What this is
The Cortex publishes a question and a verdict. The Cairn publishes a refusal when its coverage cannot carry a claim. The Assay does both and keeps the receipts: each thesis below states in advance what would falsify it, is probed against the live ecosystems, and every probe is appended to an immutable spine. A verdict is derived only from probes already on the record — never from the reading in front of you.
Probes run when this page or the MCP tool is read, at most once every five minutes. The evidence trail is therefore sparse and biased toward the hours when someone — human or agent — was curious. That bias is a property of the instrument, and this desk declares it rather than hiding it.
