chore: release v2.4.2

Fixes the v2.4.1 crash-loop: fresh image builds resolved
opentelemetry-api 1.44.0, which removed the private _events module
that pydantic-ai 1.27 imports at startup.

 ## [Unreleased]
 
+## [2.4.2] - 2026-07-19
+
+### Fixed
+
+- Container crash-loop on fresh builds: cap `opentelemetry-api` below 1.44,
+  which removed the private `_events` module that pydantic-ai 1.27 imports
+
+## [2.4.1] - 2026-07-19
+
+### Changed
+
+- **Container-name network defaults** - `SEARXNG_HOST`, `LIBRARY_DESK_HOST`, and `CORE_API_HOST` now default to docker container names on the docker-dataplane network (`http://searxng:8080`, `http://library-desk:8089`, `http://core-api:8083`) instead of host `localhost` ports, ahead of the loopback port rebinding; this also fixes `CORE_API_HOST` pointing at port 8090 (the Scheduler's host port) rather than Core-API's 8083. `scripts/test_housekeeper.sh` now reaches Core-API via `localhost:8083` instead of the LAN IP. Local development against host-published ports still works via `.env` overrides
+
+## [2.4.0] - 2026-07-14
+
+### Removed
+
+- **Dead delegation stack** - deleted the duplicate, never-wired coordination layer so exactly ONE delegation implementation remains (`src/agents/delegation.py`): `src/agents/coordination.py` (`CoordinationEngine`, its own `delegate_to_librarian`, `AGENT_EXECUTORS`/`AGENT_STREAM_EXECUTORS`), the broken-by-design `run_librarian_stream` path it used (Ollama streaming + tool call bug), the `stream_delegate_to_*` wrappers with their never-parsed `__DELEGATION_RESULT__` marker, and `HouseholdRegistry.get_streaming_delegation_tools()` (no callers)
+- **Orphaned agent protocol models** - `src/agents/protocol.py` now contains only the live `AgentError`; the coordination wire protocol it carried (`AgentRequest`, `AgentResponse`, `DelegationIntent`, `CoordinationResult`, `DelegationReason`, `TaskComplexity`, `ToolCallRecord`, `AgentTimeoutError`, `AgentUnavailableError`, `DelegationError`) had no importer left outside its own tests after the coordination stack removal
+
+### Added
+
+- **Test-suite tenant guard** - `tests/conftest.py` hard-fails the whole pytest session (exit code 1, zero tests run) if the effective tenant resolves to the production tenant `jpmschweitzer`, mirroring the guard library-desk applies on its side. Suite-level assertions pin that the session runs under `llm_tester` namespaces (Qdrant `memories_llm_tester`, Redis `session:llm_tester:*`), and the e2e isolation constants now derive from the shared `TEST_TENANT`/`PRODUCTION_TENANT` config constants instead of string literals
+- **Explicit tenant on every library-desk request** - the librarian client now resolves and sends the `user` parameter explicitly on every request (library-desk is removing its server-side default; a missing user would 422). The content extraction endpoints now carry the tenant too, `search_web` no longer falls back to a phantom `tatlock-librarian` user, and a client-level assertion rejects an empty/whitespace tenant before any bytes hit the wire. A parametrized sweep pins the wire contract for all 15 tenant-scoped client methods
+- **Tenant isolation guard** - non-production environments (development/testing) now FORCE the effective tenant to the reserved test tenant `llm_tester` (only `llm_tester` itself or a `test_`-prefixed override is accepted), regardless of `DEFAULT_USER` misconfiguration, at both config resolution and request-context resolution (`get_user()`). Startup refuses (clear error) when a non-production environment is explicitly configured with the production tenant `jpmschweitzer`, and one loud startup log line states the effective/forced tenant
+
+- **Conversation context for experts + real-time think messages** - direct delegation (streaming and non-streaming) now passes a trimmed conversation history (last 6 turns) as expert context, so follow-up questions keep their referent; `_stream_direct_delegation` is now an async generator, so butler think messages ("Allow me to consult the archives, sir.") stream BEFORE the research runs instead of after it completes
+- **Bounded retries and connection reuse for library-desk** - GETs and the read-only `POST /query/*` and `POST /rag/search` endpoints retry once (2 attempts, short backoff) on transport errors and retryable 5xx; wiki writes are never retried. The client now honors `LIBRARY_DESK_TIMEOUT` instead of hardcoded 60s/30s, a librarian run holds one shared HTTP connection instead of constructing a client per tool call, and read tools raise `ModelRetry` on transient HTTP errors so the agent's retry budget engages
+- **One librarian timeout budget** - new `LIBRARIAN_TIMEOUT` (default 180s) enforced with `asyncio.wait_for` inside `delegate_to_librarian`, capping the previously uncapped live paths (steward direct delegation and streaming). The Ollama provider's AsyncOpenAI client now carries an explicit `OLLAMA_TIMEOUT` instead of the SDK's ~600s default, and the contradictory unused 60s default in `AgentRequest.timeout_seconds` was removed (None defers to the configured budget)
+- **Search degradation signaling** - The librarian client parses `source_counts` (plus the additive `source_status`/`degraded` fields when a newer library-desk sends them; absence is tolerated), and `hybrid_search` appends a one-line coverage note when a search is degraded or an enabled source leg contributed nothing, so outages are visible to the model and the user. When `source_status` is present it is used exclusively; without it, count-absence is only inferred for the optional legs the request explicitly enabled (web/documents/volatile) - never the always-on vector/graph legs, whose absence from the top-N counts is normal ranking behavior, so healthy searches no longer emit warnings
+
+### Fixed
+
+- **Clearing all wiki-page tags is possible again** - the Ollama-safe empty-list sentinel in `update_wiki_page` means "leave unchanged", which made it impossible to remove all tags; passing exactly `["__CLEAR__"]` now sends an empty tag list to library-desk (documented in the tool docstring for the local model)
+- **Text-delegation fallback pairs results strictly** - the parallel branch now verifies `asyncio.gather` returned one result per parsed delegation (`zip(..., strict=True)`); a count mismatch fails loudly with a curated apology instead of silently attributing outputs to the wrong agent
+- **Ollama-safe librarian tool schemas** - `update_wiki_page` and `smart_create_wiki_page` no longer use `X | None` parameters (Ollama's OpenAI-compatible API mishandles `anyOf[X, null]`); empty-string/empty-list sentinels are translated to `None` inside the tools, matching the biographer pattern. A snapshot test pins every librarian tool schema to contain no nullable `anyOf`
+- **Honest expert failures** - `run_librarian` now raises a structured `AgentError` instead of returning error text as if it were research output, so delegation correctly reports `success=False` and the streaming error branch is reachable. Failures surface to the user as curated butler-toned sentences; exception detail (including internal URLs) stays in the logs only. Librarian tool errors no longer leak `str(e)` into synthesis
+
+- **HybridRAG response mapping** - The librarian client now parses the field names library-desk actually returns (`source_type`/`sources`, `rrf_score`, `context`, per-item `related_dossiers`, synonyms nested in the `keywords` dict); previously every result rendered as "unknown (score: 0.00)". Source icons now key off the per-item `sources` list. Requests no longer send zero limits (the service rejects them with 422); legs are disabled via `enable_*` flags. Pinned by a contract test against a recorded live response (`tests/agents/librarian/fixtures/`)
+
+## [2.3.0] - 2026-07-13
+
+### Changed
+
+- **Local-first backend (claudification rollback)** - Ollama/gemma4 is now the primary backend; Claude remains as fallback. `PREFER_CLOUD_BACKEND` defaults to `false`, Claude is used automatically when the Ollama startup health check fails, and the Steward retries mid-request failures on the other backend in both directions
+- **Default Claude model `claude-sonnet-5`** - `claude-sonnet-4-20250514` was retired by Anthropic on 2026-06-15 and would 404, leaving the fallback dead
+- **Dedicated orchestration prompt** - `orchestrate_tool_calls()` now uses a terse tool-execution prompt (`TATLOCK_ORCHESTRATION_PROMPT`); the butler persona prompt suppressed gemma4 tool calling (the model reasoned about the calculator, then answered from memory with wrong arithmetic). Synthesis keeps the persona prompt, so user-visible voice is unchanged
+
+### Fixed
+
+- **Startup crash with broken anthropic package** - Anthropic SDK imports in the model selector are now lazy, so an incompatible `anthropic` install degrades to Ollama-only operation instead of crashing the app at import time (root cause of the production outage since April)
+- **Claude Sonnet 5 rejects sampling parameters** - removed `temperature` from the Steward's direct Claude call and made the Housekeeper's temperature setting backend-conditional via `get_sampling_settings()`
+- **Pin `anthropic>=0.77,<1.0`** - the April image resolved an anthropic version incompatible with pydantic-ai 1.27
+- **Steward timeout configurable** - new `STEWARD_TIMEOUT` (default 60s) replaces the hardcoded 30s, which gemma4 chronically exceeded (~35s warm analysis), causing every request to fail or fall back
+
+### Added
+
+- **Ollama startup health check** - verifies the server is reachable and `OLLAMA_DEFAULT_MODEL` is pulled; feeds backend resolution and `get_model_info()`
+- **Contract tests** (`tests/contracts/`, `make test-contracts`) - wire-level tests that send the raw requests the code sends to Ollama (native + OpenAI-compat tool calling), Anthropic (including the pinned temperature-rejection contract), Qdrant, SearXNG, library-desk, and Redis; unreachable services skip, wrong response shapes fail
+- **Backend resolution unit tests** (`tests/anthropic/`)
+
+## [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
+
+## [2.0.4] - 2026-02-05
+
+### Fixed
+
+- **Open WebUI streaming compatibility** - Replaced `sse_starlette` `EventSourceResponse` with plain `StreamingResponse` for chat completions; `sse_starlette` added `\r\n` line endings and extra SSE fields that Open WebUI couldn't parse
+
+## [2.0.3] - 2026-02-05
+
+### Fixed
+
+- **Steward analysis leaking into responses** - Removed internal routing analysis (`DELEGATE: tatlock_core...`) from user-visible reasoning in both streaming and non-streaming paths
+
+## [2.0.2] - 2026-02-05
+
+### Fixed
+
+- **tool_choice format incompatibility** - Removed `extra_body` tool_choice hack for Claude backend; PydanticAI handles tool_choice natively for Anthropic, preventing infinite tool call loops
+- **CI trigger** - Changed workflow trigger from `release:published` to `push:tags:v[0-9]*`
+
+## [2.0.1] - 2026-02-05
+
+### Fixed
+
+- **Expert agent registration failure** - `AnthropicModel` does not accept `api_key` directly; now passes it via `AnthropicProvider`
+
+## [2.0.0] - 2026-02-05
+
+### Added
+
+- **Claude backend support (Claudification Phase 1)** - All agents now prefer Claude over Ollama
+  - New `src/anthropic/` module with model selector and health check
+  - `get_model()` factory returns Claude if available, Ollama as fallback
+  - Startup health check caches Claude API availability
+  - Configuration: `ANTHROPIC_API_KEY`, `ANTHROPIC_MODEL`, `PREFER_CLOUD_BACKEND`
+  - 200k token context when using Claude backend
+
+- **Steward dual-backend support** - Direct API calls to Claude or Ollama
+  - `_call_claude()`: Anthropic Messages API path
+  - `_call_ollama()`: Existing Ollama generate API path (preserved)
+  - Automatic fallback: if Claude call fails mid-request, retries with Ollama
+
+- **Claudification project tracking** - `PROJECT_CLAUDIFICATION.md` with Phase 1/2 roadmap
+
+### Changed
+
+- **All PydanticAI agents refactored to use `get_model()`**:
+  - Tatlock (6 instantiation locations)
+  - Librarian
+  - Biographer
+  - Housekeeper
+- **`initialize_application()` is now async** - Supports async Claude health check at startup
+- **Dependencies**: `pydantic-ai-slim[openai,anthropic]` replaces `pydantic-ai-slim[openai]`
+- **Startup logging** now includes backend selection info (claude/ollama)
+- **Agent creation logging** now includes backend and model info
+
+### Removed
+
+- Stale `tests/core/test_benchmarks.py` (benchmark system was removed in v1.10.0)
+
+## [1.11.0] - 2025-12-30
+
+### Added
+
+- **Paperless document integration** - HybridRAG now includes indexed PDFs and scanned documents from Paperless-ngx
+  - New `include_documents` parameter in `hybrid_search` tool

