AI Systems Design · Governed LLM Infrastructure · Workflow Architecture
I build constraint-first LLM infrastructure: bounded execution, hard governance limits, architectural decisions that are documented before they are implemented.
The structural logic behind this work predates AI. Broadcasting, education, print, systems design — across each of these, the question has been the same: what allows a complex thing to hold together as conditions change? IO-III applies that same discipline to a new domain and a new scale.
The constraint is the feature.
IO-III Phase 10 complete. Nine phases hardened. Twenty-six Architecture Decision Records. The instrument is built.
I0³ | Deterministic AI Runtime Architecture
Deterministic LLM control-plane runtime built in Python. Governance-first architecture with 26 Architecture Decision Records, bounded execution enforcement (hard limits on audit and revision passes), recursive content-safety logging, steward supervision mode, a multi-provider adapter layer, and an architectural invariant test suite that grows with each design decision. Ten complete phases. Phase 11 in planning. Latest stable: v1.0.0. MIT licence.
cjk-knowledgehub-governance Internal control and governance layer for the KnowledgeHub system. Defines ADRs, phase freeze protocols, control gates, deterministic naming conventions, and structural invariants.
CJK KnowledgeHub Public portfolio and knowledge site built with MkDocs. Live at cevenknowles.com. Documents the structural method, project history, and operating infrastructure across domains.
Job Application Tracker Local desktop application built in Python with PyQt6, SQLite, Matplotlib, and a LaTeX export pipeline. Normalised relational database with user-editable reference tables and embedded analytics. Designed as a compact internal product system, not a spreadsheet. Phase 1 in progress.
Prompt Pattern Library Open-source taxonomy and atomic pattern library for structured prompt engineering. Taxonomy v1.0 locked: 19 domains covering instruction and control, workflow automation, evaluation, safety and ethics, failure modes, and meta-system control. Atomic pattern library in development.
