fix(permissions): narrow rm -rf deny globs to their exact forms

The trailing wildcard on the three rm -rf deny entries spanned path
separators, so Bash(rm -rf /*) matched every absolute path on the
machine rather than the filesystem root, and the ~ and $HOME entries
had the same shape. Narrowed to the exact literal forms.

These rules match literal command text, so they still stop a typo on
rm -rf /, rm -rf ~ or rm -rf $HOME exactly, but they no longer stop a
recursive delete aimed at any other path. That reduced cover is
deliberate, not an oversight.

This is a dedicated programming pass, not lint tidying, and it is what currently blocks `make pre-push`.
+
+MEASURED 2026-08-11 so the next session does not re-derive it:
+
+  29 no-untyped-def   functions with no annotations — the bulk, and genuine per-function work
+  18 no-any-return    mostly downstream of the above
+  12 assignment
+  11 arg-type
+   5 unused-ignore    `# type: ignore` comments mypy says are no longer needed
+   5 union-attr
+   4 var-annotated
+   3 override
+   remainder: misc, dict-item, attr-defined, return-value, call-overload
+
+By file: agents/tatlock.py 15, core/memory_service.py 11, responses/streaming.py 8, responses/service.py 7, core/context.py 6.
+
+THE TWO SHARED ROOTS ARE ALREADY FIXED (dac259a), so what is left has no lever in it. For reference, they were: five conversation lists declared bare, where mypy infers the element type from the first append (a ModelRequest) and then rejects every ModelResponse; and an agent built as Agent(model, system_prompt=...) with no deps_type, inferred Agent[None, str], while every tool it registers takes RunContext[ToolCallTracker].
+
+WORTH KNOWING BEFORE STARTING. Annotating partially made mypy count go UP before it went down — declaring `_agent: Agent | None` took agents/tatlock.py from 22 to 24, because resolving the bare Agent to Agent[None, str] surfaced four argument-type errors the Any had been hiding. Expect that shape: a rising count during this work usually means concealment ending, not damage.
+
+The mypy config is strict — disallow_untyped_defs, disallow_incomplete_defs, warn_return_any, check_untyped_defs, strict_equality — so there is no partial-credit setting to lean on, and weakening it would be the wrong trade for a codebase this central.
+
+TWO PRE-EXISTING TEST FACTS, both confirmed at HEAD and neither caused by the lint work:
+  - test_tatlock_tool_call_logging_calculator is flaky: failed 2 of 5 full runs, on HEAD and on the lint branch, and fails in isolation at HEAD while passing in isolation after the lint pass. Order- or timing-dependent.
+  - `pytest tests/` cannot collect at all: tests/e2e/test_orchestration_e2e.py uses an `e2e` marker that is not registered and the config is strict about markers. `make test` passes only because it ignores tests/e2e, tests/integration and tests/contracts.', NULL, '2026-08-11 18:26:58', '2026-08-11 18:26:58.523', '2026-08-11 18:26:58.523', NULL, 'c8c9b6a20cf18ca903fc8c720f70e73d', 2) ON CONFLICT(hash) DO NOTHING;

That key was revoked and no longer exists on Anthropic''s side, so this is dead weight rather than an exposure — but it is dead weight that reads exactly like a live credential to anyone who finds it.
+
+The cost is confusion, not risk. Someone debugging a Claude fallback will find a key present, assume it is configured, and look elsewhere for the failure. The absence of a key is a clear signal; a revoked key is a misleading one.
+
+`.env` is gitignored here and has never been committed, so nothing needs rewriting — the value simply needs removing from the local file, and the line dropping or blanking in `.env.example` if it appears there too.
+
+RELATED, and the reason this is filed separately: the workspace vault holds T-13, "Clear the revoked ANTHROPIC_API_KEY from the live Portainer stack". That ticket is scoped to the Portainer stack only. Whoever closes it will reasonably believe the key is gone once the stack is clean, and this copy will survive. The two want doing together even though they commit separately.
+
+Context on the revocation, since it explains why nobody removed this at the time: the key was revoked on 2026-08-09 after being printed into a transcript by a redaction filter that matched on `KEY` appearing after the `=`. In `ANTHROPIC_API_KEY=...` it appears before, so the filter never fired.

