From df6ccdc4ba23703987c277c822a34a2e95995317 Mon Sep 17 00:00:00 2001 From: keyboardDrummer-bot Date: Thu, 23 Apr 2026 14:37:40 +0000 Subject: [PATCH 1/7] Disallow transparent statement bodies (rebased on main) - Add resolution check that disallows transparent statement bodies on non-functional procedures - Add 'opaque' keyword to Laurel grammar with OpaqueSpec category - Add wildcard modifies clause support (modifies *) - Update Python pipeline to use opaque bodies with wildcard modifies - Update all Laurel test files to use opaque keyword - Promote 3 pending Python tests to
