A Marlow challenge · 30 days
Test the dependency classes before rollout
A product revision appears safe on an isolated route. Campaign reporting uses a shared dependency that the narrow canary does not exercise; include the relevant dependency classes before deploying broadly. Choose the scope of the canary, inspect its finding, and gate the broad rollout on evidence that covers the affected product dependencies. Marlow bills by channel, with 25% annual opening contracts. Approval workflow is independent; Campaign reporting requires Approval workflow; Asset library requires Approval workflow; Channel archive requires Campaign reporting and Asset library. Its 3 customer segments and departmental staffing remain active throughout this challenge. Preserve the published cash floor and at least 45% of opening paid customers across the closing window. Ordinary sales, payroll, renewals and support continue; an incident is not the whole business.
