Reject Mach-O and ZIP entries whose metadata no longer matches the reader inventory, preventing a sibling adapter key from selecting bytes under another entry. Reuse the existing ASAR metadata snapshot and equality rules and read Mach-O ranges from owned records.
Move the real system-lipo test to the provider boundary suite, release its reader, and derive slice expectations from the host FAT table.
Validation: 68 focused artifact, ASAR and MCP tests plus ZIP cancellation passed. Real macOS lipo was exercised against /bin/ls; Ghidra, IDA and other deep providers were not run. Static, docs, architecture and test discovery checks passed.
