zbus 4.4 does not expose a glib feature; my earlier draft was wrong about
that. Switch the plan to use the workspace tokio config and install a
multi-thread tokio runtime in main.rs, with the runtime guard kept alive for
the lifetime of app.run(). glib::MainContext::spawn_local still drives the
widget-touching closures; tokio's reactor wakes them.
Also: hoist futures-util into the Task 1 dep bundle so Task 6 doesn't need
a separate Cargo.toml edit.
Single-lane, sequential plan to land the authforge GUI Keys tab — empty-state
banner with Retry, list of enrolled credentials with per-row remove, modal
TouchDialog driving EnrollOwn against the Phase 3 EnrollmentSucceeded /
EnrollmentFailed signals. zbus uses the glib runtime feature (not the
workspace tokio config), so all async runs on the GTK main thread via
glib::MainContext::spawn_local — no tokio dep in the GUI process.
Eight tasks, ~1 day of work. TDD applies to error.rs (pure logic, 4 tests);
widget code ships with the manual smoke recipe at gui/TESTING.md as the
acceptance gate.
