Public evidence layer: protocol specs, proof gallery, regulatory mappings, API contracts.
Part of CueCrux. Where outsiders can verify claims without accessing the machinery.
ResearchCrux is the public evidence and protocol layer for the CueCrux platform. It contains protocol specifications, living benchmark evidence, proof galleries, and published API/MCP contracts, all generated from or grounded in the platform itself.
VaultCrux is infrastructure. CueCrux is the Reasoning OS. ResearchCrux is where outsiders can verify claims without accessing the machinery.

This repository contains no runnable infrastructure. Evidence is generated from canonical audit runs using the generation scripts in this repo:
npm install
npm run generate # regenerate all evidence from source
npm run ledger:generate # benchmark ledger only
npm run proof:generate # proof gallery only
npm run contracts:generate # API/MCP contract docs onlyThe benchmark suite methodology and canonical results are included in audit-source/ (MIT).

Corpus: 1074 unique docs, 462 queries, 12 categories. LLM: gpt-4o-mini (OpenAI). Schema: Receipt schema 1.1 (llmModel + llmRequestId hash-bound).
Key metrics across 5 canonical runs:
| Category | Metric | Range | Target |
|---|---|---|---|
| Cat 2 (Format-Aware Citation) | avg_citation_recall | 0.633-0.693 | >=0.50 |
| Cat 8 (Proposition Precision) | precision_at_1 | 0.963 (5x) | >=0.80 |
| Cat 11 (Chunking Stress) | broad_recall | 0.927 (5x) | >=0.70 |
| Cat 12 (Hard-Negative Overlap) | parent_child_recall | 1.000 (5x) | >=0.80 |
Phase 7.4 adds LLM metadata binding (schema 1.1) to CROWN receipts. Zero retrieval code changed. Cat 7, 8, 11, 12 are perfectly deterministic across all 5 runs. Cat 5 receipt chain 10/10 intact (schema 1.1 validated).
