-# BYK-RAG (Retrieval-Augmented Generation Module)
+# LLM Module
-The **BYK-RAG Module** is part of the Burokratt ecosystem, designed to provide **retrieval-augmented generation (RAG)** capabilities for Estonian government digital services. It ensures reliable, multilingual, and compliant AI-powered responses by integrating with multiple LLM providers syncing with knowledge bases, and exposing flexible configuration and monitoring features for administrators.
+The **LLM Module** is the LLM orchestration component of the
+[Bürokratt](https://github.com/buerokratt) ecosystem, providing reliable, multilingual, and compliant
+AI-powered responses for Estonian government digital services. It is a **multi-workflow orchestrator**:
+a tool classifier inspects every user query and routes it to the most appropriate workflow — answering
+from the knowledge base, calling backend services and APIs, handling conversation, or declining
+gracefully when a request is out of scope.
----
+## Overview
-## Features
+Rather than treating every request as a single retrieval problem, the LLM Module classifies intent and
+dispatches to one of several specialised workflows. Retrieval-Augmented Generation (RAG) is **one** of
+these workflows — alongside Service, Context, API-Tool, and Out-of-Domain handling. All workflows run
+over configurable, multi-provider LLMs, are protected by safety guardrails, and are fully traced for
+cost and quality.
-- **Configurable LLM Providers**
- - Support for AWS Bedrock, Azure AI, Google Cloud, OpenAI, Anthropic, and self-hosted open-source LLMs.
- - Admins can create "connections" and switch providers/models without downtime.
- - Models searchable via dropdown with cache-enabled indicators.
+### Key Features
-- **Enhanced Security with RSA Encryption**
- - LLM credentials encrypted with RSA-2048 asymmetric encryption before storage.
- - GUI encrypts using public key; CronManager decrypts with private key.
- - Additional security layer beyond HashiCorp Vault's encryption.
+- **Multi-workflow orchestration** — a tool classifier routes each query to the Service, Context,
+ **RAG**, API-Tool, or Out-of-Domain (OOD) workflow using hybrid dense + sparse (BM25) search.
+- **Configurable LLM providers** — Azure OpenAI, AWS Bedrock, Google Cloud, OpenAI, Anthropic, and
+ self-hosted models. Admins create "connections" and switch providers/models without downtime.
+- **Grounded, cited answers** — RAG responses are restricted to Central Knowledge Base content, with
+ clear citations and an "I don't know" fallback when confidence is low.
+- **Agentic API tool calling** — decomposes multi-intent queries and executes multi-endpoint API
+ workflows to fulfil actionable requests.
+- **Secure credential management** — provider credentials stored in HashiCorp Vault with an additional
+ RSA-2048 encryption layer.
+- **Safety guardrails** — NeMo Guardrails check input and output content with cost tracking.
+- **Observability** — Langfuse for traces/cost analytics and Grafana/Loki for logs.
-- **Knowledge Base Integration**
- - Continuous sync with central knowledge base (CKB).
- - Last sync timestamp displayed in UI.
- - LLMs restricted to answering only from CKB content.
- - "I don't know" payload returned when confidence is low.
+## Architecture
-- **Citations & Transparency**
- - All responses are accompanied with **clear citations**.
+The LLM Module sits behind the Ruuter API gateway and orchestrates retrieval, generation, and tool
+calling over a set of supporting data stores (Qdrant, Redis, PostgreSQL/ClickHouse, MinIO) and
+HashiCorp Vault for secrets.
-- **Analytics & Monitoring**
- - External **Langfuse dashboard** for API usage, inference trends, cost analysis, and performance logs.
- - Agencies can configure cost alerts and view alerts via LLM Alerts UI.
- - Logs integrated with **Grafana Loki**.

+**[docs/ARCHITECTURE.md](./docs/ARCHITECTURE.md)**.
-1. **Generate API keys from Langfuse UI** (Settings → Project → API Keys)
+## Tech Stack
+
+| Concern | Technology |
+| --- | --- |
+| Language / runtime | Python 3.12.10 |
+| Package manager | [uv](https://docs.astral.sh/uv/) |
+| API framework | FastAPI + Uvicorn (port `8100`) |
+| LLM pipelines | DSPy |
+| Safety | NeMo Guardrails |
+| Vector database | Qdrant |
+| Sessions & history | Redis |
+| Analytics store | PostgreSQL + ClickHouse (Langfuse) |
+| Object storage | MinIO (S3-compatible) |
+| Secrets | HashiCorp Vault |
+| Observability | Langfuse, Grafana, Loki |
+| API gateway | Ruuter |
+
+## Quick Start
+
+### Prerequisites
+
+- Docker and Docker Compose
+- [uv](https://docs.astral.sh/uv/) (for local development outside containers)
+
+### Run the stack
-2. **Copy the script to vault container:**
```bash
-docker cp store-langfuse-secrets.sh vault:/tmp/store-langfuse-secrets.sh
+# Start the full stack (orchestration service + data stores + tooling)
+docker compose up -d
+
+# Check the orchestration service health
+curl http://localhost:8100/health
```
-3. **Execute the script with your API keys:**
+### Environment configuration
+
+Configuration is supplied through environment files at the repository root:
+
+| File | Scope |
+| --- | --- |
+| `.env` | Shared infrastructure (storage, databases, Redis, Vault, feature flags) |
+| `.env.llm_orchestration_service` | LLM Orchestration Service |
+| `.env.gui` | Admin GUI |
+| `.env.notification` | Notification server |
+
+Feature flags such as `TOOL_CLASSIFIER_ENABLED`, `SERVICE_WORKFLOW_ENABLED`,
+`CONTEXT_WORKFLOW_ENABLED`, and `API_TOOL_CALLING_WORKFLOW_ENABLED` toggle individual workflows.
+
+## Components
+
+The orchestration service lives under `src/`. The main packages:
+
+| Component | Responsibility | Path |
+| --- | --- | --- |
+| Orchestration service & API | FastAPI app coordinating the pipeline | `src/llm_orchestration_service_api.py`, `src/llm_orchestration_service.py` |
+| Tool classifier & workflows | Intent detection and per-workflow execution (Service / Context / RAG / API-Tool / OOD) | `src/tool_classifier/` |
+| Contextual retrieval | Hybrid semantic + BM25 search with RRF fusion | `src/contextual_retrieval/` |
+| Vector indexer | Document ingestion and embedding into Qdrant | `src/vector_indexer/` |
+| API tool indexer | Indexing of API endpoints for tool calling | `src/api_tool_indexer/` |
+| Intent data enrichment | LLM-generated enrichment of intent data | `src/intent_data_enrichment/` |
+| Response generator | Grounded answer generation with citations | `src/response_generator/` |
+| Prompt refiner | Query refinement for better retrieval | `src/prompt_refine_manager/` |
+| Guardrails | NeMo Guardrails input/output safety | `src/guardrails/` |
+| LLM configuration | Provider management, Vault credentials, feature flags | `src/llm_orchestrator_config/` |
+| Optimization | DSPy-based tuning of guardrails, refiner, generator | `src/optimization/` |
+| Utilities | Redis, sessions, rate limiting, streaming, cost, logging | `src/utils/` |
+
+## Core Workflows
+
+The tool classifier routes each query to one of:
+
+- **Service** — maps the query to a backend service/intent ([docs](./docs/TOOL_CLASSIFIER_AND_SERVICE_WORKFLOW.md))
+- **Context** — greetings and conversation handling with Redis-backed history ([docs](./docs/CONTEXT_WORKFLOW_GREETING_DETECTION.md))
+- **RAG** — contextual retrieval then grounded generation ([docs](./docs/CONTEXTUAL_RETRIEVAL_FLOW.md))
+- **API-Tool** — agentic multi-endpoint API calling ([docs](./docs/API_TOOL_CALLING.md))
+- **OOD** — graceful fallback for out-of-domain queries
+
+Classification itself uses hybrid dense + sparse search — see
+[docs/HYBRID_SEARCH_CLASSIFICATION.md](./docs/HYBRID_SEARCH_CLASSIFICATION.md).
+
+## Documentation
+
+The full documentation catalogue lives in **[docs/README.md](./docs/README.md)**, covering
+architecture, retrieval, workflows, configuration/secrets, sessions, and the API reference.
+
+## Development

+
+### Storing Langfuse secrets
+
+Generate API keys in the Langfuse UI (**Settings → Project → API Keys**), then store them in Vault.
+
+For Docker Compose deployments, use the [`store-langfuse-secrets.sh`](./store-langfuse-secrets.sh)
+script:
+
+```bash
+# Copy the script into the vault container
+docker cp store-langfuse-secrets.sh vault:/tmp/store-langfuse-secrets.sh
+
+# Run it with your Langfuse keys

+
+## Troubleshooting
+
+| Symptom | Where to look |
+| --- | --- |
+| Service unhealthy | `curl http://localhost:8100/health`; `docker compose ps`; `docker compose logs llm-orchestration-service` |
+| Vault / credential errors | [docs/VAULT_SETUP_AND_USAGE.md](./docs/VAULT_SETUP_AND_USAGE.md) and [docs/VAULT_SECURITY_ARCHITECTURE.md](./docs/VAULT_SECURITY_ARCHITECTURE.md) |
+| Missing conversation history | Redis connectivity (`REDIS_HOST`/`REDIS_AUTH`); [docs/REDIS_SESSION_STORE.md](./docs/REDIS_SESSION_STORE.md) |
+| Retrieval returns nothing | Qdrant availability (port `6333`) and that indexing has run |
+| Logs & traces | Grafana/Loki for logs; Langfuse for request traces and cost |

+# API Reference
+
+This document is the consolidated HTTP API reference for the LLM Module. It covers the **LLM
+Connections** management endpoints, the **Inference Results** storage/retrieval endpoints, and the
+chatbot **Inquiry** endpoint exposed to the LLM Orchestration Service.
+
+> Routing note: the public-facing paths below are served through the Ruuter API gateway
+> (`ruuter-private` / `ruuter-public`), which proxies to the LLM Orchestration Service. See
+> [ARCHITECTURE.md](./ARCHITECTURE.md) for how requests flow through the system.

+## Part 7 — Multi-Intent Handling
+
+> **Status:** All phases complete. Phase 1 (intent detection + parallel search), Phase 2 (session model extension), Phase 3 (multi-endpoint agentic loop), Phase 4 (parallel API caller), Phase 5 (multi-response formatter), and Phase 6 (full wiring in workflow executor) are production-ready.
+
+### Overview
+
+A multi-intent query like *"What are the public holidays in Estonia and what is the current electricity price?"* produces a **diluted embedding** — the dense vector sits between two endpoints rather than close to either one. The cosine score lands in the ambiguous band (≥ `API_TOOL_MIN_THRESHOLD`, < `API_TOOL_HIGH_CONFIDENCE_THRESHOLD`) rather than producing a clean high-confidence hit.
+
+Phase 1 adds a **score-band gate** that intercepts these ambiguous results and passes the raw query to `IntentDecomposer`. If two or more distinct intents are detected, sub-queries are searched in parallel and the results are stored in the session for eventual multi-endpoint execution.
+
+---
+
+### Phase 1: Score-Band Gate + Intent Decomposer
+
+#### Gate Logic (`classifier.py` — `_try_api_tool_classification`)
+
+```
+cosine ≥ HIGH_CONFIDENCE_THRESHOLD → single path, existing code unchanged
+cosine in [MIN_THRESHOLD, HIGH_CONFIDENCE) → ambiguous band → IntentDecomposer
+cosine < MIN_THRESHOLD → no match → RAG fallback
+```
+
+The gate only fires when:
+- `FeatureFlags.MULTI_INTENT_ENABLED = true` (env: `MULTI_INTENT_ENABLED`, default `true`)
+- The top result was **not already LLM-validated** by the disambiguator (`llm_validated=False`)
+
+The `llm_validated` flag on `APIToolSearchResult` prevents double LLM calls: when the disambiguator has already selected a winner it sets `llm_validated=True`, so the IntentDecomposer gate is skipped for that result.
+
+#### Disambiguator Edge Case Fix
+
+When `APISemanticSearcher` runs LLM disambiguation and the disambiguator **rejects all candidates** (returns `winner_id=None`):
+
+- **Old behaviour:** return `[]` → classified as RAG/CONTEXT even when the query was multi-intent
+- **New behaviour:** if there were multiple medium-confidence candidates, return the top cosine result *without* `llm_validated=True` so the IntentDecomposer gate can run
+
+This is the key fix that allows multi-intent queries to reach `IntentDecomposer` instead of falling through to RAG.
+
+#### `IntentDecomposerModule` (`src/tool_classifier/intent_decomposer.py`)
+
+DSPy module — receives the **raw user query**
+
+| Output | Description |
+|---|---|
+| `mode` | `"single"` or `"parallel"` |
+| `sub_queries` | List of focused sub-queries when `mode=parallel`; empty for single |
+
+**Conservative by design:** returns `"single"` on any failure or ambiguity — never forces a parallel path.
+
+Run asynchronously via `asyncio.to_thread(self, user_query)` (calls `__call__`, not `forward`, to avoid a DSPy warning).
+
+Sub-query count is capped at `MULTI_API_MAX_ENDPOINTS = 3`.
+
+#### Parallel Sub-Query Search
+
+When `mode=parallel`, each sub-query is independently searched against `api_tool_collection` using `asyncio.gather`:
+
+```python
+results = await asyncio.gather(
+ *[self._api_searcher.search(q, ...) for q in sub_queries]
+)
+```
+
+Each search generates its own focused embedding — no dilution from the combined query.
+
+Results are **deduplicated by endpoint name** (a single endpoint matched by two sub-queries counts once). If fewer than 2 distinct endpoints are found after dedup, the parallel result is discarded and the classifier falls back to the single path.
+
+#### `ExecutionMode` Enum (`src/tool_classifier/enums.py`)
+
+```python
+class ExecutionMode(str, Enum):
+ SINGLE = "single"
+ PARALLEL = "parallel"
+```
+
+Inherits from `str` so values serialize cleanly to JSON. Always compare against the enum member (e.g. `== ExecutionMode.PARALLEL`), not a string literal.
+
+#### `ClassificationResult` metadata for parallel mode
+
+| Key | Type | Description |
+|---|---|---|
+| `execution_mode` | `ExecutionMode` | `SINGLE` or `PARALLEL` |
+| `matched_endpoint` | dict | Set for single mode |
+| `matched_endpoints` | list[dict] | Set for parallel mode — all deduplicated endpoints |
+
+---
+
+### Phase 2: Session Model Extension
+
+Defined in [src/models/session_models.py](../src/models/session_models.py).
+
+#### `EndpointSessionState` (new model)
+
+Tracks per-endpoint collection state within a parallel session:
+
+| Field | Type | Default | Description |
+|---|---|---|---|
+| `endpoint` | dict | required | Full endpoint payload |
+| `collected_params` | dict | `{}` | Params gathered for this endpoint so far |
+| `completed` | bool | `False` | Flipped to `True` when all required params for this endpoint have been collected; API execution happens later, gated on `AgenticLoopStatus.COMPLETED` at the loop level |
+
+#### Extended `APIToolSession` fields
+
+Three new fields added — all optional with safe defaults so **existing Redis sessions deserialize without error**:
+
+| Field | Type | Default | Description |
+|---|---|---|---|
+| `execution_mode` | str | `"single"` | `"single"` or `"parallel"` — drives which loop handles this session |
+| `parallel_endpoints` | list[EndpointSessionState] | `[]` | One entry per matched endpoint; empty in single mode |
+| `active_endpoint_index` | int | `0` | Reserved for future sequential endpoint-tracking logic; not currently read or written by the parallel workflow |
+
+The existing single-mode fields (`selected_endpoint`, `collected_params`, `turn_count`, etc.) are **completely unchanged**. Single-mode sessions have `execution_mode="single"` and `parallel_endpoints=[]`.
+
+#### Session creation in parallel mode (`api_tool_workflow.py`)
+
+When `context["execution_mode"] == ExecutionMode.PARALLEL`, the workflow captures all matched endpoints from context and populates `parallel_endpoints`:
+
+```python
+APIToolSession(
+ ...
+ execution_mode="parallel",
+ parallel_endpoints=[
+ EndpointSessionState(endpoint=e) for e in all_matched
+ ],
+)
+```
+
+
+
+---
+
+### Phase 3: Multi-Endpoint Agentic Loop
+
+Defined in [src/tool_classifier/multi_agentic_loop.py](../src/tool_classifier/multi_agentic_loop.py).
+
+`MultiEndpointAgenticLoop` replaces `AgenticLoop` for parallel sessions. It is stateless between HTTP requests — all mutable state is held in the `EndpointSessionState` list passed in on each call.
+
+**Key behaviours:**
+
+- **Merged schema:** All endpoint `params` schemas are merged and deduplicated by param name. A param shared across two endpoints is asked once and applied to both.
+- **One question per turn:** The loop generates a single clarifying question covering the next highest-priority missing param across all endpoints.
+- **Per-endpoint distribution:** After extraction, `_distribute_params()` copies each extracted value to every endpoint whose schema includes that param name.
+- **Completion tracking:** An endpoint is marked `completed=True` in its `EndpointSessionState` once all its required params are present. The loop returns `COMPLETED` only when every endpoint is completed.
+- **Turn limit:** Determined by `_compute_turn_limits(num_endpoints)`:
+ - Multi-intent (`num_endpoints > 1`): fixed `MULTI_INTENT_MAX_TURNS` (6).
+ - Single-intent (`num_endpoints == 1`): `min(3 × num_endpoints, MULTI_API_MAX_TURNS)` — scales with endpoint count, capped at 9.
+- **Continuation threshold:** Also from `_compute_turn_limits`:
+ - Multi-intent: fixed `MULTI_INTENT_CONTINUATION_TURN` (4).
+ - Single-intent: `num_endpoints + 1`.
+
+**`stream_run_turn` signature:**
+
+```python
+await multi_loop.stream_run_turn(
+ chat_id=chat_id,
+ user_message=request.message,
+ conversation_history=conversation_history,
+ endpoint_states=session.parallel_endpoints, # list[EndpointSessionState]
+ turn_count=session.turn_count,
+ awaiting_continuation=session.awaiting_continuation,
+ session_language=effective_session_language,
+)
+```
+
+Returns `(AgenticLoopResult, list[str])` — the result and pre-tokenised question tokens.
+
+---
+
+### Phase 4: Parallel API Caller
+
+Defined in [src/tool_classifier/multi_api_caller.py](../src/tool_classifier/multi_api_caller.py).
+
+`MultiAPICaller` wraps `APICaller` and fires all endpoint calls concurrently via `asyncio.gather`.
+
+**Key design decisions:**
+
+- Reuses the shared `APICaller` instance so per-URL circuit breaker state is preserved across single and batch invocations.
+- Expects a `"call_params"` key on each endpoint dict (distinct from the `"params"` schema list) to prevent the schema descriptor from being forwarded to the HTTP call.
+- A `MULTI_API_BATCH_TIMEOUT` (30 s) caps total wall-clock time. Pending tasks are cancelled on timeout and replaced with failure results — the caller always receives a fully-populated `MultiAPICallResult`.
+- Results are returned in the same order as the input endpoint list.
+- Partial failure is safe — a failed endpoint produces `APICallResult(success=False, error=)` without affecting other endpoints.
+
+**Usage:**
+
+```python
+call_payloads = [
+ {**state.endpoint, "call_params": state.collected_params}
+ for state in parallel_endpoints
+]
+multi_result = await MultiAPICaller(api_caller).call_all(
+ call_payloads, language=detected_language
+)
+```
+
+---
+
+### Phase 5: Multi-Response Formatter
+
+Defined in [src/tool_classifier/multi_response_formatter.py](../src/tool_classifier/multi_response_formatter.py).
+
+`MultiResponseFormatterModule` is a DSPy module that synthesises N API results into one unified natural-language answer.
+
+**DSPy Signature:** `MultiResponseFormatterSignature`
+
+| Input field | Description |
+|---|---|
+| `user_query` | The user's original first-turn question |
+| `api_results_block` | Formatted block of all API results (name, description, data) |
+| `num_results` | Number of results being synthesised |
+| `response_language` | `"English"`, `"Estonian"`, or `"Russian"` |
+| `custom_instructions` | Optional operator prompt overrides |
+
+| Output field | Description |
+|---|---|
+| `unified_answer` | Single coherent natural-language answer covering all endpoints |
+
+**Rules enforced by signature:**
+- Always write in `response_language` regardless of API data language.
+- Address every result — do not silently omit any endpoint.
+- Gracefully acknowledge failed or empty results without dwelling on them.
+- No raw JSON, no markdown headers, no follow-up invitation sentences.
+
+**Max input size:** 100 KB across all results combined (`_MAX_TOTAL_RESPONSE_BYTES`).
+
+**Methods:** `forward(user_query, api_results, detected_language)` (blocking) and `stream_forward_multi(user_query, api_results, detected_language)` (async token iterator).
+
+---
+
+### Phase 6: Full Wiring in `APIToolWorkflowExecutor`
+
+Defined in [src/tool_classifier/workflows/api_tool_workflow.py](../src/tool_classifier/workflows/api_tool_workflow.py).
