P257 — AIEP — Evidence-Native Reasoning Development Environment

Applicant: Neil Grassby Classification: Patent Application — Confidential Priority: Claims priority from GB2519711.2 filed 20 November 2025 Architecture Layer: AIEP Phase 2 Developer Tooling Layer

Framework Context

[0001] This specification operates within an AIEP environment as defined in GB2519711.2 and GB2519798.9. The present specification defines a specialised development environment for engineers implementing components that interact with the AIEP evidence ledger, CWSG, and reasoning subsystems.

Field of the Invention

[0002] The present invention relates to evidence-native software development environments for evidence-bound AI systems.

Background

[0003] Developing components that interact with an AIEP evidence architecture requires tools that make the evidence ledger, CWSG state, reasoning traces, and provenance chains visible and manipulable during development. Standard software development environments lack the AIEP-specific tooling needed to develop, debug, and test evidence-bound components effectively.

Summary of the Invention

[0004] The invention provides an Evidence-Native Reasoning Development Environment (ENRDE) that: provides an interactive CWSG browser enabling developers to inspect world state nodes, edges, and evidence chains; provides a reasoning trace viewer showing step-by-step evidence activation and inference chains; includes a synthetic evidence injection tool for test scenario construction; provides a governance policy simulator showing how candidate governance policies would evaluate a configured action scenario; and includes a Reasoning Receipt inspector (P247) for reviewing signed action proofs.

Detailed Description

[0005] CWSG Browser. An interactive graph visualisation tool that renders CWSG nodes and edges with entity attributes, evidence citations, and staleness indicators. Supports query-driven subgraph exploration and evidence chain traversal.

[0006] Reasoning Trace Viewer. Displays reasoning session traces as step-by-step views of evidence activation, CWSG traversal paths, hypothesis simulation steps, and intermediate conclusions. Enables developers to follow the reasoning chain and identify unexpected behaviours.

[0007] Synthetic Evidence Injection Tool. Enables developers to construct test evidence artefacts satisfying the evidence admission schema, inject them into a development instance, and observe downstream world state and reasoning effects.

[0008] Governance Policy Simulator. Accepts a candidate governance policy document, a world state context, and a candidate action, and shows the evaluation outcome of the policy (APPROVE/REJECT/ESCALATE) with the evaluation trace showing which rules fired.

[0009] AIEP API Mock Layer. A local mock implementation of the AIEP component interfaces for offline development and unit testing without a live AIEP instance.

Technical Effect

[0010] The invention provides a purpose-built development environment that makes evidence-grounded reasoning architectures inspectable and testable at the same semantic level that the architecture operates, addressing the fundamental debugging difficulty in evidence-based AI systems: that standard debuggers expose machine state rather than reasoning state. By providing CWSG browser, reasoning trace viewer, synthetic evidence injection, and governance policy simulation in a single co-ordinated environment, the toolset enables developers to construct and verify reasoning behaviour without requiring a live production AIEP cluster.

Claims

1. A method of providing a development, debugging, and testing environment for an evidence-bound artificial intelligence system, comprising the steps of: (a) providing an interactive CWSG browser enabling navigation and inspection of world-state entity nodes, causal edges, edge weights, and the evidence artefacts that admitted each edge; (b) providing a reasoning trace viewer displaying session traces as step-by-step sequences showing evidence activation events, CWSG traversal paths, hypothesis simulation steps, intermediate conclusions, and budget consumption; (c) providing a synthetic evidence injection tool enabling construction of test evidence artefacts satisfying the evidence admission schema and injection of those artefacts into a development instance CWSG, with observable downstream world-state and reasoning effects; (d) providing a governance policy simulator accepting a candidate governance policy document, a world-state context, and a candidate action, and returning the governance evaluation outcome (APPROVE/REJECT/ESCALATE) with the full rule-firing trace; (e) providing an AIEP API mock layer implementing the AIEP component interfaces locally for offline development and unit testing without a live AIEP instance.

2. The method of claim 1, wherein the CWSG browser provides temporal filtering to display the world state as it existed at any past timestamp recorded in the evidence ledger.

3. The method of claim 1, wherein the reasoning trace viewer supports diff view, comparing two session traces to identify the specific divergence point between expected and actual reasoning paths.

4. The method of claim 1, wherein the synthetic evidence injection tool validates candidate artefacts against the admission schema before injection and reports validation errors with field-level detail.

5. The method of claim 1, wherein the governance policy simulator can batch-evaluate a policy across multiple world-state contexts and candidate actions, producing a summary evaluation report.

6. An evidence-native reasoning development environment for an evidence-bound artificial intelligence system, comprising: an interactive CWSG browser; a reasoning trace viewer; a synthetic evidence injection tool; a governance policy simulator; and an AIEP API mock layer.

7. A computer-readable medium carrying instructions for implementing the method of any preceding method claim.

Abstract

An evidence-native reasoning development environment for evidence-bound artificial intelligence provides five purpose-built tools: an interactive CWSG browser for world-state entity and causal edge inspection; a reasoning trace viewer displaying step-by-step evidence activation, traversal, simulation, and budget consumption; a synthetic evidence injection tool for constructing and injecting schema-valid test artefacts; a governance policy simulator showing APPROVE/REJECT/ESCALATE outcomes with rule-firing traces; and an AIEP API mock layer for offline development and unit testing. All tools operate at the semantic level of AIEP evidence and reasoning artefacts.
