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.
