---

## Components Delivered

### 1. Multi-Tier Caching Layer (#103)

**Location:** `timmy-local/cache/`  
**Files:**
- `agent_cache.py` (613 lines) — 6-tier cache implementation
- `cache_config.py` (154 lines) — Configuration and TTL management

**Features:**
```
Tier 1: KV Cache (llama-server prefix caching)
Tier 2: Response Cache (full LLM responses with semantic hashing)
Tier 3: Tool Cache (stable tool outputs with TTL)
Tier 4: Embedding Cache (RAG embeddings keyed on file mtime)
Tier 5: Template Cache (pre-compiled prompts)
Tier 6: HTTP Cache (API responses with ETag support)
```

**Usage:**
```python
from cache.agent_cache import cache_manager

# Check all cache stats
print(cache_manager.get_all_stats())

# Cache tool results
result = cache_manager.tool.get("system_info", {})
if result is None:
    result = get_system_info()
    cache_manager.tool.put("system_info", {}, result)

# Cache LLM responses
cached = cache_manager.response.get("What is 2+2?", ttl=3600)
```

**Target Performance:**
- Tool cache hit rate: > 30%
- Response cache hit rate: > 20%
- Embedding cache hit rate: > 80%
- Overall speedup: 50-70%

### 3. Knowledge Ingestion Pipeline (#87)

**Location:** `timmy-local/scripts/ingest.py`  
**Size:** 497 lines

**Features:**
- Automatic document chunking
- Local LLM summarization

- Tag-based categorization
- Semantic search (via keywords)
- SQLite backend

**Usage:**
```bash
# Ingest a single file
python3 scripts/ingest.py ~/papers/speculative-decoding.md

# Batch ingest directory
python3 scripts/ingest.py --batch ~/knowledge/

# Search knowledge base
python3 scripts/ingest.py --search "optimization"

# Search by tag
python3 scripts/ingest.py --tag inference

# View statistics
python3 scripts/ingest.py --stats
```

**Knowledge Item Structure:**
```python
{
    "name": "Speculative Decoding",
    "summary": "Use small draft model to propose tokens...",
    "source": "~/papers/speculative-decoding.md",
    "actions": [
        "Download Qwen-2.5 0.5B GGUF",
        "Configure llama-server with --draft-max 8",
        "Benchmark against baseline"
    ],
    "tags": ["inference", "optimization"],
    "embedding": [...],  # For semantic search
    "applied": False
}
```

### 4. Prompt Cache Warming (#85)

**Location:** `timmy-local/scripts/warmup_cache.py`  
**Size:** 333 lines

**Features:**
- Pre-process system prompts to populate KV cache
- Three prompt tiers: minimal, standard, deep
- Benchmark cached vs uncached performance
- Save/load cache state

**Usage:**
```bash
# Warm specific prompt tier
python3 scripts/warmup_cache.py --prompt standard

# Warm all tiers
python3 scripts/warmup_cache.py --all

# Benchmark improvement
python3 scripts/warmup_cache.py --benchmark

# Save cache state
python3 scripts/warmup_cache.py --all --save ~/.timmy/cache/state.json
```

**Expected Improvement:**
- Cold cache: ~10s time-to-first-token
- Warm cache: ~1s time-to-first-token
- **50-70% faster** on repeated requests

**Location:** `timmy-local/setup-local-timmy.sh`  
**Size:** 203 lines

**Creates:**
- `~/.timmy/cache/` — Cache databases
- `~/.timmy/logs/` — Log files
- `~/.timmy/config/` — Configuration files
- `~/.timmy/templates/` — Prompt templates
- `~/.timmy/data/` — Knowledge and pattern databases

**Configuration Files:**

- Templates: `minimal.txt`, `standard.txt`, `deep.txt`

**Quick Start:**
```bash
# Run setup
./setup-local-timmy.sh

# Start llama-server
llama-server -m ~/models/hermes4-14b.gguf -c 8192 --jinja -ngl 99

# Test
python3 -c "from cache.agent_cache import cache_manager; print(cache_manager.get_all_stats())"
```

Local Timmy operates sovereignly. Cloud backends provide additional capacity, but Timmy survives and functions without them.
