feat: switch default Ollama model to gemma4:e2b

gemma4:e2b has native function calling with dedicated tool tokens,
achieving 100% tool selection accuracy in benchmarks vs 67% for
mistral-nemo-large, with 5-8x faster response times (2-4s vs 15-20s)
and lower VRAM usage (8GB vs 9.2GB).

 ## [Unreleased]
 
+## [2.2.0] - 2026-04-04
+
+### Changed
+
+- **Switch default Ollama model to gemma4:e2b** - Replaces mistral-nemo as the local LLM backend; gemma4:e2b has native function calling support, faster tool calling (2-4s vs 15-20s), better parameter accuracy on word problems, and uses less VRAM (8GB vs 9.2GB)

+### Added
+
+- **Tool calling benchmark script** (`scripts/benchmark_tool_calling.py`) - Compares tool calling accuracy and latency across Ollama models via the Tatlock API
+
+## [2.1.0] - 2026-02-05
+
+### Fixed
+
+- **Streaming SSE compatibility with Open WebUI** - Switch from `exclude_none=True` to `exclude_unset=True` for SSE chunk serialization; `exclude_none` was too aggressive — it stripped `finish_reason: null` from intermediate chunks (which OpenAI includes), while `exclude_unset` correctly omits only fields never passed to the constructor (like `reasoning_content` on content-only chunks) while preserving explicitly-set `finish_reason: null`
+
+### Changed
+
+- **Project structure consolidation** - Moved documentation to `docs/`, consolidated all config into `pyproject.toml`, replaced `wakeup.sh`/`pytest.ini`/`requirements*.txt` with `Makefile` + `pyproject.toml`
+- **CI test gate** - Unit tests now gate release and build jobs in Gitea Actions workflow
+- **Build output organization** - Tool caches in `.cache/`, generated output (coverage, logs) in `build/`
+
+## [2.0.5] - 2026-02-05
+
+### Fixed
+
+- **Streaming JSON compatibility** - Exclude null fields from streaming chunks using `exclude_none=True`; OpenAI's API omits null fields entirely, and including them (e.g., `content: null`, `reasoning_content: null`) caused parsing issues in Open WebUI

+Dependencies are in `pyproject.toml` (`[project.dependencies]` and `[project.optional-dependencies.dev]`).
+
+## Critical Gotchas
+
+**ASGITransport does NOT trigger FastAPI lifespan events.** The session-scoped `_initialize_app` fixture in `tests/conftest.py` calls `initialize_application()` explicitly via `asyncio.run()`. Without this, `check_claude_health()` never runs and `_claude_available` stays `None`, causing all tests to silently fall back to Ollama.
+
+**AsyncIO scope mismatch.** `asyncio_default_fixture_loop_scope = function` is set in `pyproject.toml`. Session-scoped async fixtures cause `ScopeMismatch` errors. The fix is to use a sync fixture with `asyncio.run()` for session-scoped initialization.
+
+**Ollama is unreliable for tool calling.** `mistral-nemo` on Ollama often does mental math instead of calling calculator tools, and frequently gets wrong answers. Claude reliably calls tools. If integration tests give wrong math answers, check which backend is actually being used.
+
+**Integration test timeouts.** Set to 120s to match `OLLAMA_TIMEOUT` config. Ollama on tower-of-joy can be slow, especially on first request.
+
+**`get_benchmark_store` does not exist.** The benchmarking module (`src/core/benchmarks.py`) was never implemented. `scripts/benchmark_analysis.py` also references it and is broken. Do not add mocks for it in tests.
+
+**Steward tests need household registry.** Use `register_household_members()` (sync) in fixtures, not `initialize_application()` (async). The steward extracts capabilities from the registry.

