A record update yields one intended side effect even when another plug-in or flow touches the same row. This result validates Plug-in recursion depth and idempotent registration instead of the component in question. Here the specific acceptance check is: Related writes either commit in the intended atomic scope or fail with precise recoverable evidence.

Transient throttling recovers without overwhelming Dataverse or creating duplicate rows. This result validates Dataverse API service-protection throttle retry instead of the component in question. Here the specific acceptance check is: Related writes either commit in the intended atomic scope or fail with precise recoverable evidence.

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: Related writes either commit in the intended atomic scope or fail with precise recoverable evidence.

Inspect environment and agent IDs, user auth, session lifecycle, tool event handling, response streaming and retries. These checks are relevant to Copilot Studio client library consumption, but are not the most discriminating first evidence for this case. Inspect instead: Inspect custom API uniqueness, bound/unbound setting, parameters, Execute privilege, registration and returned response shape.

Inspect token audience/scopes, app registration, app-user Dataverse role, expiration and token cache security. These checks are relevant to OAuth delegated vs client credential in Dataverse, but are not the most discriminating first evidence for this case. Inspect instead: Inspect custom API uniqueness, bound/unbound setting, parameters, Execute privilege, registration and returned response shape.

Inspect trigger type, correlation ID, Dataverse service principal, function timeout, queue visibility and failed-message policy. These checks are relevant to Azure Functions for long-running Dataverse work, but are not the most discriminating first evidence for this case. Inspect instead: Inspect custom API uniqueness, bound/unbound setting, parameters, Execute privilege, registration and returned response shape.

Pass the execution context to registered form handlers and obtain formContext instead of relying on deprecated global Xrm.Page. That action addresses Model-driven formContext from execution context instead. The Client API formContext comes from the event context; standalone Web API calls do not expose a form object. For this case, the targeted action is: Use supported Xrm.Navigation dialogs, notifications and openForm or navigateTo APIs rather than manipulating window location directly.

Register OnChange handlers once, target supported events and prevent event-recursion when setting attribute values programmatically. That action addresses OnChange handlers and loop prevention instead. Setting an attribute value does not always trigger OnChange automatically; explicit event invocation can create loops. For this case, the targeted action is: Use supported Xrm.Navigation dialogs, notifications and openForm or navigateTo APIs rather than manipulating window location directly.

Avoid redundant network calls, unnecessary re-rendering and leaked listeners; use pagination, memoization and cleanup when appropriate. That action addresses Code app render performance and resource cleanup instead. More client-side code and data preloading are not always faster than a filtered delegated server query. For this case, the targeted action is: Use supported Xrm.Navigation dialogs, notifications and openForm or navigateTo APIs rather than manipulating window location directly.

Use configured Dataverse table relationships and a business rule before adding a custom plug-in when requirements fit declarative capabilities. That action addresses Out-of-box table/form choice versus server extension instead. Code introduces deployment and maintenance overhead; client-only rules do not enforce server-side invariants. For this case, the targeted action is: Choose model-driven JavaScript for form interaction, PCF for reusable field/dataset controls, and code apps for a broader custom React-based experience.

Use solution environment variables for per-environment configuration and connection references for connector bindings, rather than hardcoded identifiers or secrets. That action addresses Environment variables and connection references instead. Environment variables are configuration inputs; they do not replace safe credential storage or connector authorization. For this case, the targeted action is: Choose model-driven JavaScript for form interaction, PCF for reusable field/dataset controls, and code apps for a broader custom React-based experience.

Apply Dataverse security roles, teams and business-unit ownership plus application-user permissions to authorize the component at the correct data scope. That action addresses Least-privilege technical authorization design instead. UI hiding and a valid OAuth token alone do not establish Dataverse record authorization. For this case, the targeted action is: Choose model-driven JavaScript for form interaction, PCF for reusable field/dataset controls, and code apps for a broader custom React-based experience.

Avoid redundant network calls, unnecessary re-rendering and leaked listeners; use pagination, memoization and cleanup when appropriate. This step belongs to Code app render performance and resource cleanup rather than the complementary pair here. The required action is: Configure allowed origins for scripts, styles, connections and frames according to the code app CSP rather than setting a permissive wildcard. And its evidence is: Review browser CSP violation logs, required identity endpoints, connector hosts, unsafe-inline usage and approved headers.

Inspect browser network errors, telemetry configuration, sampling, request correlation, exception events and user consent. This step belongs to Code app Application Insights instrumentation rather than the complementary pair here. The required action is: Configure allowed origins for scripts, styles, connections and frames according to the code app CSP rather than setting a permissive wildcard. And its evidence is: Review browser CSP violation logs, required identity endpoints, connector hosts, unsafe-inline usage and approved headers.

The app displays agent results with attributable tool calls and blocks unauthorized record writes. This step belongs to Code app consuming Copilot Studio agent rather than the complementary pair here. The required action is: Configure allowed origins for scripts, styles, connections and frames according to the code app CSP rather than setting a permissive wildcard. And its evidence is: Review browser CSP violation logs, required identity endpoints, connector hosts, unsafe-inline usage and approved headers.

The operation succeeds using its intended identity and forbidden tables remain denied to that principal. This result validates OAuth delegated vs client credential in Dataverse instead of the component in question. Here the specific acceptance check is: The receiving agent produces a traceable response with correct customer scope and no unintended action handoff.

