Review findings 10 and 12, and 3.1/3.3: what stays as it is, said.
* Any member can log any user out: the user a logout names is its
node's word, and a logout is no deciding path, even under strict.
* Used challenges are remembered in memory: after a restart, one
captured within its five minutes could be taken once more.
* A registry turns strict as it is: whatever it holds then counts,
plain values and envelopes, checked or not. Look it over first.
* A value that isn't an envelope starts its chain anew (prev empty).
* A strict registry whose only manager lost its keys changes no more:
keep two managers, or two keys.
* The handed-over token stays in the address bar and history where the
other dashboard never loads, for its five minutes.

Review finding 12, browsers: the dashboard holds a bearer token in
memory and edits the document, but had no content security policy and
could be framed by any page of the same site (another port on the same
host, anything sharing a domain behind a proxy), acting with its user's
token.
The dashboard and the login page now come with a policy that runs only
their own inline script (by its hash, computed when first served),
loads nothing from elsewhere, and lets no page frame them
(frame-ancestors 'none', X-Frame-Options DENY). Fetches stay open to
any origin, as the members' dashboards are wherever the member list
says.
The browser check (check.js) loads the page from a file, without the
header, so the policy wants one look in a browser.

Review finding 8, second part: opening another member's dashboard
handed it a token reading everything (READ_ALL). A member writes its
own dashboard URL, so a malicious one received a read-everything token
under the operator's identity: /admin/config, /admin/changes,
/admin/log and the rest, on every node the user reaches.
The token handed over now reads the member list only (READ_MEMBERS, as
sent to subscribed nodes), which is enough to draw the map; the user
logs in at the other dashboard to see more. With 1151 it lasts five
minutes and isn't refreshed past them.

messages: off / dots / flash: a message expands at its own speed and
leaves an afterglow fading out in the direction it went.

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.

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.

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.

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.

The page compares the clocks the reports on its map carry: this
node's peers', and those of the nodes it subscribes to; the node no
longer gathers them from LINKS (api/dashboard/clocks.rs goes).

The tree drawn is computed as every node computes its own part of it:
from the member list, and whom it and its neighbours reach, as they
told it; no longer from the links members report over LINKS.

Each tick's messages of a subscribed node, listed in the console with
this node's own, from its own stream.

The page reads a subscribed node's message counts from it too, and
draws them as dots on the map, as this node's own.

Double-click a node to subscribe: the page reads its own links from it
directly with a narrowed token (reading the member list only), drawn
over what this node knows; kept per swarm in the browser.

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).
