Lacefield Research · System architecture

One engine.
Seven domains.

The Lacefield Adaptive System is domain-independent. The same core architecture that tracks schema floor in education tracks operator readiness in heavy equipment and driver readiness in autonomous vehicles. The primitives transfer. The domains change.

Domains

Where the engine
has been deployed.

The architecture was built and validated in education — the most constrained environment possible, which proved it could run at high fidelity on minimal resources. Each additional domain applies the same primitives with domain-specific profiles and circuit breaker thresholds.

● Live — current

Education

GED, algebra, calculus, adult learning. Schema tracing, misconception IDs, 80/20 calibration. 7 years of direct classroom research. Validated against 130+ student TABE dataset.

◌ Spec built

Trading

Trading schema floor, market condition profile, execution circuit breaker, "Guess Why" feature. Distinguishes schema errors from execution errors in trading decisions.

◌ Spec built

Heavy Equipment & Industrial

Operator skill floor, environment context profile, microsleep detection via joystick jitter, hard stop protocol. Crane, long-haul trucking, excavator domains specified.

◌ Spec built

Elite Athletic Training

Physiological capacity floor, environmental athlete profile, 3% form latency circuit breaker, acute:chronic load ratio monitoring. Strength, endurance, skill acquisition domains.

◌ Spec built

Autonomous Co-Pilot

Driver readiness floor, vehicle environment profile, 200ms reaction time baseline, handoff decision engine. Inverts the current AV safety paradigm — checks driver before requesting control transfer.

○ Identified

Recovery & Rehabilitation

Recovery schema floor, life context profile, harm reduction calibration, sobriety momentum tracking. Addiction recovery, physical rehabilitation, mental health support contexts.

○ Identified

Medical & Clinical Training

Procedural schema floor, clinical context profile, patient safety circuit breaker. Surgical training, emergency medicine, diagnostic reasoning skill development.

Core architecture

The primitives that
transfer across every domain.

These are not metaphors — they are the same data structures, the same engine logic, the same circuit breaker protocol in every domain. The domain-specific content (tier maps, misconception libraries, scenario gap flags) changes. The architecture does not.

The four profiles — per domain
P1 — Dynamic State Profile
What the human actually knows / can do
Education: DLP — schema floor, wrong schema flags. Industrial: DOP — skill floor, bad habit flags. Athletic: DAP — capacity floor, compensation flags. AV: DDP — route schema mastery, scenario gap flags.
P2 — Context Profile
What the environment is doing to the human
Education: SCP — career, goals, framing anchors. Industrial: ECP — cabin temp, shift length, wind. Athletic: EAP — altitude, sleep debt, HRV. AV: VEP — weather, traffic, passive monitoring duration.
P3 — Calibration Engine
Task assignment matched to current envelope
Education: ACDE — 85/15 growth-edge targeting. Industrial: AODE — task complexity ceiling. Athletic: AATE — session load design. AV: ACPE — handoff eligibility calculation.
P4 — Circuit Breaker
Catches degradation before the failure
Education: destructive frustration detection — accuracy collapse. Industrial: CEP — joystick jitter, reaction time. Athletic: CEP — 3% form latency. AV: CEP — 200ms reaction delta, readiness hold.

Available for work — research collaboration, ed-tech development, domain licensing, consulting. The architecture is built. The question is which domain ships first.
