- [A Name Isn't an Identity](https://dataparade.io/posts/a-name-isnt-an-identity/index.md): A code scanner finds a hundred places where something called email appears. How many data items is that? Joining on the name alone dropped our grouping precision from 86% to 51%. The fix was to stop trusting names and join only on evidence the parser can show you. (2026-10-14)
- [A Decision Model That Walks the Parse Tree](https://dataparade.io/posts/a-decision-model-that-walks-the-parse-tree/index.md): Sorting data item mentions into data items is an agent task: look at a candidate group, read around it, decide. A frontier coding model does it well and costs too much to run on every scan. We built the same loop around Jev, gave it parse-tree tools instead of a file viewer, and it landed above the… (2026-10-08)
- [Your Coding Agent Already Knows Where the Password Went](https://dataparade.io/posts/your-coding-agent-already-knows-where-the-password-went/index.md): Every decision about how a system handles personal data now gets made in a conversation with a coding agent, and the transcript is sitting on disk. We wrote a tool that reads those transcripts. The next step is an interviewer that forms a hypothesis from them and asks you to confirm it, instead of… (2026-10-02)
- [We Labeled Six Repos with a Thousand Sub-Agents](https://dataparade.io/posts/we-labeled-six-repos-with-a-thousand-sub-agents/index.md): You cannot improve a scanner you cannot score, and nobody had labeled where the personal data lives in a real codebase. So we had three sizes of model label it, argue about it, and let the biggest one arbitrate. The labels are not perfect. They are a compass needle, and the first thing they found w… (2026-09-29)
- [The Diagram Is a Projection](https://dataparade.io/posts/the-diagram-is-a-projection/index.md): A dataflow diagram is not the output of a scan. It is a query over a knowledge base, and the gaps in that knowledge base tell you exactly which questions to ask a person. We built an interviewer on that idea. It drew its first system-context diagram after one question. It also makes dumb decisions,… (2026-09-17)
