever their ranges become free, including switching from a wide range to a narrow one. A manual stop cancels that request even for an already suspended network. Persist preference order and enabling together in an SQLite transaction so the user's selection survives restart; no database schema migration is needed. CLI status and network listing show blocker names, ids, ranges and the start command. Network start switches explicitly and reports suspended networks; joining an overlapping network reports it as configured but inactive. The tray adds conflict details, an amber icon, Switch to this network and Keep stopped actions. Local IPC wire version is 19 for the extended reports, so restart the agent and tray together. Release versions and peer wire formats are unchanged. Update the user documentation and compatibility tests. Validation on Linux through nix develop: - cargo fmt --all -- --check - cargo clippy --locked --workspace --all-targets -- -D warnings - cargo test --locked --workspace --all-targets with TSUNAGI_CONTROL_SOCKET removed from the test environment: 486 passed, 2 pre-existing ignored tests - final focused range_conflicts integration suite after making discovery fixtures deterministic: 6 passed Earlier validation attempts caught outdated diagnostic assertions, a new test helper scope error, and the inherited system control socket override. Those were corrected before the successful runs. Plain cargo was unavailable in the host shell, so validation used the Nix development toolchain. macOS, Windows, privileged host TUN operations and manual tray interaction were not exercised. |

Relay across any mix of links, one online answer for every client, first claim owns a hostname
A tunnel no longer depends on the kind of link under it. The relay hub keeps one forwarding table per network instead of one per protocol, the envelope names the end-to-end protocol, and a neighbour reached over several kinds of transport is sent to over the best open one. A member in the middle needs no protocol in common with either end. Which protocol a pair runs is settled by the lower endpoint id's announced order, so both ends agree without asking. A direct link that comes up later is shorter than the path through others, so traffic moves to it with the same logical link. The agent now answers "is it online" once: a live control session or any data path. Members and peers report how they are reached (direct over a named transport, relayed through a named member, or no data path yet), and `tsng status` and the tray both read that instead of a session list and a WireGuard handshake respectively. A hostname belongs to whoever claimed it first. A claim carries the time its author first claimed the name, signed with the record, and replicas order by (time, id) so every member names the same holder. A later claimant keeps working by address, is not found by the name, and is told so in its status, `tsng status`, the tray and a HostnameTaken event. Wire change: control and data ALPN 5, control PROTOCOL_VERSION 5, envelope version 2, signing domain v3, state schema 7, local control protocol 18. Upgrade every member together.

Exit nodes on Windows: use a member as exit node via destination bypass routes
Choosing an exit node on Windows did nothing: the using side was refused, because Windows has no per-user routing and the agent's own traffic would loop into the tunnel it carries. Now the overlay interface gets 0.0.0.0/1 and 128.0.0.0/1 routes (and ::/1, 8000::/1 as an IPv6 blackhole), and every underlay address the agent talks to directly gets a /32 route through the physical default gateway, marked with route metric 7373 so stale ones are found and removed. Bypass routes are written before the halves and removed after them; a failed step removes what was written. All routes are in the active store. The addresses come from the runtime: each network runtime hands the interface the verified direct IPv4 paths of its control connections and the relay hosts in use (Interface::set_underlay, refreshed every dial round); relay names are resolved when the rules are applied. ExitHostRules::needs_bypass (true only on Windows) gates it, so Linux and macOS plans never carry or re-apply on path changes. ExitHostPlan gains `bypass` and `bypass_hosts`; networks leaving forget their entry. Limits: a path that appears after the last apply goes through the tunnel until the next apply; data-plane-only addresses are not collected separately (the data links ride the same iroh paths). Nothing was run on Windows. Checks: cargo fmt --check, cargo clippy --locked --workspace --all-targets -D warnings and cargo test --locked --workspace --all-targets passed on macOS; scripts and ordering are unit-tested with an injected runner and resolver, and Interface::set_underlay with the mock host.

Exit nodes on Windows: offer through WinNAT; using is refused
Windows reported exit nodes as unsupported. The offering side now creates one WinNAT object per offered range (New-NetNat, named tsunagi-exit:<if>:<range>), prunes this interface's stale ones, reads (never writes) IPv4 forwarding of the overlay interface, and removes everything on clear. All values are single-quoted PowerShell literals. The using side is deliberately not implemented: Windows has no per-user or per-process routing, so the agent's own QUIC/relay traffic cannot be kept out of a default route through the overlay and would loop. It reports that reason and installs no route. The CLI/tray forwarding hint and the kernel-forwarding warning name the Windows command; docs/exit-node.md has a Windows section. Checks: cargo fmt --check, cargo clippy --locked --workspace --all-targets -D warnings and cargo test --locked --workspace --all-targets passed on macOS. The script builders and plan logic are unit-tested with an injected runner on every platform; nothing was run against a real Windows host or cross-compiled (no Windows target installed).

Exit nodes on macOS: pf anchor for offering, routes plus route-to for using
The exit-node host rules existed only for Linux (iptables + policy routing); macOS reported "only supported on Linux yet". Offering: a pf anchor com.apple/tsunagi-exit-<if> (evaluated by the stock pf.conf) holds a nat rule per offered range and a pass-in rule. pf is enabled if needed and the pfctl -E reference is released when the rules are removed. net.inet.ip.forwarding is only read, never written, as on Linux. Using: macOS has no uidrange policy routing and the agent is root, so the overlay gets 0.0.0.0/1 and 128.0.0.0/1 routes and a pf route-to rule (matched by the agent's uid) sends the agent's own QUIC/relay traffic back out the physical interface, translated to its address. The rules are loaded before the routes, so a failed load never sends traffic into a tunnel it cannot exempt the agent from. IPv6 is blocked with rejecting ::/1 and 8000::/1 routes. ExitHostPlan gains `overlay` (every network range) for the route-to exemption; Linux ignores it. Known limits: the egress is the default route's interface at apply time; other root processes also bypass the tunnel. Forwarding hints in the CLI and tray name the macOS sysctl. The rule text and command order are unit-tested with a scripted host; nothing was run against a live pf/route (needs root), so the route-to + nat second-pass behaviour is unverified. Checks: cargo fmt --check, cargo clippy --locked --workspace --all-targets -D warnings and cargo test --locked --workspace --all-targets, run on macOS only.

Tray state icon and window picture; firewall rules without the comment match; macOS app bundle
The tray icon is dark red with no connection (or a lost exit node), blue when connected and green while an exit node is in use; the windows get the logo and an app id that matches the desktop entry, and the exit icon moves to the bottom left of the tile. Exit-node and broadcast firewall rules fall back to being recognised by their shape on kernels that have no `comment` match, as small router builds do. The macOS archive carries Tsunagi.app for the Homebrew cask, and the daemon plist opens the control socket to the admin group. Co-Authored-By: Claude <noreply@anthropic.com> |

Rename the CLI package to tsunagi and its executable to tsng
The command line package is now `tsunagi` and builds the `tsng` executable, which the packages, the unit, the installers and the workflows install and run. The core library package becomes `tsunagi-core`, keeping the library name `tsunagi`, so no code changes `use tsunagi::...`. Directories follow (crates/tsunagi-core, crates/tsunagi). Every command shown to a person is now `tsng ...`. Co-Authored-By: Claude <noreply@anthropic.com> |
