Governance & trust
Contracts, audit, metering, tenancy and security.
Governance & trustHow to survive warehouse schema changes without breaking dashboards
Upstream dbt jobs renamed an invoice column to amount_usd, but central semantic mapping and model tests kept dashboards running without a blip.
Governance & trustMulti-tenant customer dashboards: row-level policy isolation
How platform engineers secure embedded customer dashboards using JWT claims, row-level policies, and query metering in a thin semantic layer.
Governance & trustEval harness: agent vs dashboard same-number tests
Create an eval harness that asserts agent answers match dashboard numbers for the same metric requests.
Governance & trustMCP auth: agents never hold warehouse passwords
Set up MCP auth so agents never hold warehouse passwords - credentials stay server-side behind the semantic layer.
Governance & trustProve two consumers return the same number
Run a practical same-number test between two consumers (dashboard and agent) against one metric request.
Governance & trustMetric contracts: the same-number test
A metric contract is a shared definition you can test. If two consumers disagree on the number, the contract failed.
Governance & trustThe engine never opens your warehouse
Why datahashi stopped holding warehouse passwords — compile and execute are different jobs, and agents make the wrong trust boundary expensive.
Governance & trustAudit trails for agent answers
Implement audit trails for agent answers tied to metric requests so compliance can replay who asked what.
