TESTER_VERBS gains usage, names, limits, plugins, instances, project.list,
thread.list, name.set and project.create; TESTER_ORGANIZATION_VERBS lets a
tester read limits, plugins and instances and send plugins.set,
instances.set and routes.set, each logged with actor tester. The project
file verbs refuse a tester tester-refused. The broker and CLI drop the
[mos test] prefix rule (mos-0872 Q1). The CLI takes --tester on the seven
reads and the W1-W7 write forms and refuses it (exit 4) elsewhere.
project init --tester checks the project area, binds the tester with one
agents read, then commits the layout as tester (mos-0872 Q2).
