Internal Routing

Inputs to routing

After validation, the gateway routes the request to exactly one domain owner. Routing is deterministic and version-aware.

• Endpoint path and API version.

• Request intent (resource, verb, and query shape).

• Feature flags for safe rollouts, when used.

This prevents internal services from becoming input-validation layers.

• Sanitizes and validates parameters.

• Enforces required fields and allowed ranges.

• Drops unknown fields when strict validation applies.