+
+- **Volatile cache integration** - HybridRAG now includes pre-fetched real-time data
+  - New `include_volatile` parameter in `hybrid_search` tool
+  - ⚡ icon for volatile sources in search results
+  - Supports weather, forecast, news, stock, crypto, sun, air_quality namespaces
+  - Librarian prompt updated with volatile cache awareness (user-configured items only)
+
+- **Biographer routing in Steward** - Personal memory queries now correctly route to The Biographer
+  - Added explicit routing rules for "where do I live", "what car do I drive", etc.
+  - Added biographer delegation examples to Steward prompt
+  - Location keywords ("live", "where", "home") now trigger profile pre-fetch
+
+### Changed
+
+- **LibraryDeskClient.hybrid_search** - Now passes full config including `document_limit`, `volatile_limit`, and enable flags
+- **Steward guidelines** - Clarified that research queries about TOPICS go to Librarian, queries about USER go to Biographer
+
+## [1.10.1] - 2025-12-23
+
+### Fixed
+
+- **Tatlock's excessive apologizing** - Strengthened personality prompt to prevent unnecessary apologies after successful Librarian delegations. Added explicit "do NOT apologize" instructions to both system prompt and synthesis prompt.
+
+## [1.10.0] - 2025-12-22
+
+### Added
+

+  - Steward analysis spans in preprocessing
+  - Tatlock orchestrate/synthesize spans
+  - Expert delegation spans (librarian/biographer/housekeeper)

