Feature Toggle Admin is the feature flag control panel, 5 flags in a ruled list each showing the flag key in a mono pill, environment badges (Prod, Staging, Dev), a rollout progress bar with the percentage (0% for bulk_moderation_ actions through 100% for export_csv_v3), a kill-switch Switch, and the last-changed-by credit with avatar and timestamp. The real_time_presence flag ships with its kill switch enabled. A callout above the list states the precise operational contract: kill switches take effect within 10 seconds, globally, across all regions and replicas, with no partial rollout window during activation. The audit footer closes: all flag changes are recorded and cannot be undone silently.
Flags are one typed array; the environment badge list is driven by a FlagEnv union so adding a new env only touches the lookup record, not the render. The callout text is not decorative; it is the contract.
Reach for this block on the engineering admin panel, wired to your feature flag service. Guard kill-switch toggles with a confirmation step before the Switch fires to avoid accidental global shutdowns.

Tip: the 10-second global propagation callout is not a disclaimer, it is the information an on-call engineer needs at 2am; keep it prominent and unambiguous.