-
----
-
-## Phase 1: Real LLM Integration - PydanticAI + Tools
-
-**Goal**: Connect to actual language models and establish the base plumbing
-
-**Note**: Ollama is an external service dependency (already running separately)
-
-### Deliverables
-
-1. **PydanticAI Integration** ✅
-   - PydanticAI → Ollama connection ✅
-   - Agent creation patterns ✅
-   - Streaming response handling ✅
-   - Error handling and retries ✅
-
-2. **Convert Tatlock Agent** ✅
-   - Convert Tatlock agent from mock to PydanticAI ✅
-   - British butler personality prompt ✅
-   - Research-oriented mindset ✅
-   - Streaming to reasoning output ✅
-   - Tool calling framework setup ✅
-
-3. **Permanent Tools** ✅
-   - Calculator: Safe mathematical expression evaluation ✅
-   - Date/Time toolkit: Current time, relative dates, time differences ✅
-   - Web search: SearXNG integration (external service) ✅
-   - Tool registration with PydanticAI ✅
-
-4. **Testing Infrastructure** ✅
-   - Integration tests with real LLM ✅
-   - Tool functionality tests ✅
-   - Response quality validation ✅
-   - 131 tests, 81.78% coverage ✅
-
-### Success Criteria
-- [x] **PydanticAI agents can call Ollama** (mistral-nemo:latest)
-- [x] **Streaming works end-to-end**
-- [x] **Tool calling framework functional**
-- [x] **Permanent tools working** (calculator, date/time, search)
-- [x] **Tests pass with real LLM**
-- [ ] Can switch models dynamically (e.g., Codestral for code)
-
-### Status
-**✅ MOSTLY COMPLETE** - Tatlock agent functional with permanent tools
-
-### Remaining Work
-- Dynamic model switching for specialized tasks (e.g., Codestral for coding)
-
-### Why First?
-Without real LLM integration, we can't meaningfully implement the Steward/Butler pattern. Everything else depends on having actual AI agents working.
-
----
-
-## Phase 2: Orchestration Layer - The Steward
-
-**Goal**: Implement the first-tier LLM call for tool/agent selection
-
-**Purpose**: The Steward performs crucial preparatory work before Tatlock engages with a request. By analyzing incoming requests and determining which tools, services, and household staff members will be needed, the Steward creates a curated recommendation that streamlines Tatlock's work and prevents cognitive overload.
-
-### Core Architecture
-
-The Steward operates as the first tier in the two-tier request flow:
-
-```
-User Request → Orchestrator → Steward Analysis → Recommendations → Tatlock (with scoped tools/agents)
-```
-
-**Key Principle**: The Steward narrows the scope to only relevant capabilities, making Tatlock's decision-making cleaner and more focused.
-
-### Deliverables
-
-#### 1. Tool & Agent Registry System
-
-**Purpose**: Centralized catalog of all available capabilities for the Steward to recommend
-
-**Implementation Details**:
-- **Registry Module** (`src/core/registry.py`)
-  - Tool registration decorator pattern
-  - Agent registration with capability metadata
-  - Category-based organization (computation, information, automation, communication)
-  - Dynamic tool/agent discovery and loading
-
-- **Tool Metadata Schema**
-  ```python
-  {
-    "name": "calculator",
-    "category": "computation",
-    "description": "Safe mathematical expression evaluation",
-    "capabilities": ["arithmetic", "algebra", "trigonometry"],
-    "cost": "low",  # computational cost indicator
-    "requires_network": false
-  }
-  ```
-
-- **Agent Metadata Schema**
-  ```python
-  {
-    "name": "developer",
-    "role": "The Developer",
-    "category": "technical",
-    "description": "Software development assistance",
-    "domains": ["code_generation", "debugging", "architecture"],
-    "specialized_model": "codestral",  # optional
-    "cost": "high"
-  }
-  ```
-
-- **Registry API**
-  - `get_all_tools()` - List all available tools
-  - `get_all_agents()` - List all expert agents
-  - `get_by_category(category)` - Filter by category
-  - `search_by_capability(query)` - Semantic search (future: vector search)
-
-**Testing**:
-- Unit tests for registration and retrieval
-- Test dynamic loading of new tools/agents
-- Validate metadata schemas
-
-#### 2. Steward PydanticAI Agent
-
-**Purpose**: First-tier LLM that analyzes requests and recommends relevant tools/agents
-
-**Implementation Details**:
