# Explore the question. Inspect the evidence. X6 Spectral Astrolabium is an open research hub for signals, graphs and causal orders. Start with a browser experiment, explore a research module, or reproduce a finite reference calculation.

Exploratory software prototype, not validated quantum gravity. Architecture v0.1 remains a research draft; CQG-01–08 have not been executed as a complete test campaign. - [Open the Causal-Set Lab →](https://thomasmgfeller.github.io/x6-spectral-astrolabium/app/rax-cqg-lab.html) - [Download benchmark package 0.2.0 ↓](https://thomasmgfeller.github.io/x6-spectral-astrolabium/docs/research/rax/cqg-benchmark-v0.2.0/RAX_CQG_Benchmark_v0_2_0.zip) - [Checks, sources and limitations →](https://thomasmgfeller.github.io/x6-spectral-astrolabium/modules/rax-cqg-benchmark.html) - [Read the architecture · PDF, 19 pages →](https://thomasmgfeller.github.io/x6-spectral-astrolabium/docs/research/rax/cqg-v0.1/RAX_CQG_Forschungsarchitektur_v0_1.pdf) - [Markdown and sources on GitHub →](https://github.com/thomasmgfeller/x6-spectral-astrolabium/blob/main/docs/research/rax/cqg-v0.1/ARCHITECTURE.md) - [Download the Word document ↓](https://thomasmgfeller.github.io/x6-spectral-astrolabium/docs/research/rax/cqg-v0.1/RAX_CQG_Forschungsarchitektur_v0_1.docx) ## More tools & references Launch either browser application above. These starting points lead to the relevant instructions, prerequisites and documented checks. ### Shared workflow LOCAL INSTALLATION. Run signal, spectral and RAX jobs locally, export results and replay calculations. Follow the setup and launch instructions. [Set up the local workflow →](https://thomasmgfeller.github.io/x6-spectral-astrolabium/modules/integration.html) ### Sagnac data import ASTROLABIUM · TAB 07. Inspect synthetic examples and SGNCv007 recordings in the Astrolabium. The local bridge requires Python; this does not demonstrate optical device control. [Open Sagnac instructions →](https://thomasmgfeller.github.io/x6-spectral-astrolabium/modules/sagnac-import.html) ### Reference edition & test suite LOCAL REPRODUCTION. Versioned reference packages and ten documented offline reports. Follow the download, prerequisite and reproduction instructions. [Open the reference edition →](https://thomasmgfeller.github.io/x6-spectral-astrolabium/modules/reference-edition.html) ### Edge signal task LOCAL NODE.JS EXAMPLE. Run, export and replay a bounded signal task locally. An executable reference example for getting started with Edge workflows. [Explore the Edge example →](https://thomasmgfeller.github.io/x6-spectral-astrolabium/modules/edge-reference.html) ## Understand What is being studied, and what do the results actually say? A plain-language introduction to the research and its limits. [Understand the project →](https://thomasmgfeller.github.io/x6-spectral-astrolabium/guide/#understand) ## Try Explore signals and graphs in the Astrolabium or compare reference filters in Signal Lab. Synthetic examples show results and counterexamples. [Run a first experiment →](https://thomasmgfeller.github.io/x6-spectral-astrolabium/guide/#try) ## Verify Follow pinned sources, reproduce documented calculations and inspect the next acceptance gate. Negative results remain visible. [Reproduce and review →](https://thomasmgfeller.github.io/x6-spectral-astrolabium/guide/#verify) ## Lorentzian spectral geometry The complete exact test of 2,045 seven-element causal orders refutes the two-moment H7 hypothesis: two nonisomorphic pairs remain. Inspect all counterexamples and reproduce the separate enumeration and algebra checks. This finite result does not establish a physical theory. ## Read the scope with the result This is experimental research software. A passing software test is not physical validation. Hardware qualification, independent external replication and industrial performance qualification remain separate open tasks. - [Signals & validation](https://thomasmgfeller.github.io/x6-spectral-astrolabium/modules/signal-lab.html): Synthetic signals, reference methods, replayable evidence. - [Spectral graph references](https://thomasmgfeller.github.io/x6-spectral-astrolabium/modules/x6-qe.html): Exact finite examples and limits of spectral distinguishability. - [RAX · relational research](https://thomasmgfeller.github.io/x6-spectral-astrolabium/modules/rax-programme.html): Predictive reductions, competing models and falsification. - [Photonics & control](https://thomasmgfeller.github.io/x6-spectral-astrolabium/modules/acvm-optical.html): Software references and planned physical acceptance tests. - [Industrial data pilot](https://thomasmgfeller.github.io/x6-spectral-astrolabium/modules/industrial-pilot.html): A bounded laboratory-data feasibility study with explicit limits. - [NQK research dossier](https://thomasmgfeller.github.io/x6-spectral-astrolabium/modules/nqk.html): A separate research direction with incomplete reproduction archives. 39 modules are described in the register dated 2026-10-16. The register records source locations and evidence; it is not a live qualification badge. The configured research-agent window includes Sunday, 18 October 2026. The exclusive cutoff below is a schedule limit, not evidence of execution. After this cutoff the window is closed. 2026-10-19T00:00:00+02:00
