Evidence-Based Evaluation

Validation Lab

Evidence Verdict Gateway for Institutional Integrity

Non-Certification & Non-Endorsement NoticeThis page provides an informational overview of the MPLP conformance model. It does not constitute certification, endorsement, or official verification.For formal definitions, see docs.mplp.io.

Validation Lab is Live

The Lab evaluates your evidence under versioned rulesetsand outputs a reproducible verdict hash + downloadable proof.

How It Works

INPUTEvidence Pack (generated in your environment)
EVALVersioned Ruleset (deterministic evaluation)
OUTPUTVerdict Hash + Proof JSON + Curated Adjudication Links

Determinism Guarantee: Same evidence + same ruleset = same verdict hash.

Four Boundaries (Non-Negotiable)

Non-Certifying

Verdicts are evidence-based outputs, not official marks or endorsements.

Non-Normative

Lab does not define protocol semantics. See MPLP Docs for specifications.

No Execution Hosting

Lab does not accept uploads or run your code. You generate evidence locally.

Deterministic Ruleset

Same evidence + same ruleset version = same verdict hash. Always reproducible.

Inside the Lab

In the Lab you will find three primary views — coverage, runs, and adjudication — each designed for reproducible, evidence-based review.

Step 1

Generate Evidence Pack

Run your agent locally and produce an MPLP-compatible evidence pack (via SDK or producer tooling).

Step 2

Verify Pack Integrity

Validate manifest + hashes before sharing or archiving the pack.

Step 3

Read Adjudications

Browse published runs and verdicts already curated in the Lab.

Step 4

Recheck Deterministically

Use ruleset version + evidence pack to independently verify any verdict_hash.

Coverage

Framework coverage status by lifecycle guarantee. Coverage reflects evidence maturity, not framework quality.

Live counts and verdict details are shown in the Lab.

Curated Runs

Published adjudication runs with evidence references and deterministic verdict_hash outputs.

Live counts and verdict details are shown in the Lab.

Adjudication

Reviewable proof packages with verdict hash, ruleset version, and evidence pack references.

Live counts and verdict details are shown in the Lab.

Coverage indicates evidence maturity, not framework quality, endorsement, or ranking.

Version Taxonomy

Validation Lab uses four distinct version prefixes. Do not confuse them.

3+1 Entry Model

MPLP uses a 3+1 entry model: 3 Primary (Website, Documentation, Repository) + 1 Auxiliary (Validation Lab). Each surface has a strict, non-overlapping role. The Repository is the sole source of truth.

Rulesets & Contracts

The Lab uses versioned rulesets and evidence pack contracts. Authoritative definitions are governed in the Validation Lab repository.

Versioned Rulesets

Deterministic evaluation rules (ruleset-*). Same evidence + same ruleset = same verdict.

v0.9 Capability: Ruleset diff reports now include deterministic explanations and reproducible command packs. This does not rank or endorse any implementation.

Evidence Pack Contract

Pack structure and format versioning (pack-v*). Portable, recheckable, auditable.
