 ## Solution
 
+### Two-Phase Fix
+
+This fix was implemented in two commits:
+
+**Phase 1 (Commit `7316339a`):** Fixed Windows configuration and attempted Linux fixes with `SODIUM_USE_PKG_CONFIG=1`
+- Windows: Changed `SODIUM_LIB_DIR` from `""` to `/usr/x86_64-w64-mingw32/lib` ✅
+- Linux: Added `SODIUM_USE_PKG_CONFIG=1` ❌ (still failed)
+
+**Phase 2 (Commit `44ba1bd4`):** Revised Linux approach to use vendored builds
+- Linux: Removed `SODIUM_USE_PKG_CONFIG` to trigger vendored build from source ✅
+- Windows: No changes (already correct from Phase 1)
+
 ### Revised Approach: Use Vendored libsodium Build
 
 After initial attempt with `SODIUM_USE_PKG_CONFIG=1` still failed (pkg-config couldn't find libsodium.pc in CI containers), switched to the **vendored build** approach: remove all SODIUM_* environment variables and let libsodium-sys-stable build from source.

 **Why:** 
-- Points `SODIUM_LIB_DIR` to the actual pre-built libsodium location (installed by Dockerfile.windows-cross)
-- Explicitly disables pkg-config to prevent conflict
-- Standardizes `SODIUM_STATIC` to "1" (matches auto-tag.yml)
+- Uses pre-built libsodium from Dockerfile.windows-cross (installed to `/usr/x86_64-w64-mingw32/lib`)
+- Explicitly disables pkg-config to prevent conflict with SODIUM_LIB_DIR
