+**65** fake payloads: **35 java** + **30 native** (`crash_java_*.json`, `crash_native_*.json`).
+
+Regenerate:
+
+```bash
+python3 ../generate_test_reports.py
+```
+
+Batch upload (all):
+
+```bash
+../upload_test.sh
+```
+
+Upload only native:
+
+```bash
+ONLY=native ../upload_test.sh
+```
+
+Native clusters use signals `SIGSEGV`, `SIGABRT`, `SIGBUS`, `SIGFPE`, `SIGTRAP`, `SIGILL` with shared fingerprints per crash family (see `generate_test_reports.py`).