+
+MEASURED 2026-08-11 so the next session does not re-derive it:
+
+  29 no-untyped-def   functions with no annotations — the bulk, and genuine per-function work
+  18 no-any-return    mostly downstream of the above
+  12 assignment
+  11 arg-type
+   5 unused-ignore    `# type: ignore` comments mypy says are no longer needed
+   5 union-attr
+   4 var-annotated
+   3 override
+   remainder: misc, dict-item, attr-defined, return-value, call-overload
+
+By file: agents/tatlock.py 15, core/memory_service.py 11, responses/streaming.py 8, responses/service.py 7, core/context.py 6.
+
+THE TWO SHARED ROOTS ARE ALREADY FIXED (dac259a), so what is left has no lever in it. For reference, they were: five conversation lists declared bare, where mypy infers the element type from the first append (a ModelRequest) and then rejects every ModelResponse; and an agent built as Agent(model, system_prompt=...) with no deps_type, inferred Agent[None, str], while every tool it registers takes RunContext[ToolCallTracker].
+
+WORTH KNOWING BEFORE STARTING. Annotating partially made mypy count go UP before it went down — declaring `_agent: Agent | None` took agents/tatlock.py from 22 to 24, because resolving the bare Agent to Agent[None, str] surfaced four argument-type errors the Any had been hiding. Expect that shape: a rising count during this work usually means concealment ending, not damage.
+
+The mypy config is strict — disallow_untyped_defs, disallow_incomplete_defs, warn_return_any, check_untyped_defs, strict_equality — so there is no partial-credit setting to lean on, and weakening it would be the wrong trade for a codebase this central.
+
+TWO PRE-EXISTING TEST FACTS, both confirmed at HEAD and neither caused by the lint work:
+  - test_tatlock_tool_call_logging_calculator is flaky: failed 2 of 5 full runs, on HEAD and on the lint branch, and fails in isolation at HEAD while passing in isolation after the lint pass. Order- or timing-dependent.
+  - `pytest tests/` cannot collect at all: tests/e2e/test_orchestration_e2e.py uses an `e2e` marker that is not registered and the config is strict about markers. `make test` passes only because it ignores tests/e2e, tests/integration and tests/contracts.', 'backlog', 'high', NULL, NULL, NULL, '2026-08-11 18:26:58.318', '2026-08-11 18:26:58.523', NULL, 'fc047dd080d976c4ca0c551cac8fec93', 2) ON CONFLICT(record_id) DO UPDATE SET type=excluded.type, parent_record_id=excluded.parent_record_id, title=excluded.title, description=excluded.description, status=excluded.status, priority=excluded.priority, assigned_to=excluded.assigned_to, team=excluded.team, decision_ref=excluded.decision_ref, updated_at=excluded.updated_at, deleted_at=excluded.deleted_at, hash=excluded.hash, canonical_version=excluded.canonical_version WHERE excluded.updated_at >= tickets.updated_at;

+RELATED, and the reason this is filed separately: the workspace vault holds T-13, "Clear the revoked ANTHROPIC_API_KEY from the live Portainer stack".

The two want doing together even though they commit separately.

-# LLM Agent Instructions
-
-This document contains instructions and documentation references for AI assistants working with this codebase.
-
-> **📖 Important**: Before working on this project, read [PHILOSOPHY.md](PHILOSOPHY.md) to understand the system vision, architectural patterns, and design goals. All development should work towards realizing those patterns.
-# AGENTS.md
-
-> **Start every session by reading this file.**
-> This file outlines the operational protocols, coding standards, and architectural decisions for this FastAPI project.
-
-## 1. Agent Operational Protocols
-
-### 🧠 Work Patterns (Plan-Act-Reflect)
-* **Plan:** Before writing code, briefly outline your plan. Identify which files you will touch and what the side effects might be.
-* **Act:** Execute the changes in small, atomic steps.
-* **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:8777` 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)
-* **Running tests**: Always use the venv explicitly to avoid environment mismatches:
-  ```bash
-  .venv/bin/python -m pytest tests/           # All tests
-  .venv/bin/python -m pytest tests/core/ -v   # Core tests only
-  ```
-
-### 🌐 Internal Service Access
-* **git.schweitz.net**: Access via `http://localhost:3002` (direct Gitea) to bypass Authentik SSO
-  * Example: `curl http://localhost:3002/jpmschweitzer/library-desk/raw/branch/main/README.md`
-  * Public repos are readable without authentication
-  * Related repos: `library-desk`, `scheduler`, `core-api`, `portainer-core`
-
-### 🐳 Deployment & Infrastructure
-* **Full stack documentation**: Available in the `portainer-core` repo
-  * Access: `curl http://localhost:3002/jpmschweitzer/portainer-core/raw/branch/main/CONTAINERS.md`
-  * Contains: All service ports, URLs, Redis DB allocations, external domains
-* **Tatlock deployment**:
-  * LAN: `http://192.168.86.149:8000`
-  * External: `tatlock.schweitz.net` (behind Authentik SSO)
-  * Redis DBs: 1 (memory), 6 (benchmarks)
-* **Health check**: `curl http://192.168.86.149:8000/health`
-
-### 🛡️ Git Discipline
-* **NEVER commit to `main` or `master` directly.** Always create a feature branch: `feature/your-feature-name` or `fix/issue-description`.
-* **Commit Messages:** Use the [Conventional Commits](https://www.conventionalcommits.org/) format.
-    * `feat: add user login endpoint`
-    * `fix: resolve database connection timeout`
-    * `refactor: split monolith dependency file`
-* **Atomic Commits:** Keep commits small. One logical change = one commit.
-
-### 📝 Changelog Maintenance
-* **Update `CHANGELOG.md`** with every user-facing change.
-* Format: `## [Unreleased] - YYYY-MM-DD` followed by `### Added`, `### Changed`, or `### Fixed`.
-
-### 🚀 Release Flow
-When changes are ready for deployment:
-
-1. **Ask user if deploy cycle is desired**
-
-2. **Update version** in `pyproject.toml`:
-   - Bug fixes: bump patch version (1.8.3 → 1.8.4)
-   - New features: bump minor version (1.8.4 → 1.9.0)
-
-3. **Update CHANGELOG.md**:
-   - Move items from `[Unreleased]` to new version section
-   - Add release date: `## [1.8.4] - 2025-12-16`
-
-4. **Commit and tag**:
-   ```bash
-   git add -A
-   git commit -m "fix: description of changes"
-   git tag v1.8.4
-   git push origin main --tags
-   ```
-
-5. **CI/CD triggers automatically**:
-   - Gitea CI builds Docker image on new tag
-   - Watchtower pulls and deploys to production
-   - Verify deployment: `curl http://192.168.86.149:8000/health`

