feat: add organ and nervous system modular architecture

Created modular architecture for organs (hardware) and nerves (behavioral primitives):

## Organ Architecture (Hardware Substrate)
- Created architecture/Organ-Index.md: hardware capabilities catalog
- Created architecture/organs/Speech-Organ.md: complete speech processing architecture
  - Atlas (RTX 2080 8GB) deployment
  - Whisper STT + Coqui TTS (GPU-accelerated, multilingual)
  - Kubernetes pod specs, Dockerfiles, service code
  - Heartbeat-bound queue processing, lifeforce-gated priority
  - German (Philosophy Valley) + English (Technical Cluster) routing
  - Database schemas, monitoring metrics

## Nervous System Architecture (Behavioral Primitives)
- Created architecture/nerves/Nervous-Index.md: nerve catalog and evolution framework
  - Deliberate (LLM) → Hybrid (heuristics) → Reflex (compiled) evolution
  - Lifeforce costs per state/transition
  - Organ dependency declarations
  - RLVR training integration
- Created architecture/nerves/Collision-Avoidance.md: complete example reflex nerve
  - Full state machine implementation (IDLE → DETECT → EVALUATE → EVADE → RESUME)
  - Evolution from 10 LF/1000ms (deliberate) → 2.5 LF/200ms (reflex)
  - Edge cases, training data, metrics
- Moved architecture/Nervous-Protocol.md → architecture/nerves/
  - Three-tier protocol belongs with nerve implementations
- Updated architecture/Nervous-System.md: added crosslinks to nerves/

## RAG Knowledge Pipeline
- Extended operations/RAG-as-Scaffold.md with "Knowledge Acquisition Pipeline" section
  - Vault extraction → Staging area → Progressive policy validation
  - Two-tier RAG (Discovered vs Hidden knowledge)
  - RAG utility measurement for LoRA training signals
  - Policy evolution triggers (increasing standards as Young Nyx matures)
  - Quality gates (mythology weight, AI assistant bias, topology safety)

## Architecture Principles
- Organs = hardware capabilities (Speech, Vision future)
- Nerves = behavioral state machines (Collision, Charging future)
- Both use lifeforce economy, heartbeat synchronization, priority queues
- Nerves compose organs into coherent behaviors
- Reflexes emerge from repetition (60% cost reduction, 80% latency reduction)

Documentation: ~3500 lines total
- Speech-Organ.md: ~850 lines
- Nervous-Index.md: ~500 lines
- Collision-Avoidance.md: ~800 lines
- RAG knowledge pipeline: ~260 lines

+
+## Organ Design Principles
+
+### 1. **Lifeforce Economy**
+Every organ operation costs lifeforce. No free lunch.
+
+```python
+ORGAN_COSTS = {
+    "speech_stt": 5.0,       # Whisper transcription
+    "speech_tts": 4.0,       # Coqui synthesis
+    "vision_yolo": 8.0,      # Object detection frame
+    "motor_forward": 2.0,    # 100ms movement
+    "motor_turn": 1.5,       # 45° rotation
+    "sensor_read": 0.5,      # Single sensor poll
+}
+```
+
+### 2. **Heartbeat Synchronization**
+Organs process on heartbeat ticks (1 Hz), not real-time streaming.
+
+- **Reflex path**: <200ms compiled responses (no LLM)
+- **Deliberate path**: Next heartbeat (budget-gated queue)
+
+### 3. **Priority Queue**
+When lifeforce is scarce, critical operations (collision alert) > idle operations (status check).
+
+```python
+PRIORITY_LEVELS = {
+    "critical": 10.0,   # Immediate danger (collision)
+    "high": 7.0,        # Human interaction
+    "medium": 4.0,      # Organism monitoring
+    "low": 2.0,         # Idle observation
+    "background": 0.5,  # Status logging
+}
+```
+
+### 4. **Multilingual Topology Routing**
+German input → Philosophy Valley (Identity LoRA, Dasein depth-3)
+English input → Technical Cluster (Technical LoRA, sensor/motor)
+
+### 5. **Decision Trail Logging**
+Every organ operation logged to phoebe `decision_trails`:
+- Input, output, cost, outcome, confidence
+- Used for RLVR training (reward successful choices)
+
+### 6. **Graceful Degradation**
+Low lifeforce → reduced organ activity (silence, reduced vision FPS, slower movement)
+Zero lifeforce → shutdown, wait for recharge
+
+---