+
+`_LoopStep` now has four possible `kind` values:
+
+| `kind` | Meaning |
+|---|---|
+| `"api_call"` | Single endpoint; all params collected; call API and format |
+| `"multi_api_call"` | Parallel endpoints; call all APIs concurrently and merge results |
+| `"question"` | Agentic loop needs more input; return question to user |
+| `"fallback"` | Nothing to do; caller falls back to RAG |
+
+**Parallel fast-path:** When all matched endpoints have no required params, `_compute_loop_step` skips session creation and returns a `"multi_api_call"` step immediately.
+
+**Streaming path (`_stream_multi_api_and_format`):**
+1. Builds `call_params`-keyed payloads for each `EndpointSessionState`.
+2. Calls `MultiAPICaller.call_all()` — all HTTP calls fire concurrently.
+3. Collects tokens from `MultiResponseFormatterModule.stream_forward_multi()` into a buffer.
+4. Runs output guardrails on the full buffered response before yielding any token to the client.
+5. Yields tokens one-by-one via `format_sse`, then yields `format_sse(chat_id, "END")`.
+
+**Blocking path (`_execute_multi_api_and_format`):**
+Same API call steps, then `asyncio.to_thread(formatter.forward, ...)` for the synthesis step.
+

+
+### Constants and Feature Flags
+
+Defined in [src/tool_classifier/constants.py](../src/tool_classifier/constants.py) and [src/llm_orchestrator_config/feature_flags.py](../src/llm_orchestrator_config/feature_flags.py):
+
+| Name | Value | Description |
+|---|---|---|
+| `MULTI_INTENT_ENABLED` | `true` (env override) | Feature flag — set `MULTI_INTENT_ENABLED=false` to disable the IntentDecomposer gate globally |
+| `MULTI_API_MAX_ENDPOINTS` | `3` | Hard cap on parallel sub-queries per request |
+| `MULTI_API_MAX_TURNS` | `9` | Absolute cap on turns for any parallel session (`min(3×N, 9)` per session) |
+| `MULTI_API_BATCH_TIMEOUT` | `30` | Seconds before the parallel HTTP batch is cancelled and partial results returned |
+| `API_TOOL_HIGH_CONFIDENCE_THRESHOLD` | `0.60` | Cosine score above which single-path is taken immediately |
+| `API_TOOL_MIN_THRESHOLD` | `0.40` | Minimum score for any match (below → RAG) |
+| `API_TOOL_INTENT_SWITCH_THRESHOLD` | `0.50` | Minimum cosine for the new match to trigger intent-switch detection |

+## Part 8 — ATC Response Cache
+
+### Overview
+
+The ATC Response Cache is a two-tier Redis cache that sits inside `_compute_loop_step()` in
+[src/tool_classifier/workflows/api_tool_workflow.py](../src/tool_classifier/workflows/api_tool_workflow.py).
+It is checked on every **new request** (no active session) before the agentic loop is created.
+
+Goal: avoid redundant API calls and agentic loop turns when the user is repeating or
+following up on a query that was already answered in the same conversation.
+
+Gated by `FeatureFlags.ATC_RESPONSE_CACHE_ENABLED` (`ATC_RESPONSE_CACHE_ENABLED` env var, default `true`).
+Setting it to `false` disables all cache reads and writes without touching any other ATC logic.
+
+---
+
+### Cache Architecture — Two Tiers
+
+#### Tier 1 — L1 Exact Response Cache
+
+```
+Key: atc:cache:{chat_id}:{api_name}:{param_hash}
+Value: raw API response JSON (dict or list)
+TTL: per-endpoint cache_ttl_seconds OR ATC_CACHE_DEFAULT_TTL_SECONDS (30 min)
+```
+
+Answers the question: *Has this exact conversation called this exact endpoint with these exact params before?*
+
+`param_hash` is a 16-character hex digest of the **normalised, sorted** param dict:
+- String values are stripped of whitespace
+- Purely numeric strings (`"2026"`) are cast to `int` before hashing
+- All-alpha strings (enum-like, e.g. `"GET"`, `"EE"`) are lowercased
+- Keys are sorted so order does not matter
+
+This means `{year: "2026", country: "EE"}` and `{country: "ee", year: 2026}` produce
+the **same hash** and hit the same cache entry.
+
+#### Tier 2 — L2 Last Call Context
+
+```
+Key: atc:last:{chat_id}
+Value: JSON list[LastCallContext]
+TTL: ATC_LAST_CALL_TTL_SECONDS (30 min, sliding — reset on every write)
+```
+
+Answers the question: *What was the last API call made in this conversation?*
+
+Stores a full `LastCallContext` per succeeded endpoint. Single-intent calls write a
+one-element list; multi-intent parallel calls write one entry per succeeded endpoint.
+The follow-up detector searches this list by `api_name` to find the relevant prior call.
+
+---
+
+### Data Model: `LastCallContext`
+
+Defined in [src/models/session_models.py](../src/models/session_models.py).
+
+| Field | Type | Description |
+|---|---|---|
+| `api_name` | str | Endpoint name (snake_case) that was called |
+| `endpoint` | dict | Full endpoint payload from Qdrant (params schema, URL, method, etc.) |
+| `collected_params` | dict | Parameter values that were passed to the API call |
+| `raw_response` | Any | Parsed API JSON (dict or list) as returned by `APICaller` |
+| `original_query` | str | User's first-turn query that triggered this API call |
+| `timestamp` | float | Unix timestamp of the call (for staleness reference) |
+
+---
+
+
+### Cache Write Points
+
+L1 and L2 are written **after** every successful API call, as a background
+`asyncio.create_task` so they never delay the user-facing response:
+
+**Single-intent (`_execute_api_and_format`)**
+After `api_result.success == True` and before the formatter:
+```
+set_l1(chat_id, endpoint["name"], collected_params, response_data, ttl)
+set_l2(chat_id, [LastCallContext(...)])
+```
+
+**Multi-intent (`_execute_multi_api_and_format` / `_stream_multi_api_and_format`)**
+After `multi_result` is received, one write per succeeded endpoint:
+```
+for each (endpoint_state, result) where result.success and endpoint.cacheable:
+ set_l1(chat_id, endpoint["name"], endpoint_state.collected_params, result.response_data, ttl)
+ append LastCallContext to contexts_list
+set_l2(chat_id, contexts_list) ← one write for all endpoints
+```
+
+---
+
+### Cache Read Logic in `_compute_loop_step`
+
+The cache block runs only when:
+- No active Redis session exists (fresh request, not mid-loop)
+- Not a parallel multi-intent query (`not all_matched`)
+- `endpoint.cacheable == True`
+- `ATC_RESPONSE_CACHE_ENABLED == True`
+
+```
+New request → no session → endpoint resolved
+ │
+ ▼
+ ── L1 check ──────────────────────────────────────────────────────────
+ get_l1(chat_id, endpoint["name"], pre_extracted_params)
+ │
+ ├─ HIT → _LoopStep(kind="cached_response", cache_source="L1")
+ │ formatter receives cached raw response — no API call, no loop
+ │
+ └─ MISS → continue to L2
+ │
+ ── L2 check ──────────────────────────────────────────────────────────
+ get_l2(chat_id) → find entry where api_name == endpoint["name"]
+ │
+ ├─ No match → fall through to normal agentic loop
+ │
+ └─ Match found → FollowUpDetectorModule (DSPy via asyncio.to_thread)
+ │
+ │ Inputs: user_query, previous_query, previous_params, params_schema
+ │
+ ├─ "response_question"
+ │ → _LoopStep(kind="cached_response", cache_source="L2",
+ │ cached_raw_response=matching.raw_response)
+ │ no API call; formatter answers from the previous response
+ │
+ ├─ "param_update"
+ │ merged = {**matching.collected_params, **updated_params}
+ │ missing = _missing_required_params(schema, merged)
+ │
+ │ missing == []
+ │ ├─ hashes equal (params unchanged)
+ │ │ → try L1 with matching.collected_params
+ │ │ hit → cached_response (L1)
+ │ │ miss → cached_response (L2 raw_response)
+ │ └─ hashes differ (genuinely new params)
+ │ → _LoopStep(kind="api_call", collected_params=merged)
+ │ API called directly — entire agentic loop skipped
+ │
+ │ missing != []
+ │ → context["seeded_params"] = merged
+ │ fall through to agentic loop — only asks for gaps
+ │
+ └─ "new_intent"
+ → ignore L2; fall through to normal agentic loop
+
+ On any FollowUpDetectorModule exception → fall through to normal loop (fail-open)
+```
+
+---
+
+### Component: `FollowUpDetectorModule`
+
+Defined in [src/tool_classifier/follow_up_detector.py](../src/tool_classifier/follow_up_detector.py).
+
+DSPy `Predict` module that classifies the relationship between the new user query
+and the previous API call. Run via `asyncio.to_thread` to avoid blocking the event loop.
+
+**Inputs:**
+
+| Input | Description |
+|---|---|
+| `user_query` | The new user message |
+| `previous_query` | The user's original question that triggered the last API call |
+| `previous_params` | JSON of param values from the last call |
+| `params_schema` | JSON of the endpoint's param schema |
+
+**Output — three possible values for `follow_up_type`:**
+
+| Value | Meaning | Action |
+|---|---|---|
+| `response_question` | User is asking about the data already returned | Pass L2 `raw_response` to formatter; no API call |
+| `param_update` | User wants the same endpoint with different/additional params | Merge new params into previous; go to API directly if complete, else seed the loop |
+| `new_intent` | Completely unrelated query | Ignore L2; run normal agentic loop from scratch |
+
+**Security:** `updated_params` from the LLM is validated against the endpoint's param
+schema — keys not in the schema are silently dropped to prevent injection.
+
+**Fail-open:** any exception returns `{follow_up_type: "new_intent", updated_params: {}}`
+so the user is never blocked.
+
+---
+
+### Param Seeding
+
+When the L2 `param_update` path finds that merged params are still incomplete,
+it sets `context["seeded_params"] = merged` before falling through to the agentic loop.
+
+`AgenticLoop.run_turn()` and `stream_run_turn()` accept an optional `seeded_params` argument.
+On turn 0, the seeds are merged into `collected_params` **before** any extraction runs:
+
+```python
+if turn_count == 0 and seeded_params:
+ collected_params = {**seeded_params, **collected_params}
+```
+
+The merge order means existing `collected_params` win — seeds cannot overwrite values
+that were already explicitly provided. The seeds are also stored directly in the new
+Redis session (`APIToolSession.collected_params = seeded_params`) so they survive
+across HTTP requests.
+
+**Effect:** the agentic loop starts with inherited values already populated and only
+generates a question for the genuinely missing params.
+
+---
+
+### L2 Invalidation on Intent Switch
+
+When an intent switch is detected in `ToolClassifier.classify()` (user mid-session for
+endpoint A sends a message that strongly matches endpoint B), both the session and the
+L2 key are cleaned up:
+
+```python
+await session_store.delete(request.chatId) # existing behaviour
+if FeatureFlags.ATC_RESPONSE_CACHE_ENABLED:
+ await ATCCacheStore().invalidate_l2(request.chatId)
+```
+
+`invalidate_l2` deletes only the `atc:last:{chat_id}` key. L1 keys are **not** deleted —
+they are param-hash-scoped and expire on their own TTL. Deleting L1 would provide no
+safety benefit and would waste valid cached data.
+
+---
+
+### Cache Constants and Feature Flag
+
+Defined in [src/tool_classifier/constants.py](../src/tool_classifier/constants.py) and
+[src/llm_orchestrator_config/feature_flags.py](../src/llm_orchestrator_config/feature_flags.py):
+
+| Name | Value | Description |
+|---|---|---|
+| `ATC_CACHE_KEY_PREFIX` | `atc:cache` | Redis key prefix for L1 entries |
+| `ATC_LAST_CALL_KEY_PREFIX` | `atc:last` | Redis key prefix for L2 entries |
+| `ATC_CACHE_DEFAULT_TTL_SECONDS` | `1800` | Default L1 TTL (30 min); overridable per endpoint via `cache_ttl_seconds` |
+| `ATC_LAST_CALL_TTL_SECONDS` | `1800` | L2 TTL (30 min, sliding) |
+| `ATC_RESPONSE_CACHE_ENABLED` | `true` (env) | Master kill-switch — disables all reads and writes when `false` |
+
+---
+
+### Cache Component Reference
+
+| Class / File | Responsibility |
+|---|---|
+| `ATCCacheStore` ([src/utils/atc_cache_store.py](../src/utils/atc_cache_store.py)) | All Redis operations for L1 and L2; param normalisation and hashing |
+| `FollowUpDetectorModule` ([src/tool_classifier/follow_up_detector.py](../src/tool_classifier/follow_up_detector.py)) | DSPy classifier for follow-up type detection |
+| `LastCallContext` ([src/models/session_models.py](../src/models/session_models.py)) | Pydantic model stored in L2 |
+| `_compute_loop_step` ([src/tool_classifier/workflows/api_tool_workflow.py](../src/tool_classifier/workflows/api_tool_workflow.py)) | Where L1 + L2 are read and routing decisions are made |
+| `_execute_api_and_format` / `_stream_api_and_format` | Where L1 + L2 are written after single-intent calls |
+| `_execute_multi_api_and_format` / `_stream_multi_api_and_format` | Where L1 + L2 are written after parallel calls |
+| `ToolClassifier.classify` ([src/tool_classifier/classifier.py](../src/tool_classifier/classifier.py)) | L2 invalidation on intent switch |
+
+---
+
+### End-to-End Cache Example
+
+```
+Turn 1 — "What are public holidays in Estonia in 2026?"
+ Agentic loop collects {countryIsoCode:"EE", validFrom:"2026-01-01", validTo:"2026-12-31"}
+ API called → 12 holidays returned
+ L1 written: atc:cache:{id}:get_national_holidays:{hash({EE,2026-01-01,2026-12-31})}
+ L2 written: atc:last:{id} = [LastCallContext{api_name="get_national_holidays", ...}]
+
+Turn 2 — "Same for Latvia?"
+ No session → L1 miss (country changed) → L2 hit
+ FollowUpDetectorModule → param_update, updated_params={countryIsoCode:"LV"}
+ merged = {countryIsoCode:"LV", validFrom:"2026-01-01", validTo:"2026-12-31"}
+ no missing params + hashes differ → api_call step
+ API called directly — zero agentic loop turns
+ L1 + L2 updated with new result
+
+Turn 3 — "Which of those is a bank holiday?"
+ No session → L1 miss → L2 hit
+ FollowUpDetectorModule → response_question
+ Formatter receives Latvia raw_response from L2 → answers from cached data
+ No API call, no loop
+
+Turn 4 — "What is the weather in Tallinn?"
+ Classifier: get_weather matched (different endpoint)
+ Intent switch → session_store.delete + invalidate_l2
+ Fresh session for get_weather starts with empty L1 and L2

+# Architecture
+
+This page describes how the **LLM Module** fits together, using the
+[C4 model](https://c4model.com/) to move from a high-level system view down to the internal
+components of the LLM Orchestration Service. Each level links out to the detailed flow documents
+that explain the behaviour in depth.
+
+> The LLM Module is a **multi-workflow orchestrator** for the Bürokratt / Estonian Government AI
+> assistant. A tool classifier inspects every user query and routes it to the most appropriate
+> workflow — **Service**, **Context**, **RAG**, **API-Tool**, or **Out-of-Domain (OOD)**.
+---
+
+## Level 1 — System Context
+
+The context diagram shows the LLM Module as a single system, the people who use it, and the external
+systems it depends on (LLM providers, the Central Knowledge Base, observability tooling).
+
+.png)
+
+**Key relationships**
+
+- **End users / chatbot** send natural-language queries and receive grounded, cited answers.
+- **Administrators** configure LLM connections, prompts, budgets, and view analytics.
+- **LLM providers** (Azure OpenAI, AWS Bedrock, OpenAI, Anthropic, Google Cloud, self-hosted) supply
+ chat and embedding models, selected per connection.
+- **Central Knowledge Base (CKB)** provides the source content that is indexed for retrieval.
+- **Observability** (Langfuse, Grafana/Loki) captures traces, costs, and logs.
+
+---
+
+## Level 2 — Containers
+
+The container diagram zooms into the deployable units of the system and the data stores they rely on.
+
+.png)
+
+**Containers & data stores**
+
+| Container / Store | Role |
+| --- | --- |
+| **GUI** | Admin web interface for connections, prompts, budgets, and analytics. |
+| **Ruuter (public/private)** | API gateway that routes and authorises requests to backend services. |
+| **LLM Orchestration Service** | FastAPI service (port `8100`) — the core that runs the workflows. |
+| **Notification Server** | Node service pushing real-time updates (e.g. cost alerts, streaming relay). |
+| **Qdrant** | Vector database for knowledge-base and API-tool embeddings. |
+| **Redis** | Conversation history, session state, and rate-limit counters. |
+| **PostgreSQL + ClickHouse** | Relational + columnar stores backing Langfuse analytics. |
+| **MinIO (S3)** | Object storage for datasets and documents. |
+| **HashiCorp Vault** | Encrypted storage for LLM provider credentials. |
+
+For how requests traverse the gateway and the orchestration service, see
+[API_REFERENCE.md](./API_REFERENCE.md).
+
+---
+
+## Level 3 — Components (LLM Orchestration Service)
+
+The component diagram opens up the LLM Orchestration Service to show its internal building blocks: the
+tool classifier, the per-workflow executors, the contextual retriever, response generation, and
+guardrails.
+
+.png)
+
+### Request lifecycle (high level)
+
+1. **Validation & safety** — input is sanitised and checked against guardrails.
+2. **Tool classification** — hybrid dense + sparse (BM25) search over indexed examples routes the
+ query to a workflow. See [HYBRID_SEARCH_CLASSIFICATION.md](./HYBRID_SEARCH_CLASSIFICATION.md).
+3. **Workflow execution** — one of:
+ - **Service** — maps the query to a backend service/intent.
+ See [TOOL_CLASSIFIER_AND_SERVICE_WORKFLOW.md](./TOOL_CLASSIFIER_AND_SERVICE_WORKFLOW.md).
+ - **Context** — greeting/conversation handling with Redis-backed history.
+ See [CONTEXT_WORKFLOW_GREETING_DETECTION.md](./CONTEXT_WORKFLOW_GREETING_DETECTION.md).
+ - **RAG** — contextual retrieval (hybrid search + RRF fusion) then grounded generation.
+ See [CONTEXTUAL_RETRIEVAL_FLOW.md](./CONTEXTUAL_RETRIEVAL_FLOW.md).
+ - **API-Tool** — agentic multi-endpoint API calling.
+ See [API_TOOL_CALLING.md](./API_TOOL_CALLING.md).
+ - **OOD** — graceful fallback for out-of-domain queries.
+4. **Generation & guardrails** — the response is generated with citations and re-checked before return.
+5. **Observability** — the full trace and cost are recorded in Langfuse; logs go to Loki.

+# LLM Connection Swapping Flow
+
+## Overview
+
+LLM connections use a **UUID-based Vault path** design where environment swaps are **pure database operations** with zero Vault I/O. Each connection stores its credentials in Vault once at a fixed path (`secret/llm/connections/{platform}/{vault_uuid}`), and switching which connection is "production" vs "testing" only updates the `environment` column in PostgreSQL.

+## Database Schema
+
+```sql
+-- Table: rag_search.llm_connections
+CREATE TABLE rag_search.llm_connections (
+ id SERIAL PRIMARY KEY,
+ vault_uuid UUID NOT NULL DEFAULT gen_random_uuid() UNIQUE,
+ connection_name TEXT,
+ llm_platform TEXT, -- e.g., "azure_openai", "aws_bedrock"
+ llm_model TEXT,
+ embedding_platform TEXT,
+ embedding_model TEXT,
+ environment TEXT, -- "production" or "testing"
+ connection_status TEXT, -- "active" or "inactive"
+ -- ... budget fields, timestamps, etc.
+);
+```
+
+**Key point:** `vault_uuid` is immutable and assigned at row creation. The `environment` column is the only thing that changes during a swap.
+
+## Vault Path Structure
+
+```
+secret/
+├── llm/
+│ └── connections/
+│ ├── azure_openai/
+│ │ ├── ← credentials for connection 1
+│ │ └── ← credentials for connection 2
+│ └── aws_bedrock/
+│ └──
+└── embeddings/
+ └── connections/
+ ├── azure_openai/
+ │ └──
+ └── aws_bedrock/
+ └──
+```
+
+Environment is **NOT** part of the Vault path. This is the core design decision — it means swapping environments never touches Vault.
+
+## Connection Swap Flow (Step by Step)
+
+### 1. User Initiates Swap (GUI → Ruuter)
+
+The user edits a "testing" connection and changes its environment to "production" via the GUI. This triggers `POST /llm-connections/edit`.
+
+### 2. Ruuter Orchestrates the Swap (`edit.yml`)
+
+```yaml
+# Step 1: Check if promoting testing → production
+check_deployment_environment:
+ condition: environment == "production" && existing.environment == "testing"
+ next: get_existing_production_connection
+
+# Step 2: Find current production connection
+get_existing_production_connection:
+ call: Resql → get-production-connection
+ next: update_existing_production_to_testing
+
+# Step 3: Demote current production to testing (DB only)
+update_production_connection:
+ call: Resql → update-llm-connection-environment
+ body: { connection_id: , environment: "testing" }
+ next: clear_llm_cache
+
+# Step 4: Invalidate LLM service cache
+clear_llm_cache:
+ call: POST http://llm-orchestration-service:8100/cache/clear
+ next: update_llm_connection
+
+# Step 5: Update the edited connection to production (DB only)
+update_llm_connection:
+ call: Resql → update-llm-connection
+ body: { connection_id: , environment: "production", ... }
+```
+
+**Total Vault operations: 0** — only PostgreSQL updates and a cache invalidation.