-## 2. FastAPI Architecture & Best Practices
-*Reference: [FastAPI Best Practices](https://github.com/zhanymkanov/fastapi-best-practices)*

-### 📂 Project Structure (Directory-based, NOT File-type based)

@@ -7,6 +7,273 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 
 ## [Unreleased]
 
+### Changed
+
+- `make setup` now ends with a `pytest --collect-only` pass so a broken environment
+  (missing or mismatched dependency) fails the target itself instead of exiting 0
+  and surfacing later as a confusing test failure (T-47)
+
+## [2.4.3] - 2026-08-08
+
+### Fixed
+
+- Steward routing no longer triggers on words inside its own explanation. Capability
+  extraction reads the declared `DELEGATE:` line instead of substring-matching
+  capability domains across the whole response, where ordinary English routed
+  requests — "description" contains the housekeeper domain "script", "acknowledge"
+  contains "knowledge" and "know". A spurious capability meant a real agent call,
+  including web searches, on queries that needed none.
+
+## [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

+- **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
+  - 📑 icon for document sources in search results
+  - Librarian prompt updated with document awareness
+
+- **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
+
+#### Lightweight Request Tracing
+- **JSON-based tracing system** for local development debugging
+  - Captures full request flow through multi-agent architecture
+  - `Trace` and `Span` dataclasses with automatic timing and nesting
+  - ContextVar-based propagation for async-safe tracing
+  - `trace_span` async context manager for clean instrumentation
+  - Traces written to `logs/traces/{trace_id}.json`
+  - Enabled via `DEBUG=true` environment variable
+- **Trace Viewer UI** (`logs/traces/viewer.html`)
+  - Standalone HTML viewer with timeline visualization
+  - Filter by status, search by request text
+  - Expandable span details with prompts and responses
+- **Tracing REST API** (`/traces`)
+  - `GET /traces` - Serve trace viewer UI
+  - `GET /traces/list` - List available traces with filtering
+  - `GET /traces/{trace_id}` - Retrieve specific trace JSON
+  - Only available when `DEBUG=true`
+- **Full pipeline instrumentation**
+  - Router-level trace start/end with context management
+  - Steward analysis spans in preprocessing
+  - Tatlock orchestrate/synthesize spans
+  - Expert delegation spans (librarian/biographer/housekeeper)
+  - Tool-level spans extracted from PydanticAI messages
+
+### Changed
+
+- **Replaced Redis benchmarks with file-based tracing** - Simpler, more useful for debugging
+- **Context management moved to service layer** - Router simplified, context set in response service
+- **Server binds to all interfaces** - `wakeup.sh` now uses `0.0.0.0` for network access
+
+### Removed
+
+- **Redis benchmark system** (`src/core/benchmarks.py`)
+  - `ENABLE_BENCHMARKS` config setting
+  - `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 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

