Story Summary

As a maintainer, I want strong backend/API test coverage with automated lint/test checks, so that regressions are caught early and code quality is enforced before
merge.

Problem / Context

Backend route behavior had testing gaps, and CI quality checks needed clearer structure for fast failure and reliable validation.

Scope

In scope:
Add/expand direct tests for backend API route handlers
Add/maintain lint and test CI workflows
Add HTML coverage report generation flow
Keep testing audit current with coverage status
Out of scope:
Broad feature refactors not required for testability
Non-backend/UI-focused test expansion

Acceptance Criteria

Given API route handlers under next/app/api/**/route.ts, when the test suite runs, then all route files have direct test coverage.
Given a pull request to protected branches, when CI executes, then lint and test workflows run and report status.
Given developers need coverage visibility, when npm run test:report is executed, then an HTML report is generated and accessible.

Implementation Tasks

Add/expand route-level tests to close backend API gaps.
Add/update CI workflows for lint and test (with sensible trigger/filter settings).
Add/verify test report script and update testing audit documentation.

Testing Notes

New/updated tests identified
Manual test steps listed

Definition of Done

Acceptance criteria met
Linked PR is merged to dev
Docs updated if setup/process/behavior changed
Project board status moved to Done
