QA perspective: Agent screenshot memory should preserve logic, not old fixes

The author proposes a QA acceptance case for agent screenshot debugging, arguing that memory should store "diagnostic logic" rather than "old fixes."
Scenario:
- Case 1: Deploy button disabled due to missing region field.
- Case 2: Button looks identical but is disabled because the account is read-only.
Core Argument:
If the agent remembers the specific fix from Case 1 ("fill region") and applies it to Case 2, it fails. The useful memory is the general diagnostic logic ("inspect why the button is disabled"), not a screenshot-specific answer.
Methodology:
- Using EvoX to test cross-task experience.
- Keeps context like screenshots, DOM state, and account role.
- Pass: Agent checks the reason and ignores the region field.
- Fail: Agent repeats the old fix due to visual similarity.
The test defines Pass/Fail criteria and awaits client support for experience tracing.
