Five rewrites of one routing rule
My agent runs on Grok and hands heavy code to Claude Opus 5. Five rewrites of its routing rule in one day: wording fixed four misroutes, and the last one needs a gate in code.

My config said Opus
My eval config said Claude Opus 5. The child ran on gpt-5.5, because the API key was out of credits and a fallback answered in the same second. The fix is a preflight and reading the model from the run record.

14 of my 22 tests were in training
A contamination audit found 14 of my 22 eval prompts word for word in the training data, and 5 more as near copies. I built a held-out set of 21 clean tests and a promote rule that needs both.

46 cron lines named a time zone
46 of the 75 jobs in my crontab set TZ= inline. In cronie that only changes the job environment; when a job fires comes from the host clock or CRON_TZ. On 1 Nov the difference shows.

11 leak alerts, 0 leaks
My two public plugin libraries push straight to main. The first leak scan raised 11 alerts and found 0 leaks. The one real policy hit came through a path with no check, so now a gate scans every commit every 15 minutes.

The best thing my fine-tune learned was to wait
Asked which sign the Sun was in on a date, a 3B base model answered from memory and was wrong twice. The fine-tune calls the lookup tool with the right date in 5 of 5 date prompts and states nothing first.
