# AgentMemoryOS Shadow Mode Acceptance Verification Report
# Date: 2026-06-13

## 1. Executive Summary
The AgentMemoryOS v0.3 $\\to$ v0.4 transition has undergone Shadow Mode verification (Phase 1: Silent Mirroring). The system is operating in parallel with Legacy Memory, collecting recall and latency evidence.

### Verdict: **GO (With Watch)**
The core logic for shadow monitoring and evidence collection is verified and stable. Current data shows high stability, though a small sample size of production-like queries is currently recorded.

## 2. Stability Metrics (Verification Evidence)
Based on the shadow recall logs and automated test suites:

- **Unit Tests:** 100% pass rate for `shadow_mode.py` (verified via pytest).
- **Recall Precision:** Target $\\ge 95\\%$. Observed mean hit rate is stable for baseline queries.
- **Latency (P99):** Target $\\le 200\\text{ms}$. Candidate latency is within acceptable bounds.
- **ACL Security:** Zero leakage detected (`acl_zero_leakage: true`).

## 3. Shadow Mode Analysis
- **Phase:** Phase 1: Silent Mirroring.
- **Evidence Pack:** `shadow_recall.jsonl` successfully records top-k hit rate, latency delta, and ACL status.
- **Activation Gate:** The `_activation_gate` logic correctly classifies records as `GO`, `WATCH`, or `NO_GO` based on the `ShadowModePolicy`.

## 4. Memory Resonance (v0.4) Implementation Plan
The next phase moves from linear vector search to **associative graph-neural retrieval**.

### Technical Roadmap
1. **Graph Schema Definition (Weeks 1-2):**
   - Nodes: `MemoryChunk`, `Entity`, `Concept`, `Timestamp`.
   - Edges: `RELATED_TO`, `CONTRASTS_WITH`, `EVOLVED_FROM`.
2. **Associative Retrieval Algorithm (Weeks 3-5):**
   - **Seed Capture:** Vector search $\\to$ Top 3 seeds.
   - **Graph Walk:** 2-hop neighbor traversal to expand context.
   - **Resonance Weighting:** Apply temporal decay and edge strength.
3. **Dynamic Pruning (Weeks 6-8):**
   - Implement biological-inspired forgetting for unused edges.
4. **Production Integration:**
   - Integrate with existing `AgentMemoryOS` plugins.
   - Verify using a new "Resonance-specific" shadow test suite.

## 5. Conclusion
The infrastructure for verifying v0.4 is ready. We recommend proceeding to **Phase 2: Early Canary** for the shadow mode ramp-up and simultaneously initiating the **Memory Resonance** development according to the spec.
