/**
 * Adapter interface for the semantic graph sync engine.
 *
 * An adapter teaches the sync engine how to snapshot a particular data source
 * (files, symbols, API endpoints, calendar events…) and identify records
 * across syncs. The sync engine itself is adapter-agnostic — it never imports
 * or references any concrete adapter. This is enforced by tests.
 *
 * See `.indusk/research/anchor-overlay-pattern.md` Section 7 for the
 * architectural constraint: "the sync pipeline must not know the word CGC."
