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-iptables-save/src/main.rs (281 lines) and plugin.json. No unit tests or tests/samples.rs; the corpus has no .iptables, .ipt and .iptables.rules sample. Covers .iptables, .ipt and .iptables.rules. The card shows the generator, tables, chain count and built-in chain policies, -A and -I rule counts, the top targets and protocols, referenced ports, match modules and COMMIT lines. Judgement: B4: the content is summarised by counts, but the entries themselves are not shown.

What Poka does not read

Rules are not listed or explained
Chain policies are shown, but per-chain rule order is not
Packet and byte counters are not shown
