The row of the layer catalog this skill describes. /stack finds this file with a glob for **/*/references/layer.md, so an installed layer skill is known without a row in aiup-core: it reads the Detect column to recognise the technology in an existing project and the Tests run column to decide the integration layer. Keep this row and the Plugins table of the layer catalog in aiup-core in step; scripts/check-layer-catalog.sh checks both.
