Module registry 

First-class integration provider registry: validation, outputs, dispatch.

Validation rules:

1. provider must match a registered Hostable entry.
2. Host-key tables in integration.fields are rejected for IntegrationHosting::Managed and for ConfigScope::GlobalOnly; for ConfigScope::PerHost only hosts in IntegrationHosting::HostBound are allowed.
3. check / up --on <host> requires membership in the host list for host-bound providers; managed providers skip this check.
4. Provider-specific config validation runs on the effective config for the active host.

Functions

config_bool

config_optional_string

config_string

dispatch_resource_kind

is_integration_resource

known_outputs

ops_for

The lifecycle ops for provider, for provisioning dispatch.

ops_for_resource_kind

The lifecycle ops owning resources of kind, for observe/destroy dispatch.

provider_host_keys

The substrate keys that count as host overrides for provider’s config — its declared host-bound hosts (empty for managed providers). The provision path uses this since it has no global substrate list; the authoritative misplaced-block check runs at up/check with the full substrate list.
