-Instead of being a simple memory database, memabra acts as a meta-cognitive controller for agents: given a task, it quickly decides whether to answer directly, recall memory, load a skill, or invoke a tool — and continuously improves this judgment based on task outcomes.

+## 🧠 What is memabra?
+
+> *Most agents memorize. memabra **intuits**.*
+
+memabra is a **local-first, observable, trainable, and replayable** control plane for agent memory and action orchestration.
+
+Instead of acting like a dusty filing cabinet, memabra functions as a **meta-cognitive controller**: given any task, it rapidly decides whether to answer directly, recall memory, load a skill, or invoke a tool — then **learns from outcomes** to sharpen those instincts over time.
+
+- 🏠 **Local-first** — no cloud lock-in, your data stays on disk
+- 📊 **Observable** — every decision is tracked, versioned, and inspectable
+- 🎓 **Trainable** — online learning loop improves routing automatically
+- 🔄 **Replayable** — replay trajectories, audit decisions, roll back versions

-## Quick start
-
-### 1. See the available commands
-
+### 1. Peek under the hood
 ```bash
 memabra --help
 ```
 
-### 2. Run a dry-run evaluation

-A safe way to see the full workflow without actually promoting a new router version:
+### 3. Check system pulse
+```bash
+memabra status --format text
+```
+
+### 4. Inspect your router lineage
+```bash
+memabra version list --format text
+```
+
+### 5. Time-travel (rollback)
+```bash
+memabra version rollback <version-id> --format text

+## 🎮 CLI Commands
+
+| Command | Description |
+|---------|-------------|
+| `memabra run` | 🚀 Execute the online learning workflow |
+| `memabra status` | 💓 Show current system health & metrics |
+| `memabra version list` | 📜 List all saved router versions |
+| `memabra version rollback <id>` | ⏪ Roll back to a specific version |
+
+---
+
+## 🖨️ Operator-Friendly Output
+
+By default, memabra speaks JSON. For humans, add `--format text`:
 
 ```bash
 memabra run --dry-run --format text
 ```
 
-### 3. Check system status
+Sample output:
 
-```bash
-memabra status --format text
+```

-### 4. List saved router versions
+✅ **Normalized booleans** (`yes/no/none`)  
+✅ **Fixed-precision metrics** for easy comparison  
+✅ **Sectioned layout** — Summary → Baseline → Challenger → Deltas → Decision
 
-```bash
-memabra version list --format text

-### 5. Roll back to a previous version
-
-```bash
-memabra version rollback <version-id> --format text

-| Command | Description |
-|---------|-------------|
-| `memabra run` | Run the online learning workflow |

-## Text output format
-
-By default, memabra prints JSON. For operator-friendly summaries, add `--format text`:
-
-- **Status** — current version, trajectory/report counts, latest report timing and promotion outcome.
-- **Version list** — total count, current active version highlighted.
-- **Workflow** — grouped into Summary, Baseline, Challenger, Deltas, and Decision sections with normalized `yes/no` flags and fixed-precision metrics.
