20 days. One feature. Hundreds of failed attempts.

For the last 20 days, I wasn't adding new AI features.
I was trying to make one thing reliable.
Loop 7 is the investigation stage inside TruthLoop AI.
The easy version was generating confident-looking insights.
The hard version was making every conclusion traceable to actual evidence and ending with one clear next action instead of overwhelming users with analysis.
More than once, I thought I had fixed it.
Then the next test broke something else.
At one point I restored older versions just to get back to a stable foundation.
It reminded me that building AI products isn't usually about making the model smarter.
It's about making the system more trustworthy.
I'm finally back to a stable baseline.
Public profile investigations are working again, and I'm rebuilding from there instead of chasing every new feature.
Loop 7 is coming soon.
Not another chatbot.
A truth investigation system designed to uncover the hidden patterns people keep missing.
I'm curious:
What's the longest you've spent building a single feature before you finally trusted it enough to ship?
