Walkthrough
The change adds unique eight-character friend codes to user records and assigns them during signup. It also adds an authenticated endpoint that returns the current user’s friend code and QR deep link.
User stores a non-null friend code with a unique constraint. The generator checks up to ten candidates for availability. Signup and new local test users receive generated codes. Migration V37 assigns codes to existing users and adds the constraints. Tests cover generation and migration behavior.

The authenticated GET /api/v1/friends/me/code endpoint returns the current user’s friend code and a yeogido://friend?code=... QR value. The service returns USER_NOT_FOUND when no matching user exists. Tests cover the successful and missing-user cases.

Explanation
Issue #416 requirements are implemented. FriendCodeGenerator creates 8-character codes from ABCDEFGHJKLMNPQRSTUVWXYZ23456789 and retries duplicate candidates up to 10 times. AuthServiceImpl and LocalDataInitializer use the generator, and User provides the @PrePersist safeguard. V37 populates existing users, applies NOT NULL and uk_user_friend_code, and retries duplicate groups twice. The authenticated GET /api/v1/friends/me/code endpoint returns friendCode and the yeogido://friend?code=... QR value. The friend structure, FriendErrorCode, generator/service unit tests, and migration integration tests are present.
Full details: Out of Scope Changes check
Explanation
The reviewed changes stay within issue #416. The controller, DTO, converter, service, generator, user persistence changes, signup integration, V37 migration, error codes, and related tests all support friend-code creation or personal friend-code lookup. No unrelated change is established by the available PR summary or reviewed files.
Full details: Docstring Coverage
Explanation
Docstring coverage is 22.22% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 9 functions across 14 files. (1 skipped: 1 unsupported.)
Resolution
Write docstrings for the functions missing them to satisfy the coverage threshold.
