Provider-aware validation

One model-change contract. No false parity.

A ChangeRun targets one warehouse and one environment. Provider evidence keeps its original method, phase, unit, freshness, and limitations.

Current support stateFoundation

Contracts exist. Authorized warehouse conformance does not.

EXPLAIN and query-evidence contracts are defined; no account connection exists.

Assigned bytes are an upper-bound estimate, not exact credits or spend. The plan can depend on warehouse size.

Account Usage evidence is delayed. Credits and bytes are separate evidence units.

What foundation means

Designed contracts are not released integrations.

Neither platform profile has passed conformance against an authorized customer environment. Missing or privilege-filtered evidence must remain indeterminate, never appear as a silent success.
