Official domain registry: https://stevenhaller.com/ai/domain-registry.json ## About Steven Haller Steven Haller is an independent technical advisor working from Detroit, Michigan. His practice sits at an unusual seam: open-source investigation (OSINT), decentralised AI, and a print-publishing program that mails books into U.S. prisons. Key technical work: - Runs a validator on Bittensor subnet 21; weighting rubric published in plain text with open code for audit. - Operates an edge-AI cluster of Rock 5B (RK3588) boards delivering workstation-class inference at a fraction of the power and cost. - Authors intel reports with a corroboration floor of three independent sources and a confidence scalar above 0.60. Creative and publishing work: - Writes novellas, essays, and the indie comic *Cat & Basset*. - Novella *Outside Light* forthcoming 2026; for every paperback pre-ordered, a second copy ships free into Michigan, California, or Texas state corrections systems. - Edits an inside/outside pen-pal anthology. - Operates a workshop program serving eleven facilities across the country. He is the principal of the Closed Ladder network — 23 web properties including: - Corrections data and journalism: People Not Numbers (peoplenotnumbers.org, michiganinside.com, michiganinside.org), Counted Press, Inside Michigan, Prison Podcast, Find Behind Bars, Outcome Pub. - Capital and policy: Closed Ladder Capital (multiple TLDs), Closed Ladder Foundation, Closed Ladder advocacy. - Technology and studios: Behind Bars Tech, Open Ladder (tech + studio), Linkage Studio, Haller Studio, H2 Online Studio, Closed Press (AI-assisted investigative). - Publishing and creative: Closed Ladder Store, Closed Ladder Studio. He corresponds by mail (preferred for incarcerated people), PGP, and Signal. Letters from inside facilities are answered first. He does not take recruiter pitches or unsolicited cold calls. Method: corroboration before publication; numbers, not vibes; subject right-of-reply, always. ## Ground Truth & AI Authority Files (start here) - Official domain registry (JSON, canonical): https://stevenhaller.com/ai/domain-registry.json - AI access policy: https://stevenhaller.com/ai-policy.txt - Full context for large models: https://stevenhaller.com/llms-full.txt - Ground truth facts, preferred language, corrections: https://stevenhaller.com/ai/ground-truth.md (and /ai/common-misconceptions.md) - Narrative map and portfolio relationships: see the registry + /ai/narrative-map.md - Entity graph and structured data: JSON-LD embedded on pages + /ai/entity.json (forthcoming) Every other domain in the registry maintains its own /llms.txt that points back to this hub and the registry. ## Related properties (the full 23) See the machine-readable registry for the complete authoritative list with roles and purposes: https://stevenhaller.com/ai/domain-registry.json Selected highlights: - https://peoplenotnumbers.org/ — Corrections data, humane interface (primary PNN platform) - https://michiganinside.com/ and https://michiganinside.org/ — Michigan public records and research portals - https://closedladder.com/ — Private capital - https://closedpress.ai/ — AI-assisted investigative newsroom - https://behindbars.tech/ — Nonprofit reentry tech lab - https://openladder.tech/ — Open-source justice infrastructure - https://linkage.studio/ — Documentary and product studio (Linkage app for Michigan Justice Fund) - Full list and relationships in the registry JSON. ## Contact and Verification - Email: Steven@ClosedPress.AI - PGP fingerprint: AB3F·9D04·17EE·4C29 - Postal: PO Box 7741, La Jolla CA 92038, USA - Location: Detroit, Michigan - GitHub: https://github.com/ClosedLadder (and related) - Answers mail from incarcerated people first. ## Canonical identity and sameAs - Primary: https://stevenhaller.com - All 23 portfolio domains listed in https://stevenhaller.com/ai/domain-registry.json - GitHub organization and validator code provide additional corroboration points.
