 ## 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.
+
 ### Changes to `.gitea/workflows/release-beta.yml`
 
 #### 1. Linux amd64 Build
 ```yaml
 env:
   APPIMAGE_EXTRACT_AND_RUN: "1"
-  SODIUM_USE_PKG_CONFIG: "1"  # Added
+  # Removed SODIUM_USE_PKG_CONFIG - let it build from source
 ```
 
-**Why:** Forces libsodium-sys to use pkg-config, which finds `libsodium-dev` package installed in the Docker image.
+**Why:** Vendored build is more reliable in CI. libsodium-sys-stable will download and compile libsodium from source automatically.
