Think Speculative Harms Anti Goals
Produces an anti-goals register by assuming a design succeeds at scale, narrating the near-future in which that success harms third parties (including non-users) and is exploited in bad faith by named bad actors, then converting each speculated harm into a standing design constraint bound into the requirements. Use when a feature's success case could externalize harm onto people outside the customer relationship (location, ranking, inference, targeting, automation) and the team's risk review is entirely project-centric. Not a premortem (route plan-survival risk there), not for present documented harms (route to incident analysis), and not a security threat model.
