#5033 "Share links open only their own dashboard; every route without a
role is on an explicit allow-list". Any live share token in ?s= made the
caller a viewer on every viewer route — host pages, container logs, any
dashboard — and the host-agent widget routes had no role check at all.
- steward/dashboard/share.py: a share token opens, read-only, exactly the
widget fragment URLs its own dashboard loads — same path, same
configured parameters; only the time window (hours/range) may change.
- require_role marks its view; public_route marks the deliberately open
ones (login, setup, health, the share page, agent ingest, install.sh,
agent.py) with the reason. A before_request refuses any view with
neither, so a route that forgets its decorator is closed, not open.
- /plugins/host_agent/widget and /widget/history now require viewer.
- The history widget's range buttons keep the rest of the query (and so
a share link's token) instead of rebuilding it; the uptime widget's
"Full SLA" link shows to logged-in users, not to share viewers.
- tests/test_route_access.py: a source scan that fails on any unmarked
route in core or bundled plugins, the default-deny refusal, and the
share matcher's cases.
