The Problem: State Poisoning in Ungoverned Vector Memory

Most agent memory frameworks dump raw conversational logs directly into uncurated vector databases. Over multi-session projects, this inevitably creates three compounding failures:

State Poisoning & Compounding Errors: When an agent makes an incorrect guess once, that wrong guess is embedded and recalled as "truth" in all future sessions.
Stale Code Drift: Facts about an architecture stay frozen in memory long after the underlying files have been refactored or deleted.
Cross-Agent Isolation Leaks: Private agent scratchpads bleed into shared team context without hard security boundaries.

The Contrast: Ungoverned Vector RAG vs. MemCore

**Ungoverned Vector Memory:**

Query: "What port does the analytics service use?"
Recalled Chunks (Unfiltered Cosine Similarity):
1. [0.89] "Let's try port 8123..." (Old failed guess)
2. [0.87] "Runs on port 9000 in settings.py" (Stale config from last week)
3. [0.85] "Migrated to port 9440 with mTLS" (Actual current truth)
Result: ❌ Contradictory history dumped into prom
