Event outcomes

Marking also supports evidence-backed final outcomes.

The outcome lane is designed for questions such as:

Did this event happen?
What was the final result?
Which attestation should an application use?

Routes:

GET  /v1/sports/coverage
GET  /v1/sports/events
GET  /v1/sports/events/:eventId
GET  /v1/sports/events/:eventId/attestation
POST /v1/attestations/verify

Each attestation binds:

  • event identity;
  • resolution policy;
  • evidence root;
  • final or corrected outcome;
  • issue timestamp;
  • Marking signature.

Applications should fail closed on mismatched events, missing evidence, invalid signatures, stale/superseded attestations, or unresolved ambiguity.
