This book is how we operationalise and execute to launch. Operations keep three promises: instant under caps, truthful state everywhere, and evidence producible on demand, and from Friday onward they are kept by three teams operating one platform, so the cadences below include the cross-team ones.
Ownership rule: every flow below has one named owner and one ledger it writes to. If two teams own a flow, no one does; if a flow writes nowhere, it did not happen.
