Shipping Weekly Without Breaking Production

"Measured by what ships" only holds up if shipping doesn't mean rolling the dice. Our release cadence runs on three non-negotiables: every environment is provisioned from the same infra-as-code, nothing reaches production without passing the same test suite that runs on every PR, and rollbacks are a one-command operation we rehearse, not a fire drill we improvise. Weekly releases are the output of that discipline, not the goal itself.
