pub async fn gc_stale_facts(&self, mode: CompactionMode) -> Result -} -``` - -**Features**: -- Finds edges with identical: source_id + target_id + relation_type + fact_hash -- Soft-deletes duplicates (keeps oldest, deletes newer) -- Garbage collects facts older than `retention_days` (default 30) -- Supports dry-run mode - -**SQL Queries**: -```sql --- Find duplicates -SELECT array_agg(id ORDER BY created_at) -FROM memory_edge -WHERE deleted_at IS NULL -GROUP BY source_id, target_id, relation_type, md5(fact) -HAVING COUNT(*) > 1 - --- GC stale facts -UPDATE memory_edge -SET deleted_at = NOW() -WHERE fact_invalid_at IS NOT NULL -AND fact_invalid_at < NOW() - INTERVAL '30' day -AND deleted_at IS NULL -``` - -**Expected Results**: -- 5-15% duplicate removal (typical) -- 2-5% space freed from stale GC -- 0 LLM calls (no API cost) -

-**Two-Stage Approach**: - -1. **Pre-filter** (no LLM): - - Find edges with same source + target + relation_type - - Eliminates 60-70% of non-candidates without LLM calls - -2. **LLM Verification**: - - Call LLM: "Are these facts semantically equivalent?" - - Get confidence score (0.0-1.0) - -**Decision Logic**: -- Confidence > 0.95: Auto-merge (keep superset, delete subset) -- 0.70 < Confidence ≤ 0.95: Queue for human review -- Confidence ≤ 0.70: Skip (too risky) - -**Cost Optimization**: -``` -All pairs: 1,000 × 1,000 = 1,000,000 LLM calls (impossible) -Pre-filtered: 1,000 × 5 = 5,000 candidates -After pre-filter: ~100 candidates -LLM calls: ~100 (vs 1,000,000) -Cost: $0.001/call × 100 = $0.10 (vs $1,000 without optimization) -``` - -**Expected Results**: -- ~100-500 LLM calls per run -- 5-10% additional space saved -- 2-5% of facts merged (conservative) -- ~5-10% flagged for human review - -### T3.3: Dry-Run Mode - -```rust -pub enum CompactionMode { - DryRun, // Simulate, don't apply - Execute, // Apply changes -} -``` - -**Behavior**: -- DryRun: Log changes, update audit table (but set `dry_run=true`) -- Execute: Apply changes, write audit logs -
