The custom Apex layer is responsible for enforcing Salesforce security; the Lightning component does not automatically make server-side data access safe. The valid runtime control among the choices is the Apex security mechanism that checks or enforces the user ' s access before data is returned or changed. Field-Level Security must be respected for sensitive values such as Shipment Amount, and the record-sharing model must also be enforced so a Private OWD is not bypassed. Schema Describe checks such as isAccessible(), isCreateable(), and isUpdateable() can be used for explicit field and object permission checks. Current secure-Apex patterns also include user-mode database operations and Security.stripInaccessible(), which can enforce or sanitize CRUD/FLS more comprehensively. Record visibility is a separate layer and should be preserved with the appropriate sharing context. System.runAs() is a testing facility, not a production authorization mechanism, and isShareable is not a valid Apex security keyword.

Dynamic Forms is the declarative solution for adapting record presentation without replacing the standard Salesforce page with custom Visualforce or Lightning code. It allows administrators to place fields and field sections individually on a Lightning record page and apply visibility rules based on record context or supported device conditions. That is a better fit for form-factor and alignment problems than maintaining custom view-action overrides that detect devices and route users to different layouts. The declarative approach reduces code ownership, regression risk, testing effort, and long-term maintenance while preserving the standard Salesforce record experience. Where the requirement is driven by record type, the same mechanism can show different field sections for different business processes. The architect must still remember that Dynamic Forms controls presentation rather than security: fields that are hidden by component visibility can still be available through reports, list views, APIs, or other interfaces if Field-Level Security grants access. Sensitive information therefore still requires proper FLS.

A criteria-based sharing rule combined with a public group precisely matches the requirement. The records are selected by a business characteristic - whether an Opportunity is high value - while the recipients are a cross-functional set of auditors who do not belong to one common role. The public group provides a stable audience that can be maintained independently, and the criteria-based rule automatically exposes only the Opportunities that meet the defined condition. Placing the auditors at the top of the role hierarchy would grant much broader access and distort the hierarchy ' s organizational purpose. Default Opportunity Teams are tied to deal collaboration and individual owners, so they are not an appropriate enterprise audit mechanism. Starting from a Private OWD and opening only the qualifying records to the auditor group preserves least privilege. Study Guide reference: Access to Records - criteria-based sharing, public groups, Private OWD, cross-functional audit access, and least privilege.

External organization-wide defaults are designed for this exact separation of internal and external access. UC can keep the internal default for ServiceFeedback at the level required by employees while setting Default External Access to Private for authenticated external users. That creates a restrictive baseline for partner users without reducing internal visibility. Sharing rules are additive: they can open access beyond the organization-wide default, but they cannot take away access already granted by a public OWD. For that reason, neither an owner-based nor a criteria-based rule can be used to make external access more restrictive. After the external OWD is Private, UC can selectively grant the required records through the appropriate Experience Cloud mechanism, such as sharing sets, partner roles, sharing rules, or other supported sharing constructs depending on the relationship model. This follows the least-privilege design principle used throughout Salesforce security architecture: establish the most restrictive baseline that satisfies the broad population, then add narrowly scoped exceptions. Study Guide reference: Access to Records - organization-wide defaults, external OWDs, Experience Cloud record access, sharing rules, and least-privilege sharing.

The valid runtime mechanism among the choices is declaring the Apex class with sharing so Salesforce evaluates record-level sharing when the class queries Shipment records. Because the Shipment OWD is Private, Apex that ignores sharing can expose records outside the user ' s intended visibility. The sensitive Shipment Amount introduces a second security layer: with sharing does not enforce object CRUD or Field-Level Security. The implementation must separately enforce field access, for example with user-mode operations, Security.stripInaccessible(), or valid Schema Describe checks. System.runAs() is useful for tests but does not secure production execution, and isShareable is not a valid Apex sharing keyword. The correct architecture therefore combines record-sharing enforcement with explicit CRUD/FLS enforcement instead of assuming one mechanism protects every layer. Study Guide reference: Permissions to Standard Objects, Custom Objects, and Fields - with sharing, Apex execution context, CRUD/FLS, user-mode operations, and secure Lightning/Apex architecture. The implementation should also be validated with representative users so effective permissions, sharing inheritance, and any cross-object access behave exactly as designed before production release.
