+"""DSA model + MTP (EAGLE) speculative-decoding server fixture.
+
+Variants combine `DsaMtpServerBase` (server lifecycle) with
+`DsaMtpEvalConfigDefaults` (shared eval thresholds/params),
+`GSM8KMixin` and `SpecDecodingMixin`, then set `model` and per-variant
+overrides (`enable_dp_attention`, `mem_fraction_static`, `bs_1_speed_thres`).
+
+Example:
+    class TestDsv32DP(
+        DsaMtpServerBase,
+        DsaMtpEvalConfigDefaults,
+        GSM8KMixin,
+        SpecDecodingMixin,
+    ):
+        model = "deepseek-ai/DeepSeek-V3.2"
+        enable_dp_attention = True
+        bs_1_speed_thres = 90
+
+The base itself is NOT a runnable test (no `test_*` methods until a subclass
+mixes in the kits), so unittest discovery picks it up as empty.
