Inspect evaluator cases, tool traces, policy refusal tests, human approval status, error rates and rollback evidence. These checks are relevant to Agent evaluation and human approval for side effects, but are not the most discriminating first evidence for this case. Inspect instead: Inspect environment and agent IDs, user auth, session lifecycle, tool event handling, response streaming and retries.

Inspect data connection, access control, relevance filters, record freshness, approved tools and response trace. These checks are relevant to Work IQ grounded Dataverse access for agents, but are not the most discriminating first evidence for this case. Inspect instead: Inspect environment and agent IDs, user auth, session lifecycle, tool event handling, response streaming and retries.

Inspect identity object ID, token audience, Dataverse app user, table privileges, role assignments and secret usage. These checks are relevant to Managed identity Azure Function to Dataverse, but are not the most discriminating first evidence for this case. Inspect instead: Inspect environment and agent IDs, user auth, session lifecycle, tool event handling, response streaming and retries.

A function retrieves only authorized Dataverse rows without shipping plaintext client secrets in configuration. This step belongs to Managed identity Azure Function to Dataverse rather than the complementary pair here. The required action is: Use expressions such as coalesce, empty, formatDateTime and guarded JSON parsing with explicit type assumptions. And its evidence is: Inspect trigger outputs, actual null/empty shapes, dynamic content paths, expression result and test payloads.

Inspect execution depth, parent context, plugin registration stages, update attributes and processing marker. This step belongs to Plug-in recursion depth and idempotent registration rather than the complementary pair here. The required action is: Use expressions such as coalesce, empty, formatDateTime and guarded JSON parsing with explicit type assumptions. And its evidence is: Inspect trigger outputs, actual null/empty shapes, dynamic content paths, expression result and test payloads.

Use child flows inside solutions to share reusable logic with declared inputs, outputs and correct run-only connection behavior. This step belongs to Child flows and solution connection references rather than the complementary pair here. The required action is: Use expressions such as coalesce, empty, formatDateTime and guarded JSON parsing with explicit type assumptions. And its evidence is: Inspect trigger outputs, actual null/empty shapes, dynamic content paths, expression result and test payloads.

A function retrieves only authorized Dataverse rows without shipping plaintext client secrets in configuration. This result validates Managed identity Azure Function to Dataverse instead of the component in question. Here the specific acceptance check is: Long-running processing completes independently of the initiating save and reports its final status later.

Multiple parent flows call the same versioned validation step with consistent results and no personal credentials. This result validates Child flows and solution connection references instead of the component in question. Here the specific acceptance check is: Long-running processing completes independently of the initiating save and reports its final status later.

The agent reads authorized records and cannot modify a customer account through an undeclared or unapproved tool. This result validates Microsoft Foundry agent tool access via MCP servers instead of the component in question. Here the specific acceptance check is: Long-running processing completes independently of the initiating save and reports its final status later.

Multiple callers invoke one stable server-side command that validates inputs and applies consistent authorization. This result validates Dataverse custom API contract and plug-in execution instead of the component in question. Here the specific acceptance check is: The intended event invokes the correct step exactly once in test and production with traceable package identity.

The application presents agent output in the right user session and aborted requests do not execute delayed unintended writes. This result validates Copilot Studio client library consumption instead of the component in question. Here the specific acceptance check is: The intended event invokes the correct step exactly once in test and production with traceable package identity.

The additional value is saved atomically with the original request without an extra update recursion. This result validates Dataverse PreOperation Target changes instead of the component in question. Here the specific acceptance check is: The intended event invokes the correct step exactly once in test and production with traceable package identity.

Use child flows inside solutions to share reusable logic with declared inputs, outputs and correct run-only connection behavior. This step belongs to Child flows and solution connection references rather than the complementary pair here. The required action is: Use delegated OAuth for a signed-in user's work and client credentials with a constrained application user for unattended integration. And its evidence is: Inspect token audience/scopes, app registration, app-user Dataverse role, expiration and token cache security.

A record update yields one intended side effect even when another plug-in or flow touches the same row. This step belongs to Plug-in recursion depth and idempotent registration rather than the complementary pair here. The required action is: Use delegated OAuth for a signed-in user's work and client credentials with a constrained application user for unattended integration. And its evidence is: Inspect token audience/scopes, app registration, app-user Dataverse role, expiration and token cache security.

Inspect environment and agent IDs, user auth, session lifecycle, tool event handling, response streaming and retries. This step belongs to Copilot Studio client library consumption rather than the complementary pair here. The required action is: Use delegated OAuth for a signed-in user's work and client credentials with a constrained application user for unattended integration. And its evidence is: Inspect token audience/scopes, app registration, app-user Dataverse role, expiration and token cache security.

Inspect flow identifier, connection reference, child input parameters, caller authorization and flow run log. These checks are relevant to Code app use of Power Automate cloud flow, but are not the most discriminating first evidence for this case. Inspect instead: Inspect package version, environment, target app sharing, connection references, managed solution components and postdeploy tests.

Inspect command designer placement, selection context, Power Fx formula, app publication and calling user's security role. These checks are relevant to Command bar Power Fx and JavaScript rules, but are not the most discriminating first evidence for this case. Inspect instead: Inspect package version, environment, target app sharing, connection references, managed solution components and postdeploy tests.

Inspect dataset loading flags, records page, sorting state, paging.hasNextPage and selected record IDs. These checks are relevant to PCF dataset paging and selection behavior, but are not the most discriminating first evidence for this case. Inspect instead: Inspect package version, environment, target app sharing, connection references, managed solution components and postdeploy tests.

