The dashboard had no way to log out; only the login page did.
It now shows the user beside the connection, and "log out" where the
page got in by its session: that ends this browser's session (DELETE
/auth/session), other sessions of the user going on, and opens the
login page. Where it got in by what it can't end, the browser's
password or the proxy's, it says so instead (the token answer now
names `login`, how the user proved it). After logging out, a page
still let in by the browser's password says so too.
A list of a user's sessions, to end one by one, is in future-work.md.

Review 3.1, part of finding 12: a signed value's payload bound path,
user, time and prev, but not the swarm. A user with the same name and
key in two swarms could have an envelope replayed from one into the
other, wherever the path holds no envelope yet (prev "").
The payload now names the swarm (`swarm`), and a node takes an envelope
only for its own. /auth/whoami says the swarm, and continuum-signed and
the example in api.md sign it. Wire version 44: nodes before this
refuse such envelopes, and those after refuse the old ones.

Review finding 8, first part: a refreshed token's lifetime came from
the refresh request, and it kept the session's end. So the five-minute
read-all token a dashboard hands to another member's refreshed into a
12-hour one, renewable for seven days.
A token asked to live less (`lifetime`, at login or refresh) now ends
its session with it: nobody refreshes it past its end, its holder
included, and a session begun from it (POST /auth/session) ends then
too.

POST /admin/quarantine/{id}/replay needs write on _continuum, which
never covers user data, and replayed every path of the entry as the
user who asked: every node refused the user data in it. It now
replays only the paths the user may write and keeps the rest in the
entry (left), for one who may; 403 if the user may write none.
Review finding 3 (quarantine replays).

Opening another member's dashboard passes a token reading only, for
five minutes, in the URL's fragment; its login page begins a session
with it. Tokens may be asked for with a shorter lifetime.

A node refusing changes a peer brought tells it which broke a rule; the
peer judges them itself, and if its rules refuse them too, drops them
with all built on them (its document forked without them, a fresh
actor), quarantining its own writes among them. Wire version 42.

With signatures required, a member whose own change broke a rule is
refused as a whole: sent nothing, shown in /peers (refused), in stats
(sync.refusedPeers) and on the dashboard, until a change of its is
taken again or the epoch changes.

The cookie lets in GET, HEAD and the session's own requests; anything
changing something brings the token itself, which no page of another
site or port can make a browser send. The dashboard's writes send it.

GET /login without authentication: log in by password or with a token
(from a login by key). POST/DELETE /auth/session keep the token as an
HttpOnly, SameSite=Strict cookie; the dashboard sends a browser
without a user there and renews the session while open.

cs1.<age file>: a value encrypted with age to its readers' SSH keys,
which no node decrypts. _continuum/access/sealed declares paths whose
values must be sealed, for named readers or anyone; nodes check the
recipients by age's key tags, at the API and on receipt.
Auth plan M8, reworked: sealed values instead of containers, readers
as users only (nodes hold no keys).

POST /auth/challenge and /auth/login/key: a node-signed challenge,
valid five minutes and taken once, signed with one of the user's SSH

PUT with application/continuum-signed writes an envelope where values
are signed (403/409 saying why); reads open envelopes and name the
signer (x-continuum-signed-by), ?raw=true shows them. Under strict,
unsigned writes reaching a signed value and the users API are 409.

_continuum/logouts/<name> holds when a user's tokens were last revoked,
written by the user itself or by one who may manage users, so users'
entries can be signed by their managers alone.

_continuum/access/policy ({"version": 1}) has every node screen every

doesn't know stops its writes through the API. GET /admin/refused.

Every node signs the changes it commits with its node key, an Ed25519
signature over the change's hash, kept beside the document. One
signature on an actor's latest change vouches for its earlier ones.
Protocol data and paths listed in _continuum/access/signed are signed,
and writes with ?signed=true.

The dashboard reads every member's links from the members themselves;
LINKS and LINKS_REPLY, swarm::links and their wire tags go (wire
version bumped). Nodes the browser can't reach are drawn from what the
reachable ones measure.

/admin/users: list, add (one or several), remove, disable, grant and

Every request is judged by the registry the node holds: store reads
pruned to what the user may read, writes refused where it may not,
admin endpoints by protocol capabilities. Without a registry, as
before (--protocol-writers for protocol data).
