memory-guardian

Workspace memory lifecycle system. Dual-layer Bayesian decay + four-state quality gate + case lifecycle + compaction.

Design Principles

1. Check status before any write — memory_status first
2. Dry-run before apply — preview destructive operations
3. Default behavior > toggles — workspace defaults from MG_WORKSPACE
4. Write ordering > content correctness — sequence matters
5. Observable but not brittle — signal degradation → WARNING, not crash
6. Single source of truth — all defaults in mg_schema/meta_defaults.py
