<h2>C4 hierarchical path</h2>

<ul>
|
|
<li>Current layer: System Context, explaining the boundaries between the target software system and external participants and external systems.</li>
|
|
<li>Upper level: None, this is the root level of the current C4 tree.</li>

|
|
<h2>Responsibility</h2>
|
|
<p>trail-mate is the currently open and analyzed target project. System Context only observes it as a whole software system, first explains who will use or call it, which external systems it may cooperate with, and then enters the Container layer to explain the internal boundaries.</p>
|
|
</section>
|
|
<section class="semantic-layer" data-praxis-anchor="architecture:c4:boundary" data-praxis-kind="architecture_c4_text">
|
|
<h2>Boundaries</h2>
|
|
<p>System Context must surround the trail-mate target system itself; development tools, model services, document generation processes, and IDE workflows do not belong to the target system business context unless they are part of the implementation of the target project itself.</p>
|

<h2>Relationship</h2>
|
|
<ul>
|
|
<li>trail-mate is the system boundary of the current C4 tree; the internal implementation is only expanded through Container drill-down.</li>
|
|
<li>External users, callers or upstream systems are not named in the current warehouse evidence, so this diagram only retains unnamed external participants and does not use tool-side roles to replace real business roles.</li>
|
|
<li>External systems and third-party services will only be detailed when the warehouse evidence can support them; when the current evidence is insufficient, the unnamed external system placeholder will be retained in the figure and the evidence gap will be marked.</li>

<h2>Relationship with business complexity</h2>
|
|
<ul>
|
|
<li>The organization/process model is responsible for explaining business stories and use cases; System Context only retains the external roles or external system entrances for these business capabilities to enter the system boundary.</li>
|
|
<li>If the business actor or business external system has not been confirmed by the document, this diagram must be marked as a candidate, and tool-side roles must not be used to replace the real business context.</li>

<ul>

|
<li>The software structure model identified 18 packages/modules, 24 components and 18 complexity candidate points based on local warehouse evidence.</li>
|
|
<li>System Context is the top-level entrance to the architectural view; only after continuing to drill down to 5 Containers can the system boundaries be reduced to inspectable applications, services, data storage or running units.</li>

<small>apps/linux_sim_shell is a candidate boundary for the C4 Container layer: it must behave as an application, service, data store, runnable unit, or independently deployable/executable system part, rather than a normal directory, code layering, or shared collection of tools.</small>