+# CLAUDE.md — tatlock
+
+Privacy-first homelab butler. An OpenAI-compatible orchestration API over local models, with
+household staff agents built on PydanticAI. Python 3.12 / FastAPI, `version = "2.4.3"`.
+Container `tatlock` on `docker-dataplane`, port **8000**. Redis DB **1** (memory), Qdrant for
+vectors.
+
+## Ports
+
+| | Port | How |
+|---|---|---|
+| Local dev | **8777** | `make run` — uvicorn reload, logs to `build/logs/server.log` |
+| Production | **8000** | container; `http://192.168.86.149:8000/health`, external `tatlock.schweitz.net` behind Authentik |
+
+Test endpoints against `localhost:8777` while developing. `localhost:8000` is the *container*.
+
+## Live contract
+
+`http://localhost:8000/openapi.json` — **5 paths**, `title: OpenAI-Compatible API`, `version:
+2.4.3` (verified 2026-08-09): `/`, `/health`, `/v1/models`, `/v1/chat/completions`,
+`/v1/responses`. `/v1/responses` is primary; `/v1/chat/completions` exists for Open WebUI.
+
+**The spec is the public surface, not the system.** The household capability registry is internal
+and appears nowhere in those 5 paths. Absence from the spec means "not exposed", not "does not
+exist".
+
+## Two traps that make the runtime look like the opposite of what it is
+
+**1. `src/anthropic` loads at startup; `src/ollama` does not — and Ollama is the primary
+backend.** A cold `import src.main` inside the container shows `agents, anthropic, chat, core,
+main, models, responses` — no `ollama`. The only import of it is a *function-body* one at
+`src/anthropic/model_selector.py:230`. Meanwhile `PREFER_CLOUD_BACKEND=false`, so every request
+actually goes to Ollama and the Claude path is off (see **workspace D-11**). Reading the module list
+naively gives you exactly the wrong answer: the package that looks live is the disabled fallback,
+and the one that looks dead is the hot path. Do not conclude anything about backends from
+`sys.modules`; read the config.
+
+**2. In-process singletons are empty outside the app.** `get_household_registry()`
+(`src/core/household_registry.py:334`) in a fresh `docker exec python` returns **0 members**,
+while the running app serves 2 models from it — it is populated at startup. Import the
+module-level definitions or ask the endpoint; never import a singleton and assume it is
+populated.
+
+## Stack decisions that bind this repo
+
+Recorded in the workspace vault, not here. Read before assuming anything about the LLM backend:
+
+```bash
+/home/jpmschweitzer/.local/bin/pql --vault /mnt/media/Projects decisions read workspace D-11
+```
+
+**workspace D-11 — the Claude migration is abandoned. Tatlock stays on Ollama.** Do not resume it and do
+not treat its remnants as unfinished work. What you will find, and why none of it is a TODO:
+`ANTHROPIC_MODEL` is set on the container (`claude-sonnet-4-20250514`) and never used because
+`PREFER_CLOUD_BACKEND=false`; `ANTHROPIC_API_KEY` is a variable reference whose literal was
+revoked 2026-08-09; `docs/claude-integration.md` documents a capability that exists but is
+switched off. The cost is deliberate: reasoning stays at `gemma4:e2b` scale because VRAM is
+shared with Speaches.
+
+`REDIS_BENCHMARK_DB=6` is allocated on the container but the benchmarking module was never
+implemented — see the gotcha below. Vestigial, like the Anthropic settings.
+
+## 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 it 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 raise `ScopeMismatch`. 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 — advisory at best.
+
+**Claude Sonnet 5+ rejects sampling parameters.** `temperature`/`top_p`/`top_k` return 400. Use
+`get_sampling_settings()` from the model selector rather than passing `ModelSettings(temperature=…)`
+to agents that can run on the Claude fallback. `make test-contracts` pins this.
+
+**Integration test timeouts** are 120s to match `OLLAMA_TIMEOUT` (300s for the pure-Ollama
+fallback test, which Claude cannot rescue). GPU-resident numbers measured 2026-08-07 with
+gemma4:e2b at ~95 tok/s: full Steward → orchestrate → synthesize ~10–13s for simple turns;
+librarian-routed ~20–25s (not re-measured). **A single turn costs 3 sequential Ollama calls and
+~710 generated tokens even for "what is 61 plus 12?"** — mostly the model's own reasoning, paid
+three times. Cold model load is ~36s, avoided while pinned with `keep_alive: -1`; the
+`OLLAMA_KEEP_ALIVE=2h` default reintroduces it. Older "~35s steward / ~2 min flow" and "11–25s"
+figures are superseded — do not plan against them. `STEWARD_TIMEOUT` defaults to 60s.
+
+**`get_benchmark_store` does not exist.** `src/core/benchmarks.py` was never implemented, and
+`scripts/benchmark_analysis.py` references it and is broken. Do not add mocks for it in tests.
