+# 017 — Ntfy.sh alerts (future idea)
+
+> The README lists this under "Ideas... that can be implemented in the future, but
+> not now." Not scoped for current implementation — tracked here so it isn't lost.
+
+## Summary
+
+Let users configure matchers of interest and an ntfy.sh channel, and send a
+notification to that channel when a matching event occurs.
+
+## Scope (sketch, not final)
+
+- Matcher definition, likely reusing the FilterBar query language
+  ([005](005-filterbar-pest-parser.md)) or the metric declaration language
+  ([002](002-metric-declarations.md)) rather than inventing a third syntax.
+- Ntfy channel config, persisted via settings ([008](008-settings-model.md)).
+- Trigger evaluation on log ingest (engine-side, to avoid re-scanning) or on bucket
+  update, sending an HTTP request to the configured ntfy.sh channel.
+
+## Depends on
+
+- [008 — Settings model](008-settings-model.md)
+- [005 — FilterBar pest parser](005-filterbar-pest-parser.md) (likely, for matcher
+  syntax reuse)