-
-- **Agent Module** (`src/agents/steward.py`)
-  ```python
-  from pydantic_ai import Agent, RunContext
-  from pydantic import BaseModel
-
-  class StewardRecommendation(BaseModel):
-      """Structured output from Steward analysis"""
-      recommended_tools: list[str]
-      recommended_agents: list[str]
-      reasoning: str
-      estimated_complexity: str  # "simple", "moderate", "complex"
-      requires_multi_step: bool
-
-  steward = Agent(
-      'ollama:mistral-nemo',  # Same base model as Tatlock
-      result_type=StewardRecommendation,
-      system_prompt="""..."""
-  )
-  ```
-
-- **System Prompt Engineering**
-  - Role: Estate steward responsible for efficient household coordination
-  - Task: Analyze requests to determine needed resources
-  - Output: Structured recommendations with reasoning
-  - Constraints: Be conservative (recommend only truly relevant capabilities)
-  - Context: Full registry of available tools and agents
-
-- **Steward Tools**
-  ```python
-  @steward.tool
-  def get_available_capabilities(ctx: RunContext) -> dict:
-      """Get catalog of all available tools and agents."""
-      return {
-          "tools": registry.get_all_tools(),
-          "agents": registry.get_all_agents()
-      }
-  ```
-
-- **Request Analysis Flow**
-  1. Receive user request
-  2. Query capability registry via tool
-  3. Analyze request for required capabilities
-  4. Generate structured recommendation
-  5. Format as note to Tatlock
-
-**Testing**:
-- Test various request types (simple, complex, multi-domain)
-- Verify recommendations are relevant and not over-inclusive
-- Test structured output parsing
-- Validate reasoning quality
-
-#### 3. Request Preprocessing Pipeline
-
-**Purpose**: Integration layer that routes requests through Steward before Tatlock
-
-**Implementation Details**:
-
-- **Preprocessing Module** (`src/core/preprocessing.py`)
-  ```python
-  async def preprocess_request(user_request: str) -> EnrichedRequest:
-      """
-      1. Call Steward for analysis
-      2. Get recommendations
-      3. Enrich original request
-      4. Return scoped context for Tatlock
-      """
-      # Get Steward analysis
-      steward_result = await steward.run(user_request)
-      recommendations = steward_result.data
-
-      # Create note to Tatlock
-      steward_note = format_steward_note(recommendations)
-
-      # Build scoped tool/agent list
-      scoped_tools = get_scoped_tools(recommendations.recommended_tools)
-      scoped_agents = get_scoped_agents(recommendations.recommended_agents)
-
-      return EnrichedRequest(
-          original_request=user_request,
-          steward_note=steward_note,
-          available_tools=scoped_tools,
-          available_agents=scoped_agents,
-          metadata=recommendations
-      )
-  ```
-
-- **Note Formatting**
-  ```
-  === Internal Note from the Steward ===
-
-  Request Analysis:
-  {steward reasoning}
-
-  Recommended Tools:
-  - calculator: For mathematical computations
-  - web_search: To find current information
-
-  Recommended Household Staff:
-  - The Developer: For code generation assistance
-
-  Estimated Complexity: moderate
-  ===================================
-
-  [Original User Request]
-  ```
-
-- **Orchestrator Integration**
-  - Modify `src/responses/service.py` to call preprocessing
-  - Prepend Steward note to request before sending to Tatlock
-  - Limit Tatlock's tool access to recommended tools only
-  - Stream Steward's reasoning to output
-
-**Testing**:
-- Integration tests for full preprocessing flow
-- Test request enrichment format
-- Verify tool scoping works correctly
-- Test streaming of Steward reasoning
-
-#### 4. Real-Time Transparency
-
-**Purpose**: Stream Steward's analysis to user's reasoning output
-
-**Implementation Details**:
-
-- **Streaming Integration** (`src/responses/streaming.py`)
-  - Add Steward analysis phase to stream
-  - Format as reasoning item
-  - Include recommendation summary
-
-- **Example Output to User**:
-  ```
-  [Reasoning]
-  Consulting the Steward for resource planning...
-
-  The Steward's Analysis:
-  - Request requires mathematical computation
-  - Need to verify current information via web search
-  - May benefit from Developer's code expertise
