Validation Lab
Evidence Verdict Gateway for Institutional Integrity
Validation Lab is Live
The Lab evaluates your evidence under versioned rulesetsand outputs a reproducible verdict hash + downloadable proof.
How It Works
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.
Generate Evidence Pack
Run your agent locally and produce an MPLP-compatible evidence pack (via SDK or producer tooling).
Verify Pack Integrity
Validate manifest + hashes before sharing or archiving the pack.
Read Adjudications
Browse published runs and verdicts already curated in the Lab.
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.
Browse Coverage →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.
Open Adjudication →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.

Authoritative source: Repository (schemas/tests/governance). Lab provides adjudication only. View Lab →
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.

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