From 23694b558aa5f640d3f3036819c04f8539110336 Mon Sep 17 00:00:00 2001 From: Trey t Date: Sat, 10 Jan 2026 13:27:22 -0600 Subject: [PATCH] docs(09-01): complete scenario A timezone & conflict TDD plan Summary: - Feature 1: Timezone boundary handling (4 tests, all passing) - Feature 2: Same-day conflict detection (4 tests, all passing individually) - Dynamic time buffers enable realistic doubleheaders Commits: -
