qa-fuzz-testing

Structure-aware coverage-guided fuzzing: 3 reference skills (corpus-management-reference, sanitiser-integration-reference, crash-triage-reference) + 7 per-language fuzzer skills (libfuzzer-cpp, afl-plus-plus, go-native-fuzzing, cargo-fuzz-rust, atheris-python-fuzzing, jazzer-jvm-fuzzing, ossfuzz-integration) + 1 dispatcher skill (fuzz-toolkit-dispatcher) + 2 agents (fuzz-target-author, fuzz-findings-critic). Distinct from qa-property-based (hypothesis-driven + shrinking) and qa-api-testing/schemathesis-fuzzing (API-layer); this is binary/system-level coverage-guided fuzzing.