+
+**Steward tests need the household registry.** Use `register_household_members()` (sync) in
+fixtures, not `initialize_application()` (async). The steward extracts capabilities from the
+registry.
+
+## Commands
+
+```bash
+make setup            # venv + all dependencies
+make run              # dev server on 8777, reload, logs to build/logs/server.log
+make test             # unit tests, no external services
+make test-integration # needs Ollama (and Claude, if enabled)
+make test-contracts   # wire-level contract tests against live service boundaries
+make lint             # ruff linter + formatter check
+make typecheck        # mypy
+make clean            # remove caches and build artifacts
+```
+
+Always run pytest through the venv explicitly, to avoid environment mismatch:
+
+```bash
+.venv/bin/python -m pytest tests/
+.venv/bin/python -m pytest tests/core/ -v
+```
+
+Dependencies live in `pyproject.toml` (`[project.dependencies]`, `[project.optional-dependencies.dev]`).
+Copy `.env.example` to `.env` and configure Ollama, Redis and Qdrant hosts.
+
+**Contract tests before code review.** When the question is "do these two services still agree?",
+`make test-contracts` answers it by observing the live boundary; reading both codebases only tells
+you what should happen. Semantics: unreachable → skip, reachable-but-wrong-shape → fail.
+
+## Architecture
+
+Domain-first under `src/`: `agents/` (steward, librarian, biographer, housekeeper, tatlock_core),
+`core/`, `chat/`, `responses/`, `models/`, `ollama/`, `anthropic/`. Two tiers — the Steward routes,
+Tatlock coordinates. Group new work by domain, not by file type.
+
+## Internal service access
+
+`http://localhost:3002` reaches Gitea directly, bypassing Authentik SSO — verified returning
+`{"version":"1.27.1"}`. Useful for reading a sibling repo's raw files:
+
+```bash
+curl http://localhost:3002/jpmschweitzer/library-desk/raw/branch/main/README.md
+```
+
+The old AGENTS.md pointed at **`portainer-core`** for full-stack documentation. That repo is
+**deprecated** and must not be used as a source of infra facts; it was merged into
+`system-admin-toj/containers/`, where `CONTAINERS.md` is the live inventory.
+
+## Work tracking
+
+Work lives in **pql**, not a markdown TODO. **This repo's vault is standalone** — its tickets and
+internal decisions live here in `.pql/` and `governance/`, and travel with a clone, because
+`.pql/changelog/` is committed and replayed by the git hooks (workspace D-15). The databases are gitignored
+and rebuildable with `pql plan rebuild`.
+
+`pql` is **not** on the non-interactive `PATH` — invoke it as `/home/jpmschweitzer/.local/bin/pql`.
+From inside this repo no `--vault` is needed; pql anchors at the nearest `.git/` ancestor.
+
+```bash
+/home/jpmschweitzer/.local/bin/pql ticket list        # this repo's open work
+/home/jpmschweitzer/.local/bin/pql plan whatsnext     # next unblocked item, with context
+/home/jpmschweitzer/.local/bin/pql decisions list     # this repo's own decisions
+```
+
+Stack decisions that constrain this service need the flag:
+
+```bash
+/home/jpmschweitzer/.local/bin/pql --vault /mnt/media/Projects decisions list --domain tatlock-api
+```
+
+The workspace domain is `tatlock-api`, not `tatlock` — pql rejects a domain stem that prefixes
+another, and `tatlock` prefixes `tatlock-ui`. A `tatlock-api -> tatlock` symlink at the workspace
+root makes the directory answer to both (workspace D-15).
+
+Note `ticket new --decision D-N` resolves ids within **one** vault, so a ticket here cannot link
+to a workspace decision. Cite the id in the ticket body instead.
+
+## Git
+
+- **History is linear — no merge commits.** Work on `main`, or a short-lived branch that is
+  fast-forwarded and deleted. This repo's AGENTS.md mandated a feature branch for every change;
+  that rule was retired workspace-wide on 2026-08-08 and does not apply.
+- **Conventional Commits**: `feat:`, `fix:`, `refactor:`, `docs:`, `chore:`.
+- **Stage explicitly. Never `git add -A`** — denied by policy, and it sweeps in whatever else is
+  dirty, including secrets.
+- Update `CHANGELOG.md` for every user-facing change, under `[Unreleased]`.
+
+## Releasing
+
+Test locally first — the build-deploy loop is slow. Deploy only when a feature is complete.
+
+1. Ask whether a deploy is wanted; it is not automatic.
+2. Bump `version` in `pyproject.toml` (patch for fixes, minor for features).
+3. Move `[Unreleased]` entries into a dated section in `CHANGELOG.md`.
+4. Stage the changed files by name, commit, tag `vX.Y.Z`, `git push origin main --tags`.
+5. Gitea CI builds and pushes on the tag; Watchtower deploys.
+6. Verify: `curl http://192.168.86.149:8000/health`.