+  - `REDIS_BENCHMARK_DB` config setting
+  - `redis_url` property (kept `redis_memory_url`)
+  - Benchmark recording in Steward service and tool tracking
+
+### Fixed
+
+- **Librarian fabrication prevention** - Added explicit instructions to never invent data when tools fail or sources are unavailable
+
+## [1.9.0] - 2025-12-18
+
+### Changed
+
+- **Housekeeper prompt optimization** - Rewrote system prompt for Mistral-Nemo function calling with negative constraints, step-by-step process, and explicit entity ID format guidance
+- **Housekeeper temperature setting** - Set temperature to 0.1 for deterministic tool calling behavior
+- **Device list room group priority** - Room groups now appear first in `list_devices` output with `[ROOM GROUP]` marker to address positional bias
+- **Tool docstring improvements** - Updated turn_on/turn_off/toggle with explicit `entity_id=` parameter examples
+
+### Added
+
+- **Housekeeper optimization findings** - Added `docs/housekeeper-optimization-findings.md` documenting the experiment journey from 0% to 100% success rate
+- **Housekeeper test script** - Added `scripts/test_housekeeper.sh` for room group detection regression testing
+
+## [1.8.6] - 2025-12-17
+
+### Fixed
+
+- **Housekeeper API paths** - Updated all client endpoints to use `/housekeeping/` prefix to match core-api routes
+- **Housekeeper entity hallucination** - Improved system prompt with critical rule requiring `list_devices()` before any control action to prevent guessing entity IDs
+
+### Added
+
+- **Housekeeping API spec** - Added `docs/housekeeping-api-spec.md` documenting the core-api home automation interface
+
+## [1.8.5] - 2025-12-16
+
+### Fixed
+
+- **Redis benchmark boolean storage** - Convert booleans to strings for Redis `hset` (Redis doesn't accept bool type directly)
+- **Tool tracking capability matching** - `delegate_to_librarian` now correctly recognized as using "librarian" capability when checking Steward recommendations
+- **E2E test fixture scope** - Fixed pytest-asyncio ScopeMismatch error by using `loop_scope="module"` for module-scoped async fixtures
+
+## [1.8.4] - 2025-12-16
+
+### Fixed
+
+- **Remove `<think>` wrappers from think messages** - Messages in `reasoning_content` should be plain text
+- Removed `<think>` wrappers from delegation.py household think messages
+- Removed `<think>` wrappers from orchestration.py status messages
+- Think messages now appear cleanly in Open WebUI's reasoning block
+
+## [1.8.3] - 2025-12-16
+
+### Fixed
+
+- **Open WebUI streaming rendering** - Use `reasoning_content` field for thinking (DeepSeek R1 format) instead of `<think>` tags in `content`
+- Open WebUI now renders thinking as proper collapsible blocks instead of broken HTML
+
+## [1.8.2] - 2025-12-16
+
+### Fixed
+
+- **HybridRAG keywords schema mismatch** - library-desk now returns `keywords` as dict with `core_keywords`, client now handles both formats
+
+## [1.8.1] - 2025-12-16
+
+### Fixed
+
+#### Ollama Message Sanitization
+- **Fixed `invalid message content type: <nil>` error** from Ollama
+- Created custom `TatlockOllamaProvider` that sanitizes messages before sending to Ollama
+- Ollama rejects assistant messages with `content: null` (tool-only messages from PydanticAI)
+- Provider converts `null` content to empty string `""` for compatibility
+- Updated all agents (Librarian, Biographer, Housekeeper, Tatlock) to use sanitized provider
+- Added `src/ollama/provider.py` with reusable provider pattern
+
+#### Streaming Think Message Accumulation
+- **Fixed repeating think messages in frontend** (e.g., 10x "The Librarian has compiled...")
+- Frontend was accumulating `ReasoningSummaryDelta` events expecting concatenation
+- Added `ReasoningSummaryDone()` signal after each think message to indicate completion
+- Each think slug is now treated as a complete message, not a continuation
+
+## [1.8.0] - 2025-12-15
+
+### Fixed
+
+#### Steward Routing for Web Search
+- Updated Steward guidelines to route web searches, weather, news → Librarian with `search_web`
+- Added URL/article reading → Librarian with `read_url` to routing guidelines
+- Added examples showing `search_web` and `read_url` tool usage
+
+#### Librarian Agent Tool Registration
+- Registered `search_web`, `read_url`, `read_urls_batch` tools with the Librarian PydanticAI agent
+- Updated Librarian system prompt with Web Search & Content Extraction section
+- Fixed tool count in agent logger (11 → 14 tools)
+
+#### Query Enrichment Integration
+- Fixed enriched query (with location/timezone context) not being passed to delegations
+- Response service now uses `enriched_query` from Steward recommendation for all delegations
+- Weather queries now automatically include user's stored location
+
+#### Action Type Detection
+- Added "read", "fetch", "url", "http" keywords to RESEARCH action type for Librarian
+- Ensures proper think messages for URL reading tasks
+
+## [1.7.0] - 2025-12-15
+
+### Added
+
+#### Web Search Migration to Librarian
+- **`search_web()`** tool in Librarian for web search via library-desk `/rag/search` endpoint
+- **`read_url()`** tool for single URL content extraction via Trafilatura
+- **`read_urls_batch()`** tool for parallel batch URL extraction (max 20 URLs)
+- `WebSearchResult`, `WebSearchResponse` models in LibraryDeskClient
+- `ContentExtractionResult`, `BatchExtractionResponse` models for content extraction
+- `search_web()`, `extract_content()`, `extract_content_batch()` methods in LibraryDeskClient
+- Comprehensive unit tests for new Librarian tools (`tests/agents/librarian/test_tools.py`)
+
+### Changed
+
+- Librarian capability updated with web search domains: "web", "url", "internet"
+- Tatlock system prompt now delegates web search to Librarian
+- `tatlock_core` capability reduced to computation/datetime only (no longer requires network)
+
+### Removed
+
+- `search_web` function from `src/agents/tatlock_core/tools.py`
+- `web_search_tool` from `tatlock_core_tools` list
+- `search_web` from legacy `src/agents/tools.py`
+- Search tests from `tests/agents/test_tools.py` (moved to Librarian tests)
+
+## [1.6.0] - 2025-12-15
+
+### Added
+
+#### Two-Phase Tatlock Execution
+- **Phase 1: Orchestration** - Executes tool calls and expert delegations, returns structured results
+- **Phase 2: Synthesis** - Synthesizes butler-toned response from gathered results
+- `orchestrate_tool_calls()` method in TatlockAgent for coordination phase
+- `synthesize_from_results()` method in TatlockAgent for synthesis phase
+- Guarantees butler personality in all responses by separating coordination from response generation
+
+#### Automatic Think Slugs
+- **Deterministic butler-perspective messages** during expert delegation (no LLM involved)
+- `ActionType` enum: RETRIEVE, RESEARCH, CREATE, CONTROL, RECORD
+- `HOUSEHOLD_THINK_MESSAGES` mapping with butler-perspective messages for all experts:
+  - Librarian: "Allow me to consult the archives, sir." / "I'm having the Librarian prepare a new entry."
+  - Biographer: "Let me consult the household records." / "I've asked the Biographer to take note, sir."
+  - Housekeeper: "I'm instructing the household staff now, sir." / "Allow me to inquire with the household staff."
+- `_detect_action_type()` function for keyword-based action detection
+- `get_think_message()` helper for retrieving appropriate messages
+- Streaming delegation wrappers: `stream_delegate_to_librarian()`, `stream_delegate_to_biographer()`, `stream_delegate_to_housekeeper()`
+- `STREAMING_DELEGATION_WRAPPERS` mapping in delegation.py
+- `get_streaming_delegation_tools()` method in HouseholdRegistry
+
+#### Steward Query Enrichment
+- **Auto-fill user context** (location, timezone) when not specified in query
+- `_build_enriched_query()` function in steward service
+- Regex word boundary matching for accurate location detection (avoids false positives)
+- `enriched_query` field added to `StewardRecommendation` schema
+- Automatic enrichment for weather queries (location), time queries (timezone), temperature preferences
+
+#### Documentation
+- **ORCHESTRATION_SCENARIOS.md** completely rewritten with:
+  - Mermaid flow diagrams for two-phase execution
+  - 4 new Housekeeper scenarios (light control, device status, parallel delegation)
+  - Biographer memory recording scenario
+  - Complete think slug reference tables
+  - Action type detection tables
+  - Updated architecture mindmap
+- **TESTING_IMPROVEMENTS.md** - LLM testing best practices for future implementation
+
+### Changed
+
+- `create_response_with_steward()` now uses two-phase execution
+- `_direct_delegation()` routes through synthesis phase for consistent butler tone
+- `_execute_single_delegation()` now supports housekeeper
+- Streaming response handler integrated with think slug system
+- All 326 unit tests passing
+
+## [1.5.0] - 2025-12-15
+
+### Added
+
+#### The Housekeeper Agent
+- **New home automation expert agent** following the Librarian pattern
+- `CoreAPIClient` for communicating with core-api service (Home Assistant wrapper)
+- 13 tools for home automation:
+  - Discovery: `list_areas`, `list_devices`, `get_device_state`
+  - Control: `turn_on`, `turn_off`, `toggle`
+  - Scenes: `list_scenes`, `activate_scene`
+  - Scripts: `list_scripts`, `run_script`
+  - Automations: `list_automations`, `toggle_automation`
+  - History: `get_history`
+- PydanticAI agent with system prompt for home automation tasks
+- `HouseholdCapability` registration with domains: lights, switches, automation, home, smart home, scene, script, device, climate, fan, cover, blinds
+- `delegate_to_housekeeper()` delegation wrapper
+- Config settings: `CORE_API_HOST`, `CORE_API_KEY`, `CORE_API_TIMEOUT`
+
+#### Development Port Change
+- **Dev server port changed from 8123 to 8777** to avoid conflict with Home Assistant default port
+- Updated `wakeup.sh`, E2E tests, and documentation
+
+### Changed
+
+- All unit tests pass (421 passed, 5 xfailed)
+- Housekeeper registered on startup alongside Librarian and Biographer
+
+## [1.4.0] - 2025-12-14
+
+### Added
+
+#### Environment-Aware Configuration
+- **Auto-selected logging level**: DEBUG for development, WARNING for production
+- **Auto-selected default user**: `llm_tester` for development (isolated test scope), `jpmschweitzer` for production
+- Properties `effective_log_level` and `effective_default_user` in config
+- User context logging at request entry with INFO level
+
+#### Direct Delegation Bypass
+- **Pure memory/librarian requests bypass Tatlock**: When Steward recommends only biographer/librarian, skip Tatlock LLM call
+- `_direct_delegation()` function for immediate expert agent execution
+- Reduces latency for memory-only requests
+
+#### Text-Based Delegation Fallback
+- **Parse text delegation patterns**: Handle LLM outputs like `[DELEGATE:biographer] task="..."`
+- Multiple pattern support for delegation parsing
+- Sequential and parallel execution with `[PARALLEL]` prefix
+
+#### Comprehensive E2E Test Suite
+- **22 new orchestration tests** in `tests/e2e/test_orchestration_e2e.py`
+- `QdrantVerifier` helper class for data verification
+- `assert_llm_behavior()` for flexible LLM output pattern matching
+- Test classes covering:
+  - Memory storage and recall
+  - Steward delegation
+  - Direct delegation bypass
+  - User context isolation (llm_tester vs production)
+  - Data verification in Qdrant
+  - Integration health checks
+  - Orchestration scenarios (weather, calculator, wiki, multi-expert)
+  - Error handling
+  - Evaluation reports
+- Updated `tests/e2e/README.md` with comprehensive documentation
+
+### Fixed
+
+- **Unit test mocks**: Updated Steward streaming tests to mock `run_with_scoped_tools_stream` (async generator)
+- **Temporal context in tests**: Tests now account for `_inject_temporal_context()` appending timestamps
+- **LLM non-determinism**: Integration tests use `pytest.xfail()` for LLM-dependent assertions
+- **Streaming test timeouts**: Increased timeouts (60-90s) for LLM processing time
+
+### Changed
+
+- All unit tests now pass (380 passed, 5 xfailed for LLM non-determinism)
+- E2E tests use `llm_tester` user for isolation from production data
+
+## [1.3.3] - 2025-12-14
+
+### Fixed
+
+- **Memory**: Fix Qdrant point IDs - use UUID5 instead of arbitrary strings
+
 ## [1.3.2] - 2025-12-14

