Delivery Test Methodology
A repeatable protocol needs real run artifacts before a measured claim is made.
Frozen setup
Declare plan, route, endpoint, environment and expected sample before observing outcomes. Document changes instead of merging them into a convenient sample.
Failure coverage
Keep nonreceipt, retries, malformed objects and unknown intervals. Synthetic fixtures test a design only when an actual run records behaviour.
Bounded reporting
Publish compatible event definitions and raw safe artifacts. A route test is neither a strategy test nor a universal reliability certificate.
Record the Claim Boundary
Name the precise artifact and separate documented, attributed, hypothetical and unresolved evidence. These criteria do not assign a star score or certify a provider.
Source Boundaries
Official references describe published mechanisms. BTA's evidence packets and proposed test procedures do not claim a completed paid-feed or account trial.
