fincore.runtime and fincore.extensions

The runtime resolves direct operations, validates inputs, records artifacts, and maintains session-local state. Extensions are discovered as immutable metadata and applied through an ExtensionSnapshot; no process-global plugin registry mutates a running analysis.

from fincore.extensions.discovery import discover_extensions
from fincore.extensions.snapshot import ExtensionSnapshot
from fincore.runtime.catalog import OperationCatalog

Use these APIs when embedding fincore in a larger platform. Domain functions do not require extension registration for ordinary direct use.
