Inspect connector table binding, logical name, lookup ID, supported action, filter and returned service error codes. These checks are relevant to Code app Dataverse metadata and table operations, but are not the most discriminating first evidence for this case. Inspect instead: Inspect event handler properties, passExecutionContext setting, formContext acquisition, loaded form attributes and handler scope.

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 event handler properties, passExecutionContext setting, formContext acquisition, loaded form attributes and handler scope.

Inspect build output, managed solution version, component registration, table field compatibility and app publication. These checks are relevant to Packaging and deploying PCF in solution, but are not the most discriminating first evidence for this case. Inspect instead: Inspect event handler properties, passExecutionContext setting, formContext acquisition, loaded form attributes and handler scope.

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: Invalid records are rejected with a clear supported error before unnecessary downstream logic runs.

Each intended business interval processes the correct work without silently skipping or replaying chargeable operations. This result validates Azure Functions Timer and queue trigger controls instead of the component in question. Here the specific acceptance check is: Invalid records are rejected with a clear supported error before unnecessary downstream logic runs.

Optional fields do not crash the run and required dates or numbers are validated before updates. This result validates Power Automate expressions null coalesce and safe parsing instead of the component in question. Here the specific acceptance check is: Invalid records are rejected with a clear supported error before unnecessary downstream logic runs.

Use a Dataverse connection authorized by a service principal/application user for unattended flows and configure controlled retries on transient errors. That action addresses Dataverse connector service principal and retry policies instead. A service principal with a connector connection still needs Dataverse security roles; retries should not duplicate business effects. For this case, the targeted action is: Use Dataverse row ETags and If-Match for concurrency-sensitive updates rather than silently overwriting newer edits.

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: Use Dataverse row ETags and If-Match for concurrency-sensitive updates rather than silently overwriting newer edits.

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 Dataverse row ETags and If-Match for concurrency-sensitive updates rather than silently overwriting newer edits.

Create a custom connector to a governed Azure Function API with documented OpenAPI schema, bounded response transforms and monitored errors. This step belongs to Azure Function-backed connector transformation rather than the complementary pair here. The required action is: Configure OAuth or supported API key authentication and policy templates for runtime headers/URLs without placing secrets in app formulas. And its evidence is: Inspect authorization URL, scopes, redirect URI, token audience, policy template rules and deployment connection references.

A failed run resumes from a safe checkpoint without overwriting newer edits or resurrecting deleted rows. This step belongs to Incremental sync conflict and deletion recovery rather than the complementary pair here. The required action is: Configure OAuth or supported API key authentication and policy templates for runtime headers/URLs without placing secrets in app formulas. And its evidence is: Inspect authorization URL, scopes, redirect URI, token audience, policy template rules and deployment connection references.

Inspect registration tool endpoint URL, authentication method, execution mode, delivery logs and returned status codes. This step belongs to Webhook integration endpoint authentication and registration rather than the complementary pair here. The required action is: Configure OAuth or supported API key authentication and policy templates for runtime headers/URLs without placing secrets in app formulas. And its evidence is: Inspect authorization URL, scopes, redirect URI, token audience, policy template rules and deployment connection references.

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: Use a supported Copilot Studio client library to invoke agents from app code while handling sessions, authorization, response events and cancellation.

Configure timer or queue triggers with schedule, delivery guarantees, failure behavior and concurrency suited to the Power Platform job. That action addresses Azure Functions Timer and queue trigger controls instead. Queue-trigger delivery can be repeated; timer schedule state and host execution require monitoring. For this case, the targeted action is: Use a supported Copilot Studio client library to invoke agents from app code while handling sessions, authorization, response events and cancellation.

Evaluate agent tool-choice quality with representative test cases and require human approval for high-impact data writes. That action addresses Agent evaluation and human approval for side effects instead. LLM reasoning is probabilistic; prompt-only prohibitions are not a substitute for enforced tool permissions. For this case, the targeted action is: Use a supported Copilot Studio client library to invoke agents from app code while handling sessions, authorization, response events and cancellation.

Inspect control manifest property of-type, usage, component namespace, platform libraries and compiled resource paths. This step belongs to PCF ControlManifest inputs and resources 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.

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.

Records are created or updated only in intended tables and table choices resolve to supported metadata values. This step belongs to Code app Dataverse metadata and table operations 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 selected connection ID, connector operation, signed-in user's rights, environment binding and app host context. This step belongs to Power Apps code app connectors and environment binding rather than the complementary pair here. The required action is: Package PCF through supported tooling, include built assets in a solution and bind the component to the intended column or dataset. And its evidence is: Inspect build output, managed solution version, component registration, table field compatibility and app publication.

