"No" is part of the product.
Every refusal is archived, dated, and made visible. The ledger is short because the house is small — not because we accept everything.
Predictive policing
A municipal request to forecast crime by neighborhood and allocate patrol. Refused on first reading — the instrument does not assign moral weight to a population before any act has occurred.
Insurance pricing in violation of LGPD
An optimization that would, in practice, deny the data subject the right to contest an automated decision. Art. 20 reserves that contestation as a fundamental right.
Partisan electoral targeting
Segmentation to optimize partisan messaging in the 2026 cycle. Out of scope by stated policy — the instrument is not an electoral targeting platform.
Workforce attrition without consent
Simulating layoffs under restructuring scenarios without the workers' knowledge or consent. Returned with an explanation and an alternative scope.
Optimization of an addictive product
Cohort calibration to maximize compulsive usage time. The instrument is for observation — not for manufacturing dependency.
An instrument that refuses, refuses in public.

When a population earns or loses a seal, or a new real outcome is measured against the engine, we write once. No newsletter cadence — only new entries in the ledger.
