B3 added failing_sources / no_access_sources to schedule-status and
broke test_schedule_status_shape and test_summary_returns_rollup_shape,
both of which assert the payload's EXACT key set. My own tests passed;
these two did not, and integration caught it.
A rule 90 miss: I grepped for the predicates I changed and not for
consumers of the response shape. The shape is the thing I actually
changed.
Both keys added to the assertions rather than loosening them to a
subset check — an exact-set assertion is what catches a key being
renamed out from under a consumer, which is precisely the value these
two tests just demonstrated.
The other readers (PipelineStatusChip, SchedulerStatusBar) pull
individual keys, so they were unaffected. SchedulerStatusBar's prop
comment documented the old shape and is corrected here; a comment that
lies about a contract is worth the same as a doc that does.

D1 scheduler visibility: AppSetting last-tick stamp on every Beat tick +
GET /api/sources/schedule-status (last_tick_at/next_due_at/due_now/auto_sources)
+ SchedulerStatusBar on the Subscriptions tab (re-polled every 30s).
D2 failing-source rollup: ?failing=true on the sources list + FailingSourcesCard
on Downloads with per-source and bulk "retry" (re-runs the feed via /check).
D3 activity sparkline: GET /api/downloads/activity hourly buckets + CSS bar
chart by the stat chips (failures stacked in error color); refreshes on live poll.
D4 credential staleness: surface last_verified age + "re-verify recommended"
warning past 30d; also fixes the dead last_verified_at field-name mismatch so
the verification row renders at all.