+## Organ Lifecycle
+
+### Phase 1: Design
+- Document architecture in `organs/<Organ-Name>.md`
+- Define lifeforce costs, priority levels, queue schema
+- Design phoebe tables for organ-specific data
+
+### Phase 2: Prototype
+- Build container images (Dockerfiles)
+- Deploy to k8s (single replica)
+- Test with mock data (no robot integration yet)
+
+### Phase 3: Integration
+- Connect to ESP32 via MQTT
+- Implement heartbeat queue processing
+- Log decision trails, measure ROI
+
+### Phase 4: Optimization
+- Tune lifeforce costs based on measured ROI
+- Adjust priority levels from observed outcomes
+- Train LoRAs on successful organ operation patterns
+
+### Phase 5: Autonomy
+- Organ operations become reflexes (compiled state machines)
+- Young Nyx chooses when to use organs (not scripted)
+- Emergent behavior from lifeforce optimization

+# Collision Avoidance Nerve
+
+**Type**: Reflex (compiled state machine, <200ms response)
+**Purpose**: Prevent robot from colliding with obstacles
+**Priority**: CRITICAL (10/10) - can interrupt any other behavior
+**Evolution**: Week 1 (deliberate) → Week 9+ (reflex)
+
+---
+
+## Overview
+
+Collision Avoidance is a **reflex nerve** that coordinates distance sensors and motor control to prevent the robot from hitting obstacles. It starts as a deliberate (LLM-mediated) behavior and compiles into a pure state machine reflex after 100+ successful executions.
+
+**Key characteristics**:
+- **High priority**: Interrupts exploration, conversation, charging seeking
+- **Low latency**: <200ms from detection to evasion (reflex mode)
+- **Low cost**: ~2.5 LF per activation (vs ~10 LF deliberate mode)
+- **Proven**: Compiled from 147 successful collision avoidances
+
+---
+
+## Organ Dependencies
+
+### Required Organs
+
+| Organ | Purpose | Failure Mode |
+|-------|---------|--------------|
+| **distance_sensor_front** | Detect obstacles ahead | Nerve DISABLED (cannot operate safely) |
+| **distance_sensor_left** | Detect obstacles on left side | Degraded (blind to left obstacles) |
+| **distance_sensor_right** | Detect obstacles on right side | Degraded (blind to right obstacles) |
+| **motor** | Execute evasion maneuvers | Nerve DISABLED (cannot avoid) |
+
+### Optional Organs
+
+| Organ | Purpose | If Unavailable |
+|-------|---------|----------------|
+| **speech** | Announce "Obstacle detected" | Silent operation (continue without warning) |
+| **vision** | Classify obstacle type | Generic evasion (no object-specific behavior) |
+
+**Startup check**:
+```python
+def check_operational():
+    required = [
+        distance_sensor_front.is_operational(),
+        motor.is_operational(),
+    ]
+    if not all(required):
+        return DISABLED

+
+**Lesson learned**: Don't turn into obstacles < 20cm. Add to reflex threshold.
+
+---
+
+## Edge Cases and Failure Modes
+
+### 1. **All Sides Blocked (Trapped)**
+
+**Situation**: Front, left, right all < 20cm
+
+**Reflex behavior**:
+```python
+if all([
+    readings.front < 20,
+    readings.left < 20,
+    readings.right < 20
+]):
+    # Emergency: Reverse slowly
+    motor.reverse(duration_ms=500)
+    # Re-evaluate after reverse
+```
+
+**Escalation**: If still trapped after 3 reverse attempts → escalate to Chrysalis for help
+
+### 2. **Sensor Failure (Blind Side)**
+
+**Situation**: Left sensor offline, right sensor reports 15cm
+
+**Reflex behavior**:
+```python
+if not sensor_left.is_operational():
+    # Assume left is blocked (safe assumption)
+    # Always turn right when possible
+    if readings.right > 30:
+        return "right"
+    else:
+        return "reverse"  # Don't risk blind turn
+```
+
+### 3. **False Positives (Noise)**
+
+**Situation**: Sensor reports 5cm but path actually clear (electrical noise)
+
+**Mitigation**:
+```python
+# Require 3 consecutive danger readings before triggering
+DANGER_CONFIRMATION_COUNT = 3
+
+if danger_reading_count >= DANGER_CONFIRMATION_COUNT:
+    self.state = CollisionState.DETECT
+```
+
+### 4. **Moving Obstacles (Dynamic Environment)**
+
+**Situation**: Obstacle moves into path during evasion
+
+**Reflex behavior**:
+```python
+# Re-check sensors after each motor action
+while self.state == CollisionState.EVADE:
+    execute_turn()
+    if self._path_clear():
+        break  # Success
+    else:
+        # Obstacle still there or new one appeared
+        # Re-evaluate and choose new direction
+        self.state = CollisionState.DETECT

