Traces

Traces are the execution record returned by the runtime.

Why this exists

You need to know more than whether the run succeeded. You need to know:

• how many attempts happened
• what result was produced on each attempt
• which verifier rejected or accepted the result
• why a failure happened

How it works

The current trace includes:

• goal
• capability
• startedAt
• finishedAt
• status
• attempts
• failureReason

Each attempt records:

• the candidate result
• capability verification outcome
• operator verification outcome
• accepted or rejected status

Example

console.log(execution.trace.status);
console.log(execution.trace.attempts);

Notes

Current

The checked-in browser integration test asserts both the accepted result and the trace contents.
