MPLP Validation Lab

Evidence-based verdicts for MPLP lifecycle guarantees (Golden Flows), under a versioned deterministic ruleset.

---

Upstream Truth Source

This repository is a governed projection of the MPLP Protocol. All schemas, invariants, and rulesets are derived from:

Property	Value
Upstream Repo	Coregentis/MPLP-Protocol
Pinned Commit	See UPSTREAM_BASELINE.yaml
Protocol Version	MPLP v1.0.0 (Frozen)

Warning

Validation Lab does NOT define protocol semantics. It evaluates evidence against versioned rulesets derived from the upstream truth source.

---

Four Boundaries (Non-Negotiable)

Boundary	Description
Non-certification / Non-endorsement	No badges, rankings, or official compliance marks
Non-normative	Lab does not define protocol semantics; it evaluates evidence only
No execution hosting	Lab does not run your code; you provide evidence packs
Deterministic ruleset	Same evidence + same ruleset = same verdict

Protocol Substrates (MCP/A2A/ACP) — Non-Semantic Adjudication

Important

For substrates with type: protocol (e.g., MCP, A2A, ACP):

• The Lab adjudicates MPLP evidence produced via this transport/integration path.
• The Lab does NOT adjudicate the protocol's semantic correctness.
• Any mention of "compliance", "certification", "ranking", "accreditation", or "endorsement" is out of scope.

Version Taxonomy

This repository uses four distinct version types. Do not confuse them:

Type	Prefix	Current	Description
Site Freeze	site-v*	site-v0.5	Website information architecture and public commitment
Evidence Pack Format	pack-v*	pack-v0.2~v0.4	Evidence pack structure and field requirements
Ruleset	ruleset-*	ruleset-1.0~1.2	Adjudication decision rules and requirements
Release Seal	rel-lab-*	rel-lab-0.5	Versioned governance seal for a frozen release

Note

When you see v0.x in this repository:

• In /runs page sections → refers to pack format (pack-v0.2, pack-v0.3, pack-v0.4)
• In Footer/Home → refers to site freeze (site-v0.5)
• In data/rulesets/ → refers to ruleset version (ruleset-1.0, 1.1, 1.2)

---

Projection Authority

Website pages are projections of Single Sources of Truth (SSOT). Governance documents MUST NOT embed live registry tables.

SSOT File	Authority
data/curated-runs/substrate-index.yaml	Substrate registry
export/curated-runs.json	Consumer export contract
governance/LIFECYCLE_GUARANTEES.yaml	LG-01~05 definitions
data/rulesets/*/manifest.yaml	Ruleset definitions
governance/releases/release-index.yaml	Release seals

Important

Pages load from SSOT at build time. If a page's data differs from SSOT, the page is wrong.

v0.9.0 — Ruleset Diff Enhancement (MUST-3) — SEALED

• Seal (evidence closure): governance/seals/DIFF-ENHANCEMENT-SEAL.v0.9.0.md
• UI: /rulesets/diff (prefers .enhanced.json, falls back to v0.8 frozen artifacts)
• Export artifacts:
  • v0.8 (frozen): export/ruleset-diff/*/diff.json and export/ruleset-diff/index.json
  • v0.9 (parallel): export/ruleset-diff/*/diff.enhanced.json and export/ruleset-diff/index.enhanced.json

Non-endorsement boundary: Diff reports explain ruleset changes only. They are not certification, endorsement, or ranking of any framework/vendor/substrate.

v0.9.1 — UI Facets + Repro Pack — SEALED

• Seal: governance/seals/UI-FACETS-REPROPACK-SEAL.v0.9.1.md
• UI Facets: Domain and change_type filtering on detail page
• Repro Pack: export/ruleset-diff/*/repro-pack.json (rp-1 profile)
• Commands and hashes for deterministic reproduction

v0.9 Series Summary: v0.9.0–v0.9.1 upgrades ruleset diff from "generatable" to "explainable + reproducible + referenceable" while preserving the v0.8 frozen evidence chain.

v0.12 Sustainability Release: Establishes the representational baseline (MCP) and solidified SOP gates. The project is now in Maintenance Mode. SEAL-v0.12.1

---

---

🛡️ Institutional Reference & Audit (v0.12.1)

• Canonical Anchor: SEAL-v0.12.1
• Immutable Tag: vlab-v0.12.1-institution
• Audit Routine: npm run heartbeat (Verifies gates + records logic consistency)
• Status: LOCKED/STATIONARY. Behavioral expansion is strictly versioned in v0.13.0+.

Refer to the Dormancy Notice and Maintenance Runbook for procedures.
