Let a device leave a network, and start over
Joining was one command and leaving was nothing at all: a network went into `state.sqlite` on the first `up` and stayed there, so a mistyped secret left a second network beside the working one with no way to remove it but editing the database by hand. `tsunagi network` lists what this device belongs to. `tsunagi network leave <id>` publishes a signed release first — while the agent is running and its sessions are up — and only then deactivates the network and removes it. The order is the whole point: signed state has no expiry, so the tombstone is the only thing that ever frees the address and the name for the others, and after the network is gone there is nothing left here to sign one with. Peers pass it on, so a member that was away hears it from them rather than from an agent that has already left. With no agent running nothing can sign or send, and the command says so instead of quietly succeeding: `--offline` drops the network locally and says plainly that the others keep the old claim. The outcome always distinguishes "published to nobody" from "not published at all", because they leave the network in different states. A network is named by its id, and a unique prefix will do. The name is refused on purpose: two networks can share one — that is exactly the situation this command exists for — and picking between them for the user is how the wrong one gets left. The author's version counter deliberately survives. Rejoining the same network with the same key must continue above the release, or every replica that holds the release would treat the new claim as stale and the returning member would be invisible for good. The protocol key does not survive: rejoining is joining, not resuming, and coming back with a key the network was told to let go claims an identity nobody holds any more. Plugins learn about it through a new `on_network_forgotten`, which is about what outlives a session rather than what a deactivation tears down. A released member also drops out of the roster `status` prints. The tombstone stays in the record set — a replica that never heard of it would otherwise reinstate the old claim — but listing an author that gave everything up as a member made leaving look like a peer that had broken. `tsunagi wipe` is the other half: it empties both directories, so the device identity, every network, every signed record and everything a protocol kept beside them go at once and the next start is a stranger. It refuses while an agent holds the directory, and refuses a directory with no `state.sqlite` in it, so a mistyped `--state-dir` cannot take somebody's documents with it. Without `--yes` it only prints what it would remove and what membership would be lost. It is not a goodbye and says so: leaving the networks first is what frees their addresses. The local control protocol is 8 — the socket carries a `Leave` request now, since only the running agent can publish the release. Exercised end to end against real agents: leaving by prefix released the address to a connected peer, leaving by name was refused, `--offline` was refused until asked for explicitly, wipe was refused while the agent ran, and the directory afterwards had no identity in it.

Bound every wait that could last for ever
Nine orphaned test processes were found still running from the day before, three of them spinning on a core each for twenty hours. The code they ran is several changes old and the mesh test passes twenty times over now, so the wedge itself is gone — but nothing in the way it was waited on was bounded, which is why a wedge lasted a day instead of failing a run. The harness enforced its deadline only between probes. A probe that never returned — one call into a wedged runtime, which is exactly what a status request is — waited for ever inside the deadline it was supposed to obey. The probe is now bounded too, so the same wedge fails the test in thirty seconds. Shutdown claimed to be bounded and was not. The plugins had a grace period; the network runtimes, the accept loop, the plugin request loop and the endpoint close did not, and a peer that stops reading is enough to hold any of them open. Each now gets a grace period and is aborted after it. The overlay packet loop was not stopped at all: it ends when the device reports end of stream, which a live interface never does, so it outlived the interface it was reading. And a plugin's grace period abandoned the future without stopping the task behind it, so the helper is public and `wg-quic` uses it on its own runtime. The local control socket was unbounded in both directions. A wedged agent left `tsunagi status` hanging with nothing on screen and no way out but Ctrl-C; it now says the agent did not answer, after five seconds, and falls back to the state store as it already did for a socket that refuses a connection. On the serving side, a connection that sends no request no longer holds a task open. Tests cover the mechanism — a task that stops on its own is not aborted, one that ignores the grace is cut off and drops what it held — and both sides of the change in behaviour: a probe that never answers fails its deadline, and a silent agent is reported rather than waited out. Also: the binary opts out of rustdoc, since it shares a name with the library and `cargo doc` cannot put both in one directory. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

Make the protocol a crate of its own
tsunagi-wg-quic. The line between a protocol and the system level is now drawn by the compiler: nothing in it can reach into tsunagi beyond what tsunagi makes public, and it carries its own version — which is not the version peers compare. Two things the compiler found the moment the boundary was real. The key store was reaching into the core's `pub(crate)` file-permission helpers; those are a legitimate service of the system level, because a protocol keeping keys on disk has the same obligation the agent does, so they are public now with that said. And the test harness was about to be copied into a second crate, which is how two copies start to drift; it is a `testing` feature of the core instead, which is also what anybody writing a protocol would need. The bridges put up while things were moving are gone: the error conversion between the two levels, and the re-exports of the system level's types from the protocol crate. Imports now say which level they come from, which is the point. One deliberate deviation, stated rather than hidden. The authenticated transport stayed in the core. Moving it would have meant handing a protocol the network's keys so it could prove membership itself, and a plugin that can authenticate on the control plane is a worse trade than a module boundary is worth. So the core proves who is at the other end and the protocol owns what is said over it — the same separation, without the secret crossing.
