AI with boundaries: why architecture comes before the prompt
An architecture guide for using AI models in products without handing rules, state or critical decisions to probabilistic behavior.

IDENTITY. 02 / PRIVACY BY CHOICE
Why Zero?
Sharing the process without giving up privacy.
I tried building in public under my real name before. Over time, I realized that the exposure I was seeking — by sharing financial figures, results and other details — ended up negatively affecting some personal relationships. With a pseudonym, I can share what I consider relevant without exposing my private life.
Zero was created to protect my privacy. That allows me to continue documenting decisions, profits, progress and results without turning every aspect of my life into public information.
CHRONICLE. 03 / A JOURNEY IN PROGRESS
The identity stays hidden.
The journey does not.
Each project is an open chapter: a hypothesis, an attempt and what it revealed for the next step.
This is not a story about getting it right seven times. It is about making every attempt visible and using what it reveals to build the next one.

PROTOCOL. 03 / WHAT WE BELIEVE
Transparency
without posturing.
TestaAí is not a showcase of certainty. It is the ongoing record of one person building things and leaving the reasoning in plain sight.
- 01
Build before explaining.
Ideas only gain value when they meet code, time, cost and someone willing to use them.
- 02
Show what did not work.
Failure is not erased backstage. It becomes data for deciding the next move.
- 03
Use AI without making everything about AI.
Technology accelerates research, design and execution. Responsibility remains human.
TEST PROTOCOL / OPERATING SYSTEM
No formula.
Just process.
Hypothesis
A question good enough to deserve time, money and risk.
→Execution
A prototype in the real world. Small, imperfect and early enough.
→Result
Open data: costs, decisions, wins, failures and what actually happened.
→Learning
The test ends. The experience returns to the system and the next one begins.

0 → 7 systems
Seven different problems, stacks and stages. The goal is not to collect demos; it is to take each hypothesis to the next verifiable operational signal.

The test also
becomes knowledge.
Guides and records connect hypotheses, decisions and evidence, keeping the process useful even when the product changes.
