Abstract This paper describes a production pipeline for detecting and removing AI writing signatures from manuscripts before publication. The pipeline targets Bahasa Indonesia and English nonfiction prose. It includes a curated pattern library (30+ signatures), a regex-based detector, an auto-fixer that preserves document formatting, an iterative detect-fix-redetect loop, a voice consistency checker, and a pre-publication quality gate. The pipeline has been used in production across 558+ published titles to achieve a target AI signature score of zero at distribution time. The contribution is not novel detection theory but the discipline of treating zero-signature as a hard publication gate rather than a soft preference, and the explicit construction of a Bahasa Indonesia AI signature library, which is rare in the literature. What this deposit contains paper.md — the methodology paper (the citable scholarly artifact) supplementary.zip — bundled working source code for 8 component workflows covered by this paper, each with its own README, Python source, configuration, sample input, CITATION.cff, and LICENSE README.md — entry point CITATION.cff — machine-readable citation LICENSE (MIT for code) and LICENSE-DOCS (CC BY 4.0 for documentation) Production Results Across 558+ published titles: 100% of distributed titles pass the AI signature gate (score = 0) at compile time. Average detect-fix iterations to reach zero: 2.4. Most common manual-review patterns: rhetorical question clusters, staccato triads, ‘Bayangkan’ openers in originally hand-written drafts that absorbed AI rewrites. Zero customer reports of ‘this reads like AI’ across distribution channels with public review surfaces. Limitations The pattern library is finite and grows. New AI tells appear with new model releases. The library is a living document, not a finished one. The detector is regex-based. Patterns with semantic structure (e.g. ‘rhetorical questions clustered to evade individual matching’) are partially addressed by cluster regex but ultimately need human review. Bahasa Indonesia coverage is stronger than English coverage simply because this author writes more in BI; English patterns reflect a smaller corpus. Reproducibility All eight components are released as MIT-licensed source with the pattern library. The pattern library itself is a JSON file (CC BY 4.0) and may be forked, extended, or merged into other quality-control pipelines.
