How to read pictures

This Sequence Diagram focuses on the technical collaboration fragment of startEsp32LvglLoopRuntime calling canStartEsp32LvglLoopRuntime.
It describes a partial running segment and is not necessarily equivalent to the complete business process.
The current relationship comes from local call evidence; without Use Case Trace, it only represents a local collaboration fragment and is not directly equivalent to the main success scenario, callback, compensation or failure path.

Technical complexity analysis

There is a calls relationship between apps/esp32_lvgl/src/esp32_lvgl_loop_runtime.cpp and apps/esp32_lvgl/src/esp32_lvgl_loop_runtime.cpp, and the technical boundary is apps/esp32_lvgl.
Sequence Diagram is used to explain runtime or collaboration sequences, and is suitable for undertaking dynamic behaviors that are unclear from the Package/Component diagram.
If future evidence shows that there are asynchronous messages, callbacks, timeouts or failure compensation, multiple sequences should be broken out for the same business/technical scenario rather than crammed into one big picture.

Relationship with business complexity

The main success path, failure path and callback path of the business Use Case will eventually fall on several technical sequence fragments.
The current fragment may explain the technical execution steps in a certain business story; if there is no Use Case Trace, it will only serve as a local collaboration fragment in the software structure model.
If it is confirmed to belong to a Use Case, the project sequence document should be linked to the corresponding drill-down Sequence Diagram in docs/design.

Governance suggestions

Don't just judge the complete call chain based on a single relationship; you need to combine the upstream and downstream relationships to complete the scenario.
When the sequence involves external systems, model calls, file writes, or Git operations, failure paths and retry/compensation instructions should be supplemented.
If the sequence supports user-visible functions, the business drill-down diagram of the organization/process model should be maintained simultaneously.

Drill down on semantic elements in the diagram

startEsp32LvglLoopRuntime component
startEsp32LvglLoopRuntime is the source participant of the current Sequence Diagram, used to explain startEsp32LvglLoopRuntime calls in apps/esp32_lvgl/src/esp32_lvgl_loop_runtime.cpp canStartEsp32LvglLoopRuntime.

Technical roles
Message originator/relying party: It triggers or references the target capability.

Why it appears
Local warehouse evidence calls were observed between apps/esp32_lvgl/src/esp32_lvgl_loop_runtime.cpp and apps/esp32_lvgl/src/esp32_lvgl_loop_runtime.cpp, so startEsp32LvglLoopRuntime was put into sequence.

Relationship meaning
startEsp32LvglLoopRuntime -> canStartEsp32LvglLoopRuntime indicates the dependency direction of the current fragment; if the relationship is only import, it can only indicate static dependencies and cannot directly prove the runtime order.

Drill-down intention
Drilling down startEsp32LvglLoopRuntime can view the corresponding Component Diagram or structural context to determine the responsibilities of this participant in the larger technical boundary.

Business correlation
The execution process of the business Use Case may fall on multiple sequence fragments; the current fragment is only a candidate technical step and requires organizational/process model evidence to confirm the business meaning.

Change impact
Modifying apps/esp32_lvgl/src/esp32_lvgl_loop_runtime.cpp may change the sequence's dependencies, call evidence, and interpretation of related component/structure diagrams.

- Official module: apps/esp32_lvgl
Risk
- A single sequence fragment is not enough to prove the complete call chain or the successful path of the business main.
Problem
- The current relationship type needs to be distinguished by evidence between runtime calls, static imports, type references, or configuration references; if it is only a static relationship, this diagram should not be interpreted as a real calling sequence.
canStartEsp32LvglLoopRuntime component
canStartEsp32LvglLoopRuntime is the target participant of the current Sequence Diagram and is used to interpret startEsp32LvglLoopRuntime calls in apps/esp32_lvgl/src/esp32_lvgl_loop_runtime.cpp. canStartEsp32LvglLoopRuntime.

Technical roles
Message receiving/relying party: It provides the ability to be referenced or called by the current fragment.

Why it appears
Local repository evidence calls were observed between apps/esp32_lvgl/src/esp32_lvgl_loop_runtime.cpp and apps/esp32_lvgl/src/esp32_lvgl_loop_runtime.cpp, so canStartEsp32LvglLoopRuntime was put into sequence.

Relationship meaning
startEsp32LvglLoopRuntime -> canStartEsp32LvglLoopRuntime indicates that the target capability is dependent on the current fragment; it needs to be combined with the call evidence to confirm whether it is a runtime call, a type reference or a static import.