+
+### 3. Cache Invalidation (`POST /cache/clear`)
+
+The LLM orchestration service caches `vault_uuid` and `connection_id` in memory (via `ConnectionIdFetcher`). Without invalidation, it would keep using the old production connection's vault_uuid.
+
+```python
+# src/llm_orchestration_service_api.py
+@app.post("/cache/clear")
+async def clear_connection_cache():
+ fetcher = get_connection_id_fetcher()
+ fetcher.clear_cache() # Clears all cached connection_id + vault_uuid entries
+ return {"status": "ok"}
+```
+
+### 4. Next Request Resolves New Connection
+
+On the next `/orchestrate/stream` request:
+
+```
+Request arrives → _initialize_llm_manager(environment="production", connection_id=None)
+ ↓
+ConnectionIdFetcher.fetch_vault_uuid_sync("production")
+ ↓ (cache is empty after clear)
+POST Resql → get-production-connection → returns new production row with vaultUuid
+ ↓
+vault_uuid cached in memory for subsequent requests
+ ↓
+ConfigurationLoader(environment="production", connection_id=)
+ ↓
+SecretResolver._build_vault_path() → "llm/connections/{provider}/{vault_uuid}"
+ ↓
+VaultAgentClient.get_secret() → fetches credentials from Vault
+ ↓
+LLM initialized with new credentials
+```

+
+## Where Cache Clear is Triggered
+
+| Operation | File | Triggers `/cache/clear`? |
+|-----------|------|--------------------------|
+| Add new production connection (demotes existing) | `add.yml` | Yes |
+| Edit connection to promote testing → production | `edit.yml` | Yes |
+| Delete a connection | `delete.yml` | No (not needed — deleted connections aren't cached) |
+| Edit without environment change | `edit.yml` | No (no swap happening) |
+
+## Caching Behavior
+
+### ConnectionIdFetcher Cache (In-Memory)
+
+```python
+# Cache keys:
+# "production_connection_id" → int (DB row ID)
+# "production_vault_uuid" → str (UUID for Vault path)
+# "testing_connection_id" → int
+# "testing_vault_uuid" → str
+
+_connection_cache: Dict[str, int | str] = {}
+```
+
+- **Populated on:** First request after service start or cache clear
+- **Cleared by:** `POST /cache/clear` (called by Ruuter after swap)
+- **Thread-safe:** Uses `threading.Lock`
+
+### SecretResolver Cache (TTL-Based)
+
+```python
+# Cache key: vault_path string → CachedSecret (data + expires_at)
+# TTL: 5 minutes (configurable)
+_cache: Dict[str, CachedSecret] = {}
+```
+
+- **Populated on:** Successful Vault read
+- **Evicted after:** 5-minute TTL
+- **Background refresh:** Expired entries are refreshed asynchronously
+- **Not cleared by `/cache/clear`** — addressed by TTL expiry
+
+### Why Two Caches?
+
+1. **ConnectionIdFetcher cache** — Avoids repeated DB calls to resolve which connection is currently "production". Cleared instantly on swap.
+2. **SecretResolver cache** — Avoids repeated Vault reads for the same credentials. Not cleared on swap because the vault_uuid changes, so the new path is a cache miss anyway.
+
+## Testing vs Production Connection Resolution
+
+| Aspect | Production | Testing |
+|--------|-----------|---------|
+| `connection_id` in request | Optional (auto-resolved from DB) | Required (must be provided) |
+| DB lookup | `get-production-connection` SQL | Not needed (UUID in request) |
+| Vault path | `llm/connections/{provider}/{auto_resolved_uuid}` | `llm/connections/{provider}/{provided_uuid}` |
+| Caching | Cached in ConnectionIdFetcher | Not cached (provided per-request) |
+
+## Adding a New Connection (Vault Write)
+
+Vault is only written to during **connection creation**, not during swaps:
+
+```mermaid
+sequenceDiagram
+ participant GUI
+ participant Ruuter
+ participant Resql as Resql (DB)
+ participant CronMgr as CronManager
+ participant Vault
+
+ GUI->>Ruuter: POST /llm-connections/add
+ Ruuter->>Resql: INSERT into llm_connections (generates vault_uuid)
+ Resql-->>Ruuter: {id, vaultUuid, ...}
+
+ Note over Ruuter: If production: demote old, clear cache
+
+ Ruuter->>CronMgr: POST /vault/secret/create {vaultUuid, platform, credentials}
+ CronMgr->>CronMgr: build_vault_path → "secret/llm/connections/{platform}/{vaultUuid}"
+ CronMgr->>Vault: Write credentials to path
+ Vault-->>CronMgr: OK
+ CronMgr-->>Ruuter: Success
+```
+
+## Key Design Decisions
+
+1. **No environment in Vault paths** — Swapping is instantaneous (DB UPDATE only), no secret migration needed.
+2. **UUID generated by PostgreSQL** — `gen_random_uuid()` DEFAULT ensures it's assigned atomically at INSERT.
+3. **Cache invalidation via HTTP** — Ruuter calls `/cache/clear` after any swap to ensure the orchestration service picks up the new production connection on the next request.
+4. **Resql auto-converts snake_case to camelCase** — `vault_uuid` in PostgreSQL becomes `vaultUuid` in all JSON responses. All DSL/code must use `vaultUuid`.
+5. **Graceful degradation** — If Vault is unavailable, `SecretResolver` falls back to last-known-good cached credentials.
+
+## Troubleshooting
+
+| Symptom | Likely Cause | Fix |
+|---------|-------------|-----|
+| Old connection still used after swap | Cache not cleared | Verify `clear_llm_cache` step fires in Ruuter DSL; manually call `POST /cache/clear` |
+| `vault_uuid` is null in Ruuter | Using `vault_uuid` instead of `vaultUuid` | Resql converts to camelCase — always use `vaultUuid` in DSL |
+| "No production connection found" | DB has no row with `environment = 'production'` | Create a production connection via GUI |
+| Vault secret not found | Vault path mismatch | Verify CronManager `store_secrets_in_vault.sh` used same `vaultUuid` as DB |
+| Stale credentials after 5+ minutes | SecretResolver TTL expired but Vault is down | Check Vault connectivity; fallback cache serves last-known-good |

+## Redis-Backed Conversation History
+
+### Overview
+
+`ConversationHistoryStore` is a Redis-backed CRUD store (db=1) that holds per-session conversation data. It is the **canonical source of truth** for conversation history, replacing the GUI-provided `request.conversationHistory` when available.
+
+### Key Layout
+
+| Redis Key | Content | TTL |
+|-----------|---------|-----|
+| `conv:{chat_id}` | JSON list of up to 10 `ConversationRound` objects | 30 minutes (sliding) |
+| `conv:summary:{chat_id}` | Plain-text incremental summary of evicted rounds | 30 minutes (sliding) |
+
+Both keys share a sliding TTL: every write resets the expiry on both keys to keep them in sync.
+
+### History Capping and Eviction
+
+The store caps history at **10 rounds** (`_MAX_ROUNDS`). When appending a new round causes the count to exceed 10, the oldest rounds are trimmed. Trimmed (evicted) rounds are passed to an optional `summarizer` callable as a fire-and-forget background `asyncio.Task`, which merges them into the running summary using `IncrementalSummarySignature`.
+
+### `_build_history()` — History Resolution in the Workflow
+
+`ContextWorkflowExecutor._build_history()` resolves the history and pre-computed summary to pass to Phase 1:
+
+1. If `ConversationHistoryStore` is wired in, call `get_context(chat_id)` to retrieve rounds and the optional Redis summary.
+2. If rounds are present, flatten them into `{"authorRole", "message", "timestamp"}` dicts and return `(history, summary)`.
+3. If the store is absent, raises, or returns no rounds → fall back to `request.conversationHistory` with `summary=None`.
+
+The returned `pre_computed_summary` is forwarded to `detect_context_with_summary_fallback()` to skip an expensive LLM summarisation step when Redis already has one.
+
+### Optimistic Locking
+
+`save_round()` uses Redis `WATCH`/`MULTI`/`EXEC` (optimistic locking) to detect concurrent writes and retries up to 3 times on conflict.
+
+---
+
## Phase 1: Detection (Classify Only)
-### LLM Task
+### Three-Step Detection Flow
-Every query is checked against the **most recent 10 conversation turns** using a single LLM call (`detect_context()`). This phase **does not generate an answer** — it only classifies the query and extracts a relevant context snippet for Phase 2.
+Every query is processed by `detect_context_with_summary_fallback()`, which implements a three-step detection pipeline:
-The `ContextDetectionSignature` DSPy signature instructs the LLM to:
+**Step 1 — Recent turns check (`detect_context`)**
-1. Detect if the query is a greeting in any supported language
-2. Check if the query references something discussed in the last 10 turns
-3. If the query can be answered from history, extract the relevant snippet
-4. Do **not** generate the final answer here — detection only
+Runs `ContextDetectionSignature` via `dspy.ChainOfThought` against the **most recent 10 conversation turns**. This phase **does not generate an answer** — it only classifies the query and extracts a relevant context snippet for Phase 2.
+
+**Step 2 — Summary path (triggered when Step 1 cannot answer)**
+
+Triggered when `can_answer_from_context=False` AND one of the following is true:
+- Total history exceeds 10 turns (older turns exist), OR
+- Redis has a `pre_computed_summary` (covers evicted rounds beyond the current active window)
+
+Two sub-paths:
+- **Redis path**: Pre-computed summary is available → used directly (no LLM call, zero cost).
+- **On-demand path**: No pre-computed summary → older turns (beyond last 10) are summarised via `ConversationSummarySignature`.
+
+**Step 3 — Summary analysis (`_analyze_from_summary`)**
+
+Runs `SummaryAnalysisSignature` against the summary string to determine if the query can be answered from it. If so, the summary-derived answer is returned as `context_snippet` (with `answered_from_summary=True`) for Phase 2 generation.

### Greeting Response Generation
-Greeting detection is handled in **Phase 1 (`detect_context`)**, where the LLM classifies whether the query is a greeting and, if so, identifies the language and greeting type. This phase does **not** generate the final natural-language reply.
-In **Phase 2**, `ContextWorkflowExecutor` calls `get_greeting_response(...)`, which returns a response based on predefined static templates in `greeting_constants.py`, ensuring the reply is in the detected language. If greeting detection fails or the greeting type is unsupported, the query falls through to the next workflow layer instead of attempting LLM-based greeting generation.
+Greeting detection is handled in **Phase 1 (`detect_context`)**, where the LLM classifies whether the query is a greeting, identifies the `greeting_type`, and sets `is_greeting=True`. A message is only treated as a greeting if it contains **nothing beyond the greeting itself** — a greeting combined with a question is routed to RAG instead.
+
+In **Phase 2**, `ContextWorkflowExecutor` calls `get_greeting_response(greeting_type=..., language=...)`, which returns a static template from `greeting_constants.py`. The language is determined by `detect_language()` on the user query. No LLM call is made for greeting responses.
+
**Greeting response templates (`greeting_constants.py`):**
```python
GREETINGS_ET = {
- "hello": "Tere! Kuidas ma saan sind aidata?",
+ "hello": "Tere! Kuidas ma saan sind aidata?",

## Overview
-The custom prompt configuration system allows admins to configure prompts via UI that automatically apply to all response generation operations. Changes are cached with a 5-minute TTL and can be immediately refreshed when updated.
+The custom prompt configuration system allows admins to configure a single organisation-level prompt via the UI that automatically applies to user-facing answer generation. Changes are cached with a 5-minute TTL and can be immediately refreshed when updated.
+
+The same configured prompt is consumed by **two** workflows — the **RAG workflow** and the **API Tool Calling workflow** — through one shared `PromptConfigurationLoader`. The **Context workflow** does **not** apply custom prompts (greetings use static templates and history answers use their own signature). See [Where Custom Prompts Are Applied (by Workflow)](#where-custom-prompts-are-applied-by-workflow).
+
+---
+
+## Where Custom Prompts Are Applied (by Workflow)
+
+All consumers read the same prompt from the shared `PromptConfigurationLoader`
+(`src/utils/prompt_config_loader.py`, 5-minute TTL cache). They differ in **how** they inject it.
+
+| Workflow | Custom prompt applied? | Where / how |
+|---|---|---|
+| **RAG** | Yes | `ResponseGeneratorAgent` — the prompt is wrapped as `[SYSTEM INSTRUCTIONS]…[USER QUESTION]` and appended to the question for both streaming and non-streaming generation. |
+| **API Tool Calling** | Yes | `APIToolWorkflowExecutor._get_custom_instructions()` loads the raw prompt and passes it into parameter extraction and response formatting (see below). |
+| **Context** | No | `context_workflow.py` / `context_analyzer.py` do not load or apply the custom prompt. Greetings return static templates; history answers use `ContextResponseGenerationSignature` without injection. |
+| **Service** | No | The response is pre-formed text from Ruuter/DMapper — there is no LLM generation step to steer. |
+| **OOD** | No | Fixed localized out-of-scope message. |
+
+### RAG workflow
+
+- Source: [`src/llm_orchestration_service.py`](../src/llm_orchestration_service.py) → `_get_custom_instructions_for_response_generation()` builds the prefix
+ `"[SYSTEM INSTRUCTIONS]\n{prompt}\n\n[USER QUESTION]\n"` and passes it as
+ `ResponseGeneratorAgent(custom_instructions_prefix=…)`.
+- Application: [`src/response_generator/response_generate.py`](../src/response_generator/response_generate.py) applies it as
+ `augmented_question = f"{question}\n\n{custom_instructions_prefix}"` in both `forward()` and
+ `stream_response()`.
+- **Note:** despite the name `custom_instructions_prefix`, the string is **appended after** the
+ question (the wrapper text itself carries the `[USER QUESTION]` marker). It is **not** applied to
+ `PromptRefinerAgent`, which only optimises the query for retrieval.
+
+### API Tool Calling workflow
+
+- Source: [`src/tool_classifier/workflows/api_tool_workflow.py`](../src/tool_classifier/workflows/api_tool_workflow.py) → `_get_custom_instructions()` reads the **same** `prompt_config_loader`
+ (via `asyncio.to_thread`, fail-open to `""`). Unlike the RAG path, it passes the **raw** prompt
+ (no `[SYSTEM INSTRUCTIONS]` wrapper).
+- It is injected as a dedicated DSPy `custom_instructions` input field into:
+ - `ParamExtractionModule` ([`param_extractor.py`](../src/tool_classifier/param_extractor.py)) — steers how parameters are extracted from the user.
+ - `APIResponseFormatterModule` ([`api_response_formatter.py`](../src/tool_classifier/api_response_formatter.py)) — single-endpoint natural-language answer.
+ - `MultiResponseFormatterModule` ([`multi_response_formatter.py`](../src/tool_classifier/multi_response_formatter.py)) — multi-endpoint synthesis.
+- In the formatter/extractor signatures, a non-empty `custom_instructions` is followed with
+ **HIGHEST PRIORITY**, overriding defaults such as language policy, tone, and formatting.
+- Additionally, the workflow derives the response language from the prompt via
+ `_language_from_custom_instructions()` and merges any Redis conversation summary into the same
+ `custom_instructions` string before extraction.

-# LLM Config Module - HashiCorp Vault Integration
-
-## Overview
-
-The LLM Config Module integrates with HashiCorp Vault to securely store and manage API keys, endpoints, and other sensitive configuration data for various LLM providers (AWS Bedrock, Azure OpenAI, etc.). This integration replaces the traditional `.env` file approach with a more secure, centralized secret management system.
-
-## Architecture
-
-### Components
-
-1. **VaultSecretResolver** - Core component that interfaces with Vault
-2. **ConfigurationLoader** - Loads configuration and resolves secrets from Vault
-3. **LLMManager** - Main entry point that initializes with Vault-backed configuration
-4. **Connection Management** - Dynamic discovery of provider connections from Vault
-
-### Key Features
-
-- **Environment-Aware**: Automatically discovers and uses appropriate secrets based on environment (production/development/test)
-- **User-Independent**: No hardcoded user lists - dynamically discovers available connections
-- **Provider Discovery**: Automatically detects which LLM providers are available based on Vault contents
-- **Fallback Protection**: Graceful handling when Vault is unavailable (fails securely)
-
-## Vault Data Structure
-
-### Secret Storage Schema
-
-The Vault integration uses the KV v2 secrets engine with the following hierarchical structure:
-
-```
-secret/
-├── users/
-│ ├── user1/
-│ │ ├── conn_12345abc/
-│ │ │ ├── data/
-│ │ │ │ ├── provider: "aws_bedrock"
-│ │ │ │ ├── environment: "production"
-│ │ │ │ ├── aws_access_key_id: "AKIA..."
-│ │ │ │ ├── aws_secret_access_key: "..."
-│ │ │ │ ├── aws_region: "us-east-1"
-│ │ │ │ └── model_id: "anthropic.claude-3-sonnet-20240229-v1:0"
-│ │ └── conn_67890def/
-│ │ ├── data/
-│ │ │ ├── provider: "azure_openai"
-│ │ │ ├── environment: "development"
-│ │ │ ├── api_key: "sk-..."
-│ │ │ ├── endpoint: "https://myservice.openai.azure.com/"
-│ │ │ ├── deployment_name: "gpt-4"
-│ │ │ └── api_version: "2024-02-15-preview"
-│ └── user2/
-│ └── conn_11111xyz/
-│ └── data/
-│ ├── provider: "aws_bedrock"
-│ ├── environment: "production"
-│ └── ...
-```
-
-### Connection Metadata
-
-Each connection contains:
-
-- **Provider Type**: `aws_bedrock`, `azure_openai`, etc.
-- **Environment**: `production`, `development`, `test`
-- **Provider-specific secrets**: API keys, endpoints, regions, model IDs
-- **Connection ID**: Unique identifier for the connection
-
-## Development Container Setup
-
-### Current Container Configuration
-
-The project includes a development Vault container configured in `docker-compose.yml`:
-
-```yaml
-vault:
- image: hashicorp/vault:latest
- container_name: vault
- command: ["vault", "server", "-dev", "-dev-listen-address=0.0.0.0:8200", "-dev-root-token-id=myroot"]
- cap_add:
- - IPC_LOCK
- ports:
- - "8200:8200"
- environment:
- - VAULT_ADDR=http://0.0.0.0:8200
- - VAULT_API_ADDR=http://localhost:8200
- - VAULT_DEV_ROOT_TOKEN_ID=myroot
- - VAULT_DEV_LISTEN_ADDRESS=0.0.0.0:8200
- volumes:
- - vault-data:/vault/data
- networks:
- - bykstack
- restart: unless-stopped
- healthcheck:
- test: ["CMD", "vault", "status"]
- interval: 10s
- timeout: 5s
- retries: 5
-```
-
-### Starting the Development Environment
-
-1. **Start Vault Container**:
- ```bash
- docker-compose up vault -d
- ```
-
-2. **Verify Vault is Running**:
- ```bash
- curl http://localhost:8200/v1/sys/health
- ```
-
-3. **Access Vault UI**:
- - URL: http://localhost:8200
- - Token: `myroot`
-
-### Development Configuration
-
-For development, set these environment variables:
-
-```bash
-export VAULT_ADDR="http://localhost:8200"
-export VAULT_TOKEN="myroot"
-```
-
-## Usage Examples
-
-### Production Environment
-
-```python
-import os
-from llm_config_module import LLMManager
-
-# Set Vault connection details
-os.environ["VAULT_ADDR"] = "https://vault.company.com"
-os.environ["VAULT_TOKEN"] = "your-production-token"
-
-# Initialize LLM Manager - automatically discovers production providers
-manager = LLMManager(environment="production")
-
-# Get available providers (discovered from Vault)
-providers = manager.get_available_providers()
-print(f"Available providers: {list(providers.keys())}")
-
-# Use the LLM
-llm = manager.get_llm()
-response = llm.generate("Hello, world!")
