"""The t7log bundle (goal 41 T7, ux-notes structural bet 3): the task
page <-> event log unification. The two surfaces are ONE investigation
flow: the task page mounts the log as its "Event log" tab (the same
task-log-feed partial the standalone /tasks/{id}/log route renders),
the entrypoint publishes both slots, and no link to the log opens a
new tab any more.

Fixture-driven like the pages bundle: a task + session are inserted as
rows, events land through the push wire (/api/saddle/chunks), and the
assertions read page HTML, entrypoint slot state and the SSE stream.
