At a glance

How much Poka reads

B4 Summary. The container and metadata are read and summarised (counts, properties, structure), but the main content is not rendered.

Confidence: medium (the reviewer read the code). Basis: Reviewed 2026-10-26: read parsers/poka-mach-o/src/main.rs (368 lines) and plugin.json. No unit tests or tests/samples.rs; the corpus has no .dylib, .dylib-machO and .bundle-machO sample. Covers .dylib, .dylib-machO and .bundle-machO. The card reads the Mach-O header or universal header and shows the variant, architectures, CPU, file type, load-command count and distinct IDs, segment count, build platform, minimum and SDK OS versions and flags. Judgement: B4: the header is decoded, but segments, libraries and symbols are not listed (the .macho module lists segments and libraries).

What Poka does not read

• Segments, sections and linked libraries are not listed
• Symbols, exports and the code signature are not read
• Code is not disassembled
