@mmmnt/feat-adapter-memory

In-memory event service adapter for Feat: runs deliver-triggered specs (projection, policy, saga) with zero infrastructure. deliver routes an event to the consumer modules you configure; anything a consumer publishes lands in the event log and is captured while the window is open. Delivered stimuli are excluded from capture — only the system's response to them counts. read() returns the full log, which is what contains state assertions check.

Consumer contract: (payload, ctx) => void | Promise<void>, where ctx.publish(event, payload) emits onto the same bus. Module paths resolve from the project root.
