[EPIC](Heureka): Go Live With False Positive Remediation — Error Handling, UX, Auth & Testing

[hodanoori]

Description

This epic covers all remaining work required to make the False Positive remediation workflow production‑ready by the end of Q1. The focus is on stabilizing the revert and mark‑false‑positive actions with proper error handling, implementing UX refinements, ensuring user identification and authentication are in place for all remediation actions, and adding the missing automated tests necessary for a reliable go‑live. Additionally, UI behavior must immediately reflect a successful false‑positive action by moving the vulnerability into the remediated list, compensating for slow backend updates.

Objectives

• Ensure mark‑false‑positive and revert actions handle backend and UI errors gracefully.
• Refine UX interactions across all remediation actions.
• Ensure user identification and authentication are correctly applied.
• Provide immediate UI feedback after marking as false positive.
• Complete end‑to‑end test coverage for all workflows.

Acceptance Criteria

• Mark‑false‑positive errors display clear, actionable UI messages.
• Revert errors display clear, actionable UI messages.
• UX refinements for dialogs, confirmation messages, and interaction flows are implemented.
• User ID and authentication context is applied and recorded for remediation actions.
• The UI immediately displays the vulnerability in the “Remediated Vulnerabilities” tab after a successful false‑positive action, independent of backend delay.
• Automated tests cover success paths, error scenarios, and authentication behavior.

Tasks

• Verifying error handling for the “Mark False Positive” action (backend + UI).
• Verifying error handling for the “Revert False Positive” action (backend + UI).
• Apply UX refinements for dialogs, tables, panel, error states, confirmation messages, and loading behavior.
• Integrate user identification for both remediation actions and verify authentication handling end to end.
• Add UI-level immediate update: after marking a vulnerability as a false positive, move it instantly to the remediated tab to compensate for slow backend propagation.
• Add automated tests for all updated flows, including error cases and the immediate UI update behavior.

Additional Notes

This epic focuses strictly on production‑readiness and reliability improvements required for the Q1 release.
