## Architecture

### Memory Tiers (3 + KG)

| Tier | What It Stores | How It's Searched | Decay Half-Life |
|------|---------------|-------------------|-----------------|
| **Episodic** | Events, logs, sessions | FTS5 BM25 + LIKE fallback | 7 days |
| **Semantic** | Facts, knowledge, concepts | FTS5 BM25 + LIKE fallback | 90 days |
| **Procedural** | How-to, workflows, skills | FTS5 BM25 + LIKE fallback | 365 days |
| **Knowledge Graph** | Entities + relations + behavioral rules | FTS5 + BFS traversal | None (explicit only) |

### Cortical Regions (8 Executive + 3 Sensory + 1 Consolidation)

#### Executive Layer

| Region | MCP Tool | Function | Real Implementation |
|--------|----------|----------|-------------------|
| **PFC** (Prefrontal) | `cortex_pfc_enhance` | Cognitive scaffolding with strategy injection | ACC-selected strategy protocol injected into enhancement scaffold. 4 modes: base/enhanced/expert/genius. |
| **ACC** (Anterior Cingulate) | `cortex_acc_strategy` | Strategy switching (6 patterns) | Keyword-match detection for chain-of-thought, tree-of-thoughts, reflexion, constitutional, mixture-of-agents, self-rewarding. |
| **BG** (Basal Ganglia) | `cortex_bg_optimize` | Bottleneck detection, habit formation | Flags operations >5s. Tracks procedural memory access frequency. |
| **OFC** (Orbitofrontal) | `cortex_ofc_persona` | Personality adaptation, modulates 4 downstream targets | Sets system prompt, valuation bias, attention bias. Modulates PFC/Thalamus/Limbic/Broca. 4 personas. |
| **Thalamus** | `cortex_thalamus_route` | Attention gating, 6 routing targets | Keyword-based routing. Now also context-aware via `engine_route`. |
| **Limbic** | `engine_limbic_evaluate` | Affective valence (-1 to +1), behavior loop | **Actually changes behavior**: inhibits actions after 3 negative outcomes, reinforces after 3 positive outcomes. |
| **Broca** | `cortex_broca_reformulate` | Output reformulation per persona | Adds persona-specific instruction prefix to output. |
| **Columnar** | `engine_columnar_process` | Ensemble voting with real diversity | 8 columns with 5 different temperatures (0.1-0.9), 5 distinct prompt framings (critical/creative/stepwise/expert/simplify), random 30-50% input subspaces. Confidence-weighted pooling. |

#### Sensory Layer

| Region | MCP Tool | Function | Integration |
|--------|----------|----------|-------------|
| **Optical** | `optical_perceive` | Visual perception (8 modalities) | Browser, screenshots, OCR, PDF, HTML, SVG, design, camera. Extracts entities. |
| **Touch** | `touch_observe_tool` | Tool interaction observation | Every tool call logged → proficiency map. Success rates tracked over time. |
| **Audio-Spatial** | `audio_spatial_hear/locate` | Sound processing + spatial mapping | Speech, music, analysis + filesystem, network, container topology. |

#### Consolidation Layer

| System | MCP Tools | Function | Real Effect |
|--------|-----------|----------|-------------|
| **DMN Dream Engine** | `dream_cycle`, `get_behavioral_rules`, `analyze_behavioral_patterns` | 3-phase consolidation (nap/deep/full) | Recall → analyze → reinforce good → inhibit bad → prune weak |
| **DMN Consolidation** | `engine_consolidate` | System state modification | **Actually changes system**: prunes weak entries, creates associative links across entities, promotes behavioral rules to higher importance, records consolidation events in KG. |
| **Context Pressure** | Built into engine | Auto-summarization at threshold | Tracks token usage against 128K ceiling. Triggers summarization at 70%, critical at 85%. |
| **Tiered Memory** | Built into engine | Hot/warm/cold classification | Composite score from access_count, recency, importance. Exponential decay: `score * 0.95^days`. |

