// Goals:
// 1. Decouple store from agent
// 2. Simplify agent creation
// 3. Agent governs data format not store
// 4. Initialization of agent, not store
// 5. DRY initialization in agent, not repeated in each store impl

/**
 * @param {AgentData} [data] Agent data
 * @param {object} [options]

Linkdex

An index mapping block CID to linked block CID.

Characteristics

• Small - just the link blocks - no data for raw leaves. The majority of files are small files, so the DAGs are not super deep.
• Root CID independent - it doesn’t matter what the root CID is, we can just iteratively decode each block in a CAR and index the links it has

What is it useful for?
