# Psy Memory Architecture

Psy memory is structured artifact memory, not chat memory.

## Purpose

Psy memory records:

- checkpoint lineage
- artifact hashes
- source references
- verdict opcodes
- confidence values
- evidence offsets
- feedback opcodes
- false positives and false negatives
- probe results
- training-run metadata

## Non-Goals

Psy memory is not:

- chat history
- natural-language prompt memory
- a live weight-mutation system
- an autonomous patching system

The included `real_pipeline/psy_memory.py` enforces structured event fields and
rejects common prose/chat keys.
