• File sim/config.go — part of check-in [eda7960b81] at 2026-04-23 19:23:42 on branch trunk — rename module to github.com/danmestas/EdgeSync

  Fix the case-sensitive module path to match the actual GitHub repo URL (danmestas/EdgeSync). Remove tracked leaf/leaf binary and ignore .claude/skills/ scratchpad dirs. (user: [email protected], size: 1609) [annotate] [blame] [check-ins using] [more...]