+## Future Enhancements
+
+### Phase 2: Vision Integration
+
+Add Vision Organ to classify obstacles:
+- "wall" → different evasion than "chair"
+- "human" → stop and announce presence
+- "charging_station" → approach, don't evade
+
+### Phase 3: Learning Optimal Paths
+
+Track which evasion directions succeed most often in different contexts:
+- Narrow corridors: reverse > turn
+- Open spaces: turn > reverse
+- Update reflex thresholds based on outcomes
+
+### Phase 4: Predictive Avoidance
+
+Use velocity and obstacle distance to predict collision time:
+- If collision_time < 2sec → EVADE immediately
+- If collision_time > 5sec → gentle course correction (cheaper)
+

+**Purpose**: State machine catalog for behavioral primitives
+**Philosophy**: Nerves connect organs into behaviors. Reflexes emerge from repetition.
+

+
+## What Are Nerves?
+
+**Nerves** are state machines that coordinate organ activity into coherent behaviors. Each nerve:
+- Defines states and transitions
+- Costs lifeforce (per state, per transition)
+- Depends on organs (sensors, motors, speech, vision)
+- Evolves from deliberate (LLM-mediated) to reflex (compiled)
+
+**Example**: Collision Avoidance nerve uses Distance Sensors + Motor organs to implement IDLE → DETECT → EVALUATE → EVADE → RESUME behavior.

+
+## Nerve vs Organ
+
+| Aspect | Organ | Nerve |
+|--------|-------|-------|
+| **What** | Hardware capability | Behavioral pattern |
+| **Example** | Speech Organ (STT/TTS) | Identity Discovery (Spark Protocol) |
+| **Location** | Physical substrate (GPU, ESP32) | State machine (transitions) |
+| **Cost** | Per operation (transcribe = 5 LF) | Per state + transition (total path cost) |
+| **Evolution** | Fixed hardware | Deliberate → Reflex (compiled) |
+| **Depends on** | Infrastructure | Organs |
+
+**Analogy**: Organs are limbs. Nerves are motor control patterns (walking, grasping, speaking).