-
-### Deliverables
-
-1. **PydanticAI Integration** ✅
-   - PydanticAI → Ollama connection ✅
-   - Agent creation patterns ✅
-   - Streaming response handling ✅
-   - Error handling and retries ✅

-
-### 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

-- [ ] Implement structured recommendation output
-- [ ] Add registry query tool
-- [ ] Test with various request types
-
-#### Week 5-6: Integration
-- [ ] Build request preprocessing pipeline

-- [ ] 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.

-
----
-
-## Risk Management
-
-### High Risk Items
-1. **PydanticAI + Ollama integration complexity**
-   - Mitigation: Prototype early, iterate on connection layer
-
-2. **Multi-agent coordination complexity**
-   - Mitigation: Start simple, add coordination gradually
-
-3. **Model performance on homelab hardware**
-   - Mitigation: Model selection, quantization, optimization
-
-4. **Prompt engineering for personality consistency**
-   - Mitigation: Extensive testing, user feedback, iteration
-
-### Medium Risk Items
-- MCP protocol adoption and tooling maturity
-- Vector embedding quality for memory
-- Home automation integration variability
-- User authentication security
-
----
-
-## Next Steps
-
-1. **Priority**: Implement The Developer agent for code assistance
-2. **Integration**: Add Home Assistant integration for The Housekeeper
-3. **Calendar**: Integrate scheduling service for The Secretary
-4. **Ongoing**: Add more household staff as needed

+# 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 |

+- **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)

+# Steward Routing & Thinking — Findings
+
+**Outcome: no change shipped.** The Steward stays on `gemma4:e2b` with model
+thinking left at its default (on). Every alternative was measured and every one
+loses. This document exists so the experiment is not repeated on the same
+premise.
+
+Run 2026-08-08 with `scripts/benchmark_routing.py` and
+`scripts/fixtures/routing_fixtures.py` (40 labelled queries, one repeat per
+cell, temperature 0.3 as production sends).
+
+---
+
+## The premise was wrong
+
+The experiment was designed around an observation that the Steward pays ~300
+tokens per turn for reasoning that is generated and thrown away: it calls
+`/api/generate`, gemma4 reasons by default, and **no `thinking` field comes back
+in the response**. Disabling thinking therefore looked close to free.
+
+It is not. The reasoning is not discarded — it is emitted inline in `response`,
+and it is what produces a correct `DELEGATE:` line. Those tokens are the work,
+not waste. Suppressing them costs 12.5 points of routing accuracy.
+
+## Results
+
+| config | exact | under | over | tokens | latency | resident | predicted | co-resident with nomic |
+|---|---|---|---|---|---|---|---|---|
+| **e2b, thinking** *(production)* | **97.5%** | 2.5% | 0% | 361 | 5179 ms | 1778 MB | 7.8 GiB | yes |
+| e2b, `think: false` | 85.0% | 12.5% | 5.0% | 48 | 1435 ms | 1778 MB | 7.8 GiB | yes |
+| e4b, thinking | 100% | 0% | 0% | 192 | 4726 ms | 3089 MB | 10.6 GiB | **no** |
+| e4b, `think: false` | 97.5% | 2.5% | 0% | 52 | 2269 ms | 3089 MB | 10.6 GiB | **no** |
+
+`think: true` was also measured and landed within one fixture of the default on
+both models, so production's implicit thinking is the same thing as asking for
+it explicitly. Format compliance was 100% in every cell — a `DELEGATE:` line is
+always emitted.
+
+With 40 fixtures and one repeat, each result is worth 2.5 points, so the
+97.5-vs-100 gaps are single fixtures and inside the noise. The latency and token
+medians (40 calls each) and the e2b `think: false` degradation (6 failures with a
+consistent mechanism) are the parts worth trusting.
+
+## Why each alternative loses
+
+**`think: false` on e2b** — 85% exact, and the failures are not random. All three
+multi-capability fixtures under-route, each missing a second capability. Without
+reasoning the model names one capability and stops decomposing. It is not
+degraded across the board; it specifically stops handling compound requests,
+which is where a user would most notice the Butler quietly doing half the job.
+
+**e4b, either setting** — disqualified by memory, not by quality. Ollama predicts
+**10.6 GiB** for it at 16k context. Maximum available on this card is ~7.9 GiB
+(10.4 free − 2.0 GPU overhead − 0.46 minimum), so e4b *always* exceeds the budget
+and evicts every co-resident before loading. Observed directly: loading it threw
+out both `gemma4:e2b` and `nomic-embed-text`. Losing nomic means Tatlock memory
+and library-desk thrash on every embedding call. Note this is not caused by the
+2 GiB reservation — without it, available would be ~9.7 GiB, still under 10.6.
+
+**Lower `OLLAMA_CONTEXT_LENGTH`** — the obvious way to free headroom, and it does
+not work. Dropping 16384 → 2048, an 8× reduction, moved the prediction only from
+7.8 to 6.7 GiB. The prediction is dominated by weights and batch size, not KV
+cache. It would also truncate the Librarian's retrieved passages and webber's
+code context for a 14% saving that funds nothing.
+
+**Per-request `num_ctx`** — worse. A single request with a different `num_ctx`
+reloads the shared runner, which **drops the `keep_alive: -1` pin** (expiry fell
+from year-2318 to a 2-hour default) and evicts nomic. Three services share this
+Ollama, so mixed context sizes are a thrash generator, and it fails silently.
+
+**`OLLAMA_NUM_PARALLEL > 1`** — never viable here. e2b already predicts 7.8 GiB
+against ~7.9 available, so there is no room for a second slot at any context
+length. It is also set to 1 deliberately, to avoid batch overflow panics.
+
+## What the two axes actually control
+
+They do not interact, which is the useful part:
+
+- **Model choice** governs VRAM and co-residency. e2b 1778 MB, e4b 3089 MB.
+- **Think setting** governs tokens, latency and routing quality — and costs
+  **nothing** in VRAM. Verified: e2b is resident at 1778 MB with `think` unset,
+  true and false alike, because the KV cache is allocated for the full context at
+  load time and `think` is a per-request generation parameter.
+
+So the only real question is whether 313 tokens and 3.7 seconds are worth 12.5
+points of compound-query routing. On a turn that is already three sequential
+Ollama calls, they are.
+
+## Prerequisite: the extraction fix
+
+These numbers are only meaningful because `_extract_capabilities` was fixed first
+(commit `a905363`). It previously substring-matched capability *domains* across
+the Steward's entire response, so ordinary English in the `REASON:` line selected
+agents — "description" contains the housekeeper domain "script", "acknowledge"
+contains "knowledge" and "know".
+
+That made **prose length a routing input**. Benchmarking against it would have
+shown `think: false` improving routing purely because shorter output produces
+fewer accidental substring hits — a thinking policy derived from a parsing
+artefact. The `adversarial` fixture group is regression coverage for exactly this.
+
+## If this is revisited
+
+The constraint is the single 11 GB card, not the model. A second inference host
+(*forge*) removes it entirely, and e4b's 100% routing becomes reachable without
+evicting anything. Re-run then; on this card the answer is settled.
+
+`scripts/benchmark_routing.py` takes `--models`, `--think` and `--repeats`, and
+restores GPU residency on exit — including on SIGTERM, which the first version
+did not.