-
-  Recommended: calculator, web_search, The Developer
-
-  Proceeding with scoped resources...
-  ```
-
-**Testing**:
-- Test streaming of Steward analysis
-- Verify formatting in Open WebUI
-- Test error handling if Steward fails
-
-#### 5. Model Efficiency Optimization
-
-**Purpose**: Ensure the base model stays loaded in VRAM
-
-**Implementation Details**:
-
-- **Shared Model Configuration**
-  - Both Steward and Tatlock use `ollama:mistral-nemo` by default
-  - Sequential calls (Steward → Tatlock) keep model hot
-  - No reload delays between tiers
-
-- **Performance Monitoring**
-  - Log response times for Steward calls
-  - Track total request latency (Steward + Tatlock)
-  - Identify optimization opportunities
-
-**Testing**:
-- Benchmark Steward → Tatlock call latency
-- Verify model stays loaded between calls
-- Test performance under load
-
-### Implementation Strategy
-
-#### Week 1-2: Foundation
-- [ ] Design and implement registry system
-- [ ] Create tool/agent metadata schemas
-- [ ] Build registry API with tests
-- [ ] Migrate existing tools to registry
-
-#### Week 3-4: Steward Agent
-- [ ] Create Steward PydanticAI agent
-- [ ] Engineer system prompt for analysis
-- [ ] Implement structured recommendation output
-- [ ] Add registry query tool
-- [ ] Test with various request types
-
-#### Week 5-6: Integration
-- [ ] Build request preprocessing pipeline
-- [ ] Implement note formatting
-- [ ] Integrate with Orchestrator
-- [ ] Add streaming transparency
-- [ ] Tool scoping for Tatlock
-
-#### Week 7: Testing & Refinement
-- [ ] End-to-end integration tests
-- [ ] Performance optimization
-- [ ] Prompt refinement based on results
-- [ ] Documentation and examples
-
-### Success Criteria
-
-- [x] **Steward analyzes incoming requests** using PydanticAI agent
-- [x] **Produces structured recommendations** (tools, agents, reasoning)
-- [x] **Recommendations formatted as prepended note** to Tatlock
-- [x] **Tool registry is queryable and extensible** via clean API
-- [x] **Steward output visible in reasoning stream** for transparency
-- [x] **Only recommended tools available** to Tatlock (scoped context)
-- [x] **Base model stays loaded** between Steward and Tatlock calls
-- [x] **Recommendations are accurate** (not over/under-inclusive)
-- [x] **Integration tests pass** for full Steward → Tatlock flow
-
-### Status
-**✅ COMPLETE** (v0.2.5)
-
-### Performance Targets
-
-- **Steward Analysis Time**: < 2 seconds for typical requests
-- **Total Added Latency**: < 3 seconds including streaming
-- **Recommendation Accuracy**: > 90% relevance (manual evaluation)
-- **Model Reload Delay**: 0 seconds (model stays hot)
-
-### Risk Mitigation
-
-**Risk**: Steward recommendations too broad (defeats purpose)
-- Mitigation: Conservative prompt engineering, test with diverse requests, iterate
-
-**Risk**: Added latency unacceptable to users
-- Mitigation: Stream Steward reasoning for transparency, optimize prompt, parallel processing where possible
-
-**Risk**: Tool registry becomes unwieldy
-- Mitigation: Good categorization, semantic search (future), regular pruning
-
-**Risk**: Steward and Tatlock models compete for VRAM
-- Mitigation: Use same base model, sequential calls, monitor memory
-
-### Future Enhancements (Post-Phase 2)
-
-- **Semantic Search**: Vector-based capability search instead of metadata lookup
-- **Learning from Usage**: Track which recommendations work well, adjust over time
-- **Confidence Scores**: Steward provides confidence for each recommendation
-- **Request Classification**: Cache classifications for similar requests
-- **Multi-Model Support**: Allow Steward to recommend specialized models for specific tasks
-
-### Estimated Effort
-
-**7-8 weeks** - Core intelligence routing with comprehensive implementation
-
-### Why Second?
-
-The Steward is the foundation of the household architecture. Without it, we'd need to expose all tools/agents to Tatlock, creating cognitive overload and poor decision-making. The Steward enables the focused expertise pattern that makes the whole system work.
-
----
-
-## Phase 3: The Butler - Tatlock Agent
-
-**Goal**: Implement the second-tier coordinator with personality within the existing Orchestrator infrastructure