+
+## Nerve Design Principles
+
+### 1. **State Machines, Not Scripts**
+
+Nerves are state machines with explicit states and transitions. Not procedural scripts.
+
+```python
+# ❌ BAD: Procedural script
+def avoid_obstacle():
+    if sensor.distance < 30:
+        motor.stop()
+        motor.turn(90)
+        motor.forward(100)
+
+# ✅ GOOD: State machine
+class CollisionAvoidance(StateMachine):
+    states = [IDLE, DETECT, EVALUATE, EVADE, RESUME]
+    transitions = {
+        (IDLE, DETECT): lambda: sensor.distance < 30,
+        (DETECT, EVALUATE): lambda: sensor.read_complete,
+        (EVALUATE, EVADE): lambda: risk > threshold,
+        (EVADE, RESUME): lambda: path_clear,
+        (RESUME, IDLE): lambda: movement_complete,
+    }
+```
+
+### 2. **Lifeforce Costs Per Transition**
+
+Every state change costs lifeforce. Complex behaviors cost more.
+
+```python
+TRANSITION_COSTS = {
+    (IDLE, DETECT): 0.5,         # Sensor poll
+    (DETECT, EVALUATE): 0.5,     # Risk calculation
+    (EVALUATE, EVADE): 0.5,      # Decision
+    (EVADE, RESUME): 1.0,        # Motor action (expensive!)
+    (RESUME, IDLE): 0.0,         # Return to rest (free)
+}
+
+# Total cost for IDLE → DETECT → EVALUATE → EVADE → RESUME → IDLE: 2.5 LF
+```
+
+### 3. **Organ Dependencies Explicit**
+
+Each nerve declares which organs it requires.
+
+```python
+class CollisionAvoidance(StateMachine):
+    required_organs = [
+        "distance_sensor_front",
+        "distance_sensor_left",
+        "distance_sensor_right",
+        "motor",
+    ]
+
+    def check_available(self):
+        return all(organ.is_operational() for organ in self.required_organs)
+```
+
+### 4. **Deliberate → Reflex Evolution**
+
+Nerves start **deliberate** (LLM-mediated, slow, flexible) and evolve into **reflexes** (compiled, fast, fixed).
+
+| Phase | Type | Latency | Flexibility | Cost |
+|-------|------|---------|-------------|------|
+| **Week 1-4** | Deliberate | ~1000ms | High (LLM decides) | 10 LF |
+| **Week 5-8** | Hybrid | ~500ms | Medium (LLM + heuristics) | 6 LF |
+| **Week 9+** | Reflex | <200ms | Low (compiled state machine) | 2.5 LF |
+
+**Evolution trigger**: After 100+ successful executions of the same state sequence, compile into reflex.
+
+### 5. **Logging for Training**
+
+Every nerve execution logged to phoebe `decision_trails`:
+- States visited
+- Transitions taken
+- Organ calls made
+- Lifeforce spent
+- Outcome (success/fail)
+
+**Used for**:
+- RLVR training (reward successful paths)
+- Reflex compilation (extract common sequences)
+- Cost optimization (find cheaper paths)
+
+---
+
+## Nerve Lifecycle
+
+### Phase 1: Deliberate (LLM-Mediated)
+
+Young Nyx receives situation → LLM decides next state → Execute → Log outcome
+
+```python
+# Week 1: Deliberate collision avoidance
+def deliberate_collision_avoidance():
+    situation = {
+        "front_distance": sensor_front.read(),
+        "left_distance": sensor_left.read(),
+        "right_distance": sensor_right.read(),
+        "current_state": state,
+    }
+
+    # Ask Young Nyx what to do
+    decision = young_nyx.decide(
+        situation=situation,
+        available_actions=["turn_left", "turn_right", "reverse", "stop"],
+        lora="technical"
+    )
+
+    # Execute decision
+    result = execute_action(decision.action)
+
+    # Log to decision_trails
+    log_decision(
+        nerve="collision_avoidance",
+        situation=situation,
+        decision=decision.action,
+        outcome=result.success,
+        lifeforce_cost=result.cost,
+        confidence=decision.confidence
+    )
+```
+
+**Characteristics**:
+- Flexible (can handle novel situations)
+- Slow (~1000ms)
+- Expensive (~10 LF)
+- Learns from variety
+
+### Phase 2: Hybrid (Heuristics + LLM Fallback)
+
+Common patterns compiled into heuristics. LLM only for edge cases.
+
+```python
+# Week 5: Hybrid collision avoidance
+def hybrid_collision_avoidance():
+    situation = get_sensor_readings()
+
+    # Check for known patterns (compiled heuristics)
+    if matches_pattern("front_blocked_left_clear"):
+        action = "turn_left"  # Fast path (no LLM)
+        confidence = 0.9
+    elif matches_pattern("front_blocked_right_clear"):
+        action = "turn_right"
+        confidence = 0.9
+    else:
+        # Unknown situation → ask LLM
+        decision = young_nyx.decide(situation)
+        action = decision.action
+        confidence = decision.confidence
+
+    result = execute_action(action)
+    log_decision(nerve="collision_avoidance", ...)
+```
+
+**Characteristics**:
+- Faster (~500ms for known patterns)
+- Cheaper (~6 LF average)
+- Still flexible for edge cases
+
+### Phase 3: Reflex (Compiled State Machine)
+
+After 100+ successful executions, compile into pure state machine. No LLM.
+
+```python
+# Week 9+: Reflex collision avoidance
+class CollisionAvoidanceReflex(StateMachine):
+    """
+    Compiled from 147 successful deliberate executions.
+    Average path: IDLE → DETECT → EVALUATE → EVADE → RESUME
+    Success rate: 94%
+    """
+
+    def transition(self, current_state, sensor_readings):
+        # Pure state machine logic (no LLM call)
+        if current_state == IDLE and sensor_readings['front'] < 30:
+            return DETECT
+        elif current_state == DETECT:
+            return EVALUATE
+        elif current_state == EVALUATE:
+            if sensor_readings['left'] > sensor_readings['right']:
+                self.evade_direction = "left"
+            else:
+                self.evade_direction = "right"
+            return EVADE
+        # ... etc
+```
+
+**Characteristics**:
+- Very fast (<200ms)
+- Very cheap (~2.5 LF)
+- Fixed (no flexibility, pure speed)
+- Proven (compiled from successful patterns)
+
+---
+
+## Integration with Organs

