• Architecturally prominent files are ranked from entry points and role-named declarations; resource-only paths are omitted.
• Primary languages: Python.
• The verified tree contains 0 project/configuration file(s) and 0 source declaration(s).

Reference code

upload-preview.py:347 — architecture anchor

if __name__ == "__main__":
    if len(sys.argv) != 7:
        die(-1, "usage: python3 upload-preview.py {bundle id} {platform} {version} {locale} "
                "{preview type} {file path}")
    upload(sys.argv[1], sys.argv[2], sys.argv[3], sys.argv[4], sys.argv[5], sys.argv[6])

Interpretation

The arrows summarize the source-visible entry, role-named types or folders, and framework direction; when nodes come from structural folders, the sequence is a high-level interpretation rather than proof that every adjacent node calls the next. Ownership is claimed only where the next section cites a stored property or assignment. The diagram is intentionally limited to the dominant path into App Store Connect API.

Ownership evidence

upload-preview.py:347 — stored dependency or nearest verified ownership anchor

if __name__ == "__main__":
    if len(sys.argv) != 7:
        die(-1, "usage: python3 upload-preview.py {bundle id} {platform} {version} {locale} "
                "{preview type} {file path}")
    upload(sys.argv[1], sys.argv[2], sys.argv[3], sys.argv[4], sys.argv[5], sys.argv[6])

Composition arrows indicate a source-visible construction expression or locally owned value state; aggregation means the owner stores or receives a dependency without proving exclusive lifetime ownership.

Class and protocol design

upload-preview.py:347 — representative type boundary

if __name__ == "__main__":
    if len(sys.argv) != 7:
        die(-1, "usage: python3 upload-preview.py {bundle id} {platform} {version} {locale} "
                "{preview type} {file path}")
    upload(sys.argv[1], sys.argv[2], sys.argv[3], sys.argv[4], sys.argv[5], sys.argv[6])

No local protocol conformance is claimed as protocol-oriented design; external framework conformances are listed only as dependencies.

Access control

Reference code

upload-preview.py:347 — representative boundary

if __name__ == "__main__":
    if len(sys.argv) != 7:
        die(-1, "usage: python3 upload-preview.py {bundle id} {platform} {version} {locale} "
                "{preview type} {file path}")
    upload(sys.argv[1], sys.argv[2], sys.argv[3], sys.argv[4], sys.argv[5], sys.argv[6])

Swift declarations without a modifier are internal; explicit private, fileprivate, private(set), public, or open entries above are interpreted by language semantics. Objective-C/C samples instead rely on header and implementation boundaries, which are not equivalent to Swift lexical privacy.

Logic ownership and placement

Design patterns

Naming conventions

• Types: feature-specific names rather than reusable layer suffixes.
• Protocols: no local protocol declaration in the scanned source.
• Methods: upload, does, make_http_request, create_token, die, red, green, blue.
• Files: feature/project roles rather than a strict one-type-per-file rule.

Architecture takeaways

• upload-preview is the main source-visible entry or composition anchor for this sample.
• Framework work reaches App Store Connect API through a deliberately small high-level chain; the detailed API graph remains inside the cited implementation files.
• Stored-property evidence identifies lifecycle collaboration; it does not by itself prove exclusive object ownership.
• Access-control conclusions separate verified language visibility from the likely design rationale.
• The source does not justify labeling the design protocol-oriented.
