Campaign setup
Walkthrough and verdict
The rehearsal proves discovery, policy, the approval path, creative review, changes and the reporting
read-back, end to end in the sandbox. It doesn’t prove capacity holds, ad-server trafficking,
reconciliation, or a paid launch. Record those as gaps, not passes.
To run the seller’s half in one step,
save_test_run answers a practice brief, books a sandbox media
buy and reads delivery back. See Sandbox and
Media buy lifecycle.
