As we are approaching the launch of our next product, Ghost Observatory, we would like to share some transparency about the project and why we founded the company.

Ghost Citadel was founded because some people couldn’t accept that math doesn’t lie.

While running operational studies at a large financial institution, our analysis of primitive data uncovered realities that leadership simply did not like. At first, they praised us to the skies, even calling us geniuses. However, a manager with zero previous leadership experience abruptly killed the project because the data harmed his personal relations with other leaders. Ironically, he left the company a few months after for "unknown reasons". They then offered us lesser roles, implying we lacked the skills — barking about "communication" while unable to define the word themselves.

This was the exact push we needed. We realized that in a large corporation, crossing the wrong person lands you on a blacklist. We walked away with a completely blank slate, leaving their primitive systems and leadership models exactly where they belonged. We strictly followed our NDA, taking absolutely zero code with us.

We then spent over six months building the future of time studies from scratch. Things that seemed impossible in the past are now reality.

Let us present Ghost Observatory.
It is a completely new, real-time process mining intelligence engine that pulls data from 150+ systems to turn complex operations into clear, undeniable evidence. Built for speed and trust, it helps teams detect risks and make confident decisions. We support 45+ calculations—from process mining and SLA checks to measuring workload balance using the Theil Index.
It runs on world-class libraries like Polars, DuckDB, SciPy, scikit-learn, and Apache ECharts.

The best part? It is free and partly open-source. pip install and boom. You are live, anywhere. It can deployed anywhere where it's allowed to install pip packages and run python.

Oh, and some final details! You can freely choose your AI model if you want to analyze the results, there is no "phone home" so you can feel safe to use it anywhere and finally, we have options to enable compliance with EU AI law Regulation (EU) 2024/1689 to ensure that everything is perfectly legal!

We plan to release the first alpha version this summer. Stay tuned!

We were working on the alpha version of our revolutionary new process mining and time studies Python tool, and we hit a strange wall: Zero bugs found.

We ran it through everything—Claude, Gemini, ChatGPT, DeepSeek, and Kimi. On paper, across every standard Western QA prompt, the code looked flawless. Smooth loops, clean abstractions, perfect compliance.

But standard tests assume a perfect world. Real enterprise systems run in a chaotic one.

To break the stalemate, we changed our strategy. We instructed the models to stop running standard QA and instead research and apply the latest, highly aggressive software testing methodologies used by Chinese tech giants like Huanfang, Huawei, and Meituan.

Suddenly, the AI stopped being polite. It targeted over 10 massive hidden vulnerabilities in our analytical engine, including:

The Data Ingestion Trap (Huanfang Quant Model): Our code assumed clean data streams. The Chinese test model immediately injected "Black Swan" data poisoning—corrupted schemas and dynamic NaN values—forcing us to abandon loose data layouts and lock down our pipeline using rigid, column-oriented structures like Polars and DuckDB.

The Thread-Freezing Threat (Huawei SRE Model): A heavy math computation in a localized subroutine was a ticking time bomb that could freeze the UI thread. We had to implement strict "Blast Radius" containment, isolating components behind error boundaries that degrade gracefully to the last known good state.

The Performance Illusion (Meituan Chaos Model): Our benchmarks relied on standard runtime averages, which easily mask micro-stutters. We replaced them with the Theil Index to dynamically measure the exact entropy and dispersion of operational latency.

Conclusion? Just because your AI says everything is perfect doesn't mean your architecture is bulletproof. Be open-minded. Ask tools like Gemini about the most innovative, non-Western software testing models, and then apply those rigid frameworks directly in Claude or Kimi.

New year. New legend.
Say hi to Ivar — the giant, furious gym cat currently imprisoned in the Kremlin basement.
Spoiler: he’s not staying locked up. 🔥
One of our next titles is about to get a whole lot angrier (and furrier).
