Symbol	Kind	Purpose
ErasedTool	interface	Type-erased tool shape the registry executes after parsing at the boundary.
ExecutableTool	interface	One registered tool, typed by its input, output, host context and id literal.
executeInvocation	function	Run one synchronous invocation and record its effects.
InvocationHandler	interface	A named handler invoked by a tool lifecycle step.
RegisteredTool	type	Registered snapshot: public data is retained, implementation helpers are not a contract.
ToolDefinition	type	Configuration form; Support supplies the identity resolver when omitted.
ToolExecutionContext	interface	Execution facts handed to a tool for one invocation.
ToolExecutionEvent	interface	Fact emitted when one tool call settles, correlated by invocationId.
ToolInvocationPorts	interface	Optional tools the lifecycle resolves from the host context for one invocation.
ToolInvocationRequest	interface	One invocation request; the registry supplies signal and diagnostics when omitted.
ToolJournal	interface	Request-local execution receipts; the host decides their domain content.
ToolJournalFinish	interface	Closing record for one tool call, written once with the terminal outcome.
ToolJournalStart	interface	Opening record for one tool call, written before the handler runs.
ToolRegistry	class	Registry mechanism only: visibility, authorization policy, schemas and semantic metadata are host registrations. A registry is mutable until sealed and keeps its own call log.
ToolRegistryOptions	interface	Registry construction options.
ToolRegistryPorts	interface	Host ports a tool registry needs in addition to the tool definitions.
