When to write a watch policy
By the end of this lesson, you will be able to decide whether a cost pattern warrants a watch policy, explain how the separate watch engine relates to the built-in rules, and recognise the cases where a policy is the wrong tool.
The signal vocabulary
By the end of this lesson, you will be able to write a signal from the concept, aggregation, operator and window vocabulary, and avoid the exact-equality trap that makes a policy incapable of firing.
Outcomes and the savings basis
By the end of this lesson, you will be able to pick the right outcome type for a watch policy, predict how each is priced, and explain why an un-priceable finding is demoted to advisory rather than shipped at zero.
Evaluation and its limits
By the end of this lesson, you will be able to explain the fail-closed evaluation contract, predict why a watch policy never fires on missing data, and name what is deferred from the current version.