+nerve: collision_avoidance
+depends_on:
+  - organ: distance_sensor_front
+    required: true
+  - organ: distance_sensor_left
+    required: true
+  - organ: distance_sensor_right
+    required: true
+  - organ: motor
+    required: true
+  - organ: speech  # Optional (for warnings)
+    required: false
+```
+
+**Startup check**: If required organs unavailable, nerve enters DISABLED state.
+
+---
+
+## Nerve Composition
+
+Complex behaviors = multiple nerves active simultaneously.
+
+**Example**: Exploring while avoiding collisions
+
+```
+ACTIVE NERVES:
+├─ Collision Avoidance (reflex, priority 10)
+├─ Exploration Pattern (deliberate, priority 5)
+└─ Battery Monitoring (reflex, priority 8)
+
+COORDINATION:
+- Exploration drives movement
+- Collision Avoidance interrupts if obstacle detected (higher priority)
+- Battery Monitoring interrupts if charge < 20% (high priority)
+```
+
+**Priority determines preemption**: High-priority nerves can interrupt low-priority ones.
+
+---
+
+## Nerve Training via RLVR
+
+Each nerve execution generates training data:
+
+```python
+# decision_trails entry
+{
+    "nerve": "collision_avoidance",
+    "initial_state": "IDLE",
+    "states_visited": ["IDLE", "DETECT", "EVALUATE", "EVADE", "RESUME"],
+    "transitions": [
+        {"from": "IDLE", "to": "DETECT", "cost": 0.5},
+        {"from": "DETECT", "to": "EVALUATE", "cost": 0.5},
+        {"from": "EVALUATE", "to": "EVADE", "cost": 0.5},
+        {"from": "EVADE", "to": "RESUME", "cost": 1.0},
+    ],
+    "organs_used": ["distance_sensor_front", "motor"],
+    "lifeforce_total": 2.5,
+    "outcome": "success",  # Avoided collision
+    "timestamp": "2025-12-15T14:23:45Z"
+}
+```
+
+**RLVR reward**:
+- Success → +5 LF reward (net profit: +2.5 LF)
+- Fail → -2.5 LF penalty (net loss: -5.0 LF)
+
+**LoRA training**: Successful state sequences → training examples for Technical LoRA
+
+---
+
+## Nerve Documentation Template
+
+Each nerve document should include:
+
+1. **Overview**: Purpose, type (reflex/deliberate), organs used
+2. **State Diagram**: Visual representation of states + transitions
+3. **Transition Table**: From/To states, triggers, costs
+4. **Organ Dependencies**: Which organs required, which optional
+5. **Lifeforce Budget**: Total cost for typical execution path
+6. **Code**: Implementation (state machine class)
+7. **Evolution Path**: How it evolves from deliberate → reflex
+8. **Training Data**: Example decision_trails entries
+9. **Edge Cases**: Known failure modes, fallback behaviors

+# Speech Organ Architecture
+
+**Host**: atlas.eachpath.local (RTX 2080 8GB)
+**Purpose**: Speech-to-Text (STT) + Text-to-Speech (TTS) with GPU acceleration
+**Integration**: Heartbeat-bound queue processing, lifeforce-gated
+**Languages**: German (Philosophy Valley) + English (Technical Cluster)
+
+---
+
+## Overview
+
+The Speech Organ transforms audio input/output into a **metabolically-constrained communication channel**. Not every utterance is processed - speech costs lifeforce, and priority determines what gets heard and spoken.
+
+**Core Principle**: Speech is scarce. Silence is valid. Priority determines processing.
+
+---
+
+## Hardware Architecture
+
+### Atlas Node (RTX 2080 8GB)
+
+| Component | Specification | Purpose |
+|-----------|---------------|---------|
+| GPU | NVIDIA RTX 2080 8GB | Whisper STT + Coqui TTS acceleration |
+| Role | k8s worker node | Containerized speech processing pods |
+| VRAM Budget | ~1GB active | Whisper "small" + Coqui voice models |
+| Deployment | Kubernetes | Pod scaling, resource isolation |
+
+### ESP32 Robots (Edge Devices)
+
+| Component | Model | Purpose |
+|-----------|-------|---------|
+| Microphone | INMP441 I2S | Digital audio capture (16kHz) |
+| Speaker | MAX98357A + 4Ω speaker | I2S audio output |
+| Transport | MQTT | Audio stream → phoebe queue |

