Apple Silicon / on-device
Local model iteration for teams and individual developers.
Device/runtime setup notes.
Security
Security is delivery structure, not an add-on.
Random Walk defines data boundaries, access permissions, evaluation evidence, runtime logs, and ownership from the start of each private AI project.
Boundary
Where data lives, how models use it, how results move.
Training material, dataset packages, model weights, LoRA adapters, fused models, inference environments, external interfaces, and storage locations all belong in the boundary design.
On-prem GPU server
Training and inference inside company-owned compute.
Environment record and operator runbook.
Private cloud
Dedicated private infrastructure with controlled access paths.
Architecture diagram and access notes.
Customer VPC
Deployment inside the customer's own approved cloud boundary.
Data movement register and runtime record.
Air-gapped environment
Systems designed for restricted or disconnected environments.
Transfer procedure, update path, and evidence handling notes.
Edge devices
Inference near devices, operators, sensors, or industrial workflows.
Fleet update model and lightweight runtime notes.
Evidence
The system must leave reviewable evidence.
Data sources, processing steps, training configuration, model fusion, evaluation, deployment versions, call records, and key changes should be traceable.
Constraint registerCaptures privacy, compliance, and deployment constraints.
Dataset manifestDocuments sources, transformations, exclusions, and retention.
Training run recordCaptures model, dataset, adapter, runtime, and parameters.
Evaluation reportPreserves behavior tests, benchmark results, failures, and limits.
Deployment runbookExplains installation, access, monitoring, rollback, and ownership.
Change logTracks model, data, adapter, and runtime changes over time.
Responsibility
Every capability needs clear ownership.
We define who provides data, who approves use, who maintains environments, who reviews evaluation, and who makes release decisions. Systems with unclear ownership do not last.
Random Walk contribution
Architecture, access-path design, deployment runbooks, evaluation evidence, documentation packages, and customer-side review support.
Customer / advisor responsibility
Legal basis, policy approval, identity provider policy, user provisioning, internal audit, certification, and regulatory filings.
Compliance-aware engineering support. Formal legal, regulatory, and certification determinations remain with the customer and qualified advisors.
