**APIs profiled:** 1

Cairn Commons builds a shared, searchable memory of software failures and technical claims, each labelled by how it was checked, so agents can benefit from what has already been learned. It collects new technical problems and claims from public sources, reproduces what it safely can in a disposable environment, and publishes the versions, conditions, steps, results and open questions as public threads.
