Inspect selected ELF32/ELF64 PT_NOTE and SHT_NOTE declarations without executing the artifact, retaining independent table identities, source ranges, descriptor digests, GNU build-id/ABI fields and explicit coverage limitations. Integrate mvanhorn's implementation and hardening with current main while preserving byte-entropy registration and the Windows curated regression suite. The maintainer follow-up uses ordinary merges/pushes, not history rewriting. Executed validation: 96 focused/shared/docs tests, complete static/docs checks, eleven real CLI/MCP pairs including GCC ELF32 and Clang big-endian PowerPC64, and two actual Codex task traces checked against their Evidence. Full costs, grader correction and verification limits are recorded in PR #4837. Refs #6262.
