Press release ingestion

Choose a release feed using concrete acceptance cases

Match the required announcement type before counting records. Use these concrete cases to avoid treating company-symbol APIs and broad wire channels as identical.

Worked acceptance sheet

5 records
Routine private-company releaseWire RSS / publisher feed / source streamRelease metadata with issuer and stable identityNot established by a listed-company symbol query.

Named-wire metadata querynewsfilter source.id:prNewswireReturned source ID, record ID and source linkDocumented query; authenticated response not called.
PR Newswire / GlobeNewswire stream monitoringSynoptic named Tier 3 streamsAPI-enabled stream metadata, then permitted reader responseCatalog metadata observed; post response requires access.
Correction replay behaviorLocal RSS-file workflownew -> replay -> correction -> old replayEight offline tests include durable-state CLI behavior.

Next task for a developer

Run the complete RSS conversion, inspect its expected JSON and exercise correction handling. These tasks produce working local artifacts before any vendor credential is available.

What a real feed trial still needs

Use your required issuer types, languages and wires. Record account restrictions separately from missing items. Audit financial tables and attachments only when entitled to their content. No result in this guide claims complete wire recall or measured arrival speed.
