Validation Lab Overview

[!IMPORTANT] Non-Normative Document

This document is informative only.

SSOT Reference: This page is a Reference projection of Validation Lab governance documents.
Authority: Lab rulesets and evidence contracts are versioned and governed in the Validation Lab repository.

What is the Validation Lab?

The MPLP Validation Lab is an evidence-based adjudication system for evaluating MPLP lifecycle guarantees. It provides:

• Evidence-based verdicts for Lifecycle Guarantees (LG-01~05)
• Versioned rulesets for deterministic, reproducible evaluation
• Curated runs with reviewable adjudication proofs

Four Boundaries (Non-Negotiable)

1. Non-Certifying — Verdicts are evidence-based outputs, not official marks or endorsements
2. Non-Normative — Lab does not define protocol semantics; see MPLP Docs for specifications
3. No Execution Hosting — Lab does not accept uploads or run your code; you generate evidence locally
4. Deterministic Ruleset — Same evidence + same ruleset version = same verdict hash

Terminology Partition

Flow vs LG — Distinct Naming Spaces

• Flow-01~05 = Protocol Test Scenarios (defined in main repository tests/golden/flows/)
• LG-01~05 = Lifecycle Guarantees (Lab adjudication targets)

These are distinct and should not be conflated. Flows are test scenarios; LGs are what the Lab adjudicates.

Term	Definition	Role
Lifecycle Guarantee (LG)	Adjudication target (LG-01~05)	What the Lab evaluates
Evidence Pack	manifest + artifacts + timeline + snapshots	Input to adjudication
Ruleset	Versioned evaluation rules	Deterministic decision basis
Verdict	PASS / FAIL / NOT_EVALUATED / NOT_ADMISSIBLE	Output of adjudication
Conformance	Evidence meets versioned ruleset requirements	Evaluation conclusion (NOT certification)

Four Entry Points

MPLP uses a four-entry model. Each surface has a strict, non-overlapping role:

Entry	Role	URL
Website	Discovery & Positioning	mplp.io
Documentation	Specification & Reference	docs.mplp.io
Repository	Source of Truth	GitHub
Validation Lab	Evidence Adjudication	lab.mplp.io

Version Taxonomy

The Lab uses four distinct version prefixes:

Prefix	Name	Description
site-v*	Site Freeze	Website IA & public commitment
pack-v*	Evidence Pack Format	Pack structure version
ruleset-*	Ruleset Version	Adjudication rule version
rel-lab-*	Release Seal	Governance freeze tag

tip

When you see v0.x in Lab context:

• In /runs page → refers to pack format (pack-v0.2~v0.4)
• In Footer/Home → refers to site freeze (site-v0.5)
• In data/rulesets/ → refers to ruleset version (ruleset-1.0~1.2)

What the Lab Provides

✅ Evidence-based evaluation tools
✅ Self-assessment frameworks
✅ Lifecycle Guarantee (LG-01~05) verdict generation
✅ Schema validation utilities
✅ Reproducible, auditable verdicts

What the Lab Does NOT Provide

❌ Official certification or compliance marks
❌ Badges, seals, or rankings
❌ Execution hosting or runtime environments
❌ Implementation advice or adaptor recommendations
❌ Regulatory or legal guarantees
