EF 3.1 single score: 1.16 µPt
About 51 seconds of an average person's yearly footprint in these categories. 9 of 16 categories, 72% of the EF weight. Fossil resource use counts the fuel burnt for dutch electricity, not its supply chain; water scarcity uses the aware factor for the netherlands (0.957).

Outcome. Eight subagent runs inside one Claude Code session: two read the café and the public sites, six criticised two drafts (a statement and a plan) twice before they were posted. Reported separately from the session because the session's own record is measured from its transcript, which does not contain these runs.