-```
-
-### Development Environment
-
-```python
-# Development requires a specific connection ID
-manager = LLMManager(
- environment="development",
- connection_id="conn_12345abc" # Specific dev connection
-)
-
-llm = manager.get_llm()
-```
-
-### Dynamic Provider Discovery
-
-The system automatically discovers which providers are available:
-
-```python
-manager = LLMManager(environment="production")
-
-# Only providers with valid Vault secrets will be available
-if manager.is_provider_available(LLMProvider.AWS_BEDROCK):
- print("AWS Bedrock is configured and available")
-
-if manager.is_provider_available(LLMProvider.AZURE_OPENAI):
- print("Azure OpenAI is configured and available")
-```
-
-## Configuration Details
-
-### Vault Configuration (llm_config.yaml)
-
-```yaml
-vault:
- enabled: true
- url: "${VAULT_ADDR}"
- token: "${VAULT_TOKEN}"
- mount_point: "secret"
- secrets_engine: "kv-v2"
-
-providers:
- aws_bedrock:
- enabled: true # Will be dynamically determined from Vault
- model_id: "anthropic.claude-3-sonnet-20240229-v1:0"
- max_tokens: 1000
- temperature: 0.7
-
- azure_openai:
- enabled: true # Will be dynamically determined from Vault
- max_tokens: 1000
- temperature: 0.7
-```
-
-### Environment Variable Resolution
-
-The configuration supports environment variable substitution:
-
-- `${VAULT_ADDR}` - Vault server URL
-- `${VAULT_TOKEN}` - Vault authentication token
-
-## Production Considerations
-
-### Security Best Practices
-
-#### 1. Authentication & Authorization
-
-**🔒 Token Management**:
-```bash
-# Use short-lived tokens in production
-vault write auth/userpass/users/llm-service password="secure-password" policies="llm-read-policy"
-
-# Generate service token
-vault write -field=token auth/userpass/login/llm-service password="secure-password"
-```
-
-**🔒 Policy Configuration**:
-```hcl
-# llm-read-policy.hcl
-path "secret/data/users/*/conn_*" {
- capabilities = ["read"]
-}
-
-path "secret/metadata/users/*" {
- capabilities = ["list", "read"]
-}
-```
-
-#### 2. Network Security
-
-**🔒 TLS Configuration**:
-```hcl
-# vault.hcl (Production)
-listener "tcp" {
- address = "0.0.0.0:8200"
- tls_cert_file = "/etc/ssl/vault/vault.crt"
- tls_key_file = "/etc/ssl/vault/vault.key"
- tls_min_version = "tls12"
-}
-```
-
-**🔒 Network Isolation**:
-- Deploy Vault in private subnets
-- Use VPC endpoints for AWS services
-- Implement network ACLs and security groups
-- Enable Vault audit logging
-
-#### 3. High Availability Setup
-
-**🏗️ Raft Storage Backend**:
-```hcl
-storage "raft" {
- path = "/vault/data"
- node_id = "vault-1"
-
- retry_join {
- leader_api_addr = "https://vault-1.internal:8200"
- }
- retry_join {
- leader_api_addr = "https://vault-2.internal:8200"
- }
- retry_join {
- leader_api_addr = "https://vault-3.internal:8200"
- }
-}
-```
-
-**🏗️ Auto-Unseal** (recommended):
-```hcl
-seal "awskms" {
- region = "us-east-1"
- kms_key_id = "alias/vault-unseal-key"
-}
-```
-
-#### 4. Monitoring & Logging
-
-**📊 Health Checks**:
-```yaml
-# kubernetes health check
-livenessProbe:
- httpGet:
- path: /v1/sys/health
- port: 8200
- scheme: HTTPS
- initialDelaySeconds: 60
- timeoutSeconds: 5
-```
-
-**📊 Audit Logging**:
-```hcl
-audit "file" {
- file_path = "/vault/logs/audit.log"
-}
-```
-
-#### 5. Backup & Recovery
-
-**💾 Automated Snapshots**:
-```bash
-#!/bin/bash
-# backup-vault.sh
-vault operator raft snapshot save "vault-snapshot-$(date +%Y%m%d-%H%M%S).snap"
-aws s3 cp "vault-snapshot-*.snap" s3://vault-backups/
-```

-
-### Environment-Specific Configurations
-
-#### Production
-```yaml
-# Production values
-vault:
- url: "https://vault.company.com"
- token: "${VAULT_SERVICE_TOKEN}" # From secure secret management
-
-# Use IAM roles where possible
-providers:
- aws_bedrock:
- use_iam_role: true # Preferred over access keys
-```
-
-#### Staging
-```yaml
-vault:
- url: "https://vault-staging.company.com"
- token: "${VAULT_STAGING_TOKEN}"
-```
-
-#### Development
-```yaml
-vault:
- url: "http://localhost:8200"
- token: "myroot" # Development only
-```
-
-## Migration from .env Files
-
-### Step-by-Step Migration
-
-1. **Identify Current Secrets**:
- ```bash
- # List current .env variables
- grep -E "(API_KEY|SECRET|TOKEN)" .env
- ```
-
-2. **Create Vault Connections**:
- ```bash
- # Example: Migrate AWS credentials
- vault kv put secret/users/production/conn_aws_prod \
- provider="aws_bedrock" \
- environment="production" \
- aws_access_key_id="$AWS_ACCESS_KEY_ID" \
- aws_secret_access_key="$AWS_SECRET_ACCESS_KEY" \
- aws_region="us-east-1" \
- model_id="anthropic.claude-3-sonnet-20240229-v1:0"
- ```
-
-3. **Update Application Code**:
- ```python
- # Before (using .env)
- manager = LLMManager(config_path="config.yaml", environment="production")
-
- # After (using Vault)
- manager = LLMManager(environment="production") # Auto-discovers from Vault
- ```
-
-4. **Verify Migration**:
- ```python
- # Test that providers are discovered correctly
- providers = manager.get_available_providers()
- assert len(providers) > 0, "No providers discovered from Vault"
- ```
-
-## Testing
-
-### Unit Tests
-
-The integration includes comprehensive test coverage:
-
-- **Vault Integration Tests**: `test_integration_vault_llm_config.py`
-- **Provider-Specific Tests**: `test_aws.py`, `test_azure.py`
-- **Helper Functions**: `vault_test_helpers.py`
-
-### Running Tests
-
-```bash
-# Run all tests
-uv run pytest -v
-
-# Run only Vault integration tests
-uv run pytest tests/test_integration_vault_llm_config.py -v
-
-# Run provider-specific tests
-uv run pytest tests/test_aws.py tests/test_azure.py -v
-```
-
-### Test Helpers
-
-The `vault_test_helpers.py` provides utilities for test discovery:
-
-```python
-from tests.vault_test_helpers import (
- check_vault_available,
- get_available_providers_from_vault,
- should_skip_aws_test,
- should_skip_azure_test
-)
-
-# Conditionally skip tests based on Vault provider availability
-@pytest.mark.skipif(should_skip_aws_test(), reason="AWS not available in Vault")
-def test_aws_integration():
- # Test will only run if AWS Bedrock is configured in Vault
- pass
-```
-
-## Troubleshooting
-
-### Common Issues
-
-#### 1. Vault Connection Failures
-```python
-# Check Vault connectivity
-try:
- from rag_config_manager.vault import VaultClient
- vault = VaultClient()
- print(f"Vault available: {vault.is_vault_available()}")
-except Exception as e:
- print(f"Vault error: {e}")
-```
-
-#### 2. Provider Discovery Issues
-```python
-# Debug provider discovery
-import os
-os.environ["VAULT_ADDR"] = "http://localhost:8200"
-os.environ["VAULT_TOKEN"] = "myroot"
-
-manager = LLMManager(environment="production")
-providers = manager.get_available_providers()
-print(f"Discovered providers: {list(providers.keys())}")
-```
-
-#### 3. Authentication Errors
-- Verify `VAULT_TOKEN` is valid and not expired
-- Check token policies have required permissions
-- Ensure Vault server is accessible from application network
-
-#### 4. Secret Path Issues
-- Verify secret paths match the expected structure
-- Check that secrets exist in the correct mount point
-- Ensure proper KV v2 format is used
-
-### Logging
-
-Enable debug logging to troubleshoot issues:
-
-```python
-import logging
-logging.basicConfig(level=logging.DEBUG)
-
-# The LLM Config Module uses loguru for logging
-from loguru import logger
-logger.add("vault_debug.log", level="DEBUG")
-```
-
-## Best Practices Summary
-
-### ✅ Do:
-- Use production-grade Vault deployment with HA
-- Implement proper authentication (avoid root tokens)
-- Enable TLS in production
-- Use auto-unseal mechanisms
-- Implement comprehensive monitoring
-- Regular backup and recovery testing
-- Use IAM roles where possible instead of static keys
-- Rotate secrets regularly
-
-### ❌ Don't:
-- Use development mode Vault in production
-- Store root tokens in application code
-- Disable TLS in production environments
-- Skip audit logging
-- Use overly permissive policies
-- Store Vault tokens in environment files
-- Forget to implement proper secret rotation
-
-## Support & Maintenance
-
-### Vault Version Compatibility
-- **Minimum**: Vault 1.12+
-- **Recommended**: Vault 1.15+
-- **Tested With**: Vault 1.15.1
-
-### Dependencies
-- `rag_config_manager` - Vault client interface
-- `hvac` - HashiCorp Vault client library
-- `pydantic` - Data validation and settings management
-
-### Monitoring Endpoints
-- Health: `GET /v1/sys/health`
-- Metrics: `GET /v1/sys/metrics` (Prometheus format)
-- Status: `vault status` (CLI command)
-
-This integration provides a robust, secure, and scalable approach to managing LLM provider secrets using HashiCorp Vault, replacing traditional environment variable-based configuration with enterprise-grade secret management.

-# TestModel Page — Service Workflow Documentation
-
-This document traces the **service workflow** end-to-end through the **TestModel** UI page. It covers two scenarios:
-
-1. **Natural-language service detection** — the user types a free-text query that the system classifies as a service.
-2. **MCQ button-click** — the user clicks a choice button whose payload is a `#service` command, short-circuiting the NLU pipeline.

-## Flow 1: Natural-Language Service Detection
-
-### 1.1 Frontend — User Sends a Message
-
-The user selects an LLM connection from the dropdown and types a query (e.g., *"My keyboard is not working"*).
-
-**`TestModel/index.tsx` → `handleSend()`** (line 72):
-```tsx
-inferenceMutation.mutate({
- llmConnectionId: Number(testLLM.connectionId),
- message: testLLM.text,
-});
-```
-
-**`inference.ts` → `viewInferenceResult()`** (line 50):
-```ts
-const { data } = await apiDev.post(inferenceEndpoints.VIEW_TEST_INFERENCE_RESULT(), {
- connectionId: request.llmConnectionId,
- message: request.message,
-});
-```
-
-This POST goes to `/rag-search/inference/test` (via Ruuter proxy), which maps to the backend `/orchestrate/test` endpoint.
-
-### 1.2 API Layer — Request Mapping
-
-**`llm_orchestration_service_api.py` → `test_orchestrate_llm_request()`** (line 313):
-- Receives a `TestOrchestrationRequest` (only `message`, `environment`, optional `connectionId`).
-- Maps to a full `OrchestrationRequest` with defaults:
-
-```python
-full_request = OrchestrationRequest(
- chatId="test-session",
- message=request.message,
- authorId="test-user",
- conversationHistory=[],
- url="test-context",
- environment=request.environment,
- connection_id=str(request.connectionId) if request.connectionId is not None else None,
-)
-```
-
-- Calls `orchestration_service.process_orchestration_request(full_request)`.
-
-### 1.3 Orchestration Pipeline — Service Detection
-
-**`llm_orchestration_service.py` → `process_orchestration_request()`** (line 279):
-
-```
-STEP 0: Language detection → detect_language(request.message) → "en"
-
-STEP 0.1: Check request.message.startswith(SERVICE_STEP_PREFIXES)
- → FALSE (natural language) → skip, continue normally
-
-STEP 0.5: Query validation → validate_query_basic(request.message) → valid
-
-STEP 1: Component initialization → LLM manager, guardrails adapter
-
-STEP 2: Input guardrails check → allowed
-

- → Classification(workflow=SERVICE, confidence=0.92)

- the intent_collections Qdrant collection.
-
-STEP 4: route_to_workflow(classification, request, is_streaming=False)
- → Routes to ServiceWorkflowExecutor.execute_async()
-```
-
-### 1.4 ServiceWorkflowExecutor — `execute_async()`
-
-**`service_workflow.py` → `execute_async()`** (line 699):
-
-The executor uses **classification metadata** from hybrid search to decide how to proceed. There are three paths:
-
-| Condition | Path |
-|---|---|
-| `needs_llm_confirmation == False` | High-confidence match — run intent detection on the single top match only |
-| `needs_llm_confirmation == True` | Ambiguous — run intent detection on top-N candidates |
-| No metadata | Fall back to full discovery flow (`_log_request_details`) |
-
-#### Service Discovery (full flow)
-
-1. **`_call_service_discovery(chat_id)`** — calls `GET http://ruuter-public:8086/rag-search/services/get-services`
-2. Checks if `service_count > SERVICE_COUNT_THRESHOLD (10)` → triggers **semantic search** via Qdrant
-3. Otherwise uses the services list directly
-
-#### Intent Detection
-
-**`_process_intent_detection(services, request, chat_id, context, costs_metric)`**:
-1. Calls **`_detect_service_intent()`** → uses `IntentDetectionModule` (DSPy LLM) with:
- - The user query
- - The candidate services list
- - Conversation history
-2. Returns matched `service_id`, `confidence`, `entities`
-3. **`_validate_detected_service()`** — confirms the matched service exists in the active services list
-
-#### Entity Extraction & Validation
-
-```python
-service_metadata = self._extract_service_metadata(context, chat_id)
-# → {service_id, service_name, entities_dict, entity_schema, ruuter_type, is_common}
-
-validation_result = self._validate_entities(entities_dict, entity_schema, service_name, chat_id)
-# → checks missing, extra, empty entities
-
-entities_array = self._transform_entities_to_array(entities_dict, entity_schema)
-# → ordered list of entity values matching service schema
-```
-
-#### Service Endpoint Call
-
-```python
-endpoint_url = self._construct_service_endpoint(service_name, chat_id, is_common)
-# → "http://ruuter:8086/services/services/active/Klaviatuuri_probleemi_lahendamine"
-
-service_result = await self._call_service_endpoint(
- endpoint_url, http_method, entities_array, chat_id, author_id
-)
-```
-
-**`_call_service_endpoint()`** (line 523):
-1. Sends POST/GET to the Ruuter endpoint with payload `{chatId, authorId, input: entities_array}`
-2. Ruuter executes the DSL → DMapper produces the response
-3. Parses the response:
- - Unwraps `{"response": ...}` wrapper
- - Extracts `data[0].content` → text content
- - Extracts `data[0].buttons` → JSON string or list of `{title, payload}` objects
-4. Returns `{"content": str, "buttons": List[Dict]}`
-
-#### Build Response
-
-```python
-service_buttons = service_result["buttons"]
-buttons_list = [ChoiceButton(**b) for b in service_buttons if "title" in b and "payload" in b]
-
-return OrchestrationResponse(
- chatId=request.chatId,
- llmServiceActive=True,
- questionOutOfLLMScope=False,
- inputGuardFailed=False,
- content=service_content,
- buttons=buttons_list if buttons_list else None,
-)
-```
-
-### 1.5 API Layer — Response Conversion
-
-Back in `test_orchestrate_llm_request()` (line 382):
-
-```python
-test_response = TestOrchestrationResponse(
- llmServiceActive=response.llmServiceActive,
- questionOutOfLLMScope=response.questionOutOfLLMScope,
- inputGuardFailed=response.inputGuardFailed,
- content=response.content,
- buttons=response.buttons, # ← forwarded
- chunks=None,
-)
-```
-
-### 1.6 Frontend — Display Result
-
-**`TestModel/index.tsx`**:
-
-```tsx
-// onSuccess callback (line 51-54)
-setInferenceResult(data?.response);
-setPendingButtons(data?.response?.buttons ?? []);
-```
-
-- Response text is rendered inside `` (line 166-168)
-- MCQ buttons are rendered if `pendingButtons.length > 0` (line 173-186):
-
-```tsx
-{pendingButtons.map((btn) => (
-
-))}
-```
-
----
-
-## Flow 2: MCQ Button Click (Direct Step — Short-Circuit)
-
-### 2.1 Frontend — Button Click
-
-When the user clicks a button (e.g., *[Windows]*), `handleButtonClick()` is called (line 81):
-
-```tsx
-const handleButtonClick = (payload: string) => {
- if (!testLLM.connectionId) return;
- setPendingButtons([]);
- inferenceMutation.mutate({
- llmConnectionId: Number(testLLM.connectionId),
- message: payload, // e.g. "#service, /POST/services/active/Klaviatuuri_probleemi_lahendamine_mcq_1_0"
- });
-};
-```
-
-The button **payload** becomes the next message. The same API call (`/rag-search/inference/test` → `/orchestrate/test`) is made.
-
-### 2.2 Input Sanitizer Safety
-
-The `#service, /POST/...` payload goes through Pydantic's `validate_and_sanitize_message()` on `OrchestrationRequest.message` (line 64-88 of `request_models.py`). The `InputSanitizer.sanitize_message()` strips HTML tags and normalizes whitespace but leaves `#`, `,`, `/` characters intact. The payload passes through unchanged.
-
-### 2.3 Orchestration — `#service` Prefix Short-Circuit
-
-**`process_orchestration_request()`** (line 324-340):
-
-```python
-# STEP 0.1: Multi-step service prefix check (bypass NLU pipeline)
-if request.message.startswith(SERVICE_STEP_PREFIXES):
- logger.info(f"[{request.chatId}] #service prefix detected - direct step execution")
- executor = self._get_service_workflow_executor()
- direct_response = await executor.execute_direct_step(
- request=request,
- time_metric=time_metric,
- )
- if direct_response is not None:
- log_step_timings(time_metric, request.chatId)
- return direct_response
-```
-
-**`SERVICE_STEP_PREFIXES`** = `("#service,", "#common_service,")` from `constants.py`.
-
-**`_get_service_workflow_executor()`** (line 264):
-- Reuses the existing `tool_classifier.service_workflow` if a ToolClassifier has been initialized
-- Otherwise creates a lightweight `ServiceWorkflowExecutor(llm_manager=None, orchestration_service=self)` — no LLM is needed for direct steps
-
-### 2.4 ServiceWorkflowExecutor — `execute_direct_step()`
-
-**`service_workflow.py` → `execute_direct_step()`** (line 1000):
-
-1. **Parse**: `_parse_service_prefix(request.message)`
- - Input: `"#service, /POST/services/active/Klaviatuuri_probleemi_lahendamine_mcq_1_0"`
- - Splits off prefix → remainder: `/POST/services/active/...`
- - Extracts HTTP method: `POST`
- - Builds URL: `http://ruuter:8086/services/services/active/Klaviatuuri_probleemi_lahendamine_mcq_1_0`
- - Returns: `("POST", "http://ruuter:8086/services/services/active/...")`
-
-2. **Call endpoint**: `_call_service_endpoint(url, "POST", [], chat_id, author_id)`
- - `entities_array=[]` — no entities for MCQ steps
- - Same parsing as Flow 1 (extracts `content` + `buttons`)
-
-3. **Build response**: Same `OrchestrationResponse` construction as Flow 1
-
-### What Gets Skipped (Short-Circuit)
-
-| Skipped Step | Why |
-|---|---|
-| Query validation | Would reject `#service` as gibberish |
-| Component initialization | Expensive (LLM manager, Vault, guardrails) |
-| Input guardrails | Would block a machine-generated payload |
-| ToolClassifier.classify() | LLM call — unnecessary cost |
-| Intent detection LLM | Another LLM call — URL is already known |
-| Entity extraction | No natural language entities to extract |
-| Semantic search (Qdrant) | No need to find a service |
-
-### 2.5 Response & Loop
-
-The response follows the same path back through `test_orchestrate_llm_request()` → frontend.
-
-- If the response has `buttons` → frontend renders the next set of MCQ buttons
-- If the response has `buttons=null` → the MCQ flow is complete, only the final text answer is shown

+# Tool Classifier
+
+## Overview
+
+The **Tool Classifier** is the entry router of the LLM Module. For every incoming query it inspects the
+message (and conversation state) and dispatches it to exactly one **workflow** that knows how to answer.
+Retrieval-Augmented Generation (RAG) is just one of those workflows.
+
+This document gives a high-level understanding of the classifier itself — its routing model, key
+functions, and configuration. The **behaviour of each individual workflow is documented separately**;
+see [Related documentation](#related-documentation).
+
+Source: [`src/tool_classifier/`](../src/tool_classifier/). The classifier only runs when
+`TOOL_CLASSIFIER_ENABLED=true`; otherwise the service uses the RAG-only pipeline (backward compatible).
+
+---
+
+## Routing model
+
+Workflows are evaluated as a **layer-wise chain** (Strategy pattern). Each workflow either handles the
+query or returns `None` to fall through to the next layer. The order is defined by
+`WORKFLOW_LAYER_ORDER` in [`enums.py`](../src/tool_classifier/enums.py):
+
+```
+User query
+ │
+ ├─ active API-tool session for this chat_id? ──► short-circuit to API_TOOL_CALLING
+ │
+ ▼
+Layer 1: SERVICE → external Bürokratt service calls
+ ↓ (None)
+Layer 2: API_TOOL_CALLING → agentic external API tool calling
+ ↓ (None)
+Layer 3: CONTEXT → greetings + conversation-history answers
+ ↓ (None)
+Layer 4: RAG → knowledge-base retrieval + generation
+ ↓ (None)
+Layer 5: OOD → out-of-domain fallback (always answers)
+```
+
+If the classifier errors at any point, it falls back to RAG (`FALLBACK_TO_RAG_ON_ERROR = True`).
+
+---
+
+## How classification works
+
+`classify()` uses a **two-step search** to decide the workflow:
+
+1. **Dense search** — cosine similarity against the service collection for a relevance check.
+2. **Hybrid search** — dense + sparse (BM25) vectors fused with Reciprocal Rank Fusion (RRF) to
+ identify the best-matching service.
