Explanation

The direct issue STUDYU-2 requires RBAC roles and RLS policies, participant-email validation through a tested Edge Function, scoped collaborator permissions, supervised request/approve/deny and lock behavior, notifications, audit logging, and an end-to-end workflow test. The whole-PR diff changes only flutter_common/lib/envs/.env.dev to select a Supabase URL and publishable key. It does not implement or test any of these requirements.

Resolution

Implement the STUDYU-2 coding requirements, including the Supabase schema and policies, Edge Function and tests, collaboration permissions, approval workflow, locking, notifications, audit logging, and end-to-end coverage. Alternatively, link this change to the issue that requires the development backend configuration.

Full details: Out of Scope Changes check

Explanation

The changed environment endpoint and publishable key support development backend selection. The direct issue STUDYU-2 defines IAM, collaboration, and supervised publication behavior, but it does not require this backend configuration. The diff contains no code or test that connects these configuration changes to those objectives.

Manual QA: Update dev backend (PR #963)

Summary

This change updates the development environment to use the self-hosted StudyU Supabase backend and its publishable key. It does not change participant or designer UI. The main risks are an incorrect backend URL or an invalid development key. 2 items, all manual-only.

Setup

• Use the development environment configuration from flutter_common/lib/envs/.env.dev.
• Use a network connection that can reach (studyu02.sc.hpi.de/redacted).
• Do not use production credentials or production data for this check.

P1 — Must test

• Confirm the development app reaches the configured Supabase backend

  • Steps:
    1. Load flutter_common/lib/envs/.env.dev.
    2. Start the participant app or designer with the development environment.
    3. Open the first screen that requires Supabase access.
  • Expected: The app starts without a Supabase configuration error. The first Supabase-backed screen loads from the configured development backend.

• Confirm the development backend health endpoint responds

  • Steps:
    1. Read the Supabase URL from flutter_common/lib/envs/.env.dev.
    2. Request the URL with the path /storage/v1/status.
  • Expected: The request returns HTTP status 200. The request uses (studyu02.hpi.de/redacted) and does not use the production backend.

Automated checks

• No package test applies because this change only updates development environment values.

Out of scope

• Participant behavior — no source code under app/ changed.
• Designer behavior — no source code under designer_v2/ changed.
• Production configuration — no production environment file changed.
• UI layout and visual checks — this change has no visual code changes.

This is a short-form scope. Reach for the full template only when the change has user-visible behavior.
