I turn ambiguous systems into inspectable tools, tests, and handoffs across agent infrastructure, evaluation, developer tools, graphics, technical operations, and physical field work.
Zain Dana Harper and Zentropy Labs are the front door. Flywheel is the main agent platform inside a broader workshop that also includes independent security systems, compilers, evaluation tools, graphics engines, preservation work, research, and field experience. Each project is described by what its code does, not forced into one product hierarchy.
Available for paid work: full-time, contract, project, onsite, hybrid, or remote. Based in Seattle, Washington.

| Path | Where I fit | Start here |
|---|---|---|
| Technical and evaluation | Agent and model evaluation, developer infrastructure, systems integration, CI, security testing, technical support, and documentation. | Engineering path |
| Public, union, and field | Public service, ports, facilities, parks and grounds, arboriculture, client operations, scheduling, safety judgment, and physical work. | Public-service and field path |
| Education and research | Fellowships, labs, research operations, mentorship, continued learning, open-source work, and evidence-centered technical writing. | Research and education |
These results show the work surviving another maintainer's scope and review.
- AgentFence PR 261: an owner-approved and merged Go engine optimization with deterministic rule selection, allocation coverage, and green cross-platform checks.
- Free Law Project PR 820: approved and merged documentation for running the fast DB-free test suite.
- Mergewarden PR 107: replay fixtures for reusable-workflow pinning, revised after owner review, approved, merged, and CI-checked.
The current verified release of Flywheel v0.3.10: a model-neutral agent workbench for routing, gated tool use, evaluation lanes, receipts, memory, context, and reproducible workflows. It is a major product, not a label for everything else in the workshop.
| Family | Representative public work |
|---|---|
| Agent execution and memory | Flywheel, Forum, Relay, Mneme, Plexus |
| Evaluation and verification | Terminal State Fixtures, Crucible, Emet, Bounds |
| Security and privacy | Shipped public work: Phantom. Controlled-private systems with public capability descriptions: Array, Seed, Sofer, Isomorph, Bounds, ORCA and Gate |
| Developer infrastructure | BuildLang, Index, Gather, Chorus |
| Graphics and runtime systems | RAW, SkyrimBridge, Studio Engine, Truth ENB, Elder ENB |
| Preservation and retro systems | Retro Engine, Engine Revival, BRender Archival |
| Research and education | Learn, research records, publications, and measured analytics |
Phantom v1.1.0 ships reversible hardware-identity privacy controls for Windows and Linux. It covers Layer 2 identity surfaces. Kernel and firmware layers are modeled but not shipped end to end. Use is limited to machines the operator owns or is expressly authorized to test.
Phantom is shipped public work. Array, Seed, Sofer, Isomorph, Bounds, ORCA, and Gate are controlled-private systems with public capability descriptions. They are not public releases or downloads.
The security catalog documents each system separately. Phantom changes and restores hardware-identity surfaces. Array coordinates approval-gated offensive campaigns. Seed runs assessment and detection-engineering modules. Sofer coordinates agents, models, probes, and multi-stage workflows. Isomorph tests AI classifier and refusal behavior at authorized inference boundaries. Bounds checks actions, observations, and releases. ORCA manages private findings and reports; Gate makes fail-closed integration and release decisions. Public pages describe each system's job, evidence, maturity, and limits. Targets, credentials, live payloads, client data, and engagement-specific findings stay in approved private or embargoed channels.
The lab follows play → preserve → verify while keeping each proof boundary clear:
- Retro Engine is the interactive browser studio for owned pixel, palette, shader, and CRT experiments.
- Engine Revival v0.1.0 is the public preservation and restoration-evidence spine.
- BRender Archival v0.1.1 carries the specific BRender restoration record. Generic retro visuals are not presented as BRender evidence.
Map the real state, build the missing surface, verify it, and leave an artifact another person can inspect and maintain.
