The **MemoryManager** has finally evolved into its true sovereign form: **The Brain**.

### 🏛️ The Architecture of the Brain

Here is how your refined `MemoryManager` now functions as the cognitive orchestrator:

#### **1. Cognitive Skimming (`_resolve_keywords`)**

The Brain first performs "skimming" to understand what it needs to remember.

* It prioritizes **High-Signal sensory data** (Tool metadata) before falling back to **LLM-powered technical extraction**. This ensures that if the tool knows what it's looking for, we don't waste LLM tokens.

#### **2. Tiered Retrieval (`get_reasoning_context`)**

This is the assembly line. It requests the three pillars from the Librarian:

* **Facts (Satya)**: The infrastructure truth.
* **Episodes (Leela)**: The historical mission narratives.
* **Beliefs (Dharma)**: Actionable tactical lessons.
* **The Filter**: Crucially, the Brain performs `_filter_actionable_beliefs`. The Librarian provides the books, but the Brain decides which ones are relevant to the agent's current "Muscles" (capabilities).

#### **3. Tactical Assimilation (`assimilate_proposal` & `assimilate_intervention`)**

This is the nervous system in action.

* **Proposal Ingestion**: Standardizes the "Tactical Proposal." It separates the **Law** (Mission DNA) from the **Wisdom** (Reflection), preventing governance from being corrupted by temporary tactical rationale.
* **Intervention Consolidation**: Merges real-world tool results back into the mission's state. It updates the **MacroPlan**, moving the mission forward in time while enriching the **MacroContext** for the next step.

### ⚖️ The Final Clean Posture

| Feature | Old MemoryManager | New MemoryManager (The Brain) |
| --- | --- | --- |
| **Dependencies** | 3 DB Clients + LLM | **Librarian (EpisodicManager)** + LLM |
| **Code Bloat** | High (Duplicate Cypher/Vector logic) | **Low** (Logic is strictly cognitive) |
| **Security** | Direct DB access from high-level logic | **Protected** (DB interaction is abstracted) |
| **Role** | Storage + Retrieval | **Synthesis + Orchestration** |
