Most of them are cache hits and request logs. Somewhere in there are the errors, each one repeated hundreds of times with a different order number or request ID, so even grep ERROR gives back 4,313 lines. Reading those by hand, or pasting them into a chat with a coding agent, is how an hour disappears. The log in this example is the generated application log from our test fixtures: Java exceptions with stack traces, Python tracebacks, a Go panic, database errors, in the proportions a busy service produces them.
