Memory Hygiene

Memory hygiene refers vers le automatic maintenance processes that keep the systeme de memoire healthy, relevant, and within size budgets. PRX runs hygiene tasks periodically to compact, deduplicate, and prune memories.

Apercu

Without hygiene, memory stocke grow unbounded and recall quality degrades as irrelevant entries dilute search results. The hygiene system addresses this through:

• Compaction -- summarize groups of related memories into concise entries
• Deduplication -- merge semantically duplicate entries
• Pruning -- remove stale or low-relevance memories
• Archival -- move old memories to cold storage

Configuration

[memory.hygiene]
enabled = true
schedule = "daily"  # "hourly" | "daily" | "weekly"
max_entries = 10000
compaction_threshold = 100  # compact when group exceeds this size
prune_after_days = 90
dedup_similarity_threshold = 0.95

Manual Triggers

You can manually trigger hygiene from le CLI:

prx memory compact
prx memory prune --older-than 90d
prx memory stats