Register required pre/post entity images and filtering attributes to compare only relevant changes without an extra retrieve. That action addresses Plug-in preimage postimage and filtering attributes instead. A Target entity can be sparse and an image only contains registered attributes; images do not automatically include all fields. For this case, the targeted action is: In a synchronous PreOperation plug-in modify the Target attributes directly when a field can be set within the transaction instead of issuing a second Update.

Use delegated OAuth for a signed-in user's work and client credentials with a constrained application user for unattended integration. That action addresses OAuth delegated vs client credential in Dataverse instead. A valid Microsoft Entra token does not grant Dataverse table privileges without application-user role assignment. For this case, the targeted action is: In a synchronous PreOperation plug-in modify the Target attributes directly when a field can be set within the transaction instead of issuing a second Update.

Use PreValidation for early validation outside the main database transaction where appropriate and throw InvalidPluginExecutionException for unsupported operations. That action addresses Dataverse PreValidation plug-in and aborting operations instead. PreValidation is often outside the main transaction but may run within an existing parent transaction; verify actual context. For this case, the targeted action is: In a synchronous PreOperation plug-in modify the Target attributes directly when a field can be set within the transaction instead of issuing a second Update.

Design plug-in logic that avoids self-triggering Update loops and guard against repeated processing with idempotent business conditions. That action addresses Plug-in recursion depth and idempotent registration instead. Blocking all depth greater than one can suppress legitimate nested operations; fix the causative loop and design safe checks. For this case, the targeted action is: Register a signed plug-in assembly, target message, step mode/stage and image configuration with supported tooling and deploy it in a solution.

Use delegated OAuth for a signed-in user's work and client credentials with a constrained application user for unattended integration. That action addresses OAuth delegated vs client credential in Dataverse instead. A valid Microsoft Entra token does not grant Dataverse table privileges without application-user role assignment. For this case, the targeted action is: Register a signed plug-in assembly, target message, step mode/stage and image configuration with supported tooling and deploy it in a solution.

Use the supported Work IQ and Dataverse integration context to ground agent responses in accessible enterprise data, with least privilege and citation to records. That action addresses Work IQ grounded Dataverse access for agents instead. Grounded search and tool access are not equivalent to blanket read rights across every table. For this case, the targeted action is: Register a signed plug-in assembly, target message, step mode/stage and image configuration with supported tooling and deploy it in a solution.

Inspect data connection, access control, relevance filters, record freshness, approved tools and response trace. These checks are relevant to Work IQ grounded Dataverse access for agents, but are not the most discriminating first evidence for this case. Inspect instead: Inspect service proxy context, column sets, record IDs, OrganizationRequest type and fault codes.

Inspect request URI, OData filters, prefer header, continuation link, lookup annotation and calling user privileges. These checks are relevant to Dataverse OData Web API select filter and pagination, but are not the most discriminating first evidence for this case. Inspect instead: Inspect service proxy context, column sets, record IDs, OrganizationRequest type and fault codes.

Inspect trigger type, filtering attributes, change type, OData row filter, trigger condition and run history. These checks are relevant to Power Automate Dataverse trigger filter columns and OData, but are not the most discriminating first evidence for this case. Inspect instead: Inspect service proxy context, column sets, record IDs, OrganizationRequest type and fault codes.

Integrate Foundry custom agents with Copilot Studio agents through supported connectors or contracts while preserving identity and handoff context. That action addresses Foundry to Copilot Studio agent orchestration instead. A multi-agent conversation needs explicit context and security boundaries; text from one agent is not trusted instruction for another. For this case, the targeted action is: Use a Dataverse connection authorized by a service principal/application user for unattended flows and configure controlled retries on transient errors.

Use supported Power Platform managed identity for eligible plug-in outbound access and publish business events through configured secure contracts. That action addresses Plug-in managed identity and business events instead. Managed identities reduce secret management but do not grant target resource permissions automatically. For this case, the targeted action is: Use a Dataverse connection authorized by a service principal/application user for unattended flows and configure controlled retries on transient errors.

Use IOrganizationService Retrieve/Update/ExecuteRequest operations from a supported server-side context and handle typed Entity logical names. That action addresses Dataverse Organization Service SDK operations instead. The Organization service runs against Dataverse business rules and caller permissions; object assignments are not yet persisted updates. For this case, the targeted action is: Use a Dataverse connection authorized by a service principal/application user for unattended flows and configure controlled retries on transient errors.

The component builds, is discoverable and binds to expected columns without manifest/schema mismatch. This step belongs to PCF ControlManifest inputs and resources rather than the complementary pair here. The required action is: Invoke a solution-managed cloud flow from a code app with well-defined input/output schemas and bounded timeout/error handling. And its evidence is: Inspect flow identifier, connection reference, child input parameters, caller authorization and flow run log.

Connect a code app to an authorized Copilot Studio agent through a supported client interface while validating user consent and action permissions. This step belongs to Code app consuming Copilot Studio agent rather than the complementary pair here. The required action is: Invoke a solution-managed cloud flow from a code app with well-defined input/output schemas and bounded timeout/error handling. And its evidence is: Inspect flow identifier, connection reference, child input parameters, caller authorization and flow run log.

Inspect manifest features, host capabilities, API permissions, dataset type and PCF solution lifecycle. This step belongs to PCF WebAPI Device and Utility usage rather than the complementary pair here. The required action is: Invoke a solution-managed cloud flow from a code app with well-defined input/output schemas and bounded timeout/error handling. And its evidence is: Inspect flow identifier, connection reference, child input parameters, caller authorization and flow run log.
