Your trace UI can hide a secret that SQLite still stores
I made a tiny trace store hide a fake token in its display. Then I opened the database through a fresh connection. The token was still there. So was a made-up confidential sentence. The redaction worked exactly where I put it. That was the problem. 🫠 A current DEV discussion about secrets in coding-agent context has a useful thread on canaries: harmless markers placed in a nonproduction workflow…
A developer demonstrated how a trace store can hide sensitive information like tokens while still storing them in a database. Using SQLite, they created a synthetic event with an operation, status, token, and confidential prose. The trace was displayed, but the token and prose remained visible in the database. By comparing the raw database row and the displayed trace, they confirmed that the token was present and the prose was retained.
This example highlights the importance of proper logging practices and the potential risks of exposing sensitive data even when it appears hidden in trace views.
