Pack 17 Logs & ops

Logs & ops is regex for the strings operations people read all day: request ids, deploy environments, memory sizes, port mappings, stack trace lines and Kubernetes pod names. Exact lengths matter here, so counted repeats like {12} do a lot of the work.

You begin with request ids like req_3f9a0c1d2e4b, with exactly 12 hex characters after the prefix. Then come environments like prod-2, sizes like 16KB and 2GiB, port mappings like 8080:80, trace lines like at main (app.js:12) and pod names like web-7d4b9c8f6-x2k9p.

Every level also has hidden checks: words you don’t see. Passing the words on screen solves a level; passing the hidden checks too ranks it.

The Field work track works through logs and receipts the same way. Money & finance has more formats where one character too many is wrong.
