Visual Difference Score Assessment
edit
Current Status:
edit
Pixel Perfect Rendering : Achieved for 95.7% of approximately 6250 talk pages tested.
Minor Issues : 99.9% of pages show pixel perfect or only minor vertical whitespace shifts.
Known Differences : 0.1% of pages have known differences (not planned for fixing).
Critical Differences : None.
Considerations for Deployment:
edit
Reliability : The high percentage of pixel-perfect rendering (98.55%) is a strong indicator of the system’s reliability.
Pending Reassessment : None
Blocker Evaluation : None
Extension and Functionality Support
edit
Critical Extensions:
edit
Assumption : Extensions critical for Wikitech DiscussionTools are presumed to be identified in the visual diff process.
Functionality Concerns:
edit
Login vs. Logout Issue : None
Legacy Parser Compatibility : A strategy is needed to ensure that deployment of the new system does not disrupt the recording of metadata by the legacy parser.
Rollback Strategy
edit
Procedure : A full rollback is planned if any significant issues are observed post-deployment.
Main Concerns and Potential Delay
edit
Current Stance : As of now, there are no major concerns that would necessitate postponing the deployment.
Dependent Factors : None.
Proposed Confidence Score for Deployment
edit
Score : Confidence in the rollout is extremely high.
