Release Proof

Martenweave Core v0.9.0 is the current supported public source and PyPI release.

• GitHub Release: v0.9.0
• PyPI package: martenweave-core 0.9.0
• Core repository: https://github.com/metalhatscats/martenweave-core
• PyPI project: https://pypi.org/project/martenweave-core/

The core remains backend-first: a Python package, CLI, local API, MCP-ready backend, canonical Markdown/YAML files, validation, generated indexes, and reviewable PatchProposal workflows. There is no hosted UI in the core release.

Martenweave Core is open-source software licensed under Apache License 2.0. It may be used, modified, embedded, and distributed, including for internal and commercial purposes, subject to the license terms. Optional commercial services include implementation, private SAP/MDM domain packs, enterprise validation packs, integrations, training, hosted Workbench work, and support.

Change log

0.9.0 — 2026-07-29

• martenweave start creates a local, manifest-backed readiness workspace from one CSV, XLSX, XML,

or JSON file. It performs format preflight and profiling, records deterministic readiness findings with evidence, writes a readable report, and exposes the connected local Workbench flow.

• The installed PyPI artifact was verified in a clean Python 3.11 environment for CSV, XLSX, XML,

JSON, unsupported-format rejection, packaged templates, no-AI operation, and Workbench assets served from the installed package.

• The release suite passed full Python tests, lint and formatting checks, frontend unit and browser

checks, package build, release preflight, and the installed-artifact smoke flow.

• Provider configuration remains optional and provider-neutral: local diagnostics redact secrets,

optional AI creates reviewable PatchProposal objects only, deterministic validators verify, and a human remains required for approval.

0.8.0 — 2026-07-25

• Pilot Proof workflow: preflight a realistic SAP mapping workbook, bootstrap a proposal-only

model, assess deterministic findings, review them, and produce client-ready reports without changing canonical model files automatically.

• Mapping-workbook comparison produces JSON, HTML, and XLSX evidence for changed mappings,

source/target fields, conditions, transformations, owners, statuses, validation rules, decisions, and matched canonical endpoint impact.

• Assessment packages now include a standalone executive HTML report, findings workbook,

machine-readable findings, evidence manifest, review pack, and Workbench workspace descriptor.

• The regression corpus exercises ten irregular Excel structures, including shifted/merged

headers, hidden sheets, formulas, repeated tables, multilingual and inconsistent columns, colour-only statuses, large files, and split source/target sheets.

0.7.1 — 2026-07-25

• Fix: schema imports of contracts with repeated element names across message structures no

longer fail part-way at proposal apply; duplicate creates are deduplicated and flagged at validation time.

• The Workbench groups create-heavy proposals (schema imports) by object type in preview and

detail review.

• The SAP BP reference example now includes a synthetic WSDL contract and its imported

interface/message lineage slice.

0.7.0 — 2026-07-25

• martenweave schema inspect|import turns local machine-readable contracts (JSON Schema,

OpenAPI, OData EDMX, WSDL, XSD, IDoc/WE60 documentation, CDS metadata, Integration Suite exports, Migration Cockpit templates, field catalogues) into normalized evidence and reviewable proposals that can create Interface, InterfaceEndpoint, MessageType, and SchemaNode lineage with recorded source provenance. Nothing is applied without human approval.

• martenweave domain-pack build|validate|diff manages built-in reference domain packs locally.
• Pilot preflight, bootstrap, and migration assessment now emit governed workbook suggestion

artifacts with a protected review workbook roundtrip.

• The agent-loop command can accept a mapping workbook as preflighted, metadata-only evidence;

the loop remains proposal-first and never applies or approves model changes.

• The Workbench labels interface-lineage object types distinctly in object and lineage views.

0.6.2 — 2026-07-24

• Workbench imports now inspect CSV/XLSX evidence before profiling or proposal preview, showing

sheet/column interpretation and safety warnings without treating evidence as canonical truth.

• The reusable SAP migration/MDM scenario matrix and deterministic workbook evidence tests were

added to Core.
