get_agent_links was proxying to http://127.0.0.1:{port}/api/state.
Since all agents now bind exclusively to a unix socket (HIVE_WEB_SOCKET
set unconditionally in harness-base.nix), the TCP fetch always fails
silently, returning [] — so the nav-strip icons on every card disappear.
Replace with container_view::build_nav_links(), which reconstructs the
same link list from disk:
- stats.html always (container kind)
- /{name} and /agent-configs/{name} when forge-token is present (forge kind)
- extras from hyperhive-dashboard-links.json (external kind)
The GUI screen link is intentionally omitted — /etc/hyperhive/gui.json
lives inside the agent container and is not host-visible. GUI agents
are rare; the omission is acceptable until a host-visible marker lands.
No new dependencies. reqwest is no longer used in dashboard.rs for
this handler (still used by forge.rs and hivectl.rs).