-- [x] Only recommended tools are available
-- [x] Tatlock coordinates multiple tool calls
-- [x] All actions streamed to reasoning output
-- [x] Responses have consistent personality
-- [x] Synthesizes multi-source results coherently
-

-## Dependencies Between Phases
-
-```
-Phase 1 (Ollama + PydanticAI) ← Foundation for all AI
-    ↓
-Phase 2 (Steward)
-    ↓
-Phase 3 (Butler/Tatlock)
-    ↓
-Phase 4 (Expert Agents) ← Phase 7 (MCP) can enhance

-# Tatlock Enhancement Plan: Bidirectional Claude Integration
-
-## Executive Summary
-
-Implement a **bidirectional architecture** that:
-1. **Superpowers Tatlock** by swapping Ollama→Claude backend (200k context, better reasoning, same butler personality)
-2. **Exposes Tatlock as MCP server** for Claude instances on any device (phone, browser, desktop)
-
-This gives you the flexibility to use whichever AI is best/most accessible at any moment.
-
-## Key Insight: Blanket Backend Swap (Simpler Than Sidecar)
-
-Instead of adding a Claude "Analyst" sidecar agent, **swap the underlying model for ALL agents**:
-
-```
-CURRENT:  TatlockAgent → OpenAIChatModel → OllamaProvider → Ollama (mistral-nemo)
-PROPOSED: TatlockAgent → AnthropicModel → AnthropicProvider → Claude API
-                      ↘ (fallback when offline) → OllamaProvider → Ollama
-```
-
-**Why this works:**
-- PydanticAI natively supports Anthropic via `AnthropicModel` + `AnthropicProvider`
-- The same `TATLOCK_SYSTEM_PROMPT` is passed to Claude - butler personality preserved
-- Claude is **better** at following system prompts than mistral-nemo
-- 200k context for ALL queries, not just "complex" ones
-- Simpler architecture: no routing logic, no sidecar delegation
-
----
-
-## Research Findings
-
-### Industry Best Practices (2025-2026)
-
-**MCP Protocol Updates** ([MCP Spec Updates June 2025](https://auth0.com/blog/mcp-specs-update-all-about-auth/)):
-- Streamable HTTP replaced SSE (March 2025) - better for cloud deployment
-- OAuth 2.0 required for remote servers - MCP servers are OAuth Resource Servers
-- Tool Output Schemas now available - better structured data handling
-- MCP Registry launched (Sept 2025) - community server discovery
-
-**Community Patterns** ([Claude Code Router](https://github.com/musistudio/claude-code-router)):
-- Task-based routing is becoming standard: route simple→local, complex→cloud
-- Translation proxies bridge Anthropic Messages API ↔ OpenAI format
-- Cost savings of up to 98% reported with smart routing
-
-**Home Automation MCP** ([ha-mcp](https://github.com/homeassistant-ai/ha-mcp)):
-- Production-ready MCP servers exist for Home Assistant
-- Support Claude Code, Gemini CLI, Open WebUI, VSCode, Cursor
-- Pattern: expose local tools securely to remote AI clients
-
-**Remote MCP Access** ([mcp-remote](https://www.npmjs.com/package/mcp-remote)):
-- Bridge local MCP servers to Claude Desktop/Browser via proxy
-- Supports authentication headers for security
-- Works with ngrok/Cloudflare Tunnel for HTTPS

