My monitoring pinned a 3am outage on Cloudflare within seconds, and my notes said my phone was paged at 03:37. Nothing had been sent, ever.
My project keeps a lessons-learned file. Going back through my notes, I found the same pattern five times: the lesson gets written down, and the repeat comes anyway.
My notes vault appeared to delete itself, git recorded 146 deletions that never happened, and OneDrive forked 120 conflict copies. Nothing was lost, and the warning was in the manual all along.
I published a post warning that SQLite on an ephemeral filesystem silently loses your database. Hours later, my own app turned out to have been doing exactly that on every deploy.
