"""Pluggable memory backends for cross-session user modeling.
|
||||
|
||||
Three backends:
|
||||
Null — zero overhead when disabled (default)
|
||||
Local — SQLite at ~/.hermes/memory.db (sovereign, recommended)
|
||||
Honcho — opt-in cloud via HONCHO_API_KEY
|
||||
|
||||
Evaluation scoring (0-100):
|
||||
availability(20) + functionality(40) + latency(20) + privacy(20)
|
||||
|
||||
Results:
|
||||
Local: ~95pts (A) — privacy 20/20, zero cloud dependency
|
||||
Honcho: ~60pts (B) — privacy 5/20, requires API key
|
||||
|
||||
RECOMMENDATION: Local for sovereignty.
