Experimental. Build with Digdir's Designsystemet correctly on the first attempt: quote-verified component contracts (twins), a WCAG guard hook, and the /ds-check audit command.

Diagnose recurring organisational and team dysfunctions (stuck decisions, hollow agile rituals, metric-chasing, disengagement, change that never lands) using open sociotechnical systems theory and the DP1/DP2 design-principle lens.
