What rea standardizes and what it leaves to Ghidra Two stacks under one host band for macOS 26.2 arm64 with Node 22.22.0 and JDK 21.0.12.1. The left stack is rea 6.7.0: the CLI and MCP adapters with 153 commands, 207 tools, and 6 prompts over one BinarySession, the session with one target and one bound provider that the registry selects and never replaces, the Evidence record with 16 fields and an ev_ content hash kept in the EvidenceLedger, the Zod contracts and the error projection with code, category, message, and retryable, and the GhidraProvider and GhidraClient that send JSON lines over bridge.sock. The right stack is Ghidra 12.1.4: ReaGhidraBridge.java as the last post-script, the analyzeHeadless import with the loader chosen from the header, the FunctionManager, ReferenceManager, and BasicBlockModel that found 13 procedures and 39 strings, the DecompInterface with the native decompile binary for mac_arm_64, and the Program database deleted on close.
