+# 020 — Alerts webapp UI
+
+## Summary
+
+A webapp page for managing `AlertRule`s ([017](017-ntfy-alerts.md)) end to
+end: create/edit/enable/delete rules and configure their ntfy sink, without
+touching `settings.json` by hand.
+
+## Scope
+
+- A new route/panel (matching how `Dashboards`/`Metrics` are already surfaced
+  in `App.tsx`) listing existing alert rules: name, condition summary,
+  enabled state.
+- A rule editor:
+  - Condition type picker (Immediate / Threshold / New value / Ratio, see
+    [018](018-alert-trigger-evaluation.md)) with type-specific fields, reusing
+    `FilterBar`'s query input for the query-based conditions rather than a
+    separate text field.
+  - Ntfy sink fields: topic and optional server override.
+  - Enabled toggle.
+- "Send test notification" button wired to the sink delivery endpoint from
+  [019](019-ntfy-sink-delivery.md), so a topic/server can be verified without
+  waiting for a real trigger.
+- Contextual "?" help icons on the condition-type picker and sink fields,
+  matching [021](021-docs-contextual-help.md)'s pattern.
+
+## Acceptance criteria
+
+- Rules created/edited/deleted in the UI persist across a page reload (i.e.
+  round-trip through the CRUD endpoints from 017).
+- Each condition type's fields validate before save (e.g. Ratio requires two
+  queries and a threshold).
+- "Send test notification" delivers to the currently-entered topic/server
+  without requiring the rule to be saved first.
+
+## Depends on
+
+- [017 — Alert definitions & settings persistence](017-ntfy-alerts.md)
+- [018 — Alert trigger evaluation](018-alert-trigger-evaluation.md)
+- [019 — Ntfy sink delivery](019-ntfy-sink-delivery.md)
+- [021 — Docs contextual help](021-docs-contextual-help.md)