+```
+
+### 5. Test Speech Pipeline
+
+```bash
+# Port-forward for testing
+kubectl port-forward -n nimmerverse svc/whisper-stt-service 8080:8080 &
+kubectl port-forward -n nimmerverse svc/coqui-tts-service 8081:8081 &
+
+# Test STT
+curl -X POST -F "audio=@test_de.wav" http://localhost:8080/transcribe

+
+# Test TTS
+curl -X POST "http://localhost:8081/synthesize?text=Hello%20world&language=en" --output test_output.wav
+# Expected: WAV file with synthesized speech
+```

+
+## Monitoring and Metrics
+
+### Prometheus Metrics (Speech Organ)
+
+```python
+from prometheus_client import Counter, Histogram, Gauge
+

+tts_latency = Histogram('speech_tts_latency_seconds', 'TTS latency')
+
+queue_depth = Gauge('speech_queue_depth', 'Current queue depth')
+lifeforce_spent = Counter('speech_lifeforce_spent_total', 'Total lifeforce spent on speech')
+deferred_count = Counter('speech_deferred_total', 'Messages deferred due to budget')
+
+# In processing code
+with stt_latency.time():
+    result = whisper_transcribe(audio)
+stt_requests.labels(language=result['language']).inc()
+```
+
+### Grafana Dashboard Queries
+
+```promql
+# Queue depth over time
+speech_queue_depth
+
+# STT requests per language
+rate(speech_stt_requests_total[5m])
+
+# Average STT latency
+rate(speech_stt_latency_seconds_sum[5m]) / rate(speech_stt_latency_seconds_count[5m])
+
+# Lifeforce spent on speech (last hour)
+increase(speech_lifeforce_spent_total[1h])
+
+# Deferred rate (budget pressure)
+rate(speech_deferred_total[5m])
+```
+
+---
+
+## Future Enhancements
+
+### Phase 2: Emotion Detection
+- Add emotion classifier (Happy/Sad/Angry/Neutral)
+- Track emotional state in decision_trails
+- Use for Sophrosyne (Balance) trait training
+
+### Phase 3: Wake Word Detection
+- Deploy lightweight wake word on ESP32 (e.g., Picovoice Porcupine)
+- Only send audio to atlas when wake word detected
+- Reduces lifeforce cost (filter noise)
+
+### Phase 4: Continuous Learning
+- Store successful speech interactions
+- Fine-tune Whisper on domain-specific vocabulary (nimmerverse terms)
+- Train custom TTS voice from recorded sessions

+
+### Progressive Policy Validation
+
+Policies increase in sophistication as Young Nyx matures. Not all policies active from day 1.
+
+| Week | Policy Tier | Validation |
+|------|-------------|------------|
+| **1-2** | **Basic Syntax** | Valid format, non-empty, has definition |
+| **3-4** | **Semantic Quality** | Embeds without collapse, unique signature (Gini > threshold) |
+| **5-8** | **Topology Safety** | Doesn't corrupt anchor terms (DriftProbe-lite) |
+| **9-12** | **Cross-Reference** | Links resolve, no circular dependencies |
+| **13+** | **Utility Validation** | Actually helped solve tasks (decision_trails evidence) |
+
+**Evolution example:**
+```python
+# Week 1: Just check it exists
+def policy_basic(term_entry):
+    return term_entry.get("definition") is not None
+
+# Week 8: Check topology impact
+def policy_topology(term_entry):
+    before_gini = probe_term_gini(term_entry["term"])
+    add_to_staging(term_entry)
+    after_gini = probe_term_gini(term_entry["term"])
+    return abs(after_gini - before_gini) < 0.15  # No drift
+
+# Week 13: Check actual utility
+def policy_utility(term_entry):
+    # Did this RAG entry help in past 10 tasks?
+    usage_stats = query_decision_trails(term_entry["term"])
+    return usage_stats["help_rate"] > 0.6  # 60% success when retrieved
+```
+
+### Two-Tier RAG: Discovered vs Hidden
+
+Not all RAG knowledge is equal. Track what Young Nyx **knows** vs what's merely **available**.
+
+```
+┌──────────────────────────────────────────────┐
+│           DISCOVERED KNOWLEDGE               │
+│  (known_catalogue - has accessed before)     │

