C4 hierarchy path

Current layer: Component, explaining the key responsibility units within a Container.
Upper layer: Container, which defines the architectural boundaries to which these components belong.
Lower layer: Code View, only enter a small number of key code anchors when you need to trace the implementation entrance or change the impact surface.

Responsibility

Explain which key components within the apps/linux_cardputer_zero Container bear architectural responsibilities. The Component layer is not a comprehensive list of classes/functions, only objects that are helpful for understanding system boundaries, collaboration, or the impact of changes.

Boundary

The boundary of Component View is limited to apps/linux_cardputer_zero Container; cross-container relationships should be explained back to the Container or Engineering Sequence perspective.

cardputer_zero_input_method_port: cardputer_zero_input_method_port is the main architectural component within apps/linux_cardputer_zero, evidence from apps/linux_cardputer_zero/src/cardputer_zero_input_method_port.cpp.
cardputer_zero_notification_port: cardputer_zero_notification_port is the main architectural component within apps/linux_cardputer_zero, evidence from apps/linux_cardputer_zero/src/cardputer_zero_notification_port.cpp.

Relationship with business complexity

The component layer helps connect business stories to actual portal, orchestration, adaptation or infrastructure objects.
If a component directly hosts a Use Case, corresponding evidence should appear in the drill-down document of the organization/process model.

Relationship with technical complexity

Corresponds to Engineering Class / Structural Diagram: docs/engineering/class-structural-diagrams/apps-linux_cardputer_zero/class-structural-diagram.html.
Component-level reuse signs, external collaboration signs and complexity candidate points are still explained by the software structure model.

Explanation of elements in the diagram

CardputerZeroNotificationPort

Component · medium

CardputerZeroNotificationPort is a class candidate component in apps/linux_cardputer_zero, and the evidence anchor is apps/linux_cardputer_zero/src/cardputer_zero_notification_port.h#L67; the current warehouse evidence shows that it has signs of partial relationships and is suitable as a candidate anchor rather than a complete conclusion.

Responsibility: CardputerZeroNotificationPort is considered a candidate architecture component in the current C4 Component View. This judgment is not determined by the name alone, but is jointly supported by apps/linux_cardputer_zero/src/cardputer_zero_notification_port.h#L67, class type and local relationship signs, which are suitable as candidate anchors rather than complete conclusions.
Boundary: It belongs inside apps/linux_cardputer_zero Container; collaboration beyond this path should be interpreted back to the Container or Sequence perspective in the software structure model.
Relationship meaning: CardputerZeroNotificationPort was put into Component View because it offloads the architectural responsibilities of apps/linux_cardputer_zero onto an inspectable entry, orchestration, adapter, contract, or shared object. Reuse signs and external collaboration signs are used to indicate whether it is more like a shared core, an external orchestrator, or a normal local object.
Why it belongs to this layer: It has a clear code anchor, but the current explanation target is not the source code details, but how the internal responsibilities of apps/linux_cardputer_zero are split, so it belongs to the C4 Component layer.
Drill-down intention: Drill down to the Component Diagram of the Code View or software structure model to view the file anchor point of CardputerZeroNotificationPort, direct collaboration, and whether there is a risk of change diffusion.

Can drill down to C4

Code anchor: apps/linux_cardputer_zero details

Enter code anchor point: apps/linux_cardputer_zero to trace the architectural responsibility of component responsibility: apps/linux_cardputer_zero to the specific file/symbol anchor point; only when you need to determine the implementation entry or the impact of the change, you should drill down to Code.

Explain a few key code anchors in apps/linux_cardputer_zero from the C4 Code layer. The Code layer is not a code browser and is only used when you need to understand how architectural components fall into specific files/symbols.
