Prevent generic overrides from bypassing URL SSRF controls.
mergeGenericOverrides accepts caller-controlled spec.upstream.main.url and persists it in the deployment artifact. The gateway converts this value into an Envoy STRICT_DNS cluster without resolved-IP checks. Validate override URLs against the configured backend allowlist and block private, loopback, link-local, and metadata IPs at dial time.

Retain inherited override metadata during promotion.
Line 313 persists only req.Overrides. When a deployment is promoted without new overrides, metadata does not receive baseDeployment.Metadata[constants.MetadataKeyOverrides].
The rendered content can retain the effective values, but deployment retrieval no longer returns the original override document. Initialize the new metadata from the base override document, then deep-merge any new request overrides before persistence.

Extend the deploy path so a caller can customize any field of an API's config for a single deployment, promote an existing deployment across gateways, and expose deployment deploy/read/undeploy to plugins. - DeployRequest gains an optional `overrides` document that is deep-merged onto the resolved deployment definition before it is sent to the gateway, and is persisted with the deployment (so it can be read back and carried forward when the deployment is used as a promotion base). The existing endpointUrl/vhost metadata overrides are unchanged. An override that targets an immutable identity field (apiVersion, kind, metadata.name, spec.context, spec.version, spec.operations, spec.channels) is rejected, so a customization can never repoint or redefine the API — only customize a deployment of it. - Promotion (base = an existing deployment) re-translates the base deployment's rendered artifact to the target gateway's data version, so promoting across gateways on different versions yields a valid artifact. The base API definition is never re-read: the source data version is computed from the base artifact's own apiVersion, and only the immutable artifact Kind is taken from the API record. - pdk.Deps gains a Deployments capability (DeployAPIByHandle, GetDeploymentsByHandle, GetDeploymentByHandle, UndeployDeploymentByHandle), satisfied verbatim by DeploymentService.

Purpose
The deployment API can only override a fixed set of metadata keys
(
endpointUrl,vhostMain,vhostSandbox), promoting an existing deploymentonto a gateway reuses the base artifact without adapting it to the target
gateway's schema version, and external plugins have no typed access to the
deployment lifecycle. This change makes per-deployment customization open-ended,
makes cross-version promotion safe, and exposes deploy/read/undeploy to plugins
alongside the existing Gateways and Projects capabilities.
Goals
without adding a new field per customization.
version produce a valid artifact, without re-reading the API definition.
pdk.Depsfor external plugins.Approach
DeployRequest.overrides: an optional structured override documentdeep-merged onto the resolved deployment definition before it is sent to the
gateway, and persisted with the deployment so it can be read back and carried
forward when the deployment is used as a promotion base. The existing
endpointUrl/vhostmetadata overrides are unchanged.base= an existing deployment) now re-translates the basedeployment's already-rendered artifact to the target gateway's data version,
so promoting across gateways on different versions yields a valid artifact.
The base API definition is never re-read: the source data version is computed
from the base artifact's own
apiVersion, and only the immutable artifactKindis read from the API record.pdk.Deps.Deploymentscapability (DeployAPIByHandle,GetDeploymentsByHandle,GetDeploymentByHandle,UndeployDeploymentByHandle), satisfied verbatim byDeploymentService,mirroring the existing Gateways/Projects capabilities.