+
+## Setup & Commands
+
+```bash
+make setup          # Create venv and install all dependencies
+make test           # Unit tests (no external services)
+make test-integration  # Integration tests (needs Claude/Ollama)
+make test-contracts # Wire-level contract tests against live service boundaries
+make run            # Start dev server on port 8777
+make lint           # Ruff linter + formatter check
+make typecheck      # Mypy
+make clean          # Remove caches and build artifacts
+```
+
+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, the Ollama/Claude health checks never run: `_ollama_available` stays `None` (treated as available, so requests go to Ollama) and `_claude_available` stays `None` (treated as unavailable, so the Claude fallback never engages).
+
+**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.
+
+**The butler persona prompt suppresses local-model tool calling.** With `TATLOCK_SYSTEM_PROMPT` attached, gemma4 reasons about calling the calculator, then answers from memory with wrong arithmetic (a different wrong product each run). `orchestrate_tool_calls()` therefore uses the terse `TATLOCK_ORCHESTRATION_PROMPT`; the persona is applied in `synthesize_from_results()`. Do not reattach the persona prompt to a tool-phase agent. `tool_choice: "required"` via extra_body does NOT force Ollama to call tools — it is advisory at best.
+
+**Claude Sonnet 5+ rejects sampling parameters.** `temperature`/`top_p`/`top_k` return a 400. Use `get_sampling_settings()` from the model selector instead of passing `ModelSettings(temperature=...)` directly to agents that can run on the Claude fallback. The contract test suite pins this (`make test-contracts`).
+
+**Integration test timeouts.** Set to 120s to match `OLLAMA_TIMEOUT` config (300s for the pure-Ollama fallback test, which cannot be rescued by Claude). Current GPU-resident numbers (2026-07-14, driver 570, gemma4:e2b at ~100 tok/s): Steward analysis ~6s warm, full Steward → orchestrate → synthesize flow 11–25s, librarian-routed queries ~20-25s. The old "~35s steward / ~2 min flow" figures were measured during the CPU-only era (driver mismatch, 13 tok/s) — do not plan against them. Cold start after 2h idle adds ~8s (`OLLAMA_KEEP_ALIVE=2h`). `STEWARD_TIMEOUT` defaults to 60s.
+
+**`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.

-# Orchestration Scenarios and Tool Flows
-
-This document outlines example scenarios of varying complexity to illustrate the desired orchestration patterns between Tatlock (Butler/Coordinator), expert agents (The Librarian, etc.), and the user.
-
-## Architecture Overview
-
-```
-User Request
-     ↓
-[Steward] → Analyzes request, has visibility into ALL capabilities
-           → Makes routing decision: which experts needed
-           → Passes simplified instruction to Tatlock (not raw tool schemas)
-     ↓
-[Tatlock/Butler] → Coordinator, receives "use Librarian for wiki creation"
-                 → Calls expert agents as tools
-                 → Synthesizes responses into butler-voice answer
-     ↓
-[Expert Agents] → The Librarian, Home Automation, Memory, etc.
-                → Each has their own specialized tools
-                → Return structured results to Tatlock
-     ↓
-[External APIs] → library-desk, home-assistant, user-db, etc.
-```
-
-**Key Principles**:
-
-1. **Steward sees everything** - Has access to all capability descriptions to make informed routing decisions
-2. **Simplified passthrough** - Tatlock receives "delegate to Librarian for research" not 16 tool schemas
-3. **Expert agents are tools** - Tatlock calls `librarian_agent(task)`, not `hybrid_search()` directly
-4. **Each expert owns their tools** - Librarian has wiki tools, Home Automation has device tools
-5. **Results flow up** - Tatlock synthesizes all expert responses into coherent butler answer
-
----
-
-## Scenario 1: Weather Check (Multi-Step with Memory Lookup)
-
-**User**: "What's the weather like?"
-
-### Complexity Analysis
-
-This seemingly simple request requires:
-1. **Location determination** - Where does the user want weather for?
-2. **Memory/database lookup** - Retrieve user's home location or current location
-3. **Weather data fetch** - Search for weather at determined location
-
-### Flow
-
-```
-1. Steward Analysis
-   → Capabilities needed: memory (user context), tatlock_core (web search)
-   → Complexity: moderate
-   → Note: Location must be determined before weather lookup
-
-2. Tatlock Execution - Step 1
-   <think>User asked about weather but didn't specify location.
-   Checking user profile for home location...</think>
-   → Calls: memory_agent(task: "get user home location")
-   → Memory queries user database
-   → Returns: "User home location: Amsterdam, Netherlands"

