+# Kontextual Engine Functional Requirements Specification V0.1
+
+## kontextual-engine
+
+---
+
+## 1. System Overview
+
+kontextual-engine is a **headless knowledge system** that enables persistent storage, transformation, retrieval, and AI-driven operation of structured and semi-structured knowledge across heterogeneous data sources.
+
+This FRS defines the **externally observable functional behavior** of the system.
+
+---
+
+## 2. Actors and Interfaces
+
+### 2.1 Primary Actors
+
+* **User (Human Operator)** via API or service interface
+* **Automation System (`atm`)** executing workflows
+* **LLM Agent (`agt`)** interacting with knowledge and workflows
+* **External Systems** integrating via APIs
+
+---
+
+### 2.2 System Interfaces
+
+* Service API (HTTP, RPC, or equivalent)
+* Programmatic API (SDK/library interface)
+* Storage interface (abstracted from implementation)
+
+---
+
+## 3. Functional Requirements
+
+---
+
+## 3.1 Knowledge Persistence
+
+### FR-001: Store Knowledge Artifacts
+
+**Description:**
+The system must allow storage of knowledge artifacts.
+
+**Input:**
+

+
+**Output:**
+
+* Persisted knowledge artifact with identifier
+
+---
+
+### FR-002: Retrieve Knowledge Artifacts
+
+The system must allow retrieval of stored knowledge artifacts by identifier or query.

+
+The system must allow modification of existing knowledge artifacts.
+
+---
+
+### FR-004: Delete Knowledge Artifacts
+
+The system must allow removal of stored knowledge artifacts.
+
+---
+
+## 3.2 Knowledge Organization
+
+### FR-010: Group Knowledge into Collections
+
+The system must allow grouping knowledge artifacts into collections or domains.
+
+---
+
+### FR-011: Maintain Relationships
+
+The system must allow defining and retrieving relationships between knowledge artifacts.
+
+---
+
+## 3.3 Ingestion and Normalization
+
+### FR-020: Ingest Multi-Format Data
+
+The system must accept input from multiple data formats (e.g. markdown, documents, files).
+
+---
+
+### FR-021: Normalize Data
+
+The system must convert ingested data into a structured representation usable by the system.
+
+---
+
+## 3.4 Query and Retrieval
+
+### FR-030: Query Knowledge
+
+The system must allow querying knowledge artifacts based on:
+
+* Content
+* Metadata
+* Relationships
+
+---
+
+### FR-031: Return Query Results
+
+The system must return matching knowledge artifacts and associated data.
+
+---
+
+## 3.5 Transformation and Composition
+
+### FR-040: Transform Knowledge Artifacts
+
+The system must allow applying transformations to knowledge artifacts.
+
+---
+
+### FR-041: Compose Knowledge
+
+The system must allow combining multiple knowledge artifacts into derived outputs.
+
+---
+
+## 3.6 Workflow Orchestration
+
+### FR-050: Execute Workflows
+
+The system must allow execution of multi-step workflows on knowledge artifacts.
+
+---
+
+### FR-051: Manage Workflow Dependencies
+
+The system must handle dependencies between workflow steps.
+
+---
+
+### FR-052: Provide Workflow Results
+
+The system must return results of workflow execution.
+
+---
+
+## 3.7 AI Interaction
+
+### FR-060: Support AI-Driven Operations
+
+The system must allow AI agents to:
+
+* Access knowledge
+* Trigger transformations
+* Participate in workflows
+
+---
+
+### FR-061: Maintain Context for AI Interaction
+
+The system must provide contextual information to support AI-driven operations.
+
+---
+
+## 3.8 Integration with External Tools
+
+### FR-070: Integrate with Tooling
+
+The system must allow integration with external tooling (e.g. markitect-tool).
+
+---
+
+### FR-071: Accept External Processing Results
+
+The system must accept outputs from external tools and incorporate them into knowledge.
+
+---
+
+## 3.9 API Interaction
+
+### FR-080: Provide API Access
