Words made simple

A few useful meanings before you read the explanation.

State
The data describing where a workflow is now, what it already knows, and what still needs to happen.
Durable
Able to retain progress and recover across interruptions. Durable workflows require appropriate storage and retry behavior.
Trace
A linked record of the steps in one request, including model calls, retrieval and tools. It helps locate delays or failures.
  • Trace calls and state transitions, correlate across services/queues, record usage and evidence IDs, and link to business receipts.
  • Audit important actions separately with authenticated actors and durable outcomes.
  • Redact sensitive content and set appropriate retention.

Questions dashboards should answer: Which task failed? Why? For whom? Which source/model/prompt version? What did it cost? Did an external action occur? Is any outcome unresolved?
