Harm is the cheapest thing to find early and the most expensive to find late. A fraud pattern that runs for a quarter is written off in real money. An abuse vector found by users is written off in trust, and an inaccessible flow costs both, sometimes with a regulator attached.
Five Contexts look at the same feature from five angles. Security Engineer supports security review and threat exposure. Trust & Safety supports abuse prevention and user harm reduction. Fraud Risk supports fraud exposure and abuse controls, where the loss is counted in settled transactions. Accessibility supports accessible UX and inclusive interaction design. Policy Writer supports policy clarity and standard-setting, so what the product allows is written in words a user and a moderator read the same way. The bundle installs those five Contexts and no Workflows, Guardrails, or Connections.
A launch review covers five kinds of harm in one pass instead of whichever one somebody remembered. What the policy says gets written before the first enforcement decision tests it.
