Providers and models

Agentweaver.Abstractions names 15 provider seams. A seam defines a contract boundary. It does not prove that an adapter or running service exists.

ProviderDescriptor records the seam, provider ID, adapter version, options-schema version, hosting pattern, and advertised capabilities. It contains no option values or credentials.

ProviderCatalog.Create validates registrations, defaults, allowed overrides, ordered sets, and network-policy layers. ProviderResolver checks cardinality, versions, options schemas, and capabilities.

The Probe supplies existing target IDs, generation, and ResourceNegotiation. The resolver selects and pins against those values; it does not provision or live-negotiate a resource.

Cardinality	Seams	Resolver status
Exclusive	Sessions, Snapshots, Sandbox, Storage, Memory, Source Control	Resolve and Pin support this form. Snapshots can resolve to explicit None.
Platform singleton	Policy, Secrets, Messaging, Object Store	Resolve and Pin support this form. Projects cannot replace the provider.
Ordered composite	Guardrails, Telemetry	ResolveOrdered and PinOrdered preserve the selected order.
Layered	Network Policy	ResolveNetworkPolicy and PinNetworkPolicy support required L3/L4 and optional L7 layers. Pinning requires a matching applied intent generation.
Keyed by meter source	Cost	Not implemented.
Per application	Application Hosting	Not implemented.

Pinning records provider identity, adapter version, options revision, resource generation, and negotiated capabilities. It does not provision a resource or enforce policy.

The Foundation Probe registers azure-key-vault, azure-blob, and azure-monitor descriptors for its checks. These registrations do not form a product provider catalog.

Model is not a provider seam. The v1 source contains no AgentHost, model resolver, or model adapter. It does not declare support for a model vendor.
