Put every network's address on the interface, and split up from join
Two networks on one agent, and only one of them worked. The interface plan is exhaustive by contract — it is what the interface should carry and nothing else — but the request that built it held a single address, so the provisioner was told about the first network and took the second one's address off, or never put it on. On the host that is a network whose address the operating system has never heard of: the tunnel is up, the status says all is well, and nothing routes. The request now carries every address, which is also what takes one off when a network is left or stopped. The other half is the command line. `up --network X --secret Y` and `network join` were two ways to do the same thing, and the one on `up` could only be undone by restarting — which is how a network somebody left came back, and how an invite line told the other side to start their agent with a network baked into it. So they are one thing now, split the way the system is: **`up` runs the agent** — the device's one process, serving whatever it has joined, answering `status`, taking instructions — and **`join` decides what it belongs to**, at any time, while it runs. `join` is at the top level because it is what gets typed; `network join` is the same command for anyone who likes the long form. Every line that told somebody to type the old form is gone with it: the invite after making a network, the lock error from a second `up`, the empty-network hint in `id`, the README walkthrough and the WireGuard document. The invite now prints the `join` line for the other machine and, separately, the `up --peer` line for an agent that is not running yet — two commands, because they really are two, and no amount of wording makes starting an agent the same thing as joining a network. Joining says how the network stood before: new, already here, or stopped and now running again. That last one matters — joining is an instruction to run it, so it undoes a stop, and a pause that ends without a word is a pause nobody can rely on.

Serve a zone per network, and make a network in one command
Twice now a report has read "dns not serving" and been taken for a broken resolver. It was accurate both times: the agent had been started without `--dns`. That is the flag's fault, not the reader's — a resolver that disappears because one word was not retyped is worse than none, since the names simply stop working. So the setting belongs to the device now: `--dns` turns it on and it stays on, `tsunagi dns off` turns it off, and `tsunagi dns on` turns it on for an agent that is already running, without restarting it. `tsunagi dns` says what it is doing, or what it will do at the next start when nothing is running. One agent has one identity and as many networks as it likes, so one DNS service serves them all: each network is a zone named after it, and joining or leaving one changes what resolves with no restart. A question carries a name and not the network it belongs to, so the suffix decides and nothing is shared between zones — a member of one network is not a name in another. `--dns-zone` is gone with that: there is no single zone to name any more, and a network name may contain dots, so `--network lab.internal` is how you get `music.lab.internal`. It listens on loopback only, where it always could have. Binding the overlay address put the zones in front of the whole mesh, and with several networks on one agent that would have answered one network's questions about another's names. That made a gap plain: a second network on an agent had no addresses at all, because the configured range belongs to whichever network took it first, so its members had nothing to allocate from and no names to answer with. A second network now uses the range **derived from its own network id** — every member derives the same one from something they all already have, so it is an agreement rather than a local invention. It is held back for a moment first, because a network that already exists has a range of its own and a joiner should adopt it rather than argue; that wait is what keeps "the first member settles it" true. And a network needs no ceremony to start. `tsunagi up --network lab` with no secret resolves the obvious way: the one network of that name this device already has, or — when there is none — a fresh random secret, printed in full with the single line to send the others. That is the ad-hoc case, one person makes a network and passes the command round, and it was previously two steps with a flag people could not find. The secret is printed only when the agent invented it, because then there is nowhere else to read it from; one that was supplied is not echoed. Two networks of one name and no secret is the one case with no answer, and it says so rather than choosing. Releasing now also stops this agent claiming again. The periodic check would otherwise publish a fresh claim in the moment between the goodbye and the teardown, turning a release into a hello nobody asked for. Exercised with the real binary: a zone per network as a second one is joined into a running agent, the resolver switched on and off while it runs, and an ad-hoc network printing its secret and the line to share.

Split the command line by level
`up` now says which level each setting belongs to, and `--help` shows the two sections. System: how the agent reaches peers, the one interface it owns, the address range, the resolver. Transport: which protocols carry packets and what they take. `--wireguard` is gone. `--protocol` takes a list and defaults to `wg-quic`, which is what the protocol is now called — WireGuard's cryptography in QUIC datagrams, so the name says what is on the wire rather than what the implementation borrows. `--protocol none` runs the control plane alone. Protocol settings moved to `-o key=value`, or `-o protocol:key=value` when several are selected. Each protocol declares its own settings and their help, so `tsunagi protocols` can list them without the agent knowing anything about any protocol, and a setting nobody takes is refused rather than dropped — a dropped setting looks exactly like one that did not work. What the user asked for is checked before anything that could fail on its own, so a misspelled protocol is not buried under a privilege error. `--wg-prefix` and `--wg-mtu` became `--interface` and `--mtu`: they were never the protocol's, and the interface they describe belongs to the agent. `--transport` became `--reach`, because "transport" now means the protocol level and using the word for iroh's path policy as well would be a collision of meaning rather than a shortage of words. The plugin gave up the last things that were not its own: the interface name it carried in its own state, and the check that this agent's address is really on an interface. Both are the agent's, and the check is now the agent's too, still said once per address rather than every round. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

Split the system level and the command line into a workspace
First step of separating the layers. The library and the binary are now crates/tsunagi and crates/tsunagi-cli, which means the plugin crate to come can be told apart from the core by the compiler rather than by discipline. Falls out of it immediately: the CLI's dependencies stop being features of the library. clap, anstream and tracing-subscriber were optional dependencies behind a `cli` feature that every library user had to remember to turn off; now they belong to the crate that uses them, and the library defaults to no features at all. The one test that drives the binary moved beside it — a library cannot depend on a binary built from a crate that depends on the library — and was rewritten against the public API instead of the test harness. AGENTS.md said to prefer one crate. It now says the system level and its plugins are separate crates, for the reason above, and that everything else stays one crate.
