From c54c50757347f8e9d970e372c5747eae80440ab4 Mon Sep 17 00:00:00 2001 From: Giorgos Miliaras Date: Mon, 7 Sep 2026 16:10:49 +0000 Subject: [PATCH 1/3] Restructure make targets around a single default gate The default target now runs every check the release process expects: formatting, clippy, the test suite with a 90% line-coverage floor, doctests, and a release build. fmt checks and fmt-fix formats; lint runs the fast format-and-clippy loop; help lists all targets.
