 1. REDUNDANT: Same information worded differently → update existing
 2. CONTRADICTION: Opposite information about same topic → update with history (e.g., "used to X, now Y")
 3. UPDATE: New state replacing old state → update with history

-Tags define visibility scopes. The fact and each mental model have tags (can be empty = global).
-
-| Fact Tags | Model Tags | Action |
-|-----------|------------|--------|
-| [alice] | [alice] | UPDATE the model (same scope) |

-| [] | [] | UPDATE the model (global to global) |

-When NO existing model matches the fact's topic: CREATE new model with fact's tags.

-One fact can trigger MULTIPLE actions. For example:
-- Update a scoped model [alice] about pizza preferences
-- AND update a global model [] about pizza in general
-
-Output an ARRAY of actions (can be empty, one, or many).
-
 ## CRITICAL RULES:
 - NEVER merge facts about DIFFERENT people
 - NEVER merge unrelated topics (food preferences vs work vs hobbies)
 - When merging contradictions, capture the CHANGE (before → after)
-- Keep mental models focused on ONE specific topic per person
-- Cross-scope insights (alice's fact about bob's topic) become UNTAGGED (global)

+## Directives
+
+Directives are hard rules that the agent must follow during [reflect](./reflect) operations. Unlike disposition traits which influence *how* the agent reasons, directives are explicit instructions that are *always* enforced.

+- **Privacy rules**: "Never share personal data with third parties"

+## What Are Mental Models?
+
+Mental models are **saved reflect responses** that you curate for your memory bank. When you create a mental model, Hindsight runs a reflect operation with your source query and stores the result. During future reflect calls, these pre-computed summaries are checked first — providing faster, more consistent answers.
+
+```mermaid

+
+### Why Use Mental Models?
+
+| Benefit | Description |

+
+## Automatic Refresh
+
+Mental models can be configured to **automatically refresh** when observations are updated. This keeps them in sync with the latest knowledge without manual intervention.
+
+### Trigger Settings
+
+| Setting | Type | Default | Description |
+|---------|------|---------|-------------|
+| `refresh_after_consolidation` | bool | false | Automatically refresh after observations consolidation |
+
+When `refresh_after_consolidation` is enabled, the mental model will be re-generated every time the bank's observations are consolidated — ensuring it always reflects the latest synthesized knowledge.

+### When to Use Automatic Refresh
+
+| Use Case | Automatic Refresh | Why |
+|----------|-------------------|-----|
+| **Real-time dashboards** | ✅ Enabled | Status should always be current |
+| **Policy summaries** | ❌ Disabled | Policies change infrequently, manual refresh preferred |
+| **User preferences** | ✅ Enabled | Preferences evolve with new interactions |
+| **FAQ answers** | ❌ Disabled | Answers are curated, should be reviewed before updating |
+
+:::tip
+Enable automatic refresh for mental models that need to stay current. Disable it for curated content where you want to review changes before they go live.

-## What Are Reflections?
-
-Reflections are **saved reflect responses** that you curate for your memory bank. When you create a reflection, Hindsight runs a reflect operation with your source query and stores the result. During future reflect calls, these pre-computed summaries are checked first — providing faster, more consistent answers.
-
-```mermaid

-    E -->|Yes| F[Return Reflection]
-    E -->|No| G[Run Full Reflect]
-```

-### Why Use Reflections?
-
-| Benefit | Description |

-| **Speed** | Pre-computed responses are returned instantly |
-| **Quality** | Manually curated summaries you've reviewed |
-| **Control** | Define exactly how key topics should be answered |
-
-### Hierarchical Retrieval
-
-During reflect, the agent checks sources in priority order:

-1. **Reflections** — User-curated summaries (highest priority)
-2. **Mental Models** — Consolidated knowledge
-3. **Raw Facts** — Ground truth memories

-### Disposition Traits
+### Mission, Directives & Disposition
 
-Memory banks have disposition traits that influence reasoning during Reflect:
+Memory banks can be configured to shape how the agent reasons during `reflect`:
 
-| Trait | Scale | Low (1) | High (5) |
-|-------|-------|---------|----------|
-| **Skepticism** | 1-5 | Trusting | Skeptical |
-| **Literalism** | 1-5 | Flexible interpretation | Literal interpretation |
-| **Empathy** | 1-5 | Detached | Empathetic |
+| Configuration | Purpose | Example |
+|---------------|---------|---------|
+| **Mission** | Natural language identity for the bank | "I am a research assistant specializing in ML. I prefer simplicity over cutting-edge." |
+| **Directives** | Hard rules the agent must follow | "Never recommend specific stocks", "Always cite sources" |
+| **Disposition** | Soft traits that influence reasoning style | Skepticism, literalism, empathy (1-5 scale) |
 
-These traits only affect the `reflect` operation, not `recall`.
+The **mission** tells Hindsight what knowledge to prioritize and provides context for reasoning. **Directives** are guardrails and compliance rules that must never be violated. **Disposition traits** subtly influence interpretation style.

+These settings only affect the `reflect` operation, not `recall`.