----
-
-## Response Pattern Guidelines
-
-### Tatlock's Think Updates (Streaming to User)
-
-During multi-step operations, Tatlock should emit `<think>` updates to keep the user informed:
-
-```
-<think>Analyzing your request...</think>
-<think>Searching for deadline information in the wiki...</think>
-<think>Found the deadline - December 15th. Creating reminder...</think>
-<think>Updating the project page with status note...</think>
-<think>All tasks complete. Composing response...</think>
-```
-
-### Tatlock's Final Response Pattern
-
-1. **Acknowledge** - Confirm understanding of the request
-2. **Summarize actions** - What was done, by whom (implicitly)
-3. **Key details** - Important information the user should know
-4. **Proactive offer** - Suggest related actions or follow-ups
-5. **Butler voice** - Formal but warm, with personality
-
-### Expert Agent Response Pattern
-
-1. **Task status** - Completed/Partial/Failed
-2. **Action summary** - What was done
-3. **Key data** - Information Tatlock needs to synthesize
-4. **Metadata** - IDs, counts, timestamps for reference
-5. **Suggestions** - Optional follow-up actions
-
----
-
-## Error Handling Scenarios
-
-### Expert Agent Failure
-
-```
-Tatlock → Librarian: "Create wiki page about quantum computing"
-Librarian → Tatlock: "Error: library-desk API unavailable (connection timeout)"
-
-Tatlock Response:
-"I'm afraid The Librarian is having some difficulty reaching the wiki
-service at the moment, sir. I can attempt a basic web search on quantum
-computing if you'd like, or we can try the wiki operation again in a
-few minutes."
-```
-
-### Partial Completion
-
-```
-User: "Create a reminder and add it to my calendar"
-
-Tatlock → PA: Create reminder
-PA → Tatlock: "Reminder created successfully"
-
-Tatlock → Calendar: Add to calendar
-Calendar → Tatlock: "Error: Calendar sync not configured"
-
-Tatlock Response:
-"I've created the reminder, sir, but I wasn't able to add it to your
-calendar - it appears the calendar integration needs to be configured.
-The reminder will still alert you at the scheduled time. Shall I help
-set up the calendar connection?"
-```
-
----
-
-## Summary: Key Design Principles
-
-1. **Tatlock is the orchestrator** - Never exposes raw tool complexity to users
-2. **Expert agents are tools** - Tatlock calls them, they return structured responses
-3. **Context flows down** - Each expert gets only what they need to complete their task
-4. **Results flow up** - Tatlock synthesizes all responses into coherent butler-voice answer
-5. **Think updates maintain engagement** - User sees progress during complex operations
-6. **Errors are handled gracefully** - Tatlock explains and offers alternatives
-7. **Proactive suggestions** - Tatlock anticipates follow-up needs

+# Claude Integration Plan
+
+## Overview
+
+Tatlock uses a bidirectional Claude architecture:
+- **Scenario A**: Tatlock powered by Claude backend (with Ollama fallback) — **COMPLETE**, then **rolled back to local-first**: Ollama/gemma4 is primary, Claude is retained as fallback (`PREFER_CLOUD_BACKEND=false`)
+- **Scenario B**: Tatlock exposed as MCP server for external Claude instances — **OPEN**
+- **Scenario C**: Offline operation via Ollama — **COMPLETE**
+
+---
+
+## MCP Server (Expose Tools to Claude) — NOT STARTED
+
+Create an MCP server that exposes Tatlock's household tools to external Claude instances.
+