+
+High-confidence matches route straight to `SERVICE`; if no service matches, an API-tool search may route
+to `API_TOOL_CALLING`; otherwise the query falls through to `CONTEXT` / `RAG`. The full scoring scheme
+(thresholds, score-gap logic, sparse encoding) is documented in
+[HYBRID_SEARCH_CLASSIFICATION.md](./HYBRID_SEARCH_CLASSIFICATION.md).
+
+---
+
+## Key functions
+
+### `ToolClassifier` ([`classifier.py`](../src/tool_classifier/classifier.py))
+
+| Method | Purpose |
+| --- | --- |
+| `classify(query, conversation_history, language, request=None)` | Runs the two-step search and returns a `ClassificationResult` indicating the target workflow. Also handles the active-session short-circuit and intent-switch detection. |
+| `route_to_workflow(classification, request, is_streaming, ...)` | Executes the chosen workflow with layer-wise fallback. Returns an `OrchestrationResponse` (non-streaming) or an SSE `AsyncIterator[str]` (streaming). |
+| `aclose()` | Releases the shared Qdrant `httpx` client. |
+
+Internal helpers (not part of the public surface): `_dense_search()`, `_hybrid_search()`,
+`_try_api_tool_classification()`, and `_execute_with_fallback_async/streaming()`.
+
+### `BaseWorkflow` ([`base_workflow.py`](../src/tool_classifier/base_workflow.py))
+
+Every workflow executor inherits this contract:
+
+| Method | Purpose |
+| --- | --- |
+| `execute_async(request, context, time_metric=None)` | Non-streaming execution (`/orchestrate`, `/orchestrate/test`). Returns a response, or `None` to fall back to the next layer. |
+| `execute_streaming(request, context, time_metric=None)` | Streaming execution (`/orchestrate/stream`). Returns an SSE `AsyncIterator[str]`, or `None` to fall back. |
+
+The **return-`None` fallback** is the mechanism that powers the layer chain.
+
+### `ClassificationResult` ([`models.py`](../src/tool_classifier/models.py))
+
+| Field | Type | Description |
+| --- | --- | --- |
+| `workflow` | `WorkflowType` | Which workflow should handle the query. |
+| `confidence` | `float` (0.0–1.0) | Confidence in the classification. |
+| `metadata` | `dict` | Workflow-specific data passed to the executor (e.g. matched service/endpoint). |
+| `reasoning` | `str \| None` | Human-readable explanation of the decision. |
+
+---
+
+## Workflow executors
+
+Each `WorkflowType` maps to one executor under
+[`src/tool_classifier/workflows/`](../src/tool_classifier/workflows/). Detailed behaviour lives in the
+linked docs.
+
+| Workflow | Executor | Detailed documentation |
+| --- | --- | --- |
+| `SERVICE` | `service_workflow.py` | [TOOL_CLASSIFIER_AND_SERVICE_WORKFLOW.md](./TOOL_CLASSIFIER_AND_SERVICE_WORKFLOW.md) |
+| `API_TOOL_CALLING` | `api_tool_workflow.py` | [API_TOOL_CALLING.md](./API_TOOL_CALLING.md) |
+| `CONTEXT` | `context_workflow.py` | [CONTEXT_WORKFLOW_GREETING_DETECTION.md](./CONTEXT_WORKFLOW_GREETING_DETECTION.md) |
+| `RAG` | `rag_workflow.py` | [CONTEXTUAL_RETRIEVAL_FLOW.md](./CONTEXTUAL_RETRIEVAL_FLOW.md) |
+| `OOD` | `ood_workflow.py` | — (fixed out-of-domain response) |
+
+---
+
+## Configuration
+
+### Feature flags ([`feature_flags.py`](../src/llm_orchestrator_config/feature_flags.py))
+
+All are environment variables read at startup.
+
+| Flag | Default | Effect |
+| --- | --- | --- |
+| `TOOL_CLASSIFIER_ENABLED` | `false` | Master switch. When `false`, the service uses the RAG-only pipeline. |
+| `SERVICE_WORKFLOW_ENABLED` | `true` | Enables Layer 1 (Service). |
+| `API_TOOL_CALLING_WORKFLOW_ENABLED` | `true` | Enables Layer 2 (API tool calling). |
+| `CONTEXT_WORKFLOW_ENABLED` | `true` | Enables Layer 3 (Context). |
+| `MULTI_INTENT_ENABLED` | `true` | Enables the parallel multi-intent path (IntentDecomposer) in API tool calling. |
+| `ATC_RESPONSE_CACHE_ENABLED` | `true` | Enables the two-tier Redis response cache for API tool calling. |
+| `FALLBACK_TO_RAG_ON_ERROR` | `true` (constant) | Routes to RAG if the classifier raises. |
+
+> RAG and OOD have no flags — RAG is the core fallback and OOD is the final safety net.
+
+### Classification constants ([`constants.py`](../src/tool_classifier/constants.py))
+
+| Constant | Value | Purpose |
+| --- | --- | --- |
+| `QDRANT_COLLECTION` | `intent_collections` | Qdrant collection for Bürokratt services. |
+| `API_TOOL_COLLECTION` | `api_tool_collection` | Qdrant collection for registered API tool endpoints. |
+| `DENSE_MIN_THRESHOLD` | `0.5` | Below this cosine → not a service match. |
+| `DENSE_HIGH_CONFIDENCE_THRESHOLD` | `0.55` | At/above (with gap) → SERVICE without LLM confirmation. |
+| `DENSE_SCORE_GAP_THRESHOLD` | `0.05` | Required lead of the top service over the runner-up. |
+| `API_TOOL_MIN_THRESHOLD` | `0.40` | Below this → no API-tool match. |
+| `API_TOOL_HIGH_CONFIDENCE_THRESHOLD` | `0.60` | At/above → API-tool single-path immediately. |
+| `API_TOOL_INTENT_SWITCH_THRESHOLD` | `0.50` | Min cosine for a new endpoint to interrupt an active session. |
+
+See [HYBRID_SEARCH_CLASSIFICATION.md](./HYBRID_SEARCH_CLASSIFICATION.md) for how these thresholds combine,
+and [API_TOOL_CALLING.md](./API_TOOL_CALLING.md) for the multi-intent / caching constants.

-# Tool Classifier Extension - System Specification
-
-**Version**: 1.0
-**Date**: February 13, 2026
-**Status**: Design Specification
-
----
-
-## 1. Overview
-
-This document specifies the extension of the existing RAG Module with a **Tool Classifier** that implements layer-wise workflow routing. The classifier determines whether a user query should be handled by:
-
-1. **Service Workflow** - External service/API calls
-2. **Context Workflow** - Conversation history-based responses
-3. **RAG Workflow** - Knowledge base retrieval (existing)
-4. **OOD Response** - Out of domain fallback
-
-### 1.1 Current State
-
-**Existing Flow:**
-```
-User Query → Input Guardrails → Prompt Refiner → Contextual Retrieval → Response Generator → Output Guardrails
-```
-
-**Entry Points:**
-- `POST /orchestrate` - Non-streaming orchestration
-- `POST /orchestrate/test` - Testing environment with simplified input
-- `POST /orchestrate/stream` - Server-sent events streaming
-
-### 1.2 Proposed Extension
-
-**New Flow:**
-```
-User Query → Input Guardrails → Tool Classifier → [Service | Context | RAG | OOD]
- ↓
- Layer 1: Service Check
- ↓ (no match)
- Layer 2: Context Check
- ↓ (no match)
- Layer 3: RAG Retrieval
- ↓ (no chunks)
- Layer 4: OOD Response
-```
-
----
-
-## 2. Architecture Changes
-
-### 2.1 Component Integration
-
-The Tool Classifier will be integrated into the existing `LLMOrchestrationService` with minimal disruption:
-
-```python
-# Location: src/llm_orchestration_service.py
-
-def process_orchestration_request(self, request: OrchestrationRequest):
- """
- Modified orchestration pipeline with tool classifier.
-
- Pipeline:
- 1. Language Detection (existing)
- 2. Query Validation (existing)
- 3. Input Guardrails (existing, relocated)
- 4. Tool Classifier (NEW)
- 5. Workflow Routing (NEW)
- """
-
- # Existing: Step 0, 0.5
- detected_language = detect_language(request.message)
- validation_result = validate_query_basic(request.message)
-
- # Existing: Component initialization
- components = self._initialize_service_components(request)
-
- # Existing: Step 1 - Input Guardrails (RELOCATED before classifier)
- if components["guardrails_adapter"]:
- input_blocked = self.handle_input_guardrails(...)
- if input_blocked:
- return input_blocked
-
- # NEW: Step 2 - Tool Classifier
- classifier_result = self.tool_classifier.classify(
- query=request.message,
- conversation_history=request.conversationHistory,
- language=detected_language
- )
-
- # NEW: Step 3 - Workflow Routing
- if classifier_result.workflow == WorkflowType.SERVICE:
- return self._execute_service_workflow(request, classifier_result)
- elif classifier_result.workflow == WorkflowType.CONTEXT:
- return self._execute_context_workflow(request, classifier_result)
- elif classifier_result.workflow == WorkflowType.RAG:
- return self._execute_rag_workflow(request, classifier_result)
- else:
- return self._create_out_of_scope_response(request, detected_language)
-```
-
-### 2.2 New Components
-
-| Component | Location | Purpose |
-|-----------|----------|---------|
-| `ToolClassifier` | `src/tool_classifier/classifier.py` | Main classifier logic |
-| `ServiceWorkflowExecutor` | `src/tool_classifier/service_workflow.py` | Service discovery and triggering |
-| `ContextWorkflowExecutor` | `src/tool_classifier/context_workflow.py` | LLM-based conversation history analysis |
-| `IntentEntityExtractor` | `src/tool_classifier/intent_extractor.py` | LLM-based intent/entity detection |
-| `ServiceDiscoveryManager` | `src/tool_classifier/service_discovery.py` | Qdrant semantic search for services |
-| `IntentCollectionSync` | `src/tool_classifier/intent_sync_service.py` | Database → Qdrant synchronization |
-| `ContextAnalyzer` | `src/tool_classifier/context_analyzer.py` | LLM-based context availability checker |
-
-### 2.3 LLM Config Module Integration
-
-The existing LLM Config Module (`src/llm_config_module/`) is reused by the tool classifier for all LLM-based operations. No modifications to the core module are required.
-
-**Current LLM Config Module Capabilities:**
-- **Multi-Provider Support**: Azure OpenAI, AWS Bedrock, OpenAI, Anthropic
-- **Vault Integration**: Secure credential management via HashiCorp Vault
-- **Connection Management**: Dynamic LLM connection selection based on `connection_id` from requests
-- **Usage Tracking**: Token counting and cost calculation across providers
-
-**Tool Classifier LLM Usage:**
-
-| Workflow | LLM Operation | Config Usage | Temperature |
-|----------|---------------|--------------|-------------|
-| **Service (Layer 1)** | Intent & entity extraction | `llm_manager.call_llm_async()` | 0.0 (deterministic) |
-| **Context (Layer 2)** | Context availability check | `llm_manager.call_llm_async()` | 0.0 (deterministic) |
-| **RAG (Layer 3)** | Response generation | Existing integration | 0.7 (default) |
-| **OOD (Layer 4)** | No LLM call | N/A | N/A |
-
-**Integration Pattern:**
-
-```python
-# Tool classifier workflows use the same LLMManager instance
-class ToolClassifier:
- def __init__(self, llm_manager: LLMManager, ...):
- self.llm_manager = llm_manager # Reuse existing instance
-
- async def detect_intent(self, query: str, services: List[Service]):
- """Use LLM Config Module for intent detection."""
- response = await self.llm_manager.call_llm_async(
- prompt=INTENT_DETECTION_PROMPT.format(...),
- temperature=0.0, # Deterministic for classification
- max_tokens=200
- )
- return parse_intent(response)
-```
-
-**Configuration Reuse:**
-- Same connection selection logic (`connection_id` from `OrchestrationRequest`)
-- Same Vault credential retrieval
-- Same cost tracking pattern (`get_lm_usage_since()`)
-- Same error handling and retry logic
-- Same provider-specific implementations
-
-**No Changes Required**: The LLM Config Module is provider-agnostic and supports all tool classifier LLM calls out of the box.
-
----
-
-## 3. Layer 1: Service Workflow
-
-### 3.1 Workflow Logic
-
-When a user query is received, the system determines if it's a service-related request through the following steps:
-
-```
-1. Service Count Check → 2. Service Discovery → 3. Intent Detection → 4. Service Validation → 5. Entity Transformation → 6. Service Triggering
-```
-
-### 3.2 Step-by-Step Implementation
-
-#### Step 1: Service Count Check
-
-**Purpose**: Optimize performance based on service catalog size
-
-```python
-# Query: SELECT COUNT(*) FROM services WHERE current_state = 'active' AND deleted = FALSE
-
-if service_count <= 50:
- # Use all services for LLM context
- services = get_all_active_services()
-else:
- # Use semantic search for top 20 most relevant
- services = semantic_search_services(user_query, top_k=20)
-```
-
-**Database Query:**
-```sql
-SELECT COUNT(*) FROM public.services
-WHERE current_state = 'active' AND deleted = FALSE;
-```
-
-#### Step 2: Semantic Search (When Service Count > 50)
-
-**Tool**: Qdrant vector database
-**Collection**: `intent_collection`
-**Vector Dimension**: 3072 (text-embedding-3-large)
-
-**Search Configuration:**
-```python
-search_params = {
- "collection_name": "intent_collection",
- "query_vector": embed_query(user_query),
- "limit": 20,
- "score_threshold": 0.5, # Higher threshold for service matching
-}
-```
-
-**Output Format:**
-```json
-[
- {
- "service_id": "exchange-rate-001",
- "service_name": "ExchangeRateService",
- "description": "Provides currency exchange rates",
- "entities": ["fromCurrency", "toCurrency"],
- "score": 0.87
- },
- ...
-]
-```
-
-#### Step 3: LLM Intent Detection
-
-**Action**: Call LLM with user query and service context to extract:
-- `intent`: Service name to trigger
-- `entities`: Key-value pairs of extracted parameters
-
-**Prompt Template:**
-```python
-INTENT_DETECTION_PROMPT = """
-You are an intent classifier for government services. Analyze the user query and determine which service should handle the request.
-
-Available Services:
-{service_list}
-
-User Query: "{user_query}"
-
-Task:
-1. If the query matches a service, extract:
- - intent: The exact service name to trigger
- - entities: Key-value pairs of required parameters
-
-2. If NO service matches, respond with: {{"intent": null, "entities": null}}
-
-Response Format (JSON only, no explanation):
-{{"intent": "ServiceName", "entities": {{"param1": "value1", "param2": "value2"}}}}
-"""
-```
-
-**Expected LLM Response:**
-```json
-{
- "choices": [
- {
- "message": {
- "content": "{\"intent\": \"ExchangeRateService\", \"entities\": {\"fromCurrency\": \"EUR\", \"toCurrency\": \"USD\"}}"
- }
- }
- ]
-}
-```
-
-**Parsing Logic:**
-```python
-# Parse LLM response
-content = response["choices"][0]["message"]["content"]
-parsed = json.loads(content)
-
-if parsed["intent"] is None:
- # No service match - move to Layer 2 (Context Workflow)
- return WorkflowType.CONTEXT
-```
-
-#### Step 4: Service Validation
-
-**Action**: Validate the detected service against the database
-
-**Validation Query:**
-```sql
-SELECT service_id, name, ruuter_type, endpoints, structure, entities
-FROM public.services
-WHERE service_id = %(detected_service_id)s
- AND current_state = 'active'
- AND deleted = FALSE;
-```
-
-**Validation Checks:**
-- Service exists in database
-- `current_state = 'active'`
-- `deleted = FALSE`
-
-**Failure Handling:**
-```python
-if not service_exists or not service_active:
- logger.warning(f"Service validation failed: {detected_service_id}")
- # Fallback to Layer 2 (Context Workflow)
- return WorkflowType.CONTEXT
-```
-
-#### Step 5: Entity Transformation
-
-**Purpose**: Convert LLM entity object to array format for service payload
-
-**Input (from LLM):**
-```json
-{
- "fromCurrency": "EUR",
- "toCurrency": "USD"
-}
-```
-
-**Output (for service call):**
-```json
-["EUR", "USD"]
-```
-
-**Transformation Logic:**
-```python
-def transform_entities(entities: Optional[Dict[str, str]],
- entity_order: List[str]) -> List[str]:
- """
- Transform entity dictionary to ordered array.
-
- Args:
- entities: LLM-extracted entity key-value pairs
- entity_order: Expected entity order from service schema
-
- Returns:
- Ordered list of entity values
- """
- if not entities or entities is None:
- return []
-
- # Maintain order defined in service schema
- return [entities.get(key, "") for key in entity_order]
-```
-
-**Example:**
-```python
-# Service schema defines: entities = ["fromCurrency", "toCurrency"]
-transform_entities(
- {"fromCurrency": "EUR", "toCurrency": "USD"},
- ["fromCurrency", "toCurrency"]
-)
-# Output: ["EUR", "USD"]
-```
-
-#### Step 6: Service Triggering
-
-**Purpose**: Call the external service endpoint with formatted payload
-
-**URL Construction:**
-```python
-# From database field 'endpoints'
-base_url = "http://ruuter:8086" # From environment or service config
-service_endpoint = f"{base_url}/services/active{service_name}"
-
-# Example: http://ruuter:8086/services/activeExchangeRateService
-```
-
-**HTTP Method:**
-```python
-# Retrieved from database field 'ruuter_type'
-method = service.ruuter_type # 'GET' or 'POST' (ENUM)
-```
-
-**Payload Format:**
-```json
-{
- "input": ["EUR", "USD"],
- "authorId": "user-67890",
- "chatId": "chat-12345"
-}
-```
-
-**Implementation:**
-```python
-async def trigger_service(
- service: ServiceRecord,
- entities: List[str],
- request: OrchestrationRequest
-) -> Dict[str, Any]:
- """
- Trigger external service via Ruuter.
-
- Args:
- service: Validated service record from database
- entities: Transformed entity array
- request: Original orchestration request
-
- Returns:
- Service response or error
- """
- url = f"{RUUTER_BASE_URL}/services/active{service.name}"
- payload = {
- "input": entities,
- "authorId": request.authorId,
- "chatId": request.chatId
- }
-
- try:
- if service.ruuter_type == "GET":
- response = await http_client.get(url, params=payload, timeout=10)
- else: # POST
- response = await http_client.post(url, json=payload, timeout=10)
-
- response.raise_for_status()
- return response.json()
-
- except httpx.TimeoutException:
- logger.error(f"Service timeout: {service.service_id}")
- raise ServiceTimeoutError()
- except httpx.HTTPStatusError as e:
- logger.error(f"Service error: {e.response.status_code}")
- raise ServiceExecutionError()
-```
-
-**Response Handling:**
-
-**Non-Streaming:**
-```python
-service_response = await trigger_service(service, entities, request)
-formatted_content = format_service_response(service_response)
-
-# Apply output guardrails
-if guardrails_adapter:
- output_check = await guardrails_adapter.check_output_async(formatted_content)
- costs_metric["output_guardrails"] = output_check.usage
-
- if not output_check.allowed:
- logger.warning(f"Service response blocked by guardrails: {output_check.reason}")
- return create_guardrail_violation_response(request)
-
-# Return validated service response
-return OrchestrationResponse(
- chatId=request.chatId,
- llmServiceActive=True,
- questionOutOfLLMScope=False,
- inputGuardFailed=False,
- content=formatted_content
-)
-```
-
-**Streaming:**
-```python
-service_response = await trigger_service(service, entities, request)
-formatted_content = format_service_response(service_response)
-
-# Apply output guardrails validation
-if guardrails_adapter:
- output_check = await guardrails_adapter.check_output_async(formatted_content)
- costs_metric["output_guardrails"] = output_check.usage
-
- if not output_check.allowed:
- logger.warning(f"Service response blocked by guardrails")
- yield format_sse(request.chatId, OUTPUT_GUARDRAIL_VIOLATION_MESSAGE)
- yield format_sse(request.chatId, "END")
- return
-
-# Stream validated response token-by-token
-for token in split_into_tokens(formatted_content, chunk_size=5):
- yield format_sse(request.chatId, token)
- await asyncio.sleep(0.01) # Maintain streaming UX
-
-yield format_sse(request.chatId, "END")
-```
-
-### 3.3 Failure Scenarios
-
-| Scenario | Action |
-|----------|--------|
-| No intent detected | Move to Layer 2 (Context Workflow) |
-| Service validation failed | Move to Layer 2 (Context Workflow) |
-| Service call timeout | Return `SERVICE_TIMEOUT_ERROR` message |
-| Service returns error | Return `SERVICE_EXECUTION_ERROR` message |
-| Entity extraction incomplete | Attempt service call with partial entities, or fallback to Layer 2 |
-| Output guardrails blocked | Return `OUTPUT_GUARDRAIL_VIOLATION_MESSAGE` or fallback to Layer 2 |
-
-### 3.4 Output Guardrails for Service Responses
-
-**Why Service Responses Need Guardrails:**
-- External services may return PII (personal identifiable information)
-- Service errors could expose sensitive system details
-- Third-party API responses are untrusted content
-- Ensures consistent safety across all workflows
-
-**Integration Pattern:**
-
-Both non-streaming and streaming modes validate service responses before sending to users:
-
-```python
-# Get service response
-service_response = await trigger_service(...)
