"""Tests for the memory consolidation feature in the memory updater.
|
|
|
|
Covers:
|
|
- Candidate selection (category fragmentation threshold)
|
|
- Trigger conditions (min facts, enabled flag)
|
|
- Prompt section formatting
|
|
- Consolidation apply in _apply_updates (guardrails, observability)
|
|
- Normalization of factsToConsolidate from LLM responses
|
|
- Integration with _prepare_update_prompt
