Boundary normalization for flaky upstream integrations

Summary#

Problem#

External providers and partner APIs often violate idealized contracts at the edges, such as returning mixed image dimensions in one batch or omitting client-attribution metadata, which can crash internal batching or break observability/billing.

Solution#

Normalize and enrich data at the integration boundary before core processing: resize or coerce inconsistent payload items to a canonical shape, forward provenance headers through a shared helper, and apply safe defaults when callers do not identify themselves.

Failure Modes#

Assuming upstream payloads are perfectly uniform and letting batch ops like stack fail at runtime
Duplicating outbound header logic across callsites so attribution/security headers drift
Relying on callers to always send optional metadata instead of defaulting defensively