-
-# Apply output guardrails (validation-first)
-if guardrails_adapter:
- output_check = await guardrails_adapter.check_output_async(service_response)
- if not output_check.allowed:
- # Blocked - return error or fallback
- return create_guardrail_violation_response(request)
-
-# Validated - return/stream to user
-return/stream service_response
-```
-

-
-## 4. Layer 2: Context Workflow
-
-### 4.1 Workflow Logic
-
-If Layer 1 fails (no service match), use LLM to determine if the query is a greeting or can be answered from conversation history.
-
-**Trigger Conditions:**
-- No service intent detected in Layer 1
-- Query is a greeting (hello, hi, good morning, etc.) **OR**
-- Conversation history exists (at least 1 previous turn) and query references it
-
-### 4.2 Greeting Detection
-
-Greetings and conversational pleasantries are handled by the Context Workflow to provide natural, friendly responses without triggering service discovery or RAG retrieval.
-
-**Greeting Patterns (Multilingual):**
-
-```python
-# Estonian greetings
-ESTONIAN_GREETINGS = [
- "tere", "tervist", "tere hommikust", "tere päevast", "tere õhtust",
- "hei", "hommikust", "õhtust", "päevast", "nägemist",
- "tsau", "moi", "moikka"
-]
-
-# English greetings
-ENGLISH_GREETINGS = [
- "hello", "hi", "hey", "good morning", "good afternoon", "good evening",
- "greetings", "howdy", "morning", "afternoon", "evening"
-]
-
-# Farewell patterns
-FAREWELL_PATTERNS = [
- "goodbye", "bye", "see you", "talk to you later", "ttyl",
- "nägemist", "head aega", "kuni", "tsau"
-]
-```
-
-**LLM-Based Greeting Detection:**
-
-Instead of rigid pattern matching, the LLM analyzes whether the query is a greeting or conversational message:
-
-```python
-async def detect_greeting(
- query: str,
- llm_manager: LLMManager,
- language: str
-) -> GreetingResult:
- """
- Use LLM to detect if query is a greeting/conversational message.
-
- Args:
- query: User's message
- llm_manager: LLM manager instance
- language: Detected language (et/en)
-
- Returns:
- GreetingResult with is_greeting flag and optional response
- """
- prompt = GREETING_DETECTION_PROMPT.format(
- user_query=query,
- language=language
- )
-
- response = await llm_manager.call_llm_async(
- prompt=prompt,
- temperature=0.0,
- max_tokens=150
- )
-
- content = response["choices"][0]["message"]["content"]
- result = json.loads(content)
-
- return GreetingResult(
- is_greeting=result["is_greeting"],
- greeting_type=result.get("greeting_type"), # 'hello', 'goodbye', 'thanks', etc.
- suggested_response=result.get("suggested_response")
- )
-```
-
-**Greeting Detection Prompt:**
-
-```python
-GREETING_DETECTION_PROMPT = """
-You are a greeting classifier. Determine if the user's message is a greeting, farewell, or conversational pleasantry.
-
-User Message: "{user_query}"
-Language: {language}
-
-Task:
-1. Identify if this is a greeting/conversational message (hello, hi, goodbye, thanks, etc.)
-2. If YES: Classify the type and suggest an appropriate response
-3. If NO: Indicate it's not a greeting
-
-Response Format (JSON only):
-{{
- "is_greeting": true/false,
- "greeting_type": "hello" | "goodbye" | "thanks" | "casual" | null,
- "suggested_response": "friendly response in same language" | null
-}}
-
-Examples of greetings:
-- "Tere!" → {"is_greeting": true, "greeting_type": "hello"}
-- "Good morning" → {"is_greeting": true, "greeting_type": "hello"}
-- "Thanks for your help" → {"is_greeting": true, "greeting_type": "thanks"}
-- "What are digital signatures?" → {"is_greeting": false}
-"""
-```
-
-**Response Generation:**
-
-```python
-if greeting_result.is_greeting:
- # Use LLM-suggested response or fallback to predefined messages
- response = greeting_result.suggested_response or get_default_greeting_response(
- greeting_type=greeting_result.greeting_type,
- language=language
- )
-
- return OrchestrationResponse(
- chatId=request.chatId,
- llmServiceActive=True,
- questionOutOfLLMScope=False,
- inputGuardFailed=False,
- content=response
- )
-```
-
-### 4.3 LLM-Based Context Analysis
-
-Instead of using regex patterns, we use the LLM to intelligently determine if the query references conversation history and can be answered from it.
-
-**Conversation Window:**
-```python
-# Consider last 10 conversation turns (5 user + 5 bot pairs)
-CONTEXT_WINDOW_SIZE = 10
-
-def get_recent_history(history: List[ConversationItem]) -> List[ConversationItem]:
- """Get recent conversation history for context analysis."""
- return history[-CONTEXT_WINDOW_SIZE:] if history else []
-```
-
-**LLM Context Check Prompt:**
-```python
-CONTEXT_CHECK_PROMPT = """
-You are a conversation context analyzer. Analyze if the user's current query can be answered using ONLY the conversation history provided.
-
-Conversation History:
-{conversation_history}
-
-Current User Query: "{user_query}"
-
-Task:
-1. First check if this is a greeting/conversational message (hi, hello, thanks, goodbye, etc.)
-2. If it's a greeting: Provide an appropriate friendly response
-3. If NOT a greeting: Determine if the query references or can be answered from the conversation history above
-4. If YES: Extract and provide the answer from the conversation history
-5. If NO: Indicate that it cannot be answered from conversation history
-
-Response Format (JSON only, no explanation):
-{{
- "is_greeting": true/false,
- "can_answer_from_context": true/false,
- "answer": "extracted answer from history OR greeting response" OR null,
- "reasoning": "brief explanation of why it can/cannot be answered"
-}}
-
-Examples of GREETINGS (handle with friendly response):
-- "Tere!" → {"is_greeting": true, "answer": "Tere! Kuidas saan teid aidata?"}
-- "Hello" → {"is_greeting": true, "answer": "Hello! How can I help you?"}
-- "Thanks!" → {"is_greeting": true, "answer": "You're welcome!"}
-- "Good morning" → {"is_greeting": true, "answer": "Good morning! What can I do for you?"}
-
-Examples of queries that CAN be answered from context:
-- "What did you say earlier about that?"
-- "Can you repeat that?"
-- "What was the rate you mentioned?"
-- "Tell me more about what you just said"
-
-Examples of queries that CANNOT be answered from context:
-- Completely new topics
-- Requests for real-time data
-- Questions requiring external knowledge
-"""

-
-### 4.4 Advantages of LLM-Based Approach
-
- **No Regex Pattern Maintenance**: LLM understands semantic context references naturally
- **Handles Edge Cases**: Can detect implicit references that regex would miss
- **Multilingual Support**: Works across Estonian, English, and other languages
- **Structured Output**: Consistent JSON format for easy parsing
- **Reasoning Transparency**: Includes explanation of decision
- **Streaming Compatible**: Fast context check + token-by-token answer delivery
- **Greeting Detection**: Automatically handles greetings, farewells, and conversational pleasantries
- **Natural Responses**: LLM generates contextually appropriate greeting responses
-
-### 4.7 Fallback Strategy
-
-**Fallback to Layer 3 (RAG):**
-- If `is_greeting = false` AND `can_answer_from_context = false`
-- If LLM response parsing fails
-- If conversation history is empty (and not a greeting)
-- If output guardrails block the response (fallback to RAG for alternative answer)
-
-**Error Handling:**
-```python
-try:
- result = await execute_context_workflow(
- request, llm_manager, guardrails_adapter, costs_metric
- )
- if result:
- return result # Context-based answer (validated)
- else:
- # Move to Layer 3 (RAG)
- return await execute_rag_workflow(request, components, costs_metric)
-except Exception as e:
- logger.error(f"Context workflow failed: {e}")
- # Fallback to RAG workflow
- return await execute_rag_workflow(request, components, costs_metric)
-```
-
-**Guardrail Violation Fallback:**
-```python
-# Option 1: Return error message (current approach)
-if not output_check.allowed:
- return create_guardrail_violation_response(request)
-
-# Option 2: Fallback to RAG (alternative approach)
-if not output_check.allowed:
- logger.warning("Context response blocked, trying RAG workflow")
- return await execute_rag_workflow(request, components, costs_metric)
-```

-## 5. Layer 3: RAG Workflow
-
-### 5.1 Integration with Existing System
-
-**Trigger**: When both Layer 1 (Service) and Layer 2 (Context) fail to match
-
-**Implementation:**
-```python
-# Reuse existing RAG pipeline
-return self._execute_orchestration_pipeline(
- request, components, costs_metric, time_metric
-)
-```
-
-**Existing Flow (No Changes Required):**
-1. Prompt Refinement
-2. Contextual Retrieval (Qdrant + BM25)
-3. Rank Fusion (RRF)
-4. Response Generation
-5. Output Guardrails (validation-first streaming already implemented)
-
-**Streaming with Output Guardrails (Current Implementation):**
-```python
-# RAG workflow uses validation-first approach
-async for validated_chunk in guardrails_adapter.stream_with_guardrails(
- user_message=refined_query,
- bot_message_generator=llm_streaming_generator
-):
- # NeMo buffers tokens (chunk_size=200)
- # Validates each buffer before yielding
- yield format_sse(chatId, validated_chunk)
-
-yield format_sse(chatId, "END")
-```
-
-**Fallback:**
-- If no chunks found (`len(relevant_chunks) == 0`) → Layer 4 (OOD)
-- If response confidence low → Layer 4 (OOD)

-## 5.2 Streaming + Output Guardrails Comparison
-
-### Summary: How Each Workflow Handles Streaming + Validation
-
-| Workflow | Response Source | Validation Approach | Streaming Method |
-|----------|----------------|---------------------|------------------|
-| **RAG** | LLM streaming generation | NeMo buffers + validates chunks (chunk_size=200) | `stream_with_guardrails()` wraps bot generator |
-| **Service** | External service (complete) | Validate complete response | Stream validated response token-by-token |
-| **Context** | LLM structured output (complete) | Validate complete response | Stream validated response token-by-token |
-| **OOD** | Fixed message | No validation needed | Stream fixed message token-by-token |
-
-### Technical Flow for Each Workflow
-
-#### RAG Workflow (Existing - Validation-First)
-
-**Non-Streaming:**
-```python
-response = await response_generator.generate(...)
-output_check = await guardrails_adapter.check_output_async(response)
-if output_check.allowed:
- return OrchestrationResponse(content=response)
-```
-
-**Streaming:**
-```python
-# LLM generates via streaming
-async def bot_generator():
- async for token in llm.stream():
- yield token
-
-# NeMo validates in real-time (buffers chunks)
-async for validated_chunk in guardrails_adapter.stream_with_guardrails(
- user_message=query,
- bot_message_generator=bot_generator
-):
- yield format_sse(chatId, validated_chunk) # Already validated
-```
-
-#### Service Workflow (New - Validate Then Stream)
-
-**Non-Streaming:**
-```python
-service_response = await call_external_service(...) # Complete response
-output_check = await guardrails_adapter.check_output_async(service_response)
-if output_check.allowed:
- return OrchestrationResponse(content=service_response)
-else:
- return GuardrailViolationResponse()
-```
-
-**Streaming:**
-```python
-service_response = await call_external_service(...) # Complete response
-
-# Validate complete response FIRST
-output_check = await guardrails_adapter.check_output_async(service_response)
-if not output_check.allowed:
- yield format_sse(chatId, OUTPUT_GUARDRAIL_VIOLATION_MESSAGE)
- yield format_sse(chatId, "END")
- return
-
-# Validated - now stream to client token-by-token
-for token in split_into_tokens(service_response, chunk_size=5):
- yield format_sse(chatId, token)
- await asyncio.sleep(0.01)
-yield format_sse(chatId, "END")
-```
-
-#### Context Workflow (New - Validate Then Stream)
-
-**Non-Streaming:**
-```python
-context_result = await llm.check_context(query, history) # Complete answer
-if context_result.can_answer_from_context:
- output_check = await guardrails_adapter.check_output_async(context_result.answer)
- if output_check.allowed:
- return OrchestrationResponse(content=context_result.answer)
- else:
- return GuardrailViolationResponse()
-```
-
-**Streaming:**
-```python
-context_result = await llm.check_context(query, history) # Complete answer
-
-if context_result.can_answer_from_context:
- # Validate complete answer FIRST
- output_check = await guardrails_adapter.check_output_async(context_result.answer)
- if not output_check.allowed:
- yield format_sse(chatId, OUTPUT_GUARDRAIL_VIOLATION_MESSAGE)
- yield format_sse(chatId, "END")
- return
-
- # Validated - stream to client token-by-token
- for token in split_into_tokens(context_result.answer, chunk_size=5):
- yield format_sse(chatId, token)
- await asyncio.sleep(0.01)
- yield format_sse(chatId, "END")
-```
-
-### Key Differences
-
-**RAG Workflow:**
-- **Real-time validation**: LLM generates → NeMo validates chunks → Stream to client
-- **Buffered approach**: Tokens buffered in chunks of 200 characters
-- **Bi-directional**: Generator feeding into NeMo, NeMo yielding validated chunks
-- **Cost**: Inline (no separate validation call)
-
-**Service/Context Workflows:**
-- **Pre-validation**: Get complete response → Validate → Stream to client
-- **Complete response**: Already have full text before streaming starts
-- **Uni-directional**: Simply chunk and send validated response
-- **Cost**: Separate validation call tracked in `costs_metric["output_guardrails"]`
-- **UX Consistency**: Simulates streaming to match RAG workflow behavior
-
-### Why Different Approaches?
-
-1. **RAG**: LLM streaming is inherently token-by-token, so NeMo can validate in real-time
-2. **Service**: External API returns complete response, no streaming generation occurs
-3. **Context**: LLM returns structured JSON with complete answer, not streaming
-
-### Common Pattern: Validation-First
-
-All three workflows share the **validation-first principle**:
-- Content is validated BEFORE reaching the user
-- Blocked content never sent to client
-- Consistent safety guarantees across all workflows
-- Streaming provides smooth UX even with complete responses (Service/Context)
-
----
-
-## 6. Layer 4: OOD (Out of Domain) Response
-
-### 6.1 Trigger Conditions
-
-- No service detected (Layer 1 failed)
-- No context match (Layer 2 failed)
-- No relevant knowledge chunks (Layer 3 failed)
-
-### 6.2 Response Generation
-
-**Return localized OOD message:**
-```python
-return OrchestrationResponse(
- chatId=request.chatId,
- llmServiceActive=True,
- questionOutOfLLMScope=True, # Flag as out of scope
- inputGuardFailed=False,
- content=get_localized_message(OUT_OF_SCOPE_MESSAGES, detected_language)
-)
-```
-
-**Existing Constants (Reuse):**
-```python
-# From: src/llm_orchestrator_config/llm_ochestrator_constants.py
-OUT_OF_SCOPE_MESSAGES = {
- "et": "Vabandust, ma ei suuda sellele küsimusele vastata...",

- "connectionId": 1
-}
-```
-
-### 9.2 Response Format (No Changes)
-
-**Success Response:**
-```json
-{
- "chatId": "session-123",
- "llmServiceActive": true,
- "questionOutOfLLMScope": false,
- "inputGuardFailed": false,
- "content": "The current EUR to USD exchange rate is 1.08."
-}
-```
-
-**Service Workflow Response:**
-```json
-{
- "chatId": "session-123",
- "llmServiceActive": true,
- "questionOutOfLLMScope": false,
- "inputGuardFailed": false,
- "content": "Based on the ExchangeRateService: EUR/USD = 1.0850"
-}
-```
-
-The response format remains unchanged. The workflow selection is internal and transparent to the API consumer.
-
----
-
-## 10. Implementation Considerations
-
-### 10.1 Performance Optimization
-
-**Service Discovery Caching:**
-```python
-# Cache active service count for 5 minutes
-@cached(ttl=300)
-async def get_active_service_count() -> int:
- return await db.count_active_services()
-```
-
-**Intent Collection Warm-up:**
-```python
-# Pre-load intent collection on startup
-async def warmup_intent_collection():
- """Ensure intent_collection is ready before processing requests."""
- collection_info = await qdrant_client.get_collection("intent_collection")
- logger.info(f"Intent collection ready: {collection_info.points_count} services")
-```
-
-### 10.2 Monitoring & Analytics
-
-**Tool Classifier Decisions Table:**
-```sql
--- Track classifier decisions for analytics
-CREATE TABLE tool_classifier_decisions (
- id SERIAL PRIMARY KEY,
- chat_id TEXT NOT NULL,
- author_id TEXT,
- user_query TEXT NOT NULL,
- detected_workflow VARCHAR(20) NOT NULL, -- 'service', 'context', 'rag', 'ood'
- classifier_confidence NUMERIC(5,4),
- service_id VARCHAR(100), -- If service workflow
- execution_time_ms INTEGER,
- created_at TIMESTAMP DEFAULT NOW()
-);
-
-CREATE INDEX idx_classifier_decisions_workflow
- ON tool_classifier_decisions(detected_workflow);
-```
-
-### 10.3 Cost Tracking
-
-**Add tracking for new LLM calls:**
-# Service workflow - intent detection
-costs_metric["intent_detection"] = {
- "total_prompt_tokens": usage.prompt_tokens,
- "total_completion_tokens": usage.completion_tokens,
- "total_cost": calculate_cost(usage)
-}
-
-# Context workflow - context availability check
-costs_metric["context_check
-costs_metric["intent_detection"] = {
- "total_prompt_tokens": usage.prompt_tokens,
- "total_completion_tokens": usage.completion_tokens,
- "total_cost": calculate_cost(usage)
-}
-```
-
-### 10.4 Guardrails Strategy
-
-**Output Guardrails Application:**
-```python
-# Apply output guardrails to ALL workflows for consistency
-WORKFLOWS_WITH_OUTPUT_GUARDRAILS = [
- WorkflowType.SERVICE, # Check service responses (may contain PII/sensitive data)
- WorkflowType.CONTEXT, # Check context-based responses (conversation history may have PII)
- WorkflowType.RAG # Existing behavior (knowledge base responses)
-]
-
-# OOD responses skip guardrails (fixed message)
-WORKFLOWS_WITHOUT_OUTPUT_GUARDRAILS = [
- WorkflowType.OOD
-]
-```
-
-**Validation-First Approach:**
-
-All workflows use the **validation-first** approach where content is validated BEFORE streaming to the client:
-
-1. **RAG Workflow** (existing):
- - LLM generates response via streaming
- - NeMo buffers tokens (chunk_size=200)
- - Each buffer validated before yielding
- - Uses `stream_with_guardrails()` method
-
-2. **Service Workflow** (new):
- - External service returns complete response
- - Apply output guardrails validation
- - Stream validated response token-by-token to client
- - Consistent UX with RAG workflow
-
-3. **Context Workflow** (new):
- - LLM returns complete answer from history
- - Apply output guardrails validation
- - Stream validated response token-by-token to client
- - Consistent UX with RAG workflow
-
-**Streaming + Output Guardrails Integration:**
-
-```python
-# For Service and Context workflows
-async def stream_validated_response(
- response_text: str,
- guardrails_adapter: NeMoRailsAdapter,
- request: OrchestrationRequest,
- costs_metric: Dict
-) -> AsyncIterator[str]:
- """
- Apply output guardrails and stream validated response.
-
- Flow:
- 1. Validate complete response with guardrails
- 2. If allowed: Stream token-by-token to client
- 3. If blocked: Send guardrail violation message
- """
- # Check output guardrails (non-streaming validation)
- output_check = await guardrails_adapter.check_output_async(response_text)
-
- # Track costs
- costs_metric["output_guardrails"] = output_check.usage
-
- if not output_check.allowed:
- logger.warning(f"[{request.chatId}] Output blocked by guardrails")
- # Send violation message
- yield format_sse(request.chatId, OUTPUT_GUARDRAIL_VIOLATION_MESSAGE)
- yield format_sse(request.chatId, "END")
- return
-
- # Response validated - stream to client
- logger.info(f"[{request.chatId}] Streaming validated response")
- for token in split_into_tokens(response_text):
- yield format_sse(request.chatId, token)
- await asyncio.sleep(0.01) # Maintain streaming pace
-
- yield format_sse(request.chatId, "END")
-```
-
-**Utility Function for Token Streaming:**
-```python
-def split_into_tokens(text: str, chunk_size: int = 5) -> List[str]:
- """
- Split text into token-like chunks for streaming simulation.
-
- Used by Service and Context workflows to provide streaming UX
- even though the complete response is already available.