+# Housekeeper Agent Optimization Findings
+
+## Background
+
+Research with Gemini identified key issues with mistral-nemo and tool calling:
+- "Pre-computation Hallucination" - model answers before using tools
+- High default temperature (0.7-0.8) causes wandering
+- Model is "chatty and confident" - needs explicit constraints
+
+## Key Recommendations from Gemini Research
+
+1. **Temperature 0.0** for tool-calling agents (deterministic, follows schema)
+2. **Chain of Thought (CoT)** - force step-by-step reasoning
+3. **Negative constraints** - tell model what NOT to do (Nemo responds better)
+4. **Explicit tool descriptions** - verbose docstrings with "never estimate yourself"
+5. **"Strictly tool-based assistant"** pattern - NO internal knowledge claim
+
+---
+
+## Experiment Log
+
+### Baseline (v1.8.6)
+- **Date**: 2025-12-17
+- **Configuration**: Default temperature, improved prompt requiring list_devices first
+- **Results**:
+  - Called list_devices first ✓
+  - Still hallucinated `light.study_desk` despite seeing list with only `light.study` and `light.study_main`
+  - Partial success: turned off `light.study_main`, failed on hallucinated entity
+- **Success rate**: ~50% (1 of 2 study lights controlled correctly)
+
+---
+
+### Experiment 1: Temperature 0.0
+- **Date**: 2025-12-18
+- **Change**: Set `model_settings=ModelSettings(temperature=0.0)` for Housekeeper
+- **Hypothesis**: Deterministic output will force model to use exact entity IDs from tool results
+- **Results**:
+
+  **Study lights test:**
+  - Called `list_devices()` first ✓ (but no domain filter)
+  - Used wrong parameter `device_id` instead of `entity_id` (recovered after validation error)
+  - Only identified `light.studeerlamp` as "study" related (Dutch name)
+  - **Missed `light.study` and `light.study_main`** - didn't match English "study"
+  - Turned off 1 wrong light, missed 2 actual study lights
+
+  **Kitchen lights test:**
+  - Called `list_devices()` first ✓ (no domain filter)
+  - Saw full device list including `light.kitchen`
+  - Used wrong parameter `device_id` instead of `entity_id` (recovered after validation)
+  - After correction, dropped domain prefix: used `kitchen` instead of `light.kitchen`
+  - 404 error - device not found
+
+- **Success rate**: 0% (no target lights successfully controlled)
+- **Observations**:
+  - Temperature 0.0 alone is insufficient
+  - Model consistently confuses `device_id` vs `entity_id` parameter name
+  - After validation error correction, model truncates entity_id (drops domain prefix)
+  - Semantic matching of room names to devices is weak
+  - Model doesn't understand entity_id format: `domain.name`
+
+---
+
+### Experiment 2: Negative Constraints + CoT
+- **Date**: 2025-12-18
+- **Change**: Complete prompt rewrite with:
+  - "You have NO Internal Knowledge" - negative framing
+  - Explicit entity_id format with WRONG/RIGHT examples
+  - Step-by-step process (ALWAYS FOLLOW)
+  - Explicit parameter names section
+  - "What NOT To Do" negative constraints
+- **Hypothesis**: Negative constraints work better with Mistral-Nemo
+- **Results**:
+
+  **Study lights test:**
+  - Called `list_devices(domain="light")` ✓ with domain filter (improvement!)
+  - Still used `device_id` first, recovered to `entity_id` after validation error
+  - After recovery, used correct full format: `light.studeerlamp`
+  - **Still only matched `studeerlamp` not `light.study` or `light.study_main`**
+
+  **Kitchen lights test:**
+  - Called `list_devices(domain="light")` ✓
+  - Called `turn_off(entity_id="light.kitchen")` ✓ correct format!
+  - All 4 kitchen lights turned off (light.kitchen is a group)
+  - **100% success for kitchen!**
+
+- **Success rate**:
+  - Study: 0% (wrong semantic match)
+  - Kitchen: 100% (4/4 lights off)
+  - Combined: ~50% (1 of 2 tests successful)
+- **Observations**:
+  - Domain filter now consistently used ✓
+  - Entity_id format correct after recovery ✓
+  - Semantic matching still fails for "study" → prefers Dutch "studeerlamp" over English "study"
+  - Parameter name confusion persists (`device_id` vs `entity_id`)
+  - Simple room names (kitchen) work; mixed language fails (study/studeerlamp)
+
+---
+
+### Experiment 3: Temperature 0.1 + Explicit Tool Docstrings
+- **Date**: 2025-12-18
+- **Change**:
+  - Temperature 0.1
+  - Updated turn_on/turn_off docstrings with explicit `entity_id=` in examples
+- **Results**:
+  - Still uses `device_id` first, recovers to `entity_id` after validation
+  - Still picks wrong entity (studeerlamp over study)
+- **Success rate**: 0%
+
+---
+
+### Experiment 4: Room Group Priority (with explicit examples)
+- **Date**: 2025-12-18
+- **Change**: Updated prompt with:
+  - Explicit instruction: "Look for EXACT match `light.<room_name>` first!"
+  - Concrete examples: "For 'study lights' → look for `light.study`"
+  - Working example showing `turn_off(entity_id="light.study")`
+- **Hypothesis**: Explicit examples will guide model to use room groups
+- **Results**:
+
+  **Test 1 & 2 (consecutive):**
+  - Called `list_devices(domain="light")` ✓
+  - Device list clearly shows `light.study` at the bottom
+  - First call: `turn_off({"devices":["studeerlamp"]})` - wrong param AND wrong device
+  - After validation error: `turn_off(entity_id="light.studeerlamp")` - correct param, still wrong device
+  - **Completely ignored `light.study` despite prompt explicitly saying to use it**
+
+- **Success rate**: 0% (wrong device controlled)
+- **Observations**:
+  - Model ignores explicit step-by-step instructions in favor of substring matching
+  - Dutch "studeerlamp" contains "studer" which the model prefers over exact "study" match
+  - Even when prompt has a literal example `turn_off(entity_id="light.study")`, model uses `light.studeerlamp`
+  - Positional bias possible - `light.study` appears at end of 21-item list
+  - **Fundamental limitation**: Mistral-Nemo cannot follow explicit matching rules
+
+---
+
+### Experiment 5: Room Groups First (Tool Output Ordering)
+- **Date**: 2025-12-18
+- **Change**: Modified `list_devices` to sort room groups to top of list using HA attributes (`is_hue_group`, `hue_type="room"`)
+- **Hypothesis**: Positional bias - model focuses on items earlier in list
+- **Results**:
+  - Room groups (`light.study`, `light.kitchen`, etc.) now appear first in device list
+  - Combined with improved prompt, model now consistently uses room groups
+  - **70% success rate** (7/10 tests) with default q4 quantization
+
+---
+
+### Experiment 6: Model Quantization (q5_1)
+- **Date**: 2025-12-18
+- **Change**: Upgraded from default Mistral-Nemo quantization (q4) to `mistral-nemo:12b-instruct-2407-q5_1`
+- **Hypothesis**: Higher precision weights improve tool calling accuracy
+- **Results**:
+
+  | Test | Action | Result |
+  |------|--------|--------|
+  | 1 | Turn off study | PASS |
+  | 2 | Turn on study | PASS |
+  | 3 | Toggle study | PASS |
+  | 4 | Turn off kitchen | PASS |
+  | 5 | Turn on kitchen | PASS |
+  | 6 | Toggle kitchen | PASS |
+  | 7 | Turn off bedroom | PASS |
+  | 8 | Turn on bedroom | PASS |
+  | 9 | Turn off living room | PASS |
+  | 10 | Turn on living room | PASS |
+
+- **Success rate**: **100%** (10/10 tests)
+- **Observations**:
+  - q5_1 quantization dramatically improves tool calling accuracy
+  - All room groups correctly identified and used
+  - No parameter confusion (`entity_id` used correctly)
+  - No entity_id truncation issues
+  - Toggle operations now work reliably
+  - Model fits within 10GB VRAM (q6 did not)
+
+---
+
+### Experiment 7: Device List in System Prompt (Context Injection)
+- **Date**: [PENDING]
+- **Change**: Store device list in database (per user/household) and inject into system prompt
+- **Approach**:
+  1. Periodically sync device list from Home Assistant to PostgreSQL
+  2. On each Housekeeper invocation, fetch device list and include in prompt
+  3. Remove need for model to call list_devices() - just match from context
+- **Hypothesis**:
+  - Eliminates tool call step where errors occur
+  - Reduces context size by not returning full device list as tool output
+  - Makes entity matching a language task (in prompt) rather than tool result parsing
+- **Trade-offs**:
+  - Stale data if sync is infrequent
+  - Prompt size increase (but less than tool call response)
+  - Need sync mechanism and storage
+- **Results**: [TO BE RECORDED]
+- **Success rate**: [TO BE RECORDED]
+
+---
+
+## Key Problem Identified (Solved)
+
+The model struggled with:
+1. **Parameter schema adherence** - uses `device_id` when schema requires `entity_id`
+2. **Value preservation** - truncates values after validation errors (drops `light.` prefix)
+3. **Semantic matching** - prefers substring matches ("studeerlamp" contains "studer") over exact matches (`light.study`)
+4. **Following explicit instructions** - ignores step-by-step processes even when examples are provided
+5. **Positional bias** - may not "see" items at the end of long lists
+
+**Solution**: These issues were resolved by:
+1. Using q5_1 quantization instead of default q4 (higher precision weights)
+2. Sorting room groups to top of device list (address positional bias)
+3. Explicit prompt guidance with negative constraints and examples
+
+---
+
+## Potential Next Experiments
+
+### Experiment 5: Room Groups First (List Ordering)
+- **Hypothesis**: Positional bias - model focuses on items earlier in list
+- **Change**: Sort device list to put room groups (entities matching `light.<single_word>`) at the TOP
+- **Effort**: Low - modify list_devices output formatting
+- **Risk**: May affect other use cases where individual devices are needed
+
+### Experiment 6: Simplified Device List Format
+- **Hypothesis**: Markdown formatting adds noise that confuses the model
+- **Change**: Return simple list: `light.study (Study - GROUP), light.study_main (Ceiling light), ...`
+- **Effort**: Low - modify list_devices output
+- **Risk**: Less human-readable responses
+
+---
+
+## Learnings to Apply Elsewhere
+
+1. **Quantization matters** - q5_1 dramatically outperforms q4 for tool calling (100% vs 70%)
+2. **Positional bias is real** - sort important items to top of lists
+3. **Smaller models need simpler workflows** - fewer tool calls, more context injection
+4. **Validation errors don't teach** - model often makes worse mistakes on retry
+5. **Entity IDs are hard** - domain.name format confuses the model
+6. **Consider pre-computation** - move matching logic to code, not LLM
+7. **Use explicit negative constraints** - "NEVER do X" works better than "always do Y"
+
+---
+
+## Notes
+
+- Librarian may need higher temperature for creative synthesis
+- All "action" agents (Housekeeper, future agents) should use low temperature
+- Consider testing with Gemma 2 9B for better function calling (Google, open weights)

+  "extraction_time_ms": 3500
+}
+```
+
+---
+
+## 3. Error Pattern: Soft Failures
+
+> **Important:** Content extraction uses a **soft failure pattern** - individual URL failures do NOT throw HTTP errors.
+
+### Why Soft Failures?
+
+When extracting content from multiple URLs (batch) or even single URLs:
+- Some sites block bots
+- Some URLs are temporarily down
+- Some pages have no extractable content
+
+Instead of failing the entire request, we return:
+- `success: true/false` per result
+- `error: "reason"` when failed
+- Empty `content: ""` on failure
+
+### Handling Soft Failures
+
+```python
+async def extract_with_fallback(url: str) -> str:
+    response = await client.post(
+        f"{BASE_URL}/content/extract",
+        headers={"Authorization": f"Bearer {API_KEY}"},
+        json={"url": url}
+    )
+    response.raise_for_status()  # Only throws on 4xx/5xx
+
+    data = response.json()
+    result = data["result"]
+
+    if result["success"]:
+        return result["content"]
+    else:
+        # Log the failure, return empty or handle gracefully
+        logger.warning(f"Extraction failed for {url}: {result['error']}")
+        return ""  # Or raise, or use cached version, etc.
+```
+
+### Batch Processing Example
+
+```python
+async def extract_batch_with_stats(urls: list[str]) -> dict:
+    response = await client.post(
+        f"{BASE_URL}/content/extract/batch",
+        headers={"Authorization": f"Bearer {API_KEY}"},
+        json={"urls": urls, "max_length": 3000}
+    )
+    response.raise_for_status()
+
+    data = response.json()
+
+    # Separate successful and failed
+    successful = [r for r in data["results"] if r["success"]]
+    failed = [r for r in data["results"] if not r["success"]]
+
+    if failed:
+        logger.warning(f"{len(failed)} URLs failed extraction:")
+        for f in failed:
+            logger.warning(f"  {f['url']}: {f['error']}")
+
+    return {
+        "contents": {r["url"]: r["content"] for r in successful},
+        "failed_urls": [f["url"] for f in failed],
+        "success_rate": data["successful"] / data["total_urls"]
+    }
+```

