Bug fixes: - pclntab/rtcorrupt_linux.go: remove duplicate mprotectRW/mprotectRO that broke GOOS=linux builds (they're defined in rtcorrupt_unsafe.go for darwin+linux). - pclntab/pclntab.go: readUint now guards against negative offset (previously panicked via slice out-of-range). - integrity/integrity.go: SetExpectedHashHex now validates length 64 up-front and reports byte index on parse error; added ClearExpectedHash for runtime toggling and test isolation. - transform/mba.go: mbaApplyBinOp used strings.Index on first match instead of the current match; replaced with FindAllStringSubmatchIndex + two-pass replacement. - transform/transform.go: removed duplicate unconditional SplitLongStrings call. New transform passes (CLI flags + Config fields + pipeline wiring): - splice, constblind, mba, fakesigs, funcsplit, bbreorder — all default true. Cleanup: - strenc/keyderive.go: removed unused DeriveFromBinary + buildSeed. - transform/transform.go: removed unused trimFirstParen. - antidebug_hook_darwin.go: modernized readAddr to unsafe.Slice with noescape pattern (vet-safe). Tests (10 packages, 116 tests, all green): - internal/transform: 28 tests covering every pipeline stage. - pkg/strenc: 7 tests for key derivation + XOR stream. - pkg/stringcrypt: 7 tests for CFB round-trip + tamper detection. - pkg/pageman: 14 tests for alignment + mprotect guards. - pkg/integrity: 14 tests including ClearExpectedHash teardown. - pkg/pclntab: 12 tests including readUint negative-offset guard. - pkg/antisandbox: 6 tests for hostname/MAC lists + Check delegation. - pkg/antiemul: 6 tests (1 skipped on non-Linux) for no-panic + timing. Tooling: - Makefile: added test, verify, lint, fmt, vet targets. vet uses -unsafeptr=false (only legitimate uintptr→pointer is the darwin antidebug hook). fmt skips build/ (generated). - README.md: test coverage table + Makefile target reference.