Only relevant table changes start the flow and a self-update does not cause unbounded reentry. This result validates Power Automate Dataverse trigger filter columns and OData instead of the component in question. Here the specific acceptance check is: The receiving agent produces a traceable response with correct customer scope and no unintended action handoff.

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: The receiving agent produces a traceable response with correct customer scope and no unintended action handoff.

Inspect query $select/$filter encoding, returned nextLink, caller role, promises, network failure and lookup logical names. These checks are relevant to Dataverse Xrm.WebApi asynchronous lookups, but are not the most discriminating first evidence for this case. Inspect instead: Inspect build output, managed solution version, component registration, table field compatibility and app publication.

Inspect control manifest property of-type, usage, component namespace, platform libraries and compiled resource paths. These checks are relevant to PCF ControlManifest inputs and resources, but are not the most discriminating first evidence for this case. Inspect instead: Inspect build output, managed solution version, component registration, table field compatibility and app publication.

Inspect manifest features, host capabilities, API permissions, dataset type and PCF solution lifecycle. These checks are relevant to PCF WebAPI Device and Utility usage, but are not the most discriminating first evidence for this case. Inspect instead: Inspect build output, managed solution version, component registration, table field compatibility and app publication.

Use Azure Functions to offload expensive work from synchronous Dataverse plug-ins while authenticating separately and tracking completion. That action addresses Azure Functions for long-running Dataverse work instead. Function execution is not automatically atomic with the Dataverse operation that queued it. For this case, the targeted action is: Authenticate Azure Functions through an eligible managed identity or governed service principal with Dataverse application-user roles.

Expose Power Platform operations to Foundry agents using governed MCP servers and explicit tool schemas, permissions and audit traces. That action addresses Microsoft Foundry agent tool access via MCP servers instead. MCP advertises callable tools; their presence does not override Dataverse role-based authorization. For this case, the targeted action is: Authenticate Azure Functions through an eligible managed identity or governed service principal with Dataverse application-user roles.

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: Authenticate Azure Functions through an eligible managed identity or governed service principal with Dataverse application-user roles.

Use expressions such as coalesce, empty, formatDateTime and guarded JSON parsing with explicit type assumptions. That action addresses Power Automate expressions null coalesce and safe parsing instead. A missing property is not always equivalent to an empty string; expression behavior depends on data type. For this case, the targeted action is: Use delegated OAuth for a signed-in user's work and client credentials with a constrained application user for unattended integration.

Use child flows inside solutions to share reusable logic with declared inputs, outputs and correct run-only connection behavior. That action addresses Child flows and solution connection references instead. An arbitrary standalone flow cannot always be used directly as a solution child flow without the correct trigger and context. For this case, the targeted action is: Use delegated OAuth for a signed-in user's work and client credentials with a constrained application user for unattended integration.

Use the Dataverse Web API with logical names, $select, encoded $filter and @odata.nextLink pagination instead of retrieving unrestricted rows. That action addresses Dataverse OData Web API select filter and pagination instead. A page-size hint or first result set does not guarantee the entire data collection has been returned. For this case, the targeted action is: Use delegated OAuth for a signed-in user's work and client credentials with a constrained application user for unattended integration.

Inspect selected connection ID, connector operation, signed-in user's rights, environment binding and app host context. These checks are relevant to Power Apps code app connectors and environment binding, but are not the most discriminating first evidence for this case. Inspect instead: Inspect command designer placement, selection context, Power Fx formula, app publication and calling user's security role.

Inspect query $select/$filter encoding, returned nextLink, caller role, promises, network failure and lookup logical names. These checks are relevant to Dataverse Xrm.WebApi asynchronous lookups, but are not the most discriminating first evidence for this case. Inspect instead: Inspect command designer placement, selection context, Power Fx formula, app publication and calling user's security role.

Inspect control manifest property of-type, usage, component namespace, platform libraries and compiled resource paths. These checks are relevant to PCF ControlManifest inputs and resources, but are not the most discriminating first evidence for this case. Inspect instead: Inspect command designer placement, selection context, Power Fx formula, app publication and calling user's security role.

Inspect package version, environment, target app sharing, connection references, managed solution components and postdeploy tests. This step belongs to Code app packaging sharing and deployment rather than the complementary pair here. The required action is: Pass the execution context to registered form handlers and obtain formContext instead of relying on deprecated global Xrm.Page. And its evidence is: Inspect event handler properties, passExecutionContext setting, formContext acquisition, loaded form attributes and handler scope.

The failing component is identified with reproducible evidence and a targeted fix, not a broad permissions escalation. This step belongs to Code app Monitor and browser troubleshooting rather than the complementary pair here. The required action is: Pass the execution context to registered form handlers and obtain formContext instead of relying on deprecated global Xrm.Page. And its evidence is: Inspect event handler properties, passExecutionContext setting, formContext acquisition, loaded form attributes and handler scope.

Configure a modern model-driven command with Power Fx visibility/action rules or supported JavaScript, matching permissions and saved state. This step belongs to Command bar Power Fx and JavaScript rules rather than the complementary pair here. The required action is: Pass the execution context to registered form handlers and obtain formContext instead of relying on deprecated global Xrm.Page. And its evidence is: Inspect event handler properties, passExecutionContext setting, formContext acquisition, loaded form attributes and handler scope.
