truesignal

TrueSignal's answer to that failure mode is structural: every connector's failure path is required, by a CI-enforced test suite, to return either a real cached item honestly labeledfallbackwith its real age, or nothing at all. There is no third path where data is invented. In exchange, TrueSignal covers a deliberately narrower surface than Crucix -- OSINT and security signals only, five official-API sources, no markets or air-traffic domains.

Does TrueSignal replace Crucix?TrueSignal covers only OSINT/security signals from five official APIs; Crucix also covers markets, air traffic, social feeds, and general news. If you need the wider domain coverage and can tolerate Crucix's five open, unfixed fabrication/staleness issues (cited above), Crucix still does more. If you specifically need a security/OSINT feed with a tested guarantee against fabricated or silently-stale data, that's what TrueSignal is for.

What happens if a source goes down?The connector either returns real cached data explicitly labeledfallback(with its exact real age infallbackAgeSeconds), or returns nothing. It never returns invented data or silently relabels old data as current. That guarantee is enforced bysrc/truesignal/provenance/no-fabrication.test.ts(22 tests, all passing) for every one of the 5 connectors.

Does this need an API key?Not to start. CISA-KEV and GDELT work with zero configuration. Cloudflare Radar, Reddit, and Telegram each need a free developer key or token --truesignal inittells you exactly which environment variables are still missing.

Does it send my data anywhere?No telemetry by default. Everything runs on your own machine using your own API keys; there's no account and no phone-home.

Is this the same team's hosted product?This repository is the free, self-hosted, MIT-licensed CLI and connector engine. It works completely standalone.

What is TrueSignal, in one line, and what's the actual differentiator?Per its own--helpoutput: "a provenance-first OSINT/security intelligence feed" that pulls from five official-API connectors (CISA-KEV, Cloudflare Radar, Reddit, Telegram, GDELT) and stamps every item with a real source URL, a real upstream timestamp, and an explicitliveorfallbackstatus. The differentiator isn't the connector list, it's the no-fabrication guarantee:src/truesignal/provenance/no-fabrication.test.tsand its Python equivalent (python/tests/test_no_fabrication.py) run on every push and pull request tomain(.github/workflows/ci.yml), asserting that no connector's failure path ever invents data.

What platforms and versions does TrueSignal run on?The npm package requires Node.js 18.17 or later (engines.nodeinpackage.json). The Python package supports Python 3.9 through 3.13 (pyproject.tomlclassifiers), and CI runs the Python test suite against both 3.9 and 3.13 on every push and pull request. Both CI jobs currently run onubuntu-latest; Node.js and Python are cross-platform runtimes, but macOS and Windows aren't separately exercised by this repo's CI today.
