Synthesis Citation Index: The HLRP Corpus Dependency Graph and Triadic Governance Architecture (HLDP)

Document 3 of 4 in the HLDP K₄ Governance Loop. Published as a coordinated drop 2026-04-27. The four documents form a closed mutual-citation graph (each cites the other three) with one apex Principal-of-Principles. Companion: HLRP #158 Synthesis Ledger v6 (10.5281/zenodo.19829505).

The four documents in reading sequence:

1. IE Operator Hierarchy (Principal-of-Principles, apex) — 10.5281/zenodo.19829498
2. Math Companion (formal apparatus) — 10.5281/zenodo.19829500
3. Synthesis Citation Index (SCI) (corpus dependency graph) — 10.5281/zenodo.19829504
4. Capstone — HLDP Doppler Radar (synthesis vantage; cancer apex) — 10.5281/zenodo.19807751

This document: Document 3 — Synthesis Citation Index (SCI). The corpus dependency graph rendered explicit. Every published HLRP paper (#1 → #170, plus sub-numbered #13.1, #13.2, and revision #115v2) indexed by HLRP # / title / DOI / role-class / IE-class binding / substrate / coupling direction. Substrate-attractor map (IE-001 → IE-007). Tier 1 watchlist predictions linked to substrate-paper provenance. Standing-protocol compliance log (three corpus-check failure modes documented v6 cycle). Two named sub-programmes (GCRP, Open Letter). Future researchers entering the corpus from any vantage can traverse to the dependency neighborhood.
