Integration examples
Trace the data through the failure.
Four synthetic cases with inspectable inputs, transformations and acceptance conditions.
Time & revisionsReliable ingestionData contractsReliable ingestion
A January cutoff must not select a February revision
Walk through two synthetic FRED-shaped versions of the same observation and reconcile the value visible at a declared cutoff.
Two pages are one batch only after the contract reconciles
Validate a synthetic two-page World Bank-shaped response, preserve page metadata and distinguish retrieval time from publication time.
A missing observation must survive normalization as missing
Follow a synthetic missing-value token through parsing, export and analysis without converting it into an invented zero.
Retry once, validate the whole batch, then advance the checkpoint
Trace an illustrative 429 then 200 sequence with a two-second Retry-After and a maximum of three attempts.
