Migrate all 92 Python files in qa/ from Python 2 to Python 3: - Update shebangs from python2 to python3 - Replace print statements with print() calls - Fix imports (http.client, urllib.parse, queue, io, functools) - Convert xrange→range, 0L→0, long→int, cmp→key functions - Fix except/as syntax, bytes/str handling, integer division - Use relative imports in test_framework/ package Add qa/run-tests.sh: multi-stage test runner (1183 lines) - Stage 1: Build/binary verification - Stage 2: Security hardening (PIE, NX, RELRO, canary, FORTIFY) - Stage 3-4: Boost/Google test binaries - Stage 5: Library tests (secp256k1, univalue) - Stage 6: RandomX validation (live chain mining + block checks) - Stage 7: RPC integration (skipped: regtest mining incompatible) - Stage 8: Source code invariant checks - Stage 8b: DragonX-specific source checks (11 tests) - Flags: --chain=dragonx, --live-dragonx, --save-release, --quick - Timestamped reports with release archiving to qa/release-reports/ Add qa/clean-test-reports.sh for housekeeping (--keep=N, --dry-run) Fix test build infrastructure: - src/Makefile.gtest.include: fix zcash_gtest→hush_gtest refs, remove 17 stale source files, add LIBZCASH/LIBHUSH/LIBRANDOMX - src/Makefile.test.include: remove stale sources, deduplicate LDADD/CXXFLAGS, add missing libraries - src/gtest/test_checkblock.cpp: add height param to ContextualCheckBlock - src/test/test_bitcoin.cpp: remove JoinSplitTestingSetup (dead code) Add qa/test-reports/ to .gitignore for transient output.
