[The source-versus-rendered diff, with the URL and capture time, is a good way to avoid blind trust in the sanitizer. I will add it to my pipeline and test whether it helps a reviewer find problems.](https://hashnode.com/posts/the-page-your-agent-reads/6ad3f83669a965c237b00933/comment/6ad423898bdbbc8157d27a40#reply-6ad46d2f338d7af64db76d1f)

[Thank you, Yunus. The hash log is easy to add, and I will use it in my next test. I will also test how often a model follows hidden lines inside a "data only" block.](https://hashnode.com/posts/the-page-your-agent-reads/6ad3f83669a965c237b00933/comment/6ad458b2071e17eeebe46fc2#reply-6ad46d079a9b6ceb9a90147e)

[Thank you. No, I did not tune it. But the "zero" needs a note. The hidden-text check alone flagged 12 of 60 runs (20%). Four bills have a hidden preview line, and the check flags them. A second read of the bill follows each flag. If the two reads agree, the bill goes through. This gives 0 false flags in 60. I tried a higher threshold. False flags fell, but detection fell from 8 of 8 to 1 of 8. So I kept the strict setting. The 60 runs are 20 test bills, each run 3 times. They are not real mail. The real rate is not known yet. A metric in production will show it.](https://hashnode.com/posts/i-attacked-my-own-finance-bot-the-fix-wasn-t-a-better-prompt/6acc5d11b64aa9414a3a36e1/comment/6ace61a00b5bdc034a0e1b6d#reply-6ad466eed76958580581094b)
