The piece argues the 'controlled object' engineers must manage expands beyond code to the whole socio-technical system, requiring four control capability families (Constraints, Sensors/evidence, Controllers/authority, Actuators/corrective action) and four decision-ownership horizons (Organization, Project/Architecture, Delivery, Runtime). It draws on control theory and systems-safety traditions (STAMP/STPA, Simplex) as comparison points, presents the material as an open, evolving research draft, and invites critique rather than presenting finished conclusions. ## Full article daily.dev links to this article rather than hosting it.