### Engine Tools (Functional, No Labels)

These are the tools that *actually do things* — not renamed features, but real functional systems:

| Tool | What It Actually Does |
|------|----------------------|
| `engine_consolidate` | Prunes weak KG entries, links related entities via `related_to` relations, promotes frequently-accessed behavioral rules. Stores consolidation events. |
| `engine_limbic_evaluate` | Scores outcome -1 to +1. On 3rd negative: creates `inhibit:*` KG entity. On 3rd positive: creates `best-practice:*` KG entity. These entities can be read by the safety pipeline. |
| `engine_route` | Routes input based on live context: recent_failures >3 → ACC for strategy, workload >10 → BG for optimization, creative persona → OFC first. |
| `engine_columnar_process` | 8 columns, each with unique temp (0.1-0.9) + unique prompt framing + random subspace mask (30-50%). Returns confidence-weighted consensus. |
| `engine_oscillation_status` | Real phase tracking with coherence gates. Auto-switches mode (fast/medium/slow) based on workload. Consolidation gate opens when coherence >0.85. |
| `engine_creativity_diverge` | Generates N approaches using diverse thinking styles (engineering, nature, philosophy, design, economics, quantum, craft, systems) pulled from KG domains. |
| `engine_creativity_analog` | Searches known analogy pairs + KG entities for structural cross-domain matches. Falls back to generative KG-based analogies. |

### Domain Knowledge Modules

7 domains auto-seeded on first server start (74 entities, 146 aliases):

```
🌳 Woodworking    → 12 entities: joinery, materials, tools, finishes
🌱 Gardening      → 10 entities: compost, pH, companion planting, permaculture
⚡ Electronics    → 11 entities: Ohm's law, transistors, op-amps, Arduino
💭 Philosophy     → 10 entities: Plato→Nietzsche, Stoicism, Existentialism
📖 Books          → 10 entities: Dune, 1984, Sapiens, Zettelkasten
⚛️ Quantum Sims   → 10 entities: qubits, Shor/Grover, Qiskit, VQE
💰 Macroeconomics → 10 entities: GDP, inflation, Keynesian, Phillips curve
```

### Session Lifecycle (Engram Pattern)

| Tool | Function |
|------|----------|
| `engram_session_start` | Creates session record in KG, retrieves previous session's open_tasks + conventions. |
| `engram_session_end` | Stores completed_tasks, decisions, open_tasks, conventions_established. Links to project entity. |

### Wiki Memory (Structured Markdown)

| Tool | Function |
|------|----------|
| `wiki_read` | Read a Markdown page from `data/wiki/{path}.md` |
| `wiki_write` | Write/update a Markdown page |
| `wiki_search` | Full-text search across all wiki pages |
| `wiki_list` | List all wiki pages |

### Safety Pipeline (ai-memory-core)

| Feature | Function |
|---------|----------|
| **Prompt Injection Detection** | 9 regex patterns: instruction override, role switch, system prompt extraction, base64, jailbreak, etc. With risk scoring. |
| **PII Redaction** | 6 entity types: email, phone, credit card, SSN, IP, API keys. |
| **Provenance** | SHA-256 hashing of data dicts for integrity verification. |
| **Limbic Blocklist** | Verifier checks KG for `inhibit:*` entities before allowing tool calls. |

### Oscillation Scheduler

Real phase tracking (0-2π), not labels:

| Mode | Trigger | Behavior |
|------|---------|----------|
| **Fast** (γ) | workload > 10 | Direct routing, skip deep processing |
| **Medium** (β) | workload 3-10 | Normal cortical cycle |
| **Slow** (θ) | workload < 3 | Full DMN consolidation, phase coherence gated |

Coherence gate: `phase_coherence > 0.85 → gate opens → consolidation runs`. Based on actual sinusoidal phase calculation.
