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. |

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. |

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.

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> |

Exit nodes: offer one per network, send all traffic through a member
A member can offer itself as an exit node per network (off by default); it is announced over the control channel (ctrl/4) once its iptables masquerade and forward rules are in place, with a warning when kernel forwarding is off. A device picks one member as its exit node via policy routing, with the agent's own uid exempt from the tunnel; if the exit node disappears the rules stay and traffic is dropped, loudly reported. CLI: `network exit-node`, `exit-node`; tray: tile checkbox, warnings and a per-device icon with confirmation. Linux only. Co-Authored-By: Claude <noreply@anthropic.com> |

Added per-network LAN broadcast relay
LAN game discovery previously dropped IPv4 broadcasts at TUN ingress. Carry limited and subnet-directed UDP broadcasts to authenticated, opted-in members of the source network, including destinations reached through mesh relays. Preserve the original IP/UDP bytes and deliver received broadcasts only to the local TUN; never reflood them or expose another pair's plaintext at transit. Build immutable recipient snapshots on address and participation changes. The origin sends one ordinary end-to-end encrypted copy per recipient; the existing fast, bounded-hop transport router remains unchanged. Validate UDP framing, source ownership and destination admission without game-specific port rules. Keep network domains isolated and refuse implicit gateways to physical LANs. The separate broadcast policy/domain layer is the extension point for future authorized subnet exports; physical capture, bridging and LAN deduplication are deliberately not implemented yet. Persist default-on participation independently for each local network. Add join --no-broadcast/--broadcast and network broadcast <id> [on|off], including live updates and authenticated announcements. Joining without a flag preserves the saved choice. Opt-out stops local origination and delivery, while opaque unicast transit for other members keeps working. Migrate SQLite schema 3 to 4 without replacing identities or signed state. Use control ALPN 3 and local IPC protocol 14 for the new announcement/request shapes; update peers and restart running agents together. The data ALPN 4 envelope remains unchanged. No release version bump, tag or push is included. Document agent-owned commits in AGENTS.md: short English subjects, explanatory bodies, scoped staging, honest validation, and repository-local fallback author AB <ab@hexor.cy> only when an effective name/email is missing. Release actions remain the user's responsibility. Validation on Windows: cargo fmt --all -- --check; cargo check --locked --workspace --all-targets; cargo clippy --locked --workspace --all-targets -- -D warnings; release workspace/all-target tests: 313 passed. The two existing SQLite wipe failures (a_wipe_removes_everything_and_the_next_start_is_a_stranger and wiping_twice_is_as_ordinary_as_wiping_once) were explicitly skipped; the public-DHT smoke test and forwarding benchmark remain ignored by default. New coverage exercises real iroh/WireGuard multihop fanout, single delivery, runtime opt-out, unicast replies, domain isolation, malformed input and schema migration. TUNs are in-memory; actual games and OS adapter selection were not tested. |

Implement fast userspace multihop mesh routing
Replace the one-intermediate-peer relay with protocol-scoped connectivity graphs and precomputed shortest-path/ECMP forwarding snapshots. Independent transport readers forward opaque transit frames without a plugin or TUN round trip. Carry source, destination, a bounded hop limit and stable flow tags; preserve end-to-end WireGuard links across topology changes. Classify IP flows before encryption and preserve their tags through the WireGuard pending queue. Add offline four-agent path-change coverage, loop and isolation tests, and an opt-in release forwarding microbenchmark. Bump control/data ALPNs while preserving persistent network identities and state. Also include the pending Windows Mainline idle-timeout fix and its regression test, using a reproducible vendored dependency patch. Validation: fmt, workspace Clippy with warnings denied, and 307 release tests passed. Two pre-existing Windows SQLite wipe failures were excluded; public DHT and the manual benchmark remain ignored by default. The forwarding microbenchmark measured 103 ns (64 B) and 202 ns (1280 B) per transit packet, excluding encryption and socket I/O. |