-## Cost Analysis
-
-- **Claude API**: $5-30/month (10-50 calls/day, ~2k input + 1k output tokens/call)
-- **MCP via Claude Pro**: Included in subscription
-- **Total**: ~$10-80/month for full bidirectional integration
-
----
-
-## Verification Plan
-
-### Phase 1 Testing
-```bash
-# 1. Run with Claude backend
-ANTHROPIC_API_KEY=your-key docker-compose up -d tatlock
-
-# 2. Verify Claude is being used
-docker logs tatlock 2>&1 | grep -i "anthropic\|claude"
-
-# 3. Test butler personality
-curl -X POST http://tatlock.schweitz.internal:8000/v1/responses \
-  -H "Content-Type: application/json" \
-  -d '{"model": "Tatlock", "input": "Hello, who are you?"}'
-
-# 4. Test offline fallback
-ANTHROPIC_API_KEY="" docker-compose up -d tatlock
-docker logs tatlock 2>&1 | grep -i "ollama\|fallback"
-```
-
-### Phase 2 Testing
-```bash
-# 1. Start MCP server
-docker-compose up -d tatlock-mcp
-
-# 2. Test MCP endpoint
-curl -X POST https://mcp.schweitz.net/tools/list \
-  -H "Authorization: Bearer $MCP_AUTH_TOKEN"
-```
-
----
-
-## Implementation Priority
-
-1. **Phase 1: Backend Swap** (~1 week)
-   - Immediate value: 200k context for ALL queries
-   - Low risk: provider abstraction, graceful offline fallback
-
-2. **Phase 2: MCP Server** (~2-3 weeks)
-   - Enables cross-device access
-   - Bidirectional: Tatlock superpowered by Claude AND accessible to Claude
-
----
-
-## Future Phases (Optional)
-
-- **Phase 3: LiteLLM Gateway** - Unified endpoint for all models, config-driven routing
-- **Phase 4: Multi-Provider** - Add OpenAI, Vertex AI, etc.
-- **Phase 5: Smart Routing** - Context-aware model selection, cost ceiling enforcement
-
----
-
-## Offline Behavior
-
-| Scenario | Behavior |
-|----------|----------|
-| No API key | Use Ollama exclusively |
-| API unreachable | Use Ollama, log warning |
-| API rate limited | Fallback to Ollama |
-
-| Aspect | Claude | Ollama |
-|--------|--------|--------|
-| Context | 200k tokens | ~8k tokens |
-| Latency | 1-3s (network) | 0.5-1s (local) |
-| Personality | Preserved | Preserved |
-| Tools | All work | All work |
-| Cost | API charges | Free |

+```
+Phase 4 (Remaining Agents)
+    ↓
+Phase 5 (Database/Multi-Tenancy) ← Can be deferred
+    ↓
+Phase 7 (MCP) → Phase 8 (Advanced Memory)
+    ↓
+Phase 9 (Extended Staff) → Phase 10 (UX) → Phase 11 (Production)
+```
+
+**Can Be Deferred**: Phase 5 until you need persistence
+**Parallel Opportunities**: Phases 7 and 8 can overlap; 9 and 10 ongoing
+
+---
+
+## Next Steps
+
+1. Implement The Developer agent for code assistance
+2. Add Home Assistant integration for The Housekeeper

+"""
+Benchmark tool calling across different Ollama models via Tatlock API.
+
+Sends test prompts through the full Tatlock pipeline (Steward -> Orchestration
+-> Synthesis) and records tool selection accuracy, latency, and response quality.
+
+Between models, swaps OLLAMA_DEFAULT_MODEL in .env and waits for uvicorn
+auto-reload. Requires the server to be running via ./wakeup.sh.
+
+Usage:
+    .venv/bin/python scripts/benchmark_tool_calling.py
+    .venv/bin/python scripts/benchmark_tool_calling.py --models "gemma4:e4b,gemma4:e2b"
