 21// ReadOnly is one flag with four consequences: a read-scoped token may run
 22// the command, GET /api/v1/read reaches it, it draws on the read rate
 23// budget, and it is not audited. A mutating command mis-flagged ReadOnly
 24// becomes GET-able and unaudited in one line. This test runs every
 25// ReadOnly command against a populated instance and fails on any command
 26// that changes a row (#97).
 27//
 28// Every ReadOnly command needs an entry in readArgs; a new one without
 29// arguments here fails the test rather than going untested.
