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: high (the reviewer read the code and a test that proves the claim). Basis: Reviewed 2026-10-26: read parsers/poka-zoo/src/main.rs (386 lines) and plugin.json. the_corpus_zoo_states_its_live_entries_and_declared_size checks the corpus sample.zoo against figures read separately, and a second test covers the walk. Covers .zoo. The tree shows the Zoo version, file count, totals, ratio and methods, and lists the members (deleted ones counted apart). Judgement: B4: the archive is listed but no member is extracted or shown.

What Poka does not read

  • Member contents are not extracted or shown
  • Long file names and directory names (from the extended entry) are not read; the 8.3 name is shown
  • Comments, dates and CRCs are not shown
  • Caps of 1,000 members and 3,000 nodes
