- Checkpoints_tests: align with the checkpoint map refreshed 2026-07-01 (2186940 pin superseded by 2205000/2206004 pins). - wallet_tests: make abandon_not_from_me self-sufficient; add_coin() never populated mapWallet, so the test provisions its own not-from-me tx. - DoS_tests: RFC 6979 deterministic-signing fix (from prior audit session). - http_seed_tests: correct chunked-body byte math in dechunk_split_at_awkward_boundary (\r\r\n is 3 bytes, not 2). - onion_v3_tests: .onion.onion fix (from prior audit session). - time_drift_tests: post-fork drift limit is 90s (main.h), not 180s. - consensus_safety_tests: new suite pinning consensus constants (MAX_REORG_DEPTH, MAX_MONEY, fork heights, fee floors, etc.). - CMakeLists: TEST_DATA_DIR definition quoting fix.