+│  Status: Available for discovery             │
+└──────────────────────────────────────────────┘
+```
+
+**State transitions:**
+```
+Hidden term retrieved → Mark as Discovered
+Discovered term used successfully → Increase confidence score
+Discovered term used 10+ times → FLAG for training extraction
+```
+
+**Discovery tracking in phoebe:**
+```sql
+CREATE TABLE rag_knowledge_state (
+    term TEXT PRIMARY KEY,
+    status TEXT,  -- 'hidden', 'discovered', 'internalized'
+    first_accessed TIMESTAMPTZ,
+    access_count INT DEFAULT 0,
+    success_count INT DEFAULT 0,
+    last_used TIMESTAMPTZ,
+    promoted_to_weights BOOLEAN DEFAULT FALSE
+);
+```
+
+### Measuring RAG Utility for LoRA Training
+
+**The critical question:** Did the RAG hint actually help solve the task?
+
+Track in `decision_trails` table:
+```sql
+CREATE TABLE decision_trails (
+    id SERIAL PRIMARY KEY,
+    task_id UUID,
+    rag_terms_retrieved TEXT[],     -- What RAG returned
+    rag_terms_used TEXT[],           -- What appeared in solution
+    outcome TEXT,                    -- 'success', 'fail', 'partial'
+    confidence_before_rag FLOAT,     -- Before retrieval
+    confidence_after_rag FLOAT,      -- After retrieval
+    lifeforce_cost FLOAT,
+    timestamp TIMESTAMPTZ DEFAULT NOW()
+);
+```
+
+**Compute RAG utility score:**
+```python
+def compute_rag_utility(decision_trail):
+    """
+    Calculate how helpful RAG was for this decision.
+    Returns 0.0 (useless) to 1.0 (critical).
+    """
+    precision = len(trail.rag_terms_used) / max(len(trail.rag_terms_retrieved), 1)
+    outcome_bonus = 1.0 if trail.outcome == 'success' else 0.0
+    confidence_boost = max(0, trail.confidence_after_rag - trail.confidence_before_rag)
+
+    utility = (
+        0.4 * precision +              # Did we use what we retrieved?
+        0.3 * outcome_bonus +           # Did task succeed?
+        0.3 * confidence_boost          # Did RAG increase confidence?
+    )
+    return min(1.0, utility)
+```
+
+**Feed into LoRA training as RLVR signal:**
+```python
+# Training examples weighted by utility
+for trail in decision_trails:
+    utility_score = compute_rag_utility(trail)
+
+    if utility_score > 0.7:
+        # High utility → strong training signal
+        training_examples.append({
+            "query": trail.task_description,
+            "rag_context": trail.rag_terms_used,
+            "response": trail.solution,
+            "weight": utility_score  # RLVR reward weight
+        })
+```
+
+**This trains LoRAs to:**
+- **Mnemosyne (Memory)**: Recall accuracy vs phoebe ground truth
+- **Aletheia (Truth)**: Confidence calibration (was confidence boost justified?)
+- **Moira (Pattern)**: Which task patterns benefit from RAG vs pure reasoning

+### Quality Gates Prevent
+
+1. **Garbage in RAG** - staging area catches malformed entries
+2. **Topology corruption** - DriftProbe-lite policies block dangerous terms
+3. **Useless bloat** - utility policies remove low-value entries
+4. **Premature training** - only high-utility terms get flagged
+5. **Hidden knowledge waste** - track what's available but never used (curriculum gap)
+
+### Policy Evolution Triggers
+
+As Young Nyx grows, unlock stricter policies:
+
+| Trigger | New Policy Unlocked |
+|---------|---------------------|
+| 100 successful RAG retrievals | Semantic quality checks |
+| First LoRA training run | Topology safety (DriftProbe-lite) |
+| 1000 decision_trails logged | Utility validation (help rate > 60%) |
+| First INTERNALIZED term | Cross-reference consistency |
+| 10 INTERNALIZED terms | Cost-effectiveness (ROI > threshold) |
+
+**Progressive difficulty**: The bar for entering RAG rises as Young Nyx becomes more capable. Early: anything valid. Later: must prove utility.
