Research Data Stack Feedback: evidence

Define schema, missingness, webhook, and audit requirements before integration begins.

Illustrative synthetic evidence · No customer outcome claim · Live execution not certified

Provenance and limitations

Illustrative product view using synthetic data. It is not a customer result or outcome claim.

Connectors and exports must retain documented status and limits.

Availability: beta. Evidence status: template ready.

Remaining gap: Versioned golden exports and redacted webhook/warehouse fixture lineage exist; no connector, external delivery, or authenticated audit capture has been verified.

Timestamps and hashes identify checked-in materials. Scoped authenticated local runs have explicit receipts and source revisions. Deployed execution and external delivery require separate evidence.

Setup, analysis and decision handoff

Research Data Stack Feedback: public template setup preview. This is not an authenticated editor or respondent run.

Research Data Stack Feedback: readable synthetic fixture v1/audit/warehouse-delivery.json. This is an artifact preview, not live product execution.

Synthetic artifact handoff

Inspectable fixture contracts and scoped local product receipts. Each artifact states its provenance and remaining limitations. Deployed connector delivery, authenticated public sharing and production reports remain uncertified.

Readable receipts and fixture contracts (5)

v1/audit/warehouse-delivery.json

The schema, missingness, webhook, and warehouse audit are synthetic fixtures; no warehouse connector or external delivery ran.