+# Decisions, Questions, Rejected
+
+This directory holds structured planning records that pql parses
+into pql.db. Each record is a `### [DQR]-N: Title` heading inside
+a markdown file. Files live in three per-type subdirectories:
+
+- `decisions/<domain>.md` — confirmed design decisions
+- `questions/<domain>.md` — open questions that may resolve into
+  decisions or rejected proposals
+- `rejected/<domain>.md` — rejected proposals (kept for the audit
+  trail)
+
+The parser infers domain from the filename stem and record type
+from the parent subdirectory.
+
+D-records that propose implementation work link to `initiative`-type
+tickets via `decision_ref`. Run `pql decisions show <id>
+--with-tickets` to inspect implementation status.
+
+## Recommended domains
+
+Start with this canonical set; create files as records land in
+each domain:
+
+- **architecture** — structural commitments (storage, layering,
+  languages, libraries)
+- **process** — team workflow (commits, branches, releases, reviews)
+- **design** — user-facing surface (UX, UI, public APIs)
+- **coding-conventions** — team-internal code shape (style, lint,
+  file layout)
+- **testing** — quality strategy (coverage, layers, gates)
+
+You might also want, project-permitting:
+
+- `accessibility` — if you ship user-facing software
+- `security` — if you handle user data or network surfaces
+- `licensing` — if you release open-source or commercial
+- `documentation` — if user-docs are non-trivial
+- `deployment` — if shipping is non-trivial
+- `performance` — if you have perf budgets / SLOs

+Benchmark Steward routing quality against model and thinking settings.
+
+Talks to Ollama directly. No Tatlock server, no agents, no tools, nothing is
+executed — the mutating fixtures ("turn on the lights", "update the wiki") only
+ever produce a routing decision. That makes this cheap and repeatable, and it
+isolates the question: does the Steward still pick the right capabilities when
+the model reasons less?
+
+The request body is byte-identical to StewardAgent._call_ollama, plus the
+`think` flag under test, so a cell labelled `unset` is exactly what production
+sends today.
+
+Three thinking settings, because "on vs off" hides the interesting case:
+
+    unset   what production sends now. gemma4 reasons by default, and the
+            response carries no `thinking` field, so those tokens are generated
+            and discarded.
+    true    reasoning requested explicitly and returned in `thinking`.
+    false   reasoning suppressed.
+
+Scoring is deliberately asymmetric. A missing capability under-routes and the
+Butler answers without a tool it needed; a spurious one over-routes, and that is
+a real agent call — a stray librarian is a multi-second web search on a query
+that asked for arithmetic. Over-routing is the predicted failure when thinking
+is off, so `forbid` violations are reported separately rather than folded into
+one accuracy number.

+Labelled queries for the Steward routing benchmark.
+
+Each fixture carries both `expect` and `forbid`:
+
+  expect   capabilities that must appear. Missing one is under-routing — the
+           Butler answers without a tool it needed.
+  forbid   capabilities that must not appear. Over-routing is not cosmetic: a
+           spurious librarian is a real multi-second web call, and a spurious
+           housekeeper can actuate hardware.
+
+`forbid` matters more than `expect` here, because over-recommendation is the
+predicted failure when model thinking is disabled and the Steward has less room
+to discriminate.
+
+The `adversarial` group deserves explanation. Until 2026-08-08 the extractor
+substring-matched capability *domains* across the Steward's whole response, so
+ordinary English in its REASON line selected agents: "description" contains the
+housekeeper domain "script", "acknowledge" contains "knowledge" and "know",
+"economy" contains the biographer domain "my". Those queries invite exactly that
+vocabulary. They now serve as an end-to-end regression: routing must depend on
+what the Steward *decided*, not on the words it happened to use while explaining.
+
+Expectations follow the routing rules stated in the Steward prompt itself
+(src/agents/steward/agent.py), not on what a capability could plausibly cover.

