faucet-cli 1.12.0

#![cfg(feature = "notify")]
//! Integration tests for the notification delivery path (#280) — real HTTP via
//! wiremock. The unit tests in `src/notify/` cover the pure matching /
//! rendering / coalesce decisions; these cover the wire: Slack / webhook /
//! PagerDuty delivery, HMAC signing, PagerDuty trigger→resolve pairing,
//! leading-edge coalescing, and failure-is-swallowed.