-
- Args:
- text: Complete response text
- chunk_size: Number of words per chunk
-
- Returns:
- List of text chunks
- """
- words = text.split()
- tokens = []
- for i in range(0, len(words), chunk_size):
- chunk = " ".join(words[i:i + chunk_size])
- tokens.append(chunk + " " if i + chunk_size < len(words) else chunk)
- return tokens
-```
-
-### 10.5 Streaming Implementation Summary
-
-| Aspect | RAG Workflow | Service Workflow | Context Workflow |
-|--------|--------------|------------------|------------------|
-| **Response Type** | Streaming (token-by-token) | Complete (all at once) | Complete (all at once) |
-| **Validation Timing** | Real-time (buffered chunks) | Pre-validation | Pre-validation |
-| **Guardrail Method** | `stream_with_guardrails()` | `check_output_async()` | `check_output_async()` |
-| **Streaming Reason** | Natural (LLM streams) | UX consistency | UX consistency |

-# Tool Classifier Skeleton - Usage Guide
-
-**Version**: 1.0
-**Date**: February 17, 2026
-**Status**: Skeleton Implementation
-
----
-
-## Overview
-
-This skeleton implements the **framework** for a multi-workflow routing system based on the [TOOL_CLASSIFIER_EXTENSION_SPEC.md](./TOOL_CLASSIFIER_EXTENSION_SPEC.md) specification.
-
-### Current Status
-
- **Implemented (Skeleton)**:
-- Abstract base classes and interfaces
-- Workflow executor skeletons (Service, Context, RAG, OOD)
-- Tool classifier with classification and routing logic
-- Feature flags for safe deployment
-- Integration into LLMOrchestrationService
-
- **Not Implemented (Separate Tasks)**:
-- Service discovery logic (Layer 1)
-- Context analysis logic (Layer 2)
-- Actual LLM calls in workflows
-- Output guardrails integration for new workflows
-- Database schema changes
-
-### Current Behavior
-
-When `TOOL_CLASSIFIER_ENABLED=false` (default):
-- System works exactly as before (RAG-only pipeline)
-- No changes to existing functionality
-
-When `TOOL_CLASSIFIER_ENABLED=true`:
-- Classifier routes queries (currently always to RAG)
-- Service and Context workflows return `None` (fallback to RAG)
-- RAG workflow wraps existing pipeline
-- All queries ultimately handled by RAG
-
----

-```
-
-### Abstract Base Class Pattern
-
-The system uses **BaseWorkflow** as an abstract base class to ensure all workflows follow the same contract.
-
-#### How It Works
-
-1. **BaseWorkflow defines the contract**:
- - Every workflow MUST implement two methods: `execute_async()` and `execute_streaming()`
- - Both methods return `Optional[...]` to support the fallback pattern (return `None` → next layer)
- - Python's `@abstractmethod` decorator enforces this at instantiation time
-
-2. **All workflows inherit from BaseWorkflow**:
- - ServiceWorkflowExecutor extends BaseWorkflow → implements both methods
- - ContextWorkflowExecutor extends BaseWorkflow → implements both methods
- - RAGWorkflowExecutor extends BaseWorkflow → implements both methods
- - OODWorkflowExecutor extends BaseWorkflow → implements both methods
-
-3. **Classifier treats all workflows uniformly**:
- - The `ToolClassifier.route_to_workflow()` method doesn't need to know which specific workflow it's calling
- - It just calls `workflow.execute_async()` or `workflow.execute_streaming()`
- - This is **polymorphism** - same interface, different behavior
-
-4. **Benefits**:
- - **Consistency**: All workflows have the same interface
- - **Enforcement**: Can't create a workflow without implementing required methods
- - **Flexibility**: Easy to add new workflows - just extend BaseWorkflow
- - **Testability**: Each workflow can be tested independently
- - **Fallback Pattern**: `Optional` return type enables layer chaining
-
-#### Example Flow
-
-```
-ToolClassifier needs to execute a workflow
- ↓
-Gets workflow object (could be Service, Context, RAG, or OOD)
- ↓
-Calls workflow.execute_async(request, context)
- ↓
-BaseWorkflow contract guarantees this method exists
- ↓
-Each workflow implements its own logic
- ↓
-Returns OrchestrationResponse or None (fallback to next layer)
-```
-
-The abstract class is like a **blueprint** that says: "Any workflow in this system MUST be able to do these two things: execute normally and execute with streaming. I don't care *how* you do it, but you must provide these capabilities."
-
----
-
-## Feature Flags
-
-### Environment Variables
-
-```bash
-# Master switch (default: false for safe deployment)
-TOOL_CLASSIFIER_ENABLED=false
-
-# Individual workflow toggles (only apply when classifier enabled)
-SERVICE_WORKFLOW_ENABLED=true
-CONTEXT_WORKFLOW_ENABLED=true
-```
-
-### Configuration Class
-
-```python
-from src.llm_orchestrator_config.feature_flags import FeatureFlags
-
-# Check if classifier is enabled
-if FeatureFlags.TOOL_CLASSIFIER_ENABLED:
- # Use tool classifier
- pass
-
-# Check specific workflow
-if FeatureFlags.is_workflow_enabled("service"):
- # Service workflow logic
- pass
-
-# Log current configuration
-FeatureFlags.log_configuration()
-```
-
----
-
-## How It Works
-
-### 1. Non-Streaming Endpoint (`/orchestrate`)
-
-#### Current Flow (TOOL_CLASSIFIER_ENABLED=false)
-
-```python
-POST /orchestrate
- ↓
-LLMOrchestrationService.process_orchestration_request()
- ↓
-Initialize components (LLM, guardrails, retriever, generator)
- ↓
-Execute RAG pipeline
- ↓
-Return OrchestrationResponse
-```
-
-#### With Classifier (TOOL_CLASSIFIER_ENABLED=true)
-
-```python
-POST /orchestrate
- ↓
-LLMOrchestrationService.process_orchestration_request()
- ↓
-Initialize components
- ↓
-Tool Classifier Integration:
- 1. Initialize ToolClassifier (if first time)
- 2. Classify query → ClassificationResult
- - Currently always returns: WorkflowType.RAG
- 3. Route to workflow:
- - ServiceWorkflow.execute_async() → returns None
- - ContextWorkflow.execute_async() → returns None
- - RAGWorkflow.execute_async() → returns response
- ↓
-Return OrchestrationResponse
-```
-
-### 2. Streaming Endpoint (`/orchestrate/stream`)
-
-#### Current Flow (TOOL_CLASSIFIER_ENABLED=false)
-
-```python
-POST /orchestrate/stream
- ↓
-LLMOrchestrationService.stream_orchestration_response()
- ↓
-Initialize components
- ↓
-Check input guardrails
- ↓
-Refine prompt → Retrieve chunks → Stream through NeMo
- ↓
-Yield SSE strings
-```
-
-#### With Classifier (TOOL_CLASSIFIER_ENABLED=true)
-
-```python
-POST /orchestrate/stream
- ↓
-LLMOrchestrationService.stream_orchestration_response()
- ↓
-Initialize components
- ↓
-Check input guardrails
- ↓
-Tool Classifier Integration:
- 1. Initialize ToolClassifier (if first time)
- 2. Classify query → ClassificationResult
- 3. Route to streaming workflow:
- - ServiceWorkflow.execute_streaming() → returns None
- - ContextWorkflow.execute_streaming() → returns None
- - RAGWorkflow.execute_streaming() → yields SSE
- ↓
-Yield SSE strings
-```
-
-### 3. Test Endpoint (`/orchestrate/test`)
-
-Works identically to `/orchestrate`:
-- Converts `TestOrchestrationRequest` → `OrchestrationRequest`
-- Routes through classifier (if enabled)
-- Converts response back to `TestOrchestrationResponse`
-
----
-
-## Code Examples
-
-### Using the Classification System
-
-```python
-from src.tool_classifier import ToolClassifier, WorkflowType, ClassificationResult
-
-# Initialize classifier
-classifier = ToolClassifier(
- llm_manager=llm_manager,
- orchestration_service=service,
-)
-
-# Classify a query
-classification = await classifier.classify(
- query="Hello, how are you?",
- conversation_history=[],
- language="en",
-)
-
-# Check result
-print(classification.workflow) # WorkflowType.RAG (in skeleton)
-print(classification.confidence) # 1.0
-print(classification.reasoning) # "Default to RAG workflow..."
-
-# Route to workflow
-response = await classifier.route_to_workflow(
- classification=classification,
- request=request,
- is_streaming=False,
-)
-```
-
-### Implementing a Workflow (Example)
-
-```python
-from src.tool_classifier.base_workflow import BaseWorkflow
-from models.request_models import OrchestrationRequest, OrchestrationResponse
-
-class MyCustomWorkflow(BaseWorkflow):
- """Custom workflow implementation."""
-
- async def execute_async(
- self,
- request: OrchestrationRequest,
- context: Dict[str, Any],
- ) -> Optional[OrchestrationResponse]:
- """Handle query in non-streaming mode."""
-
- # Check if this workflow can handle the query
- can_handle = await self._check_if_applicable(request.message)
-
- if not can_handle:
- # Return None to trigger fallback to next layer
- return None
-
- # Execute workflow logic
- result = await self._process_query(request.message)
-
- # Validate with output guardrails (TODO)
- # is_safe = await guardrails.check_output_async(result)
- # if not is_safe:
- # return None or violation_response
-
- # Return response
- return OrchestrationResponse(
- chatId=request.chatId,
- llmServiceActive=True,
- questionOutOfLLMScope=False,
- inputGuardFailed=False,
- content=result,
- )
-
- async def execute_streaming(
- self,
- request: OrchestrationRequest,
- context: Dict[str, Any],
- ) -> Optional[AsyncIterator[str]]:
- """Handle query in streaming mode."""
-
- # Check if applicable
- can_handle = await self._check_if_applicable(request.message)
-
- if not can_handle:
- return None # Fallback
-
- # Get complete result
- result = await self._process_query(request.message)
-
- # Validate with guardrails (TODO)
- # is_safe = await guardrails.check_output_async(result)
- # if not is_safe:
- # yield format_sse(chatId, VIOLATION_MESSAGE)
- # yield format_sse(chatId, "END")
- # return
-
- # Stream result token-by-token
- async def stream_result():
- for chunk in self._split_into_tokens(result):
- yield self.format_sse(request.chatId, chunk)
- await asyncio.sleep(0.01)
- yield self.format_sse(request.chatId, "END")
-
- return stream_result()
-```
-
----
-
-## Deployment Strategy
-
-### Phase 1: Testing (Current State)
-
-```bash
-# Keep classifier disabled
-TOOL_CLASSIFIER_ENABLED=false
-```
-
-**Result**: System works exactly as before (RAG-only)
-
-### Phase 2: Enable Classifier (No Impact)
-
-```bash
-# Enable classifier (but workflows not implemented)
-TOOL_CLASSIFIER_ENABLED=true
-SERVICE_WORKFLOW_ENABLED=true
-CONTEXT_WORKFLOW_ENABLED=true
-```
-
-**Result**:
-- Classifier runs but always routes to RAG
-- Service/Context return `None` → fallback to RAG
-- Functionally identical to Phase 1
-- Validates integration works
-
-### Phase 3: Implement Service Workflow
-
-1. Implement service discovery logic (separate task)
-2. Deploy with `SERVICE_WORKFLOW_ENABLED=true`
-3. Monitor service routing behavior
-4. Rollback flag if issues occur
-
-### Phase 4: Implement Context Workflow
-
-1. Implement context analysis logic (separate task)
-2. Deploy with `CONTEXT_WORKFLOW_ENABLED=true`
-3. Monitor greeting/context detection
-4. Rollback flag if issues occur
-
-### Phase 5: Production
-
-All workflows operational, full layer-wise routing active.

-
-## Extending the System
-
-### Adding a New Workflow
-
-1. **Create Workflow Executor**:
-
-```python
-# src/tool_classifier/workflows/custom_workflow.py
-
-from src.tool_classifier.base_workflow import BaseWorkflow
-
-class CustomWorkflowExecutor(BaseWorkflow):
- """Your custom workflow."""
-
- async def execute_async(self, request, context):
- # Implement logic
- pass

-def __init__(self, ...):
- # ... existing workflows ...
- self.custom_workflow = CustomWorkflowExecutor(...)
-```
-

-
-```python
-# src/llm_orchestrator_config/feature_flags.py
-
-CUSTOM_WORKFLOW_ENABLED = (
- os.getenv("CUSTOM_WORKFLOW_ENABLED", "true").lower() == "true"
-)
-```

-
-## Key Concepts
-
-### 1. None Return Pattern
-
-Workflows return `None` when they cannot handle a query:
-
-```python
-if not can_handle:
- return None # Triggers fallback to next layer
-```
-
-This enables the fallback chain: Service → Context → RAG → OOD
-
-### 2. Validation-First Streaming
-
-For Service and Context workflows (complete responses):
-
-```python
-# 1. Get complete response
-response = await call_service(...)
-
-# 2. Validate BEFORE streaming
-is_safe = await guardrails.check_output_async(response)
-
-if not is_safe:
- yield format_sse(chatId, VIOLATION_MESSAGE)
- yield format_sse(chatId, "END")
- return
-
-# 3. Stream validated response
-for chunk in split_into_tokens(response):
- yield format_sse(chatId, chunk)
-yield format_sse(chatId, "END")
-```
-
-### 3. Two Execution Methods
-
-Every workflow implements both:
-- `execute_async()` → For `/orchestrate` (returns complete response)
-- `execute_streaming()` → For `/orchestrate/stream` (yields SSE strings)
-

+# Vault Setup & Usage Guide
+
+A single reference for how HashiCorp Vault is deployed, initialized, and consumed in the
+RAG-Module. It covers the topology, the three Vault Agents, the secret layout, and — in
+depth — **how each agent renews its token and how secrets are rotated**.
+
+Source files this document describes:
+
+- `docker-compose.yml` — service/topology definition
+- `vault/config/vault.hcl` — Vault server config
+- `vault-init.sh` — one-time bootstrap + per-restart reconcile
+- `vault/agents/{gui,cron,llm}/*.hcl` — the three Vault Agent configs
+- `DSL/CronManager/script/store_secrets_in_vault.sh` — writes/rotates secrets
+- `DSL/CronManager/script/delete_secrets_from_vault.sh` — deletes secrets
+
+For the security rationale (threat model, defense-in-depth, access matrix) see the
+companion `docs/VAULT_SECURITY_ARCHITECTURE.md`. This guide focuses on the *operational*
+mechanics.
+
+---
+
+## 1. Topology at a glance
+
+```
+ bykstack (application network) vault-network (internal: true)
+ ┌───────────────────────────────────────────────┐ ┌──────────────────────────────┐
+ │ gui ──────────────► vault-agent-gui :8202 ───┼────────┤ │
+ │ cron-manager ─────► vault-agent-cron :8203 ───┼────────┤ vault :8200 │
+ │ llm-orchestration ► vault-agent-llm :8201 ───┼────────┤ (Raft storage, KV v2, │
+ │ │ │ AppRole auth) │
+ │ vault-init (also on vault-network) ───────────┼────────┤ │
+ └───────────────────────────────────────────────┘ └──────────────────────────────┘
+```
+
+- **`vault`** runs only on `vault-network`, which is `internal: true` — it has **no route to
+ or from the host or the internet**. Port 8200 is never published.
+- **Vault Agents** straddle both networks: they reach `vault` on `vault-network` and are
+ reachable by their owning application on `bykstack`.
+- **Applications** talk *only* to their agent (`VAULT_ADDR=http://vault-agent-*:820x`) and
+ never hold a Vault token themselves. The agent injects the token transparently.
+
+| Service | Agent it uses | Agent address | AppRole | Policy |
+|---|---|---|---|---|
+| `gui` | `vault-agent-gui` | `:8202` | `gui-service` | `gui-policy` |
+| `cron-manager` | `vault-agent-cron` | `:8203` | `cron-manager-service` | `cron-manager-policy` |
+| `llm-orchestration-service` | `vault-agent-llm` | `:8201` | `llm-orchestration-service` | `llm-orchestration-policy` |
+
+---
+
+## 2. Vault server (`vault/config/vault.hcl`)
+
+- **Storage:** Raft, single node (`node_id = vault-node-1`, path `/vault/file`, persisted in
+ the `vault-data` volume). No `retry_join` — a lone node self-bootstraps; adding a self-
+ pointing join was found to cause "Vault is sealed" boot loops.
+- **Listener:** `0.0.0.0:8200`, `tls_disable = true` (TLS is terminated at the network
+ boundary; the network itself is the isolation layer here). Port `8201` is *not* given its
+ own listener because Vault uses it as the internal cluster port automatically.
+- **Lease defaults:** `default_lease_ttl = 168h` (7 days), `max_lease_ttl = 720h` (30 days).
+ These are *system ceilings*; the per-AppRole token TTLs (below) are much shorter and are
+ what actually governs agent renewal cadence.
+- `disable_mlock = false`, `ui = false`, JSON logs at INFO.
+
+Vault boots **sealed**. It must be unsealed before any operation — that is `vault-init`'s
+first job.
+
+---
+
+## 3. Bootstrap & reconcile (`vault-init.sh`)
+
+`vault-init` is a **run-once-then-exit** container (`restart: "no"`). The agents declare
+`depends_on: vault-init: condition: service_completed_successfully`, so they only start
+after init has finished cleanly. It runs `su vault -s /bin/sh /vault-init.sh` after creating
+and `chown`ing the shared agent directories.
+
+The script has two branches, selected by the presence of `/vault/data/.initialized`.
+
+### 3.1 First-time deployment
+
+1. Wait for `/v1/sys/health` to respond.
+2. **Initialize** with Shamir's Secret Sharing: `secret_shares=5`, `secret_threshold=3`.
+ The full response (5 unseal keys + root token) is written to
+ `/vault/data/unseal-keys.json`.
+3. **Unseal** by submitting 3 of the 5 keys.
+4. **Enable engines:** KV v2 at `secret/`, and the AppRole auth method.
+5. **Create three ACL policies** (see §5).
+6. **Create three AppRoles** issuing periodic tokens (see §4 — this is the heart of renewal),
+ via the `ensure_approles` helper. The same helper re-runs on subsequent deploys, so AppRole
+ config changes land without re-initializing Vault.
+7. **Issue credentials:** for each role, fetch the static `role_id` and mint a `secret_id`,
+ writing both to `/agent/credentials/_role_id` and `_secret_id` (`chmod 640`).
+8. **Generate an RSA-2048 keypair** with `openssl` and store it in Vault at
+ `secret/encryption/public_key` and `secret/encryption/private_key`
+ (algorithm `RSA-OAEP`, with `key_id` and `created_at` metadata).
+9. Seed a test LLM secret, then `touch /vault/data/.initialized`.
+
+### 3.2 Subsequent deployment (restart)
+
+1. Check `/v1/sys/seal-status`; if sealed, reload the 3 unseal keys from
+ `unseal-keys.json` and unseal.
+2. **Reconcile each secret_id** via `reconcile_secret_id`:
+ - `ensure_role_id` — make sure the `role_id` file exists (re-fetch from Vault if missing).
+ - `validate_secret_id` — attempt an AppRole login with the on-disk `role_id` + `secret_id`.
+ If it returns a `client_token`, the credential is still good.
+ - **Valid → reuse** the existing `secret_id` (no churn).
+ - **Invalid/missing → `mint_secret_id`** writes a fresh one.
+
+This is deliberate: because the AppRoles are created with `secret_id_ttl=0` and
+`secret_id_num_uses=0` (non-expiring, unlimited-use), a single long-lived `secret_id`
+survives normal restarts instead of being regenerated every boot. The RSA keypair, policies,
+and stored secrets are all preserved across restarts.
+
+> **Note on file permissions:** `vault-init.sh` writes credential files with `chmod 640`.
+> (The older architecture doc mentions `644`; the script is the source of truth — `640`.)
+
+---
+
+## 4. The three Vault Agents — auth, renewal & rotation
+
+This is the core of the question. All three agents are the same Vault binary
+(`hashicorp/vault:1.20.3`) run as `vault agent -config=...`. They differ only in which
+credentials they read, which token sink they write, and their listener port.
+
+### 4.1 What an agent config actually does
+
+Example (`vault/agents/llm/agent.hcl`; gui/cron are identical in shape):
+
+```hcl
+vault { address = "http://vault:8200"; retry { num_retries = 5 } }
+
+auto_auth {
+ method "approle" {
+ mount_path = "auth/approle"
+ config = {
+ role_id_file_path = "/agent/credentials/llm_role_id"
+ secret_id_file_path = "/agent/credentials/llm_secret_id"
+ remove_secret_id_file_after_reading = false
+ }
+ }
+ sink "file" { config = { path = "/agent/llm-token/token"; mode = 0640 } }
+}
+
+cache { default_lease_duration = "1h" }
+listener "tcp" { address = "0.0.0.0:8201"; tls_disable = true }
+api_proxy { use_auto_auth_token = true }
+```
+
+Three mechanisms are at work:
+
+1. **`auto_auth` (authentication + renewal):** On startup the agent reads `role_id` +
+ `secret_id` and calls `POST /v1/auth/approle/login`. Vault returns a **periodic token**
+ (the AppRoles set `token_period`, defined in `vault-init.sh`, *not* in the HCL). The agent
+ then runs Vault's **auto-auth lifecycle manager**, which **renews the token automatically
+ in the background** before each period elapses. A periodic token has **no max-TTL**, so the
+ agent renews it indefinitely and — during normal operation — **never has to call
+ `approle/login` again**. The agent only re-authenticates (and thus only needs the
+ `secret_id` again) if it is **restarted** or if a renewal is missed long enough for the
+ token to lapse. `remove_secret_id_file_after_reading = false` keeps the `secret_id` on disk
+ so the agent can re-auth after a restart without `vault-init` re-minting.
