From 42d2e25e0b31987ae55c31e93c51e848e014e87b Mon Sep 17 00:00:00 2001 From: Tibsfox Date: Sat, 11 Apr 2026 21:40:32 -0700 Subject: [PATCH] fix(cli): handle pnpm global installs by merging both node_modules roots pnpm's virtual-store layout doesn't hoist @gsd/* workspace scopes to the parent node_modules, so the simple symlink-to-hoisted approach from the original fix (#3529) left workspace packages unresolvable. Detect when workspace scopes are missing from the hoisted root and create a real node_modules directory with symlinks from both the hoisted root (external deps) and internal root (workspace packages). A .gsd-merged marker file skips rebuild on subsequent startups. Restores behavioral tests deleted in the original PR and adds unit tests for the pnpm merge path and scope detection logic.
