eros-engine-core

Pure-domain types and rules for the eros-engine AI companion engine. No I/O, no async, no database — just data structures and the logic that operates on them.

What's in here

• persona — persona definitions and instance state.
• affinity — the six-dimensional relationship vector with EMA smoothing and decay rules.
• pde — the Persona Decision Engine: rules that decide how a persona responds before the LLM call.
• ghost — proactive (unsolicited) message scheduling logic.
• types — shared IDs, timestamps, and enums.
