5QLN Constitutional Legal Plugin

Platform: Anthropic Claude-for-Legal
Plugin ID: 5qln-constitutional-legal@claude-for-legal
Version: 0.1.0
Author: 5QLN Foundation
License: MIT

What This Is

A third-party external plugin that integrates the 5QLN Foundation constitutional governance framework into Anthropic's Claude-for-Legal ecosystem. It packages the 9-line Codex, the five-phase constitutional cycle (S→G→Q→P→V), the Membrane Protocol, dual-edition bylaws, corruption codes, and attestation discipline into eight skills that Claude can invoke.

What It Does

This plugin enables AI-assisted constitutional governance analysis under the 5QLN grammar. It does not make decisions. It does not sign anything. It does not replace legal counsel. It:

• Fetches and cryptographically verifies the canonical Codex at invocation time
• Runs constitutional analysis through the full S→G→Q→P→V cycle
• Audits membrane integrity — checks that K-side (AI analysis) and ∞₀-side (human authorization) remain properly separated
• Detects corruption — L1 (Closing), L2 (Generating), L3 (Claiming), L4 (Performing), V∅ (Incomplete)
• Cross-references editions — compares Human and AI/OS Edition bylaws for semantic equivalence
• Prepares attestation records — Tier-B seal records ready for Conductor Ed25519 signature (plugin never signs)
• Routes disputes through graduated escalation: CIO → Resonance Court → Chancery

Why It Exists

The 5QLN Foundation publishes a constitutional grammar — a 217-byte Codex with a fixed SHA-256 hash — that governs how an AI and a human collaborate on governance questions. This plugin makes that grammar operational inside the most widely used AI-for-legal platform, with cryptographic integrity guarantees at every step.

Every analysis operation begins by fetching the Codex from GitHub and verifying its SHA-256 hash. If the hash doesn't match — the plugin halts. There is no "trust me" path.

codex-verify (fetches at invocation time, computes hash, constant-time compare)
  │ PASS → proceed
  │ DRIFT → HALT — no downstream skill runs
  │
  ▼
All 6 analysis skills (constitutional-analysis, membrane-audit, corruption-detect,
  edition-cross-ref, cycle-attestation, dispute-route)

Design invariants:

• No copy of the Codex ships inside the plugin
• No AI signing — the Conductor holds the Ed25519 key offline
• Fail-closed — hash mismatch halts every downstream skill
• Tier separation — working register, sealed record, and public surface are distinct
• 14/14 validation checks passed (see VALIDATION_REPORT.md)

Integration Path

This repository is the canonical source for the plugin. The integration into Anthropic's claude-for-legal follows this path:

1. This repo (qlnlife/5qln-constitutional-legal) — canonical development + maintenance
2. Fork/PR into anthropics/claude-for-legal — copy into external_plugins/5qln-constitutional-legal/
3. Register in root marketplace.json — add the registration block from .claude-plugin/marketplace.json
4. Users install via /plugin install 5qln-constitutional-legal@claude-for-legal

See PR_DESCRIPTION.md for the full PR narrative and INTEGRATION.md for technical integration details.

Relationship to the 5QLN Foundation

The plugin does not contain the Codex. It fetches the Codex from the Foundation repository at invocation time and verifies the SHA-256 hash before any operation. If the Foundation amends the Codex (v2), the plugin's references/codex-reference.md is updated, the new hash is configured via cold-start-interview, and the codex-integrity-watcher agent detects any unannounced drift.
