Maker-checker works when approval is part of execution, not a separate log.

Material actions should be submitted, reviewed, and approved inside the workflow. The approval evidence is produced at the moment of control, not reconstructed later.

• Workflow-native approvals

  Instead of relying on offline sign-off or separate tooling, the operating record captures maker intent, checker decision, timestamps, and the context needed to explain what was reviewed.

• Exception handling without losing evidence

  Overrides and repairs can be time-sensitive. A workflow-native model preserves why the exception occurred, who approved it, and what evidence supports the decision.

Access and segregation of duties should be enforced by role scope, not audited after the fact.

Role-scoped access reduces operational ambiguity. Segregation of duties is strongest when the workflow requires distinct actors for distinct steps.

• Role-scoped access

  A role model expresses what each function can do and prevents accidental permission sprawl. The goal is to restrict sensitive actions to the smallest set of authorized roles.

• Segregation as a workflow shape

  The operating model can require that the maker and checker are distinct roles, so a single actor cannot complete both sides of a material action.

An audit trail is exam-ready when it is the operating history, not an export.

Audit evidence should be queryable by record, actor, time range, and workflow step, with references to the source evidence that supports the state.

• Preserve the lifecycle record

  An event-centered operating history can preserve what happened, when, who performed it, and what record context existed at the moment of action.

• Designed to support record production

  Producing records promptly depends on indexed, attributable history and a consistent evidence model—paired with the firm’s compliance process for what must be retained and produced.

Supervisory evidence is stronger when it is generated by normal operations.

Supervision workflows rely on showing what was reviewed, by whom, and when—especially for exceptions, overrides, and sensitive actions.

• Evidence at the point of control

  When review and approval occur inside the workflow, supervisory evidence is a byproduct of doing the work—not a reporting project the week of an examination.

• Separation of workflow and policy

  The platform can preserve the operating record and evidence trail, while the firm determines supervisory policy, thresholds, and compliance interpretation.

Security baseline for the public architecture model

This page focuses on workflow controls and record evidence rather than implementation specifics.

• Operating baseline

  The security model described here is an operating design: role-scoped access, maker-checker review, explicit exception handling, and audit evidence preserved with the lifecycle record.

• Implementation note

  Implementation details (encryption specifics, infrastructure topology, certifications, and vendor assurances) are environment-dependent and not asserted here. Compliance and security determinations remain with the firm.
