 ### Fixed
 
+**CI/CD Infrastructure:**
+- **Fuzz Workflow Failures** (commit 57894a9):
+  - Fixed GitHub Action reference: `dtolnay/rust-action` → `dtolnay/rust-toolchain@nightly`
+  - Added `fuzz` to workspace exclusions to prevent build conflicts
+  - All 5 fuzz targets now compile and execute correctly
+  - Impact: Weekly fuzzing and manual fuzzing workflows now functional
+- **Documentation Build Failures** (commit d10587b):
+  - Fixed 3 unresolved rustdoc links in `wraith-core/src/node/node.rs`
+  - Added `Self::` scope qualification for method references
+  - Impact: `cargo doc` now builds without warnings
+- **Cross-Platform Integration Tests** (commit d10587b):
+  - Fixed macOS/Windows test failures (os error 10049) in `test_connection_establishment`
+  - Modified `listen_addr()` to convert unspecified addresses (0.0.0.0/::) to loopback (127.0.0.1/::1)
+  - Ensures returned addresses work as connection destinations on all platforms
+  - Impact: All integration tests now pass on Linux, macOS, and Windows
+- **Padding Fuzz Target Crash** (commit 528b9fa):
+  - Capped `plaintext_len` to 16,384 bytes (maximum padding size class)
+  - Prevents unrealistic allocation attempts (fuzzer found 72 PB input causing crashes)
+  - Improved fuzzing efficiency by focusing on realistic packet sizes
+  - Impact: Padding fuzz target now passes with 354,181 executions, no crashes
+
 **Test Stability:**
 - Marked `test_multi_peer_fastest_first` as `#[ignore]` - Flaky test due to timing sensitivity in performance tracking
 - Test is non-deterministic due to scheduler behavior and performance measurement timing
