A conditional write fails if someone already holds the number, so two workers never leave with the same one.
Webhooks are fast but unreliable. A scheduled sweep re-reads the source and catches what they missed.
A construct attaches the alarms by default, each linked to the runbook for that failure.
Mid-incident, nobody should be choosing between six flags. One switch halts trading.
When our feed drifts from an independent exchange, the price never reaches a customer quote.
Auth, caching, and data loaders in one place, so each frontend gets exactly the shape it needs.
Fulfillment keys off the provider's event ID, so a duplicate callback does nothing.
Every run is token-accounted, so cost and accuracy get tracked together.
Synonyms and near-duplicates collapse into one canonical tag, so search finds what people mean.
An undeclared failure or missing service is a compile error, not a 3am page.
Every input is recorded, so a run can be replayed and must come out identical.
Every call records which rule matched, so coverage is measured instead of assumed.
