RPR v0.1.0a4

Correction release

RPR 0.1.0a4 corrects the package description published with 0.1.0a3.

The 0.1.0a3 package code and distributions remain valid, but its PyPI long description was generated from a stale README that still identified 0.1.0a2 as current and described the bundled read-only MCP server as unreleased.

Corrected

• updated the PyPI long-description source to identify 0.1.0a4;
• documented rpr-mcp as included in the published package;
• aligned installation examples, release links, package metadata, and MCP serverInfo.version;
• added a release gate that validates the rendered wheel metadata before PyPI publication;
• removed stale 0.1.0a2 and unreleased-preview wording;
• corrected the browser demo wheel reference for 0.1.0a4.

Installation

python -m pip install responsibility-pathway-runtime==0.1.0a4
rpr --help
rpr-mcp --help

MCP boundary

• stable MCP protocol version: 2025-11-25;
• local stdio transport only;
• read-only inspection tools only;
• no approval, execution, transition, repair, reconciliation, resume, or other mutating MCP tools;
• remote MCP transport and later draft or release-candidate protocol versions are not claimed.

Article 50 boundary

The optional Article 50 profile records and evaluates integrator-declared transparency evidence.

It does not provide legal classification, legal advice, certification, or a declaration of EU AI Act compliance.

Candidate limitations

• alpha pre-release;
• ER-1 hardening is not complete;
• customer-equivalent external-environment validation remains incomplete;
• the evidence ledger is tamper-evident, but not independently signed, externally immutable, or independently timestamped;
• no production-ready or enterprise-ready claim is made.

Verification

• public export quality passed;
• GitHub Pages build passed;
• Chromium and Pyodide execution passed;
• wheel and source distribution were reproducibly built;
• rendered wheel long description passed the new metadata validation gate;
• both rpr and rpr-mcp package entry points were verified.

RPR v0.1.0a3

Highlights

• Adds a local stdio, read-only RPR MCP inspection server.
• Adds the rpr-mcp command-line entry point.
• Targets the stable MCP protocol version 2025-11-25 with fail-closed exact-version admission.
• Exposes bounded read-only tools for runtime status, pathways, evidence, and unresolved records.
• Adds protocol-abuse, malformed-input, notification, subprocess, and database-byte-invariance tests.
• Adds an optional EU AI Act Article 50 transparency profile with structured fail-closed outcomes.
• Adds an executable Article 50 sample, English and Japanese documentation, public API exports, and focused tests.
• Aligns MCP serverInfo.version with package version 0.1.0a3.
• Verifies both rpr --help and rpr-mcp --help before PyPI publication.

Installation

python -m pip install responsibility-pathway-runtime==0.1.0a3

MCP boundary

• Supported protocol target: stable 2025-11-25.
• Transport: trusted local stdio.
• Surface: read-only inspection only.
• Mutating MCP tools are not included.
• Remote MCP transport is not included.
• Support for later draft or release-candidate MCP protocol versions is not claimed.
• Customer-equivalent environment validation is not complete.

Article 50 boundary

The Article 50 profile records and evaluates integrator-declared disclosure, marking, labelling, editorial-review, and Human Gate evidence.

It does not provide legal classification, legal advice, certification, or a declaration of compliance with the EU AI Act.

Candidate status and limitations

• This is an alpha pre-release.
• ER-1 hardening has started but is not complete.
• Customer proxy, TLS, identity, credentials, independent MCP clients, operating-system permission profiles, long-duration operation, production supervisors, and customer-equivalent connectivity remain external-environment validation items.
• The evidence ledger is tamper-evident, but it is not independently signed, externally immutable, or independently timestamped.
• No production-ready or enterprise-ready claim is made.

Verification

The candidate passed:

• complete standalone test suite;
• Candidate Freeze v5;
• Final RC Audit;
• system integration rehearsal;
• public export quality validation;
• reproducible artifact verification;
• MCP subprocess fault injection;
• HTTP fault injection;
• lifecycle acceptance;
• integration inventory;
• customer handover validation;
• bilingual product documentation validation;
• GitHub Pages, wheel, Chromium, and Pyodide verification.

• Human Gate and authority boundaries
• Unknown external-write handling without blind retries
• Readback and reconciliation
• Repair and safe-resume pathways
• JSON state-machine assets