+### Research Flow
+
+```python
+async def librarian_research(topic: str) -> dict:
+    """
+    Full research flow: search + extract additional context.
+    """
+    # 1. Search for relevant pages
+    search_results = await search_web(topic, limit=10)
+
+    # 2. RAG search already includes extracted content
+    #    Only extract more if you need deeper content
+
+    # 3. Build context for LLM
+    context_parts = []
+    for r in search_results["results"]:
+        content = r["content"] or r["snippet"]

+
+## 5. Rate Limits & Best Practices
+
+| Recommendation | Reason |
+|----------------|--------|
+| Use `limit: 5-10` for searches | More results = longer extraction time |
+| Batch URLs when possible | More efficient than sequential calls |
+| Max 20 URLs per batch | Server limit |
+| Set reasonable timeouts (30s) | Content extraction can be slow |
+| Cache results client-side | Same URL rarely changes content |
+| Use `user` parameter | Helps with debugging and rate limiting |
+
+---
+
+## 6. Quick Reference
+
+| Endpoint | Method | Use Case |
+|----------|--------|----------|
+| `/rag/search` | POST | Search web + get extracted content |
+| `/content/extract` | POST | Read a single URL |
+| `/content/extract/batch` | POST | Read multiple URLs |
+| `/health` | GET | Check service status |

+# Testing Improvements for LLM Outputs
+
+## Problem
+
+LLM outputs are non-deterministic. Tests checking for exact string matches fail when the LLM writes "thirty-seven" instead of "37".
+
+## Proposed Solutions
+
+### 1. LLM-as-Judge Pattern
+
+Use a smaller/faster model to evaluate semantic correctness:
+
+```python
+async def llm_judge(output: str, criteria: str) -> bool:
+    """Use LLM to evaluate if output meets criteria."""
+    prompt = f"""
+    Evaluate if this output is correct:
+    Output: {output}
+    Criteria: {criteria}
+    Answer only YES or NO.
+    """
+    result = await judge_model.run(prompt)
+    return "YES" in result.output.upper()
+
+# Usage in test:
+assert await llm_judge(
+    response,
+    "The answer correctly states that sqrt(144) + 25 = 37"
+)
+```
+
+### 2. Fuzzy/Regex Matching
+
+For numeric answers, accept multiple representations:
+
+```python
+import re
+
+def contains_number(text: str, number: int) -> bool:
+    """Check if text contains number in any form."""
+    patterns = [
+        rf'\b{number}\b',  # Digit form
+        number_to_words(number),  # Word form
+    ]
+    return any(re.search(p, text, re.I) for p in patterns)
+
+# Usage:
+assert contains_number(response, 37)  # Matches "37" or "thirty-seven"
+```
+
+### 3. DeepEval Framework
+
+```python
+from deepeval.metrics import AnswerRelevancyMetric
+from deepeval.test_case import LLMTestCase
+
+def test_calculation():
+    test_case = LLMTestCase(
+        input="What is sqrt(144) + 25?",
+        actual_output=response,
+        expected_output="37"
+    )
+    metric = AnswerRelevancyMetric(threshold=0.7)
+    assert metric.measure(test_case)
+```
+
+### 4. pytest-evals Plugin
+
+Minimal pytest plugin for LLM testing with metrics collection.
+
+```bash
+pip install pytest-evals
+```
+
+### 5. Multiple Runs with Threshold
+
+Run flaky tests multiple times and require majority pass:
+
+```python
+@pytest.mark.flaky(reruns=3, reruns_delay=1)
+def test_llm_response():
+    ...
+```
+
+Or custom:
+
+```python
+@pytest.mark.parametrize("run", range(3))
+def test_llm_response(run):
+    ...
+    # Aggregate results across runs
+```
+

+
+## Implementation Priority
+
+1. Add fuzzy number matching helper (quick win)
+2. Evaluate DeepEval for complex output testing
+3. Consider LLM-as-judge for semantic correctness

+
+## CRITICAL: You Have NO Internal Knowledge
+
+You do NOT know what devices exist. You do NOT know any entity IDs.
+Entity IDs are different in every installation. You MUST discover them using tools.
+
+## Entity ID Format
+
+Entity IDs follow the format: `domain.name`
+Examples: `light.kitchen`, `light.study_main`, `switch.coffee_maker`
+
+The `entity_id` parameter MUST be the COMPLETE value including the domain prefix.
+WRONG: `entity_id="kitchen"`
+RIGHT: `entity_id="light.kitchen"`
+
+## Step-by-Step Process (ALWAYS FOLLOW)
+
+When asked to control devices in a room:
+
+1. THINK: What domain? (light, switch, climate, etc.)
+2. CALL: list_devices(domain="light") to discover available devices
+3. CHECK: Look for EXACT match `light.<room_name>` first!
+   - For "study lights" → look for `light.study` (not light.study_main, not light.studeerlamp)
+   - For "kitchen lights" → look for `light.kitchen` (not light.kitchen_spot_1)
+   - These room groups control ALL lights in that room at once
+   - If found, use ONLY the group (stop looking for individual lights)
+4. FALLBACK: Only if no exact room group exists, find entity_ids containing the room name
+5. CALL: turn_on/turn_off using the EXACT entity_id from step 3 or 4
+
+Example for "Turn off study lights":
+1. Domain is "light"
+2. Call list_devices(domain="light")
+3. Look for room group: `light.study` - FOUND!
+4. Call turn_off(entity_id="light.study")  # This controls all study lights
+
+Example for "Turn off hallway lights" (no room group):
+1. Domain is "light"
+2. Call list_devices(domain="light")
+3. Look for room group: `light.hallway` - NOT FOUND
+4. Find all with "hallway": light.hallway_spot_1, light.hallway_spot_2
+5. Call turn_off for each
+
+## Tool Parameter Names
+
+- turn_on, turn_off, toggle: Use `entity_id` (NOT device_id, NOT id)
+- activate_scene: Use `scene_id`
+- run_script: Use `script_id`
+
+## What NOT To Do
+
+- NEVER guess an entity_id
+- NEVER construct an entity_id from the room name
+- NEVER drop the domain prefix (light., switch., etc.)
+- NEVER use "device_id" - the parameter is called "entity_id"
+- NEVER provide an answer without calling list_devices first
+
+## Response Format
+
+After completing actions, briefly confirm:
+- Which devices were affected (list the entity_ids)
+- Whether each action succeeded or failed

-   - Use this for ANY information that might be current, factual, or outside your training data

+   - Use: delegate_to_librarian(task="search the web for ...")

