What came of it

What agent-built software does once it has to stay up: the bills and outages, and the parts that work better than anything I shipped alone. Findings first, numbers attached, sources named when the numbers are someone else's.

Two Million Pages, and 12,560 Worth Indexing
A catalogue ingest went from 578,000 track pages to two million in a week. Then I counted: 99.99% of them had never been opened by anyone. Here is what that cost, and the order you have to remove them in.

Every Defect Was a Believable Number
I moved 11,164 symbols onto Alpaca's snapshot API with agents writing most of it, and it went in without an incident. Every defect it did have came back as HTTP 200 with a plausible price attached. Counting is what caught them, not tests.

llms.txt Isn't a Protocol, It's a File
Google says nothing fetches llms.txt. A study of 137,000 sites agrees. Both measured a world where almost nobody links to theirs, and that turns out to be the entire story.
