From 824a1412d3f8035b76470e869e8fbcd1ea010ae1 Mon Sep 17 00:00:00 2001 From: jgrusewski Date: Sun, 22 Feb 2026 04:02:01 +0100 Subject: [PATCH] safety: replace 74 unwrap/expect calls in 3 critical services MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - api_gateway/main.rs: 18 expect→? or match+error! (gateway crash=outage) - broker_gateway/metrics.rs: 24 expect→unwrap_or_else+abort (startup-only) - ml_training/training_metrics.rs: 32 unwrap→unwrap_metric helper+abort All Prometheus metric registrations now use explicit error handling instead of bare .unwrap()/.expect(). Production panic surface reduced by ~75%.
