模型与交互

符号	类别	用途
bindInteraction	function	Bind every registered transfer command to a local handler. Models cannot add handlers.
Command	interface	Compiled command.
CommandCatalog	class	Mode and cross-protocol field ownership checks are shared by all receiving hosts. The catalog seals itself as soon as construction finishes, so a run cannot register a new command later; set remains available only for the superclass installation pass.
CommandCatalogOptions	interface	Envelope-level options for a command catalog.
CommandDefinition	interface	Declarative command shape before compilation.
commandSchema	function	Build a JSON schema for one command id. Prefer compiled schemas; retain the existing open-schema contract for dynamic host protocols. A protocol without fieldSchemas falls back to an open object that only pins the discriminator, which keeps legacy hosts working without weakening compiled ones.
compileCommands	function	Compile a whole catalog with shared envelope fields. Applications declare only their own data and handlers. Defaults are merged in this order: unrelated default keys, then the command's own keys, with fields, checks and tags concatenated so shared envelope checks always run before per-command checks.
defineCommand	function	Compile declarations once. Parsing is synchronous and never executes a registered tool. Two schemas are produced from one declaration: modelJsonSchema marks only fields the model must fill, while inputJsonSchema marks every required field. A discriminator, when present, is prepended as a required constant field.
defineCommandCatalog	function	Compile definitions and wrap them in a sealed catalog.
defineInteractionProtocol	function	Construct a protocol from one definition.
INTERACTION_CATEGORIES	constant
InteractionCategory	type	Interaction purpose, never an authorization level or an assertion of execution success.
InteractionDescriptor	interface	Catalog metadata for one command, independent of its field shape.
InteractionHandlers	type	Handler map keyed by command id; each handler receives the parsed value and App context.
InteractionProtocol	class	Web/AI payload family. HTTP/SSE framing and actual command execution remain separate ports. Every command registered here gets the envelope's discriminator forced to its own id, so a payload cannot claim one command while carrying another command's data.
InteractionProtocolDefinition	type	Transfer envelope plus its registered command family; no change to HTTP or SSE framing.
ProtocolCheck	interface	One declarative rejection rule.
ProtocolField	interface	Field presence, schema and ownership are declared together; schemas describe model input.
ProtocolPredicate	type	Predicate evaluated during validation; any truthy result counts as a failure.
ProtocolReason	type	Lazy rejection wording: a fixed message, a pre-built error, or a factory bound to the value.
ProtocolShape	interface	Custom protocols may derive dynamic keys without supplying a compiled schema.
RegisteredProtocol	interface	Runtime extension contract; hosts retain their own version values and validation context.