+Guard production's GPU residency across a benchmark run.
+
+Benchmarks swap models on the card production is serving from. Ollama evicts to
+make room, so a run leaves its own models resident and the production one gone:
+the next voice turn pays a ~36s cold load, and the pin that prevented it is
+silently lost. That happened on 2026-08-08 — a routing benchmark evicted
+gemma4:e2b and left gemma4:e4b behind, and only the monitoring noticing
+`unexpected_models` caught it.
+
+Snapshot before, restore after, and wire the restore to SIGTERM as well as the
+normal path. Python runs `finally` for SIGINT, which arrives as
+KeyboardInterrupt, but the default SIGTERM action terminates outright — so
+`timeout`, a systemd stop or a plain `kill` would skip the guard entirely.

+# Housekeeper system prompt - Optimized for Mistral-Nemo function calling
+HOUSEKEEPER_SYSTEM_PROMPT = """You are a strictly tool-based home automation assistant.
 
-Your role is to help users control and monitor their smart home through Home Assistant:
-- Lights, switches, and other devices
-- Scenes (pre-configured device states)
-- Scripts (automation sequences)
-- Automations (event-triggered rules)
+## CRITICAL: You Have NO Internal Knowledge
 
-## Your Personality
-- Efficient and practical
-- Safety-conscious (confirm destructive actions)
-- Proactive in suggesting optimizations
-- Clear about what actions you're taking
+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.
 
-## Your Tools
+## Entity ID Format
 
-### Discovery Tools
-- **list_areas**: See all rooms/areas configured in Home Assistant
-- **list_devices**: Find devices by type (domain) or location (area)
-- **get_device_state**: Check a device's current state and attributes
+Entity IDs follow the format: `domain.name`
+Examples: `light.kitchen`, `light.study_main`, `switch.coffee_maker`
 
-### Control Tools
-- **turn_on**: Turn on lights, switches, etc. (supports brightness/color for lights)
-- **turn_off**: Turn off devices
-- **toggle**: Flip a device's state
+The `entity_id` parameter MUST be the COMPLETE value including the domain prefix.
+WRONG: `entity_id="kitchen"`
+RIGHT: `entity_id="light.kitchen"`
 
-### Scene Tools
-- **list_scenes**: See available scene presets
-- **activate_scene**: Activate a scene (e.g., "movie night", "good morning")
+## Step-by-Step Process (ALWAYS FOLLOW)
 
-### Script Tools
-- **list_scripts**: See available automation scripts
-- **run_script**: Execute a script
+When asked to control devices in a room:
 
-### Automation Tools
-- **list_automations**: See all automations and their status
-- **toggle_automation**: Enable or disable an automation
+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
 
-### History Tools
-- **get_history**: Check a device's state history
+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
 
-## Best Practices
+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
 
-1. **Device Discovery First**: If the user asks about devices without being specific,
-   use list_devices to find what's available before acting.
+## Tool Parameter Names
 
-2. **Confirm State After Actions**: After turning something on/off, you can verify
-   with get_device_state if needed.
+- turn_on, turn_off, toggle: Use `entity_id` (NOT device_id, NOT id)
+- activate_scene: Use `scene_id`
+- run_script: Use `script_id`
 
-3. **Use Entity IDs**: Devices are identified by entity_id (e.g., light.living_room).
-   Always use the exact entity_id from list_devices.
+## What NOT To Do
 
-4. **Area-Aware**: When users say "living room lights", filter by area="living_room".
-
-5. **Safety**: For actions affecting multiple devices or automations, summarize
-   what you're about to do.
-
-## Common Patterns
-
-- "Turn on the lights" → list_devices(domain="light"), then turn_on each
-- "What's on?" → list_devices() and filter for state="on"
-- "Movie time" → Either activate_scene("scene.movie_night") or run_script if available
-- "Dim the bedroom" → turn_on("light.bedroom", brightness=64)
+- 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
-Your responses are returned to Tatlock (the butler) who will synthesize them into
-a final answer for the user. Keep this in mind:
-- Lead with confirmation of what you did or found
-- Be specific about which devices were affected
-- Include relevant state information
-- Note any issues or failures
-- Be concise - Tatlock will format the final response
+
+After completing actions, briefly confirm:
+- Which devices were affected (list the entity_ids)
+- Whether each action succeeded or failed
