In-Memory Memory Adapter

Zero-dependency recall/save adapter backed by a Map. Records vanish on process restart.

When to use it

• Local development.
• Vitest / Playwright tests.
• Single-process demos where users don't need persistence.

When NOT to use it

• Production multi-process deployments — every worker has its own Map; users get inconsistent memory.
• Anything that needs survival across restarts.

For production, use redis() (see the tanstack-ai-memory-redis skill).
