User Memory Formats

Four progressive formats:

Simple Notes — atomic facts, O(1), but connections are lost;
Enhanced Notes — paragraphs with full context, semantic integrity, but redundancy;
JSON Cards — category/subcategory/key-value hierarchy, partial updates, but rigid classification;
Advanced JSON Cards — fact + backstory + person + relationship + timestamp, disambiguation (“Dr. Zhang” — user’s dentist or father’s cardiologist?).

Selection criterion: few key ones — Advanced Cards; many massive ones — Simple Notes.

Advanced forms: executable code (User as Code — aggregation and constraint checking with deterministic code) and parameterized memory.
