feat: environment-aware config, direct delegation, E2E test suite (v1.4.0)

### Added
- Environment-aware configuration:
  - Auto-selected logging (DEBUG for dev, WARNING for prod)
  - Auto-selected default user (llm_tester for dev isolation)
  - User context logging at request entry
- Direct delegation bypass:
  - Pure memory/librarian requests skip Tatlock LLM
  - Reduces latency for memory-only requests
- Text-based delegation fallback:
  - Parse [DELEGATE:agent] patterns from LLM output
  - Sequential and parallel execution support
- Comprehensive E2E test suite:
  - 22 orchestration tests with QdrantVerifier
  - assert_llm_behavior() for flexible pattern matching
  - Tests for memory, delegation, isolation, scenarios

### Fixed
- Unit test mocks for streaming (async generator)
- Temporal context handling in tests
- LLM non-determinism with pytest.xfail()
- Streaming test timeouts increased

 * **Reflect:** After coding, verify your work. Did you break existing tests? Did you add new tests?
 
+### 🧪 Local Development Setup
+* **Always test locally first** before committing and deploying. The build-deploy loop is slow.
+* **Start the local server** with `./wakeup.sh` - logs are written to `logs/server.log` for easy tailing
+* **Auto-reload**: The wakeup script runs uvicorn in reload mode - code changes are picked up automatically without restart (except for requirements.txt changes)
+* **Test REST endpoints** against `http://localhost:8123` using curl or similar tools
+* **Only deploy** when a phase or feature is complete and tested locally
+* **Environment**: Copy `.env.example` to `.env` and configure for your local setup (Ollama, Redis, Qdrant hosts)

 ## [Unreleased]
 
+## [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

-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:

+```
+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
-- ✅ Search queries trigger web search
-- ✅ Multi-turn conversations maintain context
-- ✅ Complex requests use multiple tools
-- ✅ Simple greetings don't trigger unnecessary tools
-- ✅ Date/time queries trigger datetime tools
+- Chat Completions endpoint (`/v1/chat/completions`)
+- Responses API endpoint (`/v1/responses`)
+- Streaming responses
+- Error handling
+- OpenAI format compliance
 
-### 2. Responses API Endpoint (`/v1/responses`)
+### `test_orchestration_e2e.py` - Orchestration Scenario Tests
 
-- ✅ Reasoning output includes Steward's analysis
-- ✅ Multi-turn conversations show in Steward reasoning
-- ✅ Response structure follows OpenAI Responses format
+Based on `ORCHESTRATION_SCENARIOS.md`:
 
-### 3. Streaming
+| 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
-- ✅ Steward reasoning appears in stream
-- ✅ Proper SSE format with chunks
+## User Isolation
 
-### 4. Error Handling
+Tests use the `llm_tester` user (development environment default) to isolate test data from production:
 
-- ✅ Invalid model returns 404
-- ✅ Missing required fields return 422
-- ✅ Invalid parameters return 422
+- Test memories: `memories_llm_tester` (Qdrant collection)
+- Production memories: `memories_jpmschweitzer` (never modified by tests)
 
-### 5. Steward Integration
+## Handling LLM Non-Determinism
 
-- ✅ Steward recommends correct capabilities
-- ✅ Steward detects conversation context
-- ✅ Steward analysis appears in all responses
+LLM outputs are non-deterministic. Tests handle this by:
 
-## 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:

-## Test Scenarios
+## Data Verification
 
-### Simple Calculation
-```
-User: "What is 144 divided by 12?"
-Expected: Calculator tool used, answer is "12"
-```
+Tests verify data presence in Qdrant:
 
-### Web Search
-```
-User: "What is the capital of France?"
-Expected: Search may be used, answer mentions "Paris"
-```
-
-### 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
+```python

 Make sure the server is running:
 ```bash

+./wakeup.sh
+curl http://localhost:8123/health  # Should return 200
 ```
 
 ### Tests timeout
 
-- Check that Ollama is running and responsive
-- Increase timeout in test file if needed (default: 60s)
+- Check Ollama is running: `curl http://localhost:11434/api/tags`
+- 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
-- Verify Steward preprocessing is happening (look for `steward_analysis` logs)
+- Check Qdrant is running: `curl http://localhost:6333/collections`
+- Verify `memories_llm_tester` collection exists
 
 ### Inconsistent results
 
-- LLM responses can vary - tests check for key indicators rather than exact text
-- If a test occasionally fails, it might be due to LLM variance
-- Check the actual response content in the test output
+- LLM responses vary - this is expected
+- Check the evaluation report for detailed diagnostics:
+  ```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
-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
+## Adding New Tests
 
-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,
+        qdrant: QdrantVerifier,
+        clean_test_memories,
+    ):
+        response = await client.post("/v1/responses", json={...})
+        # Use assert_llm_behavior for flexible checking
+        result = assert_llm_behavior(response_text, expected_patterns=[...])