 ## Tool Usage Guidelines
 
 - **Mathematics**: ALWAYS use the calculator tool, even for simple arithmetic
 - **Dates/Times**: ALWAYS use the date/time tools, never guess or estimate
-- **Current Information**: ALWAYS search for facts, news, or volatile information
+- **Current Information**: Delegate web searches to the Librarian
-- **Verification**: When facts are important, use search to verify rather than rely on memory alone
+- **Verification**: When facts are important, delegate to Librarian for research
 - When you use a tool, explain what you're doing in a butler-appropriate manner
 - Present tool results naturally in your response
 
-Currently in Phase 1 development - expert agent delegation will be added in later phases.
+## Expert Delegation (CRITICAL)
+
+When you see "DELEGATE:" in your instructions, you MUST delegate to the appropriate agent.
+
+**PRIMARY METHOD**: Call the delegation function directly:
+- `delegate_to_librarian(task="...")` for research/wiki tasks
+- `delegate_to_biographer(task="...")` for memory tasks
+
+**FALLBACK METHOD**: If function calling fails, output EXACTLY this format:
+```
+[DELEGATE:biographer] task="Remember that user's name is TestBot"
+```
+or
+```
+[DELEGATE:librarian] task="Search for information about Docker"
+```
+
+**Rules:**
+1. When you see "DELEGATE: biographer" - delegate to biographer
+2. When you see "DELEGATE: librarian" - delegate to librarian
+3. NEVER ask for confirmation - just delegate
+4. NEVER handle delegated tasks yourself
+5. If you cannot call the function, use the [DELEGATE:...] text format EXACTLY

-## What These Tests Verify
+## Test Organization
 
-### 1. Chat Completions Endpoint (`/v1/chat/completions`)
+### `test_api_endpoints.py` - Core API Tests
 
-- ✅ Simple calculations trigger calculator tool
+- Chat Completions endpoint (`/v1/chat/completions`)
-- ✅ Search queries trigger web search
+- Responses API endpoint (`/v1/responses`)
-- ✅ Multi-turn conversations maintain context
+- Streaming responses
-- ✅ Complex requests use multiple tools
+- Error handling
-- ✅ Simple greetings don't trigger unnecessary tools
+- OpenAI format compliance
-- ✅ Date/time queries trigger datetime tools
 
-### 2. Responses API Endpoint (`/v1/responses`)
+### `test_orchestration_e2e.py` - Orchestration Scenario Tests
 
-- ✅ Reasoning output includes Steward's analysis
+Based on `ORCHESTRATION_SCENARIOS.md`:
-- ✅ Multi-turn conversations show in Steward reasoning

+| Class | Scenario | What it Tests |
+|-------|----------|---------------|
+| `TestMemoryStorage` | Memory storage | Store -> Qdrant verification |
+| `TestMemoryRecall` | Memory recall | Store -> Recall flow |
+| `TestStewardDelegation` | Steward routing | Capability recommendations |
+| `TestDirectDelegation` | Direct bypass | Pure memory/librarian requests |
+| `TestScenario1WeatherWithMemory` | Weather check | Multi-step with memory lookup |
+| `TestScenario4SimpleExpertDelegation` | Calculator/datetime | Simple tool use |
+| `TestScenario6WikiCreation` | Wiki operations | Librarian delegation |
+| `TestScenario8MultiExpertCoordination` | Complex requests | Multiple capabilities |
+| `TestUserContextIsolation` | User isolation | llm_tester vs production |
+| `TestDataVerification` | Data presence | Qdrant structure verification |
+| `TestIntegrationHealth` | System health | API/Qdrant reachability |
+| `TestEvaluationReport` | Diagnostic | Generates behavior reports |
 
-- ✅ Chat completions streaming works
+## User Isolation
-- ✅ Steward reasoning appears in stream
-- ✅ Proper SSE format with chunks
 
-### 4. Error Handling
+Tests use the `llm_tester` user (development environment default) to isolate test data from production:
 
-- ✅ Invalid model returns 404
+- Test memories: `memories_llm_tester` (Qdrant collection)
-- ✅ Missing required fields return 422
+- Production memories: `memories_jpmschweitzer` (never modified by tests)
-- ✅ Invalid parameters return 422
 
-### 5. Steward Integration
+## Handling LLM Non-Determinism
 
-- ✅ Steward recommends correct capabilities
+LLM outputs are non-deterministic. Tests handle this by:
-- ✅ Steward detects conversation context
-- ✅ Steward analysis appears in all responses
 
-## Expected Behavior
+1. **Flexible assertions** - Check for behavior patterns, not exact text
+2. **`assert_llm_behavior()`** - Helper for pattern matching with confidence levels
+3. **Soft failures (`pytest.xfail`)** - Some tests may fail due to LLM variance without failing the suite
+4. **Evaluation reports** - Generate diagnostic reports for human review
 
-When tests run, you should see in the server logs:
+Example:
-
+```python
-```
+result = assert_llm_behavior(
-INFO     creating_response_with_steward
+    message_text,
-INFO     preprocessing_request
+    expected_patterns=[r"(remember|noted|stored)", r"purple"],
-INFO     operation_started             operation=steward_analysis
+    min_matches=1,
-INFO     steward_analysis_complete     recommended=[...] complexity=simple
+)
-INFO     tatlock_run_with_scoped_tools
+if not result.passed:
-INFO     tatlock_response_generated
+    pytest.xfail(f"LLM response unclear: {result.evidence}")
-INFO     tool_tracking_finalized
 ```
 
-## Test Scenarios
+## Data Verification
 
-### Simple Calculation
+Tests verify data presence in Qdrant:
-```
-User: "What is 144 divided by 12?"
-Expected: Calculator tool used, answer is "12"
-```
 
-### Web Search
+```python
-```
+# QdrantVerifier helper
-User: "What is the capital of France?"
+qdrant = QdrantVerifier()
-Expected: Search may be used, answer mentions "Paris"
+points = await qdrant.scroll_points("memories_llm_tester")
-```
+memory = await qdrant.find_memory_by_key("memories_llm_tester", "favorite_color")
-
-### Multi-Turn
-```
-User: "What is 15 times 4?"
-Assistant: "60"
-User: "Now add 20 to that result."
-Expected: Context recognized, answer is "80"
-```
-
-### Combined Tools
-```
-User: "Calculate the square root of 256, then search for what number squared equals that result."
-Expected: Both calculator and search recommended
-```
-
-### Date/Time
-```
-User: "What is today's date?"
-Expected: Datetime tool used, current date returned

 ```
 
 ### Tests timeout
 
-- Check that Ollama is running and responsive
+- Check Ollama is running: `curl http://localhost:11434/api/tags`
-- Increase timeout in test file if needed (default: 60s)
+- Increase timeout if needed (default: 120s for LLM calls)
 
-### Tool usage not detected
+### Memory tests fail
 
-- Check server logs to see if tools are actually being called
+- Check Qdrant is running: `curl http://localhost:6333/collections`
-- Verify Steward preprocessing is happening (look for `steward_analysis` logs)
+- Verify `memories_llm_tester` collection exists
 
 ### Inconsistent results
 
-- LLM responses can vary - tests check for key indicators rather than exact text
+- LLM responses vary - this is expected
-- If a test occasionally fails, it might be due to LLM variance
+- Check the evaluation report for detailed diagnostics:
-- Check the actual response content in the test output
+  ```bash
+  pytest tests/e2e/test_orchestration_e2e.py::TestEvaluationReport -v -s
+  ```
 
-## Coverage
+### Tests pollute production data
 
-These tests complement the unit and integration tests by:
+- This shouldn't happen - tests use `llm_tester` user
+- If it does, check `ENVIRONMENT` is set to `development` in `.env`
 
-1. **Testing the full HTTP stack** - Request parsing, routing, middleware
+## Adding New Tests
-2. **Testing real LLM behavior** - Not mocked, actual Ollama responses
-3. **Testing real tool execution** - Calculator, datetime, search actually run
-4. **Testing Steward preprocessing** - Real analysis and tool scoping
-5. **Testing error handling** - HTTP error codes and error responses
 
-Together with unit/integration tests, this provides comprehensive coverage of the entire system.
+1. Use existing fixtures (`client`, `qdrant`, `clean_test_memories`)
+2. Use `assert_llm_behavior()` for flexible LLM output checking
+3. Add `@pytest.mark.e2e` decorator
+4. Consider adding soft failures for non-deterministic checks
+5. Add test keys to `clean_test_memories` fixture if storing new memories
+
+Example:
+```python
+@pytest.mark.e2e
+@pytest.mark.asyncio
+class TestNewScenario:
+    async def test_something(
+        self,
+        client: httpx.AsyncClient,

+        # Use assert_llm_behavior for flexible checking
+        result = assert_llm_behavior(response_text, expected_patterns=[...])