+
+ > **Why periodic tokens?** An earlier design issued tokens with `token_ttl`/`token_max_ttl`,
+ > which forced a full re-login every time `token_max_ttl` was reached. If the `secret_id`
+ > had become invalid by then (expiry, clock skew, server re-init), the agent got stuck in an
+ > `invalid role or secret ID` 400 backoff loop with no way to self-heal. Periodic tokens
+ > remove that re-login from the steady state, so a stale `secret_id` can no longer strand a
+ > running agent.
+2. **`sink "file"` (token hand-off):** Every time the agent obtains/renews a token it writes
+ it to a file (`/agent/-token/token`, mode `0640`). The compose **health check** for
+ each agent is simply `test -f && test -s ` — a non-empty token file means
+ the agent has authenticated successfully.
+3. **`api_proxy { use_auto_auth_token = true }` (transparent injection):** The agent also
+ listens as an HTTP proxy on its port. When the application sends a token-less request, the
+ agent injects `X-Vault-Token: ` and forwards it to `vault:8200`.
+ This is why application code never sets `VAULT_TOKEN`.
+
+> **`cache.default_lease_duration` is not the token TTL.** It is the agent's cache lease
+> hint. The authoritative token lifetime comes from the AppRole's `token_period` in
+> `vault-init.sh`. The per-agent cache hint is set to match the period.
+
+### 4.2 Per-agent renewal parameters
+
+AppRole token settings are created in `vault-init.sh`; all three use
+`token_period` (periodic token, **no max-TTL**), `secret_id_ttl=0`, `secret_id_num_uses=0`,
+`token_num_uses=0`, `bind_secret_id=true`.
+
+| Agent | AppRole | `token_period` | Proactive renewal (~⅔ of period) | Re-login (`approle/login`) |
+|---|---|---|---|---|
+| `vault-agent-gui` | `gui-service` | **20m** | ~every 13 min | only on agent restart |
+| `vault-agent-cron` | `cron-manager-service` | **30m** | ~every 20 min | only on agent restart |
+| `vault-agent-llm` | `llm-orchestration-service` | **1h** | ~every 40 min | only on agent restart |
+
+Reading the lifecycle for, e.g., the LLM agent:
+
+```
+T=0 login → periodic token (period 1h) → written to /agent/llm-token/token
+T≈40m renew-self → period resets to 1h → token file refreshed
+... renew repeats forever; token never hits a max-TTL
+(restart) agent re-runs approle/login with the on-disk secret_id → fresh token
+```
+
+The periods are tuned per service (shorter for the GUI, which only reads the public key;
+longer for the high-traffic LLM read path), but functionally all three behave the same:
+**renew forever, re-login only on restart.**
+
+### 4.3 Two distinct "rotation" concepts — keep them separate
+
+1. **Token rotation (automatic, continuous):** Handled entirely by the agent's `auto_auth`
+ loop as described above — the periodic token is renewed indefinitely with no human action
+ and no `vault-init` involvement.
+2. **`secret_id` rotation (rare):** The `secret_id` is the long-lived credential the agent
+ uses to *log in* (at startup/restart only, now that tokens are periodic). It is configured
+ non-expiring (`secret_id_ttl=0`, `secret_id_num_uses=0`) and is only replaced by
+ `vault-init` on a restart when the existing one fails validation (§3.2). To force rotation,
+ delete the `secret_id` file (or invalidate it in Vault) and re-run `vault-init`, then
+ restart the agent so it logs in with the freshly minted one.
+
+ > **Operational caveat (learned the hard way):** if a `secret_id` ever does become invalid
+ > while an agent is running, the periodic-token design means a *running* agent keeps working
+ > (it only renews, never re-logs-in). But a **restarted** agent needs a valid `secret_id` to
+ > log in. Recovery is always: re-run `vault-init` (mints a fresh `secret_id` via the §3.2
+ > reconcile) → restart the affected agent. See `docs/` runbook / the troubleshooting note
+ > below.
+
+### 4.4 Restart behavior
+
+- **Restart an agent:** It re-reads `role_id`/`secret_id` from the (read-only) creds volume
+ and re-authenticates. New token, written to the sink. App sees a brief blip.
+- **Restart `vault`:** Data persists; `vault-init` (or the existing agent tokens, if still
+ valid) handle re-unseal/re-auth. Existing tokens remain valid if not expired.
+- **Full `down && up`:** Order is `vault → vault-init → agents → apps`. `vault-init` detects
+ the `.initialized` flag, skips first-time setup, reconciles secret_ids, and the agents
+ start with validated credentials.
+
+---
+
+## 5. Authorization — policies (who can touch what)
+
+Created in `vault-init.sh`. Paths are KV v2, so data lives under `secret/data/...` and
+listing/metadata under `secret/metadata/...`.
+
+| Path | `gui-policy` | `cron-manager-policy` | `llm-orchestration-policy` |
+|---|---|---|---|
+| `secret/data/encryption/public_key` | **read** | read | — |
+| `secret/data/encryption/private_key` | **deny** | **read** | — |
+| `secret/data/encryption/*` | — | — | **deny** |
+| `secret/data/llm/connections/*` | deny | **create/read/update/delete** | **read, list** |
+| `secret/data/embeddings/connections/*` | deny | **create/read/update/delete** | **read, list** |
+| `auth/token/lookup-self` | — | read | read |
+
+The intent, by tier:
+
+- **GUI** — can read *only* the public key, to encrypt user-entered credentials in the
+ browser before they ever leave it. Everything else is explicitly denied.
+- **CronManager** — the only writer. Reads the **private key** to decrypt what the GUI
+ encrypted, then writes plaintext credentials into Vault. Full CRUD on connection secrets.
+- **LLM Orchestration** — read-only consumer of connection secrets. **Explicitly denied** all
+ encryption keys, so a compromise of this hot-path service cannot exfiltrate the private key.
+
+---
+
+## 6. Secret layout (KV v2 under `secret/`)
+
+```
+secret/
+├── llm/connections// ← e.g. aws_bedrock, azure_openai
+├── embeddings/connections//
+└── encryption/
+ ├── public_key { key, algorithm: RSA-OAEP, key_size: 2048, key_id, created_at }
+ └── private_key { key, algorithm: RSA-OAEP, key_size: 2048, key_id, created_at }
+```
+
+The current write/delete scripts key connection secrets by a stable **`vaultUuid`** as the
+final path segment (environment is tracked in the DB, not the path). KV v2 versions every
+write, so updating a credential keeps prior versions for audit/rollback.
+
+LLM secret shape (AWS): `{ connection_id, access_key, secret_key, model, tags }`.
+Azure: `{ connection_id, endpoint, api_key, deployment_name, model, api_version, tags }`.
+
+---
+
+## 7. Usage flows
+
+### 7.1 Storing / rotating a credential (`store_secrets_in_vault.sh`, via cron-manager)
+
+1. GUI encrypts the raw key with the RSA **public** key and submits it.
+2. The cron-manager job runs the script against `vault-agent-cron:8203` (no token — the agent
+ injects it).
+3. The script **fetches the private key** (`GET secret/data/encryption/private_key`), then
+ decrypts each sensitive field in-memory via `decrypt_vault_secrets.py` (RSA-OAEP).
+4. It builds the JSON payload with `jq` and `POST`s plaintext to
+ `secret/data//connections//`. Re-posting the same path
+ = a KV v2 version bump = credential rotation.
+5. Sensitive shell variables are `unset` immediately after use.
+
+### 7.2 Deleting a credential (`delete_secrets_from_vault.sh`)
+
+`DELETE`s both `secret/data/...` and `secret/metadata/...` for the connection (404 treated as
+success), again through `vault-agent-cron` with no explicit token.
+
+### 7.3 Reading a credential (LLM orchestration)
+
+The LLM service issues a token-less `GET http://vault-agent-llm:8201/v1/secret/data/llm/...`.
+`vault-agent-llm` injects its cached token, Vault validates it against
+`llm-orchestration-policy`, and returns the secret. The service then calls AWS/Azure with it.
+

+## 8. Operational notes & known trade-offs
+
+- **Unseal keys + root token sit in the `vault-data` volume** (`unseal-keys.json`). This makes
+ auto-unseal on restart trivial but is a **dev/test convenience**. For production, switch to
+ auto-unseal backed by a cloud KMS/HSM and remove the keys from the volume.
+- **Root token** is used only by `vault-init` and is never injected into app containers. Best
+ practice for production is to revoke it after bootstrap and use scoped admin policies.
+- **TLS is disabled** on the Vault listener and agent listeners; isolation relies on the
+ `internal: true` `vault-network`. Add TLS for any non-local deployment.
+- **Audit logging is available but not enabled.** Turn it on with
+ `vault audit enable file file_path=/vault/logs/audit.log` (the `./vault/logs` mount already
+ exists) for a full request trail.
+- **Credential files are world-readable within the shared volume** (mode 640, single owner,
+ but all agents mount the same `vault-agent-creds` volume read-only) — isolation is at the
+ volume level, not per-file. Fine for this trust boundary; note it if the threat model
+ tightens.
+
+---
+
+## 9. Troubleshooting: agents looping on `invalid role or secret ID`
+
+**Symptom:** an agent logs `lifetime watcher done channel triggered, re-authenticating`
+followed by repeating `PUT .../auth/approle/login → Code: 400 ... invalid role or secret ID`
+with growing backoff. Token *renewals* had been succeeding up to that point.
+
+**Cause:** the agent's `secret_id` became invalid server-side (expiry, clock skew, or a Vault
+re-init), and the agent reached a point where it had to do a full `approle/login`. With the
+old `token_ttl`/`token_max_ttl` design this happened on every `token_max_ttl` cycle; the
+switch to **periodic tokens** (§4) removes re-login from steady state, so a *running* agent no
+longer hits this — but a **restarted** agent still needs a valid `secret_id`.
+
+**Recovery:**
+
+```bash
+# Mint fresh secret_ids (vault-init's reconcile detects the invalid ones and replaces them)
+docker compose up -d --force-recreate vault-init
+docker wait vault-init
+# Restart the affected agents so they log in with the fresh secret_id
+docker compose restart vault-agent-gui vault-agent-cron vault-agent-llm
+```
+
+**Confirm root cause (read-only):**
+
+```bash
+ROOT=$(docker exec vault sh -c "grep -o '\"root_token\":\"[^\"]*\"' /vault/file/unseal-keys.json | cut -d: -f2 | tr -d '\"'")
+docker exec -e VAULT_TOKEN=$ROOT -e VAULT_ADDR=http://127.0.0.1:8200 vault \
+ vault read auth/approle/role/gui-service # expect token_period set, secret_id_ttl=0
+echo "host: $(date -u)"; docker exec vault date -u # check for WSL2/Docker clock drift
+```

+ CLASSIFICATION RULES:
+
+ param_update — The user is modifying or refining the SAME intent with different parameter values.
+ Examples:
+ - Previous: "Show public holidays in 2026" → Current: "What about 2025 instead?" → param_update
+ (same holiday lookup intent, only the year changed)
+ - Previous: "Convert EUR to USD" → Current: "What about GBP to JPY?" → param_update
+ (same currency conversion intent, only currencies changed)
+ - Previous: "Weather in Tallinn" → Current: "And in Tartu?" → param_update
+ (same weather intent, only city changed)
+
+ response_question — The user is asking a question ABOUT the data/results already returned.
+ Examples:
+ - Previous: "List public holidays in 2026" → Response showed 12 holidays → Current: "Which of those falls on a Monday?" → response_question
+ (asking about the already-returned data, no new API call needed)
+ - Previous: "Show electricity prices" → Response showed prices → Current: "Why is the price so high in January?" → response_question
+ (analysing the returned results, not requesting new data)
+ - Previous: "Get train schedule from Tallinn to Tartu" → Response showed times → Current: "How long does the first journey take?" → response_question
+ (asking about details within the returned results)
+
+ new_intent — The user is starting a completely different request, unrelated to the previous API call.
+ Examples:
+ - Previous: "Show public holidays in 2026" → Current: "How do I apply for a driving licence?" → new_intent
+ (completely different topic)
+ - Previous: "Convert EUR to USD" → Current: "What is the weather in Riga?" → new_intent
+ (unrelated request)
+ - Previous: "Get train schedules" → Current: "Tell me about Estonian history" → new_intent
+ (no connection to the previous API call)

+ - Understand Estonian, Russian, and English queries equally
+ - Short follow-ups like "ja 2025?" (Estonian: "and 2025?") or "а в 2025?" (Russian: "and in 2025?") are param_update
+ - Language of the query does NOT affect classification — only intent relationship matters

+ - follow_up_type MUST be exactly one of: "param_update", "response_question", "new_intent"

+ * **Pass 0** — Counts how many *incomplete* endpoints define each param name.
+ This detects conflicts among endpoints that are actively requesting params.
+ Completed endpoints do not participate in conflict detection. Names that
+ appear in more than one incomplete endpoint are "conflicting" and will
+ be namespaced in Pass 1 so each intent can supply an independent value.
+
+ * **Pass 1** — Iterates over *incomplete* endpoints only to build
+ ``merged_schema``. *Non-conflicting* params are deduplicated by name;
+ the first occurrence's definition (type, description) is used. A type
+ conflict is logged as a warning. A param is ``required=True`` in the
+ merged schema if it is required in **any** owning endpoint.
+ *Conflicting* params are emitted as ``{name}__{endpoint_idx}`` so all
+ intents receive their own entry in the schema simultaneously. Duplicate
+ values across endpoints are handled after distribution by
+ ``_enforce_sequential_conflicting_params``.
+
+ * **Pass 2** — Iterates over *completed* endpoints and adds them to
+ ``param_owners`` for any *non-namespaced* param name already present
+ in the merged schema. This ensures that if a shared non-conflicting
+ param is re-extracted or corrected in a later turn the updated value
+ is distributed back to completed endpoint states. Completed endpoints
+ do not affect conflict detection or namespacing.

+ CRITICAL LANGUAGE RULE:
+ - ALWAYS write the unified_answer in the language specified by response_language.
+ - IGNORE the language of any text inside api_results_block — the data may contain
+ names or labels in a different language; the answer must still be in response_language.
+ - IGNORE the language of user_query for output language decisions — short follow-up
+ messages are unreliable indicators. Always use response_language.
+
+ If custom_instructions is non-empty, follow those rules with HIGHEST PRIORITY —
+ they override defaults (e.g. language policy, tone, formatting style).
+
+ Rules:
+ - Present each API result in its OWN separate paragraph, in the same order they
+ appear in api_results_block. Separate paragraphs with a single blank line.
+ Do NOT merge or blend information from different endpoints into one paragraph.
+ - Each paragraph should be self-contained and answer the part of the user's query
+ that corresponds to that endpoint.
+ - Address EVERY result section in api_results_block. Do not silently omit any endpoint.
+ - Within each paragraph, present the information naturally in prose or a short list.
+ Do NOT return raw JSON or wrap content in code blocks.
+ - If a result section includes a 'Parameters used:' line, acknowledge the date range or
+ time period for that result in your discussion
+ (e.g. 'For the period 1 Jan to 30 Jun 2026, XYZ showed...').
+ - If a result is marked [EMPTY RESPONSE], politely mention that no data was available
+ from that source without dwelling on it.
+ - If a result contains an error field or is marked [FAILED], acknowledge the failure
+ briefly and in a friendly, non-technical way, then continue with the remaining results.
+ - If api_results_block contains only empty or failed results, respond with a polite
+ message that no results were available.
+ - If num_results is 1, a single paragraph is fine (no need to split).
+ - Output must be clean text — no markdown headers (##), no code blocks (```), no raw
+ JSON. The answer must be ready for direct display to the user.
+ - Be concise but complete. Prioritise the most relevant information for the user's query.
+
+ STRICT ENDING RULE — HIGHEST PRIORITY:
+ The unified_answer MUST end immediately after the last data point. It is FORBIDDEN to
+ append any sentence that:
+ - offers to provide more details (e.g. "If you need statistics for a specific member...")
+ - invites the user to ask a follow-up question (e.g. "Let me know if...", "Feel free to ask...")
+ - mentions that a dataset is large or partial (e.g. "only a sample is shown here")
+ - suggests the user can specify a name, party, or other filter
+ The very last character of unified_answer must be part of the actual data, not a helper offer.

+"""Langfuse observation utilities with graceful degradation.
+
+Two canonical tracing patterns are used throughout this codebase. Always use
+the helpers defined here rather than calling ``get_client()`` directly.
+
+Pattern A — Non-streaming (single LLM call wrapped with ``@observe``):
+ Use ``@observe(name="...", as_type="generation")`` on the method, then call
+ ``update_observation_safe()`` at the end to attach input/output/cost data.
+
+ NOTE: Use ``as_type="generation"`` (not ``"chain"``) for any method that makes
+ exactly one LLM call. ``"chain"`` extends the async observation context longer
+ than a single LLM call, which can cause DSPy history entries from *this* step
+ to bleed into the baseline capture of the *next* step, inflating cost reports.
+ Reserve ``"chain"`` for orchestration methods that call multiple
+ ``@observe``-decorated children (Langfuse auto-aggregates their costs).
+
+Pattern B — Streaming (``async def`` that ``yield``s tokens):
+ Do NOT put ``@observe`` on async generators — the decorator interferes with
+ async iteration. Use ``safe_observation_context()`` as a context manager
+ instead, then call ``generation.update()`` once after streaming finishes.
+
+Pattern C — Orchestration calling multiple observed children:
+ Use ``@observe(name="...", as_type="chain")``. No manual update needed;
+ Langfuse auto-aggregates child generations.
+
+Pattern D — Pipeline step with no LLM call:
+ Use ``@observe(name="...", as_type="span")``. Optionally call
+ ``get_client().update_current_span(metadata={...})`` for extra context.

+Integration Test — Multi-Intent Parallel API Tool Classification
+================================================================
+
+Tests Phase 1 of the multi-intent ATC feature end-to-end via /orchestrate.
+
+The current Phase 1 implementation uses a temporary single-endpoint fallback:
+IntentDecomposer detects parallel intent → both endpoints stored in context →
+first matched endpoint used for param collection. True parallel execution
+(collecting params for all endpoints simultaneously) arrives in Phase 6.
+
+What these tests verify
+-----------------------
+- Queries with multiple independent intents still route to ATC (not RAG/OOD)
+- The temporary first-endpoint fallback correctly collects params and completes
+- Single-intent queries in the ambiguous cosine band are unaffected (regression)
+- Estonian multi-intent queries decompose and route correctly
+- Sub-queries that both resolve to the same endpoint are deduplicated → single
+ path fallback (no crash, no duplicate calls)
+- When one sub-query finds no matching endpoint (OOD intent mixed in), the
+ system gracefully falls back to the single matched endpoint
+- A query spanning 3 distinct domains hits the MULTI_API_MAX_ENDPOINTS=3 cap
+ and still completes correctly
+
+Scenarios
+---------
+ MI-1 Parallel — vehicle tax + initiative details (2 distinct endpoints)
+ MI-2 Parallel — public holidays + electricity prices (distinct domains)
+ MI-3 Parallel — parliament votings + participation stats (same domain)
+ MI-4 Estonian multi-intent — vehicle tax + initiatives list
+ MI-5 Single-intent regression — address search (should stay single path)
+ MI-6 Deduplication fallback — both sub-queries hit the same endpoint
+ MI-7 Mixed ATC + OOD intent — one sub-query finds no endpoint → graceful fallback
+ MI-8 Three-domain query — address + holidays + electricity (3-way parallel cap)
+

+"""
+DeepEval tests for the API Tool Calling feature (issue #447).
+
+Covers the single-intent (Scenarios 1-4) and multi-intent (MI-1..MI-8) scenarios
+listed in the issue against the running orchestration service. Each scenario
+walks the ``/orchestrate`` endpoint turn-by-turn via the testcontainers-backed
+``orchestration_client`` fixture, extracts the final agentic-loop tool call,
+and scores it with a DeepEval agentic metric:
+
+* **Strict single-intent (S1, S2a, S2b, S3)** — the issue specifies an
+ "Expected endpoint" + URL/params per scenario. Scored with
+ ``ToolCorrectnessMetric`` (deterministic name + input-parameter comparison,
+ ``threshold=1.0``).
+
+* **Loose single-intent (S4)** — the issue documents the 5-turn flow but does
+ not specify an expected resolution. Scored with
+ ``ArgumentCorrectnessMetric`` (LLM-as-judge over the conversation input and
+ the resolved tool call).
+
+* **Multi-intent (MI-1..MI-8)** — issue lists only queries (EN+ET). If the
+ system resolves a tool call, scored with ``ArgumentCorrectnessMetric``; if
+ it asks a clarifying question instead, the test only verifies routing to
+ ATC (i.e. non-empty reply, not silent RAG/OOD).
+
+Endpoints are matched by ``name`` — the UUIDs in the issue do happen to match
+those in ``tests/api_tool_eval/test-endpoints.json``, but name matching is the
+stable contract.
+
+Depends on:
+* ``orchestration_client`` — provides the testcontainers-mapped base URL.
+* ``api_tool_endpoints_indexed`` — seeds the API tool fixture into Qdrant's
+ ``api_tool_collection`` so the agentic loop can find the endpoints.
