+# RADE Integration Verification Report
+
+## Application Under Test
+
+| Field | Value |
+|---|---|
+| Application name | FreeDV |
+| Application version / git hash | 3.0.0-dev (git 69473b0) |
+| Platform (OS + version) | macOS 26.6.2 (25G83) arm64 (loopback)<br/>macOS 26.6.2 (25G83) x86\_64 (OTAC) |
+| Tester name / callsign | Mooneer Salem / K6AQ |
+| Date | 2026-09-16 |
+| radae repo commit hash | 758e825182f3a216922fb4bbd7f9a4f5c6fe4288 |
+| rade\_c repo commit hash | 7eda42f0f10ec5df6ff409527f5855d5b3ed1c94 |
+
+## Signal Path Declaration
+
+- [x] No additional signal processing (AGC, noise gate, resampler, EQ,
+      compression) between WAV file input and RADE encoder input during
+      this verification test
+      <!-- Asserted automatically: test/freedv-ctest-loss.conf.tmpl disables
+           AGC, the mic/speaker EQ and Speex noise suppression, and the RADE
+           path runs at a fixed 8/16 kHz with no resampling. -->
+
+## Baseline Loss (Step 1)
+
+Re-run with the current repository version before filling in this section.
