# Component responsibility: apps/linux_cardputer_zero C4 level: Component Status: candidate Confidence: medium Project version: 0.1.30-alpha Git:34aad0bffa2f / main / dirty Updated on: 2026-06-25T09:19:32.800Z ## Positioning Explain the key responsibility units inside apps/linux_cardputer_zero from the C4 Component layer: entry, page, command, interface, registry, adapter or shared object. ## C4 hierarchical 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. ## Relationship - CardputerZeroNotificationPort: CardputerZeroNotificationPort is the main architectural component within apps/linux_cardputer_zero, evidenced by apps/linux_cardputer_zero/src/cardputer_zero_notification_port.h#L67. - CardputerZeroInputMethodPort: CardputerZeroInputMethodPort is the main architectural component within apps/linux_cardputer_zero, as evidenced by apps/linux_cardputer_zero/src/cardputer_zero_input_method_port.h#L39. - NotificationUrgency: NotificationUrgency is a major architectural component within apps/linux_cardputer_zero, as evidenced by apps/linux_cardputer_zero/src/cardputer_zero_notification_port.h#L12. - cardputer_zero_input_method_port: cardputer_zero_input_method_port is the main architectural component within apps/linux_cardputer_zero, as evidenced by 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, evidenced by apps/linux_cardputer_zero/src/cardputer_zero_notification_port.cpp. ## Correlation 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. ## Correlation 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 candidates are still explained by the software structural model. ## C4 Component diagram ```mermaid flowchart TB container["apps/linux_cardputer_zero Container"] component_1["CardputerZeroNotificationPort"] container --> component_1 component_2["CardputerZeroInputMethodPort"] container --> component_2 component_3["NotificationUrgency"] container --> component_3 component_4["cardputer_zero_input_method_port"] container --> component_4 component_5["cardputer_zero_notification_port"] container --> component_5 ``` ## Explanation of elements in the diagram ### CardputerZeroNotificationPort - Level: component - Description: 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. - Relational significance: CardputerZeroNotificationPort is put into the Component View because it offloads the architectural responsibilities of apps/linux_cardputer_zero to an inspectable entry, orchestration, adaptation, 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 to split the internal responsibilities of apps/linux_cardputer_zero, so it belongs to the C4 Component layer. - Drill down intent: Drill down to the Code View or Component Diagram of the software structure model to view the file anchor point of CardputerZeroNotificationPort, direct collaboration, and whether there is a risk of change diffusion. - Confidence: medium - Evidence: - apps/linux_cardputer_zero/src/cardputer_zero_notification_port.h#L67 - Indications of reuse: there are local reuse or dependency clues - Indications of external collaboration: there are local external collaboration clues ### CardputerZeroInputMethodPort - Level: component - Description: CardputerZeroInputMethodPort is a class candidate component in apps/linux_cardputer_zero, and the evidence anchor is apps/linux_cardputer_zero/src/cardputer_zero_input_method_port.h#L39; 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: CardputerZeroInputMethodPort is considered a candidate architecture component in the current C4 Component View.