Users launch the intended app revision and access only assigned data; a rollback is available. This step belongs to Code app packaging sharing and deployment rather than the complementary pair here. The required action is: Package PCF through supported tooling, include built assets in a solution and bind the component to the intended column or dataset. And its evidence is: Inspect build output, managed solution version, component registration, table field compatibility and app publication.

And its evidence is: Inspect build output, managed solution version, component registration, table field compatibility and app publication.

Choose a standard Dataverse table for native persistence and offline-style features, and a virtual table when live external rows must remain at their source and provider limitations are accepted. This step belongs to Standard versus virtual Dataverse tables rather than the complementary pair here. The required action is: Use configured Dataverse table relationships and a business rule before adding a custom plug-in when requirements fit declarative capabilities. And its evidence is: Inspect requirement traceability, supported business-rule scope, cross-table validation needs, offline behavior and transaction boundaries.

The UX extension runs in its intended host, remains maintainable and respects platform permissions. This step belongs to Choosing client scripts PCF or code apps rather than the complementary pair here. The required action is: Use configured Dataverse table relationships and a business rule before adding a custom plug-in when requirements fit declarative capabilities. And its evidence is: Inspect requirement traceability, supported business-rule scope, cross-table validation needs, offline behavior and transaction boundaries.

Inspect role privileges at access levels, ownership, team membership, row sharing, managed-environment policy and effective caller identity. This step belongs to Least-privilege technical authorization design rather than the complementary pair here. The required action is: Use configured Dataverse table relationships and a business rule before adding a custom plug-in when requirements fit declarative capabilities. And its evidence is: Inspect requirement traceability, supported business-rule scope, cross-table validation needs, offline behavior and transaction boundaries.

The service accesses only approved rows and forbidden updates fail even when made through a direct Web API call. This result validates Least-privilege technical authorization design instead of the component in question. Here the specific acceptance check is: The rule works for supported users without maintaining custom code and the exception cases remain correct.

A blocked quality gate prevents production import while an approved release is traceable to a specific package hash. This result validates Power Platform pipelines and CI deployment gates instead of the component in question. Here the specific acceptance check is: The rule works for supported users without maintaining custom code and the exception cases remain correct.

The UX extension runs in its intended host, remains maintainable and respects platform permissions. This result validates Choosing client scripts PCF or code apps instead of the component in question. Here the specific acceptance check is: The rule works for supported users without maintaining custom code and the exception cases remain correct.

Each intended business interval processes the correct work without silently skipping or replaying chargeable operations. This step belongs to Azure Functions Timer and queue trigger controls rather than the complementary pair here. The required action is: Move long-running operations to background processing with correlation and safe retries rather than forcing synchronous UI requests to remain open. And its evidence is: Inspect asynchronous request state, queue work item ID, job timeout, concurrency limits and idempotent completion marker.

Inspect connection reference, authentication type, app-user table rights, retry count and 429 handling. This step belongs to Dataverse connector service principal and retry policies rather than the complementary pair here. The required action is: Move long-running operations to background processing with correlation and safe retries rather than forcing synchronous UI requests to remain open. And its evidence is: Inspect asynchronous request state, queue work item ID, job timeout, concurrency limits and idempotent completion marker.

Use IOrganizationService Retrieve/Update/ExecuteRequest operations from a supported server-side context and handle typed Entity logical names. This step belongs to Dataverse Organization Service SDK operations rather than the complementary pair here. The required action is: Move long-running operations to background processing with correlation and safe retries rather than forcing synchronous UI requests to remain open. And its evidence is: Inspect asynchronous request state, queue work item ID, job timeout, concurrency limits and idempotent completion marker.

Use Application Insights telemetry with correlation IDs and privacy-safe fields to monitor code-app failures and end-to-end calls. That action addresses Code app Application Insights instrumentation instead. Telemetry needs context and privacy controls; a page-view count cannot diagnose specific failed API calls. For this case, the targeted action is: Use PCF context.webAPI, device and utility features only where supported by the intended host; fall back gracefully when unavailable.

Declare bound/input properties and resource files correctly in ControlManifest.Input.xml and align TypeScript output shapes with metadata. That action addresses PCF ControlManifest inputs and resources instead. PCF manifests are contracts for host binding; TypeScript property names alone do not register fields. For this case, the targeted action is: Use PCF context.webAPI, device and utility features only where supported by the intended host; fall back gracefully when unavailable.

Read environment variables via supported Power Platform mechanism and keep endpoints, feature flags and tenant configuration separate from code. That action addresses Code app environment variables and release-specific config instead. Client-exposed configuration must not contain secrets; environment variables do not make embedded keys confidential. For this case, the targeted action is: Use PCF context.webAPI, device and utility features only where supported by the intended host; fall back gracefully when unavailable.
